RESUMO
Infant and young child feeding (IYCF) plays a crucial role in early childhood growth and development. This study summarizes recent IYCF practices in multiple refugee settings and compares them to those in the host countries. We analyzed 203 surveys conducted among refugees residing in 15 countries and 120 unique sites and assessed eight IYCF indicators available from those surveys. A total of 146 surveys were conducted in Eastern and Southern Africa (ESA) and 50 in Western and Central Africa (WCA) regions. The median prevalence across surveys of all four indicators describing intake of breast milk was relatively high: 96.6% for ever breastfed, 81.2% for initiation of breastfeeding within 1 h of birth, 76.9% for exclusive breastfeeding 0-5 months, and 75.0% for continued breastfeeding 12-23 months. The median prevalence of early initiation and exclusive breastfeeding was markedly higher in ESA than in WCA (85.0% vs. 37.5% and 83.5% vs. 56.1%, respectively). Conversely, the overall median prevalence of timely introduction of solid and semisolid foods and flesh food consumption was low: 51.8% and 16.1%, respectively. Flesh food consumption was higher in WCA than in ESA (27.4% vs. 11.6%). The median prevalence of mixed milk feeding at 0-5 months and bottle feeding was very low: 2.4% and 3.8%, respectively. Indicators describing breast milk intake were generally either similar or higher in refugees than in the host country populations, whereas the other indicators were generally higher in the host populations than in refugees. The low prevalence of timely introduction of solids and of flesh food consumption in refugees is concerning and requires substantial improvement.

BACKGROUND: Currently, there is a lack of clear guidance on hemoglobin (Hb) data quality parameters and plausible flagging ranges for population-representative surveys. There is a need to determine which properties of Hb data indicate lower data quality and increased measurement error and which represent intrinsic statistical properties of Hb distributions rather than quality problems. METHODS: We explored statistical characteristics of Hb distributions and plausible exclusion ranges in population-representative surveys of non-pregnant women of reproductive age (WRA) (15-49 years, n = 401 surveys) and children (6-59 months, n = 461 surveys) conducted in refugee settings by the United Nations High Commissioner for Refugees (UNHCR). Hb distribution characteristics [standard deviation (SD), skewness and kurtosis] were compared to those from Demographic and Health Surveys (DHS). RESULTS: Overall, 0.08% of child and 0.14% of WRA Hb values were outside of the previously proposed 4.0-18.0 g/dL plausible range. Surveys conducted in Uganda tended to have unusually high SD compared with surveys from other settings, possibly an indication of problematic measurement quality. We therefore used summary results on SD, skewness and kurtosis excluding surveys from Uganda when comparing with DHS results or proposing plausible ranges. Both WRA and child Hb distributions tended to be left-skewed and had excess positive kurtosis. Mean survey-level SD was greater, mean skewness more negative, and mean kurtosis more positive in WRA surveys compared to child surveys. All these findings were broadly similar to those from DHS surveys. Mean SD in DHS surveys was higher than that in our data for both children (1.48 vs. 1.34) and WRA (1.58 vs. 1.43). CONCLUSIONS: We observed several statistical characteristics of Hb distributions that may not necessarily be indicative of data quality problems and bear strong similarities with the characteristics found in DHS surveys. Hb distributions tended to be negatively skewed and positively kurtotic, and SD in many surveys exceeded 1.5 (previously proposed upper plausible range). Based on our empirical evidence, surveys with skewness above + 0.2 and kurtosis below -0.5 or Hb SD outside the range of 1.1-1.55 g/dL for children (6-59 mo) or 1.1-1.65 g/dL for non-pregnant WRA (15-49 y) may require further quality investigation.

