Emerging Evidence and Critical Issues with the Use of Single-Drop Capillary Blood for the Measurement of Hemoglobin Concentration in Population-Level Anemia Surveys.

Accurate and precise measurement of hemoglobin concentration is critical for reliable estimations of anemia prevalence at the population level. When systematic and/or random error are introduced in hemoglobin measurement, estimates of anemia prevalence might be significantly erroneous and, hence, limit their usefulness. For decades, single-drop capillary blood has been the most common blood source used for the measurement of hemoglobin concentration in surveys, especially in low-income and middle-income countries.

Towards Harmonized Adolescent Health Measurement: Assessing Alignment Between Current Recommendations and the Global Action for Measurement of Adolescent Health-Recommended Indicators.

Purpose: This study identified alignment of indicators across different initiatives and data collection instruments as a foundation for future harmonization of adolescent health measurement.

Methods: Using the Global Action for Measurement of Adolescent health (GAMA) recommended indicators as the basis for comparison, we conducted a desk review of 14 global-level initiatives, such as the Sustainable Development Goals and the Global Strategy for Women's, Children's and Adolescents' Health, and five multicountry survey programs, such as the Multiple Indicator Cluster Surveys and the Global school-based Student Health Survey. We identified initiative and survey indicators similar to a GAMA indicator, deconstructed indicators into standard elements to facilitate comparison, and assessed alignment to the corresponding GAMA indicator across each of the elements.

Critical assessment of the current indicator for antenatal iron-containing supplementation coverage: Insights from a mixed-methods study.

Daily consumption of iron-containing supplements is recommended for all pregnant women but there is no approved global standard indicator for assessing supplementation coverage. Furthermore, the validity of commonly used coverage indicators for iron-containing supplement consumption is questionable. The WHO-UNICEF Technical Expert Advisory Group on Nutrition Monitoring, and partners, have systematically worked to identify a feasible and valid indicator of iron-containing supplement coverage for reporting by countries.

Measuring coverage of infant and young child feeding counselling interventions: A framework and empirical considerations for survey question design.

Most countries implement nutrition counselling interventions as part of programmes to support breastfeeding and complementary feeding. However, data to track coverage of counselling interventions are rarely available. As a result, little is known about the coverage of counselling on infant and young child feeding (IYCF).

Prevalence thresholds for wasting, overweight and stunting in children under 5 years.

Objective: Prevalence ranges to classify levels of wasting and stunting have been used since the 1990s for global monitoring of malnutrition. Recent developments prompted a re-examination of existing ranges and development of new ones for childhood overweight. The present paper reports from the WHO-UNICEF Technical Expert Advisory Group on Nutrition Monitoring.

Factors influencing the uptake of a mass media intervention to improve child feeding in Bangladesh.

Mass media are increasingly used to deliver health messages to promote social and behaviour change, but there has been little evidence of mass media use for improving a set of child feeding practices, other than campaigns to promote breastfeeding. This study aimed to examine the factors influencing the uptake of infant and young child feeding messages promoted in TV spots that were launched and aired nationwide in Bangladesh. We conducted a mixed-methods study, using household surveys (n = 2,000) and semistructured interviews (n = 251) with mothers of children 0-23.

The Pathways from a Behavior Change Communication Intervention to Infant and Young Child Feeding in Bangladesh Are Mediated and Potentiated by Maternal Self-Efficacy.

Background: Although self-efficacy is a potential determinant of feeding and care behaviors, there is limited empirical analysis of the role of maternal self-efficacy in low- and middle-income countries. In the context of behavior change interventions (BCIs) addressing complementary feeding (CF), it is possible that maternal self-efficacy can mediate or enhance intervention impacts.

Objective: In the context of a BCI in Bangladesh, we studied the role of maternal self-efficacy for CF (MSE-CF) for 2 CF behaviors with the use of a theoretically grounded empirical model of determinants to illustrate the potential roles of MSE-CF.

Quality of nutrition services in primary health care facilities: Implications for integrating nutrition into the health system in Bangladesh.

Background: In 2011, the Bangladesh Government introduced the National Nutrition Services (NNS) by leveraging the existing health infrastructure to deliver nutrition services to pregnant woman and children. This study examined the quality of nutrition services provided during antenatal care (ANC) and management of sick children younger than five years.

