Health disparities refer to preventable differences in health outcomes among various populations, often influenced by social, economic, and environmental factors. These disparities can result from unequal access to healthcare, differences in education, income inequality, geographic location, and systemic biases. Addressing health disparities requires understanding the root causes of inequities, implementing policies to improve access to care, and fostering community engagement. Professionals in this field work to reduce disparities through research, advocacy, and the development of programs aimed at improving healthcare accessibility and outcomes for marginalized populations.
