The content section presents statistics and discusses the impact of obesity on healthcare, the economy, and the quality of life for Indigenous children. The analysis delves into the role of social inequality, government policies, and socioeconomic factors in exacerbating the problem. The essay then explores the fundamental cause theory, which explains how socioeconomic factors are key determinants of illness, and structural-functionalism, which views healthcare as a social institution that maintains health and well-being. A critical sociological analysis highlights the power dynamics and stratification systems within Canadian society that affect access to resources and programs for Indigenous communities. The essay concludes by reiterating the need for policies and programs to promote healthy behaviors and address the existing disparities between Indigenous and non-Indigenous schools.
