“…Despite the large number of publications in the field of early childhood health education, we were able to include few in the review due to the fact that many of them were cross-sectional studies of children's health knowledge, health status and healthy habits [62][63][64][65][66][67], and also because the majority of recent publications did not focus directly on children, but collected data on children's health behavior based on the perceptions of adults around them (parents, teachers, health professionals) [68][69][70][71][72][73]. Although some studies described interventions in institutional settings for children aged 3-6, they were not pedagogical in nature, but aimed to influence children's health behavior only through infrastructural developments (e.g., adding new play equipment to the playground environment) [74,75]. Thirdly, many studies took a health science approach, often focusing on public health measures (e.g., vaccination) [72,76,77] or on a specific group of diseases [78][79][80] or skills development (motor, cognitive skills) [81][82][83].…”
