The relationship between health literacy level and quality of life in bariatric surgery patients

Abstract Background Today, obesity is an important public health problem. In addition to the intervention programmes developed to prevent obesity, the necessity of medical and surgical treatment is increasing with the growing population. This study was conducted to determine the relationship between health literacy and quality of life in patients undergoing bariatric surgery. Methods This cross-sectional study was conducted with the participation of 136 patients aged 18 years and older who underwent bariatric surgery in a general surgery service between January 2021 and December 2023 and whose contact information was available. The survey participation rate was 75.1%. The questionnaire used for data collection consisted of questions about the sociodemographic information of the participants, The European Health Literacy Survey Questionnaire (HLS-EU-Q16) and the Postbariatric Surgery Quality of Life Scale items. Descriptive statistics, Mann Whitney U, Kruskal Wallis H test and Spearman correlation analysis were used to analyze the data. A value of p < 0.05 was considered statistically significant. Results The mean age of the patients who participated in the study was 38.2 ± 10.8 years; mean BMI was 42.3 ± 6.4 before surgery and 29.0 ± 6.2 after surgery. In the study, 44.1% of the patients who underwent bariatric surgery were found to have inadequate/problematic health literacy level. Participants who had less than a bachelor’s degree (p = 0.009) and low income (p < 0.001) had significantly lower health literacy levels. In addition, a moderate positive correlation was found between overall health literacy score and quality of life score (r = 0.252; p = 0.003). Conclusions In conclusion, this study shows that improved health literacy positively affects quality of life in patients undergoing bariatric surgery and that health literacy education should be emphasized in this context. Key messages • The level of health literacy of bariatric surgery patients is a determining factor on quality of life, and therefore health literacy education is important, especially in identified risk groups. • Increased health literacy can have positive results in terms of psychosocial and physical health and improve quality of life after bariatric surgery.
