introduction Health-seeking behaviour influences healthcare services utilisation and self-care. Delay in timely and appropriate care when one is ill may lead to rise in morbidity and mortality. This study aimed to describe the health-seeking behaviour among adults in Malaysia with acute illness and oral health problems. Materials and Methods We analysed data of adults aged 18 years and over from the National Health and Morbidity Survey 2019. This cross-sectional survey used a complex study design with a two-stage stratified cluster sampling. Face-to-face interviews were conducted using a validated questionnaire. Descriptive analysis was performed using STATA Version 14.0 software. Results [Refer to Poster]. Discussion / Conclusion Our findings revealed that more than one-third of the adults did not seek care when ill despite a quarter of them perceiving care was needed. Promoting responsible self-medication is important(4) to empower people in self-care. Nevertheless, seeking appropriate care when needed is equally important.
