Abstract P440: Ethnic and Gender-specific Prevalence of Type 2 Diabetes Mellitus among Adults in the California Health Interview Survey 2009
Background: The ethnic and gender-specific prevalence of type 2 diabetes mellitus (DM) have not been adequately documented in past studies; in addition, Asians and Hispanics have been often treated as aggregates, making it difficult to examine subgroup differences.
Methods: Using the California Health Interview Survey (CHIS) 2009 data, we identified the prevalence of DM and associated risk factors, stratified by gender, for the following ethnicities: Chinese, Filipino, South Asian, Japanese, Korean, Vietnamese, Cambodian, Mexican, Hispanic (Other), African American, and Caucasian (n=45,857, projected = 26.6 mil).
Results: Among men, the age-adjusted prevalence of DM was highest in Filipinos (15.8%), Japanese (11.8%), and Mexicans (10.2%). Among women, African Americans (13.3%) and Other Hispanic (10.7%) had the highest DM prevalence. Significant gender difference was observed in Caucasians and Mexicans, where men had a higher DM prevalence than women. In multiple logistic regression adjusting for age and other clinical and lifestyle risk factors, among women, compared to Caucasians, an increased likelihood of DM was seen in Koreans (OR=4.72, p<0.01), Cambodian (OR=3.84, p<0.05), and Other Hispanic (OR=2.90, p<0.01) Among men, compared to Caucasians, DM was more likely in Filipinos (OR=6.99, p<0.01), South Asians (OR=4.69, p<0.01), and Mexicans (OR=2.82, p<0.01).
Conclusion: Ethnic and gender differences in DM prevalence persist, even after adjusting for lifestyle and other risk factors. Racial/ethnic minority groups, particularly certain Asian subgroups, have the highest DM prevalence in California, despite risk factor adjustment. Different ethnic and gender- specific diabetes prevention approaches may be required.
