自20世纪80年代以来，肥胖的患病率大幅上升。虽然移民是美国人口中增长最快的部分，但人们对这一群体的肥胖问题知之甚少，也不知道他们在饮食和运动方面的临床咨询。目的估计移民亚群中肥胖的患病率，量化其与美国居住时间的关联程度，并根据出生地、种族和民族描述报告的饮食和运动咨询。采用2000年全国健康访谈调查数据的设计、设置和参与者横断面研究。体重指数（BMI，以体重（公斤）除以身高（米）的平方来衡量）基于自我报告的身高和体重测量，以及自我报告的饮食和运动咨询率。结果32374名受访者中，14%为移民。移民的肥胖率为16%，美国人的肥胖率为22%。在美国居住不到1年的移民中，年龄和性别调整后的肥胖率为8%，但在美国居住至少15年的移民中，这一比例为19%。在调整饲料、社会人口和生活方式因素后，在美国生活10至15年和至少15年与BMI分别增加0.88和1.39相关。除外国出生的黑人外，这种关联在15年或更长时间内对所有移民亚群都很显著。此外，移民比美国出生的人更不可能报告与临床医生讨论饮食和运动(18%比24%，P
Context The prevalence of obesity has increased substantially since the 1980s. While immigrants are the fastest growing segment of the US population, little is known about obesity or clinician counseling about diet and exercise in this group.Objectives To estimate the prevalence of obesity among immigrant subgroups and quantify the magnitude of the association with duration of US residence, and to describe reported diet and exercise counseling by birthplace, race, and ethnicity.Design, Setting, and Participants Cross-sectional study using data from the 2000 National Health Interview Survey.Main Outcome Measures Body mass index (BMI, measured as weight in kilograms divided by the square of height in meters) based on self-reported height and weight measurements, and self-reported rates of diet and exercise counseling.Results Of 32374 respondents, 14% were immigrants. The prevalence of obesity was 16% among immigrants and 22% among US-born individuals. The age- and sex-adjusted prevalence of obesity was 8% among immigrants living in the United States for less than 1 year, but 19% among those living in the United States for at least 15 years. After adjusting forage, sociodemographic, and lifestyle factors, living in the United States for 10 to 15 and at least 15 years was associated with BMI increases of 0.88 and 1.39, respectively. The association for 15 years or more was significant for all immigrant subgroups except foreign-born blacks. Additionally, immigrants were less likely than US-born individuals to report discussing diet and exercise with clinicians (18% vs 24%, P
