Abstract
BACKGROUND: (1) Health literacy of riverine populations is inadequate. (2) Health literacy was not associated with quality of life. (3) Health literacy was associated with sociodemographic aspects of riverine populations. (4) Quality of life was related to the sociodemographic profile of riverine populations. to analyze functional health literacy and health-related quality of life in riverine populations using primary care services, according to sociodemographic variables. an analytical, cross-sectional study with 312 users of the riverine family health strategy. Data were collected using a health literacy test, the 12-item Health Survey, and a socioeconomic questionnaire adapted by the researchers. Spearman correlation, Mann-Whitney and Kruskal-Wallis tests, as well as multiple logistic regression were performed, considering p≤0.05. 65.7% presented inadequate functional health literacy, with higher risk for men (p<0.001), aged 40-49 (p=0.010) and 50-59 years (p=0.031), incomplete (p<0.001) and complete (p=0.024) elementary education, and residing far from health services (p<0.001). Quality of life showed no association with health literacy. However, lower quality of life was related to female gender (p=0.049), incomplete elementary education (p=0.016), use of mobile phones with internet and radio (p=0.013), advanced age (p<0.001), increased number of children (p=0.002), and lower age at the start of work activities (p<0.001). functional health literacy of riverine populations is inadequate and not associated with quality of life. However, both are influenced by the sociodemographic profile.
