摘要

背景：由于缺乏直接实用的指标来跟踪儿童和青少年的饮食质量，对全球要求更多儿童和青少年饮食和营养数据的响应受到限制。根据由10个食物组（FGS-10）编制的食物组得分，女性的最低饮食多样性（按FGS-10≥5计算）是低收入和中等收入国家（LMICs）成年女性更好的微量营养素摄入充足性的有效代理人口指标。目的：本研究旨在验证FGS-10及其与中低收入国家4-15岁儿童/青少年微量营养素摄入充足性的相关截止值。方法：我们对2007年至2022年间7个国家（布基纳法索、加纳、厄瓜多尔、印度、马拉维、乌干达和赞比亚）的11,524名4-15岁儿童/青少年的24小时重复召回或称重记录的9个数据集进行了二次数据分析。对于每个数据集和汇总样本（荟萃分析），我们评估了FGS-10与摄入超过8种微量营养素（MPA-8）的平均充足概率（MPA）之间的关系，以及几个FGS-10截止点在预测MPA-8可接受（≥0.60）和良好（≥0.80）水平方面的表现。鲁棒性分析使用7个数据集和11种微量营养素（MPA-11）的数据。结果：各数据集的FGS-10评分范围为3.0 - 4.8，可接受MPA-8的儿童/青少年比例为8.4% - 74%。在所有数据集和合并样本中，FGS-10和MPA-8之间均存在显著正相关。从FGS-10≥4到FGS-10≥6，各数据集的最佳截止值各不相同。在合并的样本中，FGS-10≥5在预测MPA-8的可接受和良好水平方面具有最高的性能。FGS-10≥5也是MPA-11≥0.80的最佳代理指标。结论：连续的FGS-10和二分的FGS-10≥5可以扩展到低收入国家4-15岁的儿童/青少年。在该人群中，FGS-10≥5可作为膳食中微量营养素充足性良好的替代人群指标。

The Minimum Dietary Diversity For Women Indicator Can Be Extended To Children And Adolescents aged 4-15 Years As A Proxy Population Indicator For Good Micronutrient Adequacy Of Diets In Low- and Middle-Income Countries

Background

The response to the global call for more data on children’s and adolescents’ diets and nutrition is limited by the lack of straightforward practical indicators to track their diet quality. On the basis of a food group score compiled from 10 food groups (FGS-10), the minimum dietary diversity for women, calculated as FGS-10 ≥ 5, is a validated proxy population indicator for better micronutrient intake adequacy for adult women in low- and middle-income countries (LMICs).

Objectives

This study aims to validate FGS-10 and its related cutoffs against micronutrient intake adequacy in 4–15-y-old children/adolescents in LMICs.

Methods

We conducted a secondary data analysis of 9 datasets of repeated 24-h recalls or weighed records including 11,524 children/adolescents aged 4–15 y, collected in 7 countries (Burkina Faso, Ghana, Ecuador, India, Malawi, Uganda, and Zambia) between 2007 and 2022. For each dataset and the pooled sample (meta-analysis), we assessed the association between FGS-10 and the mean probability of adequacy (MPA) of intake over 8 micronutrients (MPA-8), and the performance of several FGS-10 cutoffs in predicting acceptable (≥0.60) and good (≥0.80) levels of MPA-8. Robustness analyses used the 7 datasets with data on 11 micronutrients (MPA-11).

Results

FGS-10 ranged from 3.0 to 4.8 across datasets, and the proportion of children/adolescents with acceptable MPA-8 ranged from 8.4% to 74%. Positive and significant associations between FGS-10 and MPA-8 were found in all datasets and the pooled sample. The optimal cutoff varied across datasets from FGS-10 ≥ 4 to FGS-10 ≥ 6. In the pooled sample, FGS-10 ≥ 5 had the highest performances in predicting acceptable and good levels of MPA-8. FGS-10 ≥ 5 was also the best proxy indicator for MPA-11 ≥ 0.80.

Conclusions

The continuous FGS-10 and dichotomous FGS-10 ≥ 5 may be extended to 4–15-y-old children/adolescents in LMICs. In this population, FGS-10 ≥ 5 can be used as a proxy population indicator for good micronutrient adequacy of diets.
