What role do genetics play in health disparities?

Genetics play a crucial role in understanding health disparities as they can indeed influence an individual's susceptibility to various health conditions, but this influence does not operate in isolation. Instead, genetics are just one piece of a much larger puzzle. They interact with a host of other factors, including socioeconomic status, environment, lifestyle choices, and access to healthcare, which are all essential in shaping health outcomes.

For instance, certain populations may carry genetic predispositions that increase their risk for specific diseases; however, without factors such as adequate healthcare access, nutritious food, and healthy living environments, the expression of these genetic predispositions could be exacerbated or mitigated. This multifaceted interplay underscores the importance of viewing health outcomes through a comprehensive lens that accounts for both genetic factors and the social determinants of health, enhancing our understanding of why disparities exist within and between populations.
