Abstract
OBJECTIVE – To evaluate the association between body iron stores, dietary iron intake and the risk of diabetes in North China.
RESEARCH DESIGN AND METHODS – The data of a cross-sectional household survey in 2002 in Liaoning Province in North China was used. Final sample contained 2997 subjects aged 18 years old above in our study. Fasting plasma glucose and serum ferritin were measured. Dietary information was collected by three-day food records.
RESULTS – Serum ferritin was associated with elevated risk of diabetes even adjusted for age, gender, nondietary factors and dietary factors. No association among total iron intake, nonheme iron intake and diabetes risk was found. However, higher heme iron intake was significantly associated with elevated risk of diabetes after adjusting for known factors.
CONCLUSIONS – In Chinese the association among higher serum ferritin level, higher heme iron intake and elevated risk of diabetes were also found.
