Information Diffusion and Social Norms Are Associated with Infant and Young Child Feeding Practices in Bangladesh

Incremental financial costs of strengthening large-scale child nutrition programs in Bangladesh, Ethiopia, and Vietnam: retrospective expenditure analysis

BACKGROUND

Inattention to young child growth and development in a transitioning global environment can undermine the foundation of human capital and future progress. Diets that provide adequate energy and nutrients are critical for children's physical and cognitive development from 6 to 23.9 months of age and beyond. Still, over 70% of young children do not receive foods with sufficient nutrition particularly in low-and-middle income countries. Program evaluations have documented the effectiveness of large-scale behavior change interventions to improve children's diets, but the budgetary implications of programs are not known. This paper provides the incremental financial costs of strengthening three large-scale programs based on expenditure records from Bangladesh, Ethiopia, and Vietnam.

RESULTS

The programs reached between one and 2.5 million mothers and children annually per country at unit costs of between $0.9 to $1.6 per mother and child reached. An additional 0.7 to 1.6 million people who were influential in supporting mothers and achieving scale were also engaged. The largest cost component was counselling of mothers. Rigorous external impact evaluations showed that over 434,500 children benefited annually from consuming a minimum acceptable diet in all countries combined, at an annual cost per country of $6.3 to $34.7 per child benefited.

CONCLUSIONS

Large scale programs to improve young children's nutrition can be affordable for low- and middle-income countries. The study provides the incremental costs of selectively strengthening key program components in diverse settings with lessons for future budgeting. The costs of treating a malnourished child are several-fold higher than prevention through improved improving young children's dietary practices. Differences across countries in program models, coverage, costs, and outcomes suggest that countries need a minimum investment of resources for strengthening high-reach service delivery and communication channels and engaging relevant behavioral levers and community support for mothers to achieve impact at scale.

Gendered Social Norms, Exceptions, and Sanctions: Implications for Maternal, Infant, and Young Child Nutrition in Nigeria

Background

Nigerian pregnant and lactating women continue to experience high rates of malnutrition and Nigerian women experience long-term discrimination in the allocation and control of productive resources. Nigeria has policies and a governance architecture in place to advance nutrition, but these commitments lack recognition of how gender equity and nutrition are interwoven.

Objective

To address this gap, this study sought to identify and analyze the influence of gender dynamics and gender norms on nutrition and health-related practices in Nigeria.

Methods

This study used a combination of qualitative participatory activities and participant observation and questions to elicit information about the root causes of maternal, infant, and young child nutrition (MIYCN) and health concerns and typical nutrition and health practices in communities located across each of Nigeria's 6 geopolitical zones. This analysis was informed by social norms theory and sought evidence of gender norms, as well as related social sanctions and norms exceptions.

Results

Analysis of discussions with 503 participating men and women identified 3 overarching gender meta-norms that dictate women's mobility, gendered delineation of household tasks, and gendered decision-making and, therefore, in turn influence women's and men's engagement in recommended MIYCN behaviors such as involvement in production and purchasing of nutritious foods and seeking healthcare and nutrition counseling. Participants also described strong traditional gender ideologies and sanctions that uphold these restrictive norms. Encouragingly, participants described some exceptions to norms, which could indicate changing gender norms.

Conclusions

Nigeria currently has one of the highest rates of acute food and nutrition insecurity in Africa and contends with persistent gender inequalities. Interventions are needed that more explicitly tackle the links between gender inequality and nutrition. This analysis revealed gender meta-norms, and related sanctions and exceptions that affect multiple MIYCN behaviors and offer potential entry points for community engagement, programming, and policy around these issues.

How Do Social and Behavioral Change Interventions Respond to Social Norms to Improve Women's Diets in Low- and Middle-Income Countries? A Scoping Review

Healthy dietary practices are highly influenced by social norms, the widely-held expectations about the behaviors that are appropriate or typical within a given group. However, many nutrition programs designed to reduce women's undernutrition in low- and middle-income countries do not address the influence of social and gender norms in their interventions, and therefore, there is limited information about how norms-responsive interventions have been designed and implemented. The objective of this scoping review was to identify and describe social and behavioral change interventions designed to improve women's dietary practices and nutritional intake that integrate the influence of social and gender norms. We systematically searched 4 databases (Scopus, Web of Science, PubMed, and CINAHL) for peer-reviewed articles describing design, implementation, and/or assessment of nutrition interventions in low- or middle-income countries. Results are reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our review identified 27 articles from 25 projects or research studies that addressed social or gender norms related to women's dietary practices. The majority focused on the pregnancy and lactation periods, and a few aimed to reach all women of reproductive age. Interventions most often endeavored to shift norms through multiple activities, channels, and platforms, aiming to reach not only the primary participants but also influencers and reference groups. Intervention approaches ranged from home visits and support groups to engage influential family members to community-level outreach with opinion leaders such as religious leaders, health care workers, and peer change agents. Most interventions were delivered through the health sector or were community-based, with some nutrition-sensitive agriculture interventions. There is increasing, although still limited, integration of social and gender norms perspectives in the design, implementation, and assessment of interventions to improve women's diets. This comprehensive review summarizes influential norms and intervention approaches, an important step toward enhancing the effectiveness of social and behavioral change interventions by addressing nutrition-relevant norms. This study was registered at Open Science Framework as JSBF7.

