Perceived stress and psychosomatic complaints in Swedish youth

Abstract

Abstract Background Psychosomatic complaints are common in youth, and are often assumed to reflect stress. Previous studies have reported associations between perceived stress and psychosomatic complaints. The current study extends this research by examining the longitudinal links between perceived stress and psychosomatic complaints. Methods The data was derived from two survey waves of the Swedish cohort study Futura01, with participants aged ∼17-18 in 2019 (t1) who were followed up in 2022 (t2; n = 2708). Perceived stress was measured by Cohen's Perceived Stress Scale (PSS-4). Psychosomatic complaints were captured by three items on the frequency of stomach ache, headache and sleeping problems, which were added to an index. Sex stratified linear regression analyses were performed, controlling for parental education and parental country of birth, based on information from official registers. The longitudinal analyses were carried out using the first difference (FD) approach, regressing the change in psychosomatic complaints on the change in perceived stress. Results Females reported higher levels of stress and of psychosomatic complaints than males at both time points. There were cross-sectional associations between perceived stress and psychosomatic complaints at t1 (females: b = 0.40, 95% CI 0.36, 0.45; males: b = 0.33, 95% CI 0.29, 0.38) and at t2 (females: b = 0.40, 95% CI 0.36, 0.45; males: b = 0.33, 95% CI 0.29, 0.38). The FD analyses showed that increases in perceived stress were associated with increases in psychosomatic complaints (females: b = 0.19, 95% CI 0.15, 0.23; males: b = 0.19, 95% CI 0.14, 0.23). Conclusions This study provides further empirical support for the assumption that psychosomatic complaints can be regarded as stress-related. Decreasing stress and strengthening young people's resources and strategies to cope with stress may thereby help to reduce the risk of developing psychosomatic complaints. Key messages • Psychosomatic complaints are responsive to perceived stress and can thus be regarded as stress-related. • Reducing stress and strengthening coping resources may increase well-being in youth.
