A study published in Ethnicity & Health reveals that adverse childhood experiences (ACE) contribute significantly to heart disease among Black men and women, accounting for up to 1.9 million cases. Using data from the Behavioral Risk Factor Surveillance System (2019-2022) involving 30,746 participants, researchers identified seven classes of ACEs, including domestic violence, sexual violence, and household substance abuse. The study utilized latent class analysis and gender-stratified binary logistic regressions to assess the relationship between ACEs and heart disease. Findings indicate that both men and women face increased odds of heart disease with higher ACE exposures, particularly through sexual violence and household issues like drug use and mental illness. For women, exceeding two ACEs notably raised heart disease risk, while for men, the connection was stronger with physical or verbal abuse and household imprisonment. The results highlight the importance of considering ACE heterogeneity in understanding heart disease patterns and suggest a need for targeted screening and interventions to promote health equity among affected populations.
