Distribution And Related Factors Of Impaired Fasting Glucose And Diabetes In Middle And Old Aged Hypertensive Adults Of Lianyungang Rural Communities

Objective To investigate the distribution of impaired fasting glucose(IFG) and diabetesmellitus(DM) of middle and old aged hypertensive population in rural communities, andto explore their related factors，it provides a scientific basis for prevention and controlof the diabetes mellitus in this area. Methods Hypertensive population aged45~75years old in20towns which selected randomly by cluster sampling method from Ganyucounty and Donghai county of Lianyungang were recruited during October2008andJuly2009. Data were collected by questionnaire interview, physical examination andbiochemical test. Results A total of20217individuals were investigated and19093participants that without missing values of important variables were included in theanalysis,7008(36.7%) of men and12085(63.3%) of women. The mean age was59.56±7.57years old. The mean level of fasting blood glucose was5.82±1.90mmol/L.Prevalence of IFG was14.0%,14.7%in men and13.5%in women(χ2=2.02, P>0.05).Prevalence of diabetes mellitus was13.5%,12.3%in men and14.2%in women(χ2=12.57, P<0.01). The proportion of diabetes patients who knows their illness was27.9%, while22.8%in men and30.5%in women. After adjusting other risk factors, themultiple Logistic regression analysis shows that the risk of IFG was higher in men(OR:1.16,95%CI:1.02-1.33, P=0.02), and the risk of DM had not significant differences inmen and women. Age had a significant influence on the IFG and DM, when ageincreased10years old, the risk of IFG increased12%(OR:1.12,95%CI:1.02-1.22, P<0.01), and the risk of DM increased17%(OR:1.17,95%CI:1.05-1.28, P <0.01) inwomen, the influence in men was not significant. The risk of IFG and DM rising withthe growth of heart rates, systolic blood pressure, waist while decreasing with the growth of diastolic blood pressure. The risk of IFG who had family history of DM washigher(OR:1.24,95%CI:1.02-1.51, P=0.03), the risk of DM was higher too，89%higher in men (OR:1.89,95%CI:1.35-2.63, P<0.01) and77%higher in women (OR:1.77,95%CI:1.39-2.26, P<0.01). Conclusion The prevalence of impaired fastingglucose and diabetes mellitus was high in rural hypertensive population, and proportionof DM patients who knew their illness was low. Increased risk of IFG and DM may beinfluenced by various factors such as age, blood pressure, waist, family history ofdiabetes mellitus, current smoking, current drinking alcohol and heart rates.
