OBJECTIVE

A gluten-free camp allows children with celiac disease (CD) to enjoy a camp experience without concern and preoccupation with foods they eat or the stigma of their underlying disease. The objective of this study was to evaluate the impact of gluten-free camp on quality-of-life indicators for children and adolescents with CD.

METHODS

Children aged 7 to 17 years with CD were administered a 14-question survey at the beginning and the end of a 7-day gluten-free camp. Surveys used a Likert scale to examine general well-being, emotional outlook, and self-perception for the week before each survey. Differences between the time points were compared. Data were analyzed by paired t test.

RESULTS

Of the 104 campers who attended camp, 77 (21 male) completed the survey at both time points. Most (70%) had been on a glutenfree diet (GFD) for <4 years. All seemed to benefit from camp, no longer feeling different from other kids or feeling frustrated with a restricted diet. A more beneficial impact was found for campers who were on a GFD for <4 years. Overall, campers reported an improvement in 11 of 14 questions, statistically significant (P <.05) for 8 of those 11 questions. Improvement was observed in each of the 3 categories of questions: well-being, self-perception, and emotional outlook.

CONCLUSIONS

Children who had CD and attended a week-long glutenfree camp demonstrated improvement in well-being, self-perception, and emotional outlook. The positive effects of camp were more apparent among campers who had been on a GFD for <4 years compared with those who had been on a GFD for ≥4 years, suggesting an adaptation to CD with time. A gluten-free camp that provides an environment of unrestricted foods can at least temporarily alleviate stress and anxiety around food and social interactions. Durability of these observations on return to daily life requires additional study.

AIM: To assess attitudes and trends regarding the use of high-dose infliximab among pediatric gastroenterologists for treatment of pediatric ulcerative colitis (UC).

METHODS: A 19-item survey was distributed to subscribers of the pediatric gastroenterology (PEDSGI) listserv. Responses were submitted anonymously and results compiled in a secure website.

RESULTS: A total of 113 subscribers (88% based in the United States) responded (101 pediatric gastroenterology attendings and 12 pediatric gastroenterology fellows). There were 46% in academic medical institutions and 39% in hospital-based practices. The majority (91%) were treating >10 patients with UC; 13% were treating >100 patients with UC; 91% had prescribed infliximab (IFX) 5 mg/kg for UC; 72% had prescribed IFX 10 mg/kg for UC. Using a 5-point Likert scale, factors that influenced the decision not to increase IFX dosing in patients with UC included: “improvement on initial dose of IFX” (mean: 3.88) and “decision to move to colectomy” (3.69). Lowest mean Likert scores were: “lack of guidelines or literature regarding increased IFX dosing” (1.96) and “insurance authorization or other insurance issues” (2.34). “Insurance authorization or other insurance issues” was identified by 39% as at least somewhat of a factor (Likert score ≥ 3) in their decision not to increase the IFX dose. IFX 10 mg/kg was more commonly used for the treatment of pediatric UC among responders based in the United States (75/100) compared to non-United States responders (6/13, P = 0.047). Induction of remission was reported by 78% of all responders and 81% reported maintenance of remission with IFX 10 mg/kg. One responder reported one death with IFX 10 mg/kg.

CONCLUSION: IFX 10 mg/kg is more commonly used in the United States to treat pediatric UC. Efficacy and safety data are required to avoid insurance barriers for its use.

Background

Childhood overweight has become a serious health problem among children and adolescents in the United States. No previous study, to our knowledge, has analyzed the effect of body mass index (BMI) on range of motion and carrying angle of the elbow joint in a healthy pediatric population. The primary objective of this study was to determine the effect of BMI on orthopedic parameters of the elbow joint, including range of motion, flexion, extension, and carrying angle.

Study Participants and Methods

Healthy children age 2 to 18 years (mean 12.0 ± 3.9 years) were recruited at an urban pediatric orthopedic clinic as pediatric orthopedic patients or as the siblings or friends of patients. Measures of range of motion (flexion and extension) and carrying angle of 226 elbows and of BMI from 113 study participants were analyzed.

