^aNumbers in cells are adjusted odds ratios with calculated 95% confidence intervals, two-tailed probabilities. Values are weighted to the 2000 census age distribution of Koreans in California.

^bVariables are coded as yes (1) and no (0).

^cContinuous score on the acculturation scale. Higher scores correspond to higher assimilation to US lifestyle and lower scores correspond to adhering to more traditional Korean culture.

^dPre-menopausal model X² = 22.5, df = 6, p<.001; Nagelkerke R² = .307

^eMenopausal model X² = 23.0, df = 6, p<.001; Nagelkerke R² = .201
