The role of psychosocial factors in the course of pain-a 1-year follow-up study among women living in Sweden.

The understanding of the associations between psychosocial factors and persistent pain and their impact on the course of pain among women is crucial to identify risk populations and prevent long-term pain from developing. The aim of the study was to investigate the course of pain among women and the psychosocial factors associated with it. The study was a 1-year follow-up (FU) among 2,300 women in the general population of Sweden. Sociodemographic and psychosocial factors were analyzed in relation to the course of pain, assessed as the presence of pain during the last 3 months at baseline (BL) and at FU. Thirty-three percent of the women with no pain at BL and 77% of those with pain at BL reported pain at FU. Compared to the pain-free women, those who developed pain at FU reported lower social support and physical quality of life (QoL) and worse mental health. Women with sustained pain were older and reported worse mental health, lack of social support, and lower levels of QoL compared to those who recovered from pain. In the multiple logistic regression analyses, only post-traumatic stress symptoms were associated with the development of pain at FU. Number of pain locations and pain duration at BL and physical QoL were associated with sustained pain. Moreover, social support was identified as a protective factor against sustained pain. Pain is persistent or recurrent in a general female population. The results indicate that psychosocial factors do not work as primary predictors in the course of pain and might be better understood through indirect processes by limiting the individual's resources for handling pain in a functional manner.
