Nutrition is central to the health, well-being, and economic development of individuals, communities, and nations. Comprehensive and credible data are needed to capture the current state of nutrition and track the implementation of nutrition interventions. The DHS Program is a leading source of nutrition data in low and middle-income countries.
The DHS Program has standard Model Questionnaires, updated every 5 years, which form the basis for the data that are collected in each country. In 2019, we underwent a rigorous process to update the questionnaires for DHS-8. A total of 89 nutrition-related questions are now in the Woman’s Questionnaire, up from 54 questions in DHS-7.
The DHS-8 questionnaires meet several current and emerging nutrition data needs which can be used to track progress and inform national and global decisions on nutrition policies and programs. This week we are highlighting the new and revised nutrition questions in DHS-8.
These new and revised questions strengthen the nutrition portfolio in DHS surveys, filling major data gaps and enhancing countries’ ability to address malnutrition in all its forms.

in late 2020 with data released starting in late 2021. In the meantime, The
DHS Program will:
Translate the questionnaires
Revise training manuals and materials
Develop an adaptation guide for questions which require country-specific adaptation, such as infant and young child feeding and minimum dietary diversity for women
Create data processing applications
Define indicators, design table templates, and draft report templates
Pilot select new questions, modules, and alternative approaches for entering data in CAPI
Global momentum on quality of care in the health system continues to expand. The United Nations Decade of Action on Nutrition (2016-2025) recognizes that the health system is a key pillar in providing universal coverage of essential nutrition actions. Reliable data for monitoring is central to understanding and improving the health system for nutrition. In addition to data from Health Management Information Systems, Service Provision Assessment (SPA) surveys also provide nationally representative facility information that can be used to explore the quality of facility-based health services.
SPA surveys are a rich source of nutrition information providing insight on the availability and quality of services. Similarly, DHS surveys provide a significant amount of information about nutrition behaviors of populations. By linking SPA and DHS surveys, users can examine how the health facility environment contributes to these behaviors.
Two recently released DHS Working Papers examine the health service environment for key nutrition interventions: breastfeeding counseling and iron folic acid supplementation. The papers use Haiti and Malawi as case studies to describe the facility readiness, such as the availability of trained providers and essential medicines (see infographics below), and service delivery including observations of provider-client consultations of the two interventions in the context of antenatal care. The papers go on further to link SPA and DHS surveys to examine relationships between the health service environment and the nutrition behaviors.
The papers illustrate how linking SPA and DHS surveys can be useful for enhancing essential nutrition actions at the facility by identifying key programmatic gaps that can be strengthened to improve effective intervention coverage.

This blog post is part of Luminare, our new blog series exploring innovative solutions to data collection, quality assurance, biomarker measurement, data use, and further analysis. This is the first post in the series that focuses on innovations to improve the quality of anthropometry data.
Anthropometry, the measurement of the human body, gives a snapshot of the malnutrition situation in a country. Yet, the collection of accurate height and weight measurements, especially for young children, is difficult during data collection. To address this challenge, The DHS Program has tested new innovations to enhance the quality of the anthropometry data in the 2018 Nigeria Demographic and Health Survey (NDHS).
The 2018 NDHS is the sixth DHS survey conducted in Nigeria. The National Population Commission (NPC), in collaboration with the National Malaria Elimination Programme (NMEP) of the Federal Ministry of Health (FMOH), implemented the survey. Thirty-seven field teams closely monitored by coordinators and quality controllers collected data from August 14, 2018, to December 29, 2018. Each field team included a supervisor, field editor, two male interviewers, three female interviewers, and a biomarker team consisting of a lab scientist and nurse.
Introducing a Biomarker Checklist to strengthen supervision
The DHS Program has developed a Biomarker Checklist to assess the performance of and provide feedback to field staff. The checklist includes a core set of tasks required to collect biomarker data. Each task is a crucial action that, if missed, can result in poor quality data. The Biomarker Checklist is administered by supervisors and coordinators during collection of biomarkers in households.
The Biomarker Checklist was tested during the 2018 NDHS pre-test and biomarker main training using a mixed-method design which included administering anonymous questionnaires and conducting key informant interviews with the supervisory staff who used the checklist to assess its’ viability and usefulness. Feedback on the Biomarker Checklist was positive, so the Biomarker Checklist was used during the 2018 NDHS data collection. A Biomarker Checklist will be publicly available at a later date.
“it [Biomarker Checklist] has helped a lot because you are able to monitor what the biomarkers are doing so [you] can actually give corrective action”
Reducing errors while still in the field through re-measurement of children
The shift from paper questionnaires to a CAPI-based data collection approach provides an opportunity to easily identify children who may have been mismeasured and return to the household to measure these children again. To identify children with incorrect measurements requires performing a complicated calculation – a child’s body measurements are compared against a healthy population by transforming their measurements into anthropometry Z-scores. Extreme measurement results are then detected by calculating anthropometry Z-scores and flagging cases with higher or lower Z-scores than expected. The DHS Program has developed a program to automatically calculate anthropometry Z-scores and flag extreme cases in the CAPI system. A user-friendly interface on the tablet produces a report with the children who need to be re-measured.
The DHS Program relies on field check tables that are run periodically during data collection. While an important data quality tool, a major limitation of the field check tables is that enough data need to accumulate before problems can be identified. At that point, the information can only be used to improve collection of data moving forward; these corrections do not fix data previously collected. The real-time ability to re-measure children while still in the field is a major step forward and can easily be applied to other CAPI surveys.
Re-measuring anthropometry in a random subsample of children
A random re-measurement of height and weight in a subsample of children was also piloted in Nigeria. The DHS Program has developed a CAPI program that randomly selects one household in each cluster for the biomarker team to revisit. The program then compares differences between measurements and reports precision, or how close the first measurement is to the second measurement, as acceptable or unacceptable.
The aim is measurements will be of better quality as a result of instituting random re-measurement. The biomarker team may be more careful and not rush measurements if they know poor measurements will be exposed. The data produced on precision can be used as a motivational tool for biomarker teams and provide an opportunity to identify and re-train in cases where there is a high degree of discrepancy between measurements.Precision estimates will also help better assess data quality post-data collection.
A review of the anthropometry data from the 2018 NDHS indicates it meets data quality targets. Results from the 2018 NDHS Key Indicators Report (KIR) show that 37% of children under 5 are stunted. Stunting generally increases with age, peaking at 47% for children age 24-35 months. Overall, 7% of children under 5 are wasted, while 23% of children are underweight.
Lessons learned in the implementation of the quality assurance activities in Nigeria are being used to conduct similar activities in DHS surveys in other countries.
About the survey
The 2018 NDHS was implemented by the National Population Commission (NPC) in collaboration with the National Malaria Elimination Programme (NMEP) of the Federal Ministry of Health, Nigeria. Funding for the 2018 NDHS was provided by the United States Agency for International Development (USAID), Global Fund, Bill and Melinda Gates Foundation (BMGF), the United Nations Population Fund (UNFPA), and World Health Organization (WHO). ICF provided technical assistance through The DHS Program, a USAID-funded project that provides support and technical assistance in the implementation of population and health surveys in countries worldwide.
Additional information about the 2018 NDHS may be obtained from the headquarters of the National Population Commission (NPC), Plot 2031, Olusegun Obasanjo Way, Zone 7, Wuse, P.M.B. 0281, Abuja, Nigeria (telephone: 234-09-523-9173; fax: 243-09-523-1024; email: firstname.lastname@example.org; internet: www.population.gov.ng).
The DHS Program, a leading source of nutrition data globally, has invigorated its focus on the quality and depth of the types of nutrition data collected. To this end, a qualitative study was undertaken to identify how to enhance the quality of nutrition data. Interviews were conducted with 50 experts internal and external to The DHS Program, and DHS staff participated in focus group discussions. Informants highlighted critical challenges that exist in collecting anemia, anthropometry, and infant and young child feeding data in large surveys while also offering solutions to strengthen data quality.
The DHS Program is committed to continuous quality improvement and is uniquely positioned to implement new data quality measures. Yet, the report is not only intended to inform operations at The DHS Program. The lessons learned are applicable to wider audiences involved in the collection and use of nutrition data throughout the world. Strengthening the quality of nutrition data will lead to improved data-driven nutrition actions.

