Background The extent to which adult height, a biomarker of the interplay of genetic endowment and early-life experiences, is related to risk of chronic diseases in adulthood is uncertain.
Methods We calculated hazard ratios (HRs) for height, assessed in increments of 6.5 cm, using individual–participant data on 174 374 deaths or major non-fatal vascular outcomes recorded among 1 085 949 people in 121 prospective studies.
Results For people born between 1900 and 1960, mean adult height increased 0.5–1 cm with each successive decade of birth. After adjustment for age, sex, smoking and year of birth, HRs per 6.5 cm greater height were 0.97 (95% confidence interval: 0.96–0.99) for death from any cause, 0.94 (0.93–0.96) for death from vascular causes, 1.04 (1.03–1.06) for death from cancer and 0.92 (0.90–0.94) for death from other causes. Height was negatively associated with death from coronary disease, stroke subtypes, heart failure, stomach and oral cancers, chronic obstructive pulmonary disease, mental disorders, liver disease and external causes. In contrast, height was positively associated with death from ruptured aortic aneurysm, pulmonary embolism, melanoma and cancers of the pancreas, endocrine and nervous systems, ovary, breast, prostate, colorectum, blood and lung. HRs per 6.5 cm greater height ranged from 1.26 (1.12–1.42) for risk of melanoma death to 0.84 (0.80–0.89) for risk of death from chronic obstructive pulmonary disease. HRs were not appreciably altered after further adjustment for adiposity, blood pressure, lipids, inflammation biomarkers, diabetes mellitus, alcohol consumption or socio-economic indicators.
Conclusion Adult height has directionally opposing relationships with risk of death from several different major causes of chronic diseases.

2.  The effect of neoadjuvant radiation therapy on perioperative outcomes among patients undergoing resection of retroperitoneal sarcomas☆ 
Surgical oncology  2014;23(3):155-160.
Background
Neoadjuvant radiation therapy (RT) has several theoretical benefits in the treatment of retroperitoneal sarcoma (RPS), but concerns remain about treatment toxicity and perioperative morbidity. There are limited data regarding its effect on perioperative outcomes, most of which come from small, single-institution series. The purpose of this study was to evaluate the short-term (30-day) postoperative morbidity and mortality associated with neoadjuvant RT following resection of RPS.
Methods
The 2005–2011 National Surgical Quality Improvement Program Participant User File was queried for patients undergoing RPS resection. Subjects were stratified by use of neoadjuvant RT. Perioperative variables and short-term 30-day outcomes were compared. Groups were then propensity matched using a 2:1 nearest-neighbor algorithm and multivariable logistic regression was performed to assess neoadjuvant RT as a predictor of short-term 30-day outcomes.
Results
A total of 785 patients were identified. Neoadjuvant RT was administered to 71 (9.0%). Patients who received neoadjuvant RT were slightly younger (56 vs. 62 years, p < 0.001), but otherwise the groups were similar. After propensity matching, all baseline characteristics were highly similar. Median operative time was longer in the neoadjuvant RT group (279 vs. 219 min, p < 0.01), but there were no differences in mortality (1.4 vs. 2.1%, p = 0.71), major complications (28.2 vs. 25.2%, p = 0.69), overall complications (35.2 vs.33.2%, p = 0.83), early reoperation (5.6 vs. 7.4%, p = 0.81), or length of stay (7 vs. 7 days, p = 0.56). Following further adjustment with logistic regression, we confirmed that there were no differences in 30-day mortality or morbidity between patients who did and did not receive neoadjuvant RT.
Conclusions
Neoadjuvant RT does not appear to increase short-term (30-day) morbidity or mortality following resection of RPS. Continued investigation is needed to better define the role for radiation therapy among patients with this disease.

3.  Substance use disorders and psychiatric comorbidity in mid and later life: a review 
Background Globally, adults aged 65 years or older will increase from 516 million in 2009 to an estimated 1.53 billion in 2050. Due to substance use at earlier ages that may continue into later life, and ageing-related changes in medical conditions, older substance users are at risk for substance-related consequences.
Methods MEDLINE and PsychInfo databases were searched using keywords: alcohol use disorder, drug use disorder, drug misuse, substance use disorder, prescription drug abuse, and substance abuse. Using the related-articles link, additional articles were screened for inclusion. This review focused on original studies published between 2005 and 2013 to reflect recent trends in substance use disorders. Studies on psychiatric comorbidity were also reviewed to inform treatment needs for older adults with a substance use disorder.
Results Among community non-institutionalized adults aged 50+ years, about 60% used alcohol, 3% used illicit drugs and 1–2% used nonmedical prescription drugs in the past year. Among adults aged 50+, about 5% of men and 1.4% of women had a past-year alcohol use disorder. Among alcohol users, about one in 14 users aged 50–64 had a past-year alcohol use disorder vs one in 30 elder users aged 65+. Among drug users aged 50+, approximately 10–12% had a drug use disorder. Similar to depressive and anxiety disorders, substance use disorders were among the common psychiatric disorders among older adults. Older drug users in methadone maintenance treatment exhibited multiple psychiatric or medical conditions. There have been increases in treatment admissions for illicit and prescription drug problems in the United States.
Conclusions Substance use in late life requires surveillance and research, including tracking substance use in the racial/ethnic populations and developing effective care models to address comorbid medical and mental health problems.

