Metabolic syndrome (MetS) is a cluster of major risk factors for cardiovascular diseases. We aimed to estimate prevalence and distribution of MetS among middle-aged and elderly adults in China.
The present analysis used data from a national study in 2014-2015. We defined MetS by different definitions, and compared results of the present study and previous nationally representative studies to illustrate possible temporal changes in MetS prevalence.
The estimated prevalence of MetS was 18.4% by the ATP III criteria, 34.0% by the revised ATP III criteria, and 26.9% by IDF criteria. The prevalence was higher in women, older adults, those with lower education level, and in economically developed regions. Contrasting with previous national studies, adults in urban areas had a lower rate of MetS than those in rural areas (odds ratio 0.94; 95% CI 0.92-0.97). Rural adults had worse deterioration or less improvement in abdominal obesity, overweight, hypertension, and high fasting plasma glucose, than urban adults, which was particularly striking for women.
While measures to prevent and control cardiovascular diseases need to be strengthened in China, rapid increasing risk factors among rural residents and women should be prioritized in making public health policy decisions. KEY MESSAGES Our study assessed prevalence and temporal changes of MetS among Chinese population with the most recently completed and the largest sample size. The current prevalence of MetS was higher in women, older adults, those with lower education level, and in economically developed regions and the CVD risk factors among rural residents and women should be prioritised in making public health policy decisions. A comparison of results of the present study and previous national studies showed that rural adults had worse deterioration or less improvement in abdominal obesity, overweight, hypertension, and high fasting plasma glucose, than urban adults, which was particularly striking for women.
代谢综合征（MetS）是心血管疾病主要危险因素的聚集。本研究旨在评估中国中老年人 MetS 的患病率和分布情况。
本分析使用了 2014-2015 年全国性研究的数据。我们根据不同的定义来定义 MetS，并比较本研究与之前具有全国代表性的研究结果，以说明 MetS 患病率的可能的时间变化。
根据 ATP III 标准，MetS 的估计患病率为 18.4%，根据修订后的 ATP III 标准为 34.0%，根据 IDF 标准为 26.9%。女性、老年人、受教育程度较低者和经济发达地区的患病率较高。与之前的全国性研究相比，城市地区成年人的 MetS 患病率低于农村地区（比值比 0.94；95%可信区间 0.92-0.97）。农村成年人在腹部肥胖、超重、高血压和高空腹血糖方面的恶化或改善程度不如城市成年人，这在女性中尤为明显。
虽然中国需要加强预防和控制心血管疾病的措施，但在制定公共卫生政策决策时，应优先考虑农村居民和女性快速增加的危险因素。
本研究评估了中国人群中最新和最大样本量的 MetS 患病率和时间变化。目前，女性、老年人、受教育程度较低者和经济发达地区的 MetS 患病率较高，农村居民和女性的心血管疾病危险因素应优先考虑制定公共卫生政策决策。本研究结果与之前的全国性研究结果进行比较，结果显示，农村成年人在腹部肥胖、超重、高血压和高空腹血糖方面的恶化或改善程度不如城市成年人，这在女性中尤为明显。
