Association between Child Nutritional Anthropometric Indices and Iron Deficiencies among Children Aged 6-59 Months in Nepal

Developmental impairment remains an important public health problem among children in many developing countries, including Nepal. Iron deficiency in children may affect development and lead to anaemia. This study on 1702 children aged 6-59 months aimed to assess the association between nutritional anthropometric indices and iron deficiencies. Data for this study were extracted from the 2016 Nepal National Micronutrient Status Survey. Three nutritional anthropometric indices (stunting, wasting and underweight) and their association with anaemia and iron deficiencies (ferritin and sTfR biomarkers) were assessed by conducting multivariate statistical analyses. The prevalence of stunting, wasting and underweight among children aged 6-59 months was 35.6%, 11.7% and 29.0%, respectively. Most of the children were not stunted (64.4%), not wasted (71.0%) and not underweight (88.3%). Belonging to castes other than the Janajati, Dalit and Brahmin castes increased the odds of anaemia and iron deficiency (ferritin biomarker). Children in the age group 6-23 months were significantly at higher odds of having anaemia and iron deficiency (ferritin and sTfR biomarkers). Stunting significantly increased the odds of anaemia [adjusted odds ratio (OR): 1.55; 95% confidence interval (CI): (1.11, 2.17)], iron deficiency (ferritin biomarker [OR: 1.56; 95% CI: (1.16, 2.08)] and sTfR biomarker [OR: 1.60; 95% CI: (1.18, 2.15)]). Further, underweight significantly increased the odds of anaemia [OR: 1.69; 95% CI: (1.12, 2.54)] and iron deficiency (sTfR biomarker [OR: 1.48; 95% CI: (1.14, 1.93)]). Interventions to minimise the occurrence of anaemia and iron deficiencies among children in Nepal should focus on providing appropriate healthcare services that would reduce the burden of stunting and underweight.

The influence of adolescents' nutrition knowledge and school food environment on adolescents' dietary behaviors in urban Ethiopia: A qualitative study

Adolescence is a critical period of physical, cognitive, and social development that needs to be supported with healthy diets. Dietary behaviours of adolescents can be shaped by their nutrition-literacy and their interaction with parents and peers as well as their school food environment. Therefore, the present study aimed to assess factors that influence dietary behaviours of adolescents in urban Ethiopia. Sex-disaggregated, focused group discussions (n = 70) were conducted in 36 private and government schools (n = 12/city) among adolescents (n = 432) 15-19 years of age in Addis Ababa, Bahir Dar, and Dire Dawa. Photovoice was applied in a subgroup of participants (n = 216) to gain further insights into adolescents' perception of their school food environment. Key informant interviews were conducted among school principals (n = 36). Adolescents had a relatively good nutrition knowledge and recognised the importance of diverse diets, but misperceptions also existed. They identified fruit and vegetables as healthy foods, but their consumption was deterred by food safety concerns. The adolescents identified foods high in salt, fat, and sugar, including processed/packaged foods as unhealthy, but still consumed them frequently due to their taste, affordability, availability and accessibility in and around schools. Both undernutrition and overweight/obesity were linked to social exclusion and bullying in school. Effective behavioural change communication is required to address common misperceptions. School nutrition programs should integrate water, sanitation and hygiene programs to ensure food safety. Regulations promoting healthy eating while discouraging unhealthy dietary behaviours are vital. Interventions to make nutrient-dense and healthy foods available, accessible, and affordable are urgently needed to improve the nutrition and health outcome of adolescents.

Ethiopia National Food and Nutrition Survey to inform the Ethiopian National Food and Nutrition Strategy: a study protocol

INTRODUCTION

Ethiopia has made significant progress in reducing malnutrition in the past two decades. Despite such improvements, a substantial segment of the country's population remains chronically undernourished and suffers from micronutrient deficiencies and from increasing diet-related non-communicable diseases such as diabetes, hypertension and cancer. This survey aims to assess anthropometric status, dietary intake and micronutrient status of Ethiopian children, women and adolescent girls. The study will also assess coverage of direct and indirect nutrition-related interventions and map agricultural soil nutrients. The survey will serve as a baseline for the recently developed Ethiopian Food System Transformation Plan and will inform the implementation of the National Food and Nutrition Strategy.

METHODS AND ANALYSIS

As a population-based, cross-sectional survey, the study will collect data from the 10 regions and 2 city administrations of Ethiopia. The study population will be women of reproductive age, children aged 0-59 months, school-aged children and adolescent girls. A total of 16 596 households will be surveyed, allowing the generation of national and regional estimates. A two-stage stratified cluster sampling procedure will be used to select households. In the first stage, 639 enumeration areas (EAs) will be selected using probability-proportional-to-size allocation. In the second stage, 26 eligible households will be selected within each EA using systematic random selection. Primary outcomes include coverage of direct and indirect nutrition interventions, infant and young child feeding (IYCF) practices, food insecurity, dietary intakes, mental health, anthropometric status, micronutrient status and soil nutrient status.

ETHICS AND DISSEMINATION

The protocol was fully reviewed and approved by the Institutional Review Board of the Ethiopian Public Health Institute (protocol no: EPHI-IRB-317-2020). The study is based on voluntary participation and written informed consent is required from study participants. The findings will be disseminated via forums and conferences and will be submitted for publication in peer-reviewed journals.

Co-coverage of reproductive, maternal, newborn and child health interventions shows wide inequalities and is associated with child nutritional outcomes in Ethiopia (2005-2019)

The health system is the primary vehicle for the delivery of nutrition-specific interventions that aim to reduce maternal and child malnutrition. The integration of nutrition interventions into existing health interventions is promising, but to ensure that no one is left behind requires that access to essential health services is equitably distributed. This study aims to assess trends and socioeconomic inequalities in coverage of reproductive, maternal, newborn and child health (RMNCH) and assess its association with child nutritional outcomes in Ethiopia. Using the Ethiopian Demographic and Health Survey (2005, 2011, 2016, and 2019), we estimated the coverage of RMNCH interventions in Ethiopia using the co-coverage index, which is a count of the number of interventions accessed. We assessed the trend and inequalities in co-coverage and evaluated its association with child nutritional outcomes like stunting, wasting, and minimum dietary diversity (MDD). The national co-coverage index has shown a significant increase over the 2005-2019 period. However, all of the RMNCH interventions constituting the co-coverage index showed a pro-rich and pro-urban distribution (p < 0.05). The highest inequality, based on the slope index of inequality (SII), was observed for skilled assistance during delivery (SII: 80.4%), followed by access to an improved source of drinking water (SII: 62.6%), and antenatal care visits (SII: 55.5%). The low coverage in RMNCH and the observed inequality were associated with stunting, wasting, and MDD. Reducing socioeconomic inequality in RMNCH is key to achieve the health, nutrition and equity-related goals of the Sustainable Development Goals.

Pathways and approaches for scaling-up of community-based management of acute malnutrition programs through the lens of complex adaptive systems in South Sudan

Background

Funds for community-based management of acute malnutrition (CMAM) programs are short-term in nature. CMAM programs are implemented in countries with weak policies and health systems and are primarily funded by donors. Beyond operational expansion, their institutionalisation and alignment with governments’ priorities are poorly documented. The study aimed to identify pathway opportunities and approaches for horizontal and vertical scaling up of CMAM programs in South Sudan.

Methods

The study was conducted in South Sudan between August and September 2021 using an online qualitative survey with 31 respondents from policy and implementing organisations. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework guided the study’s design. It was self-administered through the Qualtrics platform. We used Qualitative Content Analysis supported by the Nvivo coding process. A deductive a priori template of codes approach was complemented by a data-driven inductive approach to develop the second level of interpretive understanding.

Results

Findings from the study demonstrate that the emphasis of CMAM programs was horizontal scaling up, characterised by geographic distribution and coverage as well as operational expansion. Main challenges have included unsustainable funding models, the inadequacy of existing infrastructure, high operational costs, cultural beliefs, and access-related barriers. Factor impacting access to CMAM programs have been geographical terrains, safety, and security concerns. Vertical scaling up, which emphasises institutional and ownership strengthening through a sound policy, regulatory, and fiscal environment, received relatively little attention. Nutrition supplies are not part of the government’s essential drug list and there is limited or no budgetary allocation for nutrition programs by the government in national budgets and fiscal strategies. Factors constraining vertical scalability have included weak government systems and capacity, a lack of advocacy and lobbying opportunities, and an apparent lack of exits strategies.

Conclusion

Addressing the scalability problems of CMAM programs in South Sudan demands a delicate balancing act that prioritises both horizontal and vertical scalability. Government and political leadership that harness multidisciplinary and multi-sectoral coordination are required. There is a need to increase policy commitment to malnutrition and associated budgetary allocation, emphasise local resource mobilisation, and ensure financial sustainability of integrating CMAM programs into the existing health and welfare system.

