The responses to a questionnaire survey on the patterns of eating activity of 1, 160 female university students were used to conduct of cluster analysis on 8 parameters, including the frequency of buying from convenience stores, eating out, and purchasing prepared meals and box lunches. The relationships among the eating activity patterns obtained, daily living habits and health condition were then analyzed. The eating activity patterns were classified into four clusters : cluster 1, mainly utilizing convenience stores; cluster 2, eating in; cluster 3, eating out; and cluster 4, mainly utilizing stores other than convenience ones. The ratios of cluster 2 on daily living habits such as the regular life pattern and on health habits such as eating breakfast nearly every day were significantly higher than the ratios of cluster 3; contrarily, the ratios of cluster 3 with regard to self-assessed subjective symptoms such as loss of vitality and increased drowsiness were higher than those in cluster 2. Significant differences were also observed in the health habit scores (clusters 2 >4 >1 >3) and in the score for subjective symptoms (clusters 2< 4< 1< 3). The relationship between daily living habits and health condition showed cluster 2 to be the best, followed by cluster 4, cluster 1, and cluster 3 as the worst.