Results

BMI was negatively correlated with right and left elbow range of motion (r = −0.54, P <0.01; r = −0.43, P <0.01) and right and left elbow flexion (r = −0.59, P <0.01; r = −0.50, P <0.01). BMI had a positive correlation with right elbow extension (r = 0.20, P = 0.04). BMI did not correlate with left elbow extension or right or left carrying angle. After adjustment for age, sex, and ethnic group, BMI was associated with right (P <0.01) and left (P <0.01) elbow range of motion.

Conclusions

These data demonstrate that increased BMI in children is negatively correlated with range of motion of the elbow joint. Further studies are needed to evaluate the consequences of impaired range of motion associated with overweight on activity levels and energy expenditure in growing children and adolescents.

Background

Treatment of ulcerative proctitis has not been well studied in pediatric populations. We conducted an open-label trial to evaluate the clinical efficacy of a mesalamine suppository (500 mg) to treat pediatric patients with mild to moderate ulcerative proctitis.

Methods

Pediatric patients (5–17 years of age) with ulcerative proctitis were enrolled for baseline evaluations, including a flexible sigmoidoscopic (or colonoscopic) assessment with biopsies performed at study entry. Eligible patients were started on mesalamine suppositories (500 mg) at bedtime. Two follow-up visits were scheduled after 3 and 6 weeks of treatment. The dose could be increased to 500 mg twice daily at the week 3 follow-up visit if deemed appropriate by the investigator based on the Disease Activity Index (DAI) assessment. The primary outcome measure was a DAI derived from a composite score of stool frequency, urgency of defecation, rectal bleeding, and general well-being.

Results

Forty-nine patients were included in the intent-to-treat analysis. The mean DAI value decreased from 5.5 at baseline to 1.6 and 1.5 at weeks 3 and 6, respectively (P < 0.0001). Only 4 patients had their dose increased to 500 mg twice daily at week 3. Forty-one patients experienced at least one adverse event, most of which were deemed mild and unrelated to study therapy. The most common treatment-emergent adverse events were gastrointestinal (n = 30, 61.2%).

Conclusions

This study showed that a daily bedtime dose of a 500 mg mesalamine suppository is safe and efficacious in children with ulcerative proctitis.

Objectives

We examined the use of complementary and alternative medicine (CAM) at 3 US pediatric medical centers, comparing a group of children with inflammatory bowel disease (IBD) with children presenting with chronic constipation.

Materials and Methods

Surveys were administered by postal mail and at pediatric IBD centers in San Francisco, Houston, and Atlanta from 2001 to 2003. A comparison group consisting of pediatric patients with chronic constipation also was surveyed. Data were analyzed by t tests and by exact tests of contingency tables.

Results

In all, 236 surveys were collected from the IBD group; 126 surveys were collected from the chronic constipation comparison group. CAM therapies were used by 50% in the IBD group and 23% in the chronic constipation group. The overall regional breakdown of CAM use in IBD revealed no differences, although the types of CAM therapy used varied by site. The most commonly used CAM therapies in the IBD group were spiritual interventions (25%) and nutritional supplements (25%). Positive predictors for CAM use in IBD include the patient's self-reported overall health, an increase in the number of side effects associated with allopathic medications, white ethnicity, and parental education beyond high school.

Conclusions

This is the first US study to characterize CAM use in pediatric patients with IBD with another chronic gastrointestinal disorder. CAM use was twice as common with the IBD group compared with the chronic constipation group. Regional variations exist with the types of CAM therapy used. Practitioners should know that half of their pediatric patients with IBD may be using CAM in conjunction with or as an alternative to other treatments and that certain predictors can help identify those using CAM therapies.

Background

Few studies have reported on the surgical outcomes of colectomy in pediatric patients with ulcerative colitis (UC).

Patients and Methods

We conducted a retrospective chart review of all pediatric patients diagnosed with UC who underwent colectomy at UCSF between 1980 and 2005 to identify early (within 30 days) and later complications of surgery.

