Prevalence and risk factors of low health literacy in residents of Anhui province: A cross-sectional survey

This survey aimed to evaluate the prevalence of low health literacy and correlations of demographic characteristics with low health literacy risk in residents of Anhui province. A total of 5120 residents of Anhui province were interviewed in this cross-sectional survey, and 4816 (94.1%) gave valid responses. Sociodemographic characteristics were collected. Health literacy and its 3 subscales, including basic knowledge and concepts, lifestyle, and health-related skill, were assessed. Low health literacy was defined as <80.0% of the total score or score of each subscale. Mean total health literacy score was 62.7±17.2 (maximum 100 points), and was 31.5 ± 9.0 (maximum 47 points), 17.0 ± 4.8 (maximum 28 points), and 14.2 ± 4.1 (maximum 25 points) in terms of basic knowledge and concepts score, lifestyle score, and health-related skill score, respectively. The prevalence of low health literacy was 81.4%, and was 71.3% in terms of basic knowledge and concepts subscale, 87.9% with regard to lifestyle subscale, and 86.3% in view of health-related skill subscale. In addition, older age (P = .001), male (P < .001), decreased education level (P < .001), lower annual household income (P < .001), and location at rural area (P < .001) associated with increased risk of low health literacy. Moreover, multivariate logistic regression revealed that male, lower education level, and location at rural area were independent risk factors of low health literacy (all P < .05). The prevalence of low health literacy is high in residents of Anhui province, and male, lower education level, as well as location at rural area are independent risk factors of low health literacy.
