Public health disparities refer to the differences in health outcomes and access to healthcare services among different population groups. These disparities can be based on factors such as race, ethnicity, socioeconomic status, gender, age, geography, and other social determinants of health. Research in this area aims to identify and address the root causes of these disparities in order to achieve health equity for all. This may involve studying the impact of systemic racism, income inequality, inadequate access to healthcare, and other social determinants on health outcomes. Public health disparities research also seeks to develop interventions and policies that can help reduce or eliminate these disparities and ensure that all individuals have equal opportunities to achieve optimal health and well-being. This research is crucial for promoting health equity and improving the overall health of populations.
