RESUMO

In-home fortification of infants with micronutrient powders (MNPs) containing 12.5 mg iron may increase morbidity from infections; therefore, an efficacious low-dose iron-containing MNP might be advantageous. Effects of iron-containing MNPs on infant growth are unclear. We assessed the efficacy of a low-iron MNP on iron status and growth and monitored safety in a randomised, controlled, double-blind 1-year trial in 6-month-old infants (n = 287) consuming daily a maize porridge fortified with either a MNP including 2.5 mg iron as NaFeEDTA (MNP + Fe) or the same MNP without iron (MNP - Fe). At baseline, after 6 and 12 months, we determined haemoglobin (Hb), iron status [serum ferritin (SF), soluble transferrin receptor (sTfR) and zinc protoporphyrin (ZPP)], inflammation [C-reactive protein (CRP)] and anthropometrics. We investigated safety using weekly morbidity questionnaires asking for diarrhoea, cough, flu, bloody or mucus-containing stool and dyspnoea, and recorded any other illness. Furthermore, feeding history and compliance were assessed weekly. At baseline, 71% of the infants were anaemic and 22% iron deficient; prevalence of inflammation was high (31% had an elevated CRP). Over the 1 year, Hb increased and SF decreased in both groups, without significant treatment effects of the iron fortification. At end point, the weight of infants consuming MNP + Fe was greater than in the MNP - Fe group (9.9 vs. 9.5 kg, P = 0.038). Mothers of infants in the MNP + Fe group reported more infant days spent with cough (P = 0.003) and dyspnoea (P = 0.0002); there were no significant differences on any other of the weekly morbidity measures. In this study, low-dose iron-containing MNP did not improve infant's iron status or reduce anaemia prevalence, likely because absorption was inadequate due to the high prevalence of infections and the low-iron dose.

RESUMO

Through a systematic reflection on the journey that transformed traditional state-run baby homes in Tajikistan from closed institutions into community-oriented Family and Child Support Centres (FCSC) we reveal key moments of change. This review describes how community consultation with local participants in a development project shifted responsibility and accountability from international to local ownership and how distributed leadership contributes to the decolonisation of social services. Based on these interviews we ask, 'How do the innovations of a social development project become a fixed part of normal local social, cultural and political life; and, how do we know when a new normal is self-sustaining at a local level?' This analysis builds on a network-mapping tool previously described in this journal. Our interviews show that each participant has taken a non-linear journey, building on the networks previously described, under the influence of activities and discussions that emerged throughout the project. We consider how a monitoring, evaluation, and learning process should be responsive over time to these influences, rather than be set at the start of the project. Using the themes that emerge from participants' journeys, we apply a 'measurement for change' (M4C) approach that integrates Monitoring, Evaluation and Learning (MEL) into decision-making. The journey framework applied represents a systematic application of the M4C approach that gives us insight into where local ownership is responsible for the sustainable management of the intervention, and where continued partnership will further strengthen impact and accountability. The exercise has provided evidence of progress towards decolonisation and of the centring of local priorities in MEL and implementation processes.

RESUMO

Background: Effective and real-time data analytics plays an essential role in understanding gaps and improving the quality and coverage of complex public health interventions. Studies of public health information systems identify problems with data quality, such as incomplete records and untimely reporting. Effective data collection and real-time analysis systems for rapid-cycle learning are necessary to monitor public health programs and take timely evidence-based decisions. Early childhood development (ECD) programs are very diverse. Rapid-cycle evaluation and learning (REAL) guides the implementation process of such complex interventions in real time. Stepping stones was one such early childhood development program implemented in Central India. Objective: The objective was to improve the delivery of complex, integrated public health interventions for early childhood development in remote areas of rural India. Methodology: The program was developed according to the principles of inclusion and community-centeredness, which can be tested quickly and iteratively. To enhance the decision-making process and improve delivery and coverage, the core team implemented an information system for rapid-cycle learning. We developed performance indicators and a performance measurement matrix after defining the specific needs. Following that, we trained staff to collect complete data using electronic data collection tools and transfer it the same day to the server for quality review and further analysis. A variety of data/information was triangulated to address the gaps in intervention delivery, and those decisions were subsequently implemented. Results: We observed that the quality of data collection improved, and errors were reduced by 50% in the third quarter. The quality of the narrative was also enhanced; it became more elaborate and reflective. Sharing their field output in meetings and improving the quality of the narrative enhanced the self-reflection skills of field staff and consequently improved the quality of the intervention delivery. Refresher training and mentoring by supervisors helped to improve the data quality over time. Conclusion: Rapid-cycle evaluation and learning (REAL) can be implemented in resource-limited settings to improve the quality and coverage of integrated intervention in early childhood. It nurtures a reinforcing ecosystem that integrates providers, community, and family perspectives and guides interactions among stakeholders by integrating data from all available sources.