Child feeding practices in rural Ethiopia show increasing consumption of unhealthy foods

The quality of complementary feeding can have both short- and long-term health impacts by delaying or promoting child growth and establishing taste preferences and feeding behaviours. We aimed to assess the healthy and unhealthy feeding practices of infants and young children in rural Ethiopia. We conducted two rounds of surveys in December 2017/18 in Habru district, North Wello, rural Ethiopia among caregivers of infants and young children (N = 574). We characterised the consumption of infants and young children using non-quantitative 24 h recall and the World Health Organization infant and young child feeding indicators. Sociodemographic characteristics, anthropometry and haemoglobin concentrations were assessed. Breastfeeding was a norm as 82% and 67% were breastfed in the first and second rounds. Between the two rounds, dietary diversity increased from 5% to 17% (p < 0.05), but more pronounced increases were observed in the consumption of ultra-processed food (UPFs). Up to one-in-five (22%) of the children consumed UFPs. With an average of only three food groups consumed, the consumption of nutrient-dense foods like animal source foods, fruits and vegetables was very low particularly among younger children. UPFs are an additional risk factor that contributes to poor quality diets. Behavioural Change Communication interventions, including those in rural areas, should explicitly discourage the consumption of UPFs. Future studies should aim to quantify the amount of UPFs consumed and evaluate how this is associated with diet adequacy and nutritional outcomes.

Drivers of change in weight-for-height among children under 5 years of age in Ethiopia: Risk factors and data gaps to identify risk factors

The prevention of wasting should be a public health priority as the global burden of acute malnutrition is still high. Gaps still exist in our understanding of context-specific risk factors and interventions that can be implemented to prevent acute malnutrition. We used data from the four rounds of the Ethiopia Demographic and Health Survey (2000-2016) to identify risk factors that have contributed to the change in weight-for-height z-score (WHZ) among children under 5 years of age. We performed a pooled linear regression analysis followed by a decomposition analysis to identify relevant risk factors and their relative contribution to the change in WHZ. Modest improvements in WHZ were seen between 2000 and 2016. The sharpest decrease in mean WHZ occurred from birth to 6 months of age. Perceived low weight at birth and recent diarrhoea predicted a decline in WHZ among children aged 0-5, 6-23 and 23-59 months. Less than 50% of the change in WHZ was accounted for by the change in risk factors included in our regression decomposition analysis. This finding highlights data gaps to identify context-specific wasting risk factors. The decline in the prevalence of recent diarrhoea (15% of the improvement), decline in low birth size (7%-9%), and an increase in wealth (15%-30%) were the main risk factors that accounted for the explained change in WHZ. Our findings emphasize the importance of interventions to reduce low birthweight, diarrhoea and interventions that address income inequities to prevent acute malnutrition.

Magnitude, trends and drivers of the coexistence of maternal overweight/obesity and childhood undernutrition in Ethiopia: Evidence from Demographic and Health Surveys (2005-2016)

Ethiopia faces a rising problem of overweight and obesity alongside a high prevalence of undernutrition; a double burden of malnutrition (DBM). This study aimed to quantify the magnitude and trends of household-level DBM-defined as the coexistence of maternal overweight/obesity and child undernutrition (i.e., stunting or anaemia)-in Ethiopia between 2005, 2011 and 2016 and understand the potential drivers influencing DBM and the change in DBM over time. Data come from the Ethiopian Demographic and Health Surveys. National and regional prevalence estimates of the DBM were calculated (n = 13,107). Equiplots were produced to display inequalities in the distribution of DBM. Factors associated with DBM were explored using pooled multivariable logistic regression analyses for 2005, 2011 and 2016 (n = 9358). These were also included in a logistic regression decomposition analysis to understand their contribution to the change in DBM between 2005 and 2016 (n = 5285). The prevalence of household-level DBM at the national level was low, with a modest increase from 2.4% in 2005% to 3.5% in 2016. This masks important within-country variability, with substantially higher prevalence in Addis Ababa (22.8%). Factors positively associated with DBM were maternal age (odds ratio [OR] = 1.04 [1.02, 1.06]), urban residence (OR = 3.12 [2.24, 4.36]), wealth (OR = 1.14 [1.06, 1.24]) and the number of children <5 in the household (OR = 1.30 [1.12, 1.49]). Overall, 70.5% of the increase in DBM between 2005 and 2016 was attributed to increased wealth, urban residence and region. Double-duty actions that address multiple forms of malnutrition are urgently needed in urban settings.

Complementary feeding and food-group level inequality among Ethiopian children 6-23 months of age (2011-2019)

Ensuring diet quality in the first 2 years of life is critical to preventing malnutrition and instilling healthy food preferences. Children's diet quality has changed little over time and inequalities by socioeconomic status, rural-urban residence, but also by food group may exist. Using data from the 2011, 2016 and 2019 demographic and health surveys (DHS), we estimated the prevalence and inequalities in the minimum diet diversity (MDD), minimum meal frequency (MMF) and minimum acceptable diet (MAD). We further assessed food group-level inequities. In 2019, only 13.5% of children 6-23 months of age met the MDD, 55% met the MMF and only 11% met the MAD indicator. Absolute and relative measures of inequality were calculated. Modest increases in MDD, MMF and MAD were observed over the past decade (2011-2019). These modest improvements were concentrated in limited geographical areas, among children in wealthier households, and urban residents. Unhealthy practices such as bottle-feeding and zero fruit and vegetables have been increasing; whereas, inequities in the consumption of nutrient-dense foods have widened. Nevertheless, children from the wealthiest quintile also failed to meet the MDD. Multisectoral efforts that span from diversifying the food supply, regulating the marketing of unhealthy foods, and promoting minimal processing of perishables (i.e., to extend shelf-life) are needed. Context-adapted behavioural change communication along with nutrition-sensitive social protection schemes are also needed to equitably improve the diet quality of children in Ethiopia.

Evaluating the coverage and quality of nutrition programs via a bottom-up approach: A secondary analysis of real-time data from an end-user monitoring system in Ethiopia

Over the last two decades, great efforts and investments have been made in Ethiopia to ensure that all children have equal access to nutrition services in health facilities. While quality health systems are a prerequisite for quality nutrition services, little attention has been given to the evaluation of the supply and delivery services. The purpose of the study was to evaluate the coverage and quality of the nutrition-specific interventions delivered through the health system. Using an end-user monitoring (EUM) system, we monitored the delivery of nutrition-specific interventions in 500 districts, having 2514 health facilities distributed throughout Ethiopia. Data were collected through third-party monitors between August 2020 and 2021. Roughly 90% of health facilities were performing severe acute malnutrition management in line with the national guideline/protocol, and 2/3 of the assessed facilities were delivering iron and folic acid, vitamin A supplementation and deworming. A third of the messages on AMIYCN were retained by beneficiaries. Warehouse conditions were good in 64.3% of the facilities, but only 22% had good recording practices and about half had problems related to the quality and availability of nutrition supplies. Most beneficiaries were satisfied with the nutrition supplies and service delivered at the health facility level. This study also suggests the relevance of an EUM system to assess the quality of nutrition service delivery and its related supply management, as well as to improve the implementation of nutrition interventions as a decision-making tool.

Estimating the number of deaths averted from 2008 to 2020 within the Ethiopian CMAM programme

The management of wasting in Ethiopia is heavily reliant on the Community-based Management of Acute Malnutrition (CMAM) programme that has been implemented in more than 18,000 service delivery points scattered across the country. Despite the full-scale implementation of the CMAM, the number of child death averted, and the cost per child death averted remains unknown. This study aimed to estimate the cost and the number of child death averted by the CMAM programme between 2008 and 2020. Using data from routine monitoring of the CMAM programme, we estimated the excess mortality averted by the programme and estimated the cost per averted child death based on supply and labour. Over the past 13 years between 2008 and 2020, 3.6 million children under 5 years were admitted to the Ethiopian CMAM programme. The yearly average admission of 317,228 was achieved since 2011. On average, ~34,000 child deaths were averted yearly. The CMAM programme was estimated to have saved 437,654 (95% confidence interval [CI]: 320,161; 469,932) child deaths between 2008 and 2020, approximately 12% of the admitted cases. The average cost of the programme per adverted death was estimated at US$762/child death averted (95% CI = 639; 1001). The CMAM programme in Ethiopia is cost-effective and has continued to avert a significant number of child death. Given the high short- and long-term economic and health consequences of child wasting, concerted multi-sectoral efforts are needed to accelerate progress not only in its treatment but also in its prevention.

