Fasting blood glucose and risk of coronary heart disease, stroke, and all-cause mortality: a 17-year follow-up study of men born in 1913.

This report concerns the relationship between baseline levels of fasting blood glucose (FBG) in non-diabetics and the subsequent 17-year incidence of coronary heart disease (CHD), stroke and all-cause mortality. In 1963, 973 men aged 50 years were recruited from a general Swedish urban population for a prospective study of risk factors for CHD. Eight hundred and fifty-five (88%) men agreed to participate and have been observed for 17 years. The 832 men who had no history of myocardial infarction, stroke, diabetes mellitus or who had a fasting blood glucose below 7.0 mmol/l at baseline were selected for this analysis. CHD occurred in 106 men, 35 developed a stroke and 137 died during follow-up. When quintiles and deciles of the FBG distribution were considered, no trend of 17-year incidence of CHD, stroke or death was apparent. However, for men with an FBG above the 95th percentile (greater than 5.7 mmol/l) a non-significant trend towards increasing risk was indicated.
