[Association between life space and health literacy in community-dwelling older adults].

Aim: To examine the association between health literacy (HL) and life space in community-dwelling older adults.

Methods: In this cross-sectional study, we analyzed 210 community-dwelling older adults (mean age: 74.6 years, women: 63.8%). Health literacy was measured using the 14-item Health Literacy Scale (HLS-14). The 14 items consist of 5 items for functional HL (FHL), 5 items for interactive HL (CHL), and 4 items for critical HL (IHL). We calculated the total score, FHL score, CHL score, and IHL score. Life space was measured using the life-space assessment (LSA). A linear regression model was used to analyze the association between the HLS-14 score and LSA score. We adjusted for variables associated with the LSA score.

Results: The FHL score was significantly associated with the LSA score (crude model: β = 1.40, p < 0.01, adjusted model: β = 1.11, p = 0.01). However, the total score, IHL, and CHL were not significantly associated with the LSA score.

Conclusions: A higher FHL is significantly associated with a greater larger life space in community-dwelling older adults. This finding may help elderly people maintain a greater life space which will help them to improve their HL while also making it possible for them to obtain easy-to-understand information.
