    • Abstract:
      Objectives. To evaluate a multicomponent obesity prevention intervention among diverse, low-income preschoolers. Methods. Parent–child dyads (n = 534) were randomized to the Now Everybody Together for Amazing and Healthful Kids (NET-Works) intervention or usual care in Minneapolis, MN (2012–2017). The intervention consisted of home visits, parenting classes, and telephone check-ins. The primary outcomes were adjusted 24- and 36-month body mass index (BMI). Results. Compared with usual care, the NET-Works intervention showed no significant difference in BMI change at 24 (–0.12 kg/m2; 95% confidence interval [CI] = −0.44, 0.19) or 36 months (–0.19 kg/m2; 95% CI = −0.64, 0.26). Energy intake was significantly lower in the NET-Works group at 24 (–90 kcal/day; 95% CI = −164, −16) and 36 months (–101 kcal/day; 95% CI = −164, −37). Television viewing was significantly lower in the NET-Works group at 24 (rate ratio = 0.84; 95% CI = 0.75, 0.93) and 36 months (rate ratio = 0.88; 95% CI = 0.78, 0.99). Children with baseline overweight or obesity had lower BMI in the NET-Works group than those in usual care at 36 months (–0.71 kg/m2; 95% CI = −1.30, −0.12). Hispanic children had lower BMI in the NET-Works group than those in usual care at 36 months (–0.59 kg/m2; 95% CI = −1.14, −0.04). Conclusions. In secondary analyses, NET-Works significantly reduced BMI over 3 years among Hispanic children and children with baseline overweight or obesity.
