Objective: Constipation is a common pediatric problem worldwide. This study aims to describe the clinical characteristics of constipation in Jordanian children according to their age groups. Methods: All patients suffering from constipation treated in our pediatric gastroenterology department between September 2009 and December 2012 inclusive. Hospital records were reviewed. Demographic data, clinical characteristics and final diagnosis were recorded. Data were analyzed according to the following age groups: infants, preschool age, school age and adolescents and gender. Results: During the study period, 137 patients identified. 11 patients excluded. The number (percentage) of patients according to age groups was: Infants 43 (34.1%), preschool children 55 years (43.7%), school children 25 years (19.8% ) and adolescents three (2.4%). Men represented 54.8%. There were no statistical differences between sexes in any age group. The most common symptom across all age groups was dry, hard stools. Infrequent defecations were noted in almost half of the patients. Fecal incontinence was more common among school-aged children than among preschool-aged children and adolescents. Abdominal pain was observed in almost 40% of our constipated children. The prevalence increases with age. Girls were affected more than boys. Fecal mass in the rectum was the most common physical finding. This affected boys more than girls. Functional constipation was the most common underlying cause. Conclusion: The clinical features of constipation in children vary by age group and gender. These differences should be taken into account when dealing with constipated children.Keywords: constipation, infants, preschool age, school age, adolescents.Clinical features of constipation in Jordanian children:Introduction:Constipation is.. .... middle of paper... ...Gastroenterology.2006; 130:1527-1537.19.
