ABSTRACT
<p><b>OBJECTIVE</b>To examine the prevalence changes of diabetes mellitus (DM) and impaired fasting glucose (IFG) from 2003 to 2010 in the health check-up subjects in Shanghai.</p><p><b>METHODS</b>Health check-up subjects were divided into ten groups by sex and each 5 years old, and the prevalence of crude DM, crude IFG were calculated first. According to Chinese sex and age structure of China Population Statistics Yearbook 2006, sex and age standardized DM and standardized IFG were computed.</p><p><b>RESULTS</b>In the same year, the prevalences of crude DM and IFG increased with increasing age for both male and female, reached the summit at 60 - 69 age group, when at ≥ 70 age group, they had a down trend and were still at higher level. The prevalences of crude DM were 3.99% (986/24 699) in male and 1.61% (176/10 948) in female in 2003, and were 7.85% (3366/42 899) and 2.55% (531/20 820) in 2010. The prevalences of crude IFG were 9.97% (2462/24 699) in male and 5.88% (644/10 948) in female in 2003, and were 30.96% (13 283/42 899) and 17.16% (3573/20 820) in 2010. The prevalences of age standardized DM in 2003 and 2010 were 3.89% and 6.90% for male (χ(2) = 371.89, P < 0.01), 2.12% and 3.23% for female (χ(2) = 29.32, P < 0.01), respectively. The prevalences of age standardized IFG in 2003 and 2010 were 9.51% and 28.55% (χ(2) = 3865.56, P < 0.01) for male, 6.97% and 17.88% (χ(2) = 790.81, P < 0.01) for female. The prevalences of age and sex standardized DM were 3.00% and 5.05% (χ(2) = 385.39, P < 0.01), and prevalences of age and sex standardized IFG were 8.23% and 23.17% (χ(2) = 4480.21, P < 0.01).</p><p><b>CONCLUSION</b>From 2003 to 2010, prevalences of DM and IFG had increased greatly. It concluded that first-level prevention of DM for health check-up subjects should start from youth, and should lay emphasis on population of IFG, especially for male.</p>
