INTRODUCTION: This article explored the relationship between physical activity and smoking behavior among adolescents using rich longitudinal survey data from a nationally representative sample of adolescents.
METHODS: Several endogeneity-corrected models were estimated to ascertain the effect of exercise on both the probability of being a smoker and the intensity of cigarette smoking.
RESULTS: The analysis indicated that 1 additional weekly occurrence of exercise led to a 0.3% decline in the probability of being a smoker and led to a 4.1% reduction in the number of cigarettes smoked by a smoker during a month, a result that was robust to stratification by gender and race/ethnicity. Consistent with the national guidelines, frequencies of physical activity of at least 7 times per week appeared to exhibit the biggest benefits in terms of reduction in smoking for both genders and across races/ethnicities.
CONCLUSIONS: Reduction in health-damaging smoking behavior among adolescents could be an additional benefit of being physically active. This research documented a new pathway by which even moderate increases in physical activity could result in improved health outcomes by reducing smoking.
