The aim of the present study was to evaluate the factors associated with functional constipation (FC) and to determine a normal range of bowel movement (BM) in an Iranian Auto factory's workers.
The digestive system may be affected by workplace conditions. Some occupational conditions can affect the bowel habit and FC.
In this cross-sectional study, 3590 workers who worked in Tehran suburb in 2017 were evaluated. The workers worked in 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.
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), exposure to chemical materials (P<0.001), and work section (P<0.001). The total prevalence of FC was 9.7% which was greater among rotatory shift working than among only morning shift workers (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)).
Occupational condition may make a difference in bowel habit. Rotatory shift, official working, and smoking may increase the risk of constipation.
本研究旨在评估与功能性便秘（FC）相关的因素，并确定伊朗一家汽车工厂工人的正常排便范围。
消化系统可能会受到工作场所条件的影响。一些职业条件会影响排便习惯和功能性便秘。
在这项横断面研究中，对2017年在德黑兰郊区工作的3590名工人进行了评估。这些工人从事早班或轮班工作，分布在正式和非正式部门。除了人口统计学和排便频率问题外，还要求工人完成罗马IV问卷。
确定的正常排便频率范围为每天1至3次。排便频率与年龄（P = 0.002）、婚姻状况（P = 0.024）、教育程度（P = 0.011）、接触化学物质（P < 0.001）和工作部门（P < 0.001）有显著关联。功能性便秘的总患病率为9.7%，轮班工作的工人患病率高于仅上早班的工人（10%对6%；P = 0.02）。与功能性便秘相关的独立因素包括年龄（30至40岁：OR = 1.88；95%CI（1.20，3.03），≥41岁：OR = 1.91；95%CI（1.12，3.17））、吸烟（OR = 1.52；95%CI（1.20，1.93））和工作部门（喷漆部门：OR = 0.33；95%CI（0.12，0.87），组装部门：OR = 0.44；95%CI（0.18，1.10），冲压和平台部门：OR = 0.12；95%CI（0.05，0.37））。
职业条件可能会影响排便习惯。轮班工作、正式工作和吸烟可能会增加便秘风险。
