In a world rapidly transitioning, food consumption away from home is rising, therefore representing an increasing share of individual's diet. Food consumed away from home negatively impacts diet, nutritional status and consequently has detrimental effects on health. In some contexts, where individual level dietary intake surveys are not regularly conducted, this behavior is not well documented leading to a gap of knowledge. The aim of the present study was to develop and validate in Burkina Faso and Vietnam specific modules that could be added to Household Consumption and Expenditure Surveys that are usually regularly conducted worldwide, in order to document the economic and nutritional importance of food consumption away from home. In each country, two survey modules, one long (100 food items) and one short (30 food items) were developed, to measure individual-level food consumption away from home over the last 7 days. The modules were relatively validated in comparison with data from three non-consecutive 24-hour dietary recalls conducted over the same 7-days period. The validation was conducted in different settings (urban, peri-urban and rural) in Burkina Faso (n = 924) and Vietnam (n = 918). In both countries, a good concordance between the 24-hour dietary recalls and the modules in their ability to identify a person as having consumed food away from home (>77%) was found. However, in both countries, both modules underestimate the mean energy intake coming from foods consumed away from home (from 122 to 408 kcal) while they overestimate the budget allocated to it (from -0.07 to -0.29 USD/day). None of developed food away from home modules were considered as valid. There is a need for the international community to continue to work on developing and validating tools capable to estimate nutritional intakes related to food consumption away from home and that could be added to regular national household-level surveys.
在一个迅速转型的世界中，外出就餐的消费正在增加，因此在个人饮食中所占份额也日益增大。外出就餐对饮食和营养状况产生负面影响，进而对健康产生有害影响。在一些未定期开展个人层面饮食摄入量调查的情况下，这种行为没有得到充分记录，导致知识缺口。本研究的目的是在布基纳法索和越南开发并验证特定模块，这些模块可添加到通常在全球定期开展的家庭消费和支出调查中，以记录外出就餐的经济和营养重要性。在每个国家，都开发了两个调查模块，一个长模块（包含100种食物）和一个短模块（包含30种食物），用于测量过去7天内个人层面的外出就餐食物消费情况。与在同一7天期间进行的三次非连续24小时饮食回顾数据相比，对这些模块进行了相对验证。验证在布基纳法索（n = 924）和越南（n = 918）的不同环境（城市、城郊和农村）中进行。在这两个国家，发现24小时饮食回顾与模块在识别一个人是否外出就餐方面的能力之间具有良好的一致性（>77%）。然而，在这两个国家，两个模块都低估了外出就餐食物的平均能量摄入量（相差122至408千卡），同时高估了为此分配的预算（相差-0.07至-0.29美元/天）。所开发的外出就餐模块均未被视为有效。国际社会需要继续致力于开发和验证能够估计与外出就餐食物消费相关的营养摄入量的工具，并且这些工具可添加到常规的国家家庭层面调查中。