Results

Complete medical records were available for 31 patients [12.4 ± 3.3 (range 6–19) years] with UC who underwent colectomy at UCSF Children’s Hospital. Total colectomy with ileal pouch anal anastomosis (IPAA) was performed in 21 of the 31 patients (12 without diverting ileostomy). Five of the 31 patients had an initial colectomy with IPAA and J-pouch performed later; 4 had an initial subtotal colectomy for urgent indications. Only one of 31 had IPAA with S-pouch. The median number of early postoperative complications was 1.0; 4 required additional surgery to treat complications. The most common early complications were small intestinal obstruction in 6 (19%) and wound infection in 4 (13%). Preoperative medications included corticosteroids in 25 (81%), 6-mercaptopurine/azathioprine in 10 (32%), and 5-aminosalicylates in 19 (61%). Medication exposure was not related to postoperative complications. Late complications included pouchitis in 12 (39%), anastomotic, anal, or rectal strictures in 5 (16%), and fistulas in 5 (16%); 1 (3%) was subsequently diagnosed as having Crohn disease.

Conclusions

Postcolectomy morbidity is common among pediatric patients with UC. Preoperative medications were not associated with postoperative complications. Investigations to determine preoperative factors affecting surgical outcomes and long-term satisfaction following this surgery in a large pediatric cohort are needed.

Background & Aims

Dental erosion is a complication of gastroesophageal reflux (GER) in adults; in children, it is not clear if GER has a role in dental pathologic conditions. Dietary intake, oral hygiene, high bacterial load, and decreased salivary flow might contribute independently to GER development or dental erosion, but their potential involvement in dental erosion from GER is not understood. We investigated the prevalence of dental erosion among children with and without GER symptoms, and whether salivary flow rate or bacterial load contribute to location-specific dental erosion.

Methods

We performed a cross-sectional study of 59 children (ages 9–17 y) with symptoms of GER and 20 asymptomatic children (controls); all completed a questionnaire on dietary exposure. Permanent teeth were examined for erosion into dentin, erosion locations, and affected surfaces. The dentist was not aware of GER status, nor was the gastroenterologist aware of dental status. Stimulated salivary flow was measured and salivary bacterial load was calculated for total bacteria, Streptococcus mutans and Lactobacilli.

Results

Controlling for age, dietary intake, and oral hygiene, there was no association between GER symptoms and dental erosion, by tooth location or affected surface. Salivary flow did not correlate with GER symptoms or erosion. Erosion location and surface were independent of total bacteria and levels of Streptococcus mutans and Lactobacilli.

Conclusions

Location-specific dental erosion is not associated with GER, salivary flow, or bacterial load. Prospective studies are required to determine the pathogenesis of GER-associated dental erosion and the relationship between dental caries to GER and dental erosion.

Purpose

To examine the feasibility and efficacy of a theory-driven and family-based program delivered online to promote healthy lifestyles and weights in Chinese American adolescents.

Methods

A randomized controlled study of a Web-based intervention was developed and conducted in 54 Chinese American adolescents (ages, 12–15 years) and their families. Data on anthropometry, blood pressure, dietary intake, physical activity, and knowledge and self-efficacy regarding physical activity and nutrition were collected at baseline and 2, 6, and 8 months after the baseline assessment. Data were analyzed using linear mixed modeling.

Results

The intervention resulted in significant declines in waist-to-hip ratio and diastolic blood pressure and increases in vegetable and fruit intake, level of physical activity, and knowledge about physical activity and nutrition.

Conclusions

This Web-based behavior program for Chinese American adolescents and their families appears feasible and effective in the short term. Longer term effects remain to be determined. This type of program can be adapted for other minority ethnic groups who are at high risk for overweight and obesity and have limited access to programs that promote healthy lifestyles.

Twenty percent of inflammatory bowel disease (IBD) patients present in the pediatric years, with recent reports suggesting a rising incidence in the pediatric age group. This highlights the need for both pediatric and adult gastroenterologists to better understand issues related to the process of transition from pediatric to adult care. Research from other disciplines outside of IBD provide evidence that the transition period can be associated with poorer health outcomes and that a structured transition program may improve patient compliance and disease control. Recent data from the IBD literature support a need for transition clinics. The ideal model of a transition program has not been established. Controlled trials are not available to measure the impact of a structured transition program on clinically relevant endpoints such as disease control and hospital admissions. As local resources and availability of staffing and funding are highly variable, we have summarized some practical guidelines for the adult and pediatric gastroenterologist that can be used as an aid to help adolescents through the transition process even without the support of an established transition clinic.

