Smartphones use for a long period of time can cause health problems including physical condition, psychological condition and sleeping status. In addition, smartphones use may affect menstruation related symptoms. This study was conducted using a self-administered questionnaire between June and November in 2016 to clarify the differences in physical and psychological condition, sleeping status and menstruation-related symptoms before and after starting to use smartphones in female university students in Japan. We recruited 273 female nursing students and the response rate was 95.2%. We found significant changes after starting to use smartphones regarding eyestrain (p < 0.001), posture (p = 0.002), stiffness of neck, back and shoulders (p < 0.001), level of outdoor activity (p < 0.001), difficulty concentrating (p < 0.001), lack of motivation (p < 0.001), and sensitivity to stress (p = 0.005). Moreover, we also found that fatigue before menstruation and headache/low back pain during menstruation were higher after starting to use smartphones. The proportions of students with irritability and depressive feeling as emotional premenstrual symptoms appeared higher after starting to use smartphones. These results imply that young women should refrain from using smartphones if they have visual display terminal-related symptoms, disturbance of sleep pattern and menstruation-related symptoms before and during menstruation.
