Ethics approval and consent to participate

: Approval of the study protocol was obtained from the Ethical Committee at the Public Health and Community Medicine Department at the Faculty of Medicine, Cairo University. However, the Committee does not provide us with a reference number for approval. Required permissions for conducting the study were obtained from the Chairman of the Pediatric Hospital and from the head of the Gastroenterology Unit. A verbal informed consent was obtained directly from the legal guardian of all participants before data collection and after explanation of the study objectives. The Ethical Committee approved verbal consents because this study was conducted in a tertiary hospital draining from poor socioeconomic levels and it was expected that a considerable percent of the mothers was not educated. All procedures for data collection were treated with confidentiality.
