Prevalencia de la infección por Helicobacter pylori en población sana en la Comunidad de Madrid Prevalence of Helicobacter pylori infection in the healthy population of Madrid (Spain)
Abstract
Objetivo: conocer la prevalencia de la infección por Helicobacter pylori en población sana en la Comunidad de Madrid. Material y métodos: estudio transversal descriptivo en el que se realiza el diagnóstico de la infección por Helicobacter pylori mediante la prueba del test del aliento con 13C-urea. Resultados: se estudian un total de 618 sujetos. De estos, 481 son considerados evaluables con una prevalencia de infección por Helicobacter pylori del 60,3%. En esta cohorte el 36,4% eran varones y el 63,6% mujeres con una prevalencia del 60,6 y 60,1% respectivamente sin diferencias significativas. La mediana de edad de los pacientes evaluados fue de 37,5 años (rango 4-82) estableciéndose que existe una relación lineal con significación estadística entre la infección por Helicobacter pylori y la edad (χ² lineal = 33,31; p Objective: to determine the prevalence of Helicobacter pylori infection in the healthy population of Madrid Autonomous Community (AC). Material and methods: a descriptive, cross-sectional study where Helicobacter pylori infection is diagnosed by means of the 13C-urea breath test. Results: a total of 618 subjects were studied. Among these, 481 were considered evaluable with a prevalence of Helicobacter pylori infection of 60.3%. In this cohort 36.4% were men and 63.6% were women, with a prevalence of 60.6 and 60.1%, respectively, and no relevant differences between both subgroups. The median age of patients was 37.5 years (range 4-82), and a statistically significant linear relationship between Helicobacter pylori infection and age (linear χ² =33.31; p < 0.001) was established -chances of infection increase with age. Prevalence increases with age and peaks at 60 to 69 years (83.3% infected). For 169 subjects (35.1%) education level was unknown, and no relationship between this level and Helicobacter pylori infection was found. Conclusions: the study shows that the prevalence of Helicobacter pylori infection in the healthy population of Madrid AC is high (60.3%), progressively increases with age, and peaks in people in their sixties. The sample showed no differences regarding sex or education level.
