State a research question with regard to a public health issue and explain how and why 2.0 technologies could help to answer the question.

What will be an ideal response?

Ans: Public health issues do not concern individual health but the health of a population (however big or small). The issue stated should be suitable to be investigated with information and communication technologies. In particular through the specific social, participatory or interactive features of these technologies where people have access to and know how to use for that purpose. This would be an example of such a research question:”How effective is this mobile fitness app when it comes to weight loss, health and well-being among obese children (8-12yrs) as compared to children with normal weight using the same app?”
