The purpose of this study was to examine the relationship between the perceived physical health status of Korean adolescents, adults, and elderly adults and their frequency, intensity, time, and duration of exercise. In 2012, 1,144 adolescents (under 18 years old), 6,474 adults (19-64 years old), and 1,382 elderly adults (over 65 years old) participated in the Korean Survey on Citizens’ Sports Participation Project (N = 9,000). The association between selfreported health status and exercise was assessed using multivariate logistic regression analyses, controlling for sex and age. The study found that the health status of adolescents showed little or no association with the frequency, intensity, time, or duration of exercise. However, the health status of adults and elderly Koreans was associated with the frequency, intensity, time, and duration of exercise. The physical condition and health status of adolescents was better than that of adults and the elderly, many of whom had declining health. Our findings show the need for exercisepromotion programs customized for particular age groups. The limitations and strengths of the study are discussed, as well as the implications for future research and managerial applications for promoting exercise in each age group.

This study investigates whether daily Internet use time is related to the school performance of Korean adolescents. We therefore analyzed raw data from the 2009 Korea Youth Risk Behavior Web-based Survey-V (KYRBWS-V), in which 75,066 students from the middle-school first grade to the high-school third grade participated. We assessed the association between daily Internet use time and school performance by using multivariate logistic regression analysis adjusted for age, body mass index, education level of parents, and economic status of the family. For boys, the odds ratio (OR) [95% confidence interval (CI)] for recording ≥ average school performance and daily time spent on Internet use was 1.876 (1.752–2.008, p < 0.001) for ≤1 hour, 1.564 (1.467–1.667, p < 0.001) for >1–≤2 hours, 1.158 (1.079–1.242, p < 0.001) for >2–≤3 hours, and 0.759 (0.695–0.828, p < 0.001) for over 4 hours, when compared to those who never used the Internet. For girls, the OR (95% CI) for recording ≥ average school performance and daily Internet use time was 1.729 (1.607–1.860, p < 0.001) for ≤1 hour, 1.503 (1.399–1.616, p < 0.001) for >1–≤2 hours, 1.193 (1.100–1.293, p < 0.001) for >2–≤3 hours, and 0.809 (0.725–0.903, p < 0.001) for over 4 hours, when compared to those who never used the Internet. It was concluded that Korean adolescents who spend ≤3 hours per day on the Internet are predisposed to an increase in performance levels at school, whereas those who spend over 4 hours per day on the Internet are predisposed to a decrease in school performance levels.

The purpose of this study was to investigate the relationship between weight status and recreational drug use in Korean adolescents. A total of 72,399 adolescent students (38,152 boys and 34,247 girls) from the middle first to high third grade participated in the 5th Korea Youth Risk Behaviour Web-based Survey (KYRBWS-V) project in 2009. They were assessed for body mass index (BMI) and recreational drug abuse. The associations between BMI and recreational drug use were examined using multivariable logistic regression analysis after adjusting for the covariate variables of age, smoking frequency and cigarette consumption, frequency of alcohol consumption and severe alcohol intoxication, amount of alcohol consumed, parents’ education level, economic status, sedentary activities during the week, mental stress, sleep duration, frequency of vigorous and moderate physical activities, and muscular strength exercises during the week. For boys, the odds ratio (OR) (95% confidence interval [CI]) between overweight and drug use were 0.990 (0.723–1.356; p = 0.950) for almost none, 0.939 (0.521–1.693; p = 0.834) for past use, and 0.791 (0.385–1.624; p = 0.523) for present use. The OR (95% CI) between obesity and drug use was 0.731(0.508–1.052; p = 0.091) for almost none, 0.755 (0.389–1.465; p = 0.407) for past use, and 0.701 (0.314–1.565; p = 0.386) for present use. For girls, the OR (95% CI) between overweight and drug use was 1.112 (0.702–1.763; p = 0.650) for almost none, 1.103 (0.464–2.619; p = 0.825) for past use, and 0.927 (0.267–3.218; p = 0.905) for present use. The OR (95% CI) between obesity and drug abuse was 0.594 (0.261–1.352; p = 0.215) for almost none, 1.318 (0.462–3.764; p = 606) for past use, and <0.001(<0.001–<0.001; p = 0.998) for present use. We concluded that recreational drug use had no correlation with overweight and obesity in Korean adolescents.
