Effects of Lifestyle on Lipid Indices

As the term suggests, the development of lifestyle-related diseases is greatly affected by the lifestyles of individuals. Primary prevention through a review of individuals\u27 lifestyles and promotion of healthy habits is an essential step to prevent these diseases. This study reports the results of a questionnaire survey and blood sampling conducted on 2,745 office workers aged 35, 40, 45, 50, and 55 years. Analysis of variance in the distribution of lipid indices [serum lipid values and body mass index (BMI) ] by age strata revealed statistically significant differences in total cholesterol (TC), triglyceride (TG), and BMI. The habit of regular exercise was markedly less frequent among the younger subjects. With respect to food preference, the older subjects tended to consume more fish and shellfish, soybean products, vegetables, and seaweed. Question items and lipid indices that showed significant differences in the analysis of variance were identified, and each was tested as a predictor variable in a logistic regression analysis. In this study, the consumption of noodles was associated with a higher BMI among males, but not among females. Higher TC levels were associated with a higher age and the consumption of eggs among males, and a higher age among females. No factors were found to affect the HDL cholesterol levels. Higher TG levels were associated with the consumption of bread and noodles among males, and with a smoking habit among females. These results warranted further examination of the factors affecting lipid indices
