Psychological quality of life (QOL), health-related QOL (HRQOL), and life satisfaction outcomes and their associated risk factors are reviewed for the large cohort of survivors and siblings in the Childhood Cancer Survivor Study (CCSS). This review includes previously published manuscripts that used CCSS data focused on psychological outcome measures, including the Brief Symptom Inventory (BSI-18), the Medical Outcomes Survey Short Form-36 (SF-36), the Cantril Ladder of Life, and other self-report questionnaires. Comparisons and contrasts are made between siblings and survivors, and to normative data when available, in light of demographic/health information and abstracted data from the medical record. These studies demonstrate that a significant proportion of survivors report more symptoms of global distress and poorer physical, but not emotional, domains of HRQOL. Other than brain tumor survivors, most survivors report both good present and expected future life satisfaction. Risk factors for psychological distress and poor HRQOL are female sex, lower educational attainment, unmarried status, annual household income less than $20,000, unemployment, lack of health insurance, presence of a major medical condition, and treatment with cranial radiation and/or surgery. Cranial irradiation impacted neurocognitive outcomes, especially in brain tumor survivors. Psychological distress also predicted poor health behaviors, including smoking, alcohol use, fatigue, and altered sleep. Psychological distress and pain predicted use of complementary and alternative medicine. Overall, most survivors are psychologically healthy and report satisfaction with their lives. However, certain groups of childhood cancer survivors are at high risk for psychological distress, neurocognitive dysfunction, and poor HRQOL, especially in physical domains. These findings suggest targeting interventions for groups at highest risk for adverse outcomes and examining the positive growth that remains despite the trauma of childhood cancer.
Irritable bowel syndrome (IBS) is a chronic, disabling condition that greatly compromises patient functioning. The aim of this study was to assess the impact of a 6-week twice per week Iyengar yoga (IY) program on IBS symptoms in adolescents and young adults (YA) with IBS compared with a usual-care waitlist control group.
Assessments of symptoms, global improvement, pain, health-related quality of life, psychological distress, functional disability, fatigue, and sleep were collected pre- and posttreatment. Weekly ratings of pain, IBS symptoms, and global improvement were also recorded until 2-month follow-up. A total of 51 participants completed the intervention (yoga = 29; usual-care waitlist = 22).
Baseline attrition was 24%. On average, the yoga group attended 75% of classes. Analyses were divided by age group. Relative to controls, adolescents (14–17 years) assigned to yoga reported significantly improved physical functioning, whereas YA (18–26 years) assigned to yoga reported significantly improved IBS symptoms, global improvement, disability, psychological distress, sleep quality, and fatigue. Although abdominal pain intensity was statistically unchanged, 44% of adolescents and 46% of YA reported a minimally clinically significant reduction in pain following yoga, and one-third of YA reported clinically significant levels of global symptom improvement. Analysis of the uncontrolled effects and maintenance of treatment effects for adolescents revealed global improvement immediately post-yoga that was not maintained at follow-up. For YA, global improvement, worst pain, constipation, and nausea were significantly improved postyoga, but only global improvement, worst pain, and nausea maintained at the 2-month follow-up.
The findings suggest that a brief IY intervention is a feasible and safe adjunctive treatment for young people with IBS, leading to benefits in a number of IBS-specific and general functioning domains for YA. The age-specific results suggest that yoga interventions may be most fruitful when developmentally tailored.

Adult survivors of childhood cancer are at-risk for suicide ideation, though longitudinal patterns and rates of recurrent suicide ideation are unknown. We investigated the prevalence of late report (i.e. post-initial assessment) and recurrent suicide ideation in adult survivors of childhood cancer, identified predictors of suicide ideation, and examined associations among suicide ideation and mortality.
Participants included 9,128 adult survivors of childhood cancer and 3,082 sibling controls enrolled in the Childhood Cancer Survivor Study who completed a survey question assessing suicide ideation on one or more occasions between 1994 and 2010. Suicide ideation was assessed using the Brief Symptom Inventory-18. Mortality data was ascertained from the National Death Index.
Survivors were more likely to report late (Odds Ratio (OR) =1.9; 95% Confidence Interval (CI) =1.5–2.5) and recurrent suicide ideation (OR=2.6, 95% CI=1.8–3.8) compared to siblings. Poor physical health status was associated with increased risk of suicide ideation in survivors (late report: OR=1.9, 95% CI=1.3–2.7; recurrent: OR=1.9, 95% CI=1.2–2.9). Suicide ideation was associated with increased risk for all-cause mortality (Hazard Ratio (HR) =1.3, 95% CI=1.03–1.6) and death by external causes (HR=2.4, 95% CI=1.4–4.1).
Adult survivors of childhood cancer are at-risk for late report and recurrent suicide ideation, which is associated with increased risk of mortality. Routine screening for psychological distress in adult survivors appears warranted, especially for survivors who develop chronic physical health conditions.

