Policies to reduce undernutrition include child development

Nearly half of HIV-positive children attending public health facilities are suffering from chronic under-nutrition in conflict-affected zones of Southern Ethiopia

Background

In combination with HIV infection, malnutrition is a complicated medical condition with high morbidity and mortality rates in affected children due to a variety of socioeconomic and medical etiological variables. To combat this, information from a range of contexts is required, but there is little evidence, particularly about the nutritional status of under 15 living with HIV in impoverished communities such as conflict affected areas. Therefore, in this study the magnitude and related factors of stunting among under 15 children antiretroviral therapy at public health facilities was assessed.

Methods

An institution-based cross-sectional study was conducted among under 15 children living with HIV in conflict-affected zones of Southern Ethiopia. After providing written informed consent to study participants, data were collected using an interviewer-administered questionnaire and anthropometric measurements. Bivariable and multivariable logistic regression models were used to identify factors associated with nutritional status, using SPSS Version 25.

Results

Of the 401 participants, 197 (49.1%, 95% CI: 0.44, 0.54) had height-for-age z-score ≤ -2. In the multivariable analysis, larger household size (AOR = 1.58, 95% CI: 1.04-2.40), dietary diversity (AOR = 1.78; 95% CI: 1.07-2.96) and having a history of recurrent diarrhea (AOR = 1.96; 95% CI: 1.07-3.59) were significantly associated with chronic under nutrition.

Conclusions

The prevalence found in this study was high when compared with the stunting target set in SDG, which states to end all forms of malnutrition In order to mitigate the negative health effects of diarrhea during HIV therapy, extra attention needs to be paid to facilitate timely detection and on-going monitoring. Nutrition programs in conflict-affected areas need to consider households with larger family sizes and/or routinely having fewer food groups.

Attention Test Assessment from a Cluster Randomized Controlled Trial of Caregiver Training for Ugandan Preschool Children Living with Perinatal HIV

Fifty-six Ugandan mothers/caregivers received Mediational Intervention for Sensitizing Caregivers (MISC) biweekly for one year; 46 mothers received treatment-as-usual. Preschool PHIV child attention was measured by proportion of time viewing a 7-min animation (early childhood vigilance test or ECVT) at enrollment, 6 and 12 months. Analysis of covariance compared ECVT outcomes for the two intervention groups, controlling for baseline ECVT performance, age and weight-for-age z scores. Differences by trial arm were not significant at any of the three time points. MISC trial-arm children on combination ART during the study period displayed more stable ECVT scores across time points compared to controls.

Effect of short-term educational intervention on complementary feeding index among infants in rural Bangladesh: a randomized control trial

BACKGROUND

Timely, adequate and appropriate Complementary Feeding (CF) is essential for the growth and cognitive development of infants, but until today, evidence-based information is scarce in terms of impact evaluation of CF index (CFI). The study aimed to examine the effect of the short-term intervention of promoting CF practices on the nutritional status of infants in rural Bangladesh.

METHODS

An educational-intervention study followed a randomized controlled trial (RCT) design (NCT03024710). Mothers and family members in the intervention arm received intensive counselling on CF through community health workers (CHWs), whereas existing healthcare services were received in the comparison arm. The study was carried out in the rural Matlab sub-district of Bangladesh between April 2011 and March 2013. In the specified study areas among 360 mother-infant pairs systematically assigned into intervention group and comparison group. Short-term educational intervention on CF was provided for the intervention group and existing services were un-intervened for the comparison group. The outcome of interventions was evaluated after the implementation period using Generalized equation estimation model.

RESULTS

At baseline, the study participants were not different except mean height (p = 0.04), weight-for-age Z score (WAZ) (p = 0.03) and religion (p = 0.04) in between two groups. The mean CFI was significantly higher at intervention area than the comparison and higher category of CFI (score 10 or more) was significantly higher at intervention area than comparison. After adjustment, one-unit CFI increased height-for-age z score by 0.07 units and decreased WAZ by 0.13 units in the intervention group but not significantly changed observed at comparison group.

CONCLUSION

Guided short-term nutritional intervention and developed CFI indicated a significantly better score in intervention area than comparison groups and would be a well adaptable tool for future studies.

TRIAL REGISTRATION

The trial was registered ( NCT03024710 ) at clinical trial registration website. Date of registration: 1/19/2017. Name of the registry: Clinical Trial.gov. Date of registration: 19/1/2017 (retrospective registered). URL of trial: https://clinicaltrials.gov/ct2/show/NCT03024710.

Under-nutrition and associated factors among children infected with human immunodeficiency virus in sub-Saharan Africa: a systematic review and meta-analysis

Background

In the developing world, such as the sub-Saharan African region, HIV/AIDS has worsened the impact of under-nutrition in children. HIV infected children are highly vulnerable to under-nutrition. Therefore, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of under-nutrition, and the pooled effect sizes of associated factors among HIV-infected children in sub-Saharan Africa.

