Abstract

Objective To explore the mediating effect of anxiety in perimenopausal women between sleep disturbance and life quality.

Results The scores of sleep disorder, anxiety and quality of life were (14.31±2.75), (49.94±9.58) and (54.02±4.50) in perimenopausal women.There was a positive correlation between anxiety and sleep disorder (r=8.32, P<0.01), and a negative correlation between anxiety, sleep disorder and quality of life (r=-5.37, -5.62, P<0.01). Anxiety had a mediating effect between sleep disorders and quality of life.The intermediate effect value was -0.201, accounting for 32.4%.
