Improving dietary quality in youth with type 1 diabetes: randomized clinical trial of a family-based behavioral intervention.

ABSTRACT: Diets of children with type 1 diabetes are low in fruits, vegetables, and whole grains, and high in foods of minimal nutritional value, increasing risk for future adverse health outcomes. This 18-month randomized clinical trial tested the effect of a family-based behavioral intervention integrating motivational interviewing, active learning, and applied problem-solving on the primary outcomes of dietary intake and glycemic control among youth with type 1 diabetes.A parallel-group study with equal randomization was conducted at an outpatient, free-standing, multidisciplinary tertiary diabetes center in the United States. Eligible youth were those age 8-16 years with type 1 diabetes diagnosis ?1 year and hemoglobin A1c (HbA1c) ?6.5% and ?10.0%. Participants were 136 parent-youth dyads (treatment n = 66, control n = 70). The intervention consisted of 9 in-clinic sessions delivered to the child and parent; control condition comprised equivalent assessments and number of contacts without dietary advice. Dietary intake was assessed using 3-day diet records at 6 time points across the 18-month study. Dietary outcomes included the Healthy Eating Index-2005 (HEI2005; index measuring conformance to the 2005 United States Dietary Guidelines for Americans) and Whole Plant Food Density (WPFD; number of cup or ounce equivalents per 1000 kcal of whole grains, whole fruit, vegetables, legumes, nuts, and seeds consumed). HbA1c was obtained every 3 months. Overall comparison of outcome variables between intervention and usual care groups was conducted using permutation tests.There was a positive intervention effect across the study duration for HEI2005 (p?=?.015) and WPFD (p?=?.004). At 18 months, HEI2005 was 7.2 greater (mean?±?SE 64.6?±?2.0 versus 57.4?±?1.6), and WPFD was 0.5 greater (2.2?±?0.1 versus 1.7?±?0.1) in the intervention group versus control. There was no difference between groups in HbA1c across the study duration.This behavioral nutrition intervention improved dietary quality among youth with type 1 diabetes, but did not impact glycemic control. Findings indicate the potential utility of incorporating such strategies into clinical care, and suggest that improvement in diet quality can be achieved in families living with this burdensome disease.Clinicaltrials.gov registration number: NCT00999375.

Project description:BACKGROUND:Children who are picky eaters typically demonstrate persistent food refusal and poor diet quality and may be resistant to intervention. OBJECTIVE:This study tested whether pickiness moderated the effect of a nutrition intervention on diet quality in youth with type 1 diabetes, hypothesizing that the intervention effect would be smaller among picky relative to nonpicky eaters. DESIGN:The study was an 18-month randomized clinical trial. PARTICIPANTS:Youth age 8.0 to 16.9 years (n=136) with type 1 diabetes duration ?1 year, receiving care at an outpatient diabetes center in Boston, MA, and a parent, participated from 2010 to 2013. INTERVENTION:The intervention integrated motivational interviewing, active learning, and applied problem solving to increase whole plant food intake. MAIN OUTCOME MEASURES:Whole plant food density (WPFD, cup/oz equivalents per 1,000 kcal target food groups), Healthy Eating Index-2005 (HEI2005, measures conformance to US dietary guidelines), and dietary variety were calculated from 3-day food records completed at six different times. Parents completed the pickiness subscale of the Child Feeding Questionnaire. STATISTICAL ANALYSES PERFORMED:Mean WPFD and HEI2005 were estimated using the population ratio method; standard errors were computed using jackknife variance-covariance estimation. Overall P value comparing groups across visits was derived using the ?2 test. RESULTS:Baseline diet quality was lower in picky than in nonpicky eaters. No intervention effect on pickiness or dietary variety was seen. In stratified analyses, the intervention effect on diet quality was significant for picky eaters only (WPFD P=0.0003; HEI2005 P=0.04). Among picky eaters, diet quality in the treatment group improved, whereas diet quality in the control group remained low. Diet quality of nonpicky eaters in the intervention group changed to a lesser degree. CONCLUSIONS:The intervention resulted in increased diet quality in picky eaters, whereas no intervention effect was seen in nonpicky eaters. Findings suggest that diet quality of picky eaters can be improved without changing their underlying pickiness.

