Abstract

Background

The aim of our study was to identify potential risk factors for anal fistula in order to improve prevention and treatment of anal fistula.

Methods

A retrospective case–control study for anal fistula was conducted at our unit. Logistic regression analyses were carried out to identify associated risk factors for anal fistula.

Results

The final model obtained by the stepwise forward logistic regression analysis method identified the following items as independent risk factors: body mass index of >25.0 kg/m2, high daily salt intake, history of diabetes, hyperlipidemia, dermatosis, anorectal surgery, history of smoking and alcohol intake, sedentary lifestyle, excessive intake of spicy/greasy food, very infrequent participation in sports and prolonged sitting on the toilet for defecation.

Conclusions

Our results indicate that lifestyle factors and certain medical conditions increase an individual’s risk of developing anal fistula.