Conditioned pain modulation (CPM) refers to the diminution of perceived pain intensity for a test stimulus following application of a conditioning stimulus to a remote area of the body, and is thought to reflect the descending inhibition of nociceptive signals. Studying CPM in children may inform interventions to enhance central pain inhibition within a developmental framework. We assessed CPM in 133 healthy children (mean age = 13 years; 52.6% girls) and tested the effects of sex and age. Participants were exposed to four trials of a pressure test stimulus before, during, and after the application of a cold water conditioning stimulus. CPM was documented by a reduction in pressure pain ratings during cold water administration. Older children (12–17 years) exhibited greater CPM than younger (8–11 years) children. No sex differences in CPM were found. Lower heart rate variability (HRV) at baseline and after pain induction was associated with less CPM controlling for child age. The findings of greater CPM in the older age cohort suggest a developmental improvement in central pain inhibitory mechanisms. The results highlight the need to examine developmental and contributory factors in central pain inhibitory mechanisms in children to guide effective, age appropriate, pain interventions.

To describe alcohol consumption patterns and risk factors for heavy alcohol use among siblings of childhood cancer survivors compared to survivors and national controls.
Secondary analysis of prospectively collected data from two national surveys was performed including a cohort of 3,034 adult siblings of childhood cancer survivors (age 18-56 years) and 10,398 adult childhood cancer survivors both from the Childhood Cancer Survivor Study, plus 5,712 adult participants from the population-based National Alcohol Survey. Cancer-related experiences, self-reported current health and mental health were examined in relation to alcohol consumption patterns including heavy and risky drinking.
Adult siblings of childhood cancer survivors were more likely to be heavy drinkers (ORadj=1.3; 1.0-1.6) and risky drinkers (ORadj=1.3; 1.1-1.6) compared to controls from a national sample. Siblings were also more likely to drink at these two levels compared to survivors. Factors associated with heavy drinking among siblings include being 18-21 years old (ORadj=2.9; 2.0-4.4), male (ORadj=2.3; 1.7-3.0), having a high school education or less (ORadj=2.4; 1.7-3.5), and drinking initiation at a young age (ORadj=5.1; 2.5-10.3). Symptoms of depression, (ORadj=2.1; 1.3-3.2), anxiety (ORadj=1.9; 1.1-3.3) and global psychiatric distress (ORadj=2.5; 1.5-4.3) were significantly associated with heavy alcohol use.
Siblings of children with cancer are more likely to be heavy drinkers as adults compared to childhood cancer survivors or national controls. Early initiation of drinking and symptoms of psychological distress should be identified during early adolescence and effective sibling-specific interventions should be developed and made available for siblings of children with cancer.

Adult survivors of childhood cancer are at risk for long-term morbidities, which may be managed pharmacologically. Psychoactive medication treatment has been associated with adverse effects on specific neurocognitive processes in non-cancer populations, yet these associations have not been examined in adult survivors of childhood cancer.
Outcomes were evaluated in 7,080 adult survivors from the Childhood Cancer Survivor Study using a validated self-report Neurocognitive Questionnaire. Multivariable logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for neurocognitive impairment using demographic and treatment factors and survivors’ report of prescription medication use.
Controlling for cranial radiation, pain, psychological distress, and stroke/seizure, use of antidepressant medications was associated with impaired task efficiency (OR=1.80, 95% CI=1.47–2.21), organization (OR=1.83, 95% CI=1.48–2.25), memory (OR=1.53, 95% CI=1.27–1.84) and emotional regulation (OR=2.06, 95% CI=1.70–2.51). Neuroleptics and stimulants were associated with impaired task efficiency (OR=2.46, 95% CI=1.29–4.69; OR=2.82, 95% CI=1.61–4.93, respectively) and memory (OR=2.08, 95% CI=1.13–3.82; OR=2.69, 95% CI=1.59–4.54, respectively). Anticonvulsants were associated with impaired task efficiency, memory and emotional regulation, although survivors who use these medications may be at risk for neurocognitive impairment on the basis of seizure disorder and/or underlying tumor location (CNS).
These findings suggest that specific psychoactive medications and/or mental health conditions may be associated with neurocognitive function in adult survivors of childhood cancer. The extent to which these associations are causal or indicative of underlying neurological impairment for which the medications are prescribed remains to be ascertained.

