目的:全球饮食数据库(GDD)扩展了其先前的方法,以协调和公开传播来自全球营养调查的个人水平饮食数据。
方法:横截面数据分析。
方法:全局。
方法:一般人群。
方法:简化初级、制定了全球个人24小时召回和食品记录数据。为了标准化不同的食物描述,使用了FoodEx2,EFSA开发并调整为国际使用的高度详细的食品分类和描述系统。制定了标准化程序,以:确定合格的调查;联系数据所有者;筛选调查以纳入;协调数据结构,变量定义和单位,和食品特征;进行数据检查;并公开传播统一的数据集。GDD与粮农组织和EFSA联手,考虑到全球统一个人水平饮食数据的共同目标。
结果:在确定的1,500项饮食调查中,600符合资格标准,和156项被优先排序和联系;55项调查被纳入协调范围,最终,52是统一的。纳入的调查主要具有全国代表性(59%);包括高(39%),中上(21%),中下层(27%),和低收入(13%)国家;通常收集多次召回/记录(64%);并在很大程度上记录了两性,所有年龄,农村和城市地区。低收入和中低收入国家与高收入和中高收入国家的调查报告的营养素较少(中位数为17vs.30),很少包括与饮食相关的慢性疾病相关的营养素,如ω-3脂肪酸和钠。
结论:可以协调不同的24小时召回/记录,以提供高度细粒度的,标准化数据,支持营养规划,研究,和全球能力发展。
OBJECTIVE: The Global Dietary Database (GDD) expanded its previous methods to harmonise and publicly disseminate individual-level dietary data from nutrition surveys worldwide.
METHODS: Analysis of cross-sectional data.
METHODS: Global.
METHODS: General population.
METHODS: Comprehensive methods to streamline the
harmonisation of primary, individual-level 24-h recall and food record data worldwide were developed. To standardise the varying food descriptions, FoodEx2 was used, a highly detailed food classification and description system developed and adapted for international use by European Food Safety Authority (EFSA). Standardised processes were developed to: identify eligible surveys; contact data owners; screen surveys for inclusion; harmonise data structure, variable definition and unit and food characterisation; perform data checks and publicly disseminate the harmonised datasets. The GDD joined forces with FAO and EFSA, given the shared goal of harmonising individual-level dietary data worldwide.
RESULTS: Of 1500 dietary surveys identified, 600 met the eligibility criteria, and 156 were prioritised and contacted; fifty-five surveys were included for
harmonisation and, ultimately, fifty two were harmonised. The included surveys were primarily nationally representative (59 %); included high- (39 %), upper-middle (21 %), lower-middle (27 %) and low- (13 %) income countries; usually collected multiple recalls/ records (64 %) and largely captured both sexes, all ages and both rural and urban areas. Surveys from low- and lower-middle v. high- and upper-middle income countries reported fewer nutrients (median 17 v. 30) and rarely included nutrients relevant to diet-related chronic diseases, such as n-3 fatty acids and Na.
CONCLUSIONS: Diverse 24-h recalls/records can be harmonised to provide highly granular, standardised data, supporting nutrition programming, research and capacity development worldwide.