RESUMO

Background: To promote early childhood development (ECD), we require information not only on what needs to be addressed and on what effects can be achieved but also on effective delivery methods that can be adapted to local context. We describe design, implementation, and evaluation of a complex intervention to strengthen nurturing environment for young children. Methods: Study participants were pregnant women and their children from birth to 2 years. We used design and redesign, implementation, and evaluation approaches for the study. We co-created curriculum and delivery plan with stakeholders, based on the theoretical framework, findings from formative research, and our preliminary work. We recruited 656 pregnant women and newborns, 326 (49.69%) from intervention and 330 (50.30%) from the control group. We conducted a cluster randomized controlled trial to evaluate the program's effectiveness. The outcomes of children were assessed at 12 and 24 months. Findings: At recruitment, study participants from both the study arms were similar in sociodemographic characteristics. We conducted 6,665 home visits, 25 toy-making workshops, and 65 caregiver-meetings. The initial examination of program data revealed gaps in quality and coverage of interventions. The intervention was redesigned based on feedback from stakeholders in community meetings. At recruitment, participants in both study groups had similar socio-demographics. We conducted 6,665 home visits, 25 toy workshops, and 65 caregiver meetings. Initial program data showed intervention quality and coverage gaps, leading to a redesign program based on community and stakeholder feedback. Post-re-designing, session quality improved, with program coverage rising from 32 to 98%. Male participation in home visits increased from 4.3 to 32.65%, and data errors reduced from 270 to 140 per month on average. At 24 months, program showed moderate-mild impact on ECD - cognitive (0.31, 95%CI: 0.13-0.48), language (0.2, 95%CI: 0.01-0.39), and socioemotional-development (0.19, 95%CI: 0.01-0.37), moderate effect on home-environment and mother-child interaction. 96% of women initiated breastfeed within one-hour of delivery, and exclusive-breastfeeding rate of 89.80%. Interpretations: The study provides an evidence-based community centered ECD curriculum and implementation strategies to enhance service providers, and caregivers' knowledge and skills for promoting ECD in low-resource settings with the potential to scale within existing Government Program. Funding: The trial was funded by the Saving Brains Round 5 Initiative of Grand Challenges Canada (Grant no. SB-1707-05084), and we are grateful for their ongoing support through online sessions and orientation workshops. The trial was also supported by the Indian Council of Medical Research (File No: 5/7/1693/CH/Adhoc/RBMCH-2020).

RESUMO

The aims of this study were to record behavioral problems in children with epilepsy (CWE), compare the prevalence with that reported among healthy children without epilepsy, and investigate the risk factors. A child behavioral questionnaire for parents comprising 15 items was administered to the main caregiver of 108 CWE and 108 controls matched for age in Kilifi, Kenya. CWE had a higher mean score for reported behavioral problems than controls (6.9 vs 4.9, t=4.7, P<0.001). CWE with active epilepsy also recorded more behavioral problems than those with inactive epilepsy (8.2 vs 6.2, t=-2.9, P=0.005). A significantly greater proportion of CWE (49% vs 26% of controls) were reported to have behavioral problems. Active epilepsy, cognitive impairment, and focal seizures were the most significant independent covariates of behavioral problems. Behavioral problems in African CWE are common and need to be taken into consideration in planning comprehensive clinical services in this region.

