Theoretical frameworks informing family-based child and adolescent obesity interventions: A qualitative meta-synthesis

The problem of heteronormativity in family-based health promotion: centring gender transformation in Ontario, Canada

OBJECTIVES

Social scientists have demonstrated that family health work is interlinked with heteronormative gender inequities. Yet family-based public health interventions rarely incorporate a gender transformative approach or address heteronormativity as a potential health barrier in North America. Instead, attention to gender surfaces primarily in family health interventions conducted in low- to middle-income countries with majority Black and racialized populations. The objective of this article is to establish the importance of designing health interventions that account for heteronormative relations in Ontarian families by drawing on empirical data from the Guelph Family Health Study (GFHS).

METHODS

We draw on data (February-October 2019) from (1) semi-structured interviews with 20 families and with 4 health educators facilitating the GFHS home visits and (2) observational data of 11 GFHS home visits and 1 health educator training day. Informed by gender transformation theory, data were analyzed and coded to understand the impact of gender, sexuality, and place in family health interventions.

RESULTS

Pre-existing heteronormative parenting relations were reinforced through GFHS participation: the GFHS was mother-led, increasing some mothers' stress levels. Fathers tended to consider paid work a justification for disengaging from the GFHS, and their detachment sometimes obstructed mothers' intervention efforts. Health educators (all women) were caught in these relations, feeling like because of their gender, they were viewed by parents as confidants and marriage counsellors.

CONCLUSION

Findings emphasize the need for expanding the epistemic and methodological approaches to family-based health interventions, changing the demographic and geographic emphasis within the field, and designing interventions that focus on societal-level changes. Heterosexuality has not been analyzed as a risk factor within the public health field, but our findings indicate the need for further study.

The Relationship Between Social Integration and Physical Activity, Diet, and Sleep Among Youths: Cross-sectional Survey Study

BACKGROUND

Social integration has been shown to predict physical activity (PA), diet, and sleep in adults. However, these associations have not been well-studied in youth samples. Using a life course perspective, it is imperative to study this in youths as social and health behaviors are established early in life.

OBJECTIVE

The purpose of this study was to understand the relationship between social integration and PA, diet, and sleep for urban, middle-school youth.

METHODS

Cross-sectional baseline data from middle-school youths (N=73) who participated in an afterschool health behavior intervention were included in this study.

RESULTS

Time with friends significantly predicted moderate to vigorous intensity PA (β=.33, P=.02). Time spent with family was significantly related to fruit consumption (t₆₆=1.38, P=.005) and vegetable consumption (t₇₂=1.96, P=.01).

CONCLUSIONS

Social integration appears to be related to both PA and nutrition behaviors in youths. Future research should expand on our findings to explain how different domains of social integration may impact youths' health behaviors.

Changes in perceived parental self-efficacy after a Child-Centred Health Dialogue about preventing obesity

Aim

This randomised controlled trial evaluated changes in parental self‐efficacy and children's weight, after a Child‐Centred Health Dialogue about preventing obesity.

Methods

We randomly assigned 37 Child Health Centres in Skåne county Sweden to provide usual care or the dialogue intervention. They included centres from high and low socioeconomic areas. The outcomes were changes in parental self‐efficacy and any moderating effect on their children's body mass index 1 year later.

Results

The baseline data were based on 1115 mothers and 869 fathers representing 1197 children (52% females) aged 4 years (3.9–4.2) with a standardised body mass index (zBMI) of 0.1 ± 0.9. The participation rates at follow‐up, 1.1 ± 0.2 years after the intervention were 817 mothers and 508 fathers. Overall, parental self‐efficacy had decreased by the 1‐year follow‐up. There was a significant intervention effect on maternal self‐efficacy in promoting physical activity, however with unclear clinical relevance. Mothers' change in perceived self‐efficacy in promoting a healthy diet seemed to moderate the intervention effect on zBMI change in children with zBMI > 0 with −0.01 (95% CI: −0.025 to −0.001; p = 0.03).