4.  Conditional Disease-Free Survival After Surgical Resection of Gastrointestinal Stromal Tumors 
JAMA surgery  2015;150(4):299-306.
IMPORTANCE
Gastrointestinal stromal tumors (GISTs) are the most commonly diagnosed mesenchymal tumors of the gastrointestinal tract. The risk of recurrence following surgical resection of GISTs is typically reported from the date of surgery. However, disease-free survival (DFS) over time is dynamic and changes based on disease-free time already accumulated following surgery.
OBJECTIVES
To assess the comparative performance of established GIST recurrence risk prognostic scoring systems and to characterize conditional DFS following surgical resection of GISTs.
DESIGN, SETTING, AND PARTICIPANTS
A retrospective cohort study of 502 patients who underwent surgery for a primary, nonmetastatic GIST between January 1, 1998, and December 31, 2012, at 7 major academic cancer centers in the United States and Canada.
MAIN OUTCOMES AND MEASURES
Disease-free survival of the patients was classified according to 5 prognostic scoring systems, including the National Institutes of Health criteria, modified National Institutes of Health criteria, Memorial Sloan Kettering Cancer Center GIST nomogram, and American Joint Committee on Cancer gastric and nongastric categories. The concordance index (also known as the C statistic or the area under the receiver operating curve) of established GIST recurrence risk prognostic scoring systems. Conditional DFS estimates were calculated.
RESULTS
Overall 1-year, 3-year, and 5-year DFS following resection of GISTs was 95%, 83%, and 74%, respectively. All the prognostic scoring systems had fair prognostic ability. For all tumor sites, the American Joint Committee on Cancer gastric category demonstrated the best discrimination (C = 0.79). Using conditional DFS, the probability of remaining disease free for an additional 3 years given that a patient was disease free at 1 year, 3 years, and 5 years was 82%, 89%, and 92%, respectively. Patients with the highest initial recurrence risk demonstrated the greatest increase in conditional survival as time elapsed.
CONCLUSIONS AND RELEVANCE
Conditional DFS improves over time following resection of GISTs. This is valuable information about long-term prognosis to communicate to patients who are disease free after a period following surgery.

5.  Nonmedical Stimulant Use among Young Asian Americans, Native Hawaiians/Pacific Islanders, and Mixed-Race Individuals Aged 12–34 years In the United States 
There are concerns over nonmedical use of prescription stimulants among youths, but little is known about the extent of use among young Asian-Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals—the fastest growing segments of the U.S. population. We examined prevalences and correlates of nonmedical stimulant use (NMSU) and disorder (StiUD) for these underrecognized groups. Whites were included as a comparison. Data were from young individuals aged 12–34 years in the 2005–2012 National Surveys on Drug Use and Health. We used logistic regression to estimate odds of past-year NMSU status. Significant yearly increases in lifetime NMSU prevalence were noted in Whites only. NHs/PIs (lifetime 7.33%, past-year 2.72%) and mixed-race individuals (10.20%, 2.82%) did not differ from Whites in NMSU prevalence (11.68%, 3.15%). Asian-Americans (lifetime 3.83%, past-year 0.90%) had lower prevalences than Whites. In each racial/ethnic group, “Methamphetamine/Desoxyn/Methedrine or Ritalin” was more commonly used than other stimulant groups; “got them from a friend/relative for free” and “bought them from a friends/relative” were among the most common sources. Females had greater odds than males of NMSU (among White, NH/PI, mixed-race individuals) and StiUD (among mixed-race individuals). Young adults (aged 18–25) had elevated odds of NMSU (White, NH/PI); adolescents had elevated odds of StiUD (White, mixed-race). Other substance use (especially marijuana, other prescription drugs) increased odds of NMSU and StiUD. NHs/PIs and mixed-race individuals were as likely as Whites to misuse stimulants. Research is needed to delineate health consequences of NMSU and inform prevention efforts for these understudied, rapidly-growing populations.