Coproduced, arts interventions for nurturing care (0-5 years) in low-income and middle-income countries (LMICs): a realist review

OBJECTIVES

Community-based arts interventions have the potential to support contextually relevant nurturing care programmes and policies that adapt to different settings. Understanding the distinctive features of using the arts in local, culturally specific ways in low/middle-income countries (LMICs); how this varies by context; and gaining a better understanding of the perspectives on desirable outcomes for communities is important evidence that this review generates.

DESIGN

We conducted a realist review of papers that covered outcomes related to child health or development (0-5 years) AND arts-based approaches AND community-based, participatory approaches AND based in LMICs using a range of databases and other networks. A coding framework was developed covering context, intervention, outcomes, mechanisms, study, sustainability, transferability and scalability.

RESULTS

The included papers reported 18 unique interventions. Interventions covered 14 countries, with evidence lacking for South America, Arab countries and parts of Africa. Lead authors came from mostly clinical science-based disciplines and from institutions in a different country to the country/countries studied. Intended outcomes from interventions included clinical, health systems/organisation, changes in practices/behaviours/knowledge/attitudes, and wider social and educational goals. We identified three demi-regularities (semi-predictable patterns or pathways of programme functioning): participatory design based on valuing different sources of expertise; dynamic adaptation of intervention to context; and community participation in arts-based approaches.

CONCLUSIONS

Our findings suggest that arts-based, nurturing care interventions have greater potential when they include local knowledge, embed into existing infrastructures and there is a clear plan for ongoing resourcing of the intervention. Studies with better documentation of the lessons learnt, regarding the intervention delivery process and the power dynamics involved, are needed to better understand what works, for whom and in which contexts.

Mothers' knowledge and practices on breastfeeding and complementary feeding in an urban slum area and rural area in Kenya: A cross-sectional interview study

Maternal breastfeeding and complementary feeding knowledge is an important determinant of childrens' long-term health and development. This study aims to account for associations between knowledge and practices in Kenya and report the food consumption of children from birth to 18 months. In 2015 mother-child pairs were recruited from Mother-and-Child Health Centers; 415 in an urban slum in Nairobi and 364 in rural Machakos. Knowledge and practice scores were calculated from questionnaire variables and 24-h food frequency questionnaire. The associations of knowledge and practices were studied with regression analysis. Breastfeeding knowledge (Nairobi 6.3/9, Machakos 5.9/9) and practices (Nairobi 7.5/8, Machakos 7.2/8) were good in both areas. Complementary feeding knowledge was not as good (Nairobi 7.5/14, Machakos 7.1/14). Minimum meal frequency was reached by almost 80% of the children but dietary diversity was low (Nairobi 2.7 [SD 1.4], Machakos 2.4. [SD 1.3]). Only 27% of children in Nairobi and 13% in Machakos were fed a minimum acceptable diet. The complementary feeding knowledge score was associated only with minimum dietary diversity in Nairobi (OR: 1.29; 95% CI: 1.105-1.514). Infant and young child feeding knowledge and practices were on a similar level in both areas. Future interventions should focus on improving dietary diversity.

Trends and determinants of early initiation of breastfeeding in Indonesia: A multivariate decomposition analysis

BACKGROUND

Early initiation of breastfeeding (EIBF) is key to reducing neonatal morbidity and mortality, however, little is known about the determinants of the trends of EIBF prevalence in Indonesia. This study aims to assess the contributing factors to the changes in the prevalence of EIBF between 2007 and 2017.

METHODS

We analysed data from the 2007, 2012, and 2017 Indonesia Demographic and Health Surveys to estimate the trends in EIBF. A multivariate logistic decomposition model was fitted to examine variables associated with changes in the percentage of EIBF from 2007 to 2017. The contributing factors to changes in EIBF prevalence were categorized into either compositional or behavioural changes, with each of them divided into portions or percentages of contribution (pct) of the independent variables. The former refers to the changes in the distribution of samples, while the latter refers to the changes in the behavioural responses toward EIBF in both surveys. All analyses accounted for the complex study design and potential confounding factors.

