在美国居住多年对青少年体重的影响尚不清楚。我们研究了波士顿青少年中第一代（即第1、1.5、2和3代）和体重指标之间的关系。数据来自马萨诸塞州波士顿市1,420名9 - 12年级公立学校学生的样本。我们使用自我报告的信息来计算年龄和体重特征（即身体质量指数（BMI）、BMI -score、超重状况），并进行多变量分析来估计年龄和体重特征之间的关联，调整种族/民族、性别、年龄和学校。在合并的多变量模型中，1.5代、第二代和第三代青年的平均BMI评分和平均BMI评分显著高于第一代青年。第二代青少年（RR 1.87, 95% CI 1.13-3.12）和第三代青少年（RR 2.06, 95% CI 1.21-3.50）也明显比第一代青少年更容易超重。在按性别分层的多变量模型中，这种模式仅在女性中存在。不同性别的人的BMI呈正线性趋势。这种联系背后的机制应该得到解决。
The effect of years of residence in the US on the weight of adolescents is unclear. We examined the association between generation (i.e. 1st, 1.5, 2nd, and 3rd) and weight indicators among Boston adolescents. Data are from a sample of 1,420 9–12th grade public school students in Boston, Massachusetts. We used self-reported information to calculate generation and weight characteristics (i.e., body mass index (BMI), BMIz-score, overweight status), and ran multivariate analyses to estimate the association between generation and weight characteristics, adjusting for race/ethnicity, gender, age and school. In pooled multivariate models, 1.5 generation, second generation, and third generation youth had significantly higher mean BMI scores and mean BMIz-scores than first generation youth. Second (RR 1.87, 95 % CI 1.13–3.12) and third generation youth (RR 2.06, 95 % CI 1.21–3.50) were also significantly more likely to be overweight than first generation youth. In multivariate models stratified by sex, this pattern persisted for females only. There is a positive, linear trend in BMI by generation that differs by gender. Mechanisms underlying this association should be addressed.
