Sex differences in the association between ideal cardiovascular health and biomarkers of cardiovascular disease among adults in the United States: a cross-sectional analysis from the multiethnic study of atherosclerosis.

ABSTRACT: OBJECTIVES:This study investigated the sex differences in the associations between ideal cardiovascular health (CVH), measured by the American Heart Association's Life's Simple 7 metrics, and cardiovascular disease (CVD)-related biomarkers among an ethnically diverse cohort of women and men free of clinical CVD at baseline. SETTING:We analysed data from the Multi-Ethnic Study of Atherosclerosis conducted in six centres across the USA (Baltimore, Maryland; Chicago, Illinois; Forsyth County, North Carolina; Los Angeles, California; New York, New York; and St Paul, Minnesota). PARTICIPANTS:This is a cross-sectional study of 5379 women and men, aged 45-84 years old. Mean age (SD) was 62 (10), 52% were women, 38% White, 11% Chinese American, 28% Black and 23% Hispanic. PRIMARY MEASURES:The seven metrics (smoking, body mass index, physical activity, diet, total cholesterol, blood pressure and blood glucose) were each scored as 0 points (poor), 1 point (intermediate) or 2 points (ideal). The total CVH score ranged from 0 to 14. The CVD-related biomarkers studied were high-sensitivity C-reactive protein, D-dimer, fibrinogen, homocysteine, high-sensitivity cardiac troponin T, N-terminal pro B-type natriuretic peptide (NT-proBNP) and interleukin 6. We examined the association between the CVH score and each biomarker using multivariable linear regression, adjusting for age, race/ethnicity, education, income and health insurance status. RESULTS:Higher CVH scores were associated with lower concentrations of all biomarkers, except for NT-proBNP where we found a direct association. There were statistically significant interactions by sex for all biomarkers (p<0.001), but results were qualitatively similar between women and men. CONCLUSION:A more favourable CVH score was associated with lower levels of multiple CVD-related biomarkers for women and men, except for NT-proBNP. These data suggest that promotion of ideal CVH would have similarly favourable impact on the reduction of biomarkers of CVD risk for both women and men.

Project description:BackgroundStudies demonstrate that women physicians are less likely than men to be full professors. Comprehensive evidence examining whether sex differences in faculty rank exist in academic cardiology, adjusting for experience and research productivity, is lacking. Therefore, we evaluated for sex differences in faculty rank among a comprehensive, contemporary cohort of US cardiologists after adjustment for several factors that impact academic advancement, including measures of clinical experience and research productivity.MethodsWe identified all US cardiologists with medical school faculty appointments in 2014 by using the American Association of Medical Colleges faculty roster and linked this list to a comprehensive physician database from Doximity, a professional networking website for doctors. Data on physician age, sex, years since residency, cardiology subspecialty, publications, National Institutes of Health grants, and registered clinical trials were available for all academic cardiologists. We estimated sex differences in full professorship, adjusting for these factors and medical school-specific fixed effects in a multivariable regression model.ResultsAmong 3810 cardiologists with faculty appointments in 2014 (13.3% of all US cardiologists), 630 (16.5%) were women. Women faculty were younger than men (mean age, 48.3 years versus 53.5 years, P<0.001), had fewer total publications (mean number: 16.5 publications versus 25.2 publications; P<0.001), were similarly likely to have National Institutes of Health funding (proportion with at least 1 National Institutes of Health award, 10.8% versus 10.4%; P=0.77), and were less likely to have a registered clinical trial (percentage with at least 1 clinical trial, 8.9% versus 11.1%; P=0.10). Among 3180 men, 973 (30.6%) were full professors in comparison with 100 (15.9%) of 630 women. In adjusted analyses, women were less likely to be full professors than men (adjusted odds ratio, 0.63; 95% confidence interval, 0.43-0.94; P=0.02; adjusted proportions, 22.7% versus 26.7%; absolute difference, -4.0%; 95% confidence interval, -7.5% to -0.7%).ConclusionsAmong cardiology faculty at US medical schools, women were less likely than men to be full professors after accounting for several factors known to influence faculty rank.
