- The current study examined the utility of a new self-report questionnaire, the Illness Identity Questionnaire (IIQ), which assesses the concept of illness identity, or the degree to which type 1 diabetes is integrated into one's identity. Four illness identity dimensions (engulfment, rejection, acceptance, and enrichment) were validated in adolescents and emerging adults with type 1 diabetes. Associations with psychological and diabetes-specific functioning were assessed.

- The increasing importance of peers in adolescence and emerging adulthood has been widely acknowledged. However, longitudinal research linking the peer context to diabetes management and outcomes is scarce. The present longitudinal study in a large sample of youths with type 1 diabetes related both positive and negative peer variables to diabetes outcomes over a time interval of 1 year.Our sample consisted of 467 adolescents (14-17 years of age) and emerging adults (18-25 years of age) with type 1 diabetes who participated in a two-wave longitudinal study. Questionnaires tapped into peer support, extreme peer orientation, parental responsiveness, diabetes-related distress, and treatment adherence. HbA1c values were obtained from the treating physicians of patients. Cross-lagged analysis from a structural equation modeling approach was performed to assess the directionality of effects.Peer support negatively predicted diabetes-related distress over time. Extreme peer orientation positively predicted treatment distress over time. Parental responsiveness negatively predicted food distress over time. Treatment adherence negatively predicted extreme peer orientation, treatment distress, and HbA1c values over time. For emerging adults specifically, there was a reciprocal relationship between HbA1c values and extreme peer orientation, because they positively predicted each other.This study highlights the importance of peers in predicting the functioning of youths with type 1 diabetes. Additionally, treatment adherence at baseline was found to negatively predict extreme peer orientation, treatment distress, and worse glycemic control over time. In sum, the current study underscores the importance of the peer context for adolescents and emerging adults with type 1 diabetes.

- OBJECTIVE: We examined the independent relationships between objectively measured physical activity and insulin resistance in Portuguese children. RESEARCH DESIGN AND METHODS: This is a school-based, cross-sectional study in 147 randomly selected girls (aged 9.8 +/- 0.3 years; 27.8 +/- 9.3% body fat) and 161 boys (aged 9.8 +/- 0.3 years; 22.0 +/- 9.2% body fat). Physical activity was assessed by the Actigraph accelerometer for 4 days and summarized as time spent sedentary (accelerometer counts <500/min), in light-intensity (accelerometer counts 500-2,000/min), and in moderate- and vigorous-intensity activity (accelerometer counts >2,001/min). We measured total and central fat mass by dual-energy X-ray absorptiometry. Insulin resistance was expressed as the homeostasis model assessment score. RESULTS: Time (min/day) spent sedentary was significantly and positively associated with insulin resistance (beta-coefficient = 0.001 [95% CI 0.0002-0.002]; P = 0.013). Time spent in moderate- and vigorous-intensity physical activity (-0.002 [-0.003 to -0.001]; P = 0.0009) and overall physical activity (-0.001 [-0.008 to 0.003]; P < 0.0001) were significantly and inversely associated with insulin resistance. All associations remained statistically significant, although they were attenuated after further adjustments for sex, birth weight, sexual maturity, and total or central fat mass (P < 0.03). CONCLUSIONS: Physical activity is associated with insulin resistance independent of total and central fat mass in children. Our results emphasize the importance of decreasing sedentary behavior and increasing time spent in moderate- and vigorous-intensity activity in children, which may have beneficial effects on metabolic risk factors regardless of the degree of adiposity.
