Abstract Objectives Dietary data are rarely collected in low- and middle-income countries due to complexity, cost, and time burden. To facilitate the collection and use of individual dietary data, the International Dietary Data Expansion (INDDEX) Project has developed INDDEX24, a novel dietary assessment platform to collect and analyze 24-hr dietary recall (24HR) data. This study assessed the cost and cost-efficiency (cost per respondent) of INDDEX24 compared to the traditional pen-and-paper interview (PAPI) approach to collecting and processing 24HR data. Methods Conducted alongside validation studies of the INDDEX24 platform in Viet Nam and Burkina Faso, we carried out activity-based costing studies to estimate and compare the cost of using INDDEX24 and PAPI to conduct a 24HR survey. We defined and costed a series of activities required to complete data collection and prepare the datasets, including development of dietary reference data, survey preparation, training, survey execution, data entry, and data cleaning and processing. Results In Viet Nam, the total economic cost of the 24HR was $111,004 ($755/respondent, n = 147) using INDDEX24 and $120,483 ($820/respondent, n = 147) using the PAPI modality. In Burkina Faso, the total cost of the 24HR using INDDEX24 was $78,043 ($538/respondent, n = 145) and $78,933 ($541/respondent, n = 146) using PAPI. The higher costs in Viet Nam were primarily driven by the preparation of dietary reference data, which was an extensive and nationally focused effort, whereas in Burkina it was regionally focused and benefited from previous development of relevant dietary data. In both countries, while INDDEX24 had higher costs associated with survey preparation (including purchasing tablets and a CommCare subscription), these costs were more than offset by the higher PAPI costs associated with data entry and data cleaning and processing. Conclusions In two distinct contexts, the cost of conducting a 24HR was lower (Viet Nam) or approximately equivalent (Burkina Faso) using INDDEX24 than using PAPI. As the INDDEX24 dietary reference database is populated with reference data from which future users of INDDEX24 can draw, the cost of using INDDEX24 will likely decline further.

Abstract Objectives Regular collection and use of dietary data, particularly in low- and middle-income countries (LMICs), is hindered by the lack of available and accessible dietary data research infrastructure (e.g., accessible food composition tables (FCT), portion conversions, and standard recipes; electronic dietary assessment tools). INDDEX24 is a global dietary assessment platform that addresses these bottlenecks. Methods Priority technical specification were drafted and reviewed by experts with extensive dietary assessment experience in LMICs. Specifications included use of the multiple pass 24-hour dietary recall method, offline data collection capability, contextual adaptability, and an interviewer-administered format. Existing dietary assessment platforms were evaluated against the technical specifications via a structured literature review and key informant interviews. An initial version of INDDEX24 was developed and tested through feasibility studies in Vietnam and Burkina Faso. Feedback from potential users of the platform was gathered during webinars. The platform was subsequently revised, and its relative validity, time, and cost compared to use of paper-based 24-hour dietary recalls were then evaluated in Vietnam and Burkina Faso. Results INDDEX24 is comprised of a mobile application (app) that is linked with a web app. The web app is used by researchers to manage the dietary data inputs for their survey context (i.e., FCT data, recipes, food descriptors, and portion conversions). Users can search the web app for dietary data inputs and integrate them into their workspace or upload their own inputs. The INDDEX24 mobile app is a 24-hour dietary recall app that has been built using CommCare mobile platform technology. Users can adapt mobile app questionnaire text to their survey language and context, add survey modules, conduct data monitoring, and basic food matching. To maximize the time and cost saving benefits of the platform, a concerted effort will be needed to populate the web app with dietary data inputs from LMICs. Conclusions The extensive consultative process and evidence driven design has produced a high-quality platform that balances flexibility of adaptation to a range of contexts with quality control and standardization.

