La Vida Buena (The Good Life) evaluation: a quasi experimental intervention of a community health worker-led family-based childhood obesity program for Latino children 5-8 years of age on the US-Mexico border

Using the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) Framework to Evaluate a Tailored Education Program to Reduce Obesity-Related Cancers in El Paso, Texas

Background: Pasos Para Prevenir Cancer is a tailored lifestyle program that focuses on behavioral modification through knowledge and behavioral strategy education, which was delivered in El Paso, Texas, on the U.S.-Mexico border. Methods: Using the RE-AIM framework, we assessed Pasos Para Prevenir Cancer for efficacy and potential for sustainability. Survey, administrative, and observational data were collected between 2018 and 2022. The program was evaluated to determine reach, effectiveness, adoption, implementation, and maintenance. Results: Tailoring and adapting to the U.S.-Mexico border context is feasible and necessary to deliver evidence-based healthy eating and active living education content. Pasos Para Prevenir Cancer was well received and delivered in diverse settings with varying linguistic needs. Components of the program were adopted by other organizations and integrated into existing programming. Conclusions: Adapting and tailoring evidence-based programs to improve healthy eating and active living is required to meet the needs of Latino subgroup populations, like those on the U.S.-Mexico border.

Results From La Vida Buena (The Good Life): A Quasi-Experimental Intervention of a Community Health Worker-Led Family-Based Childhood Obesity Program for Latino Children 5-8 Years of Age on the U.S.-Mexico Border

OBJECTIVE

To evaluate the effectiveness of the 8-week, community health worker (CHW)-led La Vida Buena childhood obesity program among Latino children 5 to 8 years old in a rural county along the U.S.-Mexico border.

METHODS

This quasi-experimental study used a community-based participatory research approach to compare the effectiveness of the La Vida Buena (The Good Life) curriculum as compared with a single educational session. We took anthropomorphic measures and administered parent-reported nutrition and physical activity surveys at baseline, 3 months, and 6 months. The study took place between 2017 and 2020 in Santa Cruz County, Arizona.

RESULTS

Change in body mass index (BMI) z-score was negligible for both groups. The parent-reported behavior indicated a shift toward healthier family behaviors and environment in the intervention group.

IMPLICATIONS FOR PRACTICE

This study adds to the growing literature of CHW-led childhood obesity interventions. The engagement of the CHWs in all aspects of the intervention helped to facilitate important behavior changes. Future interventions should emphasize health and wellness rather than BMI z-score and include community, socioeconomic, and systems-level interventions to promote healthy environments.

Nutrition Effects of a Family-Centered Health Promotion Program for Mexican-Heritage Children in the Lower Rio Grande Valley of Texas

Systemic and social factors, like poverty and food insecurity, negatively influence fruit and vegetable (FV) intake and body mass index (BMI) among Latino/a children. Behavioral programs are needed to support children’s nutrition. This study examined program effects on FV intake and BMI outcomes for Mexican-heritage children (9–11 years). The program used a modified stepped-wedge design in the Lower Rio Grande Valley of Texas (2019 and 2020). Promotoras led experiential nutrition education sessions and collected height, weight, and instant skin carotenoid scores (biomarker for FV intake) at pre-test (baseline), post-test (6 weeks), and maintenance (3–4 months after post-test). Mean changes and group differences in skin carotenoid scores, BMI z-scores and percentiles were obtained from analyses of variance. Linear mixed-effects models were used to determine overall program effects. Mexican-heritage children were enrolled (n = 57 and 52.6% female). An overall decrease in skin carotenoid scores was observed at post-test (−15.1; 95% CI: −24.95, −5.33). While scores varied widely (range: 17–498), an increase of 14.8 ± 23.8 points occurred in one intervention group. Compared to the control period, greater reductions in BMI outcomes occurred during the program. These findings provide evidence for the use of strengths-based approaches in behavioral nutrition programs.

Brazilian Immigrant Parents' Preferences for Content and Intervention Modalities for the Design of a Family-Based Intervention to Promote Their Preschool-Age Children's Healthful Energy Balance-Related Behaviors

Brazilians are a rapidly growing ethnic immigrant population in the United States (U.S.), and there is a lack of childhood obesity prevention interventions addressing the needs of Brazilian preschool-age children. Using the family ecological model (FEM) as a guide, this developmental cross-sectional study assessed the preferences (content, intervention modality, and language) of 52 individual Brazilian immigrant parents (27 mothers, 25 fathers) for a family-based intervention to promote healthful energy balance-related behaviors (EBRB). Overall, 85% or more of parents reported being interested or very interested in content related to five of the seven assessed EBRBs (increasing fruits and vegetables, reducing unhealthy foods and sugar-sweetened beverages, increasing physical activity, and reducing screen time). Parent-preferred intervention modalities were group sessions delivered by community health workers (CHWs, 86.5%), email (84.6%), and messaging (78.8%), with most parents (71.2%) indicating a preference for content in Portuguese. Interventions integrating multiple components, such as group sessions offered by CHWs and text messaging using SMS and WhatsApp, should be considered. Future steps for intervention development should include investigating different communication channels and their integration into a culturally and linguistically tailored family-based intervention designed to promote healthful EBRBs of preschool-age children in Brazilian families living in the U.S.

