Catálogo fotográfico como herramienta para la estimación de la ingesta alimentaria en niños y adultos

Abstract

Introduction: Research collecting population-based food consumption data requires tools for estimating portions accurately to minimize errors. Nowadays, such tools are unavailable in Ecuador. This thesis aims to develop a photography manual as a tool for estimating dietary intake among children and adults. Materials and Methods: Eighty-five foods/recipes highly consumed in Cuenca-Ecuador were selected. Foods were selected according to previous research conducted by the Group Alimentació Nutrición y Salud-Universidad de Cuenca and by means of in depth interviews with housewives, and school food-kiosks/restaurants staff. The weight and volume of at least 20 portions served for children and adults was measured for each food item. For each food, the mean portion size was calculated seven portions. Each portion size was then weighted by means of a digital scale or measured using test tubes. Finally, a picture was taken to build the photography manual. Result: The proposed tool comprises 85 foods, includes 381 sheets with 1 photography each one, 227 photography for adults and 154 photography for children. The manual is divided into two sections the first one for 6 to 12 years old children and the second one for adults older than 18 years. Conclusion: The photography manual of Food Portions has been designed as a useful tool for food consumption evaluation among children and adults. The manual must be validated to verify its reliability.
