With rapid economic growth, China has witnessed the epidemic of childhood overweight and obesity. This paper contributes to this line of empirical study by employing switching regression model to study two groups of children: those who patronize fast food and those who do not. Moreover, we estimate and compare the counterfactual weights of children in each of the two categories. Using the data from 2006 China Health and Nutrition Surveys (CHNS), we verify the positive impact of fast food consumption on children's BMI and also find that children's self-selection on fast food consumption affects two groups of children unevenly.
