Social determinants of cardiovascular disease in women with and without breast cancer
摘要
Social determinants of health (SDOH) may impact cardiovascular (CV) risk in women with and without breast cancer (BC).
MethodsIn 153,401 participants without prevalent CV disease from the Women’s Health initiative (WHI), we assessed key SDOH factors: geographic region, rurality, insurance status, and household income. Multivariable Cox proportional hazards models were used to assess associations between SDOH factors and a composite CV outcome, which included incident myocardial infarction, incident stroke, hospitalization for heart failure, or CV death.
ResultsIn the final cohort, 10,954 (mean ± standard deviation [SD] age 62 ± 7 years) women developed BC, and 142,144 (mean age 63 ± 7 years) women remained free of BC. During a median follow-up time of 13 years, 18,148 women experienced the composite CV outcome. Rurality, low household income, and non-private insurance were associated with an increased risk of the composite CV outcome and CV death, both in women with and without BC.
ConclusionsSDOH factors are associated with an increased risk of CV events among women, irrespective of BC status. These associations highlight the importance of socioeconomic factors across cardiovascular health outcomes.
