DAGIS – Increased Health and Wellbeing in Early Education and School Children
The DAGIS project focuses on socioeconomic differences in children’s energy balance-related behaviours (EBRB) and stress regulation and how they are influenced by factors in early education, at school and at home. A large cross-sectional survey of preschool children was conducted in 2015-2016 followed by a 5-month intervention to EBRBs and stress regulation in preschool children in 2017-2018. Participants will be followed up in 2023-2024.
DAGIS is a consortium study focusing on health and wellbeing in early education and school children in Finland. The DAGIS project is especially interested in following EBRBs (energy balance-related behaviours), including fruit and vegetable intake, intake of sugar-sweetened (everyday) foods and drinks, physical activity, sedentary behaviour, screen time, and stress regulation and investigating how they are associated with socioeconomic status. The DAGIS project has investigated the preschool as a setting for health promotion to improve EBRBs and decrease socioeconomic differences among children for these behaviours.
The DAGIS project started in 2014. A needs assessment, including a cross-sectional survey of over 800 children and parents across eight municipalities in Finland, was carried out in 2015-2016 (responsible researcher Eva Roos). The DAGIS survey study collected data on energy balance-related behaviours (EBRBs: sedentary and dietary behaviours, physical activity, sleep habits) and stress regulation in Finnish 3-6-year-old preschool children, alongside data on home and preschool environment. Survey findings were used to design an intervention program, which was carried out in 2017-2018 as a randomised controlled trial in preschools across two Finnish municipalities: Salo and Riihimäki (responsible researcher Carola Ray). The intervention aimed to improve children’s EBRBs and self-regulation skills and to decrease socioeconomic differences in EBRBs
Data collection for the DAGIS project continues in 2023. Participants in the DAGIS survey study in 2015-2016 will be followed up to investigate the relationship between circadian rhythms, eating, sleeping and adiposity among the now 11-14-year-old adolescents (responsible researcher Eva Roos). The relationship between early childhood diet and allergies and asthma will also be investigated in the same study.
Participants in the DAGIS preschool intervention in 2017-2018 will also be followed up to identify past and present environmental and individual factors linked to health behaviours, self-regulation and learning among schoolchildren (responsible researcher Carola Ray). The DAGIS Salo follow-up study will begin in autumn 2023 and the now 8-12-year-old schoolchildren in Salo municipality will be invited to participate in the study.
The DAGIS consortium continues to report findings and publish results via scientific articles. The consortium also includes research groups at University of Helsinki, led by Maijaliisa Erkkola and University of Eastern Finland, led by Nina Sajaniemi.
