Abstract

In the present study, we examined the lifestyles of Japanese women whose body shapes had changed in different ways over approximately 20 years. The purpose of this study was to clarify the relationship between body shape change and lifestyle by evaluating daily living based on amount of activity. Using a body shape vector, we classified 24 women in their 40s and 50s into 3 groups with different body shape changes. An experiment was conducted on weekdays for 1 week with 24 healthy women in their 40s and 50s with different body shape changes. The amount of activity of the non-dominant wrist and trunk, subjective evaluation of sleep quality, and subjective state of activity were surveyed for 1 week. For the analysis, the amount of activity was classified on a time series for weekdays during active periods, sleeping periods, and non-measurement periods (e. g., bathing) using a subjective activity state. We then evaluated subjects' activity, sleep, and variation in the pace of life. Women who had maintained the same body shape throughout life were found to have little sedentary time, high trunk movement during active periods, little activity during sleep periods, high subjective sleep scores, and a varied pace of life. In order to identify important lifestyle factors, it is necessary to evaluate the amount of activity throughout the day, including during sleep. In conclusion, the present results suggest that, compared with women who had not maintained the same body shape over 20 years, women who had maintained the same body shape had a consistently sensible diet, had little sedentary time and sustained a high level of trunk movement during the day, slept well at night, and had a varied pace of sleep-wake rhythm.
