HELMET WARS

[Better get your waders on. Make that a rubber suit.]

 

 

THE BRITISH HELMET CURMUDGEONS: CYCLEHELMETS.ORG The threat of mandatory helmet laws for adults in England has spawned the helmet skeptics. An impressive list of articles presented and/or skewered.

A CASE-CONTROL STUDY OF THE EFFECTIVENESS OF BICYCLE HELMETS Abstract of the widely-cited 1989 article by Thompson, Rivara and Thompson from the New England Journal of Medicine. Even if it's good data (which is highly debatable) does data concerning child bicyclists transfer to adults?

 

EFFECTIVENESS OF BICYCLE SAFETY HELMETS IN PREVENTING HEAD INJURIES Thompson, Rivara and Thompson, JAMA, 1996 (Abstract on JAMA site).

 

DAMAGE TO BICYCLE HELMETS INVOLVED WITH CRASHES Abstract of 1997 study by the Thompson-Rivara Seattle crew, shows that the vast majority of helmets that were worn by ER patients presenting with "head injuries" showed no damage at all or very little damage. Accident Analysis and Prevention, September 1997.

EFFECTS OF BICYCLE HELMET LAWS ON CHILDREN'S INJURIES Link to 2013 paper by Chatterji and Markowitz, National Bureau of Economic Research. The researchers find that reductions in children's injuries in places with mandatory helmet laws may be due to the decrease in cycling caused by the laws themselves.

TRENDS IN SERIOUS HEAD INJURIES AMONG CYCLISTS IN ENGLAND Interesting data from the 1990s showing decreasing head injury rate among wrecked riders could easily be explained by other factors besides helmets.

 

A DECREASE IN BICYCLE-RELATED HEAD INJURIES IN HELMET WEARING AGES IN SWEDEN (Abstract) Authors of 2007 article would like to ascribe a decrease in head injuries among Swedish children to increased helmet use; the fact that head injuries increased among adults during the same period won't stop them from doing just that. See this 2005 article which showed helmet use among all Swedes was increasing.
