Objectives To characterize, during a 2-year period, the proportion of youth with type 2 diabetes (T2D) enrolled in the Treatment Options for Type 2 Diabetes in Adolescents and Youth study that reported ever at least trying smoking cigarettes and/or drinking alcohol. Study design Longitudinal data were examined for participants with T2D ages 10-18 years at baseline. Youth psychosocial, parent/family, environmental, and biological correlates of trying health risk behaviors were tested via cross-sectional multivariate models at each time point. Longitudinal models were explored for selected factors. Results Data were obtained from the Treatment Options for Type 2 Diabetes in Adolescents and Youth study's ethnically diverse participants at baseline (N = 644), 6-month (N = 616), and 24-month (N = 543) assessments. The percentage of youth ever trying only smoking remained stable at 4%; only drinking alcohol increased from 17% to 26%, and both smoking and drinking increased from 10% to 18% during the 2-year period. Factors related to trying health risk behaviors were older age, male sex, non-Hispanic white race-ethnicity, lower grades, more depressive symptoms, and stressful life events. Depressive symptoms, stressful life events, and body mass index Z-score (the latter with smoking only) were related to engagement in health risk behaviors over time. Conclusions Youth with T2D who are already at risk for health complications and who reported engaging in activities that further increase the likelihood of life-threatening morbidities were characterized. Although most correlates of trying these risk behaviors are nonmodifiable, intervention efforts may need to focus on potentially modifiable factors, such as depressive symptoms and lower grades.

To determine short- and long-term effects of the Bright Bodies Weight Management Program on obese adolescents and to further observe if a diet or nondiet approach is more successful.Twenty-five obese adolescents completed a 1-year, comprehensive weight-management program and returned for a 2-year follow-up. Adolescents were 11 to 16 years old (17 female, eight male) with mixed ethnic backgrounds. Although the program emphasizes a nondiet approach, eight children requested a structured meal plan (diet approach), while 17 were taught to make better food choices (nondiet approach). Body mass index (BMI) z score, body fat percent, and self-concept were measured at 0, 1, and 2 years. Outcomes were analyzed for the entire group and by diet method groups.Changes in outcome variables were evaluated using covariance pattern models for repeated measures.At 1 year, the entire group (N=25) demonstrated a decrease in BMI z score (P.001) and body fat percent (P.001), while self-concept scores increased (P.001). At 2 years, the decrease in BMI z score was still significant (P =.004) and body fat percent and self-concept scores remained improved, although not significant compared to baseline (P =.15 and P =.10, respectively). When comparing dietary approaches, the dieting group (n=8) tended to show favorable results short-term for BMI z score at year 1 (P =.11), but by year 2, the nondieting group (n=17) further improved BMI z score (P =.006), while the dieting group reverted toward baseline.The Bright Bodies Weight Management Program was successful at decreasing BMI z scores both short and long term. In a separate analysis, dieting showed more superior short-term results, but a nondiet approach demonstrated improved long-term results.
