[Food and nutrition knowledge of students graduating from basic education in the metropolitan area of Santiago, Chile].
The aim of this study was to evaluate the degree of knowledge on food and nutrition in students graduating from Basic Education in the Metropolitan Area of Santiago, Chile. A random sample of 249 students of both sexes (1:1) from public and non-public schools (1:1) and from high, medium and low socioeconomic level (SEL), was selected. SEL was measured through the Graffar Modified Scale, and the degree of knowledge on food and nutrition was evaluated through a standardized test of 29 multiple choice items, based on the objectives of the curriculum program. The test was divided in two areas: Area 1, which contemplated Food and Requirements and Area 2, Food, Personal and Environmental Hygiene. Data were analyzed by chi-square procedure, comparing students who obtained sufficient knowledge (greater than or equal to 50% of correct answers) with those who obtained insufficient knowledge (less than 50% of correct answers). Results of the study indicated that 39.8% of students registered sufficient knowledge, 31.3% and 65.9% in Area 1 and 2, respectively. According to SEL, 62.1% and 12.3% of students from high and low SEL, respectively, registered sufficient knowledge (p less than 0.001), and the same effect was observed in Areas 1 and 2. In relation to sex, 46.3% of females and 33.3% of males registered sufficient knowledge (p less than 0.05), fact which was confirmed in both areas of the test. No significant differences were registered in the degree of knowledge on food and nutrition of students from public and non-public schools. It is therefore concluded that the degree of knowledge on food and nutrition in students graduating from Basic Education differs significantly according to SEL and, sex. This study represents a basic contribution to the better understanding of factors affecting the degree of knowledge on food and nutrition in students graduating from Basic Education in Santiago, Chile, and may serve as base-line for further studies on the subject.
