Background: The complexity of demands regarding health literacy in present society requires knowledge and competences within health care, disease prevention, and health promotion in order to retain and obtain good health. Health literacy is mentioned in the literature to be part of the social determinants of health, however the mechanisms behind this association are still unclear. The objective of the present study was to investigate the effect of social support and living alone on health literacy.
Methods: A cross-sectional study was conducted based on a randomly selected sample of 15,728 Danish citizens aged 25 or older. Information on health literacy, social support and living alone was gathered through a nationwide questionnaire during December 2016 and February 2017 and linked to administrative registry data. Multinomial regression was used to assess associations.
Results: Adequate health literacy was seen in 60.3% of the respondents and more men (59.5%) than women (40.5%) had inadequate health literacy. Lower social support was associated with higher inadequate health literacy levels and problematic health literacy among respondents with lower opportunity for practical help when being ill. Men, younger respondents, and respondents with lower educational attainment had higher risks of problematic and inadequate health literacy. No associations were found between living alone and health literacy.
Conclusions: The results from this study shed light on the mechanisms of social context and its relation to health literacy. But it also gives new insight to mechanisms behind the relationship between social support and health outcomes. We suggest that health literacy might be on the causal pathway between functional social support and health. We further recommend that future studies on social relationships and health should include measures of health literacy and multidimensional measures of social support.