Methods

The primary studies for this review were retrieved from PubMed/ MEDLINE online, Science Direct, Hinari, web of science, CINHAL, EMBASE, WHO databases, Google, and Google Scholar databases. The articles selected for this meta-analysis were published between 2010 and 2020. The last search date was 18 October 2021. The data was extracted in Microsoft Excel format and exported to STATA Version 14.0. A random effect meta-analysis model was used. Heterogeneity was evaluated by the I² test. The Egger weighted regression test was used to assess publication bias.

Results

We retrieved 847 records from these databases. Of which records, 813 were excluded due to different reasons and 34 studies were included in the final analysis. The pooled prevalence of stunting, underweight and wasting in HIV infected children was 46.7% (95% CI; 40.36–53.07, I² = 98.7%, p < 0.01), 35.9% (95% CI; 30.79–41.02, I² = 97.4% p < 0.01), and 23.0% (95% CI; 18.67–27.42, I² = 96.9%, p < 0.01) respectively. The advanced WHO HIV/AIDS clinical staging (III&IV) [OR = 6.74 (95%: 1.747, 26.021), I² = 94.7%] and household food insecurity were associated with stunting [OR = 5.92 (95% CI 3.9, 8.87), I² = 55.7%]. Low family economic status [OR = 4.737 (95% CI: 2.605, 8.614), I² = 31.2%] and increased feeding frequency [OR = 0.323 (95% CI: 0.172, 0.605), I² = 69.8%] were significantly associated with under-weight. Anemia [OR = 2.860 (95% CI: 1.636, 5.000), I² = 74.8%] and diarrhea in the previous month [OR = 4.117 (95% CI: 2.876, 5.894), I² = 0.0%] were also associated with wasting among HIV infected children in sub-Saharan Africa.

Conclusions

The pooled prevalence of under-nutrition among HIV infected children was high. Nutritional assessment and interventions need great attention as a part of HIV care for HIV positive children. The implementation of policies and strategies established by national and international stakeholders in ART care centres should take a maximum emphasis on reducing under-nutrition among HIV infected children.

Determinants of motor, language, cognitive, and global developmental delay in children with complicated severe acute malnutrition at the time of discharge: An observational study from Central India

Background

Undernutrition leads to impaired psychosocial and cognitive development. This study explored the developmental status of children with complicated severe acute malnutrition (SAM) and correlated it with various risk factors for SAM.

Methods and findings

We recruited 100 children with SAM and no other associated significant health issues during the recovery phase of treatment using the Bayley Scales of Infant and Toddler Development III prior to discharge from the nutritional rehabilitation unit in R D Gardi Medical College, Ujjain, Central India. We also assessed composite developmental scores, developmental age equivalents, and average differences in developmental age. Risk factors for developmental delay were identified in children with complicated SAM. The results revealed that 75%, 75%, and 63% of children with SAM exhibited delay in motor (mean score: 78.22), language (mean score: 83.97), and cognitive (mean score: 78.06) domains, respectively. A total of 63% children exhibited delay by an average of 4–7 months in the total developmental age. The proportion of children with delay in motor, language, and cognitive domains was determined. An increased risk of global developmental delay was observedin children with a low birth weight (adjusted odds ratio [aOR]: 18.06, 95%CI: 2.08–156.56; P = 0.009), having working mothers (aOR: 17.54, 95%CI: 3.02–102.59; P = 0.001), weight-for-age less than three standard deviations (aOR: 6.09, 95%CI: 1.08–34.10; P = 0.04), and presence of severe anemia (aOR: 16.34, 95%CI: 2.94–90.73; P = 0.001).

Conclusions

The results indicated that children with SAM exhibit developmental delay across all domains. Identifying multiple modifiable risk factors for developmental delay in children with SAM will be helpful in devising early interventional strategies in low-middle income countries; however, the exact timing of such interventions should be investigated.

Developmental and behavioural problems in children with severe acute malnutrition in Malawi: A cross-sectional study

Background

Early childhood development provides an important foundation for the development of human capital. Although there is a clear relation between stunting and child development outcomes, less information is available about the developmental and behavioural outcomes of children with severe acute malnutrition (SAM). Particularly an important research gap exists in Sub–Saharan Africa where there is a high prevalence of SAM and a high rate of co–occurring HIV (human immune deficiency virus) infection. Our first objective was to assess the prevalence and severity of developmental and behavioural disorders on a cohort of children admitted to an inpatient nutritional rehabilitation centre in Malawi. Our second objective was to compare the developmental and behavioural profiles of children with the two main phenotypes of SAM: kwashiorkor and marasmus.

Methods

This was a cross–sectional observational study including all children hospitalized with complicated SAM in Blantyre, Malawi over an 8–month period from February to October 2015. At discharge, children were assessed with the well-validated Malawi Developmental Assessment Tool (MDAT) for gross motor, fine motor, language and social development. In children ≥24 months, emotional and behavioural problems were measured using the Strengths and Difficulties Questionnaire (SDQ).

