The mediation effect of health literacy on social support and health lifestyle of patients with chronic diseases

Previous studies have identified the antecedents of the lifestyle of many patients with chronic diseases. However, the mechanism of social support affecting the lifestyle of patients with chronic diseases is unclear, and the role of health literacy in social support affecting the lifestyle of patients with chronic diseases has not been found. Therefore, this study aims to explore the status quo of social support, health literacy and healthy lifestyle of patients with chronic diseases in China and the relationship among them. Through convenient sampling, 356 patients with chronic diseases were surveyed using a health promoting lifestyle scale, a chronic disease patients' health literacy scale and a social support scale. There was a pairwise positive correlation between social support, health lifestyle and health literacy (R = 0.397,0.356,0.556, P < 0.01). After controlling gender, age and education level, it is found that social support has a positive impact on health lifestyle, and health literacy plays an intermediary role between social support and health lifestyle, accounting for 45.78 % of the total effect. To promote the healthy lifestyle of patients with chronic diseases and delay the development of the disease, we should strengthen social support for patients with chronic diseases; We should simultaneously take various measures to improve their health literacy.
