HIDDEN HUNGER

This dataset is of the manuscript “Beyond Weekdays: Weekend Dietary Intake Uncovers Hidden Micronutrient Deficiencies in Institutionalised Children”. It contains dietary data and related documentation from assessing diet quality and micronutrient adequacy among institutionalised children in northern Mexico.
The repository includes:
Scenario-based dietary databases:
Weekday-only intake (Reg): Two 24-hour food records collected within the institution.
Weekday + Sunday intake (Reg+R24): Two 24-hour records plus a 24-hour recall for Sunday, capturing weekend dietary patterns.
Plausible reporters database:
A dataset of participants was classified as plausible energy reporters based on the Goldberg and Black method and physical activity data from the PAU-7S questionnaire.
Supporting documentation:
Blank informed consent and assent forms (English version) were used for participant enrollment.
Codebooks describing the variables and data structure of the dietary databases.
File format: Excel spreadsheets (.xlsx) for dietary data, PDF for blank consent/assent forms.
Use of data: All data are anonymised and intended for reproducibility, meta-analysis, or methodological comparison.

本数据集对应学术稿件《超越工作日：周末膳食摄入揭示收容机构儿童隐匿的微量营养素缺乏》（*Beyond Weekdays: Weekend Dietary Intake Uncovers Hidden Micronutrient Deficiencies in Institutionalised Children*），涵盖针对墨西哥北部收容机构儿童的膳食质量与微量营养素充足性评估所产生的膳食数据及相关文档。

数据集包含以下内容：
一、基于场景的膳食数据库
1. 仅工作日膳食摄入数据集（Reg）：采集自机构内的2份24小时膳食记录（24-hour food records）；
2. 工作日+周日膳食摄入数据集（Reg+R24）：包含2份24小时膳食记录与1份周日24小时膳食回顾（24-hour recall），用于捕捉周末膳食模式。
二、可信报告者数据库
基于戈德堡-布莱克法（Goldberg and Black method）与PAU-7S身体活动问卷采集的活动数据，将受试者归类为可信能量报告者后构建的数据集。
三、辅助文档
1. 用于受试者招募的空白英文版本知情同意书与儿童同意表单；
2. 说明膳食数据库变量与数据结构的编码手册。
四、文件格式
膳食数据采用Excel电子表格格式（.xlsx），空白知情同意/儿童同意表单采用PDF格式。
五、数据使用范围
所有数据均已完成匿名化处理，可用于研究可重复性验证、荟萃分析或方法学对比研究。
