Within-Family Variation in Obesity Economics and Human Biology 10,4 (December 2012): 333-339. Also: http://www.sciencedirect.com/science/article/pii/S1570677X1200069X Cohort(s): Children of the NLSY79 Publisher: Elsevier Keyword(s): Body Mass Index (BMI); Childhood; Obesity; Siblings; Weight We use data from the Children of the National Longitudinal Survey of Youth 1979 to document the degree to which childhood obesity varies among siblings. We find considerable differences in body weight between siblings with over half of the siblings differing by more than 20 age-specific percentiles in terms of the body mass index. Even among identical twins, there is an average BMI difference of 12 percentiles. This variation is important for the use of econometric approaches that involve sibling comparisons. |
