This study was conducted to assess validity (sensitivity and specificity) of a diabetes screening program in Hamedan, Iran district health centers. Eight hundred and thirty-five persons older than age 30 in Hamedan rural areas who had no diabetes risk factors were tested for fasting glucose, then the results of the national diabetes program in the area were added to these results. Finally, sensitivity, specificity, and positive and negative predictive values (PPV and NPV, respectively) of type 2 diabetes were calculated. Nineteen persons (2.28%) had impaired fasting glucose (110-126 mg/dl), and three (0.36%) had diabetes (fasting glucose ≥ 126 mg/dl) according to standard diagnostic criteria. Prevalence and incidence rates of diabetes were 2.97% and 7.53 per 1,000. Sensitivity, specificity, PPV, and NPV of the diabetes screening test were 80.23%, 61.67%, 2.2%, and 99.65%, respectively. The study revealed that the primary screening program in district health centers had an acceptable sensitivity (80.23%) and a low specificity (61.67%).
本研究旨在评估伊朗哈马丹地区卫生中心糖尿病筛查计划的有效性（敏感性和特异性）。对哈马丹农村地区 835 名年龄大于 30 岁且无糖尿病风险因素的人群进行空腹血糖检测，然后将该地区国家糖尿病计划的结果添加到这些结果中。最后，计算了 2 型糖尿病的敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）。根据标准诊断标准，有 19 人（2.28%）存在空腹血糖受损（110-126mg/dl），有 3 人（0.36%）患有糖尿病（空腹血糖≥126mg/dl）。糖尿病的患病率和发病率分别为每 1000 人 2.97%和 7.53%。糖尿病筛查试验的敏感性、特异性、PPV 和 NPV 分别为 80.23%、61.67%、2.2%和 99.65%。研究表明，地区卫生中心的初级筛查计划具有可接受的敏感性（80.23%）和较低的特异性（61.67%）。