RESULTS

An increase in the prevalence of EIBF from 49.9% to 56.5% was recorded between 2012 and 2017, with an overall increase of 16.9 percentage points from 2007 to 2017. At the aggregate level, the compositional differences did not significantly contribute to the changes in the percentage of EIBF, while 98.3pct (p < 0.001) was associated with changes in mothers' behavioural response towards EIBF. The composition changes in the geographical region of Sumatra, and caesarean delivery negatively contributed to the changes in EIBF prevalence with -0.6pct and -14.2pct, respectively. However, the compositional differences in those living in Kalimantan & Sulawesi, first-time mothers, and small-born infants positively contributed to the change. Behaviour changes in mothers with higher education (8.8pct), from higher income households (-17.5pct), and those residing in Sumatra (-8.2pct) and Kalimantan & Sulawesi (-10.2pct) significantly contributed to the upward trend in EIBF prevalence.

CONCLUSIONS

Almost half of the newborns experienced delayed breastfeeding initiation despite the improvement in the prevalence of EIBF. Therefore, further research and interventions on behaviour change in mother's attitudes towards EIBF, especially among those undergoing caesarean delivery, living in Kalimantan or Sulawesi, and from wealthier households, are recommended to close this gap.

Determinants of egg consumption by infants and young children in Ethiopia

OBJECTIVE

To identify determinants of egg consumption in infants and young children aged 6-23·9 months in Ethiopia.

DESIGN AND SETTING

Data used were from the cross-sectional baseline survey of an egg campaign in Ethiopia implemented by the Global Alliance for Improved Nutrition.

PARTICIPANTS

Children aged 6-23·9 months (n 453) were sampled. Data on socio-demographic characteristics, economic resources, caregiver's behaviour, child health and feeding practices, and egg consumption in the last 7 d were collected using interviewer-administered questionnaires. Multivariable ordinal logistic regression was used to examine the association between explanatory variables and egg consumption in the last 7 d.

RESULTS

About half of children (53·4 %) did not consume eggs in the last 7 d. The odds of children consuming eggs were 4·33 (P < 0·002) times higher when their caregivers had some college education compared with no education. Wealth was positively (OR, 1·13, P = 0·029) and household food insecurity was negatively (OR, 0·96, P = 0·117) associated with child egg consumption. Purchasing eggs (OR, 9·73, P < 0·001) and caregiver's positive behavioural determinants (OR, 1·37, P = 0·005) were associated with child egg consumption. The associations of socio-demographic characteristics and economic resources with egg consumption provide evidence of partial mediation through caregiver behaviour and child health.

CONCLUSIONS

About half of children aged 6-23·9 months consumed eggs. Availability of eggs in households, mainly through purchase, was strongly associated with egg consumption. Education of caregivers and household heads and economic resources were associated with egg consumption and may operate through caregiver behaviour.

The role of maternal ideations on breastfeeding practices in northwestern Nigeria: a cross-section study

Background

Early initiation of breastfeeding within the first hour of birth and exclusive breastfeeding (EBF) for the first six months of life are beneficial for child survival and long-term health. Yet breastfeeding rates remain sub-optimal in Northwestern Nigeria, and such practices are often influenced by complex psychosocial factors at cognitive, social and emotional levels. To understand these influences, we developed a set of breastfeeding-related ideational factors and quantitatively examined their relationship with early initiation of breastfeeding and EBF practices.

Methods

A cross‐sectional population‐based survey was conducted in Kebbi, Sokoto, and Zamfara states from September–October 2019. A random sample of 3039 women with a child under-2 years was obtained. Respondents were asked about the two main outcomes, early initiation of breastfeeding and EBF, as well as breastfeeding-related ideations according to the Ideation Model of Strategic Communication and Behavior Change. Average marginal effects were estimated from mixed-effects logistic regression models adjusted for ideational and socio-demographic variables.

