Health disparities among different socioeconomic groups have been a longstanding issue in healthcare systems worldwide. This review article aims to explore the various factors contributing to these disparities and their significant impact on healthcare outcomes. Socioeconomic status plays a crucial role in determining access to healthcare services, quality of care received, and ultimately, health outcomes. Low-income individuals and marginalized populations often face barriers such as limited access to healthcare facilities, lack of health insurance, and inadequate resources for preventive care. These disparities result in higher rates of chronic diseases, poorer health outcomes, and increased healthcare costs. The review will delve into the complex interplay of social determinants of health, including income, education, employment, and housing, and their influence on health disparities. It will examine how these factors create inequities in healthcare access, utilization, and outcomes among different socioeconomic groups. Additionally, the article will discuss the role of healthcare policies, cultural factors, and systemic discrimination in perpetuating these disparities. Furthermore, the review will highlight interventions and strategies aimed at reducing health disparities and improving healthcare outcomes for disadvantaged populations. These may include targeted public health programs, community-based initiatives, and policy reforms to address the root causes of socioeconomic disparities in healthcare. By addressing these disparities, healthcare systems can promote health equity and ensure that all individuals have equal opportunities to achieve optimal health outcomes.
