Abstract
Diabet. Med. 27, 636–643 (2010) Abstract Aim To evaluate annual prevalence and incidence of Type 2 diabetes and to examine possible trends among adults in Taiwan. Methods A retrospective nationwide longitudinal study using the Taiwan National Health Insurance Research Database collected during 1999–2004. Adult patients aged ≥ 20 years old with prevalent and incident Type 2 diabetes were identified using ICD-9-CM diagnostic codes. Age-specific and age-direct-standardized annual incidence and prevalence were calculated to describe their trends in different gender and age group and compared using Poisson regression. Results During the study years, the age-standardized prevalence of Type 2 diabetes increased from 4.7 to 6.5% for men and from 5.3 to 6.6% for women. The increasing trends in prevalence were significant and higher among people aged < 40 and ≥ 80 years. The age-standardized incidence rates of Type 2 diabetes per 1000 person-years were approximately 7.6 and remain stable for men, but decreasing from 7.7 to 6.9 for women. However, the incidence increased significantly in younger adults aged < 40 years whose relative incidence (RI with 95% confidence interval) was 1.31 (1.20–1.42) for men and 1.04 (1.01–1.08) for women. The incidence trends for people aged ≥ 40 years were decreased for men and women. The differences in incidence trends between age groups and between genders were all statistically significant (all P < 0.001). Conclusions This study demonstrated a substantial increasing trend in Type 2 diabetes prevalence during 1999–2004 among adults in Taiwan. Despite the incidence decreased in older people, young men aged 20–40 years were most susceptible to higher incidence of Type 2 diabetes.Keywords
