中国人民大学经济学院陆方文研究小组宣布他们分析了中国北京居民购车后的体力活动和体重变化。研究结果表明，在一个快速增长的国际化城市中，拥有汽车会导致长期的体力活动减少和体重增加。发展中国家和中等收入国家汽车使用和拥有量的持续增加可能会对身体健康和肥胖产生不利影响。该研究成果发表于国际一流学术期刊《英国医学杂志》上。（科学网）

The Lu Fangwen team, from the school of economics at Renmin University of China, announced that they had analysed changes in physical activity and body weight among residents of Beijing, China, after buying a car. The results suggest that owning a car in a rapidly growing international city can lead to long-term physical activity loss and weight gain. Continued increases in car use and ownership in developing and middle-income countries could have adverse effects on health and obesity. The findings were published in the British Medical Journal.(sciencenet.cn)
