To explore the mediating effect of physical function and nutritional status between sleep quality and frailty in rural elderly people based on Gobbens frailty integration model.
From July to September 2023, multi-stage stratified cluster random sampling was used to select the elderly aged ≥60 years old in rural areas of Xinjiang, and questionnaire survey and body measurement were used to investigate the study. AMOS 28.0 software was used to establish the structural equation model (SEM) and test the mediating effect.
(1) Frailty scores of the rural elderly were 40.00 (34.00,46.00), sleep quality scores were 7.00 (5.00,9.00), physical function scores were 9.00 (7.00,10.00), nutrition scores were 13.00 (12.00,14.00); (2) The score of sleep quality of the rural elderly was positively correlated with the score of frailty, and negatively correlated with the score of physical function and nutritional status (r=0.405, -0.222, -0.125, P<0.001). The score of physical function was negatively correlated with the score of frailty, and positively correlated with the score of nutritional status (r= -0.220, 0.216, P<0.001). Frailty score was positively correlated with nutritional status score (r= -0.071, P=0.024); (3) Physical function and nutritional status played a mediating role between sleep quality and frailty, accounting for 15.76% of the total effect.
Physical function status and nutritional status play an intermediary role in the sleep quality and frailty of the rural elderly. Through early identification of sleep problems, physical function status and nutritional status can be improved, delaying or even reversing the occurrence of frailty.