6.  A Nomogram to Predict Disease-Free Survival After Surgical Resection of GIST 
Background
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Adjuvant imatinib therapy has resulted in improved disease-free survival (DFS) following resection of primary GIST. The aim of our study was to create a nomogram to predict DFS following resection of GIST.
Method
Using a multi-institutional cohort of patients who underwent surgery for primary GIST at 7 academic hospitals in the USA and Canada between January 1998 and December 2012, a multivariable Cox proportional hazards model predicting DFS was created using backward stepwise selection. A nomogram to predict DFS following surgical resection of GIST was constructed with the variables selected in the multivariable model. We tested nomogram discrimination by calculating the C-statistic and compared the nomogram to four existing GIST prognostic stratification systems.
Results
A total of 365 patients who underwent surgery for primary GIST was included in the study. Using backward stepwise selection, sex, tumor size, tumor site, and mitotic rate were selected for incorporation into the nomogram. The nomogram demonstrated superior discrimination compared to the NIH criteria, modified NIH criteria, and Memorial Sloan-Kettering Nomogram and had similar discrimination to the Miettinen criteria (C-statistic 0.77 vs 0.73, 0.71, 0.71, and 0.78, respectively).
Conclusion
Four independent predictors of recurrence following surgery for primary GIST were used to create a nomogram to predict DFS. The nomogram stratified patients into prognostic groups and performed well on internal validation.

7.  The Epidemiology of Alcohol Use Disorders and Subthreshold Dependence in a Middle-Aged and Elderly Community Sample 
Objective
To estimate one-year prevalence and correlates of alcohol abuse, dependence, and subthreshold dependence (diagnostic orphans) among middle-aged and elderly persons in the United States.
Design
2005–2007 National Surveys on Drug Use and Health.
Method
Sample included 10,015 respondents 50–64 years of age and 6,289 respondents 65+ years of age. Data were analyzed by bivariate and multinomial regression analyses.
Measurements
Sociodemographic variables, alcohol use and DSM-IV abuse and dependence, major depression, nicotine dependence, illicit drug use, and nonmedical use of prescription drugs.
Results
Fifty-one percent of the sample used alcohol during the past year (56% in the 50-64 age group and 43% in the 65+ age group). Overall, 11% (dependence 1.9%, abuse 2.3%, and subthreshold dependence 7.0%) of adults aged 50–64 and about 6.7% (dependence 0.6%, abuse 0.9%, and subthreshold dependence 5.2%) of those aged 65+ reported alcohol abuse, dependence or dependence symptoms. Among past-year alcohol users, 20% (dependence 3.4%, abuse 4.0%, and subthreshold dependence 12.5%) of adults aged 50–64 and 15.4% (dependence 1.3%, abuse 2.1%, and subthreshold dependence 12.0%) of those aged 65+ endorsed alcohol abuse or dependence symptoms. “Tolerance” (48%) and “time spent using” (37%) were the two symptoms most frequently endorsed by the subthreshold group. Compared with alcohol users without alcohol abuse or dependence symptoms, Blacks or Hispanics, and those who had nicotine dependence or used nonmedical prescription drugs had increased odds of subthreshold dependence. Diagnostic orphans also were more likely to engage in binge drinking than the asymptomatic group.
Conclusions
Diagnostic orphans among middle-aged and elderly community adults show an elevated rate for binge drinking and nonmedical use of prescription drugs that require attention from health care providers.

8.  Inflammation and Coagulation as Mediators in the Relationships between Religious Attendance and Functional Limitations in Older Adults 
Journal of aging and health  2014;26(4):679-697.
Objective
To examine inflammation and coagulation, which are positively linked to disability and inversely linked to increased religious attendance, as mediators in the cross-sectional relationships between religious attendance and functional status.
Methods
Frequency of attendance and limitations in basic activities of daily living (ADLs), instrumental activities (IADLs) and mobility were assessed in 1,423 elders.
Results
More frequent attendance was associated with fewer ADL, IADL, and mobility limitations, and with lower levels of inflammation and coagulation including interleukin-6, soluble vascular cell adhesion molecule, and D-dimer. Inflammation and coagulation partially mediated the associations between attendance and function. Eight percent of the effect of attendance on ADL (p=0.014), 5% of the effect on IADL (p=0.003), and 8% of the effect on mobility (p=0.001) limitations was due to inflammation and coagulation.
Discussion
Relationships between attendance and function may be due in part to lower levels of inflammation and coagulation among elders who attend services.

10.  Identifying a National Death Index Match 
American Journal of Epidemiology  2009;170(4):515-518.
Data from the National Death Index (NDI) are frequently used to determine survival status in epidemiologic or clinical studies. On the basis of selected information submitted by the investigator, NDI returns a file containing a set of candidate matches. Although NDI deems some matches as perfect, multiple candidate matches may be available for other cases. Working across data from the Duke University site of the Established Populations for Epidemiologic Studies of the Elderly (EPESE), NDI, and the Social Security Death Index (SSDI), the authors found that, for this Established Populations for Epidemiologic Studies of the Elderly cohort of 1,896 cases born before 1922 and alive as of January 1, 1999, a match on Social Security number plus additional personal information (specific combinations of last name, first name, month of birth, day of birth) resulted in agreement between NDI and Social Security Death Index dates of death 94.7% of the time, while comparable agreement was found for only 12.3% of candidate decedents who did not have the required combination of information. Thus, an easy to apply algorithm facilitates accurate identification of NDI matches.

