This survey aimed to clarify the mechanism of the effects of smartphone use on psychological and physical conditions among elementary and junior high school students. A total of 709 elementary school students and 3,405 junior high school students who live in the Chugoku District of Japan participated in this study. The result showed that the amount of time using smartphones was correlated positively with later bedtimes, frequency of physical symptoms (e.g."I get tired easily") and negative feelings about school life (e.g. "I don't want to go to school"). Covariance structural analyses indicated that the amount of time using smartphones led to later bedtimes, and later bedtimes increased negative self-evaluation of psychological and physical conditions such as "I can't get motivated", "I get tired easily" and "I feel like acting violently". In order to improve children's psychological and physical conditions, it is important to improve their bedtimes.