Despite frequent use of mid-upper arm circumference (MUAC) to assess populations in humanitarian settings, no guidance exists about the ranges for excluding implausible extreme outliers (flags) from MUAC data and about the quality assessment of collected MUAC data. We analysed 701 population-representative anthropometric surveys in children aged 6-59 months from 40 countries conducted between 2011 and 2019. We explored characteristics of flags as well as changes in survey-level MUAC-for-age z-score (MUACZ) and MUAC means, SD and percentage of flags based on three flagging approaches: ±3 and ±4 MUACZ z-scores from observed MUACZ survey mean and a fixed interval 100-200 mm of MUAC. Both ±4 and 100-200 flagging approaches identified as flags approximately 0.15% of records; about 60% of all surveys had no flags and less than 1% of surveys had >2% of flags. The ±3 approach flagged 0.6% records in the data set and 3% of surveys had >2% of flags. Plausible ranges (defined as 2.5th and 97.5th percentiles) for SD of MUACZ and MUAC were 0.8-1.2 and 10.5-14.4 mm, respectively. Survey-level SDs of MUAC and MUACZ were highly correlated (r = 0.68). The average SD of MUACZ was 0.96 using the ±4 flagging approach and 0.94 with ±3 approach. Defining outliers in MUAC data based on the MUACZ approach is feasible and adjusts for different probability of extreme values based on age and nutrition status of surveyed population. In assessments where age is not recorded and therefore MUACZ cannot be generated, using 100-200 mm range for flag exclusion could be a feasible solution.

BACKGROUND: The United States has admitted over 80,000 Special Immigrant Visa holders (SIVH), which include children. Despite the increase in the proportion of SIVH admissions to the US over recent years, little is known about health conditions in SIV children. We report the frequency of selected diseases identified overseas and assess differences in selected conditions between SIV children from Iraq and Afghanistan. METHODS AND FINDINGS: We analyzed 15,729 overseas medical exam data in Centers for Disease Control and Prevention's Electronic Disease Notification system (EDN) for children less than 18 years of age from Iraq (29.1%) and Afghanistan (70.9%) who were admitted to the US from April 2009 through December 2017 in a cross-sectional analysis. Variables included age, sex, native language, measured height and weight, and results of the overseas medical examination. From our analysis, less than 1% of SIV children (Iraqi: 0.1%; Afghan: 0.12%) were reported to have abnormal tuberculosis test findings, less than 1% (Iraqi: 0.3%; Afghan: 0.7%) had hearing abnormalities, and about 4% (Iraqi: 6.0% Afghan: 2.9%) had vision abnormalities, with a greater prevalence of vision abnormalities noted in Iraqis (OR: 1.9, 95% CI 1.6-2.2, p <0.001). Seizure disorders were noted in 46 (0.3%) children, with Iraqis more likely to have a seizure disorder (OR: 7.6, 95% CI 3.8-15.0, p < 0.001). On average, children from Afghanistan had a lower mean height-for-age z-score (Iraqi: -0.28; Afghan: -0.68). Only the data quality assessment for height for age for children ≥5 years fell within WHO recommendations. Limitations included the inability to obtain all SIVH records and self-reported medical history of noncommunicable diseases. CONCLUSION: In this investigation, we found that less than 1% of SIV children were reported to have abnormal tuberculosis test findings and 4% of SIV children had reported vision abnormalities. Domestic providers caring for SIVH should follow the US Centers for Disease Control and Prevention (CDC) Guidelines for the US Domestic Medical Examination for Newly Arriving Refugees, including an evaluation for malnutrition. Measurement techniques and anthropometric equipment used in panel site clinics should be assessed, and additional training in measurement techniques should be considered. Future analyses could further explore the health of SIV children after resettlement in the US.

