Metabolic syndrome (MS) is recognized worldwide as an important public health concern. However, little information is available for rural populations in Brazil. The aim was to determine the prevalence and risk factors associated with MS in a rural village in Brazil in 2004.
Cross-sectional population-based study, in Virgem das Graças, a rural community in the Jequitinhonha Valley, State of Minas Gerais.
MS was the dependent variable, defined as any three of these risk factors: arterial hypertension, high glucose or triglyceride concentrations, low high-density lipoprotein cholesterol and abdominal obesity. MS prevalence, according to selected socioeconomic and demographic variables (age, skin color, marital status, schooling and smoking habits), was determined in 251 subjects aged 20-88 years. Multivariate logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals.
MS prevalence was 21.6% (7.7% for men and 33.6% for women); the age-adjusted prevalence was 19.0%. The highest prevalences were observed for women > 60 years of age (52.9%) and women with body mass index (BMI) >or= 25 kg/m(2) (64%). Age, sex and BMI were associated risk factors for MS, while skin color was only significantly associated with MS for women. The models were adjusted for age, smoking habits, marital status, skin color and schooling.
BMI and age were independently associated factors for MS in this rural community. These findings provide important evidence on the prevalence of MS as a public health problem, particularly for women and overweight individuals.
代谢综合征（MS）在全球范围内被视为一个重要的公共卫生问题。然而，关于巴西农村人口的相关信息却很少。本研究旨在确定2004年巴西一个乡村中MS的患病率及其相关危险因素。
基于人群的横断面研究，研究地点为米纳斯吉拉斯州热基蒂尼奥尼亚河谷的一个农村社区——维尔任达斯格拉西亚斯。
将MS作为因变量，其定义为具备以下任何三个危险因素：动脉高血压、高血糖或高甘油三酯浓度、低高密度脂蛋白胆固醇以及腹型肥胖。在251名年龄在20 - 88岁的受试者中，根据选定的社会经济和人口统计学变量（年龄、肤色、婚姻状况、受教育程度和吸烟习惯）确定MS患病率。采用多因素逻辑回归来估计比值比（OR）和95%置信区间。
MS患病率为21.6%（男性为7.7%，女性为33.6%）；年龄调整后的患病率为19.0%。60岁以上女性的患病率最高（52.9%），体重指数（BMI）≥25 kg/m²的女性患病率最高（64%）。年龄、性别和BMI是MS的相关危险因素，而肤色仅在女性中与MS显著相关。模型对年龄、吸烟习惯、婚姻状况、肤色和受教育程度进行了校正。
在这个农村社区中，BMI和年龄是MS的独立相关因素。这些发现为MS作为一个公共卫生问题的患病率提供了重要证据，尤其是对于女性和超重个体。
