This chapter discusses various economic factors such as food prices and food-related outlet availability and their relation to child body weight outcomes. It provides empirical evidence on the extent to which fiscal policy interventions can be expected in the area of food pricing or other interventions that reduce the relative cost of obtaining healthy foods by, for example, increasing access to outlets such as supermarkets, to improve weight outcomes among U.S. children. It examines whether the relationships between child weight and food prices and food-related outlet availability differ by households' socioeconomic status (SES) by examining differences in estimates by household income. Higher fruit and vegetable prices were statistically significantly related to a higher BMI percentile ranking among children, with larger effects for children in low-SES families. The fruit and vegetable price elasticity for BMI percentile ranking was estimated to be 0.25 for the full sample, and 0.60 among low-income children.

Keywords: food prices; child body weight; socioeconomic status; food price; food outlet
