The intergenerational transmission of body mass index across countries

Abstract: There is a worldwide epidemic of obesity. We are just beginning to understand its consequences for child obesity. This paper addresses one important component of the crisis; namely the extent to which adiposity, or more specifically, BMI, is passed down from one generation to the next. We find that the intergenerational elasticity of BMI is very similar across countries and relatively constant – at 0.2 per parent. Our substantive finding is that this elasticity is very comparable across time and countries – even if these countries are at very different stages of economic development. Quantile analysis suggests that this intergenerational transmission mechanism is substantively different across the distribution of children’s BMI; more than double for the most obese children what it is for the thinnest children. These findings have important consequences for the health of the world’s children.11We wish to thank Oscar Marcenaro-Gutierrez, Alma Sobrevilla and Qisha Quarina for preliminary research assistance on the Spanish, Mexican and Indonesian data respectively.
