title: Physical activity in children: prevention of obesity and type 2 diabetes.
abstract: There is strong evidence that increased physical activity is beneficial for blood glucose homeostasis and the prevention of obesity and type 2 diabetes mellitus. This chapter takes a life course approach with an emphasis on the intrauterine and childhood stages of life. Firstly, growth and development at critical periods with a focus on skeletal muscle and adipose tissue; then, obesity and type 2 diabetes mellitus are considered in relation to physical activity and sedentary behaviour. The importance of the development of fundamental movement skills in early childhood for both physical fitness and also growth and development is emphasised. Physical activity guidelines in westernised countries are examined for commonalities. Finally, the effective translation of the evidence base for the benefits of physical activity into randomised controlled trials and then into real-world public health services that are sustainable is addressed with a case study from New Zealand of Project Energize--a through-school physical activity and nutrition intervention. Physical activity, alongside a 'healthy diet' is arguably the best preventive measure and treatment for both obesity and type 2 diabetes. It is an essential and normal activity of daily life, and all aspects of the life course and the environment should support physical activity.
