Abstract

Aim: The aim of present study is to evaluate the factor associated with functional constipation (FC) and determine a normal range of bowel movement (BM) in an Iranian Auto factory’s worker.  

Background: The digestive system may be affected by workplace condition.  Some occupational conditions can effect on bowel habit and FC.

Materials and methods: In this cross -sectional study, 3590 workers who worked in Tehran suburb in 2017 were evaluated. The workers were working at morning or rotatory shifts and in the official and non- official sections. In addition to demographic and stool frequency questions, workers were asked to complete the Rome IV Questionnaire.

Results: The normal range of BM frequency was determined between one and three per day. The BM frequency had a significant association with age (P=0.002), marital status (P=0.024), education (P=0.011), expose to chemical materials (P<0.001) and work section (P<0.001). The total prevalence of FC was 9.7% and among rotatory shift working, was more than the only morning shift working, (10% vs 6%; P=0.02). Independent factors associated with FC were found as age (for 30- 40 years old: OR=1.88; 95% CI (1.20, 3.03) and for ?41 years old: OR=1.91; 95% CI (1.12,3.17)), smoking (OR=1.52; 95% CI (1.20,1.93)) and work section (for Paint section: OR=0.33; 95% CI (0.12,0.87), for Montage section: OR=0.44; 95% CI (0.18,1.10), for Press & Platform section: OR=0.12; 95% CI (0.05,0.37)).

Conclusions: Occupational condition probably makes difference in bowel habit. Rotatory shift, official working and smoking may increase the risk of constipation.
