A two-stage random probability sampling survey of the medical charts of family physicians in Newfoundland and Labrador was done; the first stage sampled physicians randomly, in proportion to the 5 health districts of the province; the second stage took a quota sample of the physicians' charts. The survey revealed a total population minimal prevalence rate of diagnosed diabetics of 3.55% (95% confidence limits 2.55, 4.55). This rate is higher than that found in the only other provincial survey done in Canada (the Prince Edward Island survey). Of diagnosed diabetics, 40% were found to be using insulin. This proportion is higher than other rates in North America. The prevalence rate was slightly higher in males (3.7%) than in females (3.4%).
对纽芬兰和拉布拉多省家庭医生的病历进行了两阶段随机概率抽样调查；第一阶段按照该省5个健康区的比例随机抽取医生；第二阶段对医生的病历进行配额抽样。调查显示，确诊糖尿病患者的总体最低患病率为3.55%（95%置信区间为2.55、4.55）。该患病率高于加拿大唯一的另一项省级调查（爱德华王子岛调查）中的患病率。在确诊的糖尿病患者中，发现40%正在使用胰岛素。这一比例高于北美的其他比例。男性患病率（3.7%）略高于女性（3.4%）。