Abstract Objectives This study assessed the accuracy and user experience of the INDDEX24 platform compared to a traditional pen and paper (PAPI) 24HR in Burkina Faso and Viet Nam. INDDEX24 is a dietary assessment platform, developed by the International Dietary Data Expansion (INDDEX) Project, which links a tablet-based platform for conducting individual 24HR to a set of web-based dietary data inputs (food composition database, standard recipes, conversion factors). Methods We used quantitative and qualitative methods. INDDEX24 and PAPI 24HR modalities were compared against the benchmark method, Weighed Food Records (WFR). Outcomes were energy intake, macronutrients, select micronutrients, and food groups. To assess the user experience, we conducted focus groups with field staff, who also completed a short questionnaire. Needed sample size was 234 women, 117 for each arm, based on Pearson's correlation >0.6 with type I error set at 5% and power at 80%. Data collection included a full day of direct observation for the WFR, followed by a single 24HR. Socio-demographic data were also collected. Quantitative data were analyzed with Stata v15.1; qualitative data with NVivo 11. Results A total of 231 rural women in Burkina Faso and 234 rural women in Viet Nam, aged 18–49 years, were enrolled August-October 2019 and assigned to a study arm. Mean (±SD) age of participants was 29.7 (±8.4) (Burkina Faso) and 35.2 (±8.3) years (Viet Nam). Most respondents in Viet Nam completed some secondary school or higher (94.9%); in Burkina Faso most respondents (83.4%) had no formal education; 3.2% had secondary school level or higher. There were no statistically significant differences in age, education, pregnancy, and breastfeeding status between the two arms in either country. Field staff preferred using INDDEX24 to PAPI and provided some suggestions for improvement. Conclusions The study was successfully implemented in Burkina Faso and Viet Nam. The required sample size was obtained with balanced study arms. Qualitative feedback from field staff confirmed the superiority of INDDEX24 from a user perspective. The results will be important for fine tuning INDDEX24 for future use. The set of dietary data inputs developed for this study will remain in the public domain and be useful for researchers, saving time and cost for future surveys.

Abstract Objectives Collection of individual level dietary data in low and middle income countries traditionally has been hindered by complexity and high costs. To address this issue, the International Dietary Data Expansion (INDDEX) Project has developed an innovative dietary assessment platform (INDDEX24) consisting of a tablet-based application for conducting individual 24-hour dietary recalls (24HR), linked to a set of web-based dietary data inputs (e.g., food composition database, standard recipes, conversion factors). The objective of this study was to compare cost, time and cost effectiveness of a 24HR using INDDEX24 versus a standard pen-and-paper (PAPI) approach. Methods Costs of implementing 24HR using INDDEX24 vs. PAPI were derived using activity-based costing methods as part of two validation studies conducted with adult women in Burkina Faso (n = 231) and Viet Nam (n = 234). To estimate the time of survey administration, we surveyed 60 respondents per country in urban and rural areas. Other costed activities included: developing dietary data inputs, survey preparation and implementation, data entry, processing, and analysis. Monetary and time costs were compared in total and for each activity. Cost effectiveness was defined as relative cost per unit of accuracy, with accuracy determined by the difference of INDDEX24 and PAPI compared to a weighed food record (WFR). Results This study identified multiple challenges associated with assessing the cost side of a cost-effectiveness analysis. The overall cost, time, and cost-effectiveness can vary significantly by country, as well as by specific activities in each context. Another challenge was distinguishing costs related to the implementation of the INDDEX24 validation study from those that future users will face. Modeled scenarios distinguished the up-front costs of developing and validating the INDDEX24 platform from the expected implementation costs of using it. Conclusions The selection of the most appropriate dietary assessment approach should be based on considerations of time, cost, and accuracy. This cost study, together with findings from the INDDEX24 validation study, shows the potential for INDDEX24 to streamline 24HR by saving time and resources.

