Sex disparities in cardiovascular health metrics among rural-dwelling older adults in China: a population-based study

Abstract

Background Cardiovascular health (CVH) metrics among Chinese older adults are poorly understood. We investigated sex disparities in CVH metrics and their management among rural-dwelling older adults in China. Methods This community-based study included 5026 participants (age ≥ 65 years; 57.2% women) in the baseline survey of a multimodal intervention study in rural China. In March–September 2018, data were collected through face-to-face interviews, clinical examinations, and laboratory tests. We defined six CVH metrics (three behavioral factors—smoking, body mass index, and physical activity; three biological factors—blood pressure, total cholesterol, and blood glucose) following the modified American Heart Association’s recommendations. We performed descriptive analysis separately for men and women. Results Of all participants, only 0.8% achieved ideal levels in all six CVH metrics. Men were more likely than women to have ideal levels in all CVH metrics but smoking. Women had higher prevalence of ideal global (9.7% vs. 7.8%) and behavioral (18.3% vs. 9.5%) CVH metrics (p < 0.001), whereas men had higher prevalence of ideal biological CVH metrics (5.4% vs. 3.5%, p < 0.001). The prevalence of ideal global and behavioral CVH metrics increased with age in both women and men (p for trend< 0.001). Women were more likely to be aware of their hypertension and diabetes, and to receive antihypertensive treatment, while men were more likely to achieve the goal of high cholesterol treatment (p < 0.05). Conclusions The CVH metrics among older adults living in the rural communities in China are characterized by an extremely low proportion of optimal global CVH metrics and distinct sex differences, alongside poor management of major biological risk factors.

Associations of the Glycaemic Control of Diabetes with Dementia and Physical Function in Rural-Dwelling Older Chinese Adults: A Population-Based Study

“…Data were collected through face-to-face interviews, clinical examinations, neuropsychological tests, and laboratory tests by trained medical staff. 17 , 18 Following a structured questionnaire, we collected data on sociodemographics (for example, age, sex, and education), lifestyle factors (for example, alcohol consumption and smoking), medical history (for example, hypertension, diabetes, coronary heart disease, and stroke), use of medications, cognitive function, and physical function. All medications were classified according to the Anatomical Therapeutic Chemical (ATC) system.…”

“…Participants in this cross-sectional population-based study were derived from the baseline assessments of the Multimodal Intervention to Delay Dementia and Disability in Rural China (MIND-China), 17,18 a participating project within the World-Wide FINGERS Network. 19 MIND-China targeted residents aged ≥60 years who were living in the rural communities of Yanlou Town, Yanggu County in western Shandong Province, China.…”

Red Cell Distribution Width and Dementia Among Rural-Dwelling Older Adults: The MIND-China Study

“…MIND-CHINA aims to test the effects of multidomain interventions on cognitive decline, onset of dementia, and disability among rural-dwelling elderly people. In March-September 2018, we performed the baseline assessments that targeted adults who were aged 60 years or older and living in the rural communities of Yanlou Town, Yanggu County in western Shandong province, China [ 19 ]. In this study, we excluded people who were aged 60–64 years because our study focused on late-onset dementia.…”

“…This population-based study involved the participants from the ongoing Multimodal Interventions to Delay Dementia and Disability in Rural China (MIND-China) [19][20][21], a participating project in the World-Wide FINGERS Network [22]. Brie y, all registered residents who were aged ≥ 60 years and living in 52 villages of Yanlou Town, Yanggu County, western Shandong Province, China, were eligible for the MIND-China study.…”
