This study examined the relationship between basic psychological need fulfillment (BPNF) and school happiness in relation to the intensity of physical activity exhibited by adolescents during physical education (PE) classes and their obesity levels. We measured BPNF and school happiness using a questionnaire administered to 600 junior high school students. After exclusion, 532 questionnaires were analyzed. A 3D accelerometer (GT3X model) from Actigraph and the body mass index were used to measure physical activity intensity and obesity, respectively. The findings of this study indicate that BPNF and school happiness were significantly associated with physical activity intensity. Specifically, students who engaged in high-intensity physical activity exhibited higher levels of BPNF and school happiness. Additionally, BPNF and school happiness were not significantly related to obesity, whereas a significant relationship was observed between BPNF, school happiness, and the interaction between physical activity intensity and obesity level. This finding implies that adolescents with higher physical activity intensity and lower obesity reported higher levels of BPNF and school happiness. These findings suggest that physical activity intensity during PE classes significantly influences emotional development. Therefore, incorporating moderate-to-vigorous physical activity into PE may serve as a strategy for promoting emotional development in adolescents.

Excessive focus on appearance or lookism requires social attention as it can have negative consequences on individuals’ psychological and mental states related to health and sustainable social practice. As part of a healthy and sustainable social practice, this study tests the mechanism of enhancing appearance-related health campaign’s effectiveness through the O1-S-O2-R framework. Participants were 220 Korean college students with being 141 male and 78 female and they completed an on-line survey. The result of SEM analyses confirmed the O1-S-O2-R model. As the result of hypotheses testing, health campaign contents suggesting anti-lookism and diverse beauty standards have attracted the attention of people whose parents conversed using relatively less healthy-appearance talk when growing up and who had higher self-objectification scores with body surveillance and body shame. Interpersonal conversations and thoughts on the media content played a mediating role in the model, while health campaigns had a higher persuasive effect on campaign evaluation and the behavior intention of spreading the campaign’s content. Implications of the findings were discussed regarding health campaign designers and individuals, including parents, in education settings.

This study aimed to compare physical activity patterns according to the type of physical education by sex and body mass index categories among Korean adolescents. We analyzed physical activity using an accelerator in a physical education class among Korean middle school students (1305 boys and 1328 girls). An independent t-test and regression analysis were conducted to compare differences between the obesity groups by sex. As game play time increased, light activity increased in boys in the normal group. Among the girls, sedentary time decreased in the normal, at-risk for obesity, and obese groups. Moderate activity increased in the underweight, normal, at-risk for obesity, and obese groups. Vigorous activity increased in the normal group. As free activity time increased, sedentary time also increased in the normal, at-risk for obesity, and obese groups. Vigorous activity decreased in the normal group. Among the girls, sedentary time increased in the underweight group. Light activity decreased in the underweight and normal groups. A strategy to increase physical activity during physical education class is to increase game play time for girls and decrease free activity time for boys.
