The ads, which have been created by The Gate, will run in women's weeklies including Heat, Closer, OK and Hello! as well as in TV listing titles such as What's on TV and TV Choice.
The one-off campaign, which will run for four weeks, will target parents with children under 11 years old. It intends to raise awareness of the link between obesity and heat disease, cancer and type 2 diabetes and communicate to parents that their children must eat a healthy, well-balanced diet and be more active, to avoid developing these conditions.
The charity trio's press ads support the government's current campaign for Change4Life, which launched on 3 January, comprising TV, outdoor and press activity.