Background

Awareness of federal nutrition programs and use of the nutrition facts label are associated with reduced risk for obesity and increased intake of fruits and vegetables. Relationships between nutrition programs, use of food labels and risk for overweight and obesity have rarely been evaluated in adolescents.

Methods

Using the National Health and Nutrition Examination Survey from 2005–6, we evaluated the frequency of nutrition awareness of USDA and CDC nutrition programs and use of food labels in adolescents. Risk for overweight (BMI ≥ 85-94th percentile) and obesity (BMI ≥ 95th percentile) was assessed in relation to nutrition awareness and label reading.

Results

Most adolescents (92.4%) were aware of the Food Guide Pyramid. Fewer (43.5%) were aware of the 5-A-Day Program, and even less (29.3%) were aware of the Dietary Guidelines for Americans. Less than 25% of adolescents decided which foods to purchase by reading material on the nutrition facts label. There were significant racial and ethnic differences in awareness of federal nutrition programs with Mexican-Americans having the lowest levels of awareness of the US Dietary Guidelines for Americans and the Food Guide Pyramid in comparison with other groups. Non-Hispanic whites had higher and African-American adolescents had lower frequencies of reading fat information on the nutrition label in comparison to Mexican-American and other Hispanics. Awareness of other nutrition programs or of other information on the nutrition facts label was not associated with increased or decreased risk for overweight or obesity.

Conclusions

Use of the nutrition facts panel information is low among US adolescents. Additionally, less than half of adolescents are aware of federal nutrition programs including the Dietary Guidelines for Americans. Future studies should evaluate avenues to make nutrition information more accessible to young Americans.

Background and Aims

Few epidemiological investigations characterize inflammatory bowel disease (IBD) in non-Caucasian children. Our study compared IBD characteristics between African-Americans and non-African-Americans enrolled in a multi-center pediatric IBD registry with endoscopic- and pathology-based diagnosis.

Methods

The study retrieved data entered from January 2000–October 2003 on children 1 to 17 years old, inclusive, followed by a consortium of academic and community U.S. pediatric gastroenterology practices. Analyses examined racial/ethnic differences by comparing the proportions of African-Americans and non-African-Americans in: each diagnostic disease classification (any IBD, Crohn's disease, ulcerative colitis, indeterminate colitis); age group (<6y, 6–12y or >12y) at diagnosis or symptom onset; presence of extraintestinal manifestations, Z-scores for height and weight, immunomodulatory therapy, anatomic disease location and abnormal hemoglobin, albumin or sedimentation rate at diagnosis.

Results

1,406 patients had complete data, 138 (10%) of whom were African-American. African-Americans more often: were >12y of age at diagnosis (52% vs. 37%, OR 1.82, 95% CI 1.28–2.59) and symptom onset (46% vs. 30%, OR 1.99, 95% CI 1.40–2.84); had Crohn's disease (78% vs. 59%, OR 2.36, 95% CI 1.56–3.58); had low hemoglobin at diagnosis (39% vs. 17%, OR 3.15, 95% CI 1.92–5.17).

Conclusions

IBD in African-American children and adolescents presents more commonly with CD and at older ages compared to non-African-Americans. Racial/ethnic differences in the epidemiology of IBD, particularly CD, among American youths require further investigation.

Objectives

A multicenter, double-blind study was conducted to evaluate the safety, efficacy and pharmacokinetics of balsalazide in pediatric patients with mild-to-moderate UC.

Methods

Sixty-eight patients, 5 to 17 years of age, with mild-to-moderate active UC based on the modified Sutherland UC activity index (MUCAI), were randomized to receive oral balsalazide 2.25 or 6.75 g/day for 8 weeks. The primary endpoint was clinical improvement (reduction of the MUCAI score by ≥3 points from baseline). Clinical remission (MUCAI score of 0 or 1 for stool frequency) and histological improvement after 8 weeks were also assessed. Pharmacokinetic parameters for balsalazide, 5-aminosalicylic acid, and N-acetyl-5-aminosalicylic acid were determined at 2 weeks. Adverse events and laboratory changes were monitored throughout the study.