Elucidating the sustained decline in under-three child linear growth faltering in Nepal, 1996-2016

Childhood linear growth faltering remains a major public health concern in Nepal. Nevertheless, over the past 20 years, Nepal sustained one of the most rapid reductions in the prevalence of stunting worldwide. First, our study analysed the trends in height-for-age z-score (HAZ), stunting prevalence, and available nutrition-sensitive and nutrition-specific determinants of linear growth faltering in under-three children across Nepal's Family Health Survey 1996 and Nepal's Demographic and Health Surveys 2001, 2006, 2011, and 2016. Second, we constructed pooled multivariable linear regression models and decomposed the contributions of our time-variant determinants on the predicted changes in HAZ and stunting over the past two decades. Our findings indicate substantial improvements in HAZ (38.5%) and reductions in stunting (-42.6%) and severe stunting prevalence (-63.9%) in Nepalese children aged 0-35 months. We also report that the increment in HAZ, across the 1996-2016 period, was significantly associated (confounder-adjusted p < .05) with household asset index, maternal and paternal years of education, maternal body mass index and height, basic child vaccinations, preceding birth interval, childbirth in a medical facility, and prenatal doctor visits. Furthermore, our quantitative decomposition of HAZ identified advances in utilisation of health care and related services (31.7% of predicted change), household wealth accumulation (25%), parental education (21.7%), and maternal nutrition (8.3%) as key drivers of the long-term and sustained progress against child linear growth deficits. Our research reiterates the multifactorial nature of chronic child undernutrition and the need for coherent multisectoral nutrition-sensitive and nutrition-specific strategies at national scale to further improve linear growth in Nepal.

Individual, household and national factors associated with iron, vitamin A and zinc deficiencies among children aged 6-59 months in Nepal

Iron, vitamin A and zinc deficiencies are the top three micronutrients contributing to disability-adjusted life years globally. The study assessed the factors associated with iron, vitamin A, and Zinc deficiencies among Nepalese children (n = 1709) aged 6-59 months using data from the 2016 Nepal National Micronutrient Status Survey. The following cut-off points were applied: iron deficiency [ferritin < 12 μg/L or soluble transferrin receptor (sTfR) > 8.3 mg/L], vitamin A deficiency (retinol-binding protein < 0.69 μmol/L) and zinc deficiency (serum zinc < 65 μg/dl for morning sample and <57 μg/dl for afternoon sample). We used multiple logistic regression adjusted for sampling weights and clustering to examine the predictors of micronutrient deficiencies. The prevalence of iron depletion (ferritin), tissue iron (sTfR), vitamin A and zinc deficiencies were 36.7%, 27.6%, 8.5% and 20.4%, respectively. Children were more likely to be iron deficient (ferritin) if aged 6-23 months, stunted, and in a middle-wealth quintile household. Vitamin A deficiency was associated with development region and was higher among children living in severe food-insecure households and those who did not consume fruits. Zinc deficiency was higher among children in rural areas and the poorest wealth quintile. The Government of Nepal should focus on addressing micronutrient deficiencies in the early years, with emphasis on improving food systems, promote healthy diets, among younger and stunted children and provide social cash transfer targeting high-risk development regions, poorest and food insecure households.

Factors associated with anaemia in a nationally representative sample of nonpregnant women of reproductive age in Nepal

We used cross-sectional data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anaemia among a nationally representative sample of nonpregnant women 15- 49 years (n = 1, 918). Haemoglobin, biomarkers of iron status and other micronutrients, infection, inflammation, and blood disorders were assessed from venous blood. Soil-transmitted helminth and Helicobacter pylori infections were assessed from stool. Sociodemographic, household, and health characteristics and diet were ascertained by interview. We conducted bivariate analyses between candidate predictors and anaemia (haemoglobin <12.0 g/ dL, altitude- and smoking-adjusted). Candidate predictors that were significant in bivariate models (P < 0.05) were included in the multivariable logistic regression model, accounting for complex sampling design. Anaemia prevalence was 20.2% (95% confidence interval [CI] [17.6, 22.8]). Associated with reduced anaemia odds were living in the Mountain and Hill ecological zones relative to the Terai (adjusted odds ratio [AOR] 0.35, 95% CI [0.21, 0.60] and AOR 0.41, 95% CI [0.29, 0.59], respectively), recent cough (AOR 0.56, 95% CI [0.38, 0.82]), hormonal contraceptive use (AOR 0.58; 95% CI [0.38, 0.88]), ln ferritin (micrograms per litre; AOR 0.43, 95% CI [0.35, 0.54]), and ln retinol binding protein (micrograms per litre; AOR 0.20, 95% CI [0.11, 0.37]). Residing in a house with an earth floor (AOR 1.74, 95% CI [1.18, 2.56]), glucose-6- phosphate dehydrogenase deficiency (AOR 2.44, 95% CI [1.66, 3.60]), and haemoglobinopathies (AOR 6.15, 95% CI [3.09, 12.26]) were associated with increased anaemia odds. Interventions that improve micronutrient status, ensure access to hormonal birth control, and replace dirt floors to reduce infection risk might help reduce anaemia in this population.

Acceptance and compliance with micronutrient powder (MNP) among children aged 6-23 months in northern Nigeria

This study sought to understand the utilization patterns and influencing factors of micronutrient powder (MNP) use among children aged 6-23 months in northern Nigeria as part of formative research to inform the design of an infant and young child feeding (IYCF) intervention. It had an iterative, multi-phase design whereby mixed methods data were collected from 144 households participating in an 8-week home-feeding trial. During the first four weeks, 12-hour direct observations were conducted with 24 households using MNP. Over the next four weeks, 18 of the same households were observed. In-depth interviews were also conducted among 27 caregivers to understand factors related to utilization. Unannounced spot checks (n = 86) were also conducted to gauge MNP compliance. Most households (76.7%) (66/86) adhered to instructions for using MNP (Adamawa (34/44 = 77.3%) and Kebbi (32/42 = 76.2%)). Facilitating factors to MNP adherence were identified, most notably the high ease of utilization, with 90.0% of caregivers indicating the MNP was 'easy' or 'very easy' to use. Several barriers to MNP compliance were identified and organized into three domains: product-related (e.g. difficulty opening sachet), child-related (e.g. not finishing fortified staple), and caregiver-related (e.g. difficulty making food daily). In Kebbi and Adamawa, MNP was accepted and utilized according to guidelines among most study participants. Findings may be used for scaling up MNP within a more comprehensive IYCF intervention in northern Nigeria.

Empowering women can improve child dietary diversity in Ethiopia

Women empowerment is an underlying factor of child feeding and nutrition. However, the lack of standardized measurements has made it difficult to design interventions that embed women empowerment and measure their impacts. This study aimed to assess temporal trends in women empowerment in Ethiopia and evaluate their contribution towards improving dietary diversity in infants and young children. We used women and child data from the Ethiopian Demographic and Health Survey 2005, 2011, and 2016, yielding a total sample of 6113 mother-child pairs. The survey-based women's empowerment index (SWPER) developed and validated for use in Africa was used to assess three dimensions of women empowerment: (i) social autonomy, (ii) decision making; and (iii) attitude to violence. We used multiple-linear and multivariable logistic regression to assess the associations between SWPER and the number of food groups consumed/and the minimum dietary diversity (MDD). To determine drivers of changes over time, a regression decomposition analysis was run. Women empowerment indices have improved over the 2005-2016 period, but a significant proportion of women had low standardized SWPER scores for autonomy/social independence (47%) and attitude to violence (49%) domains in 2016. SWPER autonomy and SWPER decision-making scores were strongly associated with the odds of meeting MDD. Changes in women empowerment accounted for 17% of the improvements in MDD between 2005 and 2016. SWPER was a stronger predictor of the change in MDD, than known predictors like wealth, child age, and urban residence. As a critical underlying driver of child nutrition, women empowerment should be boldly addressed and integrated in nutrition interventions.

Subnational mapping for targeting anaemia prevention in women of reproductive age in Ethiopia: A coverage-equity paradox

Anaemia in women of reproductive age (WRA) can be effectively addressed if supported by a better understanding of the spatial variations, magnitude, severity and distribution of anaemia. This study aimed to map the subnational spatial distribution of anaemia (any, moderate and severe forms) among WRA in Ethiopia. We identified and mapped (any, moderate and severe) anaemia hotspots in WRA (n = 14,923) at the subnational level and identified risk factors using multilevel logistic regression. Kulldorff scan statistics were used to identify hotspot regions. Ordinary kringing was used to predict the anaemia prevalence in unmeasured areas. The overall anaemia prevalence increased from 16.6% in 2011 to 23.6% in 2016, a rise that was mostly related to the widening of existing hotspot areas. The primary clusters of (any) anaemia were in Somali and Afar regions. The horn of the Somali region represented a cluster of 330 km where 10% of WRA were severely anaemic. The Oromia-Somali border represented a significant cluster covering 247 km, with 9% severe anaemia. Population-dense areas with low anaemia prevalence had high absolute number of cases. Women education, taking iron-folic-acid tablets during pregnancy and birth-delivery in health facilities reduced the risk of any anaemia (P < 0.05). The local-level mapping of anaemia helped identify clusters that require attention but also highlighted the urgent need to study the aetiology of anaemia to improve the effectiveness and safety of interventions. Both relative and absolute anaemia estimates are critical to determine where additional attention is needed.