Childhood cancer survivors are at-risk for late effects which may be managed pharmacologically. The purpose of this study was to estimate and compare the prevalence of psychoactive medication use of adult survivors of childhood cancer and sibling controls, identify predictors of medication use in survivors, and investigate associations between psychoactive medications and health-related quality of life (HRQOL).
Psychoactive medication use from 1994 to 2010 was evaluated in 10,378 adult survivors from the Childhood Cancer Survivor Study. A randomly selected subset of 3,206 siblings served as a comparison group. Multivariable logistic regression models were used to calculate odds ratios (OR) for baseline and new onset of self-reported psychoactive medication use and HRQOL.
Survivors were significantly more likely to report baseline (22% vs. 15%, p<0.001) and new onset (31% vs. 25%, p<0.001) psychoactive medication use compared to siblings, as well as use of multiple medications (p<0.001). In multivariable models, controlling for pain and psychological distress, female survivors were significantly more likely to report baseline and new onset use of antidepressants (OR=2.66; 95% CI=2.01–3.52; OR=2.02; 95% CI=1.72–2.38, respectively) and multiple medications (OR=1.80; 95% CI=1.48–2.19; OR=1.77; 95% CI=1.48–2.13, respectively). Non-cranial radiation and amputation predicted incident use of analgesics >15 years following diagnosis. Antidepressants were associated with impairment across all domains of HRQOL, with the exception of physical function.
Prevalence of psychoactive medication use was higher among survivors for most medication classes, as was the use of multiple medications. Clinicians should be aware of the possible contribution of psychoactive medications to HRQOL.

To compare the skin and breast/cervical cancer prevention/screening practices of adult siblings of childhood cancer survivors with controls and to identify modifying factors for these practices.
Cross-sectional, self-report data from 2,588 adult siblings of 5+ year survivors of childhood cancer were analyzed to assess cancer prevention/screening practices. Two age, sex and race/ethnicity-matched samples (n=5,915 and n=37,789) of the Behavioral Risk Factor Surveillance System participants served as the comparison populations. Sociodemographic and cancer-related data were explored as modifying factors for sibling cancer prevention/screening practices through multivariable logistic regression.
Compared to controls, siblings were more likely to practice skin cancer prevention behaviors: use of protective clothing (OR 2.85, 95% 2.39-3.39), use of shade (OR 2. 11, 95% 1.88-2.36), use of sunscreen (OR 1.27, 95% 1.14-1.40), and wearing a hat (OR 1.77, 95% 1.58-1.98). No differences were noted for breast/cervical cancer screening including mammography and Pap testing. Having less than a high school education and lack of health insurance were associated with diminished cancer prevention/screening behaviors. Survivor diagnosis, treatment intensity, adverse health, chronic health conditions, and second cancers were not associated with sibling cancer prevention/screening behaviors.
Siblings of cancer survivors report greater skin cancer prevention practices when compared with controls; however, no differences were noted for breast/cervical cancer screening practices. Access to care and lack of education may be associated with decreased cancer prevention/screening behaviors. Interventions are needed to address these barriers.
Research should be directed at understanding the impact of the cancer experience on sibling health behaviors.

Investigations examining psychosocial adjustment among childhood cancer survivors have focused primarily on negative effects and psychopathology. Emergent literature suggests the existence of positive impact or adjustment experienced after cancer, as well. The purpose of this study is to examine the distribution of Perceived Positive Impact (PPI) and its correlates in young adult survivors of childhood cancer.
6,425 survivors and 360 siblings completed a comprehensive health survey, inclusive of a modified version of the Posttraumatic Growth Inventory (PTGI) as a measure of PPI. Linear regression models were used to examine demographic, disease and treatment characteristics associated with PPI.
Survivors were significantly more likely than siblings to report PPI. Endorsement of PPI was significantly greater among female and non-white survivors, and among survivors exposed to at least one intense therapy, a second malignancy or cancer recurrence. Survivors diagnosed at older ages and fewer years since diagnosis were more likely to report PPI. Income, education and marital/relationship status appeared to have varied relationships to PPI depending upon the subscale being evaluated.
The existence and variability of PPI in survivors in this study suggest that individual characteristics, inclusive of race, gender, cancer type, intensity of treatment, age at diagnosis and time since diagnosis, have unique and specific associations with different aspects of perceived positive outcomes of childhood cancer.

