There's a survey out this week because of Walk to School Week which has found that parents disproportionately fear their children being abducted or killed in a road accident over the more likely threat to their health from childhood obesity. (It was a YouGov of 1244 parents of primary school aged children.)
Parents were asked what they fear most for their children (from a given list) and 30% stated abduction or murder, with only 5% revealing a fear for their child's poor health in later life due to their child's current level of physical activity. The same survey found that 49% of parents under-estimated the amount of physical activity their children should get in a week.
The BBC are wondering what Mumsnetters think - are you worried about your child being knocked down on the way to school and does that fear make you more likely to drive to school or take kids by public transport than walk?
