The after-school period: A critical window for children's health behaviours

放学后的时间对儿童的体育活动和久坐行为很重要。这个博士学位的出版将建立在前两年的研究。迄今为止的进展包括界定放学后的时期，并审查随着时间的推移，这一时期对日常行为的影响和贡献。本论文将探讨课后行为模式的变化，确定评估这些行为相关性的调查项目的可靠性，并研究相关性。

The after-school period is important for children’s physical activity and sedentary behaviours. This PhD by publication will build on the first two years of study. Progress-to-date includes defining the after-school period and examining the prevalence and contribution the period makes to daily behaviours over time. This thesis will now examine changes in patterns of after-school behaviours, determine the reliability of survey items assessing correlates of these behaviours and examine correlates.
