Hyperinsulinemia is characterized by jointly disturbed plasma VLDL, LDL, and HDL levels. A population-based study.

Plasma very low density lipoprotein (VLDL) cholesterol and triglyceride, low density lipoprotein (LDL) cholesterol and triglyceridea, high density lipoprotein (HDL) cholesterol, glucose and insulin response (sums of 1- and 2-hour postload oral glucose levels), body mass index (BMI), and blood pressure were determined in a representative sample (n = 542) of the adult Israeli Jewish population. Persons with diabetes or on antihypertensive medications were excluded. Total VLDL and LDL fractions were estimated from their cholesterol and triglyceride subfraction levels that were standardized relative to the mean of the reference group (participants free of glucose intolerance, obesity, and hypertension--the GOH conditions). Hyperinsulinemia and disturbed levels of VLDL and LDL were defined as levels equal to or greater than the 75th percentile and those of HDL, equal to or less than the 25th percentile of their respective reference group distributions. When VLDL was disturbed jointly with LDL and HDL, the mean insulin response adjusted for age, gender, glucose response, BMI, blood pressure, and smoking was high compared to the reference group (166.0 vs. 122.5, p less than 0.001). With isolated disturbed VLDL, or disturbed LDL and HDL but normal VLDL, the mean insulin response resembled the reference group. The adjusted risk ratio for this jointly disturbed lipoprotein profile among hyperinsulinemic individuals was 3.4 (95% confidence limits 2.6 to 4.4, p less than 0.001) with no further association with the GOH conditions. We conclude that hyperinsulinemia is characterized by an atherogenic lipoprotein profile.

Senile cataract and glucose intolerance: the Israel Study of glucose Intolerance Obesity and Hypertension (The Israel GOH Study).

Association of "senile" cataract (SC) with glucose intolerance (impaired tolerance and diabetes) was assessed by sex and age in a random population sample comprising 930 individuals aged 40-70 yr, who underwent concurrent oral glucose tolerance test and ophthalmoscopy. The eye examination was performed without knowledge of the glucose tolerance status. SC was defined as lens opacification preventing visualization of the eyeground or as surgical aphakia due to SC. To assess the independent effect of hyperglycemia, glycosylated hemoglobin (HbA1) was determined in 769 participants. In men, no association was found between SC, glucose intolerance, and HbA1. In women of all ages, glucose intolerance was associated with an SC risk ratio of 6.1 (95% confidence limits 3.3-11.1; P less than 0.001). Furthermore, SC was associated in women with increased HbA1 independently of the effect of glucose intolerance (P less than 0.01). These findings confirm the reported association of SC with diabetes (although unlike the Framingham and HANES population studies, the association was confined in women), indicate its presence at all degrees of glucose intolerance, and suggest a possible independent role of nonenzymatic glycosylation in its pathogenesis.
