Abstract
In order to prevent ischemic heart disease in working adult males, we analyzed risk factors by age groups based on data from an eight-year follow-up study of male employees enrolled in the Denso Health Insurance Program. Of the 27,945 male employees aged 30 to 55 enrolled in the program in 2003, the data of 19,742 (70.6%) who underwent regular health checkups were analyzed. Information obtained from health insurance claims for hospitalization and cause of death from discontinuation data were used to analyze risk factors for ischemic heart disease by age group. Hazard ratios and 95% confidence intervals were estimated from Cox proportional-hazards models. In males aged 30-39 years, a BMI of 25.0-27.5 was associated with a 2.21 higher risk of ischemic heart disease (95%CI: 1.01-4.84) than those not overweight (BMI of <25.0); LDL of 160 mg/dl or more was associated with a 3.85 higher risk (95%CI:1.62-9.14) than LDL of less than 120 mg/dl; and FPG of 160 mg/dl or more was associated with a 6.43 higher risk (95%CI: 1.02-40.63) than a FPG of less than 110 mg/dl. For males aged 40-55 years, higher LDL was a risk factor of ischemic heart disease (1.95 (95%CI: 1.28-2.98) and 1.97 (95%CI: 1.34-2.90) for LDL of more than 160 mg/dl and 140...Continue Reading
