A cohort study is the best choice as it describes a specific group of individuals who share a characteristic of interest and are followed over time to observe a health outcome. This type of study is useful for identifying potential risk factors or associations between exposures and outcomes. Case control studies are retrospective and compare a group of individuals with a specific health outcome (cases) to a group without the outcome (controls), often to identify potential risk factors. Cross-sectional studies involve collecting data at a single point in time from a representative sample of individuals, while experimental studies involve randomly assigning individuals to a treatment or control group to test the effect of an intervention or exposure.
