Inflammatory bowel disease is a chronic disease characterized by digestive symptoms with an increasing incidence and prevalence. It is well established its impact on the quality of life of patients and their main caregivers but no study has yet considered the consequences of IBD on cohabitants with no direct involvement in patient`s care. Our aims were to analyze quality of life in cohabitants of people with IBD and identify potential related factors. 


We conducted a cross-sectional study that included patients with IBD and their house-hold members. Participants were recruited from a period of two months from patients attending the IBD unit of our hospital. Inclusion criteria were a definite diagnosis of IBD and household members living in the same house for a period of 1 year or more. Exclusion criteria were an age <18, refusal to participate or subjects unable to fulfill the questionnaires.

Demographic data was obtained for patients and household members. 

IBD activity was assessed by using the Partial Mayo Score and the Harvey-Bradshaw score. Other relevant information regarding the prior and current state of the disease was collected.

Quality of life was assessed in the case of the patients with the Inflammatory Bowel Disease Questionnaire (IBDQ-32) and for the household members we used the Household Members Quality of Life-Inflammatory Bowel Disease (HHMQoL-IBD) questionnaire. 


We included 22 patients with UC, 32 patients with CD and 2 patients with indeterminate colitis and 82 household members. Both groups had similar sociodemographic characteristics. 

The univariate analysis of the quality of life of cohabitants showed a significant association of HHMQoL-IBD and IBDQ-32 score in their relatives (p<0.0001) (Figure 1), last CRP (p=0.043), number of disease flares in the last year (p=0.04), extraintestinal diseases (p=0.01) and particularly articular disease (p=0.04). 

Cohabitants of patients with CD had significantly lower HHMQoL-IBD than UC ones (53 ± 18 vs. 62 ± 23; p=0.049). 

Among cohabitants of patients with UC and CD, patient’s CRP in the last control was related to HHMQoL-IBD score (p=0.043 and p=0.04 respectively). 

In a linear multiple regression analysis, IBDQ-32 score (p<0.0001) in patients and the presence of extraintestinal disease (p=0.048) were independent predictors of cohabitant’s quality of life, and particularly articular disease.

Quality of life in household members of patients with IBD is related to patient’s quality of life and extraintestinal conditions related to the disease. Our study shows how important is to analyze and act in the patient’s whole environment, taking into consideration not only clinical variables but also the relational conditions and impact of the disease.
