Abstract

BACKGROUND

There is little information in the literature on methods of food composition database development to calculate nutrient intake from food frequency questionnaire (FFQ) data. The aim of this study is to describe the development of an FFQ and a food composition table to calculate nutrient intake in a Black Zimbabwean population.

METHODS

Trained interviewers collected 24-hour dietary recalls (24 hr DR) from high and low income families in urban and rural Zimbabwe. Based on these data and input from local experts we developed an FFQ, containing a list of frequently consumed foods, standard portion sizes, and categories of consumption frequency. We created a food composition table of the foods found in the FFQ so that we could compute nutrient intake. We used the USDA nutrient database as the main resource because it is relatively complete, updated, and easily accessible. To choose the food item in the USDA nutrient database that most closely matched the nutrient content of the local food we referred to a local food composition table.

RESULTS

Almost all the participants ate sadza (maize porridge) at least 5 times a week, and about half had matemba (fish) and caterpillar more than once a month. Nutrient estimates obtained from the FFQ data by using the USDA and Zimbabwean food composition tables were similar for total energy intake intra class correlation (ICC) = 0.99, and carbohydrate (ICC = 0.99), but different for vitamin A (ICC = 0.53), and total folate (ICC = 0.68).

CONCLUSION

We have described a standardized process of FFQ and food composition database development for a Black Zimbabwean population.

摘要

背景

关于如何通过食物频率问卷（FFQ）数据计算营养摄入量来开发食物成分数据库的方法，文献中提供的信息很少。本研究的目的是描述如何开发一份FFQ和一份食物成分表，以计算津巴布韦黑人人群的营养摄入量。

方法

训练有素的访谈员收集了津巴布韦城乡高收入和低收入家庭的24小时饮食回顾（24小时DR）。基于这些数据以及当地专家的意见，我们开发了一份FFQ，其中包含常见食用食物清单、标准份量以及食用频率类别。我们创建了一份FFQ中所包含食物的食物成分表，以便能够计算营养摄入量。我们将美国农业部（USDA）营养数据库作为主要资源，因为它相对完整、更新及时且易于获取。为了在美国农业部营养数据库中选择与当地食物营养成分最匹配的食物项目，我们参考了一份当地食物成分表。

结果

几乎所有参与者每周至少吃5次萨扎（玉米粥），约一半的人每月吃马特姆巴（鱼）和毛虫不止一次。使用美国农业部和津巴布韦食物成分表从FFQ数据中获得的营养估计值，在总能量摄入量（组内相关系数[ICC]=0.99）和碳水化合物（ICC=0.99）方面相似，但在维生素A（ICC=0.53）和总叶酸（ICC=0.68）方面有所不同。
