The prevalence of diabetes in a rural population of Jamaican adults.

Abstract：

:The prevalence of diabetes, the interrelationship of blood glucose, serum insulin, and lipids, and their relationship to ischemic heart dise ase in a rural Jamaican community were investigated. The people were mo stly of West African descent. Occupations were primarily agricultural w ith much physical labor. Approximately 80% of total claories in their d iet were from carbohydrates. Of 696 25-64 year old persons, a response rate of 77.3% was achieved. The patients, after an overnight fast, drank a 7-oz bottle of Glucola which was the equivalent of a 100 gm glucose load. Electrocardiograms (EKGs), blood pressure readings, a chest X-ray, and skinfold tests for obesity were done. A family history was obtained. Blood and urine specimens were taken before the glucose was given. 1 hour after the glucose was given, blood and urine specimens were also taken. Those with blood glucose of 180 mg% or more were given a 3-hour glucose tolerance test. Of the 525 persons who had the 1-hour test, 23 were found to be glycosuric. Of these, 11 were not shown to be diabetic by the 3-hour glucose test. Of the 502 with negative urines, 34 were positive on blood tests. The rates increased with age, except in the oldest age groups (p less than .05 for males and p less than .001 for females). There was no relationship between the number of live births and the 1-hour blood glucose tests. There was neither increase in the diagnosis of diabetes nor increase in variance with number of children. The known diabetics were fatter and had higher triglycerides than others. Cholesterol was higher in all male diabetics but not in females. Only 2 persons experiencing effort pain had EKG changes. Data from this study indicate that no statistically significant association exists between levels of glycemia and blood pressure or prevalence of cardiovascular disease. The physical fitness acquired from walking and working in a hilly area may be a factor.
