[Relations between weight changes and various biological parameters. Results of a longitudinal epidemiological...

Weight changes over a three year period were measured on a group of about 1400 working men aged 46 to 52 years and related to several biological parameters (cholesterolemia, triglyceridemia, uricemia, glycemia and blood pressure). We observed: a) a slight increase in mean weight over the three year period; b) significant correlations between weight change and changes in these biological parameters. These results are compared to those found in cross sectional studies. Their implications for public health and prevention of ischemic heart disease are discussed.
