Abstract
in English, Spanish

Objective: To determine the prevalence of cow´s milk allergy and lactose intolerance in a sample of late adolescents.

Methods: Through a population-based study, data corresponding to students with aged 15 to 18 years were analyzed.

Results: A total of 1992 adolescents was analized. The prevalence of cow´s milk allergy was 1.4% (95% CI: 0.2% to 0.8%) and the prevalence of lactose intolerance was 0.5% (95% CI: 0.2% to 0.8%). Adolescents with cow´s milk allergy had fewer gastrointestinal symptoms (p = 0.036), but more skin (p < 0.001) and respiratory (p = 0.028) ailments than adolescents with lactose intolerance.

Conclusions: The manifestations associated with cow's milk consumption in late adolescents seem to correspond mainly to cow´s milk allergy than to lactose intolerance.

Objectivo: Determinar la prevalencia de alergia a la proteína de la leche de vaca e intolerancia a la lactosa en una muestra de adolescentes tardíos.

Métodos: Estudio transversal con base poblacional, en el que se analizaron los datos de pacientes adolescentes de 15 a 18 años.

Resultados: Se registraron 1992 estudiantes. La prevalencia de alergia a la proteína de la leche de vaca fue de 1.4% (IC95%: 0.9% a 2.0%) y de intolerancia a la lactosa de 0.5% (IC95%: 0.2% a 0.8%). Los adolescentes con alergia a la proteína de la leche de vaca tuvieron menos síntomas gastrointestinales (p = 0.036), pero más molestias cutáneas (p < 0.001) y respiratorias (p = 0.028) que los adolescentes con intolerancia a la lactosa.

Conclusiones: Las manifestaciones asociadas con el consumo de leche de vaca en adolescentes tardíos corresponden, principalmente, a la alergia de la proteína de la leche de vaca que a la intolerancia a la lactosa.
