[A cross-sectional study of impaired fasting glycaemia and diabetes mellitus in rural residents of Lanxi, Heilongjiang].

OBJECTIVE: To investigate the current status of impaired fasting glycaemia (IFG), diabetes mellitus (DM) and correlated factors, as well as on the awareness, treatment and control rate of diabetes mellitus in rural residents of Lanxi, Heilongjiang. METHODS: Cross-sectional and cluster sampling method was carried out on 3480 residents over 35 years of age, in rural residents of Lanxi Pingshan, Heilongjiang province. RESULTS: To male, female and all, the detecting rate of IFG were 5.06%, 4.38% and 4.68% respectively, and the standardization rate of IFG became 4.71%, 4.24% and 4.47% respectively. The prevalence rates of DM were 7.85%, 6.57% and 7.15% but after standardization, they became 7.22%, 6.62% and 6.80% respectively. Results did not show statistical difference between sex and the level of fasting glycaemia (chi2 = 2.725, P = 0.256). The prevalence rates of IFG and DM increased with age and difference was seen between age and fasting glycaemia level (chi2 = 58.115, P= 0.000). Data from multivariable stepwise analysis showed that age, smoking, BMI and high triglyceride were the significant factors in fasting glycaemia level, and the ORs (95% CI) were 1.518 (1.360-1.694), 1.277 (1.134-1.439), 1.187 (1.014-1.391) and 1.754 (1.385-2.220) respectively. The rates of awareness, treatment and control rate in DM were 12.74%, 9.43% and 4.72% respectively while the treatment rate among those who knew the disease was 74.07%. CONCLUSION: Our result showed that the isolating rate of IFG and the prevalence rate DM were high in this region, but the awareness, treatment and control rate in DM were low. It is essential to strengthen health promotion program on diabetic knowledge and to elevate the primary and secondary prevention in the rural of Heilongjiang, so as to raise the rate of control.
