For each of our time use variables, coefficients are about five to six times as large for the children of non-college-educated mothers compared to their peers, and the null results for the latter are likely at least partly due to more modest first-stage associations, which are near or under commonly proposed weak-instrument thresholds. ! In the realm of public health, small-scale RCT and other experimental studies could help uncover what mechanisms are at play in deconstructing causal pathways, while other research using observational data and quasi-experimental methodology can lend support to or undermine our findings. 2023 Mar 29;13(4):293. doi: 10.3390/bs13040293. While some work does offer experimental evidence of the effects of select activities using randomized control trials (RCT)for example, Loprinzi and Kane (2015)it is difficult to infer how routinized behaviors affect outcomes of interest solely based on interventions among carefully targeted respondent populations. /Subtype /Image Regular physical activity exerts beneficial effects on onset and progression of a number chronic diseases, well-being, and has positive effect to communities and societies.
