目的 依据2022年发布的《中国居民膳食指南》,修订中国膳食平衡指数DBI_22。方法 根据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。结果 DBI_22评价指标包括谷类食物、蔬菜水果、奶类及大豆类、动物性食物、纯能量食物、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、正端分、膳食质量距的方法进行计分评价。结论 DBI_22的定义及评价方法,反映了新版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。
Abstract
Objective To revise Chinese Diet Balance Index (DBI) based on the current Chinese dietary guidelines (2022). Methods The components were weighted and the cut–offs and score assigned based on the Chinese Food Guide Pagoda. Results Cereals, vegetable and fruit, bean and dairy, animal food, empty energy food, condiments were selected in cooperation with food variety and drinking water to build up revised Diet Balance Index (DBI_22). Score and scoring method for each individual indicator by referring to the food intake was determined by the balanced diet pagoda. Low Bound Score (LBS), High Bound Score (HBS) and Diet Quality Distance (DQD) were used to evaluate the dietary quality. Conclusion The DBI_22 reflects the principles of new dietary guideline, the scoring method can reflect both under and over intake. DBI_22 can be used as a measurement to evaluate the dietary quality of the individual or the population.
