ABSTRACT
BACKGROUND: Dry eye disease (DED) is characterized by loss of homeostasis of the tear film or failure to produce sufficient amounts of tears to moisturize the eyes. The condition has been associated with several preventable risk factors. Objective: The objective of this study is to calculate the prevalence of dry eye and determine the associated risk factors among adults and children in Saudi Arabia. Methods: This is a cross-sectional study targeting all Saudi populations, including all the regions of Saudi Arabia. The Ocular Surface Disease Index (OSDI) and the five-item Dry Eye Questionnaire (DEQ-5) were used for data collection. Data were collected using an online form that was distributed through social media. Results: A total of 541 responses were analyzed. The OSDI scores showed that females represented 70.9%, and the age group of 20-40 years represented 59.7%. The prevalence of DED, including all severity levels, was 74.9%. The distribution across levels was as follows: mild cases at 26.2%, moderate cases at 18.2%, and severe at 30.4%. On the other hand, DEQ-5 has shown a prevalence of 37% among the pediatric age group. Several risk factors have been significantly associated with adults' dry eye, including low humidity (P-value=0.002), reading, driving, or watching electronic screens for extended durations (P-value=0.019), autoimmune diseases (P-value=0.033), and undergoing eye procedures (P-value-0.013). Conclusion: The current study reports a high prevalence rate of dry eyes among the Saudi population. Reading, driving, and using electronic screens for an extended period were found to be associated with the severity of DED. Prospective studies should focus on the epidemiology of the disease, which will provide evidence for better preventive and therapeutic measures.
ABSTRACT
PURPOSE: Epilepsy is one of the most common neurological disorders, with a national prevalence of 6.54/1000. The majority of the patients are adolescents and at risk of experiencing a seizure in school. Consequently, schoolteachers would be among the first health care providers. Thus, teachers' knowledge and practice are imperative for the students' safety and development. We aimed to assess the knowledge of epilepsy and seizure first aid among teachers at all educational levels in Jeddah, Saudi Arabia. METHOD: A cross-sectional study using a self-administered validated questionnaire was distributed to teachers to assess their necessary demographic data and their knowledge about epilepsy and seizure first aid by using Chi-square test to find significant associations. RESULTS: Our sample included 822 teachers, 54.1% of the respondents were male, and 45.7% female. The majority of participants had moderate knowledge of epilepsy and lacked first aid training. Most participants recognized epilepsy as a neurological disorder, and 42.2% have witnessed a seizure in school. Our study showed a significant relationship between knowledge score and qualification (P-value = 0.037) as well as knowledge score and witnessing a seizure (P-value = 0.046). CONCLUSION: The knowledge score shows that teachers in Jeddah have moderate knowledge of epilepsy, and approximately one-tenth have taken first aid training. We recommend educational campaigns on epilepsy and first aid courses targeting students and teachers in schools.