11.  Long-term Oncologic Outcomes After Neoadjuvant Radiation Therapy for Retroperitoneal Sarcomas 
Annals of surgery  2015;262(1):163-170.
Objective
To evaluate long-term survival among patients undergoing radiation therapy (RT), followed by surgical resection of retroperitoneal sarcomas (RPS).
Background
Despite a lack of level 1 evidence supporting neoadjuvant RT for RPS, its use has increased substantially over the past decade.
Methods
The 1998–2011 National Cancer Data Base was queried to identify patients who underwent resection of RPS. Subjects were grouped by use of neoadjuvant RT. Perioperative variables and outcomes were compared. Multivariable logistic regression was performed to assess predictors of neoadjuvant RT. Groups were propensity matched using a 2:1 nearest neighbor algorithm and short-term outcomes were compared. Finally, long-term survival was evaluated using the Kaplan-Meier method, with comparisons based on the log-rank test.
Results
A total of 11,324 patients were identified. Neoadjuvant RT was administered to 696 patients (6.1%). During the study period, preoperative RT use increased from 4% to nearly 15%. Male sex, tumor size larger than 5 cm, treatment at an academic/research program, and higher tumor grade all predicted neoadjuvant RT administration. After propensity matching, the only difference in baseline characteristics was the use of neoadjuvant chemotherapy. Although neoadjuvant RT was associated with a higher rate of negative margins (77.5% vs 73.0%; P = 0.014), there was no corresponding improvement in 5-year survival (53.2% vs 54.2%; P = 0.695).
Conclusions
Despite the increasing use of neoadjuvant RT for patients with RPS, the survival benefit associated with this treatment modality remains unclear. Continued investigation is needed to better define the role of RT among patients with RPS.

12.  Dysphoria and Anhedonia as Risk factors for Disability or Death in Older Persons: Implications for the Assessment of Geriatric Depression 
Objectives
Either dysphoria (sadness) or anhedonia (loss of interest in usually pleasurable activities) is required for a diagnosis of major depression. While major depression is a known risk factor for disability in older persons, few studies have examined the relationship between the 2 core symptoms of major depression and disability or mortality. Our objective was to examine the relationship between these two core symptoms and time to disability or death
Design
Longitudinal cohort study
Setting and Participants
We used the nationally representative Health and Retirement Study to examine this relationship in 11,353 persons over the age of 62 (mean = 74) followed for up to 13 years.
Measurements
Dysphoria and anhedonia were assessed with the Short Form Composite International Diagnostic Interview. Our outcome measure was time to either death or increased disability, defined as the new need for help in a basic activity of daily living. We adjusted for a validated disability risk index and other confounders.
Results
Compared to subjects without either dysphoria or anhedonia, the risk for disability or death was not elevated in elders with dysphoria without anhedonia (adjusted HR = 1.11, 95%CI = 0.91–1.36). The risk was elevated in those with anhedonia without dysphoria (HR = 1.30, 95%CI = 1.06–1.60) and those with both anhedonia and dysphoria (HR = 1.28, 95%CI = 1.13–1.46).
Conclusion
Our results highlight the need for clinicians to learn whether patients have lost interest in usually pleasurable activities, even if they deny sadness.

13.  Alcohol and Drug Use Disorders among Adults in Emergency Department Settings in the United States 
Annals of Emergency Medicine  2012;60(2):172-180.e5.
Study objective
Improving identification and treatment for substance use disorders (SUDs) is a national priority, but data about various drug use disorders encountered in emergency departments (EDs) are lacking. We examined past-year substance use and SUDs (alcohol, 9 drug classes) among adult ED users. Prevalences of substance use and SUDs among ED non-users were calculated for reference purposes.
Methods
Using data from the 2007–2009 National Surveys on Drug Use and Health, we assessed SUDs among noninstitutionalized adults aged ≥18 years who responded to standardized survey questions administered by audio computer-assisted self-interviewing methods.
Results
Of all adults (N=113,672), 27.8% used the ED in the past year. ED users had higher prevalences than ED non-users of coexisting alcohol–drug use (15.2% vs. 12.1%), drug use (any drug, 16.9% vs. 13.0%; marijuana, 12.1% vs. 9.7%; opioids, 6.6% vs. 4.1%), and alcohol or drug disorders (11.0% vs. 8.5%). Among substance users, the ED group on average spent more days using drugs than the non-ED group; ED users manifested higher conditional rates of SUDs than ED non-users (alcohol or drugs, 15.9% vs. 11.7%; marijuana, 16.6% vs. 13.2%; cocaine, 33.2% vs. 22.3%; opioids, 20.6% vs. 10.0%; stimulants, 18.6% vs. 9.2%; sedatives, 35.0% vs. 4.4%; tranquilizers, 12.4% vs. 5.2%). Regardless of ED use status, substance-using young adults, men, and less-educated adults showed elevated odds of having a SUD.
Conclusion
Drug use is prevalent and combined with high rates of drug use disorders among drug users seen in the ED.

