David Grant, director of the California Health Interview Survey (CHIS), discusses a study that reviews ten years of data on the health of young children, including survey questions on health insurance coverage, preschool attendance, obesity, how often parents read to their child, and more. The data covers the years 2003 to 2012, a period in which public health efforts for children focused on childhood obesity and improved nutrition, access to low-cost and free dental services, and the expansion of children's health insurance programs. How well did California do?
