[Purpose]The purpose of this study was to examine the multiple relationships between body proportion, physical fitness, and daily life time of young children, using three years of longitudinal data.[Method]The study subjects comprised 148 young children from whom longitudinal data were collected for three years. We collected data on body proportions, physical fitness, and daily life time.[Results and Discussion]The results confirmed that the change in physical fitness score was the highest in the obesity trend group, followed by the maintaining body proportion group, and that this change was the least in the slim trend group. Regarding the daily life time, significant difference was observed in the change of the obesity index by the time spent on TV and video systems. Further, the time spent by the children playing on a PC and video games was marginally significant. It was also confirmed that the time spent on TV and video systems was shorter among children in the slim trend group. Our findings suggest that the improvement of daily life time, desirable change in body proportions, and improvement in physical fitness might be affected by multiple activities related to the mutual factor.
