Increased dependence on motorized transportation may contribute to obesity. Countries in rapid socioeconomic transitions, such as China, provide an opportunity to investigate such an association.
The aim of the study was to examine the hypotheses that increased dependence on motorized transportation is related to adiposity and that this effect will be more pronounced in adults with high SES or those who live in urban regions.
Data from the longitudinal China Health and Nutrition Survey conducted from 1997 to 2006 (n=3853, aged 18-55 years at baseline, 52% women, ~7.8 years' follow-up) were used to examine the association between motorized transportation (none, 1-5 years, >5 years) and changes in body weight and waist circumference (WC) by using multivariate regression. SES factors were obtained from questionnaires. Data were analyzed in 2010.
Use of motorized transportation for >5 years was related to ~1.2 kg greater weight gain (p=0.006) and ~1.0 cm larger WC gain (p=0.017) in men, when compared with the nonmotorized transportation group and adjusted for baseline age, anthropometry, dietary intake, and follow-up time. These changes were slightly more pronounced in men with higher income or from rural areas, but the difference was not significant. In women, the tendency to have motorized transportation with weight gain was less pronounced (+1.1 kg, p=0.008). Low education and high income were the most predominant factors. In 2006, motorized transportation was associated with a 1.3-fold higher OR for obesity (p(trend)=0.054) and abdominal obesity (p(trend)=0.047) in men, and a 2-fold higher OR of obesity in women (p(trend) <0.001).
Motorized transportation was related to an increase in adiposity in the Chinese population, particularly in men.
对机动交通工具的依赖增加可能导致肥胖。中国等处于快速社会经济转型期的国家为研究这种关联提供了机会。
本研究旨在检验以下假设：对机动交通工具的依赖增加与肥胖有关，且这种影响在社会经济地位较高的成年人或生活在城市地区的成年人中更为显著。
使用 1997 年至 2006 年进行的中国健康与营养调查（n=3853，基线时年龄为 18-55 岁，女性占 52%，随访时间约为 7.8 年）中的数据，采用多元回归分析来检验机动交通工具（无、1-5 年、>5 年）与体重和腰围（WC）变化之间的关联。社会经济地位因素从问卷调查中获得。数据分析于 2010 年进行。
与非机动交通工具组相比，男性使用机动交通工具>5 年与体重增加约 1.2kg（p=0.006）和 WC 增加约 1.0cm（p=0.017）相关，且校正了基线年龄、人体测量学、饮食摄入和随访时间。在收入较高或来自农村地区的男性中，这种变化更为显著，但差异无统计学意义。在女性中，体重增加与使用机动交通工具的趋势不太明显（增加 1.1kg，p=0.008）。受教育程度低和收入高是最主要的影响因素。2006 年，在男性中，与肥胖（p(trend)=0.054）和腹部肥胖（p(trend)=0.047）相关的 OR 值，使用机动交通工具的人群是不使用人群的 1.3 倍，而女性肥胖的 OR 值则为 2.0 倍（p(trend)<0.001）。
在中国人群中，机动交通工具与肥胖增加有关，尤其是在男性中。
