Dietary assessment in minority ethnic groups is critical for surveillance programs and for implementing effective interventions. A major challenge is the accurate estimation of portion sizes for traditional foods and dishes.
The aim of this systematic review was to assess records published up to 2014 describing a portion-size estimation element (PSEE) applicable to the dietary assessment of UK-residing ethnic minorities.
DATA SOURCES, SELECTION, AND EXTRACTION: Electronic databases, internet sites, and theses repositories were searched, generating 5683 titles, from which 57 eligible full-text records were reviewed.
Forty-two publications about minority ethnic groups (n = 20) or autochthonous populations (n = 22) were included. The most common PSEEs (47%) were combination tools (eg, food models and portion-size lists), followed by portion-size lists in questionnaires/guides (19%) and image-based and volumetric tools (17% each). Only 17% of PSEEs had been validated against weighed data.
When developing ethnic-specific dietary assessment tools, it is important to consider customary portion sizes by sex and age, traditional household utensil usage, and population literacy levels. Combining multiple PSEEs may increase accuracy, but such methods require validation.
少数民族的饮食评估对于监测项目和实施有效干预措施至关重要。一个主要挑战是准确估计传统食物和菜肴的份量。
本系统评价的目的是评估截至2014年发表的记录，这些记录描述了适用于对居住在英国的少数民族进行饮食评估的份量估计要素（PSEE）。
数据来源、选择和提取：检索了电子数据库、互联网站点和论文库，共生成5683个标题，从中筛选出57篇符合条件的全文记录进行评审。
纳入了42篇关于少数民族群体（n = 20）或原住民群体（n = 22）的出版物。最常见的PSEE（47%）是组合工具（如食物模型和份量列表），其次是问卷/指南中的份量列表（19%）以及基于图像和体积的工具（各占17%）。只有17%的PSEE已根据称重数据进行了验证。
在开发针对特定族裔的饮食评估工具时，考虑按性别和年龄划分的习惯份量大小、传统家用器具的使用情况以及人群识字水平非常重要。结合多种PSEE可能会提高准确性，但此类方法需要进行验证。
