Context matters in pediatric obesity: commentary on innovative treatment and prevention programs for pediatric overweight and obesity

Scaling and sustaining research tested interventions: Lessons learned from Rhode Island Childhood Obesity Research Demonstration 3.0

Childhood obesity is a significant health problem associated with negative physical and mental health outcomes. Although evidence-based family healthy weight programs (FHWPs), such as JOIN for ME, have been developed, there is a significant lag before these are disseminated more broadly. This study outlines the process of participating in the Speeding Research-tested Interventions (SPRINT) program, highlighting lessons learned, to increase the reach of a previously tested and efficacious FHWP, JOIN for ME. Qualitative interviews were conducted with policymakers, benefits providers, employers, philanthropists, community stakeholders, and medical providers to iteratively test the developed JOIN for ME business model and identify themes regarding effective scaling and sustainability of an evidence-based FHWP. Rapid qualitative analysis of 45 interviews identified four key themes regarding scaling of an FHWP. These were (i) virtual program delivery, (ii) focus on equity, (iii) return on investment, and (iv) tie-in to local community. The process of engaging stakeholders from multiple backgrounds is critical to refining an efficacious program to ensure scalability and sustainment. The SPRINT process allows researchers to understand the marketplace for evidence-based interventions and develop adaptations for sustaining and scaling research tested programs.

Contextual Complexities in Implementing a Family-Based Childhood Obesity Intervention: The Perspectives of Enrolled Children and Their Parents

Family interventions to treat childhood obesity are widely used, but knowledge about how family dynamics are affected by these interventions is lacking. The present study aims to understand how a family intervention impacts the context of family dynamics, and how different contexts affect the families’ implementation of the intervention. Based on qualitative interviews, we studied families with a child between 9–12 years enrolled in a family intervention to treat childhood obesity at a pediatric outpatient clinic. We conducted 15 family interviews including 36 family members. We found that the family intervention created a new context for the enrolled children. They had to navigate in different contexts and non-supportive environments and push for change if they needed more supportive environments in their attempt to adhere to healthy habits. We show the complexities experienced by parents and grandparents when trying to comply with siblings’ and/or grandchildren’s different needs. The enrolled children were often indirectly blamed if others had to refrain from unhealthy preferences to create supportive environments. These findings are significant in understanding the important role of contexts in family-obesity interventions. This knowledge is relevant to health professionals, researchers, and policymakers.

A cultural adaptation and validation of a child eating behaviour measure in a low- and middle-income country

OBJECTIVE

The Child Eating Behaviour Questionnaire (CEBQ), a widely used instrument that has been validated mostly in high-income countries, has limitations in its factorial validity when used among different cultures. This study examines whether the CEBQ instrument is culturally appropriate and valid to be used in a low- and middle-income country (LMIC) in a setting where child undernutrition remains prevalent.

DESIGN

The study employed a qualitative process to validate the content of items relative to the culture and setting, which was followed by a survey to test the psychometric properties of the instrument. Tests of factorial validity, convergent validity and reliability were performed.

SETTING

Three different socio-economic settings of Yogyakarta, Indonesia.

PARTICIPANTS

The participants of this study were mothers of children aged 25-60 months. In-depth interviews were conducted with twenty-four mothers and the questionnaire validation process involved 238 mothers in the survey.

RESULTS

A Confirmatory Factor Analysis model with eight subscales provided the best fit (root-mean-square error of approximation = 0·048 (90 % CI 0·040, 0·057); Comparative Fit Index = 0·95 and Tucker Lewis Index = 0·95) after three new items and eight items from the original CEBQ were removed. Convergent validity with child's weight was found for two subscales, slowness in eating and satiety responsiveness. Reliability measured using Cronbach's alpha provided values between 0·62 and 0·78.

CONCLUSION

The original eight-factor structure of the CEBQ showed adequate content validity and provided factorial, discriminant and convergent validity with mothers of preschool children living in a LMIC where child nutrition remains a significant public health issue.

Dyslipidemia management in overweight or obese adolescents: A mixed-methods clinical trial of motivational interviewing

Background:

Lifestyle management for dyslipidemic adolescents often occurs in the context of family-centered care, which necessitates adaptation of counseling strategies.

Objective:

To determine the effectiveness of motivational interviewing for lifestyle behavior change for dyslipidemic adolescents in a dyad with a parent versus alone.

Methods:

A total number of 32 adolescents were randomized 1:1 to receive a series of motivational interviewing sessions either together with a parent or alone for a 6-month intervention, with both quantitative and qualitative assessment of outcomes.

