Exploring Health Literacy among Adults with Hidradenitis Suppurativa

Introduction: Health literacy plays an important role in the management of chronic and debilitating skin diseases like hidradenitis suppurativa (HS). Adequate health literacy empowers patients to understand their disease, manage it effectively, and make informed decisions about their health. Exploring the interplay between health literacy and HS is essential to improve healthcare outcomes in this population. This study aimed to assess the prevalence of limited health literacy among HS patients and its associated factors which has never been studied before. Methods: In this epidemiological cross-sectional study, data were collected via a population-wide survey within the Lifelines Cohort Study in the Netherlands. Health literacy of participants with HS was compared to non-HS controls. The health literacy was measured using six validated questions covering functional, communicative, and critical health literacy. Associations between the characteristics of the HS group and limited health literacy were examined. Results: Out of 56,084 adult respondents, 1,156 participants with HS were identified. The prevalence of limited functional health literacy was 24.5% in the non-HS group and 26.4% in the HS group. Our findings indicate that limited health literacy among HS patients is associated with higher body mass index (BMI) (26.9 vs. 25.8) (OR: 0.969, 95% CI: 0.941-0.998), lower education level (34.5% vs. 19.9%) (OR: 0.495, 95% CI: 0.350-0.701), lower socioeconomic status (-0.68 vs. -0.58) (OR: 1.194, 95% CI: 1.029-1.386), and more severe disease stage according to the Hurley stage (33.0% vs. 25.8%) (OR: 1.400, 95% CI: 1.005-1.952). Conclusions: Our study highlights the importance of addressing health literacy in HS patients, given the high prevalence of limited health literacy among this group and associations with higher BMI and more severe disease stage. Limited health literacy may contribute to poorer health outcomes, suboptimal healthcare utilization, elevated healthcare costs, and health disparities. Targeted interventions to improve health literacy could enhance care quality and outcomes for HS patients.
