Insights
Cardiovascular disease risk factor clustering is high in older Xinjiang residents, affecting over half the population. Strategies targeting sex, age, region, and ethnicity are needed for prevention and management.
Area of Science:
- Gerontology
- Epidemiology
- Public Health
Background:
- Cardiovascular disease (CVD) risk factor (CRF) clustering significantly elevates CVD prevalence and mortality.
- Limited data exists on CRF clustering in community-dwelling older adults in Xinjiang, China.
Purpose of the Study:
- To investigate the prevalence and patterns of cardiovascular disease risk factor clustering among older adults in Xinjiang.
Main Methods:
- A cross-sectional study involving 86,298 participants aged 60 and above from six regions in Xinjiang.
- Multilevel random sampling was employed, with data analyzed from participants with complete information.
Main Results:
- High prevalence of individual CRFs: smoking (9.4%), hypertension (52.1%), diabetes (16.8%), dyslipidemia (28.6%), and overweight/obesity (62.7%).
- 55.9% of participants exhibited clustering of CRFs, with 85.7% having at least one CRF.
- CRF clustering was more prevalent in men, the 60-69 age group, northern Xinjiang, and the Kazakh ethnic population, even after adjusting for age and sex.
Conclusions:
- The prevalence of CRFs and their clustering is substantial in Xinjiang's older population.
- Significant variations in CRF clustering exist across sex, age, region, and ethnicity.
- Targeted prevention and management strategies for CVD risk reduction are essential for this demographic, considering specific subgroup characteristics.
Objective:
The clustering of multiple cardiovascular disease (CVD) risk factors (CRFs) increases the risk of CVD prevalence and mortality. Little is known about CRF clustering among community-dwelling older people in Xinjiang. The objective of this study was to explore the prevalence of CRF clustering in this population.
Design:
Cross-sectional study.
Setting:
Xinjiang, China.
Participants:
Multilevel random sampling was used to survey individuals aged ≥60 in six regions of Xinjiang. In total, 87 000 participants volunteered, with a response rate of 96.67%; 702 participants with incomplete data were excluded and data from 86 298 participants were analysed.
Outcome Measures:
The prevalence of smoking, hypertension, diabetes, dyslipidaemia and overweight/obesity was 9.4%, 52.1%, 16.8%, 28.6% and 62.7%, respectively. The prevalence of CRF clusters among people of different ages, regions and ethnic groups differed significantly. The 85.7% of the participants presented at least one CRFs and 55.9% of the participants presented clustering of CRFs. The proportion of CRF clusters tended to be higher in men, 60-69-year-old group, northern Xinjiang and the Kazakh population. After adjusting for age and sex, logistic regression analysis revealed that men, 60-69-year-old group, northern Xinjiang and the Kazakh population were more likely to have clustering of CRFs, compared with their counterparts.
Conclusions:
The prevalence of CRFs in the older Xinjiang population is high and their clustering differs by sex, age, region and ethnicity. CRF prevention and management should be active in this population, and strategies to reduce CVD risk based on sex, age, ethnic group and region are warranted.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
