The objective of this study was to reveal the differences in lifestyle and physical condition between subjects who live and with family. The subjects were 1,238 young women, aged from 18 to 22 years old, who were recruited in Hiroshima Jogakuin University. The percentage of living alone was 22% in the subjects. Compared with parents' home life group, living alone group had high percentage of breakfast skippers (36% compared with 19%: <0.001) and lower consumption of vegetables (47% of 0～1 serving/day compared with 30%; <0.001). However, there were no significant differences in body composition and physical condition in each group. Additionally, about 30% in each group ate dinner and/or snack after 21 o'clock, almost of them went to bed after 24 o'clock, and about 30% of them did not exercise everyday. Although lifestyle of living alone group was more irregular than that of parents' home life group. it was thought that their lfestyles were controlled not by capability of health care management but by thier family who live together. Therefore, when we promote healthy lifestyle in young women, it is necessary to consideration which they live alone or not, and to take appropriate advices, such as how to cook and manage their lifestyle.
