Abstract
Background: Declines of cognitive function (CF) and physical function (PF) are two irreversible health conditions linked closely to the elderly’s health-related quality of life (HRQoL). Health literacy (HL) represents the abilities for individuals to cope with health issues, and shows a positive effect on HRQoL. This research hypothesized that HL may act as a partial mediator between CF together with PF and HRQoL.
Objective: This research aimed to determine the model of relationships of CF and PF with HL that contributes to the HRQoL of older adults in Hong Kong
Methods: Older adults aged 50-80 years old were recruited through social media and community centers from March to July 2021. HL was assessed using the 12-item Short-Form Health Literacy Survey Questionnaire (HLS-SF12). CF was assessed using Montreal Cognitive Assessment (MoCA). PF was assessed using the Senior Fitness Test (SFT). HRQoL was assessed using the 12-item Short Form Health Survey version 2 (SF-12v2). The mediating effects of HL was tested with path analysis based on the proposed theoretical model.
Results: Totally, 490 older adults completed the survey. Results for direct effects indicated that CF significantly predicted PF (β=.115, SE=.012, p <.001), PF significantly predicted HL (β=.101, SE=.022, p<.001), and HL significantly predicted HRQoL (β=.457, SE=.049, p<.001). Meanwhile, PF significantly predicted HRQoL directly (β=.150, SE=.025, p<.001) as well as indirectly (β=.046, 95% CI [.028, .067]).
Conclusions: A mediational model was hypothesized and tested in the current study to explore the relationships of CF and PF with HL that contributes to the HRQoL. These findings partially supported the hypotheses, highlighting the effect of health literacy on improving older adults’ HRQoL under the influences of both CF and PF together. This study may contribute to further empirical research and health promotion intervention programs that aim to improve HL that leads to better quality of life for the elderly population.
