Effects of Overweight on Risky Sexual Behavior of Adolescent Girls

We use data from The National Longitudinal Survey of Adolescent Health to estimate effects of adolescent girls' overweight on their propensity to engage in risky sexual behavior. We estimate single equation, two-stage, and sibling fixed-effects models and find that overweight or obese teenage girls are more likely than their recommended-weight peers to engage in certain types of risky sexual behavior but not others. The results from this study underscore the importance of using multifaceted and contemporary measures of risky sexual behavior and have implications for the health and well-being of adolescent girls.
