Project Abstract

 

Health literacy is an important topic in today’s health care environment as evidenced by the World Health Organization urging countries to take action in improving health literacy in populations so that their citizens are enabled to proactively take charge of their health and push governments to address health issues (WHO 2019). There have been very few research on the relationship between health literacy and quality of life. The research aim is to determine the model of correlates of cognitive and physical functions and health literacy that contributes to the health-related quality of life in a cross sectional sample of older adults. A secondary purpose is to have in-depth understanding between health literacy status and health-related quality of life of older adults in Hong Kong. We hypothesized that health literacy should act as a partial mediator between cognitive and physical functions and health-related quality of life. The initial quantitative analysis will involve 800 older adults aged 50-80 years old recruited by quota sampling through social media, personal approach or telephone. Participants will complete two separate 1-hour tests within 2 weeks. First data collection session will include assessments of physical activity readiness, cognitive function, and health literacy level. Second data collection session will involve physical fitness testing and a survey on health-related quality of life. For the qualitative phase, semi-structured interviews of focus groups and personal interviews (n=30) with elderly, care-givers, and nurses of geriatric care will be conducted within a month’s time. Approval for human subjects will be attained by the University Research Ethics Committee. Health literacy will be assessed by the 12-item Short-Form (HLS-SF12) of the European Health Literacy Questionnaire. Cognitive function will be assessed by the Mini Mental State Exam (MMSE; Folstein, Folstein, & McHugh, 1975). Physical function will be assessed using the Senior Fitness Test (SFT, Rikli & Jones, 2001). Health-related quality of life (HRQoL) will be assessed using the SF-12v2 physical health summary subscale (Lam et al., 2010). The mediating effects of health literacy will be tested with path analysis based on the proposed theoretical model. Interview responses will be content analyzed to identify relevant salient factors influencing the health literacy levels and health-related quality of life of older adults.
