Estudio con el objetivo de validar una escala para evaluar la contaminación de alimentos en el hogar y, medir su validez y confiabilidad. Se encuestaron madres o cuidadoras con niños menores a 5 años, en San Juan de Lurigancho en Lima Perú. La escala fue previamente sometida a una calificación de jueces expertos. Se realizó el análisis de factores con componentes principales, la consistencia interna fue medida con Kuder–Richardson Formula 20 (KR-20) y la validez de la prueba con el coeficiente Kaiser-Meyer-Olkin (KMO) y el test de esfericidad de Barlet. La muestra tuvo 194 cuidadoras. Se definieron tres componentes (prácticas de limpieza, prácticas de almacenaje y contaminación del niño) con un total de 10 ítems. El estudio concluye que esta escala puede contribuir a la planificación de intervenciones en el aspecto de contaminación en el hogar y por lo tanto reducir episo...

Objectives: To validate a scale to assess contamination of food at home and measure the validity and reliability. Methods: mothers or caregivers with children under 5 years were surveyed in San Juan de Lurigancho in Lima Peru. The scale was previously subject to a rating of expert judges. Factor analysis with principal components was performed; the internal consistency was measured with Kuder-Richardson Formula 20 (KR-20) and the validity of the test with the coefficient Kaiser-Meyer-Olkin (KMO) and the sphericity test Barlet. Results: The sample was 194 caregivers. Three components (Practices cleaning, storage practices and pollution of the child) with a total of 10 items were identified. The item Cleaning Practices had a KR-20 = 0.722 storage practices and food contamination 0.518 and 0.5 respectively. The validity of the test was KMO = 0.549 and 591,678. Barlet test, df = 136, (p <0.0...

Objective: To compare the knowledge of mothers on food contamination in the home between the towns of Peru and Costa Rica. Methods: It was conducted in a rural area of Peru (San Pablo and Huascar) in San Juan de Lurigancho in Lima, and Costa Rica (San Vicente of Three Rivers). The questions were part of a scale that was validated on an expert opinion. It was developed to measure three components or domains.After validation,the instrument was applied in Costa Rica with a group of mothers or caregivers with children under five. The application was developed in Peru in a population with similar characteristics. Results:The sample consisted of 50 caregivers in Costa Rica and 194 in Peru. There is no significant difference in the domains of contamination utensils at home (p=O.750>0.05) and knowledge of child illness (p=0.060>0.05). Knowledge of agents of contamination was highly significant (...