Abstract Objectives The study assessed the relative accuracy of INDDEX24, a computer-assisted personal interview (CAPI) approach to conducting a 24-hour dietary recall (24HR), compared to the pen-and-paper interview (PAPI) approach against a full-day observed weighed food record (WFR) in northern Viet Nam where the diet is diverse and complex. Methods Women aged 18–49 from northern Viet Nam were randomly assigned to be interviewed with the CAPI or PAPI 24HR the day after other enumerators conducted a WFR. The Two One Sided T-test (TOST) assessed equivalence of each recall-benchmark method comparison using a 10% bound. A difference-in-differences approach compared the significance of differences between the CAPI vs. WFR and PAPI vs. WFR modalities. Nutrient intakes were logged to achieve a normal distribution. Results Both the PAPI and the CAPI were statistically equivalent to the WFR across indicators of average total food items, total grams of intake, energy intake, all macro- and micronutrients tested (except Vitamin A for both CAPI and PAPI). The difference-in-difference analysis showed that the CAPI diverged significantly less than PAPI from the WFR for iron (0.9 v. −1.3 mg) and PAPI diverged less from the WFR than CAPI for protein (−3.7 v. 7.9 grams). There were no other statistically significant differences and, for both PAPI and CAPI, average deviations from the WFR were small. Individual-level comparisons showed 56% of PAPI and 59% of CAPI respondents were within +/−20% of the WFR intakes, while 26% of respondents in the PAPI group and 32% of the CAPI group had energy intakes by 24HR within +/- 10% of the WFR intakes. Conclusions INDDEX24 was an accurate method for assessing food and nutrient intake among women of reproductive age in northern Viet Nam, when compared to a WFR. INDDEX24 performed at least as well as the PAPI 24HR modality across several different group and individual level measures for energy and nutrients of interest. Digital data collection platforms facilitate standardization of data collection and may reduce survey time and costs. Given these advantages, the INDDEX24 Dietary Assessment Platform should be considered for implementing high quality, individual-level, quantitative dietary surveys in low- and middle-income countries.

This scoping review focuses on the assessment of commensality in research and attempts to identify used methods for performing research on commensality. It reflects a multidisciplinary research field and draws on findings from Web of Science Core Collection, up to April 2019. The empirical material consisted of 61 studies, whereof most were qualitative research, and some were of quantitative character, including very few dietary surveys. The findings show nine papers categorized as using quantitative approaches, 52 papers were categorized as qualitative. The results show a wide variety of different ways to try to find and understand how commensality can be understood and identified. There seems to be a shift in the very concept of commensality as well as some variations around the concept. This paper argues the need to further investigate the importance of commensality for health and wellbeing, as well as the need to gather data on health and health-related behaviors, living conditions and sociodemographic data in parallel. The review shows the broad-ranging areas where commensality is researched, from cultural and historical areas to ethnographic or anthropological areas over to dietary assessment. To complement large dietary surveys with methods of assessing who you are eating with in what environment should be a simple way to further our knowledge on the circumstances of meal intake and the importance of commensality. To add 24-h dietary recall to any study of commensality is another way of identifying the importance of commensality for dietary quality. The use of mixed methods research was encouraged by several authors as a good way forward in the assessment of commensality and its importance.

