Family-Based Obesity Prevention Interventions among Hispanic Children and Families: A Scoping Review

Acceptability of community health worker and peer supported interventions for ethnic minorities with type 2 diabetes: a qualitative systematic review

Objective

Ethnic minority groups in high income countries in North America, Europe, and elsewhere are disproportionately affected by T2DM with a higher risk of mortality and morbidity. The use of community health workers and peer supporters offer a way of ensuring the benefits of self-management support observed in the general population are shared by those in minoritized communities.

Materials and methods

The major databases were searched for existing qualitative evidence of participants' experiences and perspectives of self-management support for type 2 diabetes delivered by community health workers and peer supporters (CHWPs) in ethnically minoritized populations. The data were analysed using Sekhon's Theoretical Framework of Acceptability.

Results

The results are described within five domains of the framework of acceptability collapsed from seven for reasons of clarity and concision: Affective attitude described participants' satisfaction with CHWPs delivering the intervention including the open, trusting relationships that developed in contrast to those with clinical providers. In considering Burden and Opportunity Costs, participants reflected on the impact of health, transport, and the responsibilities of work and childcare on their attendance, alongside a lack of resources necessary to maintain healthy diets and active lifestyles. In relation to Cultural Sensitivity participants appreciated the greater understanding of the specific cultural needs and challenges exhibited by CHWPs. The evidence related to Intervention Coherence indicated that participants responded positively to the practical and applied content, the range of teaching materials, and interactive practical sessions. Finally, in examining the impact of Effectiveness and Self-efficacy participants described how they changed a range of health-related behaviours, had more confidence in dealing with their condition and interacting with senior clinicians and benefitted from the social support of fellow participants and CHWPs.

Conclusion

Many of the same barriers around attendance and engagement with usual self-management support interventions delivered to general populations were observed, including lack of time and resource. However, the insight of CHWPs, their culturally-sensitive and specific strategies for self-management and their development of trusting relationships presented considerable advantages.

Early childhood (1-5 years) obesity prevention: A systematic review of family-based multicomponent behavioral interventions

INTRODUCTION

Globally 38.9 million children under age 5 have overweight or obesity, leading to type 2 diabetes, cardiovascular complications, depression, and poor educational outcomes. Obesity is difficult to reverse and lifestyle behaviors (healthy or unhealthy) can persist from 1.5 years of age. Targeting caregivers to help address modifiable behaviors may offer a viable solution.

OBJECTIVE

Evaluate the impact of multicomponent family interventions on weight-based outcomes in early childhood and explore related secondary behavior outcomes.

METHODS

Four databases were searched (1/2017-6/2022) for randomized controlled trials (RCTs) of obesity-prevention interventions for children (1-5 years). Eligible studies included an objectively measured weight-based outcome, family interventions targeting the caregiver or family, and interventions including at least two behavioral components of nutrition, physical activity, or sleep.

RESULTS

Eleven interventions were identified consisting of four delivery modes: self-guided (n = 3), face-to-face group instruction (n = 3), face-to-face home visits (n = 2), and multiple levels of influence (n = 3). The reviewed studies reported almost no significant effects on child weight-based outcomes. Only two studies (one was an underpowered pilot study) resulted in significant positive child weight-management outcomes. Seven of the interventions significantly improved children's dietary intake.

CONCLUSION

Except for one, the reviewed studies reported that family based interventions had no significant effects on child weight-based outcomes. Future studies of this type should include measurements of age and sex-based body mass index (BMI) and trajectories, and also examine other important benefits to the children and families.

Change in Nutrition Behavior After Participating in an Obesity-Related Cancer Education Program in El Paso, Texas

BACKGROUND

Roughly 25% of the U.S- Border city, El Paso, Texas is obese. Obesity is a major risk factor for 13 cancers. Cancer is the leading cause of death in El Paso. Therefore, there is a growing urgency to implement evidence-based programs that support behavioral change that helps curb the impact of obesity in El Paso and the U.S.-Mexico border region.

PURPOSE

This study aimed to assess the effectiveness of an obesity-related cancer prevention program (Pasos Para Prevenir Cancer (PPPC) on changes in participant nutrition behaviors.