Results

150 children (55% boys) with SAM were recruited; mean age of 27.2 months (standard deviation 17.9), 27 children (18%) had pre–existing neurodisabilities (ND) and 34 (23%) had a co–occurring human immune deficiency virus (HIV) infection. All children with SAM experienced profound delays in the gross and fine motor, language and social domains. Linear regression analysis demonstrated that children with kwashiorkor scored 0.75 standard deviations lower (95% confidence interval –1.43 to –0.07) on language MDAT domain than children with marasmus when adjusted for covariates. The prosocial behaviour score of the SDQ was low in children with SAM, indicating a lack of sensitive behaviour in social interactions.

Conclusions

Children with SAM have severe developmental delays after a hospital admission. Our results indicate that there might be a significant difference in developmental attainment between children with kwashiorkor and with marasmus. Future studies exploring longer–term outcomes and testing possible intervention strategies are urgently needed.

Process evaluation of integrated early child development care at private clinics in poor urban Pakistan: a mixed methods study

Background

In poor urban Pakistan, private GP clinics lack adequate services to promote early child development (ECD) care. A clinic-based contextualised ECD intervention was developed for quarterly tool-assisted counselling of mothers.

Aim

To explore the experience and implementation of ECD intervention by the private care providers and clients, for further adaptation for scaling of quality ECD care, at primary level private healthcare facilities in Pakistan.

Design & setting

A mixed methods approach using quantitative records review and qualitative interviews at poor urban clinics in Rawalpindi and Lahore, Pakistan.

Method

Quantitative data from study-specific records were reviewed for 1242 mother-child pairs registered in the intervention. A total of 18 semi-structured interviews with clinic staff, mothers, and research staff were conducted at four clinics. The interviews were audiorecorded and transcribed verbatim.

Results

District Health Office (DHO) support allowed transparent and effective selection and training of clinic providers. Public endorsement of ECD care at private clinics and the addition of community advocates promoted ECD care uptake. Clinic settings were found feasible for clinic assistants, and acceptable to mothers, for counselling sessions. Mothers found ECD counselling methods more engaging compared to the usual care provided.

Conclusion

In poor urban settings where public health care is scarce, minimal programme investment on staff training and provision of minor equipment can engage private clinics effectively in delivering ECD care.

Identifying interventions to help rural Kenyan mothers cope with food insecurity: results of a focused ethnographic study

Abstract

An ethnographic study was conducted in two areas in southern and western Kenya to identify potential interventions to improve the quality, availability and affordability of foods consumed by infants and young children. A cultural–ecological model of determinants of nutrition identified the sectors of information for data collection related to infant and young child (IYC) diet and feeding‐related behaviours, and the focused ethnographic study manual was used to guide the research. The results provide qualitative evidence about facilitators and constraints to IYC nutrition in the two geographical areas and document their inter‐connections. We conclude with suggestions to consider 13 potential nutrition‐sensitive interventions. The studies provide empirical ethnographic support for arguments concerning the importance of combining nutrition‐specific and nutrition‐sensitive interventions through a multi‐sectoral, integrated approach to improve the nutrition of infants and young children in low‐income, resource‐constrained populations. They also document the value of ethnography as a component of landscape analysis in nutrition programme and policy planning.

Key messages

In addition to constraints on infant and young child diet that originate in environmental and technological conditions in both agro‐ecological zones, other factors that affect feeding practices include features of social organisation, household access to social support, caregivers income‐earning activities and their own health.

The results of the ethnographies, which highlight the importance of obtaining the knowledge and perspectives of caregivers of infants and young children, reveal the interactions of the multiple factors that affect child nutrition and the need for simultaneous nutrition‐sensitive interventions to complement nutrition‐specific intervention actions.

Most caregivers in both areas not only understood the importance of diet and food quality for child survival, they also regarded it as essential for child growth and development. This indicates that caregivers in these rural Kenyan communities have adopted the basic biomedical interpretation of the importance of child nutrition as an integral part of their ‘knowledge frameworks’.

Fathers' Perception, Practice, and Challenges in Young Child Care and Feeding in Ethiopia

BACKGROUND

The role of fathers in proper nutrition of young children has not been a frequent topic of studies. Mothers are usually the primary caregivers for young children. However, the father is often responsible for the financial choices of the household, especially in developing countries; we wondered to what extent fathers were involved in child feeding.

OBJECTIVE

This study aimed to investigate the extent of perceptions, practices, and challenges of fathers from low-income settings in routine child care, particularly in relation to child-feeding practices.

METHODS

A qualitative study was conducted in northern Ethiopia. Ten fathers, who had children between 6 and 23 months, were participated in the study. To validate fathers' comments, 10 mothers (from different households) also participated. In-depth interviews and focus group discussions were carried out. A thematic analysis was completed to identify emergent themes within the data.

