[Effects of life style on serum cholesterol levels and atherogenic index]

Life style as related to levels of serum total, HDL and LDL cholesterol, and atherogenic index (AI) were studied in the context of prevention of atherosclerosis and cardiovascular diseases, and maintenance of an active long life. Mean values of serum cholesterol, AI and elements of life style were compared on the basis of responses to a questionnaire and results of a medical examination for 369 men and women aged over 30 years in a district of Akita prefecture. Life style appeared to have a tendency of influence in men and AI appeared to be elevated with a life style of limited physical activity that was comparatively light and with no drinking. Many men reporting a life style of light activity were unemployed and tended to attempt to make up for the activity by an exercise program. As for women, there appeared to be no influence of life style on the aging phenomena. Many of the women who were unemployed tended to be single, to have limited and light daily activity, a regular exercise program, and reported getting adequate sleep. Personal awareness of body fat and health conditions seemed to be reflected in levels of cholesterol and AI, and therefore raising a person's awareness level is important for adopting personal health management habits.