14.  The Use of Radiation Therapy in Well-Differentiated Soft Tissue Sarcoma of the Extremities: An NCDB Review 
Sarcoma  2015;2015:186581.
Objective. This study investigated patterns of utilization of radiation therapy (RT) and correlated this with overall survival by assessing patients with well-differentiated soft tissue sarcoma of the extremity (STS-E) in the National Cancer Database (NCDB). Methods. All patients diagnosed with well-differentiated STS-E between 1998 and 2006 were identified in the NCDB. Patients were stratified by use of surgery alone versus use of adjuvant RT after surgery and analyzed using multivariate analysis, Kaplan-Meier analysis, and propensity matching. Results. 2113 patients with well-differentiated STS-E were identified in the NCDB for inclusion with a mean follow-up time of 74 months. 69% of patients were treated with surgery alone, while 26% were treated with surgery followed by adjuvant RT. Patients undergoing amputation were less likely to receive adjuvant RT. There was no difference in overall survival between patients with well-differentiated STS treated with surgery alone and those patients who received adjuvant RT. Conclusions. In the United States, adjuvant RT is being utilized in a quarter of patients being treated for well-differentiated STS-E. While the use of adjuvant RT may be viewed as a means to facilitate limb salvage, this large national database review confirms no survival benefit, regardless of tumor size or margin status.

15.  Patterns of tobacco use and tobacco-related psychiatric morbidity and substance use among middle-aged and older adults in the United States 
Aging & mental health  2012;16(3):296-304.
Objectives
To examine prevalence of tobacco use and identify psychiatric symptoms and substance use correlates of tobacco use comparing adults 50-64 years of age with those 65+ years of age (N=10,891).
Methods
Data were from the 2008–2009 U.S. National Surveys on Drug Use and Health.
Results
Past-year tobacco use was one-half as frequent among adults aged 65+ years (14.1%) compared to adults aged 50–64 years (30.2%); the latter group surpassed the former in rates of cigarette smoking (24.8 % vs. 10.6%), daily cigarette smoking (16.5% vs. 7.1%), cigar smoking (7.4% vs. 2.3%), and smokeless tobacco use (2.5% vs. 1.7%). Increased odds of cigarette smoking were noted among men, whites, African Americans, and those who had less education, had lower income, were not currently married, or were binge drinkers or illicit/non-medical drug users. In controlled analyses, odds ratio in those 65+ years of age who had smoked during the past year was 2.2 for binge drinking and 3.5 for illicit or non-medical drug use. Odds ratio of binge drinking among those 65+ years of age for cigar smokers during the past year was 3.1. Past year cigarette smoking was not associated with reports of symptoms of depression or anxiety in the 65+ age group.
Conclusions
Tobacco use is less prevalent among adults 65+ years of age yet continues to be strongly associated with binge drinking and illicit or non-medical drug use. Preventive efforts to decrease these substance use problems should include programs to decrease tobacco use.

IMPORTANCE
The value of measuring levels of glycated hemoglobin (HbA1c) for the prediction of first cardiovascular events is uncertain.
OBJECTIVE
To determine whether adding information on HbA1c values to conventional cardiovascular risk factors is associated with improvement in prediction of cardiovascular disease (CVD) risk.
DESIGN, SETTING, AND PARTICIPANTS
Analysis of individual-participant data available from 73 prospective studies involving 294 998 participants without a known history of diabetes mellitus or CVD at the baseline assessment.
MAIN OUTCOMES AND MEASURES
Measures of risk discrimination for CVD outcomes (eg, C-index) and reclassification (eg, net reclassification improvement) of participants across predicted 10-year risk categories of low (<5%), intermediate (5%to <7.5%), and high (≥7.5%) risk.
RESULTS
During a median follow-up of 9.9 (interquartile range, 7.6-13.2) years, 20 840 incident fatal and nonfatal CVD outcomes (13 237 coronary heart disease and 7603 stroke outcomes) were recorded. In analyses adjusted for several conventional cardiovascular risk factors, there was an approximately J-shaped association between HbA1c values and CVD risk. The association between HbA1c values and CVD risk changed only slightly after adjustment for total cholesterol and triglyceride concentrations or estimated glomerular filtration rate, but this association attenuated somewhat after adjustment for concentrations of high-density lipoprotein cholesterol and C-reactive protein. The C-index for a CVD risk prediction model containing conventional cardiovascular risk factors alone was 0.7434 (95% CI, 0.7350 to 0.7517). The addition of information on HbA1c was associated with a C-index change of 0.0018 (0.0003 to 0.0033) and a net reclassification improvement of 0.42 (−0.63 to 1.48) for the categories of predicted 10-year CVD risk. The improvement provided by HbA1c assessment in prediction of CVD risk was equal to or better than estimated improvements for measurement of fasting, random, or postload plasma glucose levels.
CONCLUSIONS AND RELEVANCE
In a study of individuals without known CVD or diabetes, additional assessment of HbA1c values in the context of CVD risk assessment provided little incremental benefit for prediction of CVD risk.