BACKGROUND: More than 700,000 ethnic Rohingya have crossed the border from Rakhine State, Myanmar to Cox's Bazar District, Bangladesh, following escalated violence by Myanmar security forces. The majority of these displaced Rohingya settled in informal sites on previously forested land, in areas without basic infrastructure or access to services. METHODS AND FINDINGS: Three cross-sectional population-representative cluster surveys were conducted, including all informal settlements of Rohingya refugees in the Ukhia and Teknaf Upazilas of Cox's Bazar District. The first survey was conducted during the acute phase of the humanitarian response (October-November 2017), and the second and third surveys were conducted 6 (April-May 2018) and 12 (October-November 2018) months later. Anthropometric indices (weight, height, mid-upper arm circumference [MUAC], oedema) and haemoglobin (Hb) were measured in children aged 6-59 months following standard procedures. Final samples for survey rounds 1, 2, and 3 (R1, R2, and R3) included 1,113, 628, and 683 children, respectively, of which approximately half were male (50.7%-53.5% per round) and a third were 6-23 months of age (32.4%-33.3% per round). Prevalence of global acute malnutrition (GAM) as assessed by weight for height in R2 (12.1%, 95% CI: 9.6-15.1) and R3 (11.0%, 95% CI: 8.4-14.2) represent a significant decline from the observed prevalence in R1 (19.4%, 95% CI: 16.8-22.3) (p < 0.001 for both comparisons). Overall, the prevalence of anaemia significantly declined (p < 0.001) between the first 2 rounds (47.9%, 95% CI: 44.1-51.7 and 32.3%, 95% CI: 27.8-37.1, respectively); prevalence increased significantly (p = 0.04) to 39.8% (95% CI, 34.1-45.4) during R3 but remained below R1 levels. Reported receipt of both fortified blended foods (12.8%) and micronutrient powders (10.3%) were low during R1 but increased significantly (p < 0.001 for both) within the first 6 months to 49.8% and 29.9%, respectively. Although findings demonstrate improvement in anthropometric indicators during a period in which nutrition programme coverage increased, causation cannot be determined from the cross-sectional design. CONCLUSIONS: These data document significant improvements in both acute and micronutrient malnutrition among Rohingya children in makeshift settlements. These declines coincide with a scaleup of services aimed at prevention and treatment of malnutrition. Ongoing activities to improve access to nutritional services may facilitate further reductions in malnutrition levels to sustained below-crisis levels.

OBJECTIVE: To determine current status, areas for improvement and effect of conflict on infant and young child feeding (IYCF) practices among internally displaced persons (IDP) in eastern Ukraine. DESIGN: Cross-sectional household survey, June 2015. SETTING: Kharkiv, Dnipropetrovsk and Zaporizhia oblasts (Ukrainian administrative divisions) bordering conflict area in Ukraine. SUBJECTS: Randomly selected IDP households with children aged <2 years registered with local non-governmental organizations. Questions based on the WHO IYCF assessment questionnaire were asked for 477 children. Mid-upper arm circumference was measured in 411 children aged 6-23 months. RESULTS: Exclusive breast-feeding prevalence for infants aged <6 months was 25·8 (95 % CI 15·8, 38·0) %. Percentage of mothers continuing breast-feeding when their child was aged 1 and 2 years was 53·5 (95 % CI 43·2, 63·6) % and 20·6 (95 % CI 11·5, 32·7) %, respectively. Bottle-feeding was common for children aged <2 years (68·1 %; 95 % CI 63·7, 72·3 %). Almost all infants aged 6-8 months received solid foods (98·6 %; 95 % CI 88·5, 99·9 %). Mothers who discontinued breast-feeding before their infant was 6 months old more often listed stress related to conflict as their primary reason for discontinuation (45·7 %) compared with mothers who discontinued breast-feeding when their child was aged 6-23 months (14·3 %; P<0·0001). CONCLUSIONS: To mitigate the effects of conflict and improve child health, humanitarian action is needed focused on helping mothers cope with stress related to conflict and displacement while supporting women to adhere to recommended IYCF practices if possible and providing appropriate support to women when adherence is not feasible.

Humanitarian emergencies, including complex emergencies associated with fragile states or areas of conflict, affect millions of persons worldwide. Such emergencies threaten global health security and have complicated but predictable effects on public health. The Centers for Disease Control and Prevention (CDC) Emergency Response and Recovery Branch (ERRB) (Division of Global Health Protection, Center for Global Health) contributes to public health emergency responses by providing epidemiologic support for humanitarian health interventions. To capture the extent of this emergency response work for the past decade, we conducted a retrospective review of ERRB's responses during 2007-2016. Responses were conducted across the world and in collaboration with national and international partners. Lessons from this work include the need to develop epidemiologic tools for use in resource-limited contexts, build local capacity for response and health systems recovery, and adapt responses to changing public health threats in fragile states. Through ERRB's multisector expertise and ability to respond quickly, CDC guides humanitarian response to protect emergency-affected populations.