Whole egg powder makes nutritious diet more affordable for Ethiopia: A cost of the diet and affordability analysis

Despite sustained nutrition education, consumption of animal source foods (ASFs) has been hindered by their low availability, accessibility and affordability. Drying eggs into powder can reduce transport/storage costs, increase shelf-life and allow easier dosage for use of smaller portions. This study aimed to evaluate the contribution of integrating egg powder to the nutrient adequacy and affordability of diets. Using the 'cost of the diet' analysis, we simulated the incorporation of egg powder into households' and children's diet and evaluated its contribution to the nutrient adequacy and affordability of diets. Analysis of the household consumption and expenditure survey (HCES 2016) revealed that only 0.2% of the total consumption expenditure was allocated for eggs, far below the 2.2% and 4.3% required to allow the consumption of one egg a day by the average and the poorest households, respectively. However, the minimum-cost nutritious diet required only 2.5 g of egg powder/person/day to reduce the cost of the optimized diet by 14% (0-24%), allowing an additional 1.2 million households (~4-6 million individuals) afford the optimized diet. The optimized diet for a child 6-23 months of age could be afforded by all households, except by those in the poorest wealth quintile. But, free distribution of egg powder to households in the poorest wealth quintile, if supplemented by effective nutrition education, can allow them to afford the minimum-cost nutritious diet for their 6- to 23-month child. The simple dehydration of egg into egg powder can have a substantial contribution towards increased egg consumption by increasing the affordability of the minimum-cost nutritious diet.

Nutrition in Nepal: Three decades of commitment to children and women

South Asia has made significant progress in reducing child undernutrition. The prevalence of stunting declined by one third between 2000 and 2019; as a result, in 2019, there were 34 million fewer stunted children than in 2000, indicating that progress for child nutrition is possible and is happening at scale. However, no country in South Asia is on track for all nutrition targets of Sustainable Development Goal 2, and the region has the highest prevalence of stunting (33.2%) and wasting (14.8%) in the world. Nepal, the best performing country in the region, narrowly missed the Millennium Development Goal (MDG) target to half the prevalence of child underweight between 1990 and 2015 and achieved the fastest recorded reduction in stunting prevalence in the world between 2001 and 2011. In 2019, UNICEF Nepal completed a series of papers to examine Nepal's progress on maternal and child nutrition during the MDG era. The series explores the trends, distribution and disparities in stunting, micronutrient deficiencies and feeding practices in children under 5 years and anaemia in adolescents and women. Besides, it reviews national micronutrient programmes (vitamin A supplementation, iron and folic acid supplementation and universal salt iodization) and Nepal's first Multi-Sector Nutrition Plan, to illuminate the success factors and enduring challenges in the policy and programme landscape for nutrition. This overview paper summarizes the evidence from these analyses and examines the implications for the direction of future advocacy, policy and programme actions to improve maternal and child nutrition in Nepal and other similar contexts.

Child growth faltering dynamics in food insecure districts in rural Ethiopia

Child undernutrition disproportionally affects children in low- and middle-income countries. In Ethiopia, both wasting and stunting are serious public health concerns, with high human and economic costs. Understanding the dynamics in ponderal and linear growth faltering is critical to inform the design of innovative interventions that can prevent both wasting and stunting in poor and complex settings. Using two longitudinal studies conducted in 2017 and 2019 in four highland regions of Ethiopia, we evaluated the dynamics and drivers of child growth faltering in children 6-23 months of age (N = 5003). Child wasting prevalence peaked during the first 6 months of life, whereas stunting increased significantly after 6 months of age. Male sex, child illnesses (i.e., diarrhoea or fever) and low consumption of fruits and vegetables were associated with higher odds of acute undernutrition (P < 0.05). The consumption of animal source foods (ASF) was associated with increases (β: 95% CI) in weight-for-length Z-score (WLZ; 0.12: 0.0002; 0.242), whereas fruit or vegetables consumption was associated with increases in midupper arm circumference (MUAC; 0.11 cm: 0.003; 0.209). Only consumption of ASF was the statistically significant predictor of future linear growth (0.14: 0.029; 0.251). Distinct trends in WLZ and MUAC were observed by child sex and age. Improving diet quality through improved nutrition knowledge and increased access and affordability of ASFs, along with effective infection prevention/control measures could prevent both child wasting and stunting concurrently.

Understanding delays in the introduction of complementary foods in rural Ethiopia

Age-appropriate breastfeeding and introduction to complementary foods can shape child feeding practices, ensure adequate energy and nutrient intake and prevent linear growth faltering. This study aimed to assess mothers' and health workers' knowledge of timely introduction to complementary foods and evaluate the relationship between delays in complementary feeding and subsequent linear growth. We conducted two rounds of surveys (March/August 2017) among 249 health workers (n = 249) and caregivers (n = 2635) of children 6-23 months of age. We collected information about socio-demographic characteristics, knowledge and practice related to timely introduction to complementary foods. The study was conducted in households from the Productive Safety Net Programme (PSNP) districts, in four highland regions of Ethiopia. Delays in the introduction to complementary feeding were widespread with 53% of children 6-8 months of age not consuming solid, semisolid or soft foods in the past 24 h. After controlling for child, caregiver and household characteristics, children not introduced to complementary foods by 6-8 months had a 0.48 SD lower length-for-age z-score at 12-15 months. Caregivers' knowledge was strongly and inversely correlated with untimely introduction of complementary foods in logistic regressions (OR = 0.55, p < 0.01). In turn, local health extension worker's knowledge was strongly correlated with caregiver's knowledge. Consequently, frequent and timely visits by health extension workers emphasising not only on what to feed but also when and how to feed a child are needed. Innovative ways of increasing reach, intensity and frequency of nutrition messaging by using the PSNP interactions as an additional point of contact would need to be explored further.

Effects of different drying methods and ascorbic acid pretreatment on carotenoids and polyphenols of papaya fruit in Ethiopia

Frequent consumption of fruits can prevent nutrient deficiencies and promote health. However, the perishability and unaffordability of fruits had led to very low levels of fruit consumption in low- and middle-income countries (LMICs). The objective of this study was to evaluate the retention of nutrients and bioactive compounds of papaya fruit (Carica papaya L) with/without ascorbic acid pretreatment and drying under different techniques, to then estimate the vitamin A intakes for vulnerable population. Yellow pulp ripped papaya fruits (i.e., >75% level of skin color/stage level 4) (n = 14), with and without ascorbic acid pretreatment were dried using (a) solar drying: open-air, tray driers, and glasshouse; (b) refractance window drying; (c) oven drying; and (d) freeze-drying (control). The fresh fruit had high moisture content (87%) and an acidic pH. The dried papaya had a water activity of 0.5-0.6. The highest TPC, TFC, total carotenoids, and ß-carotene were found in freeze-dried papaya samples, followed by refractance window, and solar glass house (p < .05). The highest retention in total carotenoids (81.5%) and ß-carotene (61.9%) relative to freeze-drying was for the refractance-window; 25 g of dried papaya could contribute to 38% of the retinol equivalents' requirement for young children. Ascorbic acid pretreatment increased the retention of total carotenoids, ß-carotene, TPC, and TFC (p < .05) by (6-11)%, (8-34)%, (7-58)%, and (6-30)%, respectively, for all the drying methods. Refractance window and solar glass house drying can improve diets and constitute a promising food systems' intervention that can increase year-round availability, accessibility, and affordability of vitamin A-rich fruits like papaya.

A review of the maternal iron and folic acid supplementation programme in Nepal: Achievements and challenges

In the late 1990s, an estimated 75% of pregnant women in Nepal were anaemic. Although iron and folic acid (IFA) supplements were available free of charge, coverage among pregnant women was very low. In response, the Government of Nepal launched the Iron Intensification Programme (IIP) in 2003 to improve the coverage of IFA supplementation and anthelminthic treatment during pregnancy, as well as promote the utilization of antenatal care. This review examined how the IIP programme contributed to Nepal's success in increasing the consumption of IFA supplements during pregnancy. Nepal's cadre of Female Community Health Volunteers were engaged in the IIP to support the community‐based distribution of IFA supplements to pregnant women and complement IFA distribution through health facilities and outreach services. As a result, the country achieved a fourfold increase in the proportion of women who took IFA supplements during pregnancy between 2001 and 2016 (from 23% to 91%) and a 12‐fold increase in the proportion who took IFA supplements for at least 90 days during pregnancy (from 6% to 71%). The increase in coverage of IFA supplements accompanied an increase in the coverage of antenatal care during the same period. By 2016, the prevalence of anaemia in pregnant women decreased to 46%, highlighting the need to tackle other causes of anaemia and improve haemoglobin concentration before pregnancy, while maintaining the successful efforts to reach pregnant women with IFA supplements at the community level.

