The purpose of this study was to examine the prevalence of individual risk factors for metabolic syndrome as well as the prevalence of metabolic syndrome in the National Health and Nutrition Examination Survey (NHANES) 2003-2006.
The analytic sample consisted of 3,423 adults, 20 years of age and over, from NHANES 2003-2006. The National Cholesterol Education Program's Adult Treatment Panel III (NCEP/ATP III) guidelines were used to identify adults who met their criteria for metabolic syndrome. Prevalence estimates were calculated for each risk factor for metabolic syndrome in addition to the prevalence of metabolic syndrome. Prevalence estimates and odds ratios were analyzed by sex and by age group, race and ethnicity, and body mass index (BMI) stratified by sex.
Approximately 34% of adults met the criteria for metabolic syndrome. Males and females 40-59 years of age were about three times as likely as those 20-39 years of age to meet the criteria for metabolic syndrome. Males 60 years of age and over were more than four times as likely and females 60 years of age and over were more than six times as likely as the youngest age group to meet the criteria. Non-Hispanic black males were about one-half as likely as non-Hispanic white males to meet the criteria for metabolic syndrome, while non-Hispanic black and Mexican-American females were about 1.5 times as likely as non-Hispanic white females to meet the criteria. Overweight males were about six times as likely and obese males were about 32 times as likely as normal weight males to meet the criteria. Overweight females were more than five times as likely and obese females were more than 17 times as likely as normal weight females to meet the criteria.
These results demonstrate that metabolic syndrome is prevalent and that it increases with age and with BMI. The prevalence varied by race and ethnicity but the pattern was different for males and females.
本研究旨在调查2003 - 2006年美国国家健康与营养检查调查（NHANES）中代谢综合征个体风险因素的患病率以及代谢综合征的患病率。
分析样本包括来自2003 - 2006年NHANES的3423名20岁及以上的成年人。采用美国国家胆固醇教育计划成人治疗专家组第三次报告（NCEP/ATP III）指南来确定符合代谢综合征标准的成年人。除了计算代谢综合征的患病率外，还计算了代谢综合征各风险因素的患病率估计值。患病率估计值和比值比按性别、年龄组、种族和族裔以及按性别分层的体重指数（BMI）进行分析。
约34%的成年人符合代谢综合征标准。40 - 59岁的男性和女性符合代谢综合征标准的可能性约为20 - 39岁人群的三倍。60岁及以上的男性符合标准的可能性是最年轻年龄组的四倍多，60岁及以上的女性则是六倍多。非西班牙裔黑人男性符合代谢综合征标准的可能性约为非西班牙裔白人男性的一半；而非西班牙裔黑人女性和墨西哥裔美国女性符合标准的可能性约为非西班牙裔白人女性的1.5倍。超重男性符合标准的可能性约为正常体重男性的六倍，肥胖男性则约为32倍。超重女性符合标准的可能性超过正常体重女性的五倍，肥胖女性则超过17倍。
这些结果表明代谢综合征很普遍，且随年龄和BMI增加。患病率因种族和族裔而异，但男性和女性的模式不同。
