Objectives. To investigate whether the association between nativity, length of residence and BMI varied across diverse Asian ethnic groups in California. Methods: Using pooled data from the California Health Interview Survey for the years 2001, 2003 and 2005, the authors examined whether the relationship between nativity, US length of residence and BMI varied across six Asian ethnic groups (Filipinos, Koreans, Chinese, South Asians, Japanese and Vietnamese). Results. In crude analyses, there was evidence of a strong differential association between nativity, length of residence and BMI across Asian ethnic groups (p<.0001). After controlling for age, gender, and marital status, the association between nativity, length of residence and BMI continued to vary across subgroups; regardless of ethnicity, all US-born groups had higher BMI than their foreign-born counterparts, although the differences were not always statistically significant. The differences in BMI according to length of residence varied across ethnic groups both in terms of strength of the association and statistical significance. Conclusions. The association between nativity, US length of residence and BMI varies across Asian ethnic subgroups. Although, additional research is needed, the diversity in BMI patterns found in this study should be closely considered in future obesity prevention, treatment, and research efforts.
