目的 研究1991－2011年中国9省(自治区)18～44岁人群蔬菜、水果的摄入状况及变化趋势。方法 以“中国健康与营养调查”(CHNS)1991－2011年调查数据为基础,选择连续3天24 小时有完整膳食数据的18～44岁健康人群作为研究对象,计算该人群平均每天蔬菜、水果的摄入率及摄入量,并与《中国居民膳食指南》蔬菜、水果推荐摄入量进行比较。结果 1991－2011年中国9省(自治区)18～44岁人群蔬菜摄入率变化不大、摄入量下降明显;水果摄入率及摄入量不断提高,2011年调查人群蔬菜、水果摄入率及摄入量分别为99.7%、48.0%、321.6 g/d、90.1 g/d。蔬菜摄入量达到《中国居民膳食指南》推荐摄入量的人群比例显著下降,至2011年为50.2%;水果摄入量达到《中国居民膳食指南》推荐摄入量的人群比例显著上升,至2011年为17.4%。结论 中国9省(自治区)18～44岁人群蔬菜、水果平均摄入量仍低于《中国居民膳食指南》的推荐摄入量,应采取措施进一步促进该人群蔬菜和水果的摄入。

Trends of vegetables and fruits consumption among Chinese adults aged 18 to 44 years old from 1991 to 2011

Objective To identify the trends of vegetables and fruits consumption among Chinese adults aged 18 to 44 years old from 1991 to 2011. Methods Twenty four hour dietary recall data from China Health and Nutrition Survey (1991,1993,1997,2000,2004,2006,2009 and 2011) were used to identify the trends of vegetables and fruits consumption among Chinese between 18 and 44 years old. Results From 1991 to 2011,the proportion of daily consumption of vegetables rarely varied,while the vegetables intake declined significantly; and the proportion of daily consumption and intake of fruits kept increasing as follows. By 2011,the proportion of daily consumption and intake of vegetables and fruits among the respondents were 99.7%,48.0%,321.6 g/d, and 90.1 g/d respectively. A significant drop was found in the vegetables intake among the respondents against the vegetables intake as recommended by the Chinese dietary guidelines,up to 50.2% in 2011; a significant rise was found in the fruits intake of the respondents against the fruits intake as recommended by the said guidelines,up to 17.4% in 2011. Conclusion The average daily intake of vegetables and fruits of young and middle-aged residents (18-44 age group) in nine provinces in China was found lower than that recommended in the Chinese dietary guidelines; in view of the high proportion of people having less vegetables and fruits intake that those recommended by the Chinese dietary guidelines,further measures are expected to encourage their vegetables and fruits intake.
