Are psychosocial factors associated with low-back pain among nursing personnel?

The aim of this study was to investigate whether psychosocial factors at work are related to low-back pain among nursing personnel. It was conducted as a short-term follow-up study of 200 Danish female nursing personnel, providing care for the elderly. Self-reported measures of psychosocial factors such as time pressure, emotional demands of clients, control and social support were obtained by questionnaire at baseline, while stress, physical exertion and low-back pain were reported by diary records made in two, three-day periods in the subsequent 6 months. The study examines the possible influence of psychosocial factors preceding low-back pain as well as stress and physical exertion reported simultaneously with low-back pain. Only stress was associated with low-back pain (Odds Ratio (OR)=2.3; Confidence Interval (CI)=1.3-3.9) while neither physical exertion or any of the psychosocial factors were related to low-back pain. A possible pathway connecting emotional demands of clients to low-back pain through the mediation of stress was suggested.
