Levels of physical activity (PA) and physical fitness in children are low and declining, both globally and in Sweden. Preschools are important settings with the potential to influence the majority (>93%) of Swedish children's PA behaviors in early stage of life (<5 years). Preschool policy is an organizational level factor associated with children's PA but the casual link remains unclear. A cluster randomized controlled trial will be conducted to explore the feasibility and effectiveness of implementing a policy package for children's PA levels and other relevant health indicators.
The overarching aim of the proposed project is to examine the effects of implementing physical activity (PA) policies in preschools on PA and indicators of health in young children. The proposed project is a unique collaboration between the applicants and Stockholm stad which will result in PA policies, that will be implemented in all 658 public preschools within the Stockholm region, having the possibility to affect more than 38 000 children.
The current study is designed as a cluster randomized controlled trial with 2 conditions (intervention vs. control) and preschools serving as the unit of randomization. Measures of primary and secondary outcomes will be obtained at baseline and at 6-months on an individual level.
This study will provide robust evidence of the effect of structural changes, at the organizational level of preschools, on children's PA and indicators of health. Notably, such robust evidence is urgently warranted as Swedish preschool children's PA levels are low which will have long-lasting effects on their lives. Finally, as the intervention has been developed in co-creation with Stockholm stad it has the possibility to, if proven effective, be implemented rapidly within preschools.

Musculoskeletal fitness, in terms of handgrip strength ,will be measured by an analogue dynamometer (TKK 5825, Grip-A, Takei, Tokyo, Japan).
| Change from baseline to 6 months follow-up in musculoskeletal fitness (handgrip strength) |
| Change in anthropometry (weight in kg) of children | Weight will be measured by validated scales (calibrated scale: VB2-200-EC, Vetek AB, Väddö, Sweden) | Change from baseline to 6 months follow-up in anthropometry |
| Change in anthropometry (height in cm) of children | Height will be measured by validated scales (portable stadiometer: Seca 213, Seca, Chino, CA, USA) | Change from baseline to 6 months follow-up in anthropometry |
| Change in anthropometry (waist circumference in cm) of children | Waist circumference will be measured at the level of the navel directly on the skin | Change from baseline to 6 months follow-up in anthropometry |
| Change in anthropometry (BMI) of children | Weight and height will be combined to report BMI in kg/m^2 | Change from baseline to 6 months follow-up in anthropometry |
| Change in psychosocial functioning of children | Psychosocial functioning of children will be assessed by a parental proxy report of the Strength and Difficulty Questionnaire. Total difficulties score is generated by summing scores from all the scales except the prosocial scale and ranges from 0 to 40, higher score means worse outcome. | Change from baseline to 6 months follow-up in psychosocial functioning |
| Change in sleep of children | Sleep will be measured objectively by the GT3X+ accelerometer combined with a sleep time diary documented by parents during the days when the child is wearing the accelerometer. In addition, parents will answer questions about children's sleep duration and quality in the last 6 months in the sleep questionnaire. These sleep questions are adapted from the validated Ages and Stages Questionnaire. The sleep quality score ranges from 0-12 and higher score means better outcome. | Change from baseline to 6 months follow-up in sleep |

| Change in children's physical activity opportunities outside preschool time (process outcome) | Children's PA opportunities in terms of active transport and participation in organized sports will be assessed via a questionnaire (daily during the period that children are wearing the accelerometers) where parents answer time, duration and type of organized sports and mode of transportation to and from preschool. In addition, several parental practices (outdoor time during the weekend, parental perception of physical activity, parental physical activity, and active play with parents) which could potentially influence children daily physical activity levels will also be assessed by questionnaire. | Change from baseline to 6 months follow-up in children's physical activity opportunities outside preschool time |
