Here’s yet another to lose weight. Heavier people are more likely to be killed or seriously injured in car accidents than lighter people.
That could mean car designers will have to build in new safety features to compensate for the extra hazards facing overweight passengers. In the US, car manufacturers have already had to redesign air bags so they inflate to lower pressures making them less of a danger to smaller women and children. But no one yet knows what it is that puts overweight passengers at extra risk.
A study carried out in Seattle, Washington, looked at more than 26,000 people who had been involved in car crashes, and found that heavier people were at far more risk. People weighing between 100 and 119 kilograms are almost two-and-a-half times as likely to die in a crash as people weighing less than 60 kilograms.
And importantly, the same trend held up when the researchers looked at body mass index(BMI)— a measure that takes height as well as weight into account. Someone 1.8 meters tall weighing 126 kilograms would have a BMI of 39, but so would a person 1.5 meters tall weighing 88 kilograms. People are said to be obese if their BMI is 30 or over.
The study found that people with a BMI of 35 to 39 are over twice as likely to die in a crash compared with people with BMIs of about 20. It’s not just total weight, but obesity that’s dangerous.
While they do not yet know why this is the case, the evidence is worth pursuing, says Charles Mock, a surgeon and epidemiologist at the Harborview Injury Prevention and Research Center in Seattle, who led the research team. He thinks one answer may be for safety authorities to use — heavier crash-test dummies when certifying cars are safe to drive.
Crash tests normally use dummies that represent standard-sized males weighing about 78 kilograms. Recently, smaller crash-test dummies have also been used to represent children inside crashing cars. But larger and heavier dummies aren’t used, the US National Highway Traffic Safety Administration in Washington, D.C. told New Scientist.
The reasons for the higher injury and death rates are far from clear. Mock speculates that car interiors might not be suitably designed for heavy people. Or obese people, with health problems such as high blood pressure or diabetes, could be finding it tougher to recover from injury.
When they redesigned air bags to hold less pressure, the American car manufactures______.
选项
A、found it hard to set standards without the definition of obesity
B、incidentally brought about extra risks to obese passengers
C、based their job on the in formation of car accidents
D、actually neglected smaller women and children
答案
B
解析
题干:当他们重新设计气囊来减少气压的时候,美国汽车厂商——。此题考点为细节信息定位。文章第二段第二句话提到美国汽车制造商不得不重新设计此囊,减少气囊的压力,从而降低娇小女性和儿童面临的危险。因而D项错误。最后一句话转折结构揭示这样的做法可能给超重乘客带来更多的危险,答案为B项。