17.  Illicit and Nonmedical Drug Use Among Older Adults: A Review 
Journal of aging and health  2010;23(3):481-504.
Objective
Substance abuse among older adults is a looming public health concern. The number of Americans aged 50+ years with a substance use disorder is projected to double from 2.8 million in 2002–2006 to 5.7 million in 2020. The authors provide a review of epidemiological findings for this understudied area of research by focusing on illicit drug use disorders and nonmedical use of prescription drugs among adults aged 50+ years.
Method
MEDLINE and PsychInfo were searched using keywords drug use, drug abuse, drug misuse, substance use disorder, and prescription drug abuse. Using the relatedarticles link, additional articles were screened for inclusion. This review included articles published between 1990 and 2010.
Result
Results from multiple sources indicated a much higher rate of illicit drug use and nonmedical use of prescription drugs and drug-related treatment admissions for persons 50 to 64 years of age compared with adults 65+ years of age. Rates of treatment admissions involving primary use of illicit and misuse of prescription drugs have increased, while rates involving primary use of alcohol only have decreased. Alcohol, opioids/heroin, and cocaine were more likely than other substances to be associated with treatment use. Limited research data suggested the effectiveness of treatments, especially for women. Furthermore, older adults appeared to be less likely than younger adults to perceive substance use as problematic or to use treatment services.
Discussion
There is robust evidence showing that an increased number of older adults will need substance abuse care in the coming decades. Increasing demands on the substance abuse treatment system will require expansion of treatment facilities and development of effective service programs to address emerging needs of the aging drug-using population.

19.  Illicit and nonmedical drug use among Asian Americans, Native Hawaiians/Pacific Islanders, and mixed-race individuals 
Drug and alcohol dependence  2013;133(2):10.1016/j.drugalcdep.2013.06.008.
Background
The racial/ethnic composition of the United States is shifting rapidly, with non-Hispanic Asian-Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals the fastest growing segments of the population. We determined new drug use estimates for these rising groups. Prevalences among Whites were included as a comparison.
Methods
Data were from the 2005–2011 National Surveys on Drug Use and Health. Substance use among respondents aged ≥12 years was assessed by computer-assisted self-interviewing methods. Respondents’ self-reported race/ethnicity, age, gender, household income, government assistance, county type, residential stability, major depressive episode, history of being arrested, tobacco use, and alcohol use were examined as correlates. We stratified the analysis by race/ethnicity and used logistic regression to estimate odds of drug use.
Results
Prevalence of past-year marijuana use among Whites increased from 10.7% in 2005 to 11.6–11.8% in 2009–2011 (P<0.05). There were no significant yearly changes in drug use prevalences among Asian-Americans, NHs/PIs, and mixed-race people; but use of any drug, especially marijuana, was prevalent among NHs/PIs and mixed-race people (21.2% and 23.3%, respectively, in 2011). Compared with Asian-Americans, NHs/PIs had higher odds of marijuana use, and mixed-race individuals had higher odds of using marijuana, cocaine, hallucinogens, stimulants, sedatives, and tranquilizers. Compared with Whites, mixed-race individuals had greater odds of any drug use, mainly marijuana, and NHs/PIs resembled Whites in odds of any drug use.
Conclusions
Findings reveal alarmingly prevalent drug use among NHs/PIs and mixed-race people. Research on drug use is needed in these rising populations to inform prevention and treatment efforts.

