The INDDEX24 Dietary Assessment Platform (INDDEX24) was developed to facilitate the collection of 24-h dietary recall (24HR) data. Alongside validation studies in Viet Nam and Burkina Faso in 2019-2020, we conducted activity-based costing studies to estimate the cost of conducting a 24HR among women of reproductive age using INDDEX24 compared with the pen-and-paper interview (PAPI) approach. We also modelled alternative scenarios in which: (1) 25-75 % of dietary reference data were borrowed from the INDDEX24 Global Food Matters Database (FMDB); (2) all study personnel were locally based and (3) national-scale surveys. In the primary analysis, in Viet Nam, the 24HR cost US $111 004 ($755/respondent, 147) using INDDEX24 and $120 483 ($820/respondent, 147) using PAPI. In Burkina Faso, the 24HR cost $78 105 ($539/respondent, 145) using INDDEX24 and $79 465 ($544/respondent, 146) using PAPI. In modelled scenarios, borrowing dietary reference data from the FMDB decreased the cost of INDDEX24 by 17-34 % (Viet Nam) and 5-15 % (Burkina Faso). With all locally based personnel, INDDEX24 cost more than PAPI ($498 . $448 per respondent in Viet Nam and $456 . $410 in Burkina Faso). However, at national scales ( 4376, Viet Nam; 6500, Burkina Faso) using all locally based personnel, INDDEX24 was more cost-efficient ($109 . $137 per respondent in Viet Nam and $123 . $148 in Burkina Faso). In two countries and under most circumstances, INDDEX24 was less expensive than PAPI. Higher INDDEX24 survey preparation costs (including purchasing equipment) were more than offset by higher PAPI data entry, cleaning and processing costs. INDDEX24 may facilitate cost-efficient dietary data collection.
INDDEX24 膳食评估平台(INDDEX24)旨在促进 24 小时膳食回顾(24HR)数据的收集。除了 2019 年至 2020 年在越南和布基纳法索进行的验证研究外,我们还进行了基于活动的成本研究,以估算使用 INDDEX24 进行生育年龄妇女 24HR 的成本与纸笔访谈(PAPI)方法相比。我们还对以下替代方案进行了建模:(1)从 INDDEX24 全球食物 Matters 数据库(FMDB)借用 25-75%的饮食参考数据;(2)所有研究人员均为本地人员;(3)国家规模的调查。在初步分析中,在越南,使用 INDDEX24 的 24HR 成本为 111004 美元(755 美元/受访者,147 人),使用 PAPI 的成本为 120483 美元(820 美元/受访者,147 人)。在布基纳法索,使用 INDDEX24 的 24HR 成本为 78105 美元(539 美元/受访者,145 人),使用 PAPI 的成本为 79465 美元(544 美元/受访者,146 人)。在建模方案中,从 FMDB 借用饮食参考数据使 INDDEX24 的成本降低了 17-34%(越南)和 5-15%(布基纳法索)。如果所有人员均为本地人员,则 INDDEX24 的成本将高于 PAPI(越南为 498 美元,448 美元/受访者;布基纳法索为 456 美元,410 美元/受访者)。但是,在全国范围内(越南 4376 人,布基纳法索 6500 人),如果所有人员均为本地人员,则 INDDEX24 的效率更高(越南为 109 美元,137 美元/受访者;布基纳法索为 123 美元,148 美元/受访者)。在这两个国家,并且在大多数情况下,INDDEX24 的成本都低于 PAPI。INDDEX24 较高的调查准备成本(包括设备采购)被 PAPI 更高的数据输入,清理和处理成本所抵消。INDDEX24 可能有助于实现具有成本效益的饮食数据收集。