Project description:It is well established that behavioral lifestyle interventions resulting in modest weight reduction in adults can prevent or delay type 2 diabetes mellitus; however in children, successful weight management interventions are rarely found outside of controlled clinical settings. The lack of effective community-based programs is a barrier to reducing obesity prevalence and diabetes risk in children. The objective of our study is to develop and test a group-randomized family-centered community-based type 2 diabetes prevention intervention targeting at-risk children, 9- to 12-years-old.Using participatory methods, the adult-focused YMCA Diabetes Prevention Program was adapted for families, creating a novel lifestyle behavior change program focused on healthy eating, physical activity, and a supportive home environment. The program will be tested in sixty 9- to 12-year-old children at risk of diabetes and sixty parents over 12 consecutive weeks with two intervention formats randomized by location: a face-to-face instructor-led program, or a hybrid program with alternating face-to-face and mobile technology-delivered content. Anthropometric, behavioral, psychosocial and physiological outcomes will be assessed at baseline, post-intervention (12 weeks), and follow-up (24 weeks). Secondary outcomes are participant acceptability, feasibility, and adherence. The RE-AIM framework (reach, efficacy, adoption, implementation, and maintenance) will guide intervention implementation and evaluation. Changes at 12 weeks will be assessed using a paired t-test combining both delivery formats. Exploratory models using linear regression analysis will estimate the magnitude of the difference between the face-to-face and hybrid format. The sample size of 60 children, informed by a previous YMCA intervention in which -4.3 % change in overweight (SE?=?1.1) was observed over 6 months, will give us 80 % power to detect an effect size of this magnitude, assuming a one-sided test at alpha?=?0.05.The proposed study capitalizes on a partnership with the YMCA, a popular and widespread community organization, and uses mobile technologies to extend program reach while potentially reducing burden associated with weekly attendance. The long-term goal is to create a scalable, replicable, and sustainable pediatric "diabesity" prevention program that overcomes existing barriers to the translation of efficacious interventions into effective community programs.ClinicalTrials.gov, NCT02421198 on April 15, 2015.

Project description:BACKGROUND:Parent-child diet quality resemblance is unknown in families of youth with type 1 diabetes, for whom nutrition is central to disease management. OBJECTIVE:Examine diet quality resemblance in families of youth with type 1 diabetes participating in a behavioral nutrition intervention trial and investigate whether treatment assignment or family meal frequency modifies resemblance. DESIGN:This is a secondary data analysis from an 18-month randomized controlled trial conducted August 2010 to May 2013. PARTICIPANTS/SETTING:Parent-youth dyads (N=136, child age=12.3±2.5 years) were recruited from a northeast US diabetes center. MAIN OUTCOME MEASURES:Parent and child Healthy Eating Index-2005 (HEI-2005, reflecting adherence to 2005 Dietary Guidelines for Americans) and whole plant food density (WPFD, reflecting intervention target foods) were calculated from 3-day food records collected every 6 months. STATISTICAL ANALYSIS:Linear random effects models adjusting for demographics and disease characteristics investigated parent-child diet quality resemblance. Separate models examined whether treatment assignment or family meal frequency modified resemblance. Three-way interaction terms examined whether resemblance changed over time by treatment assignment. RESULTS:Time-varying parent and child HEI-2005 and WPFD were positively associated (P<0.001), and there were no interactions with family meals. Parent-child HEI-2005 resemblance was similar across treatment groups; however, parent-child WPFD resemblance was stronger in the intervention (?±standard error [SE]=.30±.06) vs control families (?±SE=.12±.05). Parent-child HEI-2005 resemblance was similar over time by treatment assignment, whereas parent-child WPFD resemblance increased over time for families in the intervention group (three-way interaction term ?±SE=.03±.01). CONCLUSIONS:Parent and youth diet quality were positively correlated in families of youth with type 1 diabetes. Resemblance was stronger in the intervention group for target foods, but not for a general measure of diet quality. The lack of effect modification by family meal frequency suggests that family diet quality resemblance is not contingent on shared meals.

