Information on the distribution of Metabolic syndrome (MetS) and its combinations by urban/rural areas in lower-middle income countries has been limited. It is not clear how the various combinations of MetS components varied by urban/rural population and if particular combinations of MetS are more common. This study aimed to estimate the prevalence of MetS and combinations of MetS components according to sex and urban/rural areas from a nationally representative sample of Thai adults.
Data from the fourth National Health Examination Survey of 19,256 Thai adults aged 20 years and over were analyzed. MetS was defined using the harmonized criteria of six international expert groups with Asian-specific cut-point for waist circumference.
The prevalence of MetS was 23.2% among adults aged ≥ 20 years (19.5% in men and 26.8% in women). Among men, the prevalence of MetS in urban was higher than those in rural areas (23.1% vs 17.9%, P < 0.05), but among women, the prevalence was higher in rural areas (27.9% vs 24.5%, P < 0.05). Overall, an individual component of low high density lipoprotein (HDL) and hypertriglyceridemia were more common in rural areas, while obesity, high blood pressure and hyperglycemia were more common in urban areas. The most common combination of MetS components in men was the clustering of low HDL, hypertriglyceridemia, and high blood pressure (urban: 3.4% vs. rural: 3.9%, adjusted OR 0.9, 95%CI 0.7, 1.1). Among women, the most common combination was the clustering of obesity, low HDL, and hypertriglyceridemia (urban: 3.9% vs rural: 5.9%, adjusted OR 0.8, 95%CI 0.6, 0.9), followed by the clustering of these three components with high blood pressure (urban: 3.1% vs. rural 4.5%, adjusted OR 0.8, 95%CI 0.7, 0.9).
Metabolic syndrome affects both urban and rural population with different pattern of MetS combinations. Dyslipidemia and obesity were the most common components among women in rural areas, hence, interventions to prevent and control these factors should be strengthened.
中低收入国家有关代谢综合征（MetS）及其组合在城乡地区分布的信息有限。目前尚不清楚 MetS 成分的各种组合在城乡人群中的变化情况，也不清楚是否存在更常见的 MetS 组合。本研究旨在根据泰国成年人的全国代表性样本，按性别和城乡地区估计 MetS 及 MetS 成分组合的患病率。
对年龄在 20 岁及以上的 19256 名泰国成年人的第四次国家健康检查调查数据进行了分析。使用六个国际专家组的协调标准并结合亚洲特定的腰围切点定义 MetS。
≥20 岁成年人中 MetS 的患病率为 23.2%（男性为 19.5%，女性为 26.8%）。男性中，城市地区的 MetS 患病率高于农村地区（23.1%比 17.9%，P<0.05），而女性中，农村地区的患病率较高（27.9%比 24.5%，P<0.05）。总体而言，在农村地区，低高密度脂蛋白（HDL）和高三酰甘油血症的单个成分更为常见，而肥胖、高血压和高血糖在城市地区更为常见。男性中最常见的 MetS 成分组合是低 HDL、高三酰甘油血症和高血压的聚集（城市：3.4%比农村：3.9%，调整后的 OR 0.9，95%CI 0.7，1.1）。在女性中，最常见的组合是肥胖、低 HDL 和高三酰甘油血症的聚集（城市：3.9%比农村：5.9%，调整后的 OR 0.8，95%CI 0.6，0.9），其次是这些三个成分与高血压的聚集（城市：3.1%比农村：4.5%，调整后的 OR 0.8，95%CI 0.7，0.9）。
代谢综合征影响城乡人群，其 MetS 组合模式不同。血脂异常和肥胖是农村地区女性最常见的成分，因此，应加强预防和控制这些因素的干预措施。
