The Prevalence Of Functional Gastrointestinal Disease In The Pediatric Gastrointestinal Clinic In Chongqing Area

Objective : To understand the epidemiological characteristics of functional gastrointestinal diseases in pediatric digestive clinic,and to strengthen the cognition of functional gastrointestinal diseases in children.Methods:Patients aged 0 to 18 years old in pediatric digestive clinic of Chongqing medical university affiliated children’s hospital between June 2016 to December 2019 were evaluated uterlizing functional gastrointestinal diseases ROME Ⅳ criteria.Results : A total of 11810 patients were enrolled in pediatric digestive clinic and 2788 were FGIDs patients(23.61%).The prevalence of FGIDs was 19.48%(1664/8541)in the neonate/toddlers group and 34.38%(1124/3269)in the children/adolescent group.The prevalence of FGIDs in children/adolescents group was significantly higher than that in neonate/toddlers group(χ~2=291.08,P < 0.01).The prevalence of FGIDs was higher in female than in male(P<0.01)in neonate/toddlers group(χ~2=24.19),children/adolescents group(χ~2=12.64)and the total population(χ~2=28.86).The most common type of FGIDs in neonate/toddlers was functional constipation(49.04%),followed by were infant dyschezia(22.96%),infant regurgitation(14.00%),functional diarrhea(10.76%),and infant colic(2.58%).Cyclic vomiting syndrome(0.48%)and rumination syndrome(0.18%)were rare.The most common FGIDs in children/adolescents were functional dyspepsia(58.98%),then were functional constipation(21.17%),irritable bowel syndrome(9.25%),functional nausea/vomiting(6.05%),cyclic vomiting syndrome(1.78%),and functional abdominal pain-NOS(1.51%).However,aerophagia(0.45%),ruminantion syndrome(0.09%),abdominal migraine(0.35%),and nonretentive fecal incontinence(0.35%)were rare.56(3.37%,56/1664)patients with neonate/toddlers FGIDs had an overlap between FGID diagnoses,mainly infant nausea(G1),infant abdominal colic(G4)and infant defecation difficulty(G7).78 patients(6.93%,78/1124)with children/adolescents FGIDs had an overlapping phenomenon,mainly were cyclic vomiting syndrome,functional nausea/vomiting,functional dyspepsia,abdominal migraine,and functional constipation.Conclusion : About 1/4 of the patients in pediatric gastroenterology clinics are FGIDs,which is more common in children/adolescents than that of neonate/toddlers.Some FGIDs are correlation with age and gender.There is overlap in the diagnosis FGIDs in children.Pediatricians should pay attention to the diagnosis and treatment of children’s FGIDs to avoid misdiagnosis,mistreatment and overtreatment.