20.  Comorbid substance use disorders with other Axis I and II mental disorders among treatment-seeking Asian Americans, Native Hawaiians/Pacific Islanders, and mixed-race people 
Journal of psychiatric research  2013;47(12):10.1016/j.jpsychires.2013.08.022.
Little is known about behavioral healthcare needs of Asian Americans (AAs), Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race people (MRs)—the fastest growing segments of the U.S. population. We examined substance use disorder (SUD) prevalences and comorbidities among AAs, NHs/PIs, and MRs (N=4572) in a behavioral health electronic health record database. DSM-IV diagnoses among patients aged 1–90 years who accessed behavioral healthcare from 11 sites were systematically captured: SUD, anxiety, mood, personality, adjustment, childhood-onset, cognitive/dementia, dissociative, eating, factitious, impulse-control, psychotic/schizophrenic, sleep, and somatoform diagnoses. Of all patients, 15.0% had a SUD. Mood (60%), anxiety (31.2%), adjustment (30.9%), and disruptive (attention deficit-hyperactivity, conduct, oppositional defiant, disruptive behavior diagnosis, 22.7%) diagnoses were more common than others (psychotic 14.2%, personality 13.3%, other childhood-onset 11.4%, impulse-control 6.6%, cognitive 2.8%, eating 2.2%, somatoform 2.1%). Less than 1% of children aged <12 years had SUD. Cannabis diagnosis was the primary SUD affecting adolescents aged 12–17. MRs aged 35–49 years had the highest prevalence of cocaine diagnosis. Controlling for age at first visit, sex, treatment setting, length of treatment, and number of comorbid diagnoses, NHs/PIs and MRs were about two times more likely than AAs to have ≥2 SUDs. Regardless of race/ethnicity, personality diagnosis was comorbid with SUD. NHs/PIs with a mood diagnosis had elevated odds of having SUD. Findings present the most comprehensive patterns of mental diagnoses available for treatment-seeking AAs, NHs/PIs, and MRs in the real-world medical setting. In-depth research is needed to elucidate intraracial and interracial differences in treatment needs.

21.  Latent Subtypes of Depression in a Community Sample of Older Adults: Can Depression Clusters Predict Future Depression Trajectories? 
Journal of psychiatric research  2013;47(10):1288-1297.
Identifying sources of heterogeneity in late life depression remains an important focus of psychiatric investigation. Community samples are particularly informative since many older adults have clinically significant depressive symptoms but fail to meet criteria for major depression and older adults generally do not seek treatment for their depressive symptoms. The primary data used for these analyses were those collected in a community-based survey of over 3000 adults age 65 or older followed for up to ten years. Depressive symptoms were measured by the Center for Epidemiologic Studies-Depression scale (CES-D). Latent class analysis was used to identify clusters of participants based on their symptom profiles at baseline. Mixed models were used to examine trajectories of CES-D scores based on cluster assignment. A model with three unique clusters best fit the data. Cluster 1 (59%) had a low probability of any symptom endorsement. Cluster 2 (31%) endorsed as a group some negative affect and somatic symptoms but their endorsement of low positive affect did not differ from Cluster 1. Participants in Cluster 3 (10%) had a higher probability of endorsement of all symptoms compared to Clusters 1 and 2. The results did not appreciably differ when symptom severity was included. Cluster assignment was a significant predictor of change in CES-D score over the ten-year follow-up period, and the effects over time differed by sex. Depressive symptom profiles predict the longitudinal course of depression in a community sample of older adults, findings that are important especially in primary care settings.

22.  Tobacco use among Asian Americans, Native Hawaiians/Pacific Islanders, and mixed-race individuals: 2002–2010 
Drug and alcohol dependence  2013;132(0):87-94.
Background
Non-Hispanic Asian Americans, Native Hawaiians/Pacific Islanders (NHs/PIs), and mixed-race individuals are the fastest growing segments of the US population. We examined prevalences and correlates of tobacco use among these understudied groups. Prevalences among whites were included as a comparison.
Methods
Data were drawn from the 2002–2010 National Surveys on Drug Use and Health. Respondents aged ≥12 years were assessed for current (past-month) use of cigarettes, cigars, smokeless tobacco (chewing tobacco, snuff), and pipe tobacco. Respondents’ race/ethnicity, age, sex, household income, government assistance, urbanicity of residence, residential stability, self-rated health, alcohol use, and drug use were examined as correlates.
Results
Between 2002 and 2010, there was a decline in the prevalence of cigarette smoking among whites (26.9% in 2002; 24.3% in 2010) and Asian Americans (18.0% in 2002; 11.1% in 2010). Prevalence of pipe tobacco use among mixed-race individuals increased from 0.2% in 2002 to 1.6% in 2010; there was little change in the prevalence of cigar and smokeless tobacco use in these racial/ethnic groups. Adjusted analyses showed that, compared with Asian Americans, mixed-race individuals had greater odds of using four tobacco products, and NHs/PIs had greater odds of using cigarettes, cigars, and smokeless tobacco. Regardless of race/ethnicity, male sex was a correlate of use of cigars, smokeless tobacco, and pipe tobacco; alcohol and drug use increased the odds of cigarette and cigar smoking.
Conclusions
These new findings show prevalent tobacco use among NHs/PIs and mixed-race individuals, and highlight the importance of including these populations in future research and reporting.