Conclusion

Our study suggested a possible link between increased maternal self‐efficacy in promoting a healthy diet and a favourable development of zBMI.

A multi-component tailored intervention in family childcare homes improves diet quality and sedentary behavior of preschool children compared to an attention control: results from the Healthy Start-Comienzos Sanos cluster randomized trial

BACKGROUND

Childcare settings are important environments for influencing child eating and physical activity (PA). Family childcare homes (FCCH) care for many children of low-income and diverse racial/ethnic backgrounds who are at greater risk for poor diet quality, low PA, and obesity, but few interventions have targeted this setting. The aim of this study was to assess the efficacy of a multicomponent intervention conducted in FCCH on the diet quality and PA of 2-5 year old children in their care.

TRIAL DESIGN

Cluster randomized trial.

METHODS

The cluster-randomized trial, Healthy Start/Comienzos Sanos (2015-2019) evaluated an 8-month nutrition and PA intervention that included four components: (1) monthly telephone calls from a support coach using brief motivational interviewing, (2) tailored reports, newsletters and videos, (3) group support meetings, and (4) active play toys. After completing baseline measurement, FCCH were randomized into intervention or comparison groups in matched pairs. Both groups received the same intervention components but on different topics (intervention: nutrition/PA vs. comparison: reading readiness/literacy). Evaluation staff were blinded to group assignment. Child primary outcome measures collected at baseline and 8-months included: 1) Healthy Eating Index (HEI-2015) scores calculated from diet observation, and 2) accelerometer measurement of PA. Process measures were collected from field data and provider surveys. Generalized Estimating Equation Models assessed changes in HEI-2015 scores and PA over time by experimental condition.

RESULTS

Ethnically diverse FCCH providers (n = 119) and 2-to-5-year-old children in their care (n = 377) were included in the final analysis. Process evaluation showed high participation in all intervention components except for group meetings. Compared to children in comparison group FCCH, children in intervention FCCH increased total HEI-2015 scores by 7.2 points (p < .001) including improvement in component scores for vegetables (0.84 points, p = .025) and added sugar (0.94 points, p = .025). For PA, compared to children in the comparison group, children in intervention FCCH decreased sedentary time by 5.7% (p = .021).

CONCLUSIONS

The multicomponent Healthy Start intervention was effective in improving diet quality and sedentary behavior of children in FCCH, which demonstrates the promise of obesity prevention interventions in this setting. Future research could include enhancing the Healthy Start intervention to strengthen the PA component, considering virtual peer support, and determining how to best translate and disseminate the intervention into FCCH nationally.

Designing an adolescent physical activity and nutrition intervention before and after COVID-19: A formative research study

BACKGROUND

With rates of childhood obesity continually increasing, effective physical activity (PA) and nutrition interventions are needed. Formative research is used to tailor interventions to different cultural and geographic contexts and can also be vital in adapting intervention strategies in the face of significant disruptive circumstances (like COVID-19).

OBJECTIVE

We conducted formative research via in-person and online focus groups among middle schoolers and parents to better understand barriers and facilitators to PA and fruit and vegetable (FV) consumption and inform the design of a large intervention for a low-income, urban setting in the U.S. Midwest.

METHODS

We conducted two phases of qualitative focus groups with parents (n=20) and 6-9 grade middle schoolers (n=22). Phase 1 was conducted prior to the COVID-19 pandemic in late 2019, and phase 2 was conducted during the COVID-19 pandemic in the summer of 2020. Focus groups were transcribed and thematically coded using Dedoose software.

