The subjects of our study were collected 246 students. The survey was conducted from April 25th to May 28th in 2012. The result indicated that cellphone overuse group has the lowerer self-control(t=3.53, p=.001) and the more mental health discomfort(t=-3.61, p=.000) than non-smart phone overuse group. In non-smart phone overuse group, the usage of smart phone was negatively correlated with self-control(r=-0.27, p=.005) and communication(r=-0.20, p=.043). And in the other group, the usage of smart phone was positively correlated with mental health discomfort(r=0.22, p=.009). These findings imply that it maybe needed to examine effect factors of the smart phone usage according to the level of smart phone usage.

Purpose: Koreans' internet and smartphone usage hours are steadily increasing and the dependence of young people on smartphones is causing social problems. Therefore, this study was conducted to examine health and dietary habits, as well as hair mineral contents according to the level of dependence of smartphone use among adolescents to clarify the interrelation of smartphone dependence, lifestyle, dietary behavior, and mineral nutrition status. Methods: A total of 80 smartphone-addicted adolescents participated in this study and were divided into three groups (general, potential and danger group) according to smartphone dependence. The subjects' lifestyles and dietary behaviors were then surveyed, and hair mineral contents were analyzed. Results: Higher smartphone dependence was associated with lower average weekly sleeping time and later first smoking age. In the danger group, the rate of eating fast and the rate of snacking twice a day was also relatively high. Parents (45.0%) and mobile (30.0%) were the factors having the greatest influence on an individual's dietary behavior. In the hair mineral analysis, all subjects had lower selenium concentrations and higher lead concentrations than normal. In addition, the levels of aluminum in the danger group were higher than in the normal range and the highest among the three groups. Conclusions: It is necessary to guide adolescents to use smartphones correctly and manage dietary habits. In addition, careful attention is needed the mineral nutritional status of smartphone-addicted adolescents.