RESULTS

In general, traditional fathers, fathers in transition, and modern fathers are the 3 types of fathers identified based on their perception, practice, and challenges of routine child care and feeding.

CONCLUSION

Our findings provide new insight to the literature in describing fathers' roles and challenges in routine child-care and feeding practices. We have developed a model that could help researchers, programmers, policy makers, and health workers to approach fathers in different child intervention research and plans. Our findings suggest that targeting fathers may be a worthwhile approach and that it seems justifiable to plan interventions involving fathers.

Mineral- and vitamin-enhanced micronutrient powder reduces stunting in full-term low-birth-weight infants receiving nutrition, health, and hygiene education: a 2 × 2 factorial, cluster-randomized trial in Bangladesh

BACKGROUND

The causes of stunting are complex but likely include prenatal effects, inadequate postnatal nutrient intake, and recurrent infections. Low-birth-weight (LBW) infants are at high risk of stunting. More than 25% of live births in low- and middle-income countries are at full term with low birth weight (FT-LBW). Evidence on the efficacy of specific interventions to enhance growth in this vulnerable group remains scant.

OBJECTIVE

We investigated the independent and combined effects of a directed use of a water-based hand sanitizer (HS) and a mineral- and vitamin-enhanced micronutrient powder (MNP) (22 minerals and vitamins) to prevent infections and improve nutrient intake to reduce stunting in FT-LBW infants.

DESIGN

The study was a prospective 2 × 2 factorial, cluster-randomized trial in 467 FT-LBW infants during 2 periods: from 0 to 5 mo postpartum (0-180 d postpartum) and from 6 to 12 mo postpartum (181-360 d postpartum) with the use of 48 clusters. All groups received the same general nutrition, health, and hygiene education (NHHE) at enrollment and throughout the 12 mo. Group assignments initially included the following 2 groups: no HS (control) group or HS from 0 to 5 mo postpartum. These assignments were followed by further divisions into the following 4 groups from 6 to 12 mo postpartum: 1) no HS and no MNP (control), 2) HS only, 3) MNP only, and 4) HS and MNP.

RESULTS

When delivered in combination with NHHE, the use of an HS showed no additional benefit in reducing indicators of infection in the first or second half of infancy or the likelihood of stunting at 12 mo postpartum. FT-LBW infants who received the MNP (with or without the HS) were significantly less likely to be stunted at 12 mo than were controls (OR: 0.35; 95% CI: 0.15, 0.84; P = 0.017).

CONCLUSIONS

The use of a mineral- and vitamin-enhanced MNP significantly reduced stunting in FT-LBW infants in this high-risk setting. The use of a water-based HS did not have an additive effect. This trial was registered at clinicaltrials.gov as NCT01455636.

Assessment of the needs of mothers and primary healthcare providers to support early childhood development in Egypt: a qualitative study

BACKGROUND

The early childhood period is considered the most important developmental phase in an individual's lifespan. However, it is not addressed in the Egyptian health system. We aimed to explore mothers' and healthcare providers' perceptions about early childhood development (ECD) and identify their needs to support ECD in Egypt.

METHODS

Focus group discussions with 79 mothers of children younger than 2 years old from different socio-economic backgrounds and residing in urban and rural areas and 26 primary healthcare providers were used to collect data. Emerging themes and subthemes were identified from the data analysis.

RESULTS

Urban and rural mothers in Egypt of all educational levels are not well prepared to support their children's early development, especially the cognitive and emotional aspects. Limited sources of information about ECD, the large families of rural women and an absence of developmental health services and family support were the most important factors that led to a neglect of mother-child communication and stimulation.

CONCLUSION

Raising community awareness and training primary healthcare providers to counsel mothers about ECD are important prerequisites for supporting ECD in Egypt. Rural and first-time mothers would be the most valuable starting point.

Acceptability of new formulations of corn-soy blends and lipid-based nutrient supplements in Province du Passoré, Burkina Faso

The objective of this study was to evaluate the acceptability of new formulations of six corn-soy blended flours (CSB) and six lipid-based nutrient supplements (LNS) with different quantities of milk and qualities of soy to be used for the treatment of moderate acute malnutrition (MAM). Furthermore, we wanted to explore the acceptability of foods currently used for the prevention and treatment of malnutrition in Burkina Faso to identify possible barriers that could affect the acceptability of the new formulations of supplementary foods. The study was carried out prior to a randomized controlled trial evaluating the effectiveness of these new formulations. The study involved an observed test-meal and a three-day take-home ration of the experimental food supplements to 6- to 30-months-old healthy children, followed by questionnaire-based interviews about the acceptability of these supplements. Interviews and focus group discussions were carried out to explore the acceptability of foods currently used for the prevention and treatment of malnutrition. The results suggest that both LNS and CSB products with different quantities of milk and qualities of soy are equally well accepted among healthy children in rural Burkina Faso based on general appreciation of the supplements and organoleptic properties. All experimental foods received good ratings and there was no significant difference between the foods. However, after the take-home ration, 58% of participants receiving CSB reported having left-overs at the end of the day compared to 37% (n = 33) of the participants receiving LNS (p = 0.004), suggesting that CSB was not as readily consumed as LNS. Yet, both CSB and LNS products were perceived as easy to administer and the frequency of feeding was estimated to be adequate. The study also found that similar foods, used for the prevention and treatment of malnutrition, were well appreciated in the study location. LNS were to a higher degree associated with medicine or foods with medicinal properties, but both LNS and CSB were perceived as beneficial to child health.

