Do Health Literate Older People Have Fewer Depressive Symptoms? Evidence from the Urban Areas of Western China.

Background: Previous research has indicated that health literacy has a good influence on the mental health among older adults. The current study aims to determine whether health literacy is linked to depressive symptoms in older adults in west China, and tries to detect the mechanisms underlying the linkage between health literacy and depressive symptoms in the Chinese context.

Methods: Study data were obtained from a cross-sectional ageing health literacy survey conducted in 2017 in Western China, and 812 urban individuals aged 60 and older were selected.

Results: Health literacy was associated with fewer symptoms of depression; additionally, older adults who reported harmonious family and filial piety, those with greater self-rated health, and those with a higher level of life satisfaction tended to have fewer depressive symptoms, whereas older individuals who reported a poor financial status and those with functional impairment had more depressive symptoms.

Conclusions: The findings indicate the protective role of health literacy against depressive symptoms among urban older adults. In addition, the findings also indicate the potential impact of financial strain and functional impairment on the development of depressive symptoms and show that other factors including a harmonious family, filial piety, self-rated health and life satisfaction are generally protective against depressive symptoms. Specific evidence is presented for the national action plans and public health strategies needed to reinforce and promote health literacy in the Chinese context. The current results also suggest that health education and promotion programs designed to strengthen financial assistance, functional improvement, family relationships, life satisfaction and self-rated health should gain a growing importance on the health agenda. Future longitudinal studies, mediation or moderator models, and structural equation modeling would be needed to identify a causal relationship, the moderating or mediating effect, and the possible pathways underlying the linkage between health literacy and depressive symptoms, respectively.