RESULTS

Main facilitators to PA prior to the pandemic included the opportunity to have fun, peer influence, competition (for some), and incentives, while main barriers to PA were time constraints and social discomfort. Main facilitators to eating FV included parental influence, preparation technique, and convenience, while barriers included dislike of vegetables, time constraints, and preparation or freshness. During the pandemic, facilitators to PA remained the same, while additional barriers to PA such as lack of motivation and limited time spent outside of the home were reported during the pandemic. For FV consumption, both facilitators and barriers remained the same for both time periods. Additionally, for some participants, the pandemic offered an opportunity to offer more FV to middle schoolers throughout the day.

CONCLUSIONS

Some themes identified were common to those reported in previous studies, such as peer influence on PA and parental influence on FV consumption. Novel themes, such as lack of motivation to be active and limited time outside the home, helped improve intervention adaptation, specifically during the COVID-19 pandemic. The continuity of formative research after a major, unexpected change in intervention context can be essential in targeting areas of an intervention that can be retained and those that need to be adjusted.

Effectiveness of Family-Based Behavior Change Interventions on Obesity-Related Behavior Change in Children: A Realist Synthesis

Effective treatment interventions for childhood obesity involve parents, are multicomponent and use behavior change strategies, but more information is needed on the mechanisms influencing behavioral outcomes and the type of parental involvement that is efficacious in behavioral treatment interventions with school-age children. This review aimed to understand key characteristics of programs that contribute to dietary and physical activity behavioral outcomes, and through which key mechanisms. This was a systematic review with narrative synthesis following PRISMA guidelines and realist analysis using RAMESES guidelines to explain outcome patterns and influence of parental involvement. Overall, the findings contribute to understanding the complex relationship between family barriers to behavior change, strategies employed in treatment interventions and behavioral outcomes. Implications for enhancing future policy and practice include involving parents in goal setting, motivational counselling, role modeling, and restructuring the physical environment to promote mutual empowerment of both parents and children, shared value and whole-family ownership in which intrinsic motivation and self-efficacy are implicit. These characteristics were associated with positive dietary and physical activity behavior change in children and may be useful considerations for the design and implementation of future theory-based treatment interventions to encourage habitual healthy diet and physical activity to reduce childhood obesity.

The role of theories in interventions targeting preteens with Type 1 diabetes: A critical literature review

BACKGROUND

Theory-based interventions have been recommended to target relevant issues and improve outcomes in children and adolescents with Type 1 diabetes. Furthermore, the timing of interventions has been recognized as key to improving outcomes, suggesting a need to focus on preteens (9-12 years old) with Type 1 diabetes. The aim of the present study was to identify the theories that inform interventions targeting preteens with Type 1 diabetes and to analyse the studies for their understandings of theory.

METHODS

We conducted a systematic literature review of intervention studies targeting preteens with Type 1 diabetes to identify the theoretical frameworks applied. Seven databases across different scientific disciplines were searched for papers published between 1995 and 2018.

RESULTS

Twenty-four studies were included in the review. Of these, 14 were categorized as theory-inspired and 10 as theory-related studies. Social cognitive theory appeared most frequently. Most studies did not provide a rationale for their choice and application of theory to inform interventions. The studies were characterized by use of adult-centric theories and a focus on the relationships between children and their parents.

CONCLUSIONS

The present review shows variations and limitations in the description and application of theories across interventions targeting preteens with Type 1 diabetes. This emphasizes the need for future studies to address for what reason and how a certain theory or method is applied. We suggest that interventions might benefit from using theories that are centred on the needs and experiences of children, target family dynamics that include all important family members, and address the mutually constitutive relationship between interventions and the social context in which they are implemented.