Methods: Service delivery quality was assessed across three dimensions; structural readiness, process and outcome.

Large-Scale Behavior-Change Initiative for Infant and Young Child Feeding Advanced Language and Motor Development in a Cluster-Randomized Program Evaluation in Bangladesh.

Background: Promoting adequate nutrition through interventions to improve infant and young child feeding (IYCF) has the potential to contribute to child development.

Objective: We examined whether an intensive intervention package that was aimed at improving IYCF at scale through the Alive & Thrive initiative in Bangladesh also advanced language and gross motor development, and whether advancements in language and gross motor development were explained through improved complementary feeding.

Methods: A cluster-randomized design compared 2 intervention packages: intensive interpersonal counseling on IYCF, mass media campaign, and community mobilization (intensive) compared with usual nutrition counseling and mass media campaign (nonintensive).

Impacts on Breastfeeding Practices of At-Scale Strategies That Combine Intensive Interpersonal Counseling, Mass Media, and Community Mobilization: Results of Cluster-Randomized Program Evaluations in Bangladesh and Viet Nam.

Background: Despite recommendations supporting optimal breastfeeding, the number of women practicing exclusive breastfeeding (EBF) remains low, and few interventions have demonstrated implementation and impact at scale. Alive & Thrive was implemented over a period of 6 y (2009-2014) and aimed to improve breastfeeding practices through intensified interpersonal counseling (IPC), mass media (MM), and community mobilization (CM) intervention components delivered at scale in the context of policy advocacy (PA) in Bangladesh and Viet Nam. In Bangladesh, IPC was delivered through a large non-governmental health program; in Viet Nam, it was integrated into government health facilities.

Combining Intensive Counseling by Frontline Workers with a Nationwide Mass Media Campaign Has Large Differential Impacts on Complementary Feeding Practices but Not on Child Growth: Results of a Cluster-Randomized Program Evaluation in Bangladesh.

Background: Complementary feeding (CF) contributes to child growth and development, but few CF programs are delivered at scale. Alive & Thrive addressed this in Bangladesh through intensified interpersonal counseling (IPC), mass media (MM), and community mobilization (CM).

Objective: The objective was to evaluate the impact of providing IPC + MM + CM (intensive) compared with standard nutrition counseling + less intensive MM + CM (nonintensive) on CF practices and anthropometric measurements.

Breastfeeding and infant growth outcomes in the context of intensive peer counselling support in two communities in Bangladesh.

Background: Exclusive breastfeeding and growth faltering during infancy remain challenges in Bangladesh. The Training & Assistance for Health & Nutrition Foundation has been working to address this gap through community-based peer counsellors since 2000. In this paper, we assessed the programme's progress, particularly with respect to early initiation of breastfeeding and exclusive breastfeeding for normal birth weight, as well as for low birth weight (LBW) infants.

Learning how programs achieve their impact: embedding theory-driven process evaluation and other program learning mechanisms in alive & thrive.

Background: Traditionally, impact evaluations have focused primarily on answering what impact programs or interventions have, with less attention to how or why impacts are achieved, or not achieved. The Alive & Thrive initiative, a 6-year program that aims to improve infant and young child feeding (IYCF) practices and reduce stunting in Bangladesh, Ethiopia, and Vietnam, has a specific objective to generate learning on how to achieve and replicate Alive & Thrive's impact.

Objective: In Alive & Thrive, theory-driven process evaluation methods are the primary mechanism through which data are generated to address this objective.

Household food insecurity is associated with higher child undernutrition in Bangladesh, Ethiopia, and Vietnam, but the effect is not mediated by child dietary diversity.

Household food insecurity (HFI) is a recognized underlying determinant of child undernutrition, but evidence of associations between HFI and child undernutrition is mixed. The purpose of this study was to investigate if HFI is associated with undernutrition in children aged 6-59.9 mo in Bangladesh (n = 2356), Ethiopia (n = 3422), and Vietnam (n = 3075) and if child dietary diversity (DD) mediated this effect.

A program impact pathway analysis identifies critical steps in the implementation and utilization of a behavior change communication intervention promoting infant and child feeding practices in Bangladesh.