The influence of father's child feeding knowledge and practices on children's dietary diversity: a study in urban and rural districts of Northern Ethiopia, 2013

Infant and young child feeding has been recognised as an essential element to improve growth of children, especially in developing countries where malnutrition among children and its dire consequences are very prevalent. However, little attention has been paid on the influence of fathers on child feeding practices, although fathers are very important in raising well-adjusted, happy and successful children. Therefore, this study aimed to assess the influence of fathers' child feeding knowledge and practice on children's dietary diversity. A community-based comparative cross-sectional study was conducted among 850 eligible urban and rural households with children of 6-23 months. The father and mother of the child were interviewed on children's dietary diversity and fathers' knowledge and practice of child feeding. Nearly half (46%) of the children in the rural district did not meet the minimum dietary diversity, and in the urban district, the rate was even worse (72%). Grains were the common food group given to the children in both districts, whereas flesh food was the least commonly consumed food group. Additionally, low vitamin A-rich food and other fruit and vegetable consumption seem to be a problem in both districts. Almost all dimensions of fathers' knowledge and practice were significantly related to children's minimum dietary diversity; especially, fathers' knowledge of food groups was an important predictor (P-value < 0.001) in both districts. Interventions that focus on the fathers' knowledge of child feeding, especially about food groups, are recommended to improve children's dietary diversity in the study communities.

Promoting equity through integrated early child development and nutrition interventions

Sustainable development, a foundation of the post-2015 global agenda, depends on healthy and productive citizens. The origins of adult health begin early in life, stemming from genetic-environmental interactions that include adequate nutrition and opportunities for responsive learning. Inequities associated with inadequate nutrition and early learning opportunities can undermine children's health and development, thereby compromising their productivity and societal contributions. Transactional theory serves as a useful framework for examining the associations that link early child development and nutrition because it emphasizes the interplay that occurs between children and the environment, mediated through caregiver interactions. Although single interventions targeting early child development or nutrition can be effective, there is limited evidence on the development, implementation, evaluation, and scaling up of integrated interventions. This manuscript introduces a special edition of papers on six topics central to integrated child development/nutrition interventions: (1) review of integrated interventions; (2) methods and topics in designing integrated interventions; (3) economic considerations related to integrated interventions; (4) capacity-building considerations; (5) examples of integrated interventions; and (6) policy implications of integrated interventions. Ensuring the health and development of infants and young children through integrated child development/nutrition interventions promotes equity, a critical component of sustainable development.

Formative research methods for designing culturally appropriate, integrated child nutrition and development interventions: an overview

Nutritional and developmental insults in the first few years of life have profound public health implications, including substantial contributions to neonatal, infant, and early childhood morbidity and mortality, as well as longer term effects on cognitive development, school achievement, and worker productivity. Optimal development that can lead to the attainment of an individual's fullest potential, therefore, requires a combination of genetic capacity, adequate nutrition, psychosocial stimulation, and safe, clean physical environments. Researchers and policymakers have called for integrated child nutrition and development interventions for more than 20 years, yet there are only a handful of efficacy trials and even fewer examples of integrated interventions that have been taken to scale. While a critical component in the design of such interventions is formative research, there is a dearth of information in both the literature and policy arenas to guide this phase of the process. To move the field forward, this paper first provides an overview of formative research methods with a focus on qualitative inquiry, a description of the critical domains to be assessed (infant and young child feeding, responsive feeding, and child development), and currently available resources. Application of these methods is provided through a real-world case study--the design of an integrated nutrition and child development efficacy trial in Andhra Pradesh, India. Recommendations for next steps are discussed, the most important of which is the need for a comprehensive set of formative guidelines for designing locally tailored, culturally appropriate, integrated interventions.

Bridging immunity and lipid metabolism by gut microbiota

The human gut is a unique organ in which hundreds of different microbial species find their habitat and in which different host physiologic functions, such as digestion, nutrition, and immunity, coexist. Although all these players were studied separately for decades, recently, there has been an explosion of studies demonstrating the essential role for interactions between these components in gut function. Furthermore, new systems biology methods provide essential tools to study this complex system as a whole and to identify key elements that define the crosstalk between the gut microbiota, immunity, and metabolism. This review is devoted to several human diseases resulting from the disruption in this crosstalk, including immunodeficiency-associated and environmental enteropathies, celiac disease, inflammatory bowel disease, and obesity. We describe findings in experimental models of these diseases and in germ-free animals that help us understand the mechanisms and test new therapeutic strategies. We also discuss current challenges that the field is facing and propose that a new generation of antibiotics, prebiotics, and probiotics coupled with novel, systems biology-driven diagnostics will provide the basis for future personalized therapy.