Results:

Both groups were similar at baseline. Following the intervention, there were no significant differences between groups in physical, laboratory, lifestyle or psychosocial measures, except for a reduction in dietary fats/sugars (p = 0.02) and in screen time (p = 0.02) in the alone group. When both groups were combined, significant reductions at 6 months were noted for body mass index (p < 0.001), waist circumference (p < 0.001), total cholesterol (p < 0.001), low-density lipoprotein cholesterol (p < 0.001), triglycerides (p = 0.01), non–high-density lipoprotein cholesterol (p < 0.001), fasting insulin (p = 0.01), and homeostatic model (p = 0.02). Reduced screen time and increased fruit and vegetable intake were also noted for both groups combined. These changes were also reflected in self-efficacy (p = 0.004), self-esteem (p = 0.03), and improvement in quality of life measures. Interview data provided insights into the utility and acceptability of the motivational interviewing intervention.

Conclusion:

Motivational interviewing was an efficient strategy for inspiring healthy lifestyle and physiological changes among adolescents in both groups. Family centered pediatric approaches should consider the autonomy and individual preferences of the adolescent prior to counseling.

Development and psychometric evaluation of a context-based parental self-efficacy instrument for healthy dietary and physical activity behaviors in preschool children

Background

Parental self-efficacy (PSE) refers to beliefs of parents to effectively engage in behaviors that result in desired outcomes for their children. There are several instruments of PSE for promoting healthy dietary or physical activity (PA) behaviors in children. These measures typically assess PSE in relation to some quantity or frequency of behavior, for example, number of servings or times per week. However, measuring PSE in relation to contextual circumstances, for example, psychological states and situational demands, may be a more informative approach. The purpose of the present study was to develop and psychometrically evaluate a context-based PSE instrument.

Methods

Swedish mothers of five-year-old children (n = 698) responded to the Parental Self-Efficacy for Healthy Dietary and Physical Activity Behaviors in Preschoolers Scale (PDAP) and a questionnaire on dietary and PA behaviors in children. Interviews were conducted to explore participant perceptions of the quality of the PDAP items. Psychometric evaluation was conducted using exploratory and confirmatory factor analyses. Spearman correlations between PSE and child behaviors were examined.

Results

Twenty-seven interviews were conducted with participants, who perceived the items as highly comprehensible, relevant and acceptable. A four-factor model of a revised 21-item version of the PDAP fitted the data, with different factors of PSE for promoting healthy dietary or PA behaviors in children depending on whether circumstances were facilitating or impeding successful performance. Internal consistency was excellent for total scale (Cronbach’s α = .94), and good for factors (α = .84–.88). Correlations were in the expected direction: positive correlations between PSE and healthy behaviors, and negative correlations between PSE and unhealthy behaviors (all r_ss ≤ .32).

Conclusions

Psychometric evaluation of the PDAP provided preliminary support of construct validity and internal consistency.

Promoting healthful family meals to prevent obesity: HOME Plus, a randomized controlled trial

Background

Family meal frequency has been shown to be strongly associated with better dietary intake; however, associations with weight status have been mixed. Family meals-focused randomized controlled trials with weight outcomes have not been previously conducted. Therefore, this study purpose was to describe weight-related outcomes of the HOME Plus study, the first family meals-focused randomized controlled trial to prevent excess weight gain among youth.

Methods

Families (n = 160 8-12-year-old children and their parents/guardians) were randomized to intervention (n = 81) or control (n = 79) groups. Data were collected at baseline (2011–2012), post-intervention (12-months post-baseline) and follow-up (21-months post-baseline). The intervention included ten monthly group sessions (nutrition education; hands-on meal and snack planning, preparation, and skill development; screen time reductions) and five motivational, goal-setting phone calls. The main outcome was child body mass index (BMI) z-score.

Results

General linear models, adjusted for baseline values and demographics, showed no significant treatment group differences in BMI z-scores at post-intervention or follow-up; however, a promising reduction in excess weight gain was observed. Post-hoc stratification by pubertal onset indicated prepubescent children in the intervention group had significantly lower BMI z-scores than their control group counterparts.

Conclusions

The study used a strong theoretical framework, rigorous design, quality measurement and a program with high fidelity to test a family meals-focused obesity prevention intervention. It showed a modest decrease in excess weight gain. The significant intervention effect among prepubescent children suggests the intervention may be more efficacious among relatively young children, although more research with appropriately powered samples are needed to replicate this finding.

Beyond BMI: The Next Chapter in Childhood Obesity Management

Pediatric obesity treatment has traditionally focused on body mass index (BMI) and has had limited success. Recent research has suggested new ways to approach this topic that focuses more on holistic measures of health and inclusion of a larger population of children. This paper discusses new evidence in the prevention of chronic disease and treatment of obesity that has a body positive and mental health lens as well as integrating research from several areas of health, including the prevention of chronic disease. Practical medical and mental health assessments tools are suggested for clinical use. Implications for an individualized, positive treatment future are presented.