METHODS

Culturally tailored, theory-based education was provided to adults through the PPPC program. A total of 256 PPPC participants agreed to take part in our program evaluation. Participants were asked to complete a survey at baseline and 6 months after they completed the program. Session included topics on obesity-related cancers, assessing your obesity risk, measuring body fat, SMART goal setting, and how to find the right type of physical activity. For this report we used the Food Frequency Questionnaire (FFQ) data to assess changes between baseline and six months. We also used perceived dietary barriers as moderators on the relationship between program participation and nutrition behaviors.

RESULTS

Most participants (92.2%) identified as being of Mexican American descent, were between the ages of 41-75 years of age (n = 165) and identified as females (n = 225). 48.1% of the participants were born in Mexico while 50.4% were born in the U.S. Approximately 35-51% of participants improved and sustained their intake of healthier foods at 6 month follow up. Specifically, there was a statistically significant shift from higher fat and sugar content foods to light and low-fat foods, and fruits and vegetables. Participants also increased their consumption of ground chicken, lean red meat, and seafood. A key modifier in this relationship is perceived health risk.

CONCLUSION

Latinos on the U.S.-Mexico border ascribe to a healthy living mindset. In general, they frequently eat fruits and vegetables. Participation in PPPC increased perceived barriers to healthy living around cost and convenience and enhanced decision-making around healthier options. Participants responded to our adapted evidence-based program resulting in sustained changes in nutrition behaviors. Using adapted evidence-based strategies developed outside of the U.S.-Mexico border region is a feasible approach to address persist health disparities.

Parental and familial factors related to participation in a home-based physical activity intervention in children with obesity or Prader-Willi syndrome

Background

Increasing physical activity (PA) participation is vital to promote the development of health behaviors in childhood. This study examined which parental and familial factors predicted completion of and compliance with a home-based family PA program in a cohort of families with a child with Prader-Willi syndrome (PWS; a rare disorder with obesity and developmental disability) or with obesity but with neurotypical development.

Methods

Participants (n = 105) were parents of children with PWS (n = 41) and parents of children with obesity but without PWS (n = 64). Parents completed a series of questionnaires documenting their demographic characteristics, self-efficacy, social support, and family environment (active-recreational orientation and cohesion). Relationships between these factors and intervention completion and compliance were evaluated using bivariate correlations and logistic regression (compliance) and multiple regression (completion) analyses with groups together and then separately if the child group was a significant predictor.

Results

None of the variables of interest (marital status, employment, employed hours per week, self-efficacy, social support, and family environment) were significant predictors of intervention completion. Intervention compliance was negatively associated with parents working part-time and working full-time and positively associated with family cohesion (Model R2 = 0.107, F(3,100) = 4.011, p = .010). Child group was not a factor.

Conclusions

Compliance with a 24-week family home-based PA intervention was related to fewer employment hours of the primary caregiver and family environment factors. Future interventions should consider how to reduce the intervention's burden in working parents along with strategies to foster family cohesion.

Social determinants of health of racial and ethnic minority adolescents: An integrative literature review

Integration of adolescents with diverse cultural backgrounds into the country of residence is associated with some form of rejection and discrimination, predisposing them to undesirable health outcomes. In this regard, the aim of this study was to identify the social determinants of the health of racial and ethnic minority adolescents. In this integrative literature review, PubMed, EMBASE, Cochrane Library, and CINAHL databases were searched from 2016 to 2021 and studies were selected according to the PRISMA 2020 guidelines. Health status was limited to health outcomes according to the definition proposed by the World Health Organization and Healthy People 2020. The social determinants of health were classified according to the research framework of the National Institute on Minority Health and Health Disparities. Six types of health status were identified: self-rated health, obesity and overweight, global self-worth, emotional well-being, anthropometric measurement, and psychosocial adjustment. The social determinants of health were at the individual and interpersonal level, and the domains included the biological (gender, illness experience), psychological (acculturative stress), and sociocultural environment (e.g., socioeconomic status, parents' educational level, household death due to violence). Therefore, future research must prioritize their sociocultural environments to reduce the negative impact of discrimination and sociocultural and structural differences on racial and ethnic minority adolescents.

