This study was carried out to investigate the distribution of body composition, and to analyze its relationship to dietary behaviors and life style. The study subjects were divided into 3 age groups; 30' years (n = 78) 40' years (n = 71) and 50' years (n = 44). The data was collected by physical measurement (Inbody 230) and questionnaires. The rate of disease and general characteristics were higher in the 50 year old group than in the other groups. Average amount of body water, protein, mineral and body fat were 29.0 kg (50.4%), 7.7 kg (13.4%), 2.8 kg (4.8%), 18.7 kg (31.5%), respectively. The rate of menopause was significantly different with increasing age. Menopause was 1.3%, 9.1%, 79.6% by age respectively. Body fat percent was significantly increased and body water decreased with age (p < 0.01). The fat composition was higher and the mineral content was lower in 50' year old group. Dietary behavior scores of 30' year old group was significant lower than in the other two groups (p < 0.001). The means of salty eating, skipping meals, fruit intake and food habits total point were significantly higher in the 50 year old group than in the other groups. There were significant positive correlations between age, BMI, waist hip ratio respectively (p < 0.01). There were significant negative correlations between age and body water, body mineral, skeletal muscle (p < 0.01, p < 0.05, p < 0.01). The results of this study suggested that nutritional management and education for adult women differ by age group.
