背景虽然肥胖的患病率在美国成年人中显着增加，但健康风险因肥胖的严重程度而异。3级肥胖症患者（身体质量指数[BMI]大于或等于40）是最大的风险，但很少有关于这个亚组的信息。目的研究3级肥胖和长期趋势的相关性。设计，设置，成人和参与者（年龄大于或等于18岁）1990年（75600人）至2000年（164250人）期间参加行为风险因素监测系统电话调查的美国人。结果3级肥胖的患病率从1990年的0.78%上升到2000年的2.2%。2000年，黑人妇女（6.0%）、未完成高中学业的人（3.4%）和矮个子人中3级肥胖率最高。在11年的时间里，中位BMI水平增加了1.2个单位，第95百分位数增加了3.2个单位。因为这些极端的BMI水平与最严重的相关。健康并发症，各种疾病的发病率将大幅增加，在未来。
Context Although the prevalence of obesity has markedly increased among US adults, health risks vary according to the severity of obesity. Persons with class 3 obesity (body mass index [BMI] greater than or equal to 40) are at greatest risk, but there is little information about this subgroup.Objective To examine correlates of class 3 obesity and secular trends.Design, Setting, and Participants Adults (aged greater than or equal to 18 years) in the United States who participated in the Behavioral Risk Factor Surveillance System telephone survey between 1990 (75600 persons) and 2000 (164250 persons). Main Outcome Measure Body mass index calculated from self-reported weight and height.Results The prevalence of class 3 obesity increased from 0.78% (1990) to 2.2% (2000). In 2000, class 3 obesity was highest among black women (6.0%), persons who had not completed high school (3.4%), and persons who are short. During the 11-year period, the median BMI level increased by 1.2 units and the 95th percentile increased by 3.2 units.Conclusion The prevalence of class 3 obesity is increasing rapidly among adults. Because these extreme BMI levels are associated with the most severe. health complications, the incidence of various diseases will increase substantially in the future.
