Is inadequate health literacy associated with worse health outcomes among Chinese individuals with depression?

Abstract

Inadequate health literacy is a risk factor for poorer outcomes across various conditions. The present study examined the level of health literacy, as measured by the Single Item Literacy Screener (SILS), and its association with a range of physical and mental outcomes [e.g. health-related quality of life, depression, anxiety, well-being, body mass index (BMI)] among individuals with depression in Hong Kong. A total of 112 individuals with depression were recruited from the community and invited to complete a survey. Among the participants, 42.9% of them were classified as having inadequate health literacy as screened by the SILS. After adjusting for significant sociodemographic and background variables, participants with inadequate health literacy had significantly poorer health-related quality of life and well-being, and had higher scores in depression, anxiety and BMI compared with those with adequate health literacy. Inadequate health literacy was associated with a range of negative physical and mental outcomes among individuals with depression. Interventions promoting the health literacy level of individuals with depression are highly warranted.
