Poor sleep quality and physical performance in older adults

Poor sleep quality and physical performance in older adults
Poor sleep quality and physical performance in older adults
Objectives: this study aimed to examine the association between sleep quality and physical performance among a group of UK community-dwelling older adults, according to sex.

Methods: sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Physical performance was assessed using a short physical performance battery (SPPB), a timed up-and-go, and a hand-grip strength test.

Results: of 591 eligible study members, 401 completed the PSQI. In regression analyses, men who reported poor sleep quality were significantly more likely to have a poor SPPB score, even after adjustment for confounding factors (OR=2.54, 95% CI 1.10-5.89, p=0.03). The direction of the relationship was reversed among women, where those who reported poor sleep were less likely to have a low SPPB score (OR=0.36, 95% CI 0.15-0.85, p=0.02). Poor sleep quality was associated with poorer hand-grip strength among women (regression coefficient=-0.34 z-score, 95% CI -0.64, -0.04, p=0.03), but this relationship was not observed among men (regression coefficient=0.28 z-score, 95% CI -0.01, 0.57, p=0.06).

Conclusion: we found evidence of an association between poor sleep quality and poorer physical performance in older adults, though there appear to be important sex differences.

Results: of 591 eligible study members, 401 completed the PSQI. In regression analyses, men who reported poor sleep quality were significantly more likely to have a poor SPPB score, even after adjustment for confounding factors (OR=2.54, 95% CI 1.10-5.89, p=0.03). The direction of the relationship was reversed among women, where those who reported poor sleep were less likely to have a low SPPB score (OR=0.36, 95% CI 0.15-0.85, p=0.02). Poor sleep quality was associated with poorer hand-grip strength among women (regression coefficient=-0.34 z-score, 95% CI -0.64, -0.04, p=0.03), but this relationship was not observed among men (regression coefficient=0.28 z-score, 95% CI -0.01, 0.57, p=0.06).
