We thank Dr Derakhahan and Professor McColl for their interest in our paper and for giving us the opportunity to present further data from our population-based study. We agree that information on the age-specific prevalence of hiatus hernia in males and females, which are still lacking, may be valuable in understanding the role of gender in Barrett’s oesophagus and oesophageal adenocarcinoma.

In our study population hiatus hernia was found in 444 out of 1033 individuals (43%, 95% confidence interval (CI), 40% to 46%).¹ The prevalence of hiatus hernia was 43% (227/528) in males and 43% (217/505) in females.

There was a significant relationship between hiatus hernia and age. The prevalence of hiatus hernia significantly increased from 32 to 41 years (34.3%, 36/105) to 42–51 (41.2%, 108/262), 52–61 (45.3%, 106/234) and 62–71 years (46.7%, 108/231, p = 0.03 vs 32–41 years).