BACKGROUND: Cluster surveys provide rapid but representative estimates of key nutrition indicators in humanitarian crises. For these surveys, an accurate estimate of the design effect is critical to calculate a sample size that achieves adequate precision with the minimum number of sampling units. This paper describes the variability in design effect for three key nutrition indicators measured in small-scale surveys and models the association of design effect with parameters hypothesized to explain this variability. METHODS: 380 small-scale surveys from 28 countries conducted between 2006 and 2013 were analyzed. We calculated prevalence and design effect of wasting, underweight, and stunting for each survey as well as standard deviations of the underlying continuous Z-score distribution. Mean cluster size, survey location and year were recorded. To describe design effects, median and interquartile ranges were examined. Generalized linear regression models were run to identify potential predictors of design effect. RESULTS: Median design effect was under 2.00 for all three indicators; for wasting, the median was 1.35, the lowest among the indicators. Multivariable linear regression models suggest significant, positive associations of design effect and mean cluster size for all three indicators, and with prevalence of wasting and underweight, but not stunting. Standard deviation was positively associated with design effect for wasting but negatively associated for stunting. Survey region was significant in all three models. CONCLUSIONS: This study supports the current field survey guidance recommending the use of 1.5 as a benchmark for design effect of wasting, but suggests this value may not be large enough for surveys with a primary objective of measuring stunting or underweight. The strong relationship between design effect and region in the models underscores the continued need to consider country- and locality-specific estimates when designing surveys. These models also provide empirical evidence of a positive relationship between design effect and both mean cluster size and prevalence, and introduces standard deviation of the underlying continuous variable (Z-scores) as a previously unexplored factor significantly associated with design effect. The magnitude and directionality of this association differed by indicator, underscoring the need for further investigation into the relationship between standard deviation and design effect.
RESUMO
In early April 2014, two South Sudanese refugees in the Gambella region of western Ethiopia experienced acute onset of jaundice, accompanied by fever. One patient was a pregnant woman aged 24 years evaluated at a routine prenatal clinic visit in Leitchour refugee camp. The second patient was a malnourished boy aged 1 year who resided in Tierkidi refugee camp. The boy died despite hospitalization. During the last 2 weeks of May, four more cases of acute jaundice syndrome (AJS), defined as yellow discoloration of the eyes, were detected in Leitchuor. By mid-June, an additional 50 AJS cases were reported across three large camps in the region, Kule, Leitchuor, and Tierkidi, with 45 (90%) of these cases reported in Leitchuor. Sera collected from a convenience sample of 21 AJS cases were sent to Addis Ababa and Nairobi for real-time polymerase chain reaction testing; 12 (57%) were positive for hepatitis E virus (HEV) RNA. By January 2015, a total of 1,117 suspected cases of hepatitis E meeting the case definition of AJS were reported among refugees in camps across Gambella.

As a result of armed civil conflict in South Sudan that started in mid-December of 2013, an estimated 1.1 million persons were internally displaced, and approximately 400,000 refugees fled South Sudan to neighboring countries (primarily to Ethiopia, Uganda, Sudan, and Kenya). Refugees from South Sudan arriving in Ethiopia are sheltered in three refugee camps located in Gambella region: Leitchuor, Kule, and Tierkidi. The camps were established during January-May 2014 and have estimated refugee populations of 47,000, 51,000, and 50,000, respectively. Reports from health clinics and humanitarian agencies providing assistance to refugees suggested poor nutritional status of arriving refugees and elevated mortality rates. To assess the nutritional status of refugee children aged 6-59 months and mortality rates (crude [all ages] and aged <5 years), the Administration for Refugee and Returnee Affairs (an Ethiopian government aid agency), the United Nations High Commissioner for Refugees, World Food Programme, and United Nations Children's Fund, in collaboration with CDC, conducted cross-sectional population-representative surveys in Leitchuor, Kule, and Tierkidi camps during June-July 2014. Anthropometric measurements in children were taken using standard procedures, and nutritional status was classified based on 2006 World Health Organization (WHO) growth standards. Hemoglobin was measured using HemoCue Hb 301. Anemia was diagnosed according to WHO thresholds. Retrospective mortality rates in Leitchuor and Kule were measured using a household census method.

