The effect of body weight on adolescent sexual activity
研究利用美国青少年健康纵向调查数据，发现体重增加会降低女性青少年开始性行为的概率，但对男性青少年没有显著影响。
Recent research suggests that overweight females suffer penalties in the labor and marriage markets, while overweight males do not. This study explores whether similar gender differences in the effect of body weight exist in what Cawley et al. (2006) labeled 'the adolescent sex market'. Drawing on data from the National Longitudinal Study of Adolescent Health, we use fixed effects and instrumental variables identification strategies to estimate the relationship between body weight and sexual activity. We find evidence that increased body weight lowers the probability that female adolescents become sexually active. In contrast, there is little evidence of a causal relationship between body weight and sexual activity for male adolescents.
