修订中国膳食平衡指数

THE CHINESE DIET BALANCE INDEX REVISED

目的依据2007年发布的中国居民膳食指南和平衡膳食宝塔,修订中国膳食平衡指数DBI-07。方法利用膳食指南中的核心条目选择构成膳食平衡指数的单项食物指标,包括谷类食物、蔬菜水果、奶类及大豆类、动物性食物、酒精和调味品、食物种类以及饮水量。参照平衡膳食宝塔建议的食物摄入量确定每个单项指标的分值及计分方法,以负端分(LBS)、正端分(HBS)、膳食质量距(DQD)的方法进行计分评价。应用DBI-07对2002年中国居民营养与健康调查中26300名18～79岁成年人进行膳食质量评价。结果人群中负端分的均值为11.5,78%的人存在中、高度的摄入不足。正端分的均值为30.0,有35.1%的人存在中、高度的摄入过量。膳食质量距的均值为41.5,有43.8%的人存在高度的膳食不均衡。结论DBI-07的定义及评价方法,反映了中国居民膳食指南的基本原理,既能反映摄入不足又能反映摄入过量,可用于评价群体和个体的膳食营养状况。

To revise Chinese Diet Balance Index （DBI） based on the current Chinese Dietary Guidelines and Food Guide Pagoda . Method： Seven food components [（cereals ,vegetables and fruits, bean and dairy , animal food , alcohol ,condiments （salt and edible oil））were selected in combination with food varieties and drinking water to build up Diet Balance Index Revision （DBI-07） .The components were weighed and assigned cut-offs and scores based on the Chinese Food Guide Pagoda. Three scoring methods （LBS-low bound score, HBS-high bound score, DQD-diet quality distance） were used to evaluate the dietary quality of 26300 adults aged 18 to 79 years from 2002 China National Nutrition and Health Survey. Results： The mean LBS, HBS and DQD were 11.5,30.0 and 41.5 respectively. About 78% adult were in moderate or severe deficit of food intake, 35.1% in moderate or severe surplus of food intake, and 43.8% in severe dietary imbalance. Conclusion： DBI-07 can reflect the principles of dietary guidelines, and the scoring method can reflect both deficit and surplus of food intake. DBI-07 can be used to evaluate the dietary quality of individual or the population.