As a result of civil war, an estimated 2.8 million refugees have fled Syria and reside in neighboring countries, mainly Lebanon, Turkey, Jordan, and Iraq. The largest Syrian refugee camp in the region is Zaatari camp in Jordan, with approximately 79,000 refugees; another estimated 500,000 Syrian refugees live in Jordanian cities, towns, and villages, mostly in the capital (Amman) and in four northern governorates (Irbid, Mafraq, Jarash, and Zarqa). Although all registered refugees in Jordan receive food vouchers from the World Food Programme (WFP) and vulnerable refugees receive cash assistance from the United Nations High Commissioner for Refugees (UNHCR) and nongovernmental organizations, the nutritional status of some refugees might be compromised because of dislocation, lack of income, and limited access to nutritious foods. To assess the nutritional status of Syrian refugees, UNHCR, WFP, the United Nations Children's Fund (UNICEF), Medair International (a nongovernmental organization), and CDC, in collaboration with the United Nations Population Fund and the World Health Organization (WHO), conducted cross-sectional, population-representative cluster surveys in Zaatari camp and among refugees residing in the host community. The surveys were conducted during April-May 2014 with the principal objective of assessing nutritional status of refugee children aged 6-59 months and nonpregnant women of reproductive age (15-49 years). Preliminary findings indicated a high prevalence of anemia in Zaatari camp among both children and women (48.4% and 44.8%, respectively). Nutrition policies aimed at ensuring optimal child and maternal micronutrient status and addressing the underlying risk factors for anemia are likely to result in improved health outcomes and a reduction in anemia.

Introduction: During emergencies, breastfeeding protects infants by providing essential nutrients, food security, comfort, and protection and is a priority lifesaving intervention. On February 24, 2022, the war in Ukraine escalated, creating a humanitarian catastrophe. The war has resulted in death, injuries, and mass internal displacement of over 5 million people. A further 8.2 million people have taken refuge in neighboring countries, including Poland. Among those impacted are infants and young children and their mothers. We conducted a study to explore the infant feeding challenges and needs of Ukrainian women affected by the war. Methods: We conducted a qualitative descriptive study involving in-depth interviews (IDIs) with 75 war-affected Ukrainian mothers who had at least one infant aged less than 12 months at the time of the interview. Eligible mothers were either (1) living as Ukrainian refugees in Poland, having crossed the border from Ukraine on or after February 24, 2022, when the war started (n = 30) or (2) living in Ukraine as internally displaced persons or as residents in the community (n = 45). All interviews were audio-recorded (either transcribed or had responses summarized as expanded notes) and analyzed using qualitative thematic analysis using a two-step rapid analysis process. Results: Participants in Ukraine who wanted to initiate breastfeeding right after birth faced opposition from healthcare workers at maternity hospitals. Ukrainian refugees who gave birth in Poland faced language barriers when seeking breastfeeding support. Half of the participants in Ukraine received commercial milk formula (CMF) donations even if they said they did not need them. Most respondents stated that breastfeeding information and support were urgently needed. Conclusion: Our data suggests that healthcare workers in Ukrainian maternity hospitals require additional training and motivation on delivering breastfeeding support. In addition, lactation consultants in maternity ward are needed in Ukraine, and interpretation support is needed for refugees to overcome language barriers. There is a need to control the indiscriminate donations of commercial milk formula and to ensure that complementary foods and commercial milk formula are available to those that need it. This study confirms the need for actions to ensure infant and young child feeding (IYCF) support is provided during emergencies.

