This study will involve kindergarten children (aged 1-6 years). The research takes place in six different phases: 1) development of the information system and data integration, 2) classification of target groups of kindergarten children according to nutritional status, 3) anthropometric monitoring of the development of kindergarten children, 4) establishment of an electronic register of allergies, 5) implementation of an information platform in kindergartens, and 6) assessment of the validity of platform. The research will include a minimum of 450 participants from Split, Osijek and Zagreb County. Based on the completed standardized questionnaires the target groups of kindergarten children will be classified according to their nutritional status:~children who have a developed food allergy~children at risk of developing mild, moderate or severe allergic reaction to food~children with an allergological indication~The children with allergological indication (c) will be sent for further specialist evaluation, diagonstics and nutritionist advice at CHS.~The investigators will monitor how many kindergarten children have developed food allergy, food intolerance and another allergy (eg. inhalation allergy). Children with another type of allergy will be the refference control.
By achieving effective cooperation between the Children's Hospital Srebrnjak (CHS), the Reference center for clinical allergology in children of the ministry of health, and IN2 Ltd., part of Constellation Software Inc., it is planned to develop an IT platform for the introduction of personalized balanced nutrition in kindergartens. The collected data which include the screening of the population, anthropometrical measurements, physical activity status, and medical examination, will be used to create a Registry of Allergies. Through the implementation of research activities, it is expected to develop an IT platform for personalized balanced nutrition of preschool children, which consists of a developed information system for continuous monitoring using a website and/or a mobile application.
