Knowledge Assessment Regarding the Differences Between Hypothyroidism and Hyperthyroidism Among Saudi Arabia's Adult Population.

Introduction Worldwide, thyroid diseases are among the most prevalent endocrine disorders. According to the Saudi Arabian Ministry of Health (MOH), many thyroid disease cases remain undiagnosed and, as a result, are not treated because the patient has no symptoms or is unaware of them. Hence, this study aims to assess the knowledge about hypothyroidism and hyperthyroidism among Saudi Arabia's population. Methodology A cross-sectional survey was conducted among Saudi adults in five randomly selected regions in Saudi Arabia from December 2022 - January 2023. An Arabic self-administered questionnaire was sent to randomly selected participants via an online link. The questionnaire was composed of four parts: Sociodemographic; knowledge related to hypothyroidism and hyperthyroidism diseases and their differences; knowledge about the thyroid gland in terms of functions and causes of thyroid dysfunction. The Statistical Package for Social Sciences was used for data analysis. Results Out of 996 participants (66.2% women), 70.1% knew the function of the thyroid gland, 66.4% knew that women are more susceptible to thyroid disease, and 49.5% knew the association between thyroid dysfunction and heart disease. Female sex, higher education, and old age were associated with good knowledge, and no differences were evident regarding nationality and residence. The results showed inadequate awareness regarding thyroid diseases in Saudi Arabia, with some parts of this population being very clearly below average. Conclusion Knowledge regarding thyroid disorders was sub-optimal in Saudi Arabia; older women with higher education had the best knowledge. With even larger samples, we recommend that future studies be made to develop clear and decisive public health strategies that can be implemented at once.
