Overview
Epidemiology and Demographics
In Western countries the prevalence of Helicobacter pylori infections roughly matches age (i.e., 20% at age 20, 30% at age 30, 80% at age 80 etc). Prevalence is higher in third world countries. Transmission is by food, contaminated groundwater, and through human saliva (such as from kissing or sharing food utensils.)
According to Mayo Clinic, however, there is no evidence that the infection can be transmitted by kissing:
"No evidence indicates that this bacterial infection is transmitted by sharing food or kissing." (http://www.mayoclinic.org/peptic-ulcers/qanda.html)
A minority of cases of Helicobacter infection will eventually lead to an ulcer and a larger proportion of people will get non-specific discomfort, abdominal pain or gastritis. The prevalence of infection is greater in developing countries and is influenced by socioeconomic conditions, ethnic background and age. In the Philippines, there is scarcity of published data regarding the epidemiology of this bacterium. Locally unpublished reports revealed a prevalence of 5.6% seropositivity rate in children and 60% among 136 adult Filipino patients with dyspepsia using the Clotest® (Cabahug et. al. 2003 and Caballero et al., 1997, unpublished data). A lower prevalence rate of 42% was reported by Daez et. al. in 2002 (unpublished data) among 375 patients undergoing endoscopy at the Philippine General Hospital utilizing the rapid urease test and histopathology.
Incidence
- The incidence/prevalence of [disease name] is approximately [number range] per 100,000 individuals worldwide.
- In [year], the incidence/prevalence of [disease name] was estimated to be [number range] cases per 100,000 individuals worldwide.
- The incidence and prevalence of H. pylori infection are generally higher among people born outside North America than among people born here. Within North America, the prevalence of the infection is higher in certain racial and ethnic groups, the socially disadvantaged, and people who have immigrated to North America
Prevalence
- The prevalence of peptic ulcer disease is approximately 23.1 per 100,000 individuals but higher in men 29.4 per 100,000 than women 14.9 per 100,000[1]
- The prevalence of [disease/malignancy] is estimated to be [number] cases annually.
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
- Patients of all age groups may develop [disease name].
- The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
- [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
- [Chronic disease name] is usually first diagnosed among [age group].
- [Acute disease name] commonly affects [age group].
Race
- Peptic ulcer disease usually affects individuals of the African Americans with a higher proportion of African ancestry race.Non-Hispanic whites individuals are less likely to develop the peptic ulcer disease.
Gender
- Peptic ulcer disease rates for male and female children are similar[2].
- Men are more commonly affected by peptic ulcer disease than women in adulhood[1].
The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
