Vitamin mineral supplement usage by self-prescription is popular behavior among adolescents. This study was conducted to investigate the behaviors of vitamin·mineral supplement usage and the relationship between demographic variables and supplement usage by healthy adolescents. Nine hundred seventy two boys and girls, aged 13-18 years, attending general middle or high schools were chosen from various cities and rural communities in Korea. As a result, vitamin·]mineral supplements were taken by 31.3% of subjects. Users tended to take vitamin·mineral supplements more frequently when they were healthy than when they suffered from disease. The taking period of supplements was different according to school type such as middle or high school(p<.05), sex(p<.001) and residence of subjects(p<.01). The main information source of supplements was newspaper/magazine/TV, and it was affected by sex(p<.05) and residence(p<.01). Vitamin·mineral supplements were generally recommended by their mothers instead of health professionals. The commonly cited taking reason of supplements was affected by sex(p<.01)and socioeconomic status of family(p<.05). The frequently responded effect obtained from supplement use was recovery from fatigue and it was different according to sex(p<.01). The major mentioned reason of not taking vitamin·mineral supplements by non-users was 'I eat a balanced diet'. The most frequently consumed supplements were vitamin C, followed by multi-vitamins supplements, and this pattern was different according to school type(p<.001), sex(p<.01) and residence(p<.05). These findings show that the behaviors of vitamin·mineral supplement usage by subjects are not resonable, and their supplement usage tends to be affected by demographic variables. Therefore, nutritional understanding and education that are intended to form the resonable behaviors toward vitamin·mineral supplement usage of adolescents should be provided with considering the relationship between demographic variables and supplement usage.

Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

A positive correlation was found between Internet addiction and Internet expectation, depression and parent control over Internet use. A negative correlation was found between Internet addiction and interpersonal relationship, parent support and self-control. Multiple regression analysis revealed that the most powerful predictor of Internet addiction tendency was depression. Conclusion. Through the above results, it would be necessary to develop an Internet addiction prevention program for adolescents taking into account for the psychological factors such as depression and Internet use habits.

The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.