Adult studies have demonstrated that increased resting blood pressure (BP) levels correlate with decreased pain sensitivity. However, few studies have examined the relationship between BP and experimental pain sensitivity among children.
This study investigated the association between resting BP levels and experimental pain tolerance, intensity, and unpleasantness in healthy children. We also explored whether these BP–pain relationships were age and gender dependent.
Participants underwent separate 4-trial blocks of cutaneous pressure and thermal pain stimuli, and 1 trial of a cold pain stimulus in counterbalanced order.
A total of 235 healthy children (49.6% female; mean age 12.7 [2.9] years; age range 8–18 years) participated. The study revealed specific gender-based BP–pain relationships. Girls with higher resting systolic BP levels were found to have lower thermal intensity ratings than girls with lower resting systolic BP levels; this relationship was stronger among adolescent girls than among younger girls. Among young girls (8–11 years), those with higher resting diastolic BP (DBP) levels were found to have lower cold intensity and unpleasantness as well as lower thermal intensity ratings than did young girls with lower resting DBP levels; these DBP–pain response relationships were not seen among adolescent girls.
Age, rather than resting BP, was predictive of laboratory pain ratings in boys. The findings suggest that the relationship between BP and experimental pain is age and gender dependent. These aspects of cardiovascular relationships to pain in males and females need further attention to understand their clinical importance.

To identify risk factors for adverse psychological outcomes among adult siblings of long-term survivors of childhood cancer.
Cross-sectional, self-report data from 3,083 adult siblings (mean age 29 years, range 18-56 years) of 5+ year survivors of childhood cancer were analyzed to assess psychological outcomes as measured by the Brief Symptom Inventory-18 (BSI-18). Sociodemographic and health data, reported by both the siblings and their matched cancer survivors were explored as risk factors for adverse sibling psychological outcomes through multivariable logistic regression.
Self-reported symptoms of psychological distress, as measured by the global severity index of the BSI-18, were reported by 3.8% of the sibling sample. Less than 1.5% of siblings reported elevated scores on two or more of the subscales of the BSI-18. Risk factors for sibling depression included having a survivor brother (OR 2.22, 95% CI 1.42-3.55), and having a survivor with impaired general health (OR 2.15, 95% CI 1.18-3.78). Siblings who were younger than the survivor reported increased global psychological distress (OR 1.81, 95% CI 1.05-3.12), as did siblings of survivors reporting global psychological distress (OR 2.32, 95% CI 1.08-4.59). Siblings of sarcoma survivors reported more somatization than did siblings of leukemia survivors (OR 2.07, 95% CI 1.05-3.98).
These findings suggest that siblings of long-term childhood cancer survivors are psychologically healthy in general. There are, however, small subgroups of siblings at risk for long-term psychological impairment who may benefit from preventive risk-reduction strategies during childhood while their sibling with cancer is undergoing treatment.
Rheumatoid arthritis (RA) is a chronic disease characterized by inflammation of joints and associated fatigue, deteriorated range of motion, and impaired psychosocial functioning. Young adults with RA are at a particular risk for compromised health-related quality of life, and there is a need for safe, effective complementary treatment in addition to traditional medical approaches. The aim of the present study was to use face-to-face participant interviews, conducted before and after an Iyengar yoga (IY) program, to examine mechanisms through which yoga may be beneficial to young adults with RA.
This pilot study utilized a single-arm design where all participants received the intervention. Classes were taught twice per week (1.5 hours each) for 6 weeks by an IY teacher qualified in therapeutics. Interview themes included participants’ baseline expectations about yoga and viewpoints as to how their functioning had been impacted by the IY intervention were examined. Five young adults with RA aged 24–31 years (mean = 28; 80% female) completed the yoga intervention. Participants consistently reported that yoga helped with energy, relaxation and mood and they discussed perceived mechanisms for how yoga impacted well-being. Mechanisms included physical changes such as range of motion and physiological awareness, and psychospiritual developments such as acceptance, coping, self-efficacy and mindfulness. Though the study is limited, participants’ responses provide compelling evidence that IY for RA patients is an intervention worthy of further exploration. The mechanisms and outcomes reported by participants support a biopsychosocial model, which proposes that yoga benefits patients through both physiological and psychospiritual changes.

