Sex differences in cardiovascular risk factors and quality of life among individuals with hypertension in Korea from 2013 to 2018: A cross-sectional cohort study.

As its prevalence increases and its association with cardiovascular disease and mortality is established, there is a need to improve prevention and management strategies for hypertension. Therefore, we aimed to compare differences in cardiovascular health status between men and women with hypertension defined by systolic blood pressure ≥140 mmHg and diastolic blood pressure ≥90 mmHg, and/or treatment with antihypertensive drugs. The association between cardiovascular health status and health-related quality of life was also evaluated. Additionally, a secondary analysis was performed on the cross-sectional data from 7306 adults with hypertension, ≥40 years of age between 2013 and 2018. Of this sample, 51.2% of patients were women from the Korean National Health and Nutrition Examination Survey. The seven Cardiovascular Health Metrics were used to quantify cardiovascular health status and the 5-dimensional European Quality of Life Questionnaire (EQ-5D) was used to evaluate health-related quality of life. A higher proportion of men than that of women was observed in the poor cardiovascular health score group [total score 0-7], with a higher proportion of women in the intermediate group [total score 8-10] and ideal group [total 11-14] (p<0.0001). The proportion of women in the EQ-5D index was higher than that of men in the poor and intermediate groups (p<0.0001), with no difference in the proportion of men and women in the ideal group (p = 0.1452). Furthermore, specific cardiovascular risk factors were different between men and women: women had lower physical activity level and higher prevalence of high cholesterol (≥200 mg/dl), and men had higher body mass indices and worse diet management. These findings indicate that prevention and management strategies for hypertension and cardiovascular health might need to differ for men and women to improve outcomes.
