Cycle use (DfT, 1996)
There is not necessarily a direct link between these relationships. However, there are good grounds for believing that there are indirect links.
Strong cycle helmet promotion campaigns (or helmet mandation) are known to reduce cycle use (BHRF, 1020). Where cycle use is low, the risk of injury when cycling is higher due to a reduction in the 'safety in numbers' effect (Jacobsen, 2003; Wardlaw, 2002). Where cycle use is reduced, societal activity levels also decline, leading to increased average weight and obesity.