Children, adolescents, and young adults do not typically feature in clinics, studies, and mainstream notions of chronic pain. Yet many young people experience debilitating pain for extended periods of time. Chronic pain in these formative years may be especially important to treat in order for young patients to maintain life tasks and to prevent protracted disability. The Pediatric Pain Program at the University of California, Los Angeles, is a multidisciplinary treatment program designed for young people with chronic pain and their families. We offer both conventional and complementary medicine to treat the whole individual. This article describes the work undertaken in the clinic and our newly developed Yoga for Youth Research Program. The clinical and research programs fill a critical need to provide service to youth with chronic pain and to scientifically study one of the more popular complementary treatments we offer, Iyengar yoga.

A link between alexithymia and somatization has been widely established, yet little is known about different factors that may influence this relationship. Evidence supporting the idea of psychopathology as a mediator has been presented but not widely tested, particularly in children. The present study examined depressive symptoms as a mediator of alexithymia and somatization in a sample of healthy children in order to better understand the alexithymia-somatization link from a developmental perspective. Results indicated that depression significantly partially mediated this relationship, at least for two facets of alexithymia (difficulty identifying and describing feelings). Possible mechanisms, implications, and directions for future research are discussed.

Little is known about pain among long-term adult survivors of childhood cancers. The study investigated pain prevalence in this population compared with sibling controls and examined pain-related risk factors. Three self-reported pain outcomes including pain conditions, prescription analgesics used, and pain attributed to cancer and treatment were assessed among 10,397 cancer survivors and 3,034 sibling controls from the Childhood Cancer Survivor Study (CCSS). Pain conditions (pain/abnormal sensation, migraines, and other headaches) were reported by 12.3%, 15.5%, and 20.5% of survivors respectively; 16.7% of survivors reported use of prescription analgesics, and 21% attributed pain to cancer and treatment. Risks of reporting pain conditions and using prescription analgesics were higher among survivors than siblings adjusting for sociodemographic factors. Younger age at diagnosis and a history of non-Hodgkin lymphoma, Wilms tumor, or neuroblastoma (compared to leukemia) were associated with greater risk of reporting pain conditions. A history of bone cancer or soft tissue sarcoma (compared to leukemia) was associated with greater risks of using prescription analgesics and cancer-related pain attribution. Non-brain directed scatter irradiation was associated with elevated risk for migraines and cancer-related pain attribution. Female gender and lower educational attainment were associated with increased reports of all three pain outcomes; minority status, unemployment, and being single were associated with greater risks for reporting pain conditions. These findings contribute to the understanding of pain and associated risk factors among adult survivors of childhood cancer and suggest areas of focus for pain intervention.

Research in adult populations has highlighted sex differences in cortisol concentrations and laboratory pain responses, with men exhibiting higher cortisol concentrations and reduced pain responses compared with women. Yet, less is known about the relationship of cortisol concentrations to pain in children.
This study examined associations between sex, cortisol, and pain responses to laboratory pain tasks in children.
Salivary cortisol samples from subjects aged 8 to 18 years were obtained at baseline after entering the laboratory (SCb), after the completion of all pain tasks (SC1), and at the end of the session (SC2), 20 minutes later. Blood cortisol samples were also taken after completion of the pain tasks (BC1) and at the end of the session (BC2), 20 minutes later. Subjects completed 3 counterbalanced laboratory pain tasks: pressure, heat, and cold pressor tasks. Pain measures included pain tolerance, and self-reported pain intensity and unpleasantness for all 3 tasks.
The study included 235 healthy children and adolescents (119 boys, 116 girls; mean age, 12.7 years; range, 8–18 years; 109 [46.4%] were in early puberty; 94 [40.0%] white). Salivary and blood cortisol levels were highly correlated with each other. Salivary cortisol levels for the total sample and for boys and girls declined significantly from SCb to SC1 (P < 0.01), although there were no significant changes from SC1 to SC2. No significant sex differences in salivary or blood cortisol levels were evident at any assessment point. Separate examination of the cortisol–laboratory pain response relationships by sex (controlling for age and time of day) suggested different sex-specific patterns. Higher cortisol levels were associated with lower pain reactivity (ie, increased pressure tolerance) among boys compared with girls at SC1, SC2, and BC1 (SC1: r = 0.338, P = 0.003; SC2: r = 0.271, P = 0.020; and BC1: r = 0.261, P = 0.026). However, higher cortisol levels were related to higher pain response (ie, increased cold intensity [BC2: r = 0.229, P = 0.048] and unpleasantness [BC1: r = 0.237, P = 0.041]) in girls compared with boys.
These findings suggest important sex differences in cortisol–pain relationships in children and adolescents. Cortisol levels were positively associated with increased pain tolerance in boys and increased pain sensitivity in girls.

