Cross-sectional growth assessment of children in four refugee camps in Northern Greece

Prevalence of stunting among under-five children in refugee and internally displaced communities: a systematic review and meta-analysis

Background

A pooled estimate of stunting prevalence in refugee and internally displaced under-five children can help quantify the problem and focus on the nutritional needs of these marginalized groups. We aimed to assess the pooled prevalence of stunting in refugees and internally displaced under-five children from different parts of the globe.

Methods

In this systematic review and meta-analysis, seven databases (Cochrane, EBSCOHost, EMBASE, ProQuest, PubMed, Scopus, and Web of Science) along with "preprint servers" were searched systematically from the earliest available date to 14 February 2023. Refugee and internally displaced (IDP) under-five children were included, and study quality was assessed using "National Heart, Lung, and Blood Institute (NHLBI)" tools.

Results

A total of 776 abstracts (PubMed = 208, Scopus = 192, Cochrane = 1, Web of Science = 27, Embase = 8, EBSCOHost = 123, ProQuest = 5, Google Scholar = 209, and Preprints = 3) were retrieved, duplicates removed, and screened, among which 30 studies were found eligible for qualitative and quantitative synthesis. The pooled prevalence of stunting was 26% [95% confidence interval (CI): 21-31]. Heterogeneity was high (I2 = 99%, p < 0.01). A subgroup analysis of the type of study subjects revealed a pooled stunting prevalence of 37% (95% CI: 23-53) in internally displaced populations and 22% (95% CI: 18-28) among refugee children. Based on geographical distribution, the stunting was 32% (95% CI: 24-40) in the African region, 34% (95% CI: 24-46) in the South-East Asian region, and 14% (95% CI: 11-19) in Eastern Mediterranean region.

Conclusion

The stunting rate is more in the internally displaced population than the refugee population and more in the South-East Asian and African regions. Our recommendation is to conduct further research to evaluate the determinants of undernutrition among under-five children of refugees and internally displaced populations from different regions so that international organizations and responsible stakeholders of that region can take effective remedial actions.

Undernutrition among children living in refugee camps: a systematic review of prevalence

OBJECTIVES

This review aimed to provide an overview of the prevalence of undernutrition in children under 5 years old in refugee camps according to the different indicators. In addition, we aimed to evaluate the quality and quantity of relevant epidemiological data available.

DESIGN

We used a systematic review of prevalence study design to achieve the above aims. We sought eligible observational studies through database searching of OVID Medline, CAB Global Health, Scopus and PubMed; citation chasing; and grey literature searching.

SETTING

The setting of interest was refugee camps across the globe.

PARTICIPANTS

Participants in the studies included in the review were children under 5 years old.

PRIMARY AND SECONDARY OUTCOME MEASURES

Outcome measures of interest were the prevalence of wasting, global acute malnutrition, stunting and underweight.

RESULTS

The review included 33 cross-sectional studies in 86 sites and a total of 36 750 participants. Overall, the quality of the studies was moderate to high, but some reports lacked clarity around data collection or outcome definitions. The results showed a wide variation in prevalence estimates across the different indicators and between different refugee camps. The median prevalence estimates of global acute malnutrition based on weight-for-height z-score, stunting and underweight were 7.1%, 23.8% and 16.7%, respectively. Using weight-for-height z-score identified a higher prevalence of acute malnutrition than using mid-upper arm circumference in the majority of studies.

CONCLUSIONS

Acute malnutrition remains a public health problem in many refugee camps, but chronic malnutrition has a high prevalence in more locations. Research and policy must, therefore, focus not only on nutrition but also on the wider determinants of both acute and chronic undernutrition. The difference in prevalence of global acute malnutrition depending on the measure used has implications for screening and diagnosis.

Prevalence of Malnutrition among Syrian Refugee Children from Lebanon

Today, the situation of Syrian refugees is one of the world's worst humanitarian crises. To estimate the prevalence of malnutrition among pediatric populations of Syrian refugees, 176 Syrian refugee children, with stays of more than two years at three refugee camps (Zalhé, Deddeh, and Kfar Jouz) or from the town of Yohmor, Lebanon were authorized by their parents to participate in this study. The children were anthropometrically evaluated and height-for-age Z-score (HAZ), weight-for-age Z-score (WAZ), and weight-for-height (WHZ) Z-scores were obtained and compared with WHO standards. Furthermore, mid-upper arm circumference (MUAC) was analyzed for screening children 6-59 months old. According to the anthropometric measures, no child met the criteria for chronic, global, acute malnutrition (CGAM), severe acute malnutrition (SAM), or moderate acute malnutrition (MAM). In the total sample, 49.4% of participants were moderately thin, with girls presenting a higher prevalence of thinness than that of boys. Thus, the absence of high rates of malnutrition was verified despite the magnitude of the Syrian refugee's problem. The data provided by this study identify the need to carry out further research to assess anthropometric growth and nutritional status among long-staying refugee children in order to prevent any health issues that may arise in the future.