Vitamin A supplementation and estimated number of averted child deaths in Ethiopia: 15 years in practice (2005-2019)

Vitamin A supplementation (VAS), started as a short‐term strategy pending dietary improvements, has been implemented in Ethiopia for the last 15 years. We aimed to describe the trends in VAS coverage and estimated the associated reductions in child mortality. VAS coverage data obtained from the District Health Information System and the Demographic and Health Surveys were linked to child mortality data from the United Nations Interagency Group for Child Mortality Estimation (UN IGME). The number of child deaths averted was modelled assuming 12% and 24% reductions in all‐cause mortality. From 2006 to 2011, VAS was delivered through campaigns, and coverage was above 85%. However, from 2011 onwards, VAS delivery was integrated to the routine health system, and the coverage declined to <60% with significant disparities by wealth quintile and rural–urban residence. VAS has saved between 167,563 to 376,030 child lives (2005–2019), but additional lives (>42,000) could have been saved with a universal coverage (95%). Inconsistent supply of vitamin A capsules, but more importantly, low access to health care, and the limited contact opportunities for children after 24 months may have contributed to the declining VAS coverage. Any changes in target or scale‐up should thus consider these spatial and socioeconomic variations. Increasing the coverage of VAS and closing the equity gap in access to nutrition services is critical. However, with alternative programmes like vitamin A fortification being set‐up, the benefits and safety of VAS need to be closely monitored, particularly in areas where there will be overlap.

Wasted Children and Wasted Time: A Challenge to Meeting the Nutrition Sustainable Development Goals with a High Economic Impact to Ethiopia

Despite some progress in the reduction of the prevalence of child wasting in Ethiopia, the pace of progress has been slow. Despite millions of dollars being spent on the treatment of wasting every year, the increased frequency and magnitude of environmental and anthropogenic shocks has halted progress. This study aimed to present the trends of child wasting in Ethiopia and estimate the economic losses related to the slow progress towards meeting the sustainable development goal (SDG) targets. Weather shocks and civil unrest between 2015 and 2018 have halted progress. We used a "consequence model" to apply the coefficient risk-deficit on economic losses established in the global scientific literature to the Ethiopian health, demographic, and economic data to estimate economic losses related to child wasting. The impact of wasting on the national economy of Ethiopia is estimated to be 157.8-230.2 million United States dollars (USD), annually. The greatest contributor to the economic burden (43.5-63.5% of the burden depending on the discount rate) is the cost of supplies and human resources to treat wasting. To reach the 2030 SDGs, Ethiopia should increase its annual average reduction rate (AARR) in the numbers of child (<59 months) wasting from 0.1% to 5.4%. This will avert the wasting in 7.9 million cases and prevent additional economic costs of up to 803.7 million USD over the next decade. Increasing the reach of therapeutic interventions, but also identifying and implementing wasting prevention interventions, will be critical if the SDG targets are to be met and the opportunity of the children to thrive is not to be wasted.

Is the legal framework by itself enough for successful WHO code implementation? A case study from Ethiopia

Since 2016, Ethiopia has passed several proclamations and directives to regulate the promotion of commercial breastmilk substitute (BMS). Ethiopia's market potential will undoubtedly be the gravitating point for international infant formula companies due to growing urbanization, purchasing power, population, and the relatively low use of BMS to-date. The aim of this review is to assess the strengths and weaknesses of the existing laws, standards, and monitoring documents used to regulate the marketing of BMSs in Ethiopia and make future recommendations. The study findings highlighted that the regulation on marketing are comprehensive and strong to limit the promotion of infant formula. On the other hand, the regulation on marketing of follow-up formulas, complementary foods, and growing-up milk by manufacturers and distributors, media houses, and communication and advertisement agencies are underregulated, especially with regards to the international 69.9 regulation. The monitoring and enforcement of the existing marketing regulations remain limited in the absence of a formal coordination mechanism. Several violations of the national BMS regulations were observed. Forty-one percent of mothers reported observing the BMS advertising and logos were detected in 36% of health facilities assessed. In 100% of cases, the infant formula labels contained violations. As the lead national authority mandated to regulate food safety, the Ethiopian Food and Drug Authority needs to update its regulations related to the marketing of BMS to fill the loopholes and revise the national law in line with the international code of marketing of BMSs to protect breastfeeding.

Predictors of micronutrient powder (MNP) knowledge, coverage, and consumption during the scale-up of an integrated infant and young child feeding (IYCF-MNP) programme in Nepal

Large-scale programmes using micronutrient powders (MNPs) may not achieve maximum impact due to limited/inappropriate MNP coverage, consumption, and use. We identify predictors of MNP coverage, maternal knowledge of appropriate use, and child MNP consumption in Nepal. A cross-sectional survey was conducted in 2,578 mother-child pairs representative of children 6-23 months in two districts that were part of the post-pilot, scale-up of an integrated infant and young child feeding-MNP (IYCF-MNP) programme. Children aged 6-23 months were expected to receive 60 MNP sachets every 6 months from a female community health volunteer (FCHV) or health centre. Outcomes of interest were MNP coverage (ever received), maternal knowledge of appropriate use (correct response to seven questions), repeat coverage (receipt ≥ twice; among children 12-23 months who had received MNP at least once, n = 1342), and high intake (child consumed ≥75% of last distribution, excluding those with recent receipt/insufficient time to use 75% at recommended one-sachet-per-day dose, n = 1422). Multivariable log-binomial regression models were used to identify predictors of the four outcomes. Coverage, knowledge of appropriate use, and repeat coverage were 61.3%, 33.5%, and 45.9%, respectively. Among MNP receivers, 97.9% consumed MNP at least once and 38.9% of eligible children consumed ≥75% of last distribution. FCHV IYCF-MNP counselling was positively associated with knowledge, coverage, repeat coverage, and high intake; health worker counselling with knowledge and coverage indicators; and radio messages with coverage indicators only. FCHV counselling had the strongest association with knowledge, coverage, and high intake. Community-based counselling may play a vital role in improving coverage and intake in MNP programmes.

Factors associated with anaemia among adolescent boys and girls 10-19 years old in Nepal

We used data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anaemia (World Health Organization cut-points using altitude- and smoking-adjusted haemoglobin [Hb]) among nationally representative samples of adolescents 10-19 years. Hb, biomarkers of micronutrients, infection and inflammation were assessed from venous blood. Sociodemographic and household characteristics, dietary diversity, pica and recent morbidity were ascertained by interview. We explored bivariate relationships between candidate predictors and anaemia among boys (N = 967) and girls (N = 1,680). Candidate predictors with P < 0.05 in bivariate analyses were included in sex-specific multivariable logistic regression models. Anaemia prevalence was 20.6% (95% confidence interval [CI] [17.1, 24.1]) among girls and 10.9% (95% CI [8.2, 13.6]) among boys. Among girls, living in the Mountain and Hill ecological zones relative to the Terai (adjusted odds ratio [AOR] 0.28, 95% CI [0.15, 0.52] and AOR 0.42, 95% CI [0.25, 0.73], respectively), ln ferritin (μg/L) (AOR 0.53, 95% CI [0.42, 0.68]) and ln retinol binding protein (RBP) (μmol/L) (AOR 0.08, 95% CI [0.04, 0.16]) were associated with reduced anaemia odds. Older age (age in years AOR 1.19, 95% CI [1.12, 1.27]) and Janajati ethnicity relative to the Muslim ethnicity (AOR 3.04, 95% CI [1.10, 8.36]) were associated with higher anaemia odds. Among boys, ln RBP [μmol/L] (AOR 0.25, 95% CI [0.10, 0.65]) and having consumed flesh foods (AOR 0.57, 95% CI [0.33, 0.99]) were associated with lower anaemia odds. Open defecation (AOR 2.36, 95% CI [1.15, 4.84]) and ln transferrin receptor [mg/L] (AOR 3.21, 95% CI [1.25, 8.23]) were associated with increased anaemia odds. Anaemia among adolescents might be addressed through effective public health policy and programs targeting micronutrient status, diet and sanitation.

Age, Ethnicity, Glucose-6-Phosphate Dehydrogenase Deficiency, Micronutrient Powder Intake, and Biomarkers of Micronutrient Status, Infection, and Inflammation Are Associated with Anemia Among Children 6-59 Months in Nepal

BACKGROUND

Anemia is a major concern for children in Nepal; however, little is known about context-specific causes of anemia.

OBJECTIVE

We used cross-sectional data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anemia in a nationally representative, population-based sample of children 6-59 mo (n = 1367).

METHODS

Hemoglobin, biomarkers of iron status and other micronutrients, infection, inflammation, and blood disorders were assessed from venous blood samples. Soil-transmitted helminth (STH) and Helicobacter pylori infections were assessed from stool. Anthropometry was measured with standard procedures. Sociodemographic and household characteristics, diet, micronutrient powder (MNP) intake, pica, and morbidity recall were ascertained by caregiver interview. Multivariable logistic regression that accounted for complex sampling design, determined predictors of anemia (hemoglobin <11.0 g/dL, altitude adjusted); candidate predictors were variables with P < 0.05 in bivariate models.

