Predictors and health impacts of Ramadan intermittent fasting among patients with sickle cell disease.

Introduction: Ramadan fasting constitutes a form of intermittent fasting, and it is a religious obligation for healthy adult Muslims; however, there is a lack of comprehensive guidance for individuals diagnosed with sickle cell disease (SCD). This study seeks to identify predictors of fasting capability and investigate the effects of fasting among this patient population. Participants and methods: This cross-sectional study enrolled adult Muslim patients with SCD from Saudi Arabia. Data were collected through direct interviews using a structured questionnaire with four sections. Results: A total of 320 patients with SCD were evaluated, with a mean age of 32.6 years (SD ± 11.01) and the majority were females (63.1%). Among these participants, 214 (66.9%) observed Ramadan intermittent fasting (RIF) while 106 (33.1%) did not observe the fasting month or had interrupted fasting. Participants having secondary and university education were nearly twice as likely to fast the entire Ramadan ( Conclusion: The effects of observing RIF on individuals with SCD are generally subtle during the month but more significant in the post-fasting phase. The capacity to predict an individual's ability to fast and likelihood of post-fasting complications is substantially influenced by a range of sociodemographic factors such as education level as well as clinical variables, including frequency of annual hospitalizations, emergency room visits, intensive care unit admissions, occurrences of acute chest syndrome, and the presence of thrombocytosis. A Comprehensive evaluation of these factors will provide enhanced guidance for medical practitioners, facilitating more informed and insightful decisions regarding patient fasting recommendations.
