Elementary school children in communities with high produce prices are more likely to gain weight than those areas with low produce costs, according to a study published in Public Health. The study, Food Prices and Weight Gain During Elementary School: 5-year Update, showed that children who lived in the 15 areas where fruits and vegetables were most expensive (relative to cost-of-living) gained 4 pounds more between kindergarten and fifth grade than children living in the 15 areas where fruits and vegetables were least expensive.
