The Effect of Stress on the Physical Health of High School Students between Grades 10-12 in Thailand

Currently, teenagers are under high social pressure. This affects stress levels and can have a negative effect on physical health. Therefore, we should study this matter to find a way to reduce stress levels in high school students, especially those in grades 10 through 12. The objectives of this survey research are 1) to study the stress and physical health levels of high school students; 2) to compare the stress levels of high school students in Thailand, focusing on students in grades 10-12, and 3) to study the relationship between stress level and physical health among high school students. The sample group used in the study were students in grades 4-6 in Thai and international schools, with a total of 222 participants. Data were collected using questionnaires and analyzed by valid percentages, standard deviation, mean, one-way ANOVA test (F-test), independent sample (t-test), and Pearson’s correlation. The results of this research found that high school students report high levels of stress on average and moderate levels of physical health problems. When comparing the stress levels and physical health problems of students classified by educational level and type of school, it was found that there was no difference in education level or type of school. Still, the assumption that physical health problems are related to stress levels is highly possible. Stress and physical health problems are significantly related at 0.01. Further, this study could be improved in comparison to the effect of stress on physical health in different grades and at every age. This study would help raise awareness among adolescents who are maturing.