RESULTS

Anemia prevalence was 18.6% (95% CI: 15.8, 21.4). MNP intake [adjusted OR (AOR): 0.25, 95% CI: 0.07, 0.86], log (ln) ferritin (μg/L) (AOR: 0.49, 95% CI: 0.38, 0.64), and ln RBP (μmol/L) (AOR: 0.42, 95% CI: 0.18, 0.95) were associated with reduced odds of anemia. Younger age (6-23 mo compared with 24-59 mo; AOR: 2.29, 95% CI: 1.52, 3.46), other Terai ethnicities (AOR: 2.59, 95% CI: 1.25, 5.35) and Muslim ethnicities (AOR: 3.15, 95% CI: 1.30, 7.65) relative to Brahmin/Chhetri ethnicities, recent fever (AOR: 1.68, 95% CI: 1.08, 2.59), ln C-reactive protein (mg/L) (AOR: 1.23, 95% CI: 1.03, 1.45), and glucose-6-phosphate dehydrogenase deficiency (AOR: 2.84, 95% CI: 1.88, 4.30) were associated with increased odds of anemia.

CONCLUSION

Both nonmodifiable and potentially modifiable factors were associated with anemia. Thus some but not all anemia might be addressed through effective public health policy, programs, and delivery of nutrition and infection prevention and control.

To see, hear, and live: 25 years of the vitamin A programme in Nepal

Nepal has a rich history of vitamin A research and a national, biannual preschool vitamin A supplementation (VAS) programme that has sustained high coverage for 25 years despite many challenges, including conflict. Key elements of programme success have included (a) evidence of a 26–30% reduction in child mortality from two, in‐country randomized trials; (b) strong political and donor support; (c) positioning local female community health volunteers as key operatives; (d) nationwide community mobilization and demand creation for the programme; and (e) gradual expansion of the programme over a period of several years, conducting and integrating delivery research, and monitoring to allow new approaches to be tested and adapted to available resources. The VAS network has served as a platform for delivering other services, including anthelmintic treatment and screening for acute malnutrition. We estimate that VAS has saved over 45,000 young lives over the past 15 years of attained national coverage. Consumption of vitamin A‐ and carotenoid‐rich foods by children and women nationally remains low, indicating that supplementation is still needed. Current challenges and opportunities to improving vitamin A status include lower VAS coverage among younger children (infants 6–11 months of age), finding ways to increase availability and access to dietary vitamin A sources, and ensuring local programme investments given the recent decentralization of the government.

The evolution, progress, and future direction of Nepal's universal salt iodization program

Nepal is located in what was once known as the Himalayan Goitre Belt and once had one of the highest prevalence's of iodine deficiency disorders in the world. However, through a well‐executed universal salt iodization program implemented over the past 25 years, it has achieved optimal iodine intake for its population, effectively eliminating the adverse consequences of iodine deficiency disorders. A comprehensive review of policy and legislation, surveys, and program reports was undertaken to examine the key elements contributing to the success of this program. The paper reviews the origins and maturation of salt iodization in Nepal, as well as trends in the coverage of iodized salt, the iodine content in salt, and population iodine status over the past two decades. The paper describes critical components of the program including advocacy efforts, trade issues with India, the role of the Salt Trading Corporation, monitoring, and periodic program reviews. The paper discusses the recent findings from the 2016 national micronutrient survey demonstrating the success of the salt iodization program and describes emerging challenges facing the program in the future.

Infant and young child feeding practices and child linear growth in Nepal: Regression-decomposition analysis of national survey data, 1996-2016

Suboptimal infant and young child feeding (IYCF) practices have profound implications on child survival, health, growth, and development. First, our study analysed trends in 18 IYCF indicators and height‐for‐age z‐score (HAZ) and stunting prevalence across Nepal's Family Health Survey 1996 and four rounds of Nepal Demographic and Health Surveys from 2001–2016. Second, we constructed multivariable regression models and decomposed the contribution of optimal IYCF practices on HAZ and stunting prevalence over the 1996–2016 period. Our findings indicate that most age‐appropriate IYCF practices and child linear growth outcomes improved over the past two decades. At present, according to the World Health Organization's tool for national assessment of IYCF practices, duration of breastfeeding is rated very good, early initiation of breastfeeding and exclusive breastfeeding (EBF) are rated good, whereas minimal bottle‐feeding and introduction of solid, semi‐solid or soft foods are rated fair. Our study also reports that a paucity of age‐appropriate IYCF practices—in particular complementary feeding—are significantly associated with increased HAZ and decreased probability of stunting (p < .05). Moreover, age‐appropriate IYCF practices—in isolation—made modest statistical contributions to the rapid and sustained reduction in age‐specific child linear growth faltering from 1996–2016. Nevertheless, our findings indicate that comprehensive multisectoral nutrition strategies—integrating and advocating optimal IYCF—are critical to further accelerate the progress against child linear growth faltering. Furthermore, specific focus is needed to improve IYCF practices that have shown no significant development over the past two decades in Nepal: EBF, minimum acceptable diet, and minimal bottle‐feeding.

Estimating the Double Burden of Malnutrition among 595,975 Children in 65 Low- and Middle-Income Countries: A Meta-Analysis of Demographic and Health Surveys

INTRODUCTION

Given the changing global nutrition landscape, the double burden of malnutrition is a major public health challenge in many developing countries. The main aim of this study is to estimate the double burden of malnutrition among children in low- and middle-income countries (LMICs).

METHODS

This study used cross-sectional data from Demographic and Health Surveys (2001-2016). A meta-analysis was conducted to estimate the prevalence of malnutrition indicators in 595,975 children under five years from 65 LMICs. Significant heterogeneity was detected among the various surveys (I2 >50%), hence a random-effect model was used. Sensitivity analysis was also performed, to examine the effects of outliers.

RESULTS

The pooled estimate for stunting, wasting, underweight, and overweight/obesity was 29.0%, 7.5%, 15.5%, and 5.3% respectively. Countries with the highest coexistence of undernutrition and overweight/obesity were: South Africa (stunting 27.4% (95% CI: 25.1, 29.8); overweight/obesity 13.3% (95% CI: 11.5, 15.2)), Sao Tome and Principe (stunting 29.0% (95% CI: 26.8, 31.4); overweight/obesity 10.5% (95% CI: 9.0, 12.1)), Swaziland (stunting 28.9% (95% CI: 27.3, 30.6); overweight/obesity 10.8% (95% CI: 9.7, 12.0)), Comoros (stunting 30.0% (95% CI: 28.3, 31.8); overweight/obesity 9.3% (95% CI: 8.3, 10.5)), and Equatorial Guinea (stunting 25.9% (95% CI: 23.4, 28.7); overweight/obesity 9.7% (95% CI: 8.0, 11.6)).

CONCLUSIONS

There is an urgent need to strengthen existing policies on child malnutrition to integrate and scale up opportunities for innovative approaches which address the double burden of malnutrition in children under five years in LMICs.

The impact of unconditional child cash grant on child malnutrition and its immediate and underlying causes in five districts of the Karnali Zone, Nepal - A trend analysis

BACKGROUND

The impact of unconditional cash transfers on child malnutrition and its determinants remains poorly understood. The aim of this study was evaluate the impact of an unconditional child cash grant on children's nutritional status and its immediate (infant and young child feeding, dietary diversity, food consumption, and child infection and care) and underlying (household food security; Water, Hygiene and Sanitation (WASH) determinants among children younger than five years in the Karnali Zone, Nepal.

METHODS

The five districts of the Karnali Zone received standard social welfare services in the form of targeted resource transfers for eligible families, plus an unconditional child cash payment, augmented by a capacity building and behavioural change education. Repeated cross-sectional surveys, with measures taken at baseline (2009, N=3750), midline (2013, N=3750) and endline (2015, N=3647), were carried out using a two-stage cluster sampling method. Multi-level Generalized Linear Mixed Models (GLMMs) with normal, binomial, Poisson, or multinomial link were performed to detect the unadjusted and adjusted trends.

RESULTS

There was a linear growth among children, with a corresponding increase of 0.41 height-for-age Z-scores (p < 0.001), 0.50 weight-for-age Z-scores (p<0.001), and 0.34 weight-for-height Z-scores (p<0.001) between the study period, equating to a decline in child undernutrition of 9.4, 16.5, and 5.1 percentage points (p<0.001) for stunting, underweight, and wasting respectively. Improvements were also observed in WASH outcomes, care and health seeking behaviours, and food availability.

CONCLUSION

Unconditional child cash grant embedded within a government sponsored cash transfer program for families and complemented by capacity building and behavioural change strategies improves child nutritional status and its determinants.