School-Based Versus Family-Based Interventions for the Reversal and Prevention of Obesity Among Hispanic Youth: a Review of the Literature

Childhood obesity prevalence in the USA continues to rise and the Hispanic American population is disproportionately affected. Obesity prevalence among Hispanic youth is 26.2%, the highest prevalence of any minority or non-minority group of children. Prevalence of related conditions including type 2 diabetes, heart disease, and stroke also are increased among Hispanic Americans. Physicians and other providers commonly utilize body mass index (BMI) to estimate percentage of bodily fat and risk of adverse health outcomes. BMI has been shown to track from childhood to adulthood, demonstrating necessity for early intervention. Interventions targeting the prevention and reversal of obesity among children are categorized as school-based or family-based. Interventions vary but may involve strategies such as meetings to discuss health-related curriculum, augmentation of physical activity, and/or improvement of nutritional quality of food. The aim of this article is to review the current literature to determine whether family-based or school-based interventions are more successful in the prevention and reversal of obesity among Hispanic youth. We reviewed twenty-eight studies describing these interventions and included ten (four school-based and six family-based) in our in-depth analysis. Inclusion criteria required trials were conducted among adequate population sizes of Hispanic youth within the age range of interest, analyzed the primary outcome of interest, and took place after the year 2000. Family-based interventions typically involved small population sizes, were dependent upon parent adherence, and were rarely effective. School-based interventions were more commonly effective and involved larger population sizes, allowing for greater generalizability and greater impact of the intervention. Of five family or school-based interventions which successfully reduced BMI among this population, four included a component involving structured physical activity. School-based interventions involving augmentation of physical activity with minimal limitations of study execution demonstrated efficacy in the prevention and reversal of obesity among Hispanic children.

Randomized control trial of a childhood obesity prevention family-based program: "Abriendo Caminos" and effects on BMI

Background

Hispanic individuals are at increased risk for obesity and other chronic health conditions. This article evaluates the effect of a family-based, childhood obesity primary prevention intervention in a community setting.

Methods

A multi-site, randomized controlled trial community program with assessments at pre (T0), post-program (T1), and 6-months post-program (T2). Participating families were recruited from five sites. Only families of Mexican or Puerto Rican heritage with a least one child between 6 and 18 years were included in the study, without weight restrictions. Families were randomized to the intervention and control arms. Intervention families received six-2 h weekly workshops. Control families received printed generic nutrition and wellness information. Heights and weights were measured at the 3-time points to calculate BMI z-scores, BMI-percentiles, and weight status using age- and sex-specific growth charts, according to the CDC guidelines.

Results

There were no differences in BMI-z scores between children in the intervention (n = 239) and control groups (n = 187) at T0. BMI z-scores decreased in the intervention group (-0.03, 95% CI, -0.066, -0.003, p = 0.032) at T1, but not in the control group at T1. Changes in BMI z-scores were not statistically significant at T2.

Conclusion

The Abriendo Caminos intervention effectively prevented unhealthy weight gain in Hispanic children in the short-term, but not at 6-months post-intervention. Younger children and girls benefited more from the program at 6-months post-intervention. Additional efforts are needed to sustain long-term changes. Culturally-tailored programs can provide families with the knowledge to produce short-term changes and a potential pathway for sustainable changes in implementing healthy behaviors.

Technology-Based Obesity Prevention Interventions Among Hispanic Adolescents in the United States: Scoping Review

BACKGROUND

Given that today's adolescents are digital front-runners, technology-based obesity prevention strategies are age-appropriate for this population. The use of remote and wireless technologies may be suitable for extending the reach and engagement of obesity prevention efforts among high-risk Hispanic youths, as this subgroup is disproportionately affected by barriers that limit participation in traditional, in-person interventions.

OBJECTIVE

The purpose of this scoping review was to examine the intervention and sample characteristics of technology-based obesity prevention interventions among Hispanic adolescents. We also examined feasibility criteria to assess the acceptability and appropriateness of technology-based strategies among Hispanic youths.

