Objective:To study the epidemiology of Helicobacter pylori(H.pylori) infection according to age group.Methods:H.pylori infection data among 1 965 consecutive patients referred to the Endoscopy Unit collected at Sungai Petani Hospital for oesophagogastro-duodenoscopy(OGD). The patients were divided into 9 age groups(10-19,20-29,30-39,40-49,50-59,60-69,70-79, 80-89 and 90-99 years).In addition these groups were further divided into three minor group namely young adults(10-39),older adults(40-69) and geriatric groups(70-99).Results:Overall prevalence of infection of H.pylori was analyzed and found that the prevalence increase with age (P<0.05).When the patients divided by ethnic and gender group with age,prevalence rate among young adults and older adults significantly higher(P<0.05) compared to geriatric groups across all races and gender(P<0.05).Furthermore,significantly higher number of males were infected compared to female(P<0.05) but such trend was only observed among older adult groups.In addition,there is a significant differences in H.pylori infection prevalence rates among ethnic groups(highest in Indians adults,followed Chinese and low in Malays,P<0.05).Conclusions: The overall prevalence of H.pylori did increase with age group across ethnicity and gender,in Northern Peninsular Malaysia.

Results: Overall prevalence of infection of H. pylori was analyzed and found that the prevalence increase with age (P <0.05) .When the patients divided by ethnic and gender group with age, prevalence rate among young adults and older adults significantly higher (P <0.05) compared to geriatric groups across all races and gender (P <0.05) .Furthermore, significantly higher number of males were infected compared to female (P <0.05) but such trend was only seen among older adult gr There was a significant difference in H. pylori infection prevalence rates among ethnic groups (highest in Indians adults, followed Chinese and low in Malays, P <0.05) .Conclusions: The overall prevalence of H. pylori did increase with age group across ethnicity and gender, in Northern Peninsular Malaysia.
