“…The implications of the high total prevalence of hyperglycemia are discussed. Diabetes 39:1131- 37,1990 S everal community studies have assessed the prevalence of diabetes with various methods for identifying and defining diabetes (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Studies in Massachusetts used postprandial blood glucose to confirm the status of previously known diabetic individuals and to identify diabetic individuals who were previously unknown (1,5,6).…”

The Wadena City Health Study was undertaken to assess the nature of type II (non-insulin-dependent) diabetes and its relationship to aging. This article reports the study methodology and prevalence estimates for type II diabetes and impaired glucose tolerance (IGT) for the adult population of Wadena, Minnesota. The sampling frame for the study included all known diabetic individuals and all other residents based on a complete citywide census of residents greater than or equal to 20yr of age. A stratified random sample that included three stratifying factors (age [20-39, 40-59, greater than or equal to 60 yr], sex, and self-reported weekly use of any prescribed medication was drawn from the other residents). The study protocol required diet preparation and two full mornings of testing. Data collected included height, weight, and blood pressure measurements and both a personal interview and a medications questionnaire. A 75-g oral glucose tolerance test (OGTT) and a test with a standard liquid meal (Ensure-Plus challenge test [EPCT], Ross) were done on two mornings, with the order of testing randomly assigned. Clinical tests included one-time samples for hemoglobin, glycosylated hemoglobin, plasma cholesterol, triglycerides, and lipoproteins. Blood samples for glucose and creatinine assays were taken during the OGTT; blood samples for glucose, free fatty acid, creatinine, and C-peptide were taken during the EPCT. Urine collections were performed for both challenge tests and assayed for C-peptide and creatinine. Seventy-one percent of the known diabetic subjects, and 65% of the stratified random sample participated in the study.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Redhead (1960), in Newcastle, found it to be 0.95%. Kenny et al (1951), in Canada, found it to be 1.2%, and with Wilkerson and Krall (1947) it was 1.4%. The newly discovered cases were also approximately in the numbers to be expected from other surveys.…”

In 1946 Wilkerson and Krall (1947) carried out the first community diabetes survey. They tested 70.60% of the population of 4,983 in Oxford, Massachusetts, and found 40 known cases of diabetes and 30 new cases. The total incidence was 1.4%,'. In Newmarket, Ontario, Kenny et al. (1951) tested 810% of the population over 6 years of age and found the incidence of diabetes to be 1.2%. They found 54 cases of diabetes, of which 21 were new cases. Since then mass screening surveys have been carried out in the United States and Canada, and in 109 surveys over Im. people have been tested. The incidence of diabetes in these surveys has varied between 1 and 1.5% (Joslin et al., 1959).In this country Redhead (1960) The aim of the present survey was to ascertain the prevalence of diabetes in Halstead, Essex, and to discover any unknown cases. An attempt was also made to classify tha cases of non-diabetic glycosuria. InvestigationThe survey was confined to the Urban District of Halstead. Halstead is a market and industrial town in north-west Essex and the 1951 census gave its population as exactly 6,000. The aim of th-survey was to test a specimen of urine of each of the resident population. The testing of blood samples was also considered, but the practical difficulties ruled this out.The survey extended over one year. The had been done it was well known that such a survey was in progress. Specimen bottles were delivered to each house in the town, together with a duplicated letter signed by all the doctors there. Four general practitioners work in the town in two partnerships, and the majority of people are patients of one or other of these partnerships. The explanatory letter described the aims of the survey, appealed for the co-operation of each person, and included a form which was to be completed and returned next day with the bottles. The form required the housholder to fill in the name, age, and occupation of each person in the house. Instructions were given to fill the bottles one hour after the main meal of the day. Details of any known diabetics in the house were obtained. In some cases these known diabetics submitted specimens for testing, but the majority did not. It was found that some people had recently had a specimen of urine tested. These included life insurance and antenatal examinations and investigations in hospital or by the general practitioner. It was decided that if the examinatioIn had been carried out within the past three months a further test was unnecessary. In doubtful cases a further sample was obtained. The bottles were collected on the following day together with the form. The electoral register was used as a basis for the survey this wvas carried out street by street, and it was occasionally found that the house did not appear on the register as it had been unoccupied when the register was compiled. In these cases the house was included in the survey.In the case of infants from whom it was impossible to obtain a specimen of urine the mothers were asked to press the end of a " clinistix ...

“…In the survey of Wilkerson and Krall (1947) and of Kenny, Chute, and Best (1951) postprandial blood sugars were taken as well as urine specimens, but the incidence of discovered abnormality was 0.6% and 0.5% respectively in the tested populations. It appears that a meal is considerably less provocative of hyperglycaemia than a 50-g. dose of glucose taken fasting.…”