METHODS

A comprehensive search of Embase and PubMed identified 7 studies that met the inclusion criteria. Data were extracted by 2 independent reviewers.

RESULTS

Of the 7 included studies, half (n=4, 57%) used a randomized control trial design, with equal implementation in school (n=3, 43%) and clinic (n=4, 57%) settings. Studies commonly targeted improvements in diet (n=4, 57%) and physical activity (n=7, 100%), with only 1 (14%) study focused on sedentary behaviors. Just 2 (29%) studies reported the use of behavioral theories or models. Studies focused primarily on youths in early (n=5, 71%) or middle (n=6, 86%) adolescence, and there was limited information reported on socioeconomic status. Only 3 (43%) study conducted formative work, and few (n=3, 43%) reported on acceptability. Only 1 (14%) study reported that materials were available in Spanish and English, and only 1 (14%) study used culturally tailored content. Additionally, 3 (43%) studies used strategies that considered social determinants of health.

CONCLUSIONS

To increase our understanding of the feasibility and effectiveness of technology-based obesity prevention strategies among Hispanic adolescents, there is a need for more feasibility studies that are theoretically grounded and comprehensively report on feasibility-related outcomes. Future studies should also leverage technology to simultaneously address multiple health behaviors beyond diet and physical activity. The result of this review can be used to guide the development of future technology-based obesity prevention strategies among Hispanic adolescents.

Adolescent Body Mass Index and Exposure to Peers with Overweight and Obesity: A Structural Equation Model Approach to Longitudinal Network Data

Purpose: Considerable evidence has shown that social networks influence a wide variety of health behaviors. This study investigates whether having friends with overweight/obesity in one's social network (network exposure) can predict changes in body mass index (BMI) throughout high school in a diverse urban population of students. Methods: Racially and ethnically diverse students from five high schools in Los Angeles County were surveyed at four time points throughout high school from 2010 to 2013 (N = 2091). Surveys included questions on students' social networks, demographics, and health-related information. BMI and weight categories were calculated for all students who provided height and weight information (∼50%). A latent growth curve model was used to assess the growth trajectory of BMI and the time-varying effect of network exposure to friends with overweight/obesity while controlling for demographic covariates. Results: Hispanic students had a significantly higher initial BMI compared with non-Hispanic students (p < 0.01). There was a significant positive slope for time on BMI growth (p < 0.01). Greater personal network exposure to friends with overweight/obesity was associated with a significant 0.65-point average increase in BMI (p < 0.05) at the first follow-up time point (T2) and a significant 0.62-point average increase in BMI (p < 0.01) at the last follow-up (T4) while controlling for covariates. Conclusions: Using structural equation modeling to understand the relationship between BMI and social networks, we found that increased network exposure to peers with overweight/obesity is associated with higher individual BMI, demonstrating that friendships may influence adolescents' weight status over time.

Nutrition Interventions Addressing Structural Racism: A Scoping Review

African Americans experience high rates of obesity and food insecurity in part due to structural racism, or overlapping discriminatory systems and practices in housing, education, employment, health care, and other settings. Nutrition education and nutrition-focused policy, systems, and environmental changes may be able to address structural racism in the food environment. This scoping review aimed to summarize the available literature regarding nutrition interventions for African Americans that address structural racism in the food environment and compare them to the "Getting to Equity in Obesity Prevention" framework of suggested interventions. An electronic literature search was conducted with the assistance of a research librarian encompassing 6 databases-MEDLINE, PyscINFO, Agricola, ERIC, SocINDEX, and ProQuest Dissertations & Theses. A total of 30 sources were identified detailing interventions addressing structural barriers to healthy eating. The majority of nutrition interventions addressing structural racism consisted of policy, systems, and/or environmental changes in combination with nutrition education, strategies focused on proximal causes of racial health disparities. Only two articles each targeted the "reduce deterrents" and "improve social and economic resources" aspects of the framework, interventions which may be better suited to addressing structural racism in the food environment. Because African Americans experience high rates of obesity and food insecurity and encounter structural barriers to healthy eating in the food environment, researchers and public health professionals should address this gap in the literature.
