Objective: Diabetes risk changed as immigrant populations adopt new lifestyles. Therefore we started the Filipino Women’s Dietary and Health Study. We first compared the prevalence of fasting hyperglycemia among Filipino women and Korean women. Methods: Participants included volunteer, community-dwelling women, aged ≥ 20 years, and were recruited at churches, and multicultural family support center. Participants were fasting more than 12 hour. And we taken the blood sampling and participants undergo interviews. We also selected age matched Korean women from 2009 KNHANES dataset. Results: Filipino women were more obese than Korean women [body mass index (23.5 ± 4.2 vs. 22.7 ± 3.7, P = 0.034), waist circumference (80.3 ± 12.3 vs. 76.3 ± 9.8, P < 0.001)]. However, Filipino women showed lower fasting blood glucose level (85.7 ± 11.1 vs. 91.1 ± 15.4, P < 0.001). And there were no different in insulin resistance (Homa-IR; 2.30 ± 2.77 vs. 2.17 ± 1.30, P = 0.444). The prevalence of impaired glucose tolerance (FBS > 100 mg/dL) was more higher in Korean women (11.8% vs. 6.1%, P = 0.033). Conclusion: Korean women is more slender but prone to IGT than Filipino women.