BACKGROUND: The PROBIT methodology was presented in the 1995 World Health Organization Technical Report on Anthropometry as an alternative to the standard prevalence based method of measuring malnutrition in children. Theoretically the PROBIT method will always give a smaller standard error than the standard prevalence method in measuring malnutrition. A recent article by Dale et al. assessed the PROBIT method for measuring global acute malnutrition measure and found that the method was biased and the precision was superior only for sample sizes less than 150 when compared to the standard method. In a manner similar to Dale, our study further investigated the bias and precision of the PROBIT method for different sample sizes using simulated populations. RESULTS: The PROBIT method showed bias for each of the ten simulated populations, but the direction and magnitude of the average bias was changed depending on the simulated population. For a given simulated population, the average bias was relatively constant for all sample sizes drawn. The 95% half-width confidence interval was lower for the PROBIT method than the standard prevalence method regardless of the sample size or simulated population. The absolute difference in the confidence limits showed the most gains for the PROBIT method for the smaller samples sizes, but the ratio of confidence intervals was relatively constant across all sample sizes. CONCLUSIONS: The PROBIT method will provide gains in precision regardless of the sample size, but the method may be biased. The direction and magnitude of the bias depends on the population it is drawn from.

The efficacy of micronutrient powders (MNP) in the treatment of anemia in moderately anemic children aged 6-24 mo has been clearly demonstrated. The evidence of the effectiveness of MNP in large-scale programs, however, is scarce. This article describes the program experience and findings of large-scale MNP distribution in refugee camps and in an emergency context in Bangladesh, Nepal, and Kenya. The MNP contained 15-16 micronutrients as per the WHO/World Food Programme/UNICEF joint statement, whereas the iron content was reduced to 2.5 mg from NaFeEDTA in a malaria-endemic area in Kenya. Hundreds of thousands of children aged 6-59 mo and pregnant and lactating women were targeted to consume MNP either daily or every other day over an extended period of time. Extensive social marketing campaigns were undertaken to promote regular use of the product. A number of studies were embedded in the programs to assess the impact of MNP on the nutritional status of target beneficiaries. Some improvements in anemia prevalence estimates were observed in particular subgroups, but other results did not show significant improvements. A significant decrease in the prevalence of stunting was observed in Nepal and Kenya but not in Bangladesh. Diarrhea episodes decreased significantly among children receiving MNP in Nepal. A key challenge is to ensure high MNP acceptance and adherence among beneficiaries. Investigation of non-nutritional causes of anemia is warranted in settings with high compliance but no improvement in hemoglobin status. Further investigation into the most appropriate manner to use MNP in malaria endemic settings is warranted.

The technical discourse on nutrition surveillance started decades ago, and the first technical guidelines were proposed in mid-1970s. In spite of this long history, little evidence and consensus exists on the best methods for conducting nutrition surveillance, and on the validity of data produced by these approaches. Multiple nutrition surveillance systems exist in humanitarian settings; however, the validity and usefulness of data produced by these systems are often questionable. In this paper, we outline and define five major methodological approaches to collecting child anthropometric data through surveillance: repeated surveys, community-based sentinel sites, mass screenings, admission data from feeding centers, and data from health clinics. We discuss outstanding methodological and practical challenges with direct implications for quality, validity, and interpretability of collected data and highlight comparative advantages and disadvantages of different methods. We also propose ways forward to building a better evidence base by documenting the strengths and limitations of different approaches, with the eventual goal of achieving consensus on the best ways to collect anthropometric data through surveillance.