Project description:Youth in war-affected regions are at risk for poor psychological, social, and educational outcomes. Effective interventions are needed to improve mental health, social behavior, and school functioning. This randomized controlled trial tested the effectiveness of a 10-session cognitive-behavioral therapy (CBT)-based group mental health intervention for multisymptomatic war-affected youth (aged 15-24 years) in Sierra Leone.War-affected youth identified by elevated distress and impairment via community screening were randomized (stratified by sex and age) to the Youth Readiness Intervention (YRI) (n = 222) or to a control condition (n = 214). After treatment, youth were again randomized and offered an education subsidy immediately (n = 220) or waitlisted (n = 216). Emotion regulation, psychological distress, prosocial attitudes/behaviors, social support, functional impairment, and posttraumatic stress disorder (PTSD) symptoms were assessed at pre- and postintervention and at 6-month follow-up. For youth in school, enrollment, attendance, and classroom performance were assessed after 8 months. Linear mixed-effects regressions evaluated outcomes.The YRI showed significant postintervention effects on emotion regulation, prosocial attitudes/behaviors, social support, and reduced functional impairment, and significant follow-up effects on school enrollment, school attendance, and classroom behavior. In contrast, education subsidy was associated with better attendance but had no effect on mental health or functioning, school retention, or classroom behavior. Interactions between education subsidy and YRI were not significant.YRI produced acute improvements in mental health and functioning as well as longer-term effects on school engagement and behavior, suggesting potential to prepare war-affected youth for educational and other opportunities.

Project description:BackgroundDiabetes disproportionately affects African Americans and is associated with poorer outcomes. Self-management is important for glycemic control; however, evidence in African Americans is limited.ObjectiveTo assess the efficacy of a combined telephone-delivered education and behavioral skills intervention (TBSI) in reducing hemoglobin A1c (HbA1c) levels in African Americans with type 2 diabetes, using a factorial design.DesignThis is a four-year randomized clinical trial, using a 2 x 2 factorial design.: Participants: African American adults ≥18 years) with poorly controlled type 2 diabetes (HbA1c ≥9%) were randomly assigned to one of four groups: 1) knowledge only, 2) skills only, 3) combined knowledge and skills (TBSI), or 4) control group.InterventionAll participants received 12 telephone-delivered 30-min intervention sessions specific to their assigned group. Participants were assessed at baseline and 3, 6, and 12 months.Main measureThe primary outcome was HbA1c at 12 months post-randomization in the intent-to-treat (ITT) population.Key resultsTwo hundred fifty-five participants were randomly assigned to the four groups. Based on the ITT population after multiple imputation, the analysis of covariance with baseline HbA1c as the covariate showed that HbA1c at 12 months for the intervention groups did not differ significantly from that of the control group (knowledge: 0.49, p = 0.123; skills: 0.23, p = 0.456; combined: 0.48, p = 0.105). Absolute change from baseline at 12 months for all treatment arms was 0.6. Longitudinal mixed effects analysis showed that, on average, there was a significant decline in HbA1c over time for all treatment groups (-0.07, p < 0.001). However, the rates of decline for the intervention groups were not significantly different from that of the control group (knowledge: 0.06, p = 0.052; skills: 0.02, p = 0.448; combined: 0.05, p = 0.062). Results from per-protocol populations were similar.ConclusionsFor African Americans with poorly controlled type 2 diabetes, combined education and skills training did not achieve greater reductions in glycemic control (i.e., HbA1c levels) at 12 months compared to the control group, education alone, or skills training alone. This trial is registered with ClinicalTrials.gov, identifier no. NCT00929838.