Results

Among 3039 women with a child under 2 years of age, 42.1% (95% CI 35.1%, 49.4%) practiced early initiation of breastfeeding, while 37.5% (95% CI 29.8%, 46.0%) out of 721 infants aged 0–5 months were exclusively breastfed. Women who knew early initiation of breastfeeding was protective of newborn health had 7.9 percentage points (pp) [95% CI 3.9, 11.9] higher likelihood of early initiation of breastfeeding practice than those who did not know. Women who believed colostrum was harmful had 8.4 pp lower likelihood of early initiation of breastfeeding (95% CI -12.4, -4.3) and EBF (95% CI -15.7%, -1.0%) than those without that belief. We found higher likelihood of early initiation of breastfeeding (5.1 pp, 95% CI 0.8%, 9.4%) and EBF (13.3 pp, 95% CI 5.0%, 22.0%) among women who knew at least one benefit of breastfeeding compared to those who did not know. Knowing the timing for introducing complementary foods andself-efficacy to practice EBF were also significantly associated with EBF practices.

Conclusion

Ideational metrics provide significant insights for SBC programs aiming to change and improve health behaviors, including breastfeeding practices, Various cognitive, emotional and social domains played a significant role in women’s breastfeeding decisions. Maternal knowledge about the benefits of breastfeeding to the mother (cognitive), knowledge of the appropriate time to introduce complementary foods (cognitive), beliefs on colostrum (cognitive), self-efficacy to breastfeed (emotional) and perceived social norms (social) are among the most important ideations for SBC programs to target to increase early initiation of breastfeeding and EBF rates in northwestern Nigeria.

Functions of social networks in maternal food choice for children in Mexico

Food choice for children has important implications in establishing early-life dietary habits and preferences. Food choice for children has been studied as parent-child dyad dynamics, but little is known about the extended system of relationships in maternal food choice for children. The objective of this study was to understand the functions of mothers' social networks in the food choices that mothers make for their children ages 1 to 5 years old in rural Mexico. In-depth interviews were conducted with 46 participants in three rural communities. The interviews inquired about participants' child-feeding practices, personal and local beliefs about child feeding and the individuals with whom they had conversations about food and child feeding. All interviews were conducted in Spanish, audio-recorded, transcribed verbatim, verified for quality and analysed using the constant comparative method. Five interconnected networks emerged, consisting of household family, non-household family, community, children's initial school and health and nutritional programme personnel. Each network had functions in food choice that ranged from shared food decision-making in the household family network to imparting formal dietary guidance in the health and nutritional programme personnel network. Across the networks, professionals, participants' mothers and mothers-in-law, community senior women and other women with children emerged as prominent figures whom participants would turn to for child-feeding advice. These findings provide empirical evidence that social networks, as an organized system of interconnected relationships, have vital functions in establishing social norms for food choices made for children that can be leveraged to promote healthy food choices.

Implementation of the Code of Marketing of Breast-Milk Substitutes in Vietnam: Marketing Practices by the Industry and Perceptions of Caregivers and Health Workers

BACKGROUND

The promotion of breastmilk substitutes (BMS) is an important barrier to successful breastfeeding.

OBJECTIVE

To examine the enactment and implementation of the Code of Marketing of Breast-Milk Substitutes (the Code) in Vietnam with a focus on marketing practices by the baby food industry and perceptions of caregivers, health workers, and policy makers.

METHODS

From May to July 2020, we conducted a mixed-method, cross-sectional study including a survey of 268 pregnant women and 726 mothers of infants aged 0-11 months and in-depth interviews with a subset of interviewed women (n = 39), policy makers, media executives, and health workers (n = 31).

RESULTS

In the previous 30 days, two mothers (out of 726) participating in the quantitative survey reported that health workers had recommended BMS, at private hospitals in both cases. In-depth interviews with health workers showed that hospitals have internal procedures to prevent the promotion of BMS by health workers. However, companies employed representatives to promote products not covered under the Code (e.g., commercial milk formula for pregnant women) at antenatal care visits and by gaining contact information from women and using this information to promote BMS outside the hospital, often on social media. In the 30 days preceding the survey, one-fifth of pregnant women were exposed to promotions of commercial milk formula for pregnant women and 7.1% to promotions of BMS. Among mothers of infants, 7.3% and 10.7% of respondents with infants aged 0-5 and 6-11 months, respectively, were exposed to some form of BMS promotion in the past 30 days. Around the time of birth, parents commonly brought BMS to maternity facilities (52.5%) or purchased it nearby (35.4%).

CONCLUSIONS

Although Vietnam has a strong regulatory environment for the protection, promotion, and support of breastfeeding, there are implementation, monitoring, and enforcement gaps. Stronger enforcement of national policies to regulate the presence of BMS industry representatives in health facilities-both public and private-and the promotion of BMS products on digital platforms are needed.

