We evaluated whether duration of time in the US is associated with obesity risk in NYC Chinese immigrants. We analyzed cross-sectional survey data on 2072 men and women. Duration of US residence was categorized into ≤5, 6–15, and 15 years and over. Obesity was defined using WHO Asian standards: BMI of 27.5 kg/m 2 or greater. Diet and physical activity (PA) were assessed as potential explanatory variables. After adjusting for covariates, increased time in the US was associated with an increased obesity risk (OR 1.49; 95 % CI 1.06, 2.08 for 15 years or more vs. ≤5 years); and in separate analysis, with having reported no work related PA (OR 0.76; 95 % CI 0.59, 0.99). Findings suggest that increased time living in the US is associated with an increased obesity risk, a finding possibly explained by a shift to more sedentary lifestyle characteristic of the transition of immigrants to the US.
