目的了解宁波市某区45~64岁人群空腹血糖和糖耐量分布特征,为中年人群的糖尿病防治提供依据。方法通过横断面调查方法,分层整群随机抽取宁波市某区45~64岁中年人群,进行空腹血糖和糖耐量试验,分析流行病学特征。采用χ2检验、趋势χ2检验、方差分析、调整率等进行统计描述及检验。结果共调查45~64岁人群6 170人,空腹血糖平均值为5.29mmol/L,男性高于女性(F=9.35,P=0.002)。糖耐量2h血糖平均值为6.41mmol/L,女性高于男性(F=18.67,P=0.000)。联合筛查结果为糖尿病检出率5.25%,糖尿病前期检出率17.59%。仅检测空腹血糖,中年人群糖尿病的漏检率为45.37%(147/324),糖尿病前期的漏检率为75.85%(823/1 085)。结论糖尿病对中年人群的影响不容忽视,加做糖耐量试验对减少糖尿病和糖尿病前期者的漏诊意义重大。
Objective To understand the distribution of fasting blood glucose and glucose tolerance in 45-64-year-olds in a district of Ningbo City, and to provide evidences for the prevention and treatment of diabetes in middle-aged population. Methods By cross-sectional survey, stratified cluster randomly selected middle-aged population of 45-64 years old in a district of Ningbo City for fasting blood glucose and glucose tolerance test, and analyzed the epidemiological characteristics. Using χ2 test, trend χ2 test, analysis of variance, adjustment rate and other statistical description and test. Results A total of 6 170 people aged 45-64 years were investigated. The average fasting blood glucose was 5.29 mmol / L, higher in males than in females (F = 9.35, P = 0.002). Glucose tolerance 2h average blood glucose 6.41mmol / L, women than men (F = 18.67, P = 0.000). Joint screening results for the detection rate of 5.25% diabetes, pre-diabetes detection rate of 17.59%. Only the detection of fasting blood glucose, middle-aged population diabetes detection rate was 45.37% (147/324), pre-diabetes missed detection rate of 75.85% (823/1 085). Conclusion The impact of diabetes on middle-aged population can not be ignored. Adding glucose tolerance test is of great significance to reduce the missed diagnosis of diabetes and pre-diabetes.
