The Relationship Between Prematurity, Method of Delivery, and Functional Gastrointestinal Disorders in Children.

OBJECTIVE

The pathogenesis of functional gastrointestinal disorders (FGIDs) remains unknown. Early life events including method of delivery and length of gestation may be risk factors for FGIDs. Data from studies on early life events and the development of FGIDs are scarce and contradictory.

OBJECTIVE

The aim of the study was to assess the association between mode of delivery, length of gestation, and FGIDs in children. We hypothesized that delivery via Cesarean section and prematurity would be associated with an increased prevalence of FGIDs.

METHODS

Questionnaires were mailed to families from 3 cities in Colombia. Parents provided information on mode of delivery, demographics, and medical history. School children completed the Spanish version of the Questionnaire of Pediatric Gastrointestinal Symptoms Rome IV. Categorical data were analyzed using Fisher exact tests. Calculation of odds ratio with 95% confidence interval was performed.

RESULTS

A total of 1497 children (535 preadolescents 10-12 years, 962 adolescents 13-18 years) participated. For participants born via Cesarean delivery, there was no significant increase in prevalence of any of the Rome IV FGIDs compared with vaginal delivery. There was a significant association between prematurity and FGIDs for those born between 28 and 32 weeks (confidence interval 0.99-3.37; P = 0.03). In this group, functional nausea was the only category of FGID to reach significance (0.16-112.23) (P = 0.02). However, statistical significance was lost when gestational ages were grouped together with multivariate analysis.

CONCLUSIONS

Our findings provide evidence that Cesarean delivery and prematurity are not risk factors for the development of FGIDs. Future studies are indicated to further evaluate the relationship between early life events and FGIDs.
