Risk of occurrence of constipation-related internal haemorrhoids in officers and soldiers in high-altitude and cold regions:effects of low dietary fibre intake
Objective:To investigate the association between the risk of constipation-related internal haemorrhoids and low dietary fibre intake in officers and soldiers living in cold regions at high altitude.Methods:A questionnaire survey was conducted to investigate the incidence of constipation and internal haemorrhoids among officers and soldiers in high altitude and cold regions.Risk factors for constipation-associated internal hemorrhoids were analyzed,and the relationship between low dietary fibre intake,constipation,and internal hemorrhoids was assessed by correlation analysis.Results:Among 607 military personnel,75 cases(12.4%)of constipation and 89 cases(14.7%)of internal hemorrhoids were reported.Of the internal hemorrhoids,62 cases(69.7%)were constipation-related internal hemorrhoids,while 27 cases(20.3%)were internal hemorrhoids unrelated to constipation.The pain scores and healing time of constipation-associated internal hemorrhoids were significantly higher than for non-constipation-related internal haemorrhoids(P<0.01).Multivariate logistic regression analysis showed that low dietary fibre intake(OR value=161.987)was a high-risk factor for the occurrence of constipation-associated internal hemorrhoids.The results of the bivariate correlation analysis showed a significant negative correlation between low dietary fiber intake and internal hemorrhoids(r=-0.635).After adjusting for the effect of constipation,partial correlation analysis showed no significant association between low fibre intake and internal haemorrhoids(P>0.05).Conclusion:Low fibre intake is a high risk factor for the development of constipation-related internal haemorrhoids in officers and soldiers living at high altitude and in cold climates,which mainly increases the risk of internal haemorrhoids indirectly through the development of constipation.
