In this study the prevalence of diabetes in an adult community was determined using historical criteria and fasting hyperglycemia as definitions of known and previously unknown disease, respectively. Among the 4944 participants ages 30 to 95 years, the prevalence of known diabetes rose from less than 2% in persons less than 45 years of age to 6% in persons over 75 years of age. The prevalence of previously unknown diabetes, defined as a fasting plasma glucose greater than or equal to 140 mg/dl, was less than the prevalence of known diabetes, and relatively stable at 3-4% in persons over age 50. In this population, nearly twice as many men as women had diabetes. This sex ratio was associated with more excessive obesity in men.
在本研究中，采用既往标准和空腹血糖升高分别作为已知糖尿病和既往未知糖尿病的定义，来确定一个成人社区中糖尿病的患病率。在4944名年龄在30至95岁的参与者中，已知糖尿病的患病率从45岁以下人群中的不到2%上升至75岁以上人群中的6%。既往未知糖尿病的定义为空腹血糖大于或等于140mg/dl，其患病率低于已知糖尿病，在50岁以上人群中相对稳定在3%-4%。在该人群中，患糖尿病的男性人数几乎是女性的两倍。这种性别比与男性中更多的过度肥胖有关。
