Do All Activities “Weigh” Equally? How Different Physical Activities Differ as Predictors of Weight

In Britain, it is recommended that, to stay healthy, adults should do 150 minutes of moderate‐intensity physical activity every week. The recommendations provided by the U.K. government, however, remain silent in regard to the type of activity that should be done. Using the annual Health Survey for England we compare how different types of physical activities predict a person's weight. In particular, we consider clinically measured body mass index and waist circumference. We document mean slopes emanating from ordinary least squares regressions with these measures as the dependent variables. We show that individuals who walk at a brisk or fast pace are more likely to have a lower weight when compared to individuals doing other activities. Additionally, we highlight that the association between physical activity and weight is stronger for females and individuals over the age of 50. Our overall conclusions are robust to a number of specifications.     

Make Time for Physical Activity or You May Spend More Time Sick!

This work estimates the association between various types of physical activities and physical health, mental health and health service utilization. Specifically, we consider participation in housework, manual, walking, sports/exercise and total physical activities to a moderate level. We view this as an important contribution given that governments usually recommend a total level of activity that their citizens should achieve to be healthy, rather than a particular activity per se. Our results suggest that participation in any of these activities predicts a lower probability of poor health roughly to the same level. For mental health, our estimates highlight that those who participate in (and do more of) any activity have better mental health when compared to those who do not. The associations are higher for women. The associations are also higher for manual activities and sports/exercise when compared to other activities. The analysis also reveals some lower utilization of in-patient, out-patient visits and GP services among individuals who are moderately physically active.