Lack of health insurance is a key barrier to accessing care for chronic conditions and cancer screening. We examined the influence of insurance type (private, public, none) on survivor-focused and general preventive health care in adult survivors of childhood cancer.
The Childhood Cancer Survivor Study is a retrospective cohort study of childhood cancer survivors diagnosed between 1970–1986. Among 8425 adult survivors, the Relative Risk (RR), 95% confidence interval (CI) of receiving survivor-focused and general preventive health care were estimated for uninsured (n=1390) and publicly insured (n=640), comparing to privately insured (n=6395).
Uninsured survivors were less likely than privately insured to report a cancer-related (adjusted RR=0.83, 95% CI, 0.75–0.91) or a cancer center visit (adjusted RR=0.83, 95% CI, 0.71–0.98). Uninsured survivors had lower levels of utilization in all measures of care in comparison with privately insured. In contrast, publicly insured survivors were more likely to report a cancer-related (adjusted RR=1.22, 95% CI, 1.11–1.35) or a cancer center visit (adjusted RR=1.41, 95% CI, 1.18–1.70) than privately insured. While having a similar utilization level of general health examinations, publicly insured survivors were less likely to report Papanicolaou smear or dental examinations.
Among this large, socioeconomically diverse cohort, publicly insured survivors utilize survivor-focused health care at rates at least as high as survivors with private insurance. Uninsured survivors have lower utilization to both survivor-focused and general preventive health care.

Few studies have focused on identifying predictors of medical consultation for pain in healthy children and adolescents.
This investigation sought to identify parent and child laboratory and non-laboratory predictors of pediatric healthcare utilization for pain problems.
Participants were 210 healthy children and adolescents (102 girls), aged 8–17 years who took part in a laboratory pain session.
Three months after the laboratory session, participants were contacted by telephone to ascertain whether they had experienced pain and whether they had seen a healthcare professional for pain. Zero-order correlations among sociodemographics, child laboratory pain responses, parent physical/mental health status and medical consultation for pain were conducted to identify relevant correlates of pediatric healthcare utilization; these correlates were subjected to multivariate analyses.
Bivariate analyses indicated that higher anticipated pain and bother for the cold pressor task, as well as poorer parent physical health status, were associated with pediatric medical consultation for pain, but only among girls. Sequential logistic regression analyses controlling for child age indicated that only parent physical health status, not the laboratory indicators, significantly predicted healthcare consultation for pain among girls. No parent or child correlates of care-seeking for pain emerged for boys.
The findings suggest that parents’ perceived physical health plays a role in determining whether medical care is sought for pain complaints in healthy girls. These results suggest that interventions to assist parents in managing their own physical health problems may lead to reductions in medical consultation for girls’ pain.

Survivors of childhood acute myeloid leukemia (AML) face increased risks of chronic disease and secondary malignancies. Substance exposure may compound these risks.
Participants were diagnosed with AML at <21 years of age and survived ≥5 years following diagnosis. All underwent chemotherapy alone or followed by autologous BMT (chemo ± autoBMT) or underwent allogeneic BMT (alloBMT) if an HLA-matched related donor was available. Survivors completed a health questionnaire and a Youth Risk Behavior Survey (YRBS).
Of eligible survivors, 117 were ≥18 years of age and completed a YRBS. Survivors were a mean age of 10 years at diagnosis and 24 years at interview. Of the substance exposures assessed by YRBS, tobacco, alcohol, and marijuana were most common. Twenty-two percent (22%) had smoked cigarettes in the last 30 days. One-quarter (25%) reported binge drinking in the last month. None of these exposures varied by treatment group. Less than 10% of survivors reported cocaine, heroin, or methamphetamine use. Men were more likely to report high substance exposure (P = 0.004). Sadness/suicidality score was associated with cancer-related anxiety (P = 0.006) and multiple health conditions (P = 0.006).
This analysis reveals exposure to tobacco, alcohol, and marijuana in young adults with few differences based on treatment received. Survivors with cancer-related anxiety or multiple health conditions were more likely to report sadness/hopelessness.

