This report delves into the critical relationship between social determinants of health (SDH) and heart disease, particularly within the Australian context. It begins by defining cardiovascular disease (CVD) and its prevalence, including incidence and mortality rates, highlighting the disproportionate impact on various demographic groups. The report then explores key SDH, such as socioeconomic position, early life experiences, social exclusion, employment, and housing, illustrating how these factors influence an individual's health and increase the risk of heart disease. Furthermore, the report examines public health interventions, including community-based platforms and environmental considerations, aimed at mitigating the negative effects of SDH. It also references strategies like the Healthy People 2010 action plan and the American Heart Association's initiatives, emphasizing the need for comprehensive approaches to address health inequalities and improve heart health outcomes. The report concludes by summarizing the key findings and emphasizing the importance of understanding and addressing SDH to reduce the burden of heart disease in Australia.