Nutritional and health status of adult Syrian refugees in the early years of asylum in Germany: a cross-sectional pilot study

BACKGROUND

Migration is usually accompanied by changes in the social, cultural, and religious environment, socioeconomic status, and housing conditions, all of which affect nutritional health. In a cross-sectional study, we assessed the dietary intake as well as nutritional and health situation in a population of Syrian refugees who have resided in Germany for at least six months up to four years since 2015. The primary aim of this pilot study was to evaluate the nutritional and health status in comparison to reference values.

METHODS

Between December 2018 and March 2020, 114 adult Syrian refugees were included in the study. The subjects filled out questionnaires on sociodemographic variables, exercise, and nutrition behavior (three-day nutrition record). After a fasting blood draw, the subjects were examined for anthropometric parameters (height, weight, body mass index, waist circumference, waist-hip ratio, and body composition via a bioelectrical impedance analyzer). Various blood markers including iron status, hematological parameters, Vitamin D status, lipid metabolism, glucose metabolism, and total homocysteine (tHcy) were measured.

RESULTS

About half of the participants (71 male, 43 female) had lived in Germany for less than three years. Over 60% of men and 30% of women were overweight (BMI 25-30 kg/m2) or obese (BMI > 30 kg/m2), while 79% of men and 74% of women observed an elevated body fat mass. The evaluation of the three-day nutrition records revealed an unfavorable supply situation for numerous critical nutrients. More than half of the women (53.5%) had depleted iron stores (serum ferritin < 15 µg/l). The 25-OH-Vitamin D blood levels showed a high prevalence of Vitamin D insufficiency (25-49.9 nmol/l: 38% of men and 21% of women) and deficiency (< 25 nmol/l: 44% of men and 70% of women). 83% of men and 67% of women showed tHcy levels in plasma > 10 nmol/l. Fasting insulin levels and the HOMA-IR index indicate a risk for insulin resistance. Hyperlipidemia was prevalent, especially in males with 24% showing hypertriglyceridemia (> 150 mg/dl) and LDL-hypercholesterolemia (> 130 mg/dl).

CONCLUSIONS

The nutritional and health status of the cohort of Syrian refugees in Germany examined in this study is unsatisfactory, and many of the investigated refugees are at risk for developing cardiovascular disease and type 2 diabetes mellitus. Further studies are required to investigate the nutritional and health situation of refugees. This is obligatory to find ways to avoid malnutrition with all its associated health, sociodemographic, and economic consequences.

Double burden of malnutrition among migrants and refugees in developed countries: A mixed-methods systematic review

Migrants and refugees living in high income countries (HICs) have an increased risk of developing non-communicable diseases (NCDs) due to malnutrition at different stages over their life course. This systematic review aims to examine the double burden of malnutrition (DBM) among migrants and refugees in developed countries. This review was informed by the standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines. Eligible studies were peer-reviewed observational studies that focused on the DBM in refugee or migrant populations; and were written in English with full texts available and accessible. A combination of keywords was used to search 8 electronic bibliographic databases including Ovid MEDLINE, EMBASE, PsycINFO, CINAHL, ProQuest, Scopus, PubMed, and web of science. There is a paucity of research into the DBM among migrants and refugees residing in HICs. Of a total of 2344 articles retrieved from eight databases, 5 studies met the inclusion criteria. All included studies showed the co-existence of some form of undernutrition and overnutrition within the same population. Overnutrition (overweight and obesity) in the studied populations ranged from 11.1% to 42% while undernutrition (stunting, wasting and underweight) ranged from 0.3% to 17%. Standard measures for anthropometry as determined by World Health Organization (WHO) were used for data collection in all included studies. A piloted form informed by the Cochrane Public Health Group Data Extraction and Assessment Template was used in the extraction of data from retrieved studies. Quality assessment of included studies was performed using the study assessment tools of the National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) and showed that all studies were of fair quality. Interventions that simultaneously target more than one form of malnutrition especially amongst migrant and refugee populations must be implemented for policy solutions to be effective. This review has been registered by the PROSPERO international prospective registry for systematic reviews, reference CRD42020192416.

The prevalence of stunting among children and adolescents living in the Middle East and North Africa region (MENA): A systematic review and meta-analysis

Background

Given the strategic importance of the MENA, the state of war and inequity in the region and its effect on malnutrition which leads to mortality and reduced economic development in this region, the current study purposed to examine the prevalence of stunting as an indicator of chronic malnutrition in the MENA region, with consideration given HDI, rural/urban area, and war-involved countries.

Methods

The electronic databases of PubMed, SCOPUS, Web of science, and Embase were systematically searched, and English-language articles published between January 1, 2009 and December 31, 2019 were included in this study. The POLIS (population, outcome, location, indicator, study design) criteria were used to perform the systematic review, and studies involving children 2 to 18 years of age were selected.

Results

Fifty-eight (n = 2 202 869) were included based on the study's inclusion criteria. The prevalence of stunting in children in the total MENA region was 22.0% (95% confidence interval (CI) = 20.4-23.6; I² = 99.92%, P < 0.0001). The studies included in the meta-analysis were analyzed by subgroups. The pooled prevalence of stunting in children aged 2-5 years old and children aged 6 and older was 25.7% and 16.5%, respectively. The pooled prevalence of stunting was 34.1% in rural and 12.4% in urban areas. The pooled prevalence of stunting according to HDI was 30.1%, 28.5%, 13.1%, in low, medium, and high HDI countries, respectively. Furthermore, the pooled prevalence of stunting according to war status was 28.5% in war-involved countries vs 20.6% in others.

