Choosing an active way to get to work could make a big difference in how much weight creeps on in middle age, a large U.K. study suggests.
英国一家大型调查机构近日表示，选择一种积极的方式上班，也许对中年时期悄悄出现的发福有很大的影响。
Studying tens of thousands of commuters over age 40, researchers found that people who drove to work weighed more and had a higher percentage of body fat than those who got to work by walking, biking or public transportation.
在研究了成千上万名40多岁的乘客之后，研究人员发现，开车上班的人体重更重，体脂比也比那些步行、骑自行车或者使用公共交通系统上班的人高。
Those who commuted by bicycle were the leanest of all, but even taking the train was linked to lower body weight and body fat, the authors report in The Lancet Diabetes and Endocrinology.
作者在医学杂志《柳叶刀》的糖尿病和内分泌学上指出，那些骑自行车上班的人是所有人里最苗条的，但是即便乘火车，也会使得体重更轻，体脂更低。
"We know that exercise protects against obesity and chronic diseases. However, we all struggle to fit enough of it into our busy lives," said lead author Ellen Flint of the London School of Hygiene and Tropical Medicine.
伦敦卫生和热带医学学院首席作者Ellen Flint说道：“我们知道，锻炼可以预防肥胖和慢性疾病。然而，我们都在努力在匆忙的生活中给身体锻炼留下一席之地。”
"This study shows that people who manage to build physical activity into their daily commute have significantly lower body weight and healthier body composition than those who commute by car," Flint told Reuters Health by email.
Flint通过电子邮件告诉路透健康：“这项研究表明，比起开车的人，那些试图在日常交通中融入体力活动的人，拥有较显著的轻体重和更健康的身体构成。
In the U.S., about one third of adults are obese and no more than about 18 percent commute to work by walking or biking, according to the Centers for Disease Control and Prevention. Car travel was the most common method of commuting, with 64 percent of men and 61 percent of women reporting they drove for all or part of their commutes.
跟据疾控中心数据显示，在美国，大约有三分之一的成年人都肥胖，其中约18%的人选择步行或者骑自行车上班。开车是最常见的通勤方法，64%的男性和61%的女性表示，他们全部或者部分依靠私家车上下班。
Men and women who commuted to work by any means other than driving had lower body fat percentage and BMI compared to adults who commuted by car, researchers found.
研究人员发现，任何不开车上班的男性或者女性，体脂比和身高体重比都比开车上班的人低。
Even after accounting for a wide range of characteristics and lifestyle information about the participants, active commuting methods were linked to lower body weight and body fat.
即便在考虑到参与者的个性和生活方式信息之后，积极的通勤方式仍和低体重、低脂有关。