Results

Clinical improvement was achieved by 45% and 37% of patients and clinical remission by 12% and 9% of patients receiving 6.75 and 2.25 g/day, respectively. Improvement in histologic grade was achieved by 8 of 16 (50%) and 3 of 10 (30%) patients receiving 6.75 and 2.25 g/day, respectively. No significant differences were seen in efficacy. Pharmacokinetics in 12 patients were characterized by large inter-subject variability and low systemic exposure. Adverse events were similar between the treatment groups, the most common being headache and abdominal pain. No clinically significant changes were observed in laboratory values, including those indicative of hepatic or renal toxicity.

Conclusions

Balsalazide is well-tolerated and improves the signs and symptoms of mild-to-moderate active UC in pediatric patients 5 to 17 years of age.

Background

The development of disease complications is poorly characterized in pediatric patients with Crohn’s disease (CD).

Methods

We retrospectively determined the cumulative incidence of stricturing and penetrating complications of CD prior to first surgery utilizing data from 989 consecutively enrolled CD patients (age 0–17 years at diagnosis) collected between January 2000 and November 2003 and stored in the Pediatric IBD Consortium Registry.

Results

Mean age at diagnosis was 11.5 ± 3.8 (standard deviation) years. Median follow-up time was 2.8 years. Prior to first surgery, the cumulative incidence of stricturing or penetrating complications was 27% at 5 years and 38% at 10 years from the diagnosis of inflammatory bowel disease. The cumulative incidence of complicated disease was lowest in isolated colonic disease (P = 0.009). Penetrating complications that followed stricturing complications prior to first surgery occurred within 2 years of stricturing complications (cumulative incidence was 13% at 2 years from diagnosis of stricturing disease). Stricturing complications that followed penetrating complications prior to first surgery occurred within 8 years of penetrating complications (cumulative incidence was 26% at 8 years from diagnosis of penetrating complications).

Conclusions

Strictures, abscesses, and fistulas are common in pediatric CD. Earlier aggressive management may be indicated. Prospective study is required to identify genetic and serologic markers that predict a patient’s risk for the development of complicated disease and to determine optimal treatment regimens.

Abnormal cytokine production by T-helper 1 (Th1)/T-helper 2 (Th2) lymphocytes has been implicated in the pathogenesis of inflammatory bowel disease (IBD). Few studies have examined Th1/Th2 cytokine status in pediatric IBD patients, and results have been inconsistent. We used flow cytometric detection of intra-cellular IFN-γ/IL-4 cytokine production to investigate CD4+, Th1, and Th2 cells in the peripheral blood of children with untreated, newly diagnosed Crohn’s disease (CD) (n = 23) and matched healthy controls (n = 49). Th1 cytokine levels were lower in CD patients compared with controls (p = 0.006) and strongly correlated with levels of albumin and hematocrit (r = 0.51, p = 0.007 and r = 0.35, p = 0.052, respectively). An age-dependent increase in Th1 cells was observed (p < 0.0005); however, no correlation was found between age, clinical end points, %CD4+, or Th2 cell numbers. In conclusion, the Th1 cytokine levels in blood are lower in early onset CD patients than in healthy children and are directly associated with disease-related clinical parameters. In future studies of pediatric IBD patients, it will be critical to consider the effect of age and disease progression on cytokine status in intestinal mucosa and peripheral blood.

The objective of this study was to evaluate the relationship between maternal nutrition knowledge and maternal socio-demographics including participation in the Special Supplemental Women, Infants and Children’s (WIC) Program. A cross-sectional study of new mothers at two San Francisco hospitals was conducted using some of the American Academy of Pediatrics’ guidelines in a structured questionnaire to assess maternal nutritional knowledge. Maternal nutritional attitudes towards product nutrient labels were also assessed in a questionnaire format. Logistic regression models were used to evaluate the odds of having high maternal nutrition knowledge and of infrequently reading nutrition labels. In multivariate logistic regression models, higher maternal nutrition knowledge (defined as answering all four nutrition questions correctly) was associated with higher income levels defined as ≥$25 000/year, odds ratio (OR) 10.03 95% confidence interval (CI) (1.51–66.74), and in linear models, higher nutritional knowledge was associated with having more children (P < 0.01), a higher income (P = 0.01) and not being a WIC participant (P < 0.01). Mothers with higher incomes were also more likely to read product nutritional labels OR 4.24, 95% CI (1.24–14.51), compared with mothers with lower incomes as were mothers with higher education levels OR 3.32, 95% CI (1.28–8.63). In San Francisco, lower income mothers are at greatest risk for low maternal nutrition knowledge and not reading product nutritional labels. Higher household income was independently associated with increased maternal nutrition knowledge and likelihood of reading nutritional labels. More comprehensive interventions need to target low-income mothers including current WIC participants to help close the nutritional advantages gap conferred by income and education.

