The average age of the subjects was 49.9 ± 13.04 (SD) years, which concludes that most of the gastritis patients are at their productive ages. The results of this study are similar to a study conducted by Garg B, et al, which reported that the average age of gastritis patients was 47 years old and the study reported by Mustapha SK, et al with an average age of 47 years old [7, 8].
