This study was designed as a retrospective cross-sectional survey included all consecutive gastrointestinal (GI) patients admitted over one year period in a random selected hospital group located in Tehran metropolitan in 2006. Residence, age, sex and type of GI disorders were analyzed respectively using quantile regression.

RESULTS

A total of 6405 patients with GI disorders were included in the study, There were 3633 men (56.7%) and 2772 women (43.3%). Type of diseases was a significance predictor for length of staying at hospital in quantile regression analysis. Age was significant only in second quartile and sex was not assessed as a predictor at all.

CONCLUSION
