Has overweight become the new normal?: evidence of a generational shift in body weight norms
Nadler, Carl; Heiland, Frank; Burke, Mary A. (2009)
We test for differences across the two most recent NHANES survey periods (1988?1994 and 1999?2004) in self-perception of weight status. We find that the probability of self-classifying as overweight is significantly lower on average in the more recent survey, for both men and women, controlling for objective weight status and other factors. Among women, the decline in the tendency to self-classify as overweight is concentrated in the 17?35 age range, and, within this range, is more pronounced among women with normal BMI than among those with overweight BMI. Among men, the shift away from ...

Explaining gender-specific racial differences in obesity using biased self-reports of food intake
Heiland, Frank; Burke, Mary A. (2011)
Policymakers have an interest in identifying the differences in behavior patterns - namely, habitual caloric intake and physical activity levels - that contribute to demographic variation in body mass index (BMI) and obesity risk. While disparities in mean BMI and obesity rates between whites (non-Hispanic) and African-Americans (non-Hispanic) are well-documented, the behavioral differences that underlie these gaps have not been carefully identified. Moreover, the female-specificity of the black-white obesity gap has received relatively little attention. In the National Health and Nutrition ...

Social dynamics of obesity
Heiland, Frank; Burke, Mary A. (2006)
In order to explain the substantial recent increases in obesity rates in the United States, we consider the effect of falling food prices in the context of a model involving endogenous body weight norms and an explicit, empirically grounded description of human metabolism. Unlike previous representative agent models of price-induced gains in average weight, our model, by including metabolic heterogeneity, is able to capture changes in additional features of the distribution, such as the dramatic growth in upper-quartile weights that are not readily inferred from the representative agent ...

Working Paper
Race, obesity, and the puzzle of gender specificity
Heiland, Frank; Burke, Mary A. (2008)
Obesity is significantly more prevalent among non-Hispanic African-American (henceforth ?black?) women than among non-Hispanic white American (henceforth ?white?) women. These differences have persisted without much alteration since the early 1970s, despite substantial increases in the rates of obesity among both groups. Over the same time period, however, we observe little to no significant differences in the prevalence of obesity between black men and white men. Using data from the National Health and Nutrition Examination Surveys (NHANES) and the Behavioral Risk Factor Surveillance System ...
