Providing children with a healthy start to life: promoting physical activity and reducing sedentary behaviours during early childhood.

幼儿期（0-5岁）是养成健康行为并可能影响到以后生活的时期，是对身体活动和久坐行为产生积极影响的时期。然而，对3-5岁儿童的这些行为的研究才刚刚开始，对更小的儿童几乎不存在。该项目旨在通过一系列纵向研究，包括客观测量，了解这些行为的预测因素，并将从3个月大的时候开始。它将通过调查现有干预措施中行为改变的机制，研究促进幼儿期身体活动和减少久坐行为的战略，从而为有可能为儿童提供健康生活开端的新战略提供信息。

Early childhood (0-5 yrs), when health behaviours develop and may track into later life, represents promise as a time to positively impact physical activity and sedentary behaviour. Yet study of these behaviours in 3-5 yr olds is only emerging, and is almost non-existent in younger children. This project aims to understand predictors of these behaviours using a suite of longitudinal studies, including objective measures, and will commence as early as 3-mths of age. It will study strategies for promoting physical activity and reducing sedentary behaviours during early childhood, by investigating mechanisms of behaviour change in existing interventions to inform new strategies with potential to provide children with a healthy start to life.