RESUMO

INTRODUCTION: A minority of births in sub-Saharan African regions are conducted with the supervision of skilled birth attendants. With among the highest world-wide maternal mortality ratios and the majority of the deaths being associated with a lack of trained supervision at delivery, changing delivery practices is a major priority in this world region. This study identified attitudes to and beliefs about the uptake of hospital services for birthing. METHODS: Data were gathered using a combination of individual interviews and group discussions. Twelve discussion groups were held with participants who included hospital staff and general community members (36 males and 54 females). In addition, individual interviews were carried out with 26 mothers who chose not to deliver their babies in hospital. RESULTS: Qualitative analysis identified a number of barriers to seeking skilled attendants at birth including: lack of resources (monetary, transport and access), customer care (lack of partnership between mother and health professional), and knowledge and beliefs (lack of knowledge about pregnancy and maternal health). CONCLUSIONS: The community must be better informed about the costs and benefits of hospital deliveries, while medical services must be more sensitive to community needs and preferences. These findings prompted the initiation of consultation groups on health and maternal issues between health service providers and community organisations.

RESUMO

The study examines the relationship between orphanhood status and nutritional status and food security among children living in the rapidly growing and uniquely vulnerable slum settlements in Nairobi, Kenya. The study was conducted between January and June 2007 among children aged 6-14 years, living in informal settlements of Nairobi, Kenya. Anthropometric measurements were taken using standard procedures and z scores generated using the NCHS/WHO reference. Data on food security were collected through separate interviews with children and their caregivers, and used to generate a composite food security score. Multiple regression analysis was done to determine factors related to vulnerability with regards to food security and nutritional outcomes. The results show that orphans were more vulnerable to food insecurity than non-orphans and that paternal orphans were the most vulnerable orphan group. However, these effects were not significant for nutritional status, which measures long-term food deficiencies. The results also show that the most vulnerable children are boys, those living in households with lowest socioeconomic status, with many dependants, and female-headed and headed by adults with low human capital (low education). This study provides useful insights to inform policies and practice to identify target groups and intervention programs to improve the welfare of orphans and vulnerable children living in urban poor communities.

RESUMO

Measurement for Change proposes an integration of monitoring, evaluation, and learning into decision-making systems that support sustainable transition of interventions to scale. It was developed using a cyclical, interactive 1-year dialogue between early childhood development (ECD) practitioners and academics from across the globe. Details are presented in Krapels et al. (1) as part of this special issue in Frontiers. In this paper, we trace the developments that inspired Measurement for Change and the novel ways in which the approach and the special issue was developed. The experience, and the reflections on this experience, are intended to inform those implementing initiatives that similarly seek to integrate practitioner- and academic experiences in support of sustainable transitions of interventions to scale.

RESUMO

BACKGROUND: Seizures are common in children admitted with severe falciparum malaria and are associated with neuro-cognitive impairments. Prolonged febrile seizures are associated with hippocampal damage and impaired memory. It was hypothesized that severe malaria causes impaired everyday memory which may be associated with hippocampal damage. METHODS: An everyday memory battery was administered on 152 children with cerebral malaria (CM) (mean age, 7 y 4 months [SD 13 months]; 77 males) 156 children (mean age, 7 y 4 months [SD, 14 months]; 72 males) with malaria plus complex seizures (MS) and 179 children (mean age, 7 y 6 months [SD, 13 months]; 93 males) unexposed to either condition. RESULTS: CM was associated with poorer everyday memory [95% CI, -2.46 to -0.36, p = 0.004] but not MS [95% CI, -0.91 to 1.16, p = 1.00] compared to unexposed children. Children with exposure to CM performed more poorly in recall [95% CI, -0.79 to -0.04, p = 0.024] and recognition subtests [95% CI, -0.90 to -0.17, p = 0.001] but not in prospective memory tests compared to controls. The health factors that predicted impaired everyday memory outcome in children with exposure to CM was profound coma [95% CI, 0.02 to 0.88, p = 0.037] and multiple episodes of hypoglycaemia [95% CI, 0.05 to 0.78, p = 0.020], but not seizures. DISCUSSION: The findings show that exposure to CM was associated with a specific impairment of everyday memory. Seizures commonly observed in severe malaria may not have a causal relationship with poor outcome, but rather be associated with profound coma and repeated metabolic insults (multi-hypoglycaemia) that are strongly associated with impaired everyday memory.

