Hispanic Overweight and Obese Children

Abstract

Through Value Enhanced Nutrition Assessment and other techniques, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) engages clients to set their own nutrition goals. A case series of 30 Hispanic children (2-4.5 years) at ≥85th body mass index (BMI) percentile and their caregivers were followed through an urban WIC clinic. The dyads received either standard counseling ( n = 15) or motivational interviewing (MI; n = 15) by one bilingual WIC nutritionist during 4 regularly scheduled visits over 6 months. Repeated measurements of anthropometric data, dietary patterns, and physical activity were obtained at each visit. Longitudinal bivariate analyses of caregiver concerns and goal selection were conducted along with mean comparisons of anthropometric and food frequency measures. Participation in counseling sessions as rated by the nutritionist was assessed by comparing Wilcoxon rank-sum scores. After counseling, children lost an adjusted mean weight of 0.878 kg (95% confidence interval = 0.280-1.717). A decline in median BMI of more than 3 percentiles ( P = .042) was observed with both counseling approaches. Caregiver-reported vegetable intake of children increased an average of one additional serving in the MI-counseled group by visit 3 ( P = .013) despite MI recipient caregivers being scored as significantly more distracted than standard WIC participants in the first visit ( P = .036). MI is a viable option for WIC counseling to improve diet and health outcomes in participants, particularly in addressing child BMI status and vegetable intake. Public health professionals should examine scalability of the MI approach among larger samples of WIC participants and other innovative techniques to improve client focus during counseling.
