ABSTRACT
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 chi2 =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.

Objetivo: conocer la prevalencia de la infección por Helicobacterpylori en población sana en la Comunidad de Madrid.Material y métodos: estudio transversal descriptivo en el quese realiza el diagnóstico de la infección por Helicobacter pylorimediante 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 infecciónpor Helicobacter pylori del 60,3%. En esta cohorte el36,4% eran varones y el 63,6% mujeres con una prevalencia del60,6 y 60,1% respectivamente sin diferencias significativas. Lamediana de edad de los pacientes evaluados fue de 37,5 años(rango 4-82) estableciéndose que existe una relación lineal consignificación estadística entre la infección por Helicobacter pyloriy la edad (X2 lineal = 33,31; p < 0,001): a mayor edad mayorprobabilidad de infección. La prevalencia aumenta con la edadsiendo máxima entre los 60 y 69 años (83,3% infectados). En169 sujetos (35,1%) se conoce el nivel de estudios sin que existarelación entre este y la infección por Helicobacter pylori.Conclusión: el estudio muestra que la prevalencia de la infecciónpor Helicobacter pylori en población sana en Madrid es elevada(60,3%), y aumenta progresivamente a lo largo de la vida paraalcanzar un pico máximo en la 6ª década. No se encuentran diferenciasen la muestra en función del sexo ni del nivel de estudios
