We aimed to examine the association between immigrant generation and obesity among Californian adults and Asian Americans.
We pooled weighted data (n = 2,967) on Asian Americans from the 2013-2014 California Health Interview Survey. Overweight and obesity were defined using body mass indices (BMI) of 25 kg/m2 and 30 kg/m2, respectively, in non-Asians, compared with BMI of 23 kg/m2 (for being overweight) and 27.5 kg/m2 (for being obese) in Asians. First-generation or immigrant Asian Americans were defined as those born outside of the U.S. Second-generation Asian Americans were defined as those born in the U.S. with at least one foreign-born parent. All other Asian participants were classified as third-generation or higher. Multiple logistic regression analyses were used with adjustment for age, sex, family income, smoking status, marital status, education, physical activity, and fast food consumption.
Overall, 23.3% of the Asian population was obese, and 40.0% was overweight. The percentage of 1st, 2nd, and 3rd generation were 72.7%, 22.6%, and 4.6%, respectively. Overall, 1st generation of Asians had lower odds of being obese compared to Whites (OR = 0.34, 95%CI = 0.26-0.45). Multiple logistic regression analyses showed that overall, 2nd generation (OR = 1.69, 95%CI = 1.10-2.60) and 3rd generation (OR = 2.33, 95%CI = 1.29-4.22) Asians had higher odds of being obese compared to 1st generation Asians. Among Chinese, compared to the 1st generation, the 3rd generation had increased likelihood of being obese (OR = 6.29, 95%CI = 2.38-16.6).
Compared to Whites, Hispanics, and Blacks, Asian immigrants are less likely to be obese. Among Asians, 2nd and 3rd generations were more likely to be obese compared to 1st generation. The obesity rate seems to increase the longer Asian immigrants remain in the U.S.
我们旨在研究加利福尼亚州成年和亚裔美国人中移民代际与肥胖之间的关系。
我们汇集了 2013-2014 年加利福尼亚健康访谈调查中关于亚裔美国人的加权数据（n=2967）。非亚裔人群的超重和肥胖定义为体重指数（BMI）分别为 25kg/m2 和 30kg/m2，而亚裔人群的超重和肥胖定义为 BMI 为 23kg/m2（超重）和 27.5kg/m2（肥胖）。第一代或移民亚裔美国人定义为出生于美国以外的人。第二代亚裔美国人定义为在美国出生且至少有一位外国出生父母的人。所有其他亚裔参与者被归类为第三代或更高代。使用多变量逻辑回归分析进行调整，包括年龄、性别、家庭收入、吸烟状况、婚姻状况、教育程度、身体活动和快餐消费。
总体而言，亚裔人群中肥胖的比例为 23.3%，超重的比例为 40.0%。第一代、第二代和第三代的比例分别为 72.7%、22.6%和 4.6%。总体而言，第一代亚裔美国人肥胖的可能性低于白人（OR=0.34，95%CI=0.26-0.45）。多变量逻辑回归分析显示，总体而言，第二代（OR=1.69，95%CI=1.10-2.60）和第三代（OR=2.33，95%CI=1.29-4.22）亚裔美国人肥胖的可能性高于第一代亚裔美国人。在中国人群中，与第一代相比，第三代肥胖的可能性增加（OR=6.29，95%CI=2.38-16.6）。
与白人、西班牙裔和黑人相比，亚洲移民肥胖的可能性较低。在亚洲人群中，与第一代相比，第二代和第三代肥胖的可能性更高。随着亚洲移民在美国停留的时间延长，肥胖率似乎有所增加。