Abstract Objective To analyse data from 2016–17 from a hospital-based antimicrobial resistance surveillance with national coverage in a network of hospitals Viet Nam. Methods We analysed data from 13 hospitals, 3 less than the dataset from the 2012–13 period. Identification and antimicrobial susceptibility testing data from the clinical microbiology laboratories from samples sent in for routine diagnostics were used. Clinical and Laboratory Standards Institute 2018 guidelines were used for antimicrobial susceptibility testing interpretation. WHONET was used for data entry, management and analysis. Results 42,553 deduplicated isolates were included in this analysis; including 30,222 (71%) Gram-negative and 12,331 (29%) Gram-positive bacteria. 8,793 (21%) were from ICUs and 7,439 (18%) isolates were from invasive infections. Escherichia coli and Staphylococcus aureus were the most frequently detected species with 9,092 (21%) and 4,833 isolates (11%), respectively; followed by Klebsiella pneumoniae (3,858 isolates – 9.1%) and Acinetobacter baumannii (3,870 isolates – 9%). Bacteria were mainly isolated from sputum (8,798 isolates – 21%), blood (7,118 isolates – 17%) and urine (5,202 isolates – 12%). Among Gram-positives 3,302/4,515 isolates (73%) of S. aureus were MRSA; 99/290 (34%) of Enterococcus faecium were resistant to vancomycin; and 58% (663/1,136) of Streptococcus pneumoniae proportion were reduced susceptible to penicillin. Among Gram-negatives 59% (4,085/6,953) and 40% (1,186/2,958) of E. coli and K. pneumoniae produced ESBL and 29% (376/1,298) and 11% (961/8,830) were resistant to carbapenems, respectively. 79% (2855/3622) and 45% (1,514/3,376) of Acinetobacter spp. and Pseudomonas aeruginosa were carbapenem resistant, respectively. 88% (804/911) of Haemophilus influenzae were ampicillin resistant and 18/253 (7%) of Salmonella spp. and 7/46 (15%) of Shigella spp. were resistant to fluoroquinolones. The number of isolates from which data were submitted in the 2016–2017 period was twice as high as in 2012–2013. AMR proportions were higher in 2016–2017 for most pathogen-antimicrobial combinations of interest including imipenem-resistant A. baumannii, P. aeruginosa and Enterobacterales. Conclusions The data show alarmingly high and increasing resistant proportions among important organisms in Viet Nam. AMR proportions varied across hospital types and should be interpreted with caution because existing sampling bias and missing information on whether isolates were community or hospital acquired. Affordable and scalable ways to adopt a sample- or case-based approach across the network should be explored and clinical data should be integrated to help provide more accurate inferences of the surveillance data.

Abstract Objective: To describe existing online 24-hour dietary recall (24hDR) tools in terms of functionalities and ability to tackle challenges encountered during national dietary surveys, such as maximizing response rates and collecting high-quality data from a representative sample of the population, while minimizing the cost and response burden. Design: A search (from 2000 to 2019) was conducted in peer-reviewed and grey literature. For each tool, information on functionalities, validation and user usability studies, and potential adaptability for integration into a new context was collected. Setting: Not country-specific Participants: General population Results: Eighteen online 24hDR tools were identified. Most were developed in Europe, for children ≥10 years old and/or for adults. Eight followed the five multiple-pass steps, but used various methodologies and features. Almost all tools (except three) validated their nutrient intake estimates, but with high heterogeneity in methodologies. User usability was not always assessed, and rarely by applying real-time methods. For researchers, eight tools developed a web platform to manage the survey and five appeared to be easily adaptable to a new context. Conclusions: Among the eighteen online 24hDR tools identified, the best candidates to be used in national dietary surveys should be those that were validated for their intake estimates, had confirmed user and researcher usability, and seemed sufficiently flexible to be adapted to new contexts. Regardless of the tool, adaptation to another context will still require time and funding, and this is probably the most challenging step.

AbstractObjective:To evaluate the 137-item Utah Picture-sort Food-frequency Questionnaire (FFQ) in the measurement of usual dietary intake in older adults.Design:The picture-sort FFQ was administered at baseline and again one year later. Three seasonal 24-hour dietary recall interviews were collected during the year between the two FFQs. Mean nutrient intakes were compared between methods and between administrations of the FFQ.Setting:The FFQ interviews were administered in respondents' homes or care-centres. The 24-hour diet recalls were conducted by telephone interview on random days of the week.Subjects:Two-hundred-and-eight men and women aged 55–84 years were recruited by random sample of controls from a case–control study of nutrition and bone health in Utah.Results:After adjustment for total energy intake, median Spearman rank correlation coefficients between the two picture-sort FFQs were 0.69 for men aged ≤69 years, 0.66 for men aged >69 years; and 0.68 for women aged ≤69 years, 0.67 for women aged >69 years. Median correlation coefficients between methods were 0.50 for men ≤69 years old, 0.52 for men >69 years old; 0.55 for women ≤69 years old, 0.46 for women >69 years old.Conclusions:We report intake correlations between methods and administrations comparable to those reported in the literature for traditional paper-and-pencil FFQs and one other picture-sort method of FFQ. This dietary assessment method may improve ease and accuracy of response in this and other populations with low literacy levels, poor memory skill, impaired hearing, or poor vision.