23.  Non-Prescription Use of Pain Relievers Among Middle Aged and Elderly Community Adults: National Survey on Drug Use and Health 
OBJECTIVES
To estimate the frequency, distribution, and correlates of non-prescription use of pain relievers among middle aged and elderly persons in the United States.
DESIGN
Cross-sectional data analysis of a national community survey.
SETTING
The 2005 and 2006 National Surveys on Drug Use and Health (NSDUH).
PARTICIPANTS
10,953 respondents 50 years of age and older (6,717 respondents 50-64 years of age and 4,236 respondents 65+ years of age).
MEASUREMENTS
Social and demographic variables, detailed assessment of non-prescription use (and abuse) of prescription pain relievers (e.g., acetaminophen with codeine, morphine), substance use, major depression, self-reported medical illnesses, and self-rated health.
RESULTS
Non-prescription use of prescription pain relievers was reported by 1.4% of the sample during the past year. Combinations of acetaminophen with hydrocodone or propoxyphene were the most commonly used drugs. Use was associated with younger age (Odds Ratio, OR = 2.39, 95% CI = 1.31–4.36), American Indian/Alaska native (OR = 8.78, 95% CI = 2.50–30.85) and use of marijuana (OR = 7.07, 95% CI = 3.99–12.53). Less than 10% of non-prescription users were abusing these medications or dependent upon them.
CONCLUSION
In a representative sample of middle aged and older adults, non-prescription use of prescription pain relievers is relatively uncommon. Nevertheless, the much higher use among middle aged adults suggests that as this cohort ages, the problem may increase among the elderly.

24.  Smoking cessation behavior in older adults by race and gender: The role of health problems and psychological distress 
Nicotine & Tobacco Research  2009;11(4):433-443.
Introduction:
Initial research on older smokers suggests that a subgroup of smokers with higher levels of psychological distress and health problems may be more likely to quit smoking than older smokers with fewer such problems. The present study, based on prospective data from a biracial sample of older adults (N = 4,162), examined characteristics of older adult smokers by race and gender.
Methods:
The present study uses both cross-sectional and prospective data to examine the association between smoking behavior, smoking cessation, health functioning, and psychological distress in a biracial sample of community-dwelling older adults.
Results:
We found baseline psychological distress to be associated with poor health functioning. Consistent with hypotheses, baseline (Time 1) psychological distress predicted smoking cessation 3 years later (Time 2). Moreover, the change in health problems between Time 1 and Time 2 fully mediated the association between Time 1 distress and smoking cessation.
Discussion:
Smoking cessation behavior of older adults is best explained by higher levels of distress and health problems regardless of race or gender. These findings may have important treatment implications regarding smoking cessation programs among older adults. Older adult smokers with higher levels of psychological distress and health problems may be more motivated to quit smoking than those with fewer such problems. These difficulties should be targeted within the context of the smoking cessation protocol. Also, we identified a subgroup of older smokers who are reporting fairly good health and lower levels of distress and who are less likely to quit smoking. Motivational methods may need to be developed to engage this group in smoking cessation treatment.

25.  Trajectory Classes of Body Mass Index in a Representative Elderly Community Sample 
Background.
It is unclear whether distinct weight-related trajectory classes, differing in course, demographics, and health characteristics, exist in the elderly population.
Methods.
Data came from the 10-year (1986–1996) Duke Established Populations for Epidemiologic Studies of the Elderly study of 3,861 black (54%) and white (46%) participants aged 65–105 years. Latent-class trajectories of body mass index (BMI: kg/m2) based on self-reported weight and height at baseline, 3, 6, and 10 years later were determined using generalized mixture models. Polytomous logistic regression was used to identify baseline demographic and health characteristics that distinguished the trajectories, and 10-year postbaseline data to confirm the findings.
Results.
We identified three trajectories: normal weight (BMI ~24, 27.6% of the sample), overweight (BMI ~26, 65.1%), and obese (BMI ~31, 7.3%). Demographic characteristics distinguished the three trajectories: highest odds of blacks, women, and less education in the obese trajectory, lowest in the normal-weight trajectory. Obese and overweight differed adversely from normal-weight trajectories, but not significantly from each other on cognitive impairment, hypertension, and diabetes. Depressive symptomatology was more prevalent in the obese; they were also younger. There was no association with cancer or heart disease.
Conclusion.
Distinct trajectories and course of BMI were present in this older population. Weight loss increased with increase in BMI class. Although demographic characteristics distinguished all trajectory classes, adverse health characteristics distinguished the overweight and obese classes from the normal-weight class, but not from each other. Problems associated with education and health are present at study entry and should be addressed earlier in life.
