Abstract

Objective: This study aims to explore the relationship between sleep disorders and cognitive function in elderly migrants, and to analyze the mediating roles of family integration and the digital divide in this relationship. The study provides theoretical foundations and practical guidance for the health management of elderly migrants. Methods: A cross-sectional survey was conducted, involving 300 elderly migrants as subjects. Data were collected using the Pittsburgh Sleep Quality Index (PSQI), Montreal Cognitive Assessment (MoCA), Family Integration Scale, and Digital Skills Scale. Data analysis was conducted using SPSS 26.0 for descriptive statistics and correlation analysis, and AMOS 21.0 was used to construct a structural equation model for mediating effect analysis, exploring the mediating roles of family integration and the digital divide in the relationship between sleep disorders and cognitive function. Results: The study found a significant negative correlation between sleep quality and cognitive function (r = -0.45, p <0.01), while family integration was positively correlated with cognitive function (r = 0.20, p <0.05). Sleep quality was positively correlated with the digital divide (r = 0.35, p <0.01). The structural equation model analysis indicated that family integration and the digital divide played significant mediating roles in the relationship between sleep disorders and cognitive function. Conclusion: Family integration and the digital divide serve as dual mediators in the relationship between sleep disorders and cognitive function in elderly migrants. Improving family integration and reducing the digital divide can effectively enhance their sleep quality and cognitive function. It is recommended that policymakers and social service agencies strengthen family support and digital skills training for elderly migrants to improve their overall health, especially in terms of sleep quality and cognitive function.