Annual Research Review: Improved nutrition--pathway to resilience

BACKGROUND

Early child nutritional deficiencies are prevalent in low- and middle-countries with consequences linked not only to poor survival and growth, but also to poor development outcomes. Children in disadvantaged communities face multiple risks for nutritional deficiencies, yet some children may be less susceptible or may recover more quickly from malnutrition. A greater understanding is needed about factors which moderate the effects of nutrition-related risks and foster resilience to protect against or ameliorate poor development outcomes.

METHODS

A literature review was undertaken from August to December 2011 and updated in August 2012. Key word searches using terms Nutrition, Malnutrition, Child Development, Responsive Care, Stimulation, Low and Middle Income Countries and Resilience were undertaken using PubMed and Psychinfo.

RESULTS

Dietary adequacy is critical for growth and development, but current evidence indicates that nutrition supplementation alone is insufficient to foster resilience to protect against, mitigate, and recover from nutritional threats and to promote healthy development. The combination of nutrition interventions with stimulation and responsive care is necessary. Combined nutrition and psychosocial stimulation approaches can potentially work effectively together to promote protective factors and mitigate risks for poor cognitive, motor, social, and affective functioning helping children to adapt in times of adversity. However, there are gaps in our existing knowledge to combine nutrition and psychosocial stimulation interventions effectively and promote these interventions at scale.

CONCLUSIONS

Research needs to address barriers at the level of family, community, programme, and policy which have prevented thus far the uptake of combined nutrition and psychosocial intervention strategies. Further investigations are needed on how to provide support to caregivers, enabling them to implement appropriate care for feeding and stimulation. Finally, the effect of combined interventions on pathways of care and protective mediators that foster resilience need to be better understood to determine focus areas for content of combined intervention curricula which help families in high-risk settings.

Does combining infant stimulation with emergency feeding improve psychosocial outcomes for displaced mothers and babies? A controlled evaluation from northern Uganda

Combined psychosocial and nutrition interventions improve the development of infants. However, there is a paucity of studies examining the effectiveness of such interventions in humanitarian settings. This article examines the impact of combining a group-based psychosocial intervention with an existing emergency feeding program for internally displaced mothers in Northern Uganda. The intervention consisted of mother and baby group sessions and home visits for mothers attending 3 emergency feeding centers. Psychosocial outcomes were compared with a contrast group of mothers who received nutritional support alone. The outcomes investigated were infant stimulation and maternal mood. After controlling for the effects of interview site and baseline scores, mothers in the intervention group (n = 70) showed greater involvement with their babies, more availability of play materials, and less sadness and worry at follow-up in comparison to the contrast group (n = 77). The intervention was acceptable to the mothers and easily taught. A proportion of the mothers chose to continue the intervention spontaneously with other mothers in their neighbourhoods. Further research needs to be done to validate these preliminary findings and explore the longer term impact on child growth and intellectual development as well as maternal mood.

Breast-milk substitutes: a new old-threat for breastfeeding policy in developing countries. A case study in a traditionally high breastfeeding country

BACKGROUND

Developing countries with traditionally breastfeeding are now experiencing the increasing pressure of formula milk marketing. This may endanger lives and undermine the efforts of national policies in achieving the objectives of the Millennium Development Goals. We examined the use of, and factors for use, of all available breast-milk substitutes (BMS) in a country with a traditionally high rate of breastfeeding.

METHODS

Randomised multi-stage sampling surveys in 90 villages in 12/17 provinces in Laos.

PARTICIPANTS

1057 mothers with infants under 24 months of age.

TOOLS

50-query questionnaire and a poster of 22 BMS (8 canned or powdered milk; 6 non-dairy; 6 formulas; 2 non-formulas). OUTCOME MEASURES INCLUDED: prevalence of use and age of starting BMS in relation to socio-demographic characteristics and information sources, by univariate and multivariate analyses.

RESULTS

Of 1057 mothers: 72.5% currently breastfed; 25.4% gave BMS (10.6% infant formula); 19.6% gave BMS before 6 months of age (of them: 83% non-dairy or cereals; mean age: 2.9 months; 95% Confidence interval: 2.6-3.2). One formula and one non-formula product accounted for 85% of BMS. BMS were considered as milk by the majority of mothers. Thai TV was the main source of information on BMS for mothers. Lao Loum mothers (the main ethnic group) living in concrete houses with good sanitary conditions, were more likely than others to use BMS before 6 months (OR: 1.79, (1.15-2.78), p<0.009). Mothers who fed their infants colostrum at birth were less likely to use BMS before 6 months of age (OR: 0.63, (0.41-0.99), p = 0.04). Unemployed mothers living in rural areas were less likely to consider BMS better than breast milk.