Conclusions

High prevalence of malnutrition was seen based on stunting indicator in the meta-analysis study in the MENA region, and this issue became more pronounced when the data was divided into subgroups based on age, residential area, and HDI. Inequality regarding social, economic, and political factors leads to significant malnutrition in the mentioned region.

Body mass index and associated factors among refugees living in North Rhine-Westphalia, Germany: a cross-sectional study

Background

This study aims to determine: (i) information on overweight and obesity, represented by body mass index using measured anthropometric data, among refugees living in North Rhine-Westphalia, Germany, (ii) how body mass index changed throughout the migratory journey to Germany, and (iii) factors influencing body mass index.

Methods

The study utilizes data from the FlueGe health study, a cross-sectional study conducted by Bielefeld University. The data was collected between February and November 2018 in which participants were recruited in several cities in North Rhine-Westphalia (N = 326). We analyzed differences in body mass index before the escape, upon arrival, and since arrival as well as correlations between body mass index since arrival and explanatory variables using linear regression models.

Results

The overall prevalence of overweight and obesity before the escape (t0), upon arrival (t1) and since arrival (t2) were 55.2% (150/272), 45.6% (133/292) and 54.8% (171/312), respectively, with 16.2% (44/272), 12.0% (35/292) and 16.0% (50/312) being obese. There was a significant change between t0 and t1 (p < 0.001), and between t1 and t2 (p < 0.001), but no change over time (between t0 and t2, p = 0.713). Results from multivariate linear regression showed that high education, male sex, higher body mass index before the escape, Iranian or Iraqi nationality, and sobriety were the significant factors for body mass index since arrival. However, when focusing on those who have reported weight gain only, higher body mass index before the escape, male sex, and Iraqi nationality were the significant factors.

Conclusions

Overweight and obesity were common among refugees after settlement in Germany. In particular, sociodemographic factors were associated with a higher body mass index since arrival. Thus, it is important to develop and apply nutrition-related intervention programs for adult refugees that are culturally appropriate and tailored to education level and sex.

Nutritional Status of Syrian Refugees in Early Adolescence Living in Turkey

This study evaluated the nutritional status of Syrian refugees in the early adolescent period living in different vulnerable settings. Nutritional assessment of Syrian refugee adolescents is often neglected but essential for a healthy physical, pubertal and mental development. Growth parameters of Syrian refugee adolescents going to a public school in an urban area and in a temporary protection center (TPC) were recorded along with the Turkish adolescents. Stunting percentages were similar between the groups (p = 0.811). While the proportion of children with a BMI over 85th percentile were significantly higher among Syrian adolescents living in TPC, Turkish children have the highest percentage of underweight (p = 0.01). Both food insecurity and unhealthy weight gain continue to be major concerns for refugee adolescents after their resettlement to a host country. The findings suggest that nutritional assessment and intervention at early adolescence is critical for Syrian refugees depending on their living conditions.

Natural history of growth and anaemia in children with epidermolysis bullosa: a retrospective cohort study

BACKGROUND

Impaired growth and anaemia are major extracutaneous complications of epidermolysis bullosa (EB), but data on their development are lacking.

OBJECTIVES

To determine the clinical course of growth and anaemia in children with EB and clarify the impact of nutritional compromise, inflammation and genetic factors.

METHODS

A retrospective study was conducted of 200 children, 157 with recessive dystrophic EB (RDEB) and 43 with junctional EB (JEB)-generalized intermediate, followed at the main referral centre in Germany. Growth charts were calculated using the modified LMS method and were correlated with parameters of anaemia, nutrition, inflammation and the molecular defect in a linear model.

RESULTS

In our cohort of patients with RDEB, weight impairment started at 12-18 months old; by the age of 10 years, 50% showed wasting. The predicted median weight at age 20 years was 35·2 kg for men and 40·1 kg for women. In JEB, growth resembled that of healthy children. Anaemia was present from the second year of life onwards in RDEB and JEB. Low levels of haemoglobin, iron, vitamin D, zinc and albumin, high levels of C-reactive protein, and absence of collagen VII correlated significantly with low weight in RDEB. No correlation was observed in JEB.

CONCLUSIONS

The results highlight that nutritional compromise occurs early in children with RDEB and therefore may require interventions as of the first year or two of life. What's already known about this topic? Children with epidermolysis bullosa (EB) suffer from failure to thrive and anaemia as major extracutaneous complications. The course of growth and the development of anaemia in EB are poorly characterized. What does this study add? A molecularly well characterized cohort of 200 children with EB was followed with regard to anthropometrics, anaemia and inflammation. We demonstrate early onset of growth failure and anaemia, most pronounced in the subset of recessive dystrophic EB. Awareness of early growth delay and nutritional deficiencies will improve EB care in daily practice.
