Its aim was to examine if mixed breastfeeding (MBF) and artificial feeding (LA) are risk factors for the development of Asthma in children between 2 and 5 years old, treated at Pediatric outpatient clinic of EsSalud Chocope Hospital, 2014. This study was embedded in a population-based retrospective case-control study of 225 children 2 to 5 years (75 asthmatic cases and 150 controls without asthma). The incidence of asthma was 9.9%; in cases males predominated 50.22%, in controls 50.67% were women. 60% of cases had 3-4 years old, and there were 52.67% children between 2-3 years in controls. 52% of cases were exclusive breastfed (EBF), 40% received mixed breastfed (MBF) and 8% were never breastfed (ABF); in controls 70.67% were exclusive breastfed. Children with MBF had a higher risk of developing asthma than those with EBF P = 0.0058, OR = 2.47 95% CI (1,33- 4,57); in ABF there were no statistically differences P = 0.6562, OR = 1.48 95 % CI ( 0,51- 4,38). Additional pathology in cases were found: 28% allergic rhinitis, atopic dermatitis 18.67% and 12% allergic rhinitis and atopic dermatitis. Similar behavior was observed in controls. We conclude that the EBF is a protective factor and MBF is a risk factor in the development of asthma in children between 2 and 5 yearsEl efecto protector de la lactancia materna exclusiva (LME) en el desarrollo de enfermedades alérgicas en lactantes y niños es controversial y considerando la alta prevalencia de Asma Bronquial en niños, se planteó evaluar si la lactancia mixta (LM) y la lactancia artificial (LA) son factores de riesgo para el desarrollo de Asma Bronquial en niños de 2 a 5 años de edad, atendidos en Consultorio Externo de Pediatría del Hospital II EsSalud Chocope, 2014. El estudio de Casos y controles en 6 meses, evaluó 225 niños de 2 a 5 años, (75 casos asmáticos y 150 controles sin asma). La incidencia de asma fue 9.9%; en los casos predominaron los varones 50.22%, en controles las mujeres 50.67%. El 60% de casos tuvo 3 a 4 años de edad, en controles 52.67% entre 2 a 3 años. El 52% de los casos tuvo LME, 40% LM y 8% LA; en los controles el 70.67% recibió LME. Los niños con LM tuvieron mayor riesgo de desarrollar asma que los que tuvieron LME P= 0,0058, OR = 2,47 IC 95% (1,33- 4,57); en la LA no se encontró diferencias estadísticas significativas P=0,6562, OR=1,48 CI 95% (0,51- 4,38). Las patología adicionales encontradas en los casos fueron: rinitis alérgica 28%, dermatitis atópica 18.67% y rinitis alérgica más dermatitis atópica 12%. Similar comportamiento se observó en los controles. Se concluye que la LME un factor protector y LM es un factor de riesgo para el desarrollo de asma bronquial en niños entre 2 a 5 añosspainfo:eu-repo/semantics/openAccessLactancia materna y asmaFactor de riesgoAsma bronquialinfo:eu-repo/semantics/bachelorThesis