Background

The small bowel follow-through (SBFT) is a non-invasive imaging modality for evaluating terminal ileum (TI) inflammation. The accuracy of this modality in pediatric patients is not well established.

Methods

We retrospectively determined the sensitivity and specificity of SBFT for detecting TI inflammation diagnosed on histology in 93 pediatric patients followed in a single institution.

Results

The mean age at the first study was 12.9 years [range: 1.1-20.9 years]. 45% were female. Twenty-five patients (27%) had abnormal TI's on SBFT. Seventeen patients (18%) had TI inflammation diagnosed by biopsy. The sensitivity of SBFT was 59% and the specificity was 80% for detecting TI inflammation diagnosed on histology. Sensitivity and specificity did not change by demographic factors, final diagnoses, presenting symptoms, or laboratory parameters reflecting the presence of intestinal inflammation.

Conclusions

The sensitivity and specificity of SBFT in pediatric patients were poor and did not vary with demographic factors, final diagnoses, presenting symptoms, or laboratory parameters. Prospective longitudinal studies comparing various imaging modalities (SBFT, magnetic resonance (MR) enterography, and capsule endoscopy) are required to determine which is the most effective tool for evaluating pediatric patients for TI inflammation.

Background

Interventions to teach children healthy and effective coping skills could help reduce their risk for overweight. However, few studies have examined whether an intervention that teaches coping strategies in weight management can influence children’s coping behavior and psychosocial well-being.

Objective

To examine the efficacy of an interactive, child-centered, and family-based program in promoting effective coping, behavioral health, and quality of life in Chinese American children.

Method

A randomized, controlled study of behavioral intervention in 67 Chinese American children (ages 8–10 years, normal weight and overweight) and their families. At baseline and 2, 6, and 8 months after baseline, children had anthropometric measurements and completed questionnaires related to coping skills and quality of life, and parents completed the Child Behavior Checklist.

Results

Children in the intervention group reported using more active coping strategies and having a higher quality of life in the physical and emotional health domains than did children in the control group during the 8-month study. Children’s behavioral problems did not differ between the intervention and control groups. Changes in coping and psychosocial well-being were not related to change in body mass index (BMI) in the entire group, except increased BMI is associated with decreased emotional quality of life.

Discussion

This culturally appropriate behavioral intervention was effective in promoting healthy coping and improving quality of life in Chinese American children. Its utility for both optimal weight and overweight children suggests potential application of the intervention in a broad range of populations.

Objective

A systematic review was conducted to assess the possible association between omega-3 polyunsaturated fatty acid (PUFA) supplementation and intake in the perinatal period and the risk of maternal perinatal depression.

Methods

Two PubMed searches and a BIOSIS Preview, a Web of Science and a PsychInfo search were conducted with the search terms ‘DHA, pregnancy and depression’ and ‘omega-3 fatty acids, pregnancy and depression’.

Results

Ten articles – three longitudinal cohort studies, five randomized controlled trials and two pilot trials– that met selection criteria were reviewed. Six found no association, two found mixed results, and two found a positive association between omega-3 PUFAs and reduced incidence of maternal perinatal depression. The heterogeneity of results can be explained by dissimilar study designs, including differences in study duration, time period of measurement and number of participants, and in varied dosages and types of supplemental PUFAs. Some of the larger studies and those that found a positive effect were more likely to be using higher doses, close to 2 g of docosahexaeonic acid (DHA) + eicosapentaenoic acid (EPA), and began the supplementation earlier in pregnancy.

