目的：对机动化交通方式的依赖可能导致全球肥胖流行。中国交通模式的转变为研究汽车拥有量与肥胖之间的关系提供了一个理想的机会。我们的目标是确定是否机动化的交通形式促进obesity.Research方法和程序：一个多阶段的随机整群抽样过程中，选择来自中国8个省的家庭。数据包括家庭车辆拥有量和个人人体测量和社会人口状况。采用1997年中国4741名20 ~ 55岁成年人的横断面资料，探讨了汽车拥有量与肥胖的关系。队列数据（1989年至1997年），从2485年的成年人年龄在20至45岁，1989年（59%的后续）被用来衡量车辆收购的影响，成为obesity.Results的几率：我们的主要成果措施是目前的肥胖状态和在8年内成为肥胖的几率。1997年，84%的成年人没有机动交通工具。然而，与没有机动车的人相比，拥有机动车的家庭中的男性和女性肥胖的几率高出80%（p < 0.05）。1989年至1997年，14%的家庭拥有了机动车。与那些拥有汽车的人相比，拥有汽车的人体重增加了1.8公斤（p < 0.05），肥胖的几率为2比1。
Objective: Dependence on motorized forms of transportation may contribute to the worldwide obesity epidemic. Shifts in transportation patterns occurring in China provide an ideal opportunity to study the association between vehicle ownership and obesity. Our objective was to determine whether motorized forms of transportation promote obesity.Research Methods and Procedures: A multistage random-cluster sampling process was used to select households from eight provinces in China. Data were included on household vehicle ownership and individual anthropometric and sociodemographic status. Cross-sectional data (1997) from 4741 Chinese adults aged 20 to 55 years were used to explore the association between vehicle ownership and obesity. Cohort data (1989 to 1997) from 2485 adults aged 20 to 45 years in 1989 (59% follow-up) were used to measure the impact of vehicle acquisition on the odds of becoming obese.Results: Our main outcome measure was current obesity status and the odds of becoming obese over an 8-year period. In 1997, 84% of adults did not own motorized transportation. However, the odds of being obese were 80% higher (p < 0.05) for men and women in households who owned a motorized vehicle compared with those who did not own a vehicle. Fourteen percent of households acquired a motorized vehicle between 1989 and 1997. Compared with those whose vehicle ownership did not change, men who acquired a vehicle experienced a 1.8-kg greater weight gain (p < 0.05) and had 2 to 1 odds of becoming obese.Discussion: Encouraging active forms of transportation may be one way to protect against obesity.
