Although rapid urbanization is often considered as one of the most important drivers for changing dietary patterns, little attention has been paid to rural areas despite the profound transformation they have undergone. Using longitudinal data from the China Health and Nutrition Survey (CHNS) for the period from 2004 to 2011, this study seeks to better understand the relationship between the urbanization of rural areas and dietary transition, with the focus on nutrition intake and dietary quality. Our results suggest that with increasing urbanization, rural residents tend to have on average lower calorie intakes but higher dietary quality. Specifically, increasing urbanization consistently reduces carbohydrate consumption and reduces fat consumption after a turning point; protein consumption first decreases and then increases after the turning point with increasing urbanization. Urbanization shows a significant and positive effect on the Healthy Eating Index (HEI). In addition to sociodemographic changes, we find that changing consumer preferences and knowledge serve as important determinants in explaining the dietary transition in rural China from 2004 to 2011. In our study, urbanization appears to positively affect rural residents' healthy food preferences and dietary knowledge. This study is a first attempt for better understanding the nutrition transition resulting from accelerating urbanization in rural China; several limitations and areas for future research have been highlighted.
虽然快速的城市化通常被认为是改变饮食模式的最重要驱动因素之一,但农村地区却很少受到关注,尽管它们已经经历了深刻的转型。本研究利用中国健康与营养调查(CHNS)2004 年至 2011 年的纵向数据,旨在更好地理解农村地区城市化与饮食转型之间的关系,重点关注营养摄入和饮食质量。我们的研究结果表明,随着城市化程度的提高,农村居民的平均热量摄入降低,但饮食质量提高。具体来说,城市化程度的提高持续降低碳水化合物的摄入,在转折点后降低脂肪的摄入;在转折点后,随着城市化程度的提高,蛋白质的摄入先下降后上升。城市化对健康饮食指数(HEI)有显著的积极影响。除了社会人口变化,我们还发现,消费者偏好和知识的变化是解释 2004 年至 2011 年中国农村饮食转型的重要决定因素。在本研究中,城市化似乎对农村居民的健康食品偏好和饮食知识产生积极影响。本研究首次尝试更好地理解中国农村加速城市化所带来的营养转型;同时也强调了一些局限性和未来研究的方向。
