Association of Social Network with Physical Function Among Community-Dwelling Older Adults in Rural Thailand: A Cross-Sectional Study.

Purpose: As the number of older adults in society increases, their social roles and networks, as well as their physical function, decrease. This study aimed to clarify the association between social networks and physical function among people aged ≥ 60 years in rural Thailand. Patients and Methods: This cross-sectional study was conducted in the Photharam District, Ratchaburi Province, Thailand. Participants were required to be at least 60 years old and be able to walk to the health center. Social networks were surveyed using the Thai version of Lubben Social Network Scores-6. Four physical function measures, namely hand grip strength, five-times-sit-to-stand test, timed up-and-go (TUG) test, and one-leg standing, were considered. Regression analysis was conducted with Lubben Social Network Scores-6 as the dependent variable and the four types of physical function as independent variables. Results: A total of 497 older adults aged 60 years or more were enrolled; 82 were males, and 412 were females. The mean Lubben Social Network Scores-6 was 14.9 ± 5.7. Only the TUG test was associated in a single and multiple regression analysis with the Lubben Social Network Scores-6 as the dependent variable and the four physical function assessments as independent variables. Conclusion: The TUG test assessed the smoothness of normal standing and walking, which are essential physical functions for maintaining a social network and meeting people. This suggests a relationship between physical function and social network.
