Abstract

Objectives

To investigate the relationship between insomnia (INS) combined with chronic musculoskeletal pain (MSP) in postmenopausal women and its characteristics regarding MSP, menopausal and mood symptoms, sleep and quality of life (QOL).

Methods

A cross-sectional control study in 4 groups of postmenopausal women: control (n = 15), MSP (n = 15), INS (n =15) and INS + MSP (n = 17). Sixty-two participants completed questionnaires and had blood collected, and 43 underwent polysomnography.

Results

INS was associated with increased anxiety (P = 0.04) and sleep fragmentation (P = 0.02); worse MSP severity (P = 0.00), MSP interference with daily function (P = 0.00), higher pain intensity at midday (P = 0.02) and menopausal symptoms (P = 0.00); and reduced QOL (P = 0.00). MSP was associated with increased anxiety (P = 0.02) and menopausal symptoms (P = 0.00), and reduced QOL (P = 0.05). In the whole sample, depression symptoms were higher but no statistical differences were found between groups (P = 0.47). Worse QOL was associated with both higher depressive symptoms (P = 0.01) and worse pain interference (P = 0.02)

Conclusions

INS + MSP was related to higher menopausal and anxiety symptoms, more sleep fragmentation and complaints of MSP severity and interference, more pain sites and worse QOL. The presence of INS was associated to more MSP. Sleep management is essential in women who have developed chronic MSP.
