Exploring the Relationship Between Supplement Usage and Quality of Life Among Cancer Patients in Jordan: A Cross-Sectional Study

This study explores the use of nutrition supplements by Jordanian cancer patients regarding symptoms of quality of life. It explores the prevalence of the use of nutrition supplements by cancer patients and the related demographic and disease-specific factors. A cross-sectional study was conducted on cancer patients at three major hospitals in Jordan. A total of 220 participants completed structured questionnaires. The EORTC QLQ-C15 scale was used to collect data on supplement usage patterns and quality of life. Chi-square tests and regression analysis were performed to assess the association between supplement use and QoL outcomes. Supplement use was noted in 65.9% of participants; the most used supplements were vitamin D, calcium, and omega-3. Supplement use was significantly associated with age, gender, income, and education level but showed a positive association between supplement use and improved QoL (<i>p</i> = 0.028). The findings suggest that the use of supplements is associated with improved quality of life among cancer patients in Jordan. It is important to consider integrating patient education and professional guidance regarding safe supplement use into cancer care. Further, longitudinal studies are needed to generalize these findings and to explore the long-term effect of supplements on QoL.
