Factors Associated With Quality of Life Among Colorectal Cancer Patients: Cross-Sectional Study

Abstract

Introduction Colorectal cancer is a chronic condition that affects a substantial proportion of the global population. Ensuring a satisfactory quality of life (QoL) for these patients is, therefore, of critical importance. Objective To examine the relationship between sociodemographic, economic, lifestyle, and health-related variables and quality of life in patients with colorectal cancer receiving treatment at a leading health institution in Medellín, Colombia. Methods This cross-sectional study included all patients aged 18 years and older who were diagnosed with colorectal cancer and treated at the VIDA Clinic Foundation in 2022. Descriptive and bivariate analyses were conducted to characterize the population and explore factors associated with QoL, as assessed using the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) scale. The Mann-Whitney U and Kruskal-Wallis tests were applied to compare median values across variables. A Generalized Linear Model (GLM) with a Gamma family distribution and identity link function was used to identify explanatory variables influencing QoL. Regression coefficients and 95% confidence intervals were calculated. Results A total of 126 patients with colorectal cancer were evaluated, of whom 60.3% were women, with a median age of 61.5 years. The regression model identified poor sleep quality, lack of financial support, dissatisfaction with income, and unemployment as significant factors negatively associated with QoL, after adjusting for sociodemographic variables. Conclusion This study provides an initial exploration of health-related QoL in a Colombian population diagnosed with colorectal cancer. The findings highlight the critical influence of both health-related and socioeconomic factors on patients' QoL. A holistic approach to addressing these dimensions could enhance patient care and inform more effective support strategies.
