BACKGROUND & AIMS: Previous studies have indicated that, in addition to the types of food consumed, eating habits are also associated with the risk of esophageal diseases. Some studies have suggested a possible link between breakfast skipping and esophageal tumors as well as gastroesophageal reflux disease. However, it remains unclear whether breakfast skipping has a causal relationship with esophageal diseases. To address this issue, this study aimed to investigate the potential causal relationship between breakfast skipping and esophageal diseases using a two-sample mendelian randomization (MR) approach.
METHODS: We obtained data from genome-wide association studies (GWAS) involving 193,860 individuals from the UK Biobank on breakfast skipping. The summary statistics for the esophageal diseases were derived from the IEU open GWAS project. In this two-sample MR analysis, inverse variance weighted was used, supplemented with weighted median, simple mode and weighted mode methods.
RESULTS: The results revealed significant causal relationships between breakfast skipping and esophageal cancer (odds ratio (OR): 5.992, 95 % confidence interval (CI): 1.606-22.350, p = 0.008), Barrett's esophagus (OR: 4.041, 95 % CI: 1.837-8.889, p < 0.001), gastroesophageal reflux disease (OR: 2.463, 95 % CI: 1.995-3.041, p < 0.001), and esophageal varices (OR: 4.454, 95 % CI: 1.785-11.112, p = 0.001). All of the supplementary methods supported the findings.
CONCLUSION: Our research provides evidence for the association between breakfast skipping and esophageal diseases. Breakfast skipping could be a potential risk factor for esophageal cancer, Barrett's esophagus, gastroesophageal reflux disease and esophageal varices. For high-risk groups prone to these esophageal diseases, emphasizing the importance of regular breakfast and maintaining consistent dietary habits is crucial for esophageal health.
