Advanced Age Does Not Negatively Impact Health-Related Quality of Life in Inflammatory Bowel Disease

Abstract

Background: Health-related quality of life (HRQoL) is significantly impacted in patients with inflammatory bowel disease (IBD). Many studies have assessed HRQoL in patients of all ages, and few focus on the elderly.

Aim: To determine the influence of advanced age (> 65 years) and age at diagnosis on patients with IBD.

Methods: This is a retrospective study of prospectively collected data from a single IBD tertiary referral center. Patients had disease activity indices [Harvey-Bradshaw index (HBI), Ulcerative Colitis Disease Activity Index (UCDAI), and Short Inflammatory Bowel Disease Questionnaire (SIBDQ)] recorded during every clinic visit. Three groups of patients: > 65 years, 41-64 years, and < 40 years with > 5 SIBDQ entries were included. Influence of disease type, disease duration, extent of involvement, and comorbidities such as cardiovascular (CV) disease, pulmonary disease, diabetes mellitus (DM), and psychological disorders were noted as confounders. Statistical analysis was performed using ANOVA, Pearson correlation, and logistic regression model.

Results: Disease severity indices significantly affected SIBDQ score in both Crohn's disease (CD) and ulcerative colitis (UC) (p < 0.001 for HBI in CD, p < 0.001 UCDAI in UC). Disease extent (p = 0.011) and psychological disorders (p < 0.001) significantly affected SIBDQ score in CD. Chronological age, age at diagnosis, disease duration, number of clinic visits, CV disease, pulmonary disease, and DM were not significant predictors of SIBDQ score (p > 0.05).

Conclusions: HRQoL was negatively influenced by disease extent and psychological disorders in CD but not in UC patients. Advanced age was not a predictor of poor HRQoL in both CD and UC.
