Quizplus · Accepted Answer

A cohort study would be the best choice to investigate whether cigarette smoking influences weight gain since it allows for the comparison of groups with and without exposure to the risk factor (in this case, cigarette smoking) over a period of time to observe the development of the outcome (in this case, weight gain). This can help determine whether there is a causal relationship between cigarette smoking and weight gain. Conventional studies may not provide enough information on the temporal relationship between smoking and weight gain, while double-blind and single-blind studies are not relevant for this type of investigation.
