School-Related Stressors and the Intensity of Perceived Stress Experienced by Adolescents in Poland.

Higher stress reactivity during adolescence is a vulnerability marker of exposure to various environmental stressors. This study aimed to investigate the association between a high level of perceived stress experienced by adolescents and stressful stimuli induced from school environment, peer, and parental relationships. The data used were from a cross-sectional, observational study conducted in a stratified sample of 1846 adolescents (13-18 years) in the Wielkopolska province, Poland. Data were collected through self-administered questionnaires and anthropometric measurements. Perceived stress was assessed using the Perceived Stress Scale (PSS-10). The association of a high level of perceived stress with school-induced exposures was determined using multivariate logistic regression after adjusting for gender, age, height and weight status and interpersonal relationships (STATISTICA 13.1). It was found that girls were over three times more likely than boys to experience a high level of perceived stress. Moreover, girls appeared to be more vulnerable than boys to school-related stressors and weight status, while boys to stressors that can arise from interpersonal relationships. School environment was the only predictor factor of high perceived stress level with a large effect size in both boys (OR = 4.45; 95% CI: 3.11-6.36) and girls (OR = 6.22; 95% CI: 4.18-7.59). Given the findings of the present study, preventive programs are critical to mitigate the effect of stress from school on adolescents' health and well-being.
