A stAPP to a Healthier Lifestyle: a Randomized Controlled Trial

Recent scientific research has shown that prolonged sitting, also called sedentary behavior may have adverse effects on health. An increased negative association was found with cardio-metabolic risk factors, type 2 diabetes and premature mortality.

The occurrence of these adverse health effects even appears to be independently of the degree of physical activity. There is more and more evidence to interrupt prolonged sitting regularly.

Until today there is still no international scientific standard that specifies how often the sitting behavior should be interrupted. Moreover, it is also unclear how long the breaks should take to counter adverse health effects. Only a few studies examined the health effects after an intervention that aimed to reduce the sitting behavior.

Currently, there is a great need for interventions in which one is made aware of the problem of sedentarity, but by which, one is equally encouraged changing behavior in the short as well as long term. In the proposed project the investigators therefore contribute to a good method to fight sedentary behavior in an innovative way. The investigators will try to achieve that goal through the development and implementation of an application on the smartphone.

Recent figures show that it is impossible to ignore the existence of the smartphone with all its applications. In 2011 40.4% of the Flemish people owned a smartphone. In the same year 650 000 smartphones were sold in Belgium. In 2012, according to projections this number should be increased by 250% to 1.625 000.