CONCLUSION

In Laos, mothers with the highest socio-economic status are showing a tendency to give up breastfeeding. Successful educational strategies and advocacy measures should be urgently developed to promote and sustain breastfeeding in developing countries.

Postnatal depression and its effects on child development: a review of evidence from low- and middle-income countries

INTRODUCTION OR BACKGROUND

It is well established that postnatal depression (PND) is prevalent in high-income countries and is associated with negative personal, family and child developmental outcomes.

SOURCES OF DATA

Here, studies on the prevalence of maternal PND in low- and middle-income countries are reviewed and a geographical prevalence map is presented. The impact of PND upon child outcomes is also reviewed.

AREAS OF AGREEMENT

The available evidence suggests that rates of PND are substantial, and in many regions, are higher than those reported for high-income countries. An association between PND and adverse child developmental outcomes was identified in many of the countries examined.

AREAS OF CONTROVERSY

Significant heterogeneity in prevalence rates and impact on child outcomes across studies means that the true extent of the disease burden is still unclear.

AREAS TIMELY FOR DEVELOPING RESEARCH

Nonetheless, there is a compelling case for the implementation of interventions to reduce the impact of PND on the quality of the mother-infant relationship and improve child outcomes.

IV. Growth Failure in Institutionalized Children

Children within institutional care settings experience significant global growth suppression, which is more profound in children with a higher baseline risk of growth impairment (e.g., low birth weight [LBW] infants and children exposed to alcohol in utero). Nutritional insufficiencies as well as suppression of the growth hormone-insulin-like growth factor axis (GH-IGF-1) caused by social deprivation likely both contribute to the etiology of psychosocial growth failure within these settings. Their relative importance and the consequent clinical presentations probably relate to the age of the child. While catch-up growth in height and weight are rapid when children are placed in a more nurturing environment, many factors, particularly early progression through puberty, compromise final height. Potential for growth recovery is greatest in younger children and within more nurturing environments where catch-up in height and weight is positively correlated with caregiver sensitivity and positive regard. Growth recovery has wider implications for child well-being than size alone, because catch-up in height is a positive predictor of cognitive recovery as well. Even with growth recovery, persistent abnormalities of the hypothalamic-pituitary-adrenal system or the exacerbation of micronutrient deficiencies associated with robust catch-up growth during critical periods of development could potentially influence or be responsible for the cognitive, behavioral, and emotional sequelae of early childhood deprivation. Findings in growth-restricted infants and those children with psychosocial growth are similar, suggesting that children experiencing growth restriction within institutional settings may also share the risk of developing the metabolic syndrome in adulthood (obesity, Type 2 diabetes mellitus, hypertension, heart disease). Psychosocial deprivation within any care-giving environment during early life must be viewed with as much concern as any severely debilitating childhood disease.

Inequality in early childhood: risk and protective factors for early child development

Inequality between and within populations has origins in adverse early experiences. Developmental neuroscience shows how early biological and psychosocial experiences affect brain development. We previously identified inadequate cognitive stimulation, stunting, iodine deficiency, and iron-deficiency anaemia as key risks that prevent millions of young children from attaining their developmental potential. Recent research emphasises the importance of these risks, strengthens the evidence for other risk factors including intrauterine growth restriction, malaria, lead exposure, HIV infection, maternal depression, institutionalisation, and exposure to societal violence, and identifies protective factors such as breastfeeding and maternal education. Evidence on risks resulting from prenatal maternal nutrition, maternal stress, and families affected with HIV is emerging. Interventions are urgently needed to reduce children's risk exposure and to promote development in affected children. Our goal is to provide information to help the setting of priorities for early child development programmes and policies to benefit the world's poorest children and reduce persistent inequalities.

Fatores favoráveis à recuperação do quadro clínico de crianças anêmicas: um estudo exploratório

OBJETIVO: investigar a existência de aspectos do ambiente familiar de crianças anêmicas que possam ser considerados favoráveis à recuperação do quadro de anemia e ao desenvolvimento da linguagem. MÉTODOS: trata-se de um estudo de caso de crianças com anemia. As crianças (n = 11) foram submetidas anteriormente ao tratamento clínico e avaliação da linguagem. Após 12 meses, foram reavaliadas nos aspectos clínicos e da linguagem, acrescentando-se a investigação dos recursos do ambiente familiar. Deste grupo, foram selecionados três casos que refletem diferentes evoluções do quadro clínico da anemia e do desenvolvimento da linguagem, a fim de explorar as contribuições do ambiente familiar na melhora desses aspectos. RESULTADOS: a comparação das variáveis entre as crianças que obtiveram melhora ou não no tratamento medicamentoso mostra diferença estatisticamente nos valores de hemoglobina e tempo de aleitamento materno (p<0,05). A análise dos três casos revela que a situação ambiental pode ser agravante do quadro clínico da criança. CONCLUSÕES: a qualidade dos recursos domiciliares, o tempo de aleitamento materno e as práticas parentais em relação à criança podem ter contribuído para a adequada recuperação da criança nos aspectos focalizados.