Changes in growth, anaemia, and iron deficiency among children aged 6-23 months in two districts in Nepal that were part of the post-pilot scale-up of an integrated infant and young child feeding and micronutrient powder intervention

There is limited research on integrated infant and young child feeding (IYCF) and micronutrient powders (MNPs) programmes operating at scale, despite widespread implementation. This study uses cross-sectional baseline (n = 2,542) and endline (n = 2,578) surveys representative of children 6-23 months in two districts in Nepal that were part of a post-pilot scale-up of a IYCF-MNP programme. Multivariable log-binomial regression models were used to estimate prevalence ratios (PRs) for stunting (length-for-age z-score <-2), wasting (weight-for-length z-score <-2), underweight (weight-for-age z-score <-2), anaemia (altitude-adjusted haemoglobin <110 μg/L), moderate or severe anaemia (altitude-adjusted haemoglobin <100 g/L), iron deficiency (inflammation-adjusted ferritin <12 μg/L), and iron deficiency anaemia (iron deficiency + anaemia [IDA]) at endline versus baseline and also to compare children in the endline survey based on frequency of mothers' interactions with female community health volunteers (FCHVs; >1× per month or monthly vs. <1× per month) and MNP coverage (1 or ≥2 distributions vs. none among children 12-23 months). Endline children were significantly less likely to be stunted than baseline children in both districts (multivariable-adjusted PR [95% CI]: 0.77 [0.69, 0.85], P < 0.001 and 0.82 [0.75, 0.91], P < 0.001 in Kapilvastu and Achham, respectively); however, only Achham had significantly lower prevalences of underweight, moderate/severe anaemia, iron deficiency, and IDA at endline. At endline, 53.5% and 71.4% of children had tried MNP in Kapilvastu and Achham districts, respectively, consuming an average of 24 sachets from the last distribution. Frequent maternal-FCHV interactions were associated with a reduced risk of stunting and underweight at endline, whereas repeat MNP coverage was associated with reduced risk of anaemia and IDA. Future research using experimental designs should verify the potential of integrated IYCF-MNP programmes to improve children's nutritional status.

Sociodemographic factors associated with inadequate food group consumption and dietary diversity among infants and young children in Nepal

Infants and young children need diversified diets to grow healthy. However, there is limited evidence on factors associated with consumption of various food groups. This study aimed to identify the sociodemographic factors associated with inadequate food group consumption and not meeting the minimum dietary diversity (MDD) among infants and young children aged 6-23 months in Nepal. Using cross-sectional data from the 2016 Nepal Demographic and Health Survey, the factors at the individual-, household-, and community-levels associated with not consuming foods from the seven food groups, which are grains, roots and tubers, legumes and nuts, dairy products, flesh foods, eggs, vitamin-A rich fruits and vegetables, and other fruits and vegetables, and not meeting the MDD were examined. The least consumed food group was eggs, followed by flesh foods and 46.5% of children received the MDD. Children aged 6-11 months had higher odds of not consuming foods from the seven food groups and not meeting the MDD than older children. Children from the poorest quintile had higher odds of not consuming legumes and nuts, dairy products, flesh foods, and other fruits and vegetables, and not meeting the MDD. Children from Terai/Madhesi Other had higher odds of not consuming foods from the seven food groups compared to those from the other groups. Children from Province 2 had higher odds of not consuming eggs, vitamin-A rich fruits and vegetables, and other fruits and vegetables, and not meeting the MDD. Dietary diversity among children in Nepal needs improvement. National policies and programs need to promote the consumption of diverse food groups by considering different sociodemographic characteristics.

Good governance, public health expenditures, urbanization and child undernutrition Nexus in Ethiopia: an ecological analysis

Background

Child undernutrition remains the major public health problem in low and middle-income countries including Ethiopia. The effects of good governance, urbanization and public health expenditure on childhood undernutrition are not well studied in developing countries. The objective of the study is to examine the relationship between quality of governance, public health expenditures, urbanization and child undernutrition in Ethiopia.

Methods

This is pooled data analysis with ecological design. We obtained data on childhood undernutrition from the Ethiopian Demographic and Health Surveys (EDHS) that were conducted in 2000, 2005, 2011 and 2016. Additionally, data on quality of governance for Ethiopia were extracted from the World Governance Indicators (WGI) and public health spending and urbanization were obtained from the World Development Indicators and United Nations’ World Population Prospects (WPP) respectively. Univariate and multivariate analysis were done to assess the relationship between governance, public health expenditure and urbanization with childhood undernutrition.

Result

Government effectiveness (adjusted odd ratio (AOR) = 20.7; p = 0.046), regulatory quality (AOR = 0.0077; p = 0.026) and control of corruption (AOR = 0.0019; p = 0.000) were associated with stunting. Similarly, government effectiveness (AOR = 72.2; p = 0.007), regulatory quality (AOR = 0.0015; p = 0.004) and control of corruption (AOR = 0.0005; p = 0.000) were associated with underweight. None of the governance indicators were associated with wasting. On the other hand, there is no statistically significant association observed between public health spending and urbanization with childhood undernutrition. However, other socio-demographic variables play a significant effect on reducing of child undernutrition.

Conclusion

This study indicates that good governance in the country plays a significant role for reducing childhood undernutrition along with other socio-demographic factors. Concerned bodies should focus on improving governance and producing a quality policy and at the same time monitor its implementation and adherence.

Gender differences in factors associated with prehypertension and hypertension in Nepal: A nationwide survey

BACKGROUND

Nepal has one of the highest prevalence of hypertension in South Asia. However, no national studies have examined the gender differences in the determinants of prehypertension and hypertension in the country to inform targeted interventions. This study aimed to investigate gender differences in factors associated with prehypertension and hypertension in Nepal using the 2016 Nepal Demographic and Health Survey (NDHS).

METHODS

Sociodemographic, behavioural, anthropometric and health status data and information on hypertension were obtained from 14,857 (males: 6,245 and females: 8,612) individuals aged 15 years or above from the biomarker sample of the 2016 NDHS. Factors associated with prehypertension and hypertension by gender were investigated using generalized linear latent and mixed models (GLLAM) with the mlogit link and binomial family that adjusted for clustering and sampling weights.

RESULTS

The overall prevalence of prehypertension and hypertension was 26.9% [95% confidence interval (CI): 25.7, 28.1] and 17.2% (95% CI 16.1, 18.3), respectively. Prehypertension was present in 30.4% (95%CI: 28.7, 32.2) of males and 24.3% (95% CI: 23.1, 25.6) of females, while hypertension was present in 20.4%, (95% CI 18.9, 22.0) of males and 14.8% (95% CI: 13.7, 16.0) of females. Key modifiable factors that were strongly associated with prehypertension and hypertension in both genders included overweight and obesity, caffeine intake, tobacco use, no schooling, previously informed of hypertension in a health facility, and alcohol consumption (for males). Other significant factors associated with prehypertension and hypertension included increasing age (> 30 years), ecological zone (Hill), Developmental zone (Western) and being married.

CONCLUSION

Our results suggest that prehypertension and hypertension were higher in males compared to females. Interventions to improve awareness, screening, treatment and control of prehypertension and hypertension in Nepal are warranted and should target key modifiable factors, as well as people aged 30 years and above.

Infant and Young Child Feeding (IYCF) Practices Improved in 2 Districts in Nepal during the Scale-Up of an Integrated IYCF and Micronutrient Powder Program

BACKGROUND

Three-quarters of the ≥50 programs that use micronutrient powders (MNPs) integrate MNPs into infant and young child feeding (IYCF) programs, with limited research on impacts on IYCF practices.

OBJECTIVE

This study assessed changes in IYCF practices in 2 districts in Nepal that were part of a post-pilot scale-up of an integrated IYCF-MNP program.

METHODS

This analysis used cross-sectional surveys (n = 2543 and 2578 for baseline and endline) representative of children aged 6-23 mo and their mothers in 2 districts where an IYCF program added MNP distributions through female community health volunteers (FCHVs) and health workers (HWs). Multivariable log-binomial models estimated prevalence ratios comparing reported IYCF at endline with baseline and at endline on the basis of exposure to different sources of IYCF information. Mothers who received FCHV-IYCF counseling with infrequent (≤1 time/mo) and frequent (>1 time/mo) interactions were compared with mothers who never received FCHV-IYCF counseling. The receipt of HW-IYCF counseling and receipt of MNPs from an FCHV (both yes or no) were also compared.

RESULTS

The prevalence of minimum dietary diversity (MDD) and minimum acceptable diet (MAD) was significantly higher at endline than at baseline. In analyses from endline, compared with mothers who never received FCHV counseling, only mothers in the frequent FCHV-IYCF counseling group were more likely to report feeding the minimum meal frequency (MMF) and MAD, with no difference for the infrequent FCHV-IYCF counseling group in these indicators. HW-IYCF counseling was not associated with these indicators. Mothers who received MNPs from their FCHV were more likely to report initiating solid foods at 6 mo and feeding the child the MDD, MMF, and MAD compared with mothers who did not, adjusting for HW- and FCHV-IYCF counseling and demographic covariates.

