Abstract

Overweight and obesity are rapidly growing threats in China. Improvement in dietary knowledge can potentially prevent overweight and obesity, conditions which are receiving substantial attention from international organizations and governments. The purpose of this study was to investigate the impact of changes in dietary knowledge on adult overweight and obesity, using a balanced panel data consisting of 10,401 samples from the 2006, 2009, and 2011 iterations of the China Health and Nutrition Survey. Results indicate that overweight and obesity are becoming increasingly problematic in China, and the level of dietary knowledge among Chinese adults needs improvement. Moreover, the empirical results indicate that changes in dietary knowledge among adults has no significant influence on adult overweight and obesity, a likely result of lacking systematic dietary knowledge and having inadequate guidance on overweight/obesity-related behaviors.

摘要

超重和肥胖在中国正迅速成为日益严重的威胁。饮食知识的改善有可能预防超重和肥胖,这些情况正受到国际组织和各国政府的高度关注。本研究的目的是利用来自中国健康与营养调查2006年、2009年和2011年三轮调查的10401个样本组成的平衡面板数据,调查饮食知识变化对成年人超重和肥胖的影响。结果表明,超重和肥胖在中国正变得越来越成问题,中国成年人的饮食知识水平有待提高。此外,实证结果表明,成年人饮食知识的变化对成年人超重和肥胖没有显著影响,这可能是缺乏系统的饮食知识以及在超重/肥胖相关行为方面缺乏足够指导的结果。