This post is part of a series commemorating 30 years of The DHS Program.
By Fred Arnold
Historically, India has suffered through devastating periods of famine, but due to the Green Revolution, improved food storage and distribution, and other factors, famine has been all but eradicated in the country. However, malnutrition continues to threaten the health of India’s population.
The National Family Health Surveys (as DHS surveys are known in India) have been documenting the nutrition situation in India since 1992 (by measuring the height, weight, and anemia status of children and adults, and by assessing infant and young child feeding practices). These surveys have brought to the nation’s consciousness the excessively high levels of stunting, wasting, underweight, and anemia that young children in India continue to suffer from. The most recent NFHS survey (NFHS-3) found that nearly half of children under five are stunted, 43% are underweight, 20% are wasted, and 7 out of every 10 children are anemic. Stunting among children was as high as 60% in the lowest wealth quintile, but was still considerable (25%) even in the highest wealth quintile. These findings were widely reported in the media, were agonized over by international organizations and NGOs, and were prominently discussed at the highest levels of government. In two national addresses, Prime Minister Manmohan Singh revealed that he had seen the results of the National Family Health Survey, and he declared the poor nutrition of India’s children to be “a national shame.” He immediately responded by writing a letter to the Chief Ministers of every state in the country, ordering them to take up the fight against malnutrition “on a war footing” and to report back to him every quarter on the progress that had been made.
Based on the NFHS-3 findings, that same year I wrote a paper on the nutrition landscape in India, which was published in Demography India and presented as the keynote speech at the Annual Meeting of the Indian Association for the Study of Population. That reached yet another important constituency that joined the national dialogue on nutrition.
Another aspect of nutrition that was documented in that paper was the emerging dual burden of simultaneous undernutrition and overnutrition among Indian adults. About one-third of women and men were abnormally thin and about 1 in 8 were overweight or obese, meaning that only about half of adults had a normal nutritional status. The figures are even more alarming in certain segments of the population. Thirty to forty percent of women were overweight or obese in some of India’s largest cities, and even in urban slums, 20-30% of women fell in that category.
Since NFHS-3, there have been encouraging signs of improvements in nutrition in some places, but discouraging signs of stagnation or deterioration in others. The results of the NFHS-4 survey, which is just about to go into the field, are eagerly awaited to provide more definitive information on the current nutrition situation. And when the next chapter in India’s nutrition history is written, NFHS will be there to monitor trends and provide vital information to guide informed policymaking and program planning.
Fred Arnold, Technical Deputy Director—Dr. Arnold is responsible for setting the overall technical direction for The DHS Program and coordinating the design of DHS questionnaires. He has coordinated technical assistance to four large-scale National Family Health Surveys in India, which have included interviews with more than one million women and men, working with more than 40 organizations (government ministries, funding agencies, international organizations, and implementing agencies) in the conduct of the surveys. He has been involved in the design and implementation of surveys in 15 additional countries. Dr. Arnold has a Ph.D. in economics/demography from the University of Michigan. He has authored more than 150 publications in areas such as malaria; HIV; maternal, newborn and child health; nutrition; son preference; international migration; and the value of children.
