機車安全帽型式及非標準使用對頭部傷害之影響



共收集 240 位因機車就醫診斷有頭部傷害的個案組和 280 位無頭部傷 害的對照組。條件式邏輯斯迴歸分析分成，模式一，與佩戴全頂連下 顎型騎士相比，半頂型與全頂不連下顎型發生頭部傷害的勝算比分別 是 2.6 、 2.9 倍，達統計顯著。將機車維修費作為撞擊嚴重度 納入分 析為模式二，佩戴半頂型與全頂不連下顎型的騎士發生頭部傷害的勝 算比是全頂連下顎型騎士的 2.3 (95% 信賴區間 0.8-6.3) 、 2.6 倍 (95

% 信賴區間 1.0-6.6) 。安全帽對於機車騎士頭部傷害有保護作用，但 是依不同型式而異。與全頂連下顎型安全帽相比，全頂不連下顎型以 及半頂型會增加騎士發生頭部傷害的危險。控制撞擊嚴重度後，全頂 不連下顎型發生頭部傷害的勝算比則未達統計顯著。騎士對機車的熟 晰度、冒險性行為、及碰撞機轉會干擾非標準使用對於頭部傷害的影 響，本研究目前無法對非標準使用為頭部傷害的危險因子下結論。

Impact of Helmet Type and Non-Standard Use on Head Injury in Motorcycle Riders



The introduction of the Taiwan Mandatory Helmet Use Law in 1997 led to a drama tic decrease in motorcycle-related fatalities and head injuries among fatally and non fatally injured riders. A case-control study was conducted to understand the effect o f non-standard helmet use and helmet types on head injury. A total of motorcycle-r elated injured patients occurred over 8-month period from 1st, January to 31st, Aug ust 2006 in emergency room of China medical university hospital, 240 subjects wit h head injury were defined as cases and 283 without head injury as controls. The re sults of conditional logistic regression was divided into two models. As the results of model 1, compared with full-face helmet, full helmet (OR=2.6, 95% Confidence Interval (CI): 1.1-6.3) and partial-coverage helmet (OR=2.9, 95% CI: 1.2-6.6) incre ased the odds for a greater level of head injury. When crash severity was controlled in model 2, ORs for full helmet and partial –coverage helmet became 2.3 (95% CI:

0.8-6.3) and 2.6 (95% CI: 1.0-6.6), respectively. Non-standard use of helmet didn’t

show significantly increased risk of head injury. The risk of head injury among mot

orcycle riders was significantly increased by wearing a partial coverage helmet whe

n compared with full-face helmet, but not by full helmet. Unexpectedly, we can’t c

onclude non-standard helmet use contribute the risk of head injury among motorcyc

lists.
