Abstract (English):	Background: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (EP-BLEE) are present in the feces of individuals in the community. In Peru, self-medication, type of diet and sanitary conditions could be associated with this colonization. Objective: to determine the frequency of rectal colonization by EP-BLEE in outpatients of the "Hospital Regional Lambayeque", as well as the factors associated with it, during the months of July 2018 to February 2019. Material and methods: 331 participating patients were interviewed, and three serial samples of freshly emitted stool were obtained from them. The samples were cultured on McConkey agar. EP-BLEE were confirmed with the combined disc test (American method). Results: 85.8% of patients were colonized by EP-BLEE, and Escherichia coli was the most frequent isolate (87.7%). Bivariate analysis associated the consumption of pork (RP=1.15, 95% CI: 1.07 - 1.24), goat (RP=1.18, 95% CI: 1.10 - 1.25) and frequent consumption of salads (RP=1.15, 95% CI: 1.05 - 1.28) with a higher probability of being a rectal carrier of EP-BLEE. Self-medication presented values close to the limit of validity (p=0.051, RP 1.12, 95% CI 0.98 - 1.26). Conclusions: Consuming pork, goat meat and salads increase the probability of being a carrier of EP-BLEE, while self-medication could be associated, so further research is needed, since the reasons for this finding are unknown.

Abstract (Spanish):	Introducción: Las Enterobacteriaceae productoras de betalactamasas de espectro extendido están presentes en las heces de los individuos de la comunidad. En Perú, la automedicación, el tipo de alimentación, condiciones sanitarias podrían asociarse a esta colonización. Objetivo: determinar la frecuencia de colonización rectal por EP-BLEE en pacientes de consulta externa del Hospital Regional Lambayeque, así como los factores asociados a la misma, durante los meses de julio 2018 a febrero 2019. Material y métodos: 331 pacientes participantes fueron entrevistados, de los cuales se obtuvieron tres muestras seriadas de heces recién emitidas. Las muestras fueron cultivadas en agar McConkey. Las EPBLEE se confirmaron con la prueba de disco combinado (método americano). Resultados: el 85,8 % de los pacientes estuvieron colonizados por EP-BLEE, siendo Escherichia coli el aislamiento más frecuente (87,7 %). El análisis bivariado asoció el consumo de carne de cerdo (RP=1,15 IC 95%: 1,07 - 1,24), caprino (RP=1,18, IC 95%: 1,10 - 1,25) y el consumo de ensaladas frecuentemente (RP=1,15, IC 95 %: 1,05 - 1,28) con una mayor probabilidad de ser portador rectal de EP-BLEE. La automedicación presentó valores cercanos al límite de validez (p=0,051, RP 1,12, IC 95% 0,98 - 1,26). Conclusiones: Consumir carne de cerdo, caprino y ensaladas aumentan la probabilidad de ser portador de EP-BLEE, mientras que la automedicación podría estar asociada, por lo que es necesario seguir investigando, ya que se desconocen las razones de este hallazgo en pacientes de la comunidad.
