Gender differences
There is some discrepancy in the evidence with regard to the differential impacts of gender on obesity prevalence.

Systems-based approach
So far mass media campaigns seem to have a limited effectiveness in changing behavior that influences obesity. At the same time they can increase knowledge and awareness regarding physical activity and diet which might lead to changes in the long term. Campaigns might also be able to reduce the amount of time spent sitting or lying down and positively impact the intention to be active physically.
