A cross-sectional survey of a one in five random sample of apparently healthy adults aged 40 years and older was done in 17 family practice clinics in Newfoundland, in order to pick up previously undiagnosed diabetics, by fasting blood sugar (FBS) measurements. From a sample of 2,087 people, 1,767 were tested. Forty-eight persons had an elevated FBS on the first test, but only 19 had a sustained high FBS when a second test was done. There were 16 previously-known diabetics for each new diabetic found; in this population it was not worth screening healthy persons for diabetes. Testing should be restricted to high-risk people only. As a result of this study, the diabetes prevalence in the 40+ population rose from 12.4% to 13.1%.
为了通过空腹血糖（FBS）测量来发现之前未被诊断出的糖尿病患者，在纽芬兰的17家家庭诊所对40岁及以上明显健康的成年人进行了五分之一的随机抽样横断面调查。在2087人的样本中，1767人接受了检测。48人首次检测时空腹血糖升高，但第二次检测时只有19人持续高血糖。每发现1例新糖尿病患者，就有16例之前已知的糖尿病患者；在这个人群中，对健康人进行糖尿病筛查是不值得的。检测应仅限于高危人群。这项研究的结果是，40岁及以上人群的糖尿病患病率从12.4%上升到了13.1%。
