BackgroundObstructive sleep apnea (OSA) is relatively common in childhood and is characterized by repeated partial or complete blockages of the upper airway during sleep. Children affected by OSA can experience various symptoms including snoring, restless sleep, and behavioral issues such as hyperactivity, impulsivity, and aggression, which interfere with their quality of life. Additionally, OSA can result in serious conditions such as cardiovascular and metabolic diseases. This study aims to determine the level of knowledge and awareness of OSA among parents in the Jeddah region.MethodologyAn observational cross-sectional study was conducted to determine the level of awareness of OSA among all parents in Jeddah, Saudi Arabia. Participants were recruited through social media platforms. The online survey assessed the knowledge regarding the OSA definition, risk factors, associated symptoms, and treatment.ResultsA total of 462 participants were included. Only 16% of participants had a good level of knowledge of OSA, while the remaining 84% had a poor level of knowledge. The mean knowledge score was 15.39 ± 5.8, with a significant difference between occupations (P=0.039).ConclusionOur study reveals that parents in Jeddah, Saudi Arabia have a low level of knowledge about pediatric OSA, with only 16% demonstrating good knowledge and less than half recognizing the definition of OSA. This lack of knowledge could lead to delays in diagnosis and treatment, negatively impacting children's health and academic performance. Common symptoms of OSA reported by parents were restless sleep, mouth breathing, and snoring, but bedwetting and hyperactivity were poorly recognized. Adenoids, allergic sinusitis, enlarged tonsils, asthma, and obesity were identified as risk factors for OSA. Improving parental awareness of OSA through public campaigns, doctor consultations, and education programs is crucial. Further studies are needed to assess the effectiveness of these interventions.