RESUMO

The dearth of locally developed measures of language makes it difficult to detect language and communication problems among school-age children in sub-Saharan African settings. We sought to describe variability in vocabulary acquisition as an important element of global cognitive functioning. Our primary aims were to establish the psychometric properties of an expressive vocabulary measure, examine sources of variability, and investigate the measure's associations with non-verbal reasoning and educational achievement. The study included 308 boys and girls living in a predominantly rural district in Kenya. The developed measure, the Kilifi Naming Test (KNT), had excellent reliability and acceptable convergent validity. However, concurrent validity was not adequately demonstrated. In the final regression model, significant effects of schooling and area of residence were recorded. Contextual factors should be taken into account in the interpretation of test scores. There is need for future studies to explore the concurrent validity of the KNT further.

RESUMO

BACKGROUND: Minimal data exist related to neurodevelopment after in utero exposure to Efavirenz (EFV). We sought to compare neurodevelopmental outcomes in HIV-exposed/uninfected (HEU) children with in utero exposure to EFV-based triple antiretroviral treatment (ART) versus non-EFV-based ART, and to examine whether timing of initial EFV exposure is associated with neurodevelopment deficits. METHODS: Women living with HIV who had received EFV-based ART during pregnancy and whose HEU newborn participated in a prior study were reconsented for their HEU toddler to undergo neurodevelopmental testing at 24 months old. We administered the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), Developmental Milestones Checklist (DMC) and Profile of Social Emotional Development (PSED). We compared outcomes to previously-collected data from a cohort of 24-month-old HEU children with in utero exposure to non-EFV-based ART. Adjusted general linear models were used to compare mean outcomes. RESULTS: Our analysis included 493 HEU children (126 EFV-exposed, 367 EFV-unexposed). Adjusted mean scores for the EFV-exposed group were worse than the EFV-unexposed group on BSID-III Receptive Language (adjusted means = 21.5 vs. 22.5, P = 0.05), DMC Locomotor (30.7 vs. 32.0, P < 0.01) and Fine Motor scales (17.8 vs. 19.2, P < 0.01); and PSED (11.7 vs. 9.9, P = 0.02); but better on the DMC Language scale (17.6 vs. 16.5, P = 0.01). Earlier (vs. later) EFV exposure was associated with worse scores on the BSID-III Receptive Language scale (20.7 vs. 22.2, P = 0.02). CONCLUSIONS: HEU children exposed in utero to EFV-based ART may be at higher risk for neurodevelopmental and social-emotional deficits than HEU children exposed to non-EFV-based ART.

RESUMO

There are a number of pathways, both direct and indirect, through which malaria infection could impact the course of child development, causing impairment and disability and adding to the burden of malaria. We present an overview of relevant studies that illustrate these pathways, updating the evidence previously presented. We conclude that before the mechanisms and numbers of affected children can be adequately defined, a wider range of potential pathways to impaired development need to be investigated. Only then can the calculation of the burden be evidence-based, rather than merely speculative. Priorities for future research are described. The calculation of the impact of malaria on child development also requires a degree of uniformity in the definition of outcome across studies. This is currently lacking, and suggestions are made for a common approach to the reporting of results.

RESUMO

Few investigations have examined the specificity of sequelae of very low birth weight (VLBW, <1500 g) or sources of variability in outcome. To better understand the nature and determinants of outcome, we assessed neuropsychological and achievement skills at mean age 11 years in 62 children with <750 g birth weight, 54 with 750-1499 g birth weight, and 66 term-born controls. Distinct cognitive constructs were identified by factor analysis, and the three birthweight groups were compared on these constructs and on composite measures of achievement. Although the group with <750 g birth weight performed less well on all tests than term-born controls, group differences in a perceptual planning factor and in mathematics remained even when IQ was controlled, and deficits were more pronounced in mathematics than in reading. Results from structural equation modeling were consistent with the hypothesis that neuropsychological skills mediated the relationship between birth weight and achievement. The findings confirm the differential deficit hypothesis, support the need to consider multiple sources of variability in VLBW outcomes, and highlight the importance of neuropsychological constructs in developing an explanatory framework.

