Neighborhood Disadvantage Accelerates Cardiovascular Decline in Midlife Women, Two-Decade Study Finds
核心洞察
Women in the most socially vulnerable neighborhoods scored 6 to 10 points lower on cardiovascular health measures over two decades compared to those in the least disadvantaged areas.
Heart health disparities emerged as early as three years into the study and persisted into midlife, with faster declines observed in the years leading up to menopause.
The association between neighborhood conditions and heart health held even after accounting for income and education, suggesting environmental factors independently shape cardiovascular risk.
A woman's neighborhood may influence her heart health for decades, according to new research published in Circulation: Population Health and Outcomes that found social and environmental conditions can be as consequential as personal habits and genetics when assessing cardiovascular risk.
The study, led by the Harvard Pilgrim Health Care Institute (搜索), followed approximately 1,200 women in eastern Massachusetts for more than 20 years, from pregnancy through midlife. Researchers measured heart health at five separate time points using a composite score built from eight health and lifestyle factors, including blood pressure, cholesterol, sleep, diet, and physical activity.
"What is striking is that women living in socially vulnerable neighborhoods did not just start with worse cardiovascular health—they lost ground faster, especially before menopause even began," said Dr. Miles Varn, chief medical officer for Sun Life U.S. (搜索) "That is a call to screen for social and neighborhood risk factors alongside traditional ones, and to intervene earlier than we typically do."
Persistent Disparities Across Two Decades
Women in the most socially vulnerable neighborhoods scored roughly six to 10 points lower on heart health measures than women in the least disadvantaged areas. These differences were evident as early as three years after enrollment and persisted into midlife. The gap was accompanied by faster declines in cardiovascular health during the years leading up to menopause, a stage of life already linked to rising cardiovascular risk.
Socioeconomic factors also shaped outcomes. Women with lower income, less education, or who identified as non-Hispanic Black had lower heart health scores throughout the study period.
Notably, the connection between neighborhood conditions and heart health held up even after researchers accounted for income and education separately. Women who spent years living in highly vulnerable neighborhoods showed consistently lower scores and steeper declines in heart health over time.
Clinical Significance of Modest Score Differences
Because heart disease remains the leading cause of death among women, the study's authors emphasize that even small differences in heart health scores carry meaningful clinical implications. Prior research has linked modest drops in these scores to a higher risk of both cardiovascular disease (搜索) and death, suggesting the disparities identified in this study could have lasting consequences.
"Our study shows that heart health in midlife is shaped by more than personal choices. Income, education, and neighborhood conditions may all play a role," said senior author Izzuddin Aris, Harvard Medical School associate professor at the Harvard Pilgrim Health Care Institute (搜索).
Implications for Prevention and Intervention
The findings point to potential solutions, including improving access to healthy food, safe places to exercise, and quality health care in disadvantaged communities. Aris added that "the years before and around menopause may be an important time to support women's heart health," particularly "for women living in under-resourced neighborhoods."
Dr. Varn underscored the broader implications: "If we want to close that gap, we cannot just treat the individual patient, we need to address the conditions in their community too."
The research drew on Project Viva, a long-running study that has tracked women since pregnancy in the early 2000s through midlife. That two-decade span of repeated health data allowed researchers to identify long-term patterns that shorter studies might miss, providing a uniquely comprehensive view of how neighborhood vulnerability shapes cardiovascular trajectories over time.
