425 million people were living with diabetes in 2017. Most of these cases are type 2 diabetes. Another 352 million people were estimated to be at high risk of developing type 2 diabetes in 2017.
While there are a number of factors that influence the development of type 2 diabetes, it is evident that the most influential are lifestyle behaviours commonly associated with urbanization. These include consumption of unhealthy foods and inactive lifestyles with sedentary behaviour. Randomised controlled trials from different parts of the world, including Finland, USA, China and India, have established the that lifestyle modification with physical activity and/or healthy diet can delay or prevent the onset of type 2 diabetes.
Modern lifestyles are characterised by physical inactivity and long sedentary periods. Community-based interventions can reach individuals and families through campaigns, education, social marketing and encourage physical activity both inside and outside school and the workplace. IDF recommends physical activity at least between three to five days a week, for a minimum of 30-45 minutes.
Taking a life course perspective is essential for preventing type 2 diabetes and its complications. Early in life, when eating and physical activity habits are established and when the long-term regulation of energy balance may be programmed, there is an especially critical window to prevent the development of overweight and reduce the risk of type 2 diabetes. Healthy lifestyles can improve health outcomes at later stages of life as well.
Population based interventions and policies allow healthy choices through policies in trade, agriculture, transport and urban planning to become more accessible and easy. Healthy choices can be promoted in specific settings (school, workplace and home) and contribute to better health for everyone. They include exercising regularly and eating wisely which will help to maintain normal levels of blood glucose, blood pressure and lipids.
