Relation between Lifestyle Factors and High-Density Lipoprotein Cholesterol Subfraction Levels among Healthy Adults Living in a Rural District / 日本農村医学会雑誌

ABSTRACT

Serum levels of total high-density lipoprotein cholesterol (HDL-C) and its subfractions (HDL<SUB>2</SUB>-Cand HD<SUB>L3</SUB>-C) were measured in 227 healthy Japanese adults. These values were related to a number of lifestyle factors.<BR>On co-variance analysis, alcohol drinking had an independent contribution to HDL-C and HDL<SUB>3</SUB>-C (p<0.05) in males. Cigarette smoking showed no association with subfractions of HDL-C in males. Three physical activities-sport, work and leisure time activity-had no significant association with subfractions of HDL-C. The degree of obesity as expressed by body mass index (BMI) was significantly negatively related (p<0.05) to HDL-C and HDL<SUB>2</SUB>-C levels among females. Among males, although a trend test showed no statistically significant relation to BMI, HDL-C and HDL<SUB>2</SUB>-C levels were significantly higher (p<0.05) in the normal group (20≤BMI<25) than in the obese group (BMI≥25).
