This paper examines how the obesity status of different children within the same family is related to a parent or sibling’s obesity. Analyzing results of a 2011 national survey of adults in 10,244 U.S. households, researchers found that the likelihood of childhood obesity varied with the number of children in a household, as well as their gender. In a single-child household, a child was 2.2 times more likely to be obese if a parent was obese. In households with two children, for the elder child, having an obese parent was associated with a 2.3 times greater likelihood of child obesity, and having an obese younger sibling was associated with a 5.4 times greater obesity likelihood. For a younger sibling in a two-child household, having an obese parent was not significantly related to obesity, but having an obese older sibling was associated with a 5.6 times greater likelihood of younger sibling obesity. Within-family sibling obesity was more strongly patterned between siblings of the same gender than between genders. For younger boys in two-child families, obesity was 11.4 times more likely with a male older sibling; and for younger girls in two-child families, obesity was 8.6 times more likely with a female older sibling.

Examining the Effects of In-Store Marketing on the Purchase of Excess, Non-Nutrient Calories and on Childhood ObesityThe impact of family food purchasing on child obesity is understudied, and little is known about the roles that consumer shopping behavior and local prices for goods with different nutritional content play in determining obesity prevalence. This project will use unique, nationally-representative scanned UPC data collected by Nielsen over a 12-year period on consumer grocery More
