Obesity prevalence varies significantly across different socioeconomic and demographic groups, highlighting the impact of social determinants of obesity & health disparities. Limited access to healthy foods, safe physical activity spaces, and affordable healthcare disproportionately affects low-income populations, contributing to higher obesity rates. Education levels and occupational factors also influence dietary choices and lifestyle habits. Structural inequalities, including food deserts and marketing of unhealthy products in marginalized communities, exacerbate the problem. Additionally, cultural attitudes toward body weight and stigma associated with obesity influence health behaviors. Addressing these disparities requires policy-driven approaches, such as subsidizing nutritious foods, improving urban infrastructure, and integrating obesity care into primary healthcare. A deeper understanding of the social and environmental influences on obesity can drive more equitable and effective interventions.
