This study investigated the correlation between smartphone addiction and eating behaviors of 288 elementary school students (fifth and sixth grades) in the Ansan area. Addiction and normal groups consisted of 29 (10.1%) and 259 students (89.9%). Average usage time of the smartphone addiction group was higher than that of the normal group (P<0.001). Percentages of using a smartphone when eating meals as well as skipping meals due to using a smartphone were also higher in the addiction group than the normal group (P<0.01). Degree of reduction of physical activity and sleep disorders due to using a smartphone were higher in the addiction group than the normal group (P<0.001). However, nutritional knowledge related to protein and dietary life scored lower in the addiction group than the normal group (P<0.05). Correlation between smartphone usage time and eating behaviors was as follows: smartphone usage time on weekdays increased with elevated usage time on weekends in the addiction group (+0.742) (P<0.001) and the normal group (+0.762) (P<0.001). Frequency of snack intake in the addiction group increased with elevated usage time on weekdays (+0.460) (P<0.05). Sleeping time of the normal group decreased with elevated usage time on weekdays (-0.150) (P<0.05), and good eating behaviors decreased with elevated usage time the on weekend (-0.143) (P<0.05). Consequently, smartphone addiction in elementary school students showed negative eating behaviors.

The purpose of this study is to clarify the factors that affects smartphone addiction of elementary school students. The subjects were 263 students, from 4 elementary schools located in G-city. Data were collected from July, 2014 and analyzed using SPSS 19.0 program. The prevalence of addiction risk group and non-addicted group were 16.0% and 84.0%, respectively. The variables which had statistically significant differences with smart phone addiction of general characteristics are grade, living together family, economic status, school record, motivation for usage, advantage of usage and using time (p<.05). There was pure correlation between the smartphone addiction and impulsivity (r=.496, p<.001), daily stress (r=.471, p<.001). However, perceived parental attitude (r=-.375, p<.001) and self-esteem (r=-.444, p<.001) were inverse correlation with smartphone addiction. Higher using time, higher impulsivity and higher daily stress were all associated with increased of smartphone addiction level. These results suggest that more attentions should be given to early adolescents and could be effectively used as fundamental data to develop intervention programs, which can prevent the smartphone addiction.

Despite the ever-increasing smartphone addiction of adolescents and a variety of consequent problems not much research has been conducted on the issue. It is time to prepare a set of countermeasures to protect them from the addiction. The central purpose of the current paper is to identify how use motives, self-control and social withdrawal affect their smartphone addiction. It was found (i) that the motives of information acquisition, social relationship, amusement and use of leisure time exert significant influence on smartphone addiction, (ii) that less self-control and greater impulsiveness result in greater addiction, and (iii) that social withdrawal of users also have significant effect on smartphone addiction. Such findings are expected to provide base data for any attempt to develop countermeasures against addiction. It is desirable that we had better check the play activities of adolescents and develop self-control programs to help them alleviate impulsiveness than simply impose strict restrictions on the use of smartphones.
