OBJECTIVE Plasma total adiponectin is a marker of insulin resistance, but its role in predicting cardiovascular events is unclear. We aimed to investigate the role of adiponectin as a predictor of cardiovascular risk in middle-aged men, and to describe the association between adiponectin and glucose metabolism. METHODS In this population-based prospective study of middle-aged men (n=3885), total adiponectin was analyzed. All individuals had undergone an oral glucose tolerance test (OGTTs), and the mean follow-up duration was 27 years. Regression analyses were carried out for indices of glucose metabolism in relation to quintiles (Q1-Q5) of total adiponectin levels. After stratification for smoking or not, the association between total adiponectin and the first incidence of fatal or non-fatal cardiovascular disease (CVD) was analyzed, using Cox's proportional-hazards regression model. RESULTS In a separate multiple-regression analysis and after adjusting for possible confounders, the relationship between adiponectin levels and markers of glucose metabolism were found to be significant (P<0.05). However, adiponectin did not independently predict the risk of stroke, coronary events, or a combination of these two outcomes. CONCLUSIONS Levels of total plasma adiponectin are not useful for predicting long-term cardiovascular events in middle-aged men, but are strongly associated with glucose metabolism and markers of insulin resistance.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