We sought to measure self-reported neurocognitive functioning among survivors of non-central nervous system (CNS) childhood cancers, overall and compared with a sibling cohort, and to identify factors associated with worse functioning.
In a retrospective cohort study, 5937 adult survivors of non-CNS cancers and 382 siblings completed a validated neuropsychological instrument with subscales in task efficiency, emotional regulation, organization, and memory. Scores were converted to T scores; scores in the worst 10% of siblings’ scores (ie, T score ≥63) were defined as impaired. Non-CNS cancer survivors and siblings were compared with multivariable linear regression and log-binomial regression. Among survivors, log-binomial models assessed the association of patient and treatment factors with neurocognitive dysfunction. All statistical tests were two-sided.
Non-CNS cancer survivors had similar or slightly worse (<0.5 standard deviation) mean test scores for all four subscales than siblings. However, frequencies of impaired survivors were approximately 50% higher than siblings in task efficiency (13.0% of survivors vs 7.3% of siblings), memory (12.5% vs 7.6%), and emotional regulation (21.2% vs 14.4%). Impaired task efficiency was most often identified in patients with acute lymphoblastic leukemia who received cranial radiation therapy (18.1% with impairment), myeloid leukemia who received cranial radiation therapy (21.2%), and non-Hodgkin lymphoma (13.9%). In adjusted analysis, diagnosis age of younger than 6 years, female sex, cranial radiation therapy, and hearing impairment were associated with impairment.
A statistically and clinically significantly higher percentage of self-reported neurocognitive impairment was found among survivors of non-CNS cancers than among siblings.
Recent studies have found that a subset of young adult survivors of childhood cancer report posttraumatic stress symptoms in response to their diagnosis and treatment. However, it is unclear if these symptoms are associated with impairment in daily functions and/or significant distress, thereby resulting in a clinical disorder. Furthermore, it is unknown whether this disorder continues into very long-term survivorship, including the 3rd and 4th decades of life. This study hypothesized that very long-term survivors of childhood cancer would be more likely to report symptoms of posttraumatic stress disorder, with functional impairment and/or clinical distress, compared to a group of healthy siblings.
Patients and Methods
6,542 childhood cancer survivors over the age of 18 who were diagnosed between 1970 and 1986 and 368 siblings of cancer survivors completed a comprehensive demographic and health survey.
589 survivors (9%) and 8 siblings (2%) reported functional impairment and/or clinical distress in addition to the set of symptoms consistent with a full diagnosis of Posttraumatic Stress Disorder (PTSD). Survivors had more than a four-fold risk of PTSD compared to siblings (OR=4.14, 95%CI: 2.08-8.25). Controlling for demographic and treatment variables, increased risk of PTSD was associated with educational level of high school or less (OR=1.51, 95% CI=1.16-1.98), being unmarried (OR=1.99, 95% CI=1.58-2.50), annual income less than $20,000 (OR=1.63, 95% CI=1.21-2.20), and being unemployed (OR=2.01, 95% CI=1.62-2.51). Intensive treatment was also associated with increased risk of full PTSD (OR=1.36, 95% CI 1.06 -1.74).
Posttraumatic stress disorder is reported significantly more often by childhood cancer survivors than by sibling controls. Although most survivors are apparently doing well, a subset report significant impairment that may warrant targeted intervention.

Although sex differences in anxiety sensitivity or the specific tendency to fear anxiety-related sensations have been reported in adults with clinical pain, there is a dearth of relevant research among children. This study examined sex differences in anxiety sensitivity across unselected samples of 187 children with chronic pain (71.7% girls; mean age = 14.5) and 202 non-clinical children (52% girls; mean age = 13.6). Girls in the chronic pain and non-clinical samples reported elevated anxiety sensitivity relative to boys irrespective of clinical status. Girls with chronic pain also reported heightened fears of the physical consequences of anxiety compared to non-clinical girls but there were no such differences for psychological or social concerns. Among boys, anxiety sensitivity did not differ between the chronic pain and non-clinical groups. Future longitudinal research may examine whether specific fears of anxiety-related somatic sensations constitutes a sex-based vulnerability factor in the development of chronic pain.