Growth and associations between auxology, caregiving environment, and cognition in socially deprived Romanian children randomized to foster vs ongoing institutional care

OBJECTIVES

To determine effects of improved nurturing compared with institutional care on physical growth and to investigate the association between growth and cognitive development.

DESIGN

A randomized controlled trial beginning in infants (mean age, 21.0 months; range, 5-32 months), with follow-up at 30, 42, and 54 months of age.

SETTING

Institutionalized and community children in Bucharest, Romania.

PARTICIPANTS

One hundred thirty-six healthy institutionalized children from 6 orphanages and 72 typically developing, never-institutionalized children.

INTERVENTION

Institutionalized children were randomly assigned to receive foster care or institutional care as usual.

OUTCOME MEASURES

Auxology and measures of intelligence over time.

RESULTS

Growth in institutionalized children was compromised, particularly in infants weighing less than 2500 g at birth. Mean height and weight, though not head size, increased to near normal within 12 months in foster care. Significant independent predictors for greater catch-up in height and weight included age younger than 12 months at randomization, lower baseline z scores, and higher caregiving quality, particularly caregiver sensitivity and positive regard. Baseline developmental quotient, birth weight, and height catch-up were significant independent predictors of cognitive abilities at follow-up. Each incremental increase of 1 in standardized height scores between baseline and 42 months was associated with a mean increase of 12.6 points (SD, 4.7 points) in verbal IQ (P < .05).

CONCLUSIONS

Foster care had a significant effect on growth, particularly with early placement and high-quality care. Growth and IQ in low-birth-weight children are particularly vulnerable to social deprivation. Catch-up growth in height under more nurturing conditions is a useful indicator of caregiving quality and cognitive improvement.

Is undernutrition a risk factor for sensorineural hearing loss in early infancy?

The present cross-sectional study set out to determine the nutritional status of infants aged 0–3 months with the WHO Multicentre Growth Reference (WHO-MGR) and examine the relationship between undernutrition and congenital or early-onset sensorineural hearing loss (CESHL) rarely reported for developing countries. The nutritional status of all infants attending community-based clinics for routine Bacille de Calmette-Guérin (BCG) immunisation from July 2005 to December 2006 was determined by weight-for-age, weight-for-length and BMI-for-age based on the WHO-MGR. Hearing loss status was determined by tympanometry, auditory brainstem response (ABR) and visual response audiometry after a two-stage screening with transient evoked otoacoustic emissions and automated ABR. The relationship between nutritional status and CESHL were explored after adjusting for potentially confounding maternal and infant characteristics using multivariable logistic regression analyses. Of the 3386 infants who completed the hearing evaluation protocol, seventy-one were confirmed with hearing loss (>30 dB hearing level). More than one-third (37·9 %) of all infants and over half (54·9 %) of those with CESHL were undernourished by at least one measure of growth. Stunting (35·3 %) was the most prevalent nutritional deficit in infants with CESHL. In the final logistic model, infants with any undernourished physical state were significantly likely to have CESHL (OR 1·67; 95 % CI 1·03, 2·77) and of a severe-to-profound degree (OR 3·92; 95 % CI 1·38, 11·17) compared with infants without any undernourishment. Prospective studies to establish the full spectrum of the relationship between undernutrition and CESHL, particularly in resource-poor countries, are therefore warranted.

Undernourished children have different temperaments than better-nourished children in rural Bangladesh

Undernutrition in early childhood is associated with poor cognitive development and some changes in behavior. However, there is little information on their temperament. Our objective in this study was to determine whether undernourished children aged 6-24 mo had different temperament traits than better-nourished children. Two hundred and twelve undernourished children (weight for age < -2 Z-scores) attending community nutrition centers in 20 villages in rural Bangladesh and 108 better-nourished children (weight-for-age > or = -2 Z-scores) matched for age, sex, and village participated in the study. Temperament was assessed through an interviewer-administered maternal questionnaire consisting of 7 subscales: manageability, activity, emotionality, sociability, attention, soothability, and fear. After adjusting for significant covariates, the undernourished children were less sociable [regression coefficient (B) = -0.96; 95% CI = -0.04, -1.88], less attentive (B = -0.94; 95% CI = -0.19, -1.69), more fearful (B = 1.43; 95% CI = 2.44, 0.42), and had more negative emotionality (B = -1.08; 95% CI = 0.006, -2.16). In conclusion, these undernourished children had comprehensive differences in temperament traits, which may increase their risk of developing behavioral and mental health problems in later childhood.
