Ingesta alimentaria en escolares chilenos de procedencia indígena y no indígena de diferente vulnerabilidad social / Food intake in indigenous and non-indigenous Chilean schoolchildren of different social vulnerability

ABSTRACT

The study was based on a cross-sectional design of children from six to nine year olds. Indigenous children were those whose parents had all surnames of this ethnic origin. Non-indigenous children were those with Hispanic surnames. Participants belonged to one of the three social vulnerability groups high vulnerability (extreme poverty) living in rural communities in a southern region of the country (n = 184); medium vulnerability living in urbanized settings in the same region (n = 248); low vulnerability living in Santiago of Chile (n = 336). Food intake was estimated using a 24-hours recall questionnaire. Total energy intake was similar in the two ethnic groups in all vulnerabilities. It was observed that energy and macronutrient intake increased with the improvement of the social vulnerability High 1679 kcal. with a standard deviation (SD) of 461, Medium 1878 (SD 484), Low 1894 (SD 495). Children in the high social vulnerability group had a total energy intake below the WHO/FAO recommendations. Consumption of milk, meat, vegetables and fruits was insufficient in all social vulnerability levels but it was closer to the recommendation in the low vulnerability group. Bread accounted for almost 50 per cent of the total energy intake in the high and medium vulnerability groups. It is concluded that differences in the access to an adequate feeding are related to social vulnerability and not ethnicity.
