Plasma cholesterol, triglycerides, glycohemoglobin, and other covariates were measured in 212 type I (insulin-dependent) diabetic subjects on entry into a longitudinal study of diabetes and again after an average interval of 3.7 yr. Changes in individual cholesterol and triglyceride values over time were significantly correlated with changes in glycohemoglobin. After adjustment for potentially confounding covariates, plasma cholesterol declined by 2.2% (0.1 mM) for each percentage-point reduction in glycohemoglobin and plasma triglycerides declined by 8% (0.8 mM) per percentage point glycohemoglobin. Increased insulin dose was independently associated with increased plasma triglycerides, after adjusting for glycohemoglobin level and other covariates. However, insulin dose was not related to plasma cholesterol. Improved diabetic metabolic control, measured as declining glycohemoglobin, is the variable most closely associated with reduced plasma lipids in a population of typical type I diabetic patients.
