Childhood obesity prevention from cell to society.

Nearly 40% of US children are overweight or obese. We propose that a cell-to-society integrative approach is needed that takes into account biology, early child development, home and childcare environments, and public policy. This approach requires researchers, families, and policy makers to work together to develop preventative strategies and interventions that benefit the nutrition and wellbeing of young children and their families, and ultimately the health of the nation.
