Supplement Use and Its Impact on Daily Life of Cancer Patients: A Cross Sectional Study

Abstract

Abstract Purpose This cross-sectional study aimed to investigate the prevalence and characteristics of supplement usage among cancer patients and explore its potential associations with anxiety, excessive daytime sleepiness, and overall quality of life. Methods Cancer patients receiving specific care at Hôtel Dieu de France University Hospital, Beirut, were enrolled between April and June 2023. In face-to-face interviews, participants were asked to complete a questionnaire consisting of sociodemographic information, supplement usage details, and cancer-related variables. Three validated surveys (Epworth Sleepiness Scale, GAD-7 and EORTC-QLQ-C15-PAL) were employed to assess excessive daytime sleepiness, anxiety and overall quality of life. Statistical analyses, including chi-square tests, t-tests, and multiple regression models, were conducted to examine associations between supplement use and other variables. Results 202 participants were interviewed. 52% reported regular use of supplements following their cancer diagnosis, with vitamin D being the most commonly used supplement. Using multivariate logistic regression, supplement use was associated with being female, having lower educational levels, having a longer duration since cancer diagnosis and having a poor overall quality of life. The multivariate logistic regression showed no significant correlation between supplement use and excessive datime sleepiness and anxiety. Conclusion This study highlights a high prevalence of supplement usage among cancer patients in Lebanon, indicating a rising interest in alternative therapies aimed at enhancing quality of life. Larger prospective studies are needed to assess the relation between supplement intake and excessive daytime sleepines and anxiety and establish clear guidelines pertaining to supplement use in cancer patients.
