Behavior and Lifestyle Factors Related to Quality of Life in Junior High School Students

Objectives: To analyze actual conditions of the quality of life (QOL) in junior high school students, we developed a questionnaire based on the PRECEDE-PROCEED model, and we conducted a survey by using this questionnaire. Methods: We conducted a workshop organized with 29 specialists on school health and community health to develop the questionnaire. The QOL outcome was assessed by the QOL Profile-Adolescent Version (QOLPAV). The subjects of the questionnaire surveys were 1600 general students in four junior high schools. To investigate a correlation between QOLPAV, behaviors and three enhancing factors, two different multiple regression models were constructed. Results: The question battery for QOLPAV was found to be a high value of Chronbach’s α. Among present subjects, 16.5% were categorized as “problematic” or “very problematic” classified by QOLPAV scores. In the first multiple regression model, significantly high odds ratios were obtained between the QOLPAV and 4 questions for behaviors, such as “studying with high motivation” (OR 1.64), “getting along well with my friends” (2.72), “having things I am interested in” (1.70), and “making my own decisions” (1.80). In the second model, significantly high odds ratios were obtained commonly between the above 4 questions about behaviors and 2 questions on enabling factors, such as “easy to understand lessons” (1.32-1.71) and “speaking to friends easily” (1.30-3.22). Conclusions: 1) We developed a questionnaire to analyze the actual condition of QOL in junior high school students with sufficient validity and availability. 2) Among the present subjects, 16.5% were found to be problematic QOLPAV. 3) Among the factors of behaviors, those representing positive willing and high coping ability with the elements of each school life contributed significantly to the QOLPAV. And among enhancing factors, “enabling factors” and “reinforcing factors” were stronger contributors to the behaviors strongly related to the QOLPAV than that of “predisposing factors”.
