Abstract

BackgroundLatino preschool children have higher rates of obesity than preschool children from other racial/ethnic groups; however, few effective, culturally appropriate interventions exist targeting this group. The purpose of this study was to test the feasibility of a 10-week, promotora-mediated, home-based intervention to promote a healthy weight in Latino preschool children.MethodsTrained promotoras (community health workers) delivered 10, 90-min weekly interactive and tailored sessions to Latino families living in Allegheny County. Participants were recruited through promotoras’ own social networks and community gatherings, flyers, and word of mouth. Primary outcome measures included child body mass index (BMI) z-score and percentile. Secondary outcome measures included child objectively measured physical activity and dietary intake, and the home social and physical environment (e.g., parent health behaviors, parent self-efficacy, parental support, physical activity equipment in the home). The final analysis sample included 49 of 51 participants who completed both baseline and follow-up assessments.ResultsParticipants included mothers (33.5 ± 6.1 years old) and their preschool-aged children who were primarily 1st generation immigrants from Mexico (65%). The primary analyses of BMI percentile and z-score showed no change post-intervention. However, there was a significant decrease in child BMI percentile for overweight and obese children from baseline to follow-up (p < .05). We also saw significant pre/post increases in child daily fruit and vegetable intake, and parent moderate-to-vigorous physical activity, fruit and vegetable servings per day, and self-efficacy; and significant decreases in child saturated fat and added-sugar intake, and child and parent screen time (p’s < .05).ConclusionsDespite the short duration of the intervention and follow-up, this pilot study showed promising effects of a promotora-mediated intervention to promote a healthy weight in Latino preschool children.

Highlights

Latino preschool children have higher rates of obesity than preschool children from other racial/ ethnic groups; few effective, culturally appropriate interventions exist targeting this group
Despite the short duration of intervention and follow up, we saw significant pre/post improvements in both child and parent self-reported dietary intake and screen time, and parent physical activity. These findings suggest that a promotora-mediated intervention with Latino preschool children living in an emerging Latino community may be effective in improving both child and parent behaviors associated with excessive weight gain
In conclusion, there are clear disparities in child obesity for preschool-aged Latino children, and there is a lack of knowledge surrounding effective intervention approaches to promote a healthy weight this population

Summary

Introduction

Latino preschool children have higher rates of obesity than preschool children from other racial/ ethnic groups; few effective, culturally appropriate interventions exist targeting this group. 16.7% of Latino preschool children are considered obese compared with 3.5% of non-Latino white, 11.3% non-Latino black, and 3.4% of non-Latino Asian children [3]. This is troubling considering obesity tracks into adulthood and. As the U.S Latino population continues to increase, the public health need for effective, culturally-appropriate obesity interventions for Latino children escalates. Few effective healthy lifestyle interventions exist that target Latino preschool children [7, 8].
