RESUMO

OBJECTIVE: To examine the cross-sectional associations between diabetes distress, BMI (zBMI; BMI z-score), objectively measured mean daily blood glucose readings and insulin boluses administered, and A1C in adolescents with type 1 diabetes (T1D) using insulin pumps. METHODS: T1D self-management behaviour data were downloaded from adolescents' (N = 79) devices and mean daily frequency of blood glucose readings and insulin boluses were calculated. Diabetes distress was measured (Problem Areas in Diabetes-Teen questionnaire [PAID-T]), A1C collected, and zBMI calculated from height and weight. Three multiple linear regressions were performed with blood glucose readings, insulin boluses, and A1C as the three dependent variables and covariates (age, T1D duration), zBMI, diabetes distress, and the diabetes distress x zBMI interaction as independent variables. RESULTS: Participants (55.7% female) were 14.9 ± 1.9 years old with T1D for 6.6 ± 3.4 years. zBMI moderated the relationship between diabetes distress and mean daily insulin boluses administered (b = -0.02, p = 0.02); those with higher zBMI and higher diabetes distress administered fewer daily insulin boluses. zBMI was not a moderator of the association between diabetes distress and blood glucose readings (b = -0.01, p = 0.29) or A1C (b = 0.002, p = 0.81). CONCLUSIONS: Using objective behavioural data is useful for identifying how adolescent diabetes distress and zBMI affect daily bolusing behaviour amongst adolescent insulin pump users. Although distinct interventions exist to improve T1D self-management or diabetes distress, none addresses them together while considering zBMI. Decreasing diabetes distress could be especially important for youth with high zBMI.

RESUMO

OBJECTIVE: Increased rates of pediatric obesity extend into early childhood. There have been increasing calls for intervention programs specifically designed to address obesity in preschool-age youth. A review of the literature is critical to guide intervention and future research. The objective of this study was to conduct a meta-analysis of randomized, controlled trials examining the efficacy of lifestyle modification interventions to address overweight and obesity in preschool-age children. METHOD: Six electronic databases were searched for articles through December 8, 2020. After screening articles for inclusion criteria, 14 articles with 12 randomized, controlled trials (41 effect sizes, 2,525 participants) were included in this meta-analysis. Weighted-standardized mean differences for body mass index-related variables were calculated using random-effects models to estimate effect sizes. Risk of bias assessment was conducted. RESULTS: There was a statistically significant impact of the interventions on child weight outcomes. Cohen's d was .32 (95% CI [.09, .55]). The quality of evidence was assigned a "low" GRADE rating. CONCLUSIONS: Lifestyle modification interventions for overweight and obesity in preschool-age children produce small but significant changes in child weight status. However, few new trials have been published in the last 5 years and the quality of evidence in this area is low, limiting confidence in the estimates and the power to examine potential moderator effects. Additional quality, randomized, control trials that report study information consistent with consort guidelines, use intent-to-treatment procedures, assess and report health behaviors and treatment adherence to explore mechanisms of change, and examine sustained effects of interventions are needed.

RESUMO

PURPOSE OF REVIEW: Understanding barriers to self-management behaviors and glycemic stability may inform specific needs for behavior change in adolescents and young adults with type 1 diabetes (T1D). The current review aims to systematically synthesize the literature on the relationships between executive functioning, self-management, and A1C in adolescents and young adults with T1D. Fifteen studies were retained in the current review. Study quality assessment for the majority of the studies were "Fair" or "Good." RECENT FINDINGS: This review highlights several advances in research design, including use of longitudinal designs, data from multiple informants, and use of objective measures. Adolescents and young adults reported that more executive functioning weaknesses were related to decreased self-management behaviors and higher A1C. The current review demonstrated that self-perceived executive functioning weaknesses negatively impact self-management behaviors and A1C. Future research is needed to determine the utility of objective measures in assessing the relationships between executive functioning, T1D self-management, and A1C.

RESUMO

OBJECTIVE: Youth with poorer inhibitory control are more likely to experience internalizing and externalizing problems, placing them at risk for poorer psychological, academic, and social functioning. Modifying inhibitory control is challenging; therefore, research is needed to identify alternative targets to reduce internalizing and externalizing problems in youth. Sleep/wake patterns may serve as alternative targets, given their relationships with poorer inhibitory control and greater internalizing and externalizing problems. This study examines the mediating role of sleep/wake patterns in the relationships between youth inhibitory control and internalizing and externalizing problems. METHOD: One hundred fifty-five adolescent (ages 12-15 years) and parent dyads completed the Behavioral Rating Inventory of Executive Function, Pediatric Symptom Checklist, and Adolescent Sleep-Wake Scale, short version. Bootstrapped mediations examined indirect relationships between inhibitory control and internalizing and externalizing through sleep/wake patterns. RESULTS: Analyses revealed that problematic sleep/wake patterns partially mediated the relationship between poorer inhibitory control and greater internalizing, explaining 19% of the variance in internalizing problems. In addition, problematic sleep/wake patterns partially mediated the relationship between poorer inhibitory control and greater externalizing, explaining 58% of the variance in externalizing problems. CONCLUSION: The results suggest that sleep/wake patterns may be a mechanism through which deficits in inhibitory control increase youth risk for internalizing and externalizing problems. Because sleep/wake patterns are frequently modified through adoption of health behaviors conducive to good sleep, assessing for problematic patterns in adolescents who present with internalizing and externalizing problems may offer providers a relatively modifiable target to reduce the emotional and behavioral problems of youth with poorer inhibitory control abilities.