RESUMO

This study investigated the psychometric properties of a number of neuropsychological tests adapted for use in sub-Saharan Africa. A total of 308 school-age children in a predominantly rural community completed the tests. These tests were developed to assess skills similar to those measured by assessments of cognitive development published for use in Western contexts. Culturally appropriate adaptations were made to enhance within-population variability. Internal consistency ranged from .70 to .84. Scores on individual tests were related to various background factors at the level of the child, household, and neighborhood. School experience was the most consistent predictor of outcome, accounting for up to 22.9% of the variance observed. Significant associations were identified to determine salient background characteristics that should be taken into account when measuring the discrete effects of disease exposure in similar sociocultural and economic settings.

RESUMO

BACKGROUND: Physical activity is a key component of exploration and development. Poor motor proficiency, by limiting participation in physical and social activities, can therefore contribute to poor psychological and social development. The current study examined the correlates of motor performance in a setting where no locally validated measures of motor skills previously existed. The development of an appropriate assessment schedule is important to avoid the potential misclassification of children's motor performance. METHODS: A cross-sectional study was conducted among a predominantly rural population. Boys (N = 148) and girls (N = 160) aged between 8 and 11 years were randomly selected from five schools within Kilifi District in Kenya. Four tests of static and dynamic balance and four tests of motor coordination and manual dexterity were developed through a 4-step systematic adaptation procedure. Independent samples t-tests, correlational, univariate and regression analyses were applied to examine associations between background variables and motor scores. RESULTS: The battery of tests demonstrated acceptable reliability and validity. Variability in motor performance was significantly associated with a number of background characteristics measured at the child, (gender, nutritional status and school exposure) household (household resources) and neighbourhood levels (area of residence). The strongest effect sizes were related to nutritional status and school exposure. CONCLUSIONS: The current study provides preliminary evidence of motor performance from a typically developing rural population within an age range that has not been previously studied. As well as being culturally appropriate, the developed tests were reliable, valid and sensitive to biological and environmental correlates. Further, the use of composite scores seems to strengthen the magnitude of differences seen among groups.

RESUMO

Hepcidin regulation by competing stimuli such as infection and iron deficiency has not been studied in infants and it's yet unknown whether hepcidin regulatory pathways are fully functional in infants. In this cross-sectional study including 339 Kenyan infants aged 6.0±1.1 months (mean±SD), we assessed serum hepcidin-25, biomarkers of iron status and inflammation, and fecal calprotectin. Prevalence of inflammation, anemia, and iron deficiency was 31%, 71%, 26%, respectively. Geometric mean (±SD) serum hepcidin was 6.0 (±3.4) ng/mL, and was significantly lower in males than females. Inflammation (C-reactive protein and interleukin-6) and iron status (serum ferritin, zinc protoporphyrin and soluble transferrin receptor) were significant predictors of serum hepcidin, explaining nearly 60% of its variance. There were small, but significant differences in serum hepcidin comparing iron deficient anemic (IDA) infants without inflammation to iron-deficient anemic infants with inflammation (1.2 (±4.9) vs. 3.4 (±4.9) ng/mL; P<0.001). Fecal calprotectin correlated with blood/mucus in the stool but not with hepcidin. Similarly, the gut-linked cytokines IL-12 and IL-17 did not correlate with hepcidin. We conclude that hepcidin regulatory pathways are already functional in infancy, but serum hepcidin alone may not clearly discriminate between iron-deficient anemic infants with and without infection. We propose gender-specific reference values for serum hepcidin in iron-replete infants without inflammation.

RESUMO

The ability to measure neuropsychological outcomes in a comparable manner in different cultural groups is important if studies conducted in geographically diverse regions are to advance knowledge of disease effects and moderating influences. The purpose of this study was to evaluate the application of neuropsychological test procedures developed for use in North America and Europe to children in a rural region of Kenya. Our specific aim was to determine if these methods could be adapted to a non-Western culture in a manner that would preserve test reliability and validity. Procedural modifications yielded reliable tests that were sensitive to both the sequelae of cerebral malaria and to children's social and school backgrounds. Results suggest that adaptations of existing tests can be made in such a way as to preserve their utility in measuring the cross-cultural sequelae of childhood neurological diseases.
