Health literacy, knowledge, household disposal, and misuse practices of antibiotics among UAE residents: a nationwide cross-sectional study.

Background: The study aimed to evaluate health literacy, knowledge, household disposal, and misuse practices of antibiotics among the United Arab Emirates (UAE) residents.

Research design and methods: An observational cross-sectional study was conducted between May 1^st and August 31^st, 2022. The study encompassed a sample of 1074 participants.

Results: Participants involved in a medical field (OR: 1.98, 95% CI: 1.45-2.69, p < 0.001) were more likely to have adequate health literacy. Most participants rarely (n = 315; 29.33%) or sometimes (n = 292; 27.19%) sought help from a doctor or pharmacist with reading the instructions and leaflets of antibiotics. A bachelor`s degree was associated with a reduced odds ratio of self-medication with antibiotics (OR: 0.46, 95% CI: 0.29-0.75, p = 0.002). Only 10.61% of unneeded antibiotics were returned to the pharmacy, 79.42% were disposed of at home and 10% were disposed of using other disposal practices.

Conclusions: Higher levels of adequate health literacy were observed in those involved in the medical field and those with higher educational levels. The prevalence of self-medication with antibiotics among the UAE population was low. These findings highlight the importance of improving health literacy, promoting responsible antibiotic use, and encouraging proper disposal practices among the population.