BACKGROUND: Following more than a decade of civil conflict, Nepal is among the countries affected by landmines, victim-activated improvised explosive devices (IED) and other explosive remnants of war (ERW). OBJECTIVES: To assess the magnitude of injuries due to landmines, victim-activated IED and other ERW in Nepal and to describe epidemiological patterns and risk factors for these events. METHODS: Analysis of surveillance data on civilian injuries due to landmines, victim-activated IED and other ERW between July 2006 and June 2010. Data were collected through active community-based prospective surveillance. RESULTS: Of 307 total casualties, 94 (31%) were female and 169 (55%) were children under 18 years of age. The case-fatality ratio was 14%. The highest number of casualties was in the age group 10-14 years. 233 (76%) injuries were caused by victim-activated IED, 13 (4%) by landmines and 44 (14%) by other ERW. Two types of IED, sutali and socket bombs, caused the majority of injuries (28% and 31%, respectively). 117 (38%) of all injuries occurred in victims' homes and 152 (50%) occurred while victims were tampering with explosive devices. CONCLUSIONS: Substantial numbers of civilians, including women and children, were injured and killed following implementation of the Comprehensive Peace Agreement in 2006. The government of Nepal and humanitarian organisations should continue their efforts to reach communities at highest risk through targeted interventions and nationwide media campaigns to convey the risks of tampering with explosive devices or suspicious objects.

BACKGROUND: Anemia remains a significant public health problem in refugee settings. Home fortification with micronutrient powders has been proposed as a feasible option to alleviate micronutrient deficiencies; its efficacy in reducing anemia in children aged 6 to 24 months has been demonstrated in several trials. OBJECTIVE: To evaluate the effectiveness of a large-scale micronutrient powder distribution program in reducing anemia prevalence and promoting growth in refugee children aged 6 to 59 months. METHODS: Four representative cross-sectional surveys were conducted 13 months before and 7, 14, and 26 months after initiation of the supplementation program. Data collected on children aged 6 to 59 months included hemoglobin concentration, anthropometric indicators, morbidity, feeding practices, and information on the micronutrient distribution program. The study had a pre-post design with no control group. RESULTS: The overall prevalence of anemia in children did not change significantly between baseline (43.3%) and endpoint (40.2%). The prevalence of moderate anemia decreased over the same period from 18.9% to 14.4% (p < .05). The levels of severe anemia were negligible (< 1%) in all surveys. The prevalence of stunting decreased significantly from 39.2% at baseline to 23.4% at endpoint (p < .001), a relative decrease of40%. Reported coverage, use, and acceptance of micronutrient supplements remained consistently high throughout the study. CONCLUSIONS: In the absence of a control group, changes in key outcomes should be interpreted with caution. The minor effect on hemoglobin status requires further investigation of underlying causes of anemia in this population. The large positive effect on linear growth may be a significant benefit of supplementation if confirmed by future studies.

INTRODUCTION AND OBJECTIVE: The World Food Programme and the Office of the United Nations High Commissioner for Refugees organized a meeting of experts to discuss evaluation of micronutrient interventions under special circumstances, such as emergency and refugee situations. RESULTS: Multimicronutrient interventions for groups with higher needs may include home fortification products for young children or supplements for pregnant and lactating women. The choice of preparation should be guided by target group needs, evidence of efficacy of a product or its compounds, acceptability, and cost-effectiveness. Different designs can be used to assess whether an intervention has the desired impact. First, program implementation and adherence must be ascertained. Then, impact on micronutrient status can be assessed, but design options are often limited by logistic challenges, available budget, security issues, and ethical and practical issues regarding nonintervention or placebo groups. Under these conditions, a plausibility design using pre- and postintervention cross-sectional surveys, a prospective cohort study, or a step-wedge design, which enrolls groups as they start receiving the intervention, should be considered. Post hoc comparison of groups with different adherence levels may also be useful. Hemoglobin is often selected as an impact indicator because it is easily measured and tends to respond to change in micronutrient status, especially iron. However, it is not a very specific indicator of micronutrient status, because it is also influenced by inflammation, parasitic infestation, physiological status (age, pregnancy), altitude, and disorders such as thalassemia and sickle cell disease. CONCLUSION: Given the constraints described above, replicability of impact in different contexts is key to the validation of micronutrient interventions.