Conclusions

Future RCTs to investigate the role of PUFA supplementation and risk for maternal perinatal depression should begin supplementation early in pregnancy and use a dosage closer to 2 g of DHA + EPA. Depression should also be measured using a diagnostic interview schedule in addition to a screener.

Objective

To examine the efficacy of an interactive, child-centred and family-based program in promoting healthy weight and healthy lifestyles in Chinese American children.

Design

A randomized controlled study of a culturally sensitive behavioral intervention.

Subjects

Sixty-seven Chinese American children (ages, 8–10 years; normal weight and overweight) and their families.

Measurements

Anthropometry, blood pressure, measures of dietary intake, physical activity, knowledge and self-efficacy regarding physical activity and diet at baseline and 2, 6 and 8 months after baseline assessment.

Results

Linear mixed modeling indicated a significant effect of the intervention in decreasing body mass index, diastolic blood pressure and fat intake while increasing vegetable and fruit intake, actual physical activity and knowledge about physical activity.

Conclusion

This interactive child-centred and family-based behavioral program appears feasible and effective, leading to reduced body mass index and improved overweight-related health behaviors in Chinese American children. This type of program can be adapted for other minority ethnic groups who are at high risk for overweight and obesity and have limited access to programs that promote healthy lifestyles.

Objective

To extend development of a pediatric inflammatory bowel disease (IBD) health-related quality of life (HRQoL) measure by determining its factor structure and associations of factors with generic HRQoL measures and clinical variables.

Patients and Methods

Cross-sectional survey of children and adolescents ages 8 years to 18 years and their parents attending any of 6 US IBD centers, recruited from either existing registry of age-eligible subjects or visits to participating centers. The survey included generic (Pediatric Quality of Life Inventory) and IBD-specific (Impact Questionnaire) quality of life measures, disease activity, and other clinical indicators. We carried out factor analysis of Impact responses, comparing resulting factors with results on the generic HRQoL and the clinical measures.

Results

We included 220 subjects (161 with Crohn disease and 59 with ulcerative colitis). Initial confirmatory factor analysis did not support the 6 proposed Impact domains. Exploratory factor analysis indicated 4 factors with good to excellent reliability for IBD responses: general well-being and symptoms, emotional functioning, social interactions, and body image. Two items did not load well on any factor. The 4 factors correlated well with the Pediatric Quality of Life Inventory and subscales. Children with higher disease activity scores and other indicators of clinical activity reported lower HRQoL.

Conclusions

This study provides further characteristics of a HRQoL measure specific to pediatric IBD and indicates ways to score the measure based on the resulting factor structure. The measure correlates appropriately with generic HRQoL measures and clinical severity indicators.

Background

Latino children are at increased risk for mirconutrient deficiencies and problems of overweight and obesity. Exposures in pregnancy and early postpartum may impact future growth trajectories.

Objectives

To evaluate the relationship between prenatal and postnatal maternal depressive symptoms experienced in pregnancy and infant growth from birth to 2 years of age in a cohort of Latino infants.

Methods

We recruited pregnant Latina mothers at two San Francisco hospitals and followed their healthy infants to 24 months of age. At 6, 12 and 24 months of age, infants were weighed and measured. Maternal depressive symptoms were assessed prenatally and at 4-6 weeks postpartum. Women who had high depressive symptoms at both time periods were defined as having chronic depression. Logistic mixed models were applied to compare growth curves and risk for overweight and underweight based on exposure to maternal depression.

Results

We followed 181 infants to 24 months. At 12 and 24 months, respectively, 27.4% and 40.5% were overweight, and 5.6% and 2.2% were underweight. Exposure to chronic maternal depression was associated with underweight (OR = 12.12, 95%CI 1.86-78.78) and with reduced weight gain in the first 2 years of life (Coef = -0.48, 95% CI -0.94—0.01) compared with unexposed infants or infants exposed to episodic depression (depression at one time point). Exposure to chronic depression was also associated with reduced risk for overweight in the first 2 years of life (OR 0.28, 95%CI 0.03-0.92).

Conclusions

Exposure to chronic maternal depression in the pre- and postnatal period was associated with reduced weight gain in the first two years of life and greater risk for failure to thrive, in comparison with unexposed infants or those exposed episodically. The infants of mothers with chronic depression may need additional nutritional monitoring and intervention.
