The purpose of this study was to conduct a qualitative evaluation of a behavioral intervention to prevent and treat childhood obesity in minority children. Using qualitative methods to augment ...understanding of intervention success may be one way to gain insight into the types of behavior change strategies that are most effective in childhood obesity interventions.
COACH was a randomized controlled trial of 117 Latino parent-child (ages 3–5) pairs in Nashville, TN that resulted in improved child BMI in intervention vs. control families at 1-year follow-up. All participant parents were invited to focus groups after the trial. Discussions were audiotaped, transcribed, and translated into English. A hierarchical coding scheme was generated, and qualitative analysis done using an inductive/deductive approach. Both theme saturation and consensus between the coders were achieved. Responses were compared between intervention and control groups.
We conducted seven focus groups with 43 participants. 4 themes emerged from the intervention group: 1) perceived barriers to health behavior change; 2) strategies learned to overcome perceived barriers; 3) behavioral changes made in response to the program; and 4) knowledge, skills, and agency for family health behaviors. 4 themes emerged from the control group: 1) a desire to engage in health behaviors without specific strategies; 2) common set of barriers to health behavior change; 3) engagement in literacy activities, including creative problem-solving strategies; and 4) changes made in response to study visits. Analysis of coded data showed the intervention increased healthy behaviors (e.g., fruit/vegetable consumption) despite barriers (e.g., time, cost, culture, family dynamics). Intervention participants described using specific behavior change strategies promoted by the intervention including: substituting ingredients in culturally-normative recipes; avoiding grocery shopping when hungry; and coping with inability to meet goals with acceptance and problem-solving. Control participants reported little success in achieving healthy changes for their family. Intervention participants described successful health behavior changes that were shared across generations and were maintained after the program. Intervention participants reported increased awareness of their own agency in promoting their health.
Qualitative evaluation of COACH provides a more detailed understanding of the intervention's quantitative effectiveness: child and adult health behaviors and personal agency were improved.
Our work brings together theories and methodologies from public health and the learning sciences to develop a culturally relevant community-based intervention aimed at promoting healthy childhood ...development. We present our approach to personalising a community-based family intervention to prevent childhood obesity that aims to enhance participants' agency. We argue that situating obesity within the individual's multi-layered context not only provides a more robust understanding of the causes, but also generates sustainable options for promoting healthy lifestyles. Our findings emphasise the importance of a situated approach to learning that leverages social systems as a key resource for better navigating the environmental, material and ideational infrastructures that support healthy lifestyles.

IMPORTANCE: Prevention of obesity during childhood is critical for children in underserved populations, for whom obesity prevalence and risk of chronic disease are highest. OBJECTIVE: To test the ...effect of a multicomponent behavioral intervention on child body mass index (BMI, calculated as weight in kilograms divided by height in meters squared) growth trajectories over 36 months among preschool-age children at risk for obesity. DESIGN, SETTING, AND PARTICIPANTS: A randomized clinical trial assigned 610 parent-child pairs from underserved communities in Nashville, Tennessee, to a 36-month intervention targeting health behaviors or a school-readiness control. Eligible children were between ages 3 and 5 years and at risk for obesity but not yet obese. Enrollment occurred from August 2012 to May 2014; 36-month follow-up occurred from October 2015 to June 2017. INTERVENTIONS: The intervention (n = 304 pairs) was a 36-month family-based, community-centered program, consisting of 12 weekly skills-building sessions, followed by monthly coaching telephone calls for 9 months, and a 24-month sustainability phase providing cues to action. The control (n = 306 pairs) consisted of 6 school-readiness sessions delivered over the 36-month study, conducted by the Nashville Public Library. MAIN OUTCOMES AND MEASURES: The primary outcome was child BMI trajectory over 36 months. Seven prespecified secondary outcomes included parent-reported child dietary intake and community center use. The Benjamini-Hochberg procedure corrected for multiple comparisons. RESULTS: Participants were predominantly Latino (91.4%). At baseline, the mean (SD) child age was 4.3 (0.9) years; 51.9% were female. Household income was below $25 000 for 56.7% of families. Retention was 90.2%. At 36 months, the mean (SD) child BMI was 17.8 (2.2) in the intervention group and 17.8 (2.1) in the control group. No significant difference existed in the primary outcome of BMI trajectory over 36 months (P = .39). The intervention group children had a lower mean caloric intake (1227 kcal/d) compared with control group children (1323 kcal/d) (adjusted difference, −99.4 kcal 95% CI, −160.7 to −38.0; corrected P = .003). Intervention group parents used community centers with their children more than control group parents (56.8% in intervention; 44.4% in control) (risk ratio, 1.29 95% CI, 1.08 to 1.53; corrected P = .006). CONCLUSIONS AND RELEVANCE: A 36-month multicomponent behavioral intervention did not change BMI trajectory among underserved preschool-age children in Nashville, Tennessee, compared with a control program. Whether there would be effectiveness for other types of behavioral interventions or implementation in other cities would require further research.

To test the effect of a culturally tailored, family-centered, short-term behavioral intervention on BMI in Latino-American preschool-aged children.
