Objective: To investigate the secular trend of prevalence and risk factors for type 2 diabetes mellitus (T2DM) in the rural Chinese population.
Methods: 16,953 participants aged 35 to 74 years old participated in a cross-sectional study in a Henan rural area in 2007-2008. The InterAsia study which is a nationally representative sample of rural Chinese residents was done in 2000 -2001. The rural Chinese adult participants in InterAsia study were compared with the 2007-2008 data to analyze the secular trend of prevalence and risk factors of T2DM.
Results: In 2007-2008, the aged-adjusted prevalence of T2DM was 7.72% (male 7.71%, female 7.73%). The aged-adjusted prevalence of T2DM elevated from 5.27% to 7.72% during seven years. The prevalence of T2DM was progressively increased with age from 2000-2001, but the prevalence of T2DM for the participants aged from 55 to 64 was highest after seven years in 2007-2008. Compared two studies,the exposed rates of hypertension, abdominal obesity, dyslipidemia were increased from 26.82%, 26.39%, 20.45% to 29.82%, 46.1%, 44.20%.
Conclusion: The prevalence of T2DM and it's risk factors increase rapidly in the rural Chinese population, and the intervention program are urgently needed.
