Low income and education are associated with greater ASCVD risk scores among adults in the US.

Introduction: Social determinants of health (SDOH) are fundamental causes of poor cardiovascular health, yet cardiovascular disease (CVD) risk assessment tools exclude SDOH. Our objective was to determine whether SDOH are independently associated with CVD risk in US adults. Methods: Utilizing the National Health and Nutrition Examination Survey (NHANES), we combined years 1999-2018 and included participants aged 40-79 without history of CVD and with information to calculate CVD risk (n = 21,694). Ten-year risk of atherosclerotic CVD (ASCVD) was calculated using the American Heart Association/American College of Cardiology (AHA/ACC) pooled cohort equations. We used linear regression models to estimate the association between SDOH and ASCVD risk, after adjusting for demographic factors. All analyses accounted for the complex survey design. Results: Mean age was 54.7 years, with 52.7 % female, 73.8 % non-Hispanic White, 9.4 % non-Hispanic Black, and 10.7 % Hispanic. From adjusted models, compared with an income of ≥ $75 K, ASCVD risk was greater by 3.06 (95 % CI: 2.65, 3.47) among those with income < $25 K, by 1.55 (95 % CI: 1.21, 1.89) among those with income $25 K-<$55 K, and by 1.20 (95 % CI: 0.84, 1.56) among those with income $55 K-<$75 K. Compared to college graduates, ASCVD risk was greater by 3.09 (95 % CI: 2.56, 3.62) among those with less than a high school education, by 1.65 (95 % CI: 1.31, 200) among those who were high school graduates, and by 1.41 (95 % CI: 1.11, 1.72) among those with some college education. Conclusion: We found strong graded associations between lower income and lower educational attainment with greater CVD risk.

Length of Time in the United States and Cardiometabolic Outcomes Among Foreign and US-Born Black Adults.

INTRODUCTION: Among certain immigrant groups, length of time spent living in the United States (LOT) is associated with poor cardiometabolic health. We aimed to evaluate the association between LOT and cardiometabolic outcomes among US Black adults. METHODS: The National Health Interview Survey is an annual representative survey of non-institutionalized US civilians. We combined 2016-2018 data and included all Black adults (N = 10,034). LOT was defined as the number of years lived in the US, if foreign-born. Obesity, hypertension, diabetes, and high cholesterol were each self-reported. We used logistic regression models to determine whether LOT was associated with cardiometabolic health factors overall and by origin subgroups-US-born non-Hispanic, Hispanic, African-born, and Caribbean/Central American (CA)-born groups. RESULTS: Our study population was 81% US-born non-Hispanic, 5% Hispanic (both foreign- and US-born), 6% African-born, and 6% Caribbean/CA-born groups. Among Black adults, compared with the US-born, being foreign-born with < 15 years in the US was associated with lower odds of obesity (OR: 0.31, 95%CI: 0.23-0.42) and hypertension (OR: 0.35, 95%CI: 0.24-0.49). In subgroup analyses, Caribbean/CA-born individuals with < 15 years in the US had 64% lower odds of obesity (OR: 0.36, 95%CI 0.15-0.84) and 63% lower odds of hypertension (OR: 0.37, 95%CI 0.15-0.88) compared with those with ≥ 15 years. CONCLUSION: Shorter LOT was associated with more favorable cardiometabolic health, with differential associations among foreign-born Black adults based on origin. This heterogeneity suggests a need to examine the implications of acculturation in the context of the specific population of interest.