In a randomized controlled trial, 54 parent-child ...dyads were allocated to the intervention and 52 dyads were allocated to an alternative school-readiness program as the control condition. Parent-child dyads were eligible if the parent self-defined Latino, was at least 18 years old, had a 2- to 6-year-old child not currently enrolled in another healthy lifestyle program, had a valid telephone number, and planned on remaining in the city for the next 6 months. The Salud Con La Familia (Health with the Family) program consisted of 12 weekly 90-minute skills-building sessions designed to improve family nutritional habits and increase physical activity. Both programs were conducted in a community recreation center serving an urban neighborhood of mostly Spanish-speaking residents.
Forty-two percent of participating preschool-aged children were overweight or obese. Controlling for child age, gender, and baseline BMI, the effect of the treatment condition on postintervention absolute BMI was B = -0.59 (P < .001). The intervention effect seemed to be strongest for obese children.
A skills-building, culturally tailored intervention involving parent-child dyads changed short-term early growth patterns in these Latino-American preschool-aged children. Examining long-term effects would be a prudent next step.
To scale-out an experiential teaching kitchen in Parks and Recreation centres' after-school programming in a large urban setting among predominantly low-income, minority children.
We evaluated the ...implementation of a skills-based, experiential teaching kitchen to gauge programme success. Effectiveness outcomes included pre-post measures of child-reported cooking self-efficacy, attitudes towards cooking, fruit and vegetable preference, intention to eat fruits and vegetables and willingness to try new fruits and vegetables. Process outcomes included attendance (i.e., intervention dose delivered), cost, fidelity and adaptations to the intervention.
After-school programming in Parks and Recreation Community centres in Nashville, TN.
Predominantly low-income minority children aged 6-14 years.
Of the twenty-five city community centres, twenty-one successfully implemented the programme, and nineteen of twenty-five implemented seven or more of the eight planned sessions. Among children with pre-post data (n 369), mean age was 8·8 (sd 1·9) years, and 53·7 % were female. All five effectiveness measures significantly improved (P < 0·001). Attendance at sessions ranged from 36·3 % of children not attending any sessions to 36·6 % of children attending at least four sessions. Across all centres, fidelity was 97·5 %. The average food cost per serving was $1·37.
This type of nutritional education and skills building experiential teaching kitchen can be successfully implemented in a community setting with high fidelity, effectiveness and organisational alignment, while also expanding reach to low-income, underserved children.
In this article, we describe a personalized approach to meeting individual and community health needs that foregrounds relational learning. This article analyzes how relational approaches to learning ...expand participants' objectives and result in more enduring learning. We report on mixed methods data from interviews, focus groups, surveys, and goal setting and monitoring. Analyses reveal that relationships de confianza served as a central tool in supporting participants' agency to enact change across scales of practice to promote the health of themselves, their families, and their communities.
Competency-Based Approaches to Community Health (COACH) is a randomized controlled trial of a family-centered, community-based, and individually-tailored behavioral intervention for childhood obesity ...among Latino pre-school children. COACH focuses on improving personal agency for health behavior change by tailoring content to overcome contextual barriers. The intervention focuses on diet, physical activity, sleep, media use, and engaged parenting. The content is individually adapted based on routine assessments of competency in specific health behaviors using a mobile health platform and novel measurement tools developed by our team. In response to these regular assessments, health coaches provide tailored health behavior change strategies to help families focus on the areas where they decide to improve the most. The intervention consists of a 15-week group-based intensive phase, with weekly sessions delivered by health coaches in community centers. Following weekly sessions, a 3-month maintenance phase of the intervention consists of twice monthly coaching calls for participants to focus on individual health goals for their families.
The primary outcome of the trial is child body mass index trajectory over 1 year. Secondary outcomes include parent body mass index change, child waist circumference, child diet, child physical activity, and other psychosocial mediators of child health behavior change. The control arm consists of a school readiness intervention, delivered by the Nashville Public Library.
By applying a personalized approach to child behavior change, in the setting of both family and community, COACH aims to develop sustainable solutions for childhood obesity by supporting healthy childhood growth in low-income, minority preschool children.
Living near community recreation centers (CRC) is associated with increases in adolescent and adult physical activity, but the efficacy of efforts to increase use among Latino parents and young ...children is unknown. We hypothesized that Latino parent-child dyads with exposure to a CRC through culturally tailored programming would be more likely to use the facility for physical activity a year after programming ended than dyads living in the same geographic area who were not exposed to the programming.
Self-identified Latino parent-child dyads who had participated in a randomized controlled trial (RCT) of a culturally tailored healthy lifestyle program and completed a 12-month follow-up assessment constituted the "exposed" group (n = 66). The "unexposed" group included 62 parent-child dyads living in the same zip codes as the exposed group, all within a 5-mile radius of the CRC. Participants completed in-person structured interviews.
Approximately two-thirds of exposed parents reported more than monthly use of the CRC for themselves a year after programming ended, compared to one-third of unexposed Latino families with the same geographic access (χ(2) = 11.26, p < 0.01). Parents in the exposed group were four times more likely than the unexposed group to use the CRC with their children on a monthly basis (odds ratio = 4.18, p < 0.01).
CRCs that develop culturally tailored programs that invite Latino families inside can increase sustained CRC use for physical activity in this population at heightened risk for childhood obesity.