Mapping pathways of how interventions are implemented and utilized enables contextually grounded interpretation of results, differentiates poor design from poor implementation, and identifies factors that might influence the utilization of interventions. Few studies in nutrition have comprehensively examined the steps of implementation and utilization in behavior change communication (BCC) interventions, thus limiting the interpretation of variable impacts of BCC interventions. A program impact pathway (PIP) analysis was used to study a BCC intervention implemented in Bangladesh to improve infant and young child feeding (IYCF) practices.

Anaemia in infancy in rural Bangladesh: contribution of iron deficiency, infections and poor feeding practices.

Few data exist on the aetiology of anaemia and Fe deficiency (ID) during early infancy in South Asia. The present study aimed to determine the contribution of ID, infections and feeding practices to anaemia in Bangladeshi infants aged 6-11 months. Baseline data from 1600 infants recruited into a cluster-randomised trial testing the effectiveness of micronutrient powder sales by frontline health workers on the prevalence of anaemia were used.

Maternal and child dietary diversity are associated in Bangladesh, Vietnam, and Ethiopia.

Dietary diversity (DD) reflects micronutrient adequacy of the diet and is associated with better child growth. Emerging evidence suggests that maternal and child DD are associated. This could have measurement and programmatic implications.

Maternal mental health is associated with child undernutrition and illness in Bangladesh, Vietnam and Ethiopia.

Objective: We assessed associations of maternal common mental disorders (CMD) with undernutrition and two common illnesses in children aged 0-5 years.

Design: Cross-sectional survey. Maternal CMD was measured using the WHO Self-Reporting Questionnaire-20.

Pre- and postnatal arsenic exposure and body size to 2 years of age: a cohort study in rural Bangladesh.

Background: Exposure to arsenic via drinking water has been associated with adverse pregnancy outcomes and infant morbidity and mortality. Little is known, however, about the effects of arsenic on child growth.

Objective: We assessed potential effects of early-life arsenic exposure on weight and length of children from birth to 2 years of age.

Use of the new World Health Organization child growth standards to describe longitudinal growth of breastfed rural Bangladeshi infants and young children.

Background: Although the National Center for Health Statistics (NCHS) reference has been widely used, in 2006 the World Health Organization (WHO) released new standards for assessing growth of infants and children worldwide.

Objective: To assess and compare the growth of breastfed rural Bangladeshi infants and young children based on the new WHO child growth standards and the NCHS reference.

Methods: We followed 1343 children in the Maternal and Infant Nutrition Intervention in Matlab (MINIMat) study from birth to 24 months of age.

Household food security is associated with growth of infants and young children in rural Bangladesh.

Objective: Despite a strong relationship between household food security and the health and nutritional status of adults and older children, the association of household food security with the growth of infants and young children has not been adequately studied, particularly in developing countries. We examined the association between household food security and subsequent growth of infants and young children in rural Bangladesh.

Design: We followed 1343 children from birth to 24 months of age who were born in the Maternal and Infant Nutrition Intervention in Matlab (MINIMat) study in rural Bangladesh.

Household food security is associated with infant feeding practices in rural Bangladesh.

Although household food security (HHFS) has been shown to affect diet, nutrition, and health of adults and also learning in children, no study has examined associations with infant feeding practices (IFP). We studied 1343 infants born between May 2002 and December 2003 in the Maternal and Infant Nutrition Intervention in Matlab study to investigate the effect of HHFS on IFP in rural Bangladesh. We measured HHFS using a previously developed 11-item scale.

Appropriate infant feeding practices result in better growth of infants and young children in rural Bangladesh.

Background: The World Health Organization and the United Nations International Children's Emergency Fund recommend a global strategy for feeding infants and young children for proper nutrition and health.

Objective: We evaluated the effects of following current infant feeding recommendations on the growth of infants and young children in rural Bangladesh.

Design: The prospective cohort study involved 1343 infants with monthly measurements on infant feeding practices (IFPs) and anthropometry at 17 occasions from birth to 24 mo of age to assess the main outcomes of weight, length, anthropometric indexes, and undernutrition.

Adopting integrated management of childhood illness module at local level in Bangladesh: implications for recurrent costs.

This study estimated the recurrent cost implications of adopting Integrated Management of Childhood Illness (IMCI) at the first-level healthcare facilities in Bangladesh. Data on illnesses of children who sought care either from community health workers (CHWs) or from paramedics over a four-month period were collected in a rural community. A total of 5,505 children sought care.