CONCLUSIONS

Incorporating MNPs into the Nepal IYCF program did not harm IYCF and may have contributed to improvements in select practices. Research that uses experimental designs should verify whether integrated IYCF-MNP programs can improve IYCF practices.

Mid-upper-arm circumference based case-detection, admission, and discharging of under five children in a large-scale community-based management of acute malnutrition program in Nigeria

Background

Severe acute malnutrition (SAM) threatens the lives of millions of children worldwide particularly in low and middle-income countries (LMICs). Community-based management of acute malnutrition (CMAM) is an approach to treating large numbers of cases of severe acute malnutrition (SAM) in a community setting. There is a debate about the use of mid-upper arm circumference (MUAC) for admitting and discharging SAM children. This article describes the experience of using MUAC for screening, case-finding, referral, admission, and discharge in a large-scale CMAM program delivered through existing primary health care facilities in Nigeria.

Methods

Over one hundred thousand (n = 102,245) individual CMAM beneficiary records were collected from two of the eleven states (i.e. Katsina and Jigawa) that provide CMAM programming in Nigeria. The data were double entered and checked using EpiData version 3.2 and analyzed using the R language for data-analysis graphics.

Results

The median MUAC at admission was 109 mm. Among admissions, 37.4% (38,275) had a comorbidity recorded at admission and 7.4% (7537) were recorded as having developed comorbidity during the treatment. Analysis in the better performing state program in the most recent year for which data were available found that 87.1% (n = 13,273) of admitted cases recovered and were discharged as cured, 9.2% (n = 1396) defaulted and were lost to follow-up, 2.9% (n = 443) were discharged as non-recovered, 0.7% (n = 104) were transferred to inpatient services, and 0.2% (n = 27) were known (died, to be dead or to have passed) during the treatment episode. The program met SPHERE minimum standards for treatment outcomes for therapeutic feeding programs. Factors associated with negative outcomes (default, non-recovery, transfer, and death) were distance between home and the treatment center; lower MUAC, diarrhea and cough at admission; or developing diarrhea, vomiting, fever, or cough during the treatment episode.

Conclusions

This study confirms that MUAC can be used for both admitting and discharging criteria in CMAM programs with MUAC < 115 mm for admission and MUAC > = 115 mm or at discharge (a higher discharge threshold could be used). Long distances between home and treatment centers, lower MUAC at admission, or having diarrhea, vomiting, fever, or cough during the treatment episode were factors associated with negative outcome. Providing CMAM services closer to the community, using mobile and / or satellite clinics, counseling of mothers by health workers to encourage early treatment seeking behavior, and screening of patients at each patient visit for early detection and treatment of comorbidities are recommended.

The Synergetic Effect of Cash Transfers for Families, Child Sensitive Social Protection Programs, and Capacity Building for Effective Social Protection on Children's Nutritional Status in Nepal

OBJECTIVE

The aim of this study was to evaluate the effectiveness of the synergetic effect of child sensitive social protection programs, augmented by a capacity building for social protection and embedded within existing government's targeted resource transfers for families on child nutritional status.

DESIGN

A repeat cross-sectional quasi-experimental design with measures taken pre- (October-December 2009) and post- (December 2014-February 2015) intervention in the intervention and comparison district. The comparison district received standard social welfare services in the form of targeted resource transfers (TRTs) for eligible families. The intervention district received the TRTs plus a child cash payment, augmented by a capacity building for effective social protection outcomes. Propensity scores were used in difference-in-differences models to compare the changes over time between the intervention and control groups.

RESULTS

Propensity score matched/weighted models produced better results than the unmatched analyses, and hence we report findings from the radius matching. The intervention resulted in a 5.16 (95% CI: 9.55, 0.77), 7.35 (95% CI: 11.62, 3.08) and 2.84 (95% CI: 5.58, 0.10) percentage point reduction in the prevalence of stunting, underweight, and wasting among children under the age, respectively. The intervention impact was greater in boys than girls for stunting and wasting; and greater in girls than boys for underweight. The intervention also resulted in a 6.66 (95% CI: 2.13, 3.18), 11.40 (95% CI: 16.66, 6.13), and 4.0 (95% CI: 6.43, 1.78) percentage point reduction in the prevalence of stunting, underweight, and wasting among older children (≥24 months). No impact was observed among younger children (<24 months).

CONCLUSIONS

Targeted resource transfers for families, augmented with a child sensitive social protection program and capacity building for social protection can address effectively child malnutrition. To increase the intervention effectiveness on younger children, the child cash payment amount needs to be revisited and closely embedded into infant and young child feeding initiatives, but also adjusted to equate to 20% of household expenditure or more to maximize the diversity of food available to young children.

Trends and predictors of appropriate complementary feeding practices in Nepal: An analysis of national household survey data collected between 2001 and 2014

There is evidence that suboptimal complementary feeding contributes to poor child growth. However, little is known about time trends and determinants of complementary feeding in Nepal, where the prevalence of child undernutrition remains unacceptably high. The objective of the study was to examine the trends and predictors of suboptimal complementary feeding in Nepali children aged 6–23 months using nationally representative data collected from 2001 to 2014. Data from the 2001, 2006, and 2011 Nepal Demographic and Health Surveys and the 2014 Multiple Indicator Cluster Survey were used to estimate the prevalence, trends and predictors of four WHO‐UNICEF complementary feeding indicators: timely introduction of complementary foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD). We used multilevel logistic regression models to identify independent factors associated with these indicators at the individual, household and community levels. In 2014, the weighted proportion of children meeting INTRO, MMF, MDD, and MAD criteria were 72%, 82%, 36% and 35%, respectively, with modest average annual rate of increase ranging from 1% to 2%. Increasing child age, maternal education, antenatal visits, and community‐level access to health care services independently predicted increasing odds of achieving MMF, MDD, and MAD. Practices also varied by ecological zone and sociocultural group. Complementary feeding practices in Nepal have improved slowly in the past 15 years. Inequities in the risk of inappropriate complementary feeding are evident, calling for programme design and implementation to address poor feeding and malnutrition among the most vulnerable Nepali children.

Improving estimates of the burden of severe acute malnutrition and predictions of caseload for programs treating severe acute malnutrition: experiences from Nigeria

Background

The burden of severe acute malnutrition (SAM) is estimated using unadjusted prevalence estimates. SAM is an acute condition and many children with SAM will either recover or die within a few weeks. Estimating SAM burden using unadjusted prevalence estimates results in significant underestimation. This has a negative impact on allocation of resources for the prevention and treatment of SAM. A simple method for adjusting prevalence estimates intended to improve the accuracy of burden estimates and caseload predictions has been proposed. This method employs an incidence correction factor. Application of this method using the globally recommended incidence correction factor has led to programs underestimating burden and caseload in some settings.

Methods

A method for estimating a locally appropriate incidence correction factor from prevalence, population size, program caseload, and program coverage was developed and tested using data from the Nigerian national SAM treatment program.

Results

Applying the developed method resulted in errors in caseload prediction of about 10%. This is a considerable improvement upon the current method, which resulted in a 79.5% underestimate. Methods for improving the precision of estimates are proposed.

Conclusions

It is possible to considerably improve predictions of caseload by applying a simple model to data that are readily available to program managers. This implies that more accurate estimates of burden may also be made using the same methods and data.

Exclusive breastfeeding practice in Nigeria: a bayesian stepwise regression analysis

Despite the importance of breast milk, the prevalence of exclusive breastfeeding (EBF) in Nigeria is far lower than what has been recommended for developing countries. Worse still, the practise has been on downward trend in the country recently. This study was aimed at investigating the determinants and geographical variations of EBF in Nigeria. Any intervention programme would require a good knowledge of factors that enhance the practise. A pooled data set from Nigeria Demographic and Health Survey conducted in 1999, 2003, and 2008 were analyzed using a Bayesian stepwise approach that involves simultaneous selection of variables and smoothing parameters. Further, the approach allows for geographical variations at a highly disaggregated level of states to be investigated. Within a Bayesian context, appropriate priors are assigned on all the parameters and functions. Findings reveal that education of women and their partners, place of delivery, mother's age at birth, and current age of child are associated with increasing prevalence of EBF. However, visits for antenatal care during pregnancy are not associated with EBF in Nigeria. Further, results reveal considerable geographical variations in the practise of EBF. The likelihood of exclusively breastfeeding children are significantly higher in Kwara, Kogi, Osun, and Oyo states but lower in Jigawa, Katsina, and Yobe. Intensive interventions that can lead to improved practise are required in all states in Nigeria. The importance of breastfeeding needs to be emphasized to women during antenatal visits as this can encourage and enhance the practise after delivery.