Development of an intervention program to prevent childhood obesity targeted to Mexican mothers of school-aged children using intervention mapping and social cognitive theory

In Mexico, data from the last National Health and Nutrition Survey (2016) described the increase in the prevalence of overweight and obesity in school-aged children (33.2%). Obesity prevention strategies have not been effective, and currently, Mexico has one of the highest prevalence of childhood obesity. Thus, there is an urgent need to develop strategies that can prevent childhood obesity and also to avoid these children to remain overweight/obese through adulthood. The objective of this study was to provide a step-by-step description of the design, implementation and evaluation of an intervention plan for Mexican mothers of school aged children to promote healthy eating and to prevent childhood obesity. The program Niño Sano Adulto Sano was developed using the Intervention Mapping Approach and the Social Cognitive Theory frameworks to provide Mexican mothers with knowledge and skills to positively modify their children's food behavior, thus preventing future weight gain. The program was developed, piloted and delivered to the target population with positive results on the mothers' nutrition knowledge and children's BMI. Intervention Mapping and Social Cognitive Theory are useful models to design and deliver an intervention that provides a holistic approach to promote healthy eating.

Improving nutrition and physical activity environments of family child care homes: the rationale, design and study protocol of the 'Healthy Start/Comienzos Sanos' cluster randomized trial

BACKGROUND

Early childhood is a crucial time to foster healthy eating and physical activity (PA) habits, which are critical for optimal child health, growth and development. Child care facilities are important settings to promote healthy eating and PA and prevent childhood obesity; however, almost all prior intervention studies have focused on child care centers and not family child care homes (FCCH), which care for over 1.6 million U.S. children.

METHODS

This paper describes Healthy Start/Comienzos Sanos, a cluster-randomized trial evaluating the efficacy of a multicomponent intervention to improve nutrition and PA environments in English and Spanish-speaking FCCH. Eligible child care providers complete baseline surveys and receive a two-day FCCH observation of the home environment and provider practices. Parent-consented 2-5 year-old children are measured (height, weight, waist circumference), wear accelerometers and have their dietary intake observed during child care using validated protocols. FCCH providers are then randomly assigned to receive an 8-month intervention including written materials tailored to the FCCH providers' need and interest, videos, peer support coaching using brief motivational interviewing, and periodic group meetings focused on either nutrition and PA (Intervention) or reading readiness (Comparison). Intervention materials focus on evidence-based nutrition and physical activity best practices. The initial measures (surveys, two-day observation of the FCCH and provider practices, child diet observation, physical measures, and accelerometer) are assessed again 8 and 12 months after the intervention starts. Primary outcomes are children's diet quality (Healthy Eating Index), time in moderate and vigorous PA and sedentary PA during child care. Secondary outcomes include FCCH provider practices and foods served, and PA environments and practices. Possible mediators (provider attitudes, self-efficacy, barriers and facilitators) are also being explored. Process evaluation measures to assess reach, fidelity and dose, and their relationship with dietary and PA outcomes are included.

DISCUSSION

Healthy Start/Comienzos Sanos fills an important gap in the field of childhood obesity prevention by rigorously evaluating an innovative multicomponent intervention to improve the nutrition and physical activity environments of FCCH.

"C.H.A.M.P. Families": Description and Theoretical Foundations of a Paediatric Overweight and Obesity Intervention Targeting Parents-A Single-Centre Non-Randomised Feasibility Study

Childhood obesity represents a significant global health challenge, and treatment interventions are needed. The purpose of this paper is to describe the components and theoretical model that was used in the development and implementation of a unique parent-focussed paediatric overweight/obesity intervention. C.H.A.M.P. Families was a single-centre, prospective intervention offered to parents of children aged between 6–14 years with a body mass index (BMI) ≥85th percentile for age and sex. The intervention included: (1) eight group-based (parent-only) education sessions over 13-weeks; (2) eight home-based activities; and (3) two group-based (family) follow-up support sessions. The first section of the manuscript contains a detailed description of each intervention component, as well as an overview of ongoing feasibility analyses. The theoretical portion details the use of evidence-based group dynamics principles and motivational interviewing techniques within the context of a broader social cognitive theory foundation. This paper provides researchers with practical examples of how theoretical constructs and evidence-based strategies can be applied in the development and implementation of parent-focussed paediatric obesity interventions. Given the need for transparent reporting of intervention designs and theoretical foundations, this paper also adds to the areas of implementation science and knowledge translation research.
