The Statements The Evidence
5.1 Water Safety
5.1a. Garden ponds and domestic swimming pools pose a large threat to infants and children. Adequate fencing regulations and public education have reduced the risk in other countries. There is evidence from observational studies that pool access barriers in private homes can reduce the risk of child drownings by about 75% i,ii.

5.2 Sports Facilities and Environments
5.2a. Rule changes in contact sports resulting in less axial loading have been associated with reduced cervical spine injuries. The value of rule changes in other situations has not been demonstrated i,ii .
(Health Gain Notation - 2 "likely to be beneficial")
caveat: Following rule changes in American Football which banned tactics involving charging head first, related cervical quadriplegic injuries fell by 85%. There is uncertainty whether rule changes in rugby have, or can, reduce the incidence of spinal cord damage. Further epidemiological studies are required.

5.2c. More active encouragement in wearing horse-riding helmets will result in fewer head injuries. Lightweight multipurpose helmets could also be used by children and adolescents in many sports. There is observational evidence that helmets worn by horse riders result in less injuriesi,ii but a formal evaluation of this and other equestrian safety manoeuvres is required. There is also evidence that the introduction of mandatory use of helmets and face masks has reduced head and eye injuries in ice-hockey playersiii.

5.2d. Polycarbonate eye protectors reduce eye injuries in racket ball and squash. Polycarbonate provides much higher protection than other materials. Such eye protection is mandatory in the military and official championships in the United States i.

5.2f. A package of preventative measures substantially reduce leg injuries during soccer. There was a 75% reduction in injuries in soccer teams randomly allocated to an intervention which involved enhanced warming up, extended shin guards, and prophylactic ankle taping in players with previous sprains.i It is not clear which aspect of the intervention was the most effective and further research is required.

5.2g. Wrist protectors can prevent the vast majority of wrist fractures among in-line skaters and rollerskaters. In a case-controlled study in America the wearing of wrist guards was associated with a 90% reduction in injuries to the wrist i.
