Childhood Obesity and Unhappiness: The Influence of Soft Drinks and Fast Food Consumption

A growing body of literature has examined the determinants of childhood obesity, but little is known about children's subjective wellbeing. To fulfill this gap, this paper examines the effects of fast food and soft drink consumption on children's overweight and unhappiness. Using a nationwide survey data in Taiwan and estimating a simultaneous mixed equation system, our results generally suggest a tradeoff in policy implication. Fast food and soft drink consumption tend to be positively associated with children's increased risk of being overweight but they are also negatively associated with their degree of unhappiness. Current and future policy/program interventions that aim to decrease fast food and soft drinks consumption of children to reduce childhood obesity may be more effective if these interventions also focus on ways that could compensate the increase in degree of unhappiness among children.
