Policy Points A growing body of research suggests that policing, as a form of state-sanctioned racial violence, operates as a social determinant of population health and racial or ethnic health disparities. A lack of compulsory, comprehensive data on interactions with police has greatly limited our ability to calculate the true prevalence and nature of police violence. While innovative unofficial data sources have been able to fill these data gaps, compulsory and comprehensive data reporting on interactions with police, as well as considerable investments in research on policing and health, are required to further our understanding of this public health issue.

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.
