Abstract
In order to investigate the obesity prevalence and its impact on lifestyle related diseases among the working population, we have investigated the chronological data of annual health check up of an occupational setting in Japan. We have compared the prevalence of hypertension, hyperlipidemia, and hyperglycemia in 1999 between the workers in 1995 who become obese in 1999 and who did not, both of whom were categorized as "healthy" in 1995, based on the data of 9,196 "healthy" male workers between 40 to 59 years old. For hypertension statistically positive correlations were observed for the two age groups; 40 to 49, and 50 to 59. For hyperlipidemia statistically positive correlations were observed for the three age groups; 30 to 39, 40 to 49, and 50 to 59. Finally, in the case of hyperglycemia, the two age groups; 40 to 49, and 50 to 59, showed positive correlations. This result has strongly suggested that it is very important to organize an effective anti-obesity program for middle aged men in order to reduce the disease burden of diabetes and other lifestyle related diseases.