Central American Parents' Preferences for Content and Modality for a Family-Centered Intervention to Promote Healthful Energy Balance-Related Behaviors of Their Preschool-Age Children

This formative research used a cross-sectional survey to assess interest in informational content and intervention modalities for the design of an early childhood obesity prevention intervention for Central American families from the Northern Triangle countries (El Salvador, Guatemala, and Honduras) living in the United States. A total of 74 parents (36 mothers, 38 fathers) with a mean age of 31.6 years (SD = 5.6) completed the survey; 59.5% of whom were born outside of the United States. Although most parents reported being very interested in receiving information related to the seven assessed energy balance-related behaviors, there were significant differences by parents' gender and nativity. Most parents endorsed remote modalities for content delivery via text/SMS, WhatsApp, and e-mail. However, respondents were also receptive to in-person delivery provided by community health workers. There were also significant differences in parents' preferences for intervention modalities by parents' gender and nativity. Future steps should include investigating different intervention modalities and their integration into a linguistic and culturally sensitive family-based intervention to promote healthful energy balance-related behaviors of preschool-age children in Central American families originating from the Northern Triangle countries.

Pediatric Obesity Prevention and Treatment Among Hispanics: A Systematic Review and Meta-Analysis

INTRODUCTION

The rates of pediatric obesity in the U.S. are highest among Hispanics. There is no existing meta-analysis of the effects of obesity interventions among Hispanic youth. This systematic review and meta-analysis assesses the effects of obesity prevention and treatment interventions on Hispanic youth's weight status and lifestyle behaviors.

METHODS

PubMed, PsycINFO, and Scopus were searched between January 1, 2000 and October 30, 2020. Interventions with ≥50% Hispanic youth aged 0-18 years were included. Using a weighted inverse-variance procedure, fixed-effects and random-effects models were run for an overall effect size on the basis of the Qtotal test statistic. Hedges' g was calculated for outcomes of interest between baseline and postintervention separately for studies with multiple versus single conditions. Continuous and categorical moderators were also examined.

RESULTS

A total of 1,103 articles were screened, of which 117 were included in the narrative synthesis and 105 in the meta-analysis (n=49,276 youth). The overall effects for RCT/quasi-experimental studies on BMI status (g= -0.15, SE=0.03, 95% CI= -0.20, -0.10), waist circumference (g= -0.15, SE=0.10, 95% CI= -0.35, -0.05), physical activity (g=0.12, SE=0.05, 95% CI=0.03, 0.22), fruit and vegetable intake (g=0.08, SE=0.02, 95% CI=0.03, 0.12), and sugar-sweetened beverage intake (g= -0.07, SE= 0.03, 95% CI= -0.13, -0.01) were small. Intervention effects varied by participant developmental stage, SES, study setting, and lifestyle behavior target.

DISCUSSION

Beyond developing more impactful interventions to address obesity among Hispanic youth, findings highlight the need for targeted policies and more easily disseminable interventions that can spread small effects across a population for maximal public health impact.

Cultural adaptation of 'Healthy Dads, Healthy Kids' for Hispanic families: applying the ecological validity model

Background

Healthy Dads Healthy Kids (HDHK) is a unique lifestyle obesity intervention for fathers and children that demonstrated weight loss among the fathers and behavior change among fathers and children in Australia. The program is gender-tailored to specifically target fathers for weight loss and 5–12 year old children for obesity prevention. The aim of this formative study was to examine an Expert Panel’s and Hispanic Family Panel’s perceptions about the program and suggestions for the cultural adaptation of HDHK for Hispanic families in southwestern US.

Methods

Forty-four Hispanic participants (22 fathers, 13 mothers and 9 children) made up the Family Panel. They participated in 1–5 study contacts (focus groups, online survey, and/or interviews). The scripts and qualitative guides assessed participants’ perceptions of the HDHK content and material using the Ecological Validity Model. Studies were conducted in English or Spanish, depending on the preference of the participant. Focus groups and interviews were audio-recorded, transcribed, translated, and thematically coded. Findings were reviewed with the Expert Panel who helped inform the cultural adaptation.

Results

80% of parents were foreign-born, 57% spoke only Spanish at home, and 60% did not graduate from high school. Several themes emerged to inform the cultural adaptation of the program. Parents agreed with the HDHK goals and recommended the program place greater emphasis on parenting and limiting children’s screen time. Some mothers and fathers wanted greater mother engagement. Weekly videos and a Facebook group emerged as favorite alternative options to engage mothers. Greater promotion of familism (inclusion and impact on whole family) was recommended for the program goals and activities. Gender roles for mothers and fathers, and differences in how fathers interact with male and female children, emerged and should be considered in program activities. Several barriers to father engagement surfaced, including lack of time due to work schedules, physically demanding jobs, concerns of caring for children without mother, fathers’ current fitness/weight, and lack of knowledge of how to eat more healthfully. The reading level of the HDHK materials was too high for some parents.

Conclusion

Findings from these formative qualitative studies informed the cultural adaptation of HDHK for Hispanic families, to account for literacy level, cultural values, and barriers to participation and engagement.
