Key result
The prevalence of metabolic syndrome in Chinese adults nearly doubled from 2002 to 2017 (P for trend <0.001), with the largest increase occurring in younger men and driven primarily by rising rates of high blood pressure.
Why the study?
Metabolic syndrome has been increasing worldwide, but the secular change in its components remains unclear.
Cross-Sectional (n=38,725)
Yes
p-value: p=<0.001
The prevalence of metabolic syndrome has doubled among Chinese adults in Shanghai between 2002 and 2017, driven largely by increases in blood pressure, blood glucose, and waist circumference.
Alerts clinicians to rising metabolic syndrome in younger Chinese men; leaves open optimal prevention targets.
AIMS/INTRODUCTION: Metabolic syndrome (MS) has been increasing worldwide. The secular change in MS components, however, remains unclear. This study aimed to examine the dynamic change in metabolic health status in Chinese adults. MATERIALS AND METHODS: Three population-based surveys using multistage stratified sampling were performed in Chinese aged 35-74 years in Shanghai in 2002-2003 (n = 12,302), 2009 (n = 7,400), and 2017 (n = 19,023). MS was defined according to the Adult Treatment Panel III criteria for Asian-Americans. Generalized Estimating Equations and Cochran-Armitage Trend Test was used to assess the prevalence trend over the years. RESULTS: The prevalence of MS doubled in Chinese adults over the period (P for trend < 0.001). The largest increase occurred in younger men. Among MS components, the prevalence of high waist-circumference (HWC), high blood glucose (HBG) and high blood pressure (HBP) increased in all subjects, whereas the prevalence of high triglycerides (HTG) and low high-density lipoprotein cholesterol (LHC) increased in men but decreased in women. The increase in HBP contributed most to elevated MS, followed by HBG and HWC, resulting in the HBP-HBG-HWC the most common cluster of MS components. Metabolically unhealthy overweight also grew over the period. CONCLUSIONS: Metabolic health status has been exacerbating in Chinese adults and may increase burden of non-communicable diseases.

Yang et al. (2021) conducted a cross-sectional in Metabolic syndrome (n=38,725). Time period (2002-2017) vs. 2002-2003 baseline was evaluated on Prevalence trend of metabolic syndrome (p=<0.001). The prevalence of metabolic syndrome in Chinese adults nearly doubled from 2002 to 2017 (P for trend <0.001), with the largest increase occurring in younger men and driven primarily by rising rates of high blood pressure.
