Why the study?

This study aimed to examine the prevalence and correlates of metabolic syndrome in multi-ethnic populations of Northwest China using large-scale provincial health checking data.

Structured PICO

Population

9,745,640 Chinese adults aged ≥18 years in Xinjiang, China

Outcome

Prevalence of metabolic syndrome (MetS) defined by modified Adult Treatment Panel (ATP III) criteria

Metabolic syndrome is highly prevalent in Northwest China, particularly among Hui and Han ethnicities, older adults, and urban residents, highlighting the need for targeted prevention strategies.

Implication

Regional MetS prevalence data may guide local screening priorities; leaves open causal links and intervention effects pending longitudinal studies.

Abstract

PURPOSE: This study aimed to examine the prevalence and correlates of metabolic syndrome (MetS) in multi-ethnic populations of Northwest China based on Large-scale provincial health checking data. PATIENTS AND METHODS: A total of 9,745,640 Chinese aged ≥18 years in Xinjiang, the largest autonomous region of multi-ethnic in China, were enrolled from Feb. to Sep. 2019. MetS was defined by modified Adult Treatment Panel (ATP III) criteria. RESULTS: The overall prevalence of MetS was 20.85% [Sex: 20.06% female, 21.56% male; Age: 39.22% 60-years and above, 26.32% 40- to 59-years and 9.56% 18- to 39-years; Ethnicity: 28.19% Hui followed by Han (26.39%), Uyghur (18.56%), Other (18.61%), Kazak (17.98%), Mongolian (17.87%), Kyrgyz (14.44%)]. People living in cities and towns (23.03%) or North (24.78%) had higher prevalence of MetS than rural (19.94%) and South (17.66%). Although the prevalence of hypertension, smoking, drinking and lack of physical activity were higher in Kyrgyz, Mongolian and Kazak than those of other ethnic groups, the risk of MetS was lower. CONCLUSION: The results indicated that a high prevalence of MetS in Hui and Han groups and people living in cities and towns. Living in North Xinjiang and elder population tend to have higher prevalence of MetS. The prevention and management of MetS in these populations should be prioritized.
