Background
The reflux of noxious contents of the stomach may cause oesophageal and extra-oesophageal complications either by direct contact of aspirated gastric refluxate with the upper airway or by a vago-vagal reflex. This study aimed to determine the prevalence of gastroesophageal disease (GERD) and extraesophageal manifestations among undergraduate students in a tertiary institution in Nigeria.
Methods
This is a cross-sectional study involving undergraduate students in a private University in Nigeria. Study proforma had three parts. Part A consisted of self-administered questionnaire designed to obtain students biodata. Part B consisted of standard Carlsson-Dent questionnaire. A score of 4 and above on Carlsson- Dent questionnaire was considered diagnostic of gastroesophageal reflux symptoms (GERD). Thereafter those who had GERD were further questioned and examined for extra-oesophageal symptoms of GERD.
Results
The total number of the study participants was 647, out of which 212 (32.8%) had GERD. One hundred and forty-four (67.9%) and 86 (32.1%) females and male had GERD respectively (p = 0.13).
The extraesophageal symptoms found in those with GERD were, dysphagia, coated tongue, nocturnal cough, xerostomia, lump in the throat, asthma-like symptoms, recurrent sore throat, frequent throat clearing, halithosis and dental erosion among others.
Conclusion
GERD is common among this study population, with a prevalence rate of 32.8%. Only age showed significant predictor for GERD. Varying extra-oesophageal manifestations were found in those with GERD.