Engaging fathers to improve complementary feeding is acceptable and feasible in the Lake Zone, Tanzania

In Tanzania, suboptimal complementary feeding practices contribute to high stunting rates. Fathers influence complementary feeding practices, and effective strategies are needed to engage them. The objectives of this research were to examine the acceptability and feasibility of (1) tailored complementary feeding recommendations and (2) engaging fathers in complementary feeding. We conducted trials of improved practices with 50 mothers and 40 fathers with children 6-18 months. At visit 1, mothers reported current feeding practices and fathers participated in focus group discussions. At visit 2, mothers and fathers received individual, tailored counselling and chose new practices to try. After 2 weeks, at visit 3, parents were interviewed individually about their experiences. Interview transcripts were analysed thematically. The most frequent feeding issues at visit 1 were the need to thicken porridge, increase dietary diversity, replace sugary snacks and drinks and feed responsively. After counselling, most mothers agreed to try practices to improve diets and fathers agreed to provide informational and instrumental support for complementary feeding, but few agreed to try feeding the child. At follow-up, mothers reported improved child feeding and confirmed fathers' reports of increased involvement. Most fathers purchased or provided funds for recommended foods; some helped with domestic tasks or fed children. Many participants reported improved spousal communication and cooperation. Families were able to practice recommendations to feed family foods, but high food costs and seasonal unavailability were challenges. It was feasible and acceptable to engage fathers in complementary feeding, but additional strategies are needed to address economic and environmental barriers.

Fathers and grandmothers experiences participating in nutrition peer dialogue groups in Vihiga County, Kenya

Grandmothers and fathers are key influencers of maternal and child nutrition and are increasingly included in interventions. Yet, there is limited research exploring their experiences participating in interventions. This study reports on findings from a qualitative process evaluation of a quasi-experimental study that we conducted with grandmother and father peer dialogue groups to support maternal, infant and young child feeding practices in western Kenya. The aim was to explore grandmother and father experiences participating in interventions and how participation influences care and feeding practices. Grandmother and father peer educators received training to facilitate discussions about maternal and child nutrition, HIV and infant feeding, family communication, and family members' roles. Father peer educators also received training on gender inequities and power dynamics. In the original quasi-experimental study, the intervention was associated with increased social support and improvements in some complementary feeding practices. The process evaluation explored participants' experiences and how participation influenced infant care and feeding practices. We used Atlas.ti to thematically analyse data from 18 focus group discussions. The focus group discussions revealed that grandmothers and fathers valued their groups, the topics discussed and what they learned. Grandmothers reported improved infant feeding and hygiene practices, and fathers reported increased involvement in child care and feeding and helping with household tasks. Both described improved relationships with daughters-in-law or wives. This study highlights the importance of engaging influential family members to support child nutrition and identifies factors to build cohesion among group members, by building on grandmothers' roles as advisors and expanding fathers' roles in nutrition through gender transformative activities.

Engaging family members in maternal, infant and young child nutrition activities in low- and middle-income countries: A systematic scoping review

The influence of fathers, grandmothers and other family members on maternal, infant and young child nutrition practices has been well documented for decades, yet many social and behavioural interventions continue to reach only mothers. While recent guidelines recommend involving fathers, grandmothers and other family members in maternal and child nutrition, we lack a comprehensive review of interventions that have engaged them. This scoping review aimed to address this gap by describing social and behavioural interventions to engage family members in maternal and child nutrition in low- and middle-income countries. We systematically searched PubMed, Scopus, Web of Science, Global Health and CINAHL for peer-reviewed studies meeting inclusion criteria. We screened 6,570 abstracts, evaluated 179 full-text articles, and included 87 articles from 63 studies. Studies reported a broad range of approaches to engage fathers, grandmothers and other family members to support maternal nutrition (n = 6); breastfeeding (n = 32); complementary feeding (n = 6) and multiple maternal and child nutrition practices (n = 19). Interventions were facility and community based; included individual and group-based interpersonal communication, community mobilization, mass media and mHealth; and reached mothers and family members together or separately. Most interventions were located within the health sector; rare exceptions included nutrition-sensitive agriculture, social protection, early child development and community development interventions. Few interventions addressed gender norms, decision-making, and family dynamics or described formative research or theories informing intervention design. These diverse studies can shed light on innovative programme approaches to increase family support for maternal and child nutrition.

Mothers' perceptions on and learning from infant and young child-feeding videos displayed in Mother and Child Health Centers in Kenya: a qualitative and quantitative approach

OBJECTIVE

The objective was to explore mothers’ perceptions on educational videos on infant and young child-feeding practices, and to assess whether viewing frequencies would influence maternal knowledge, attitudes and feeding practices (KAP).

DESIGN

A set of forty-seven videos were displayed in health centres for 6 months. At 3 months, we conducted focus group discussions (FGD) with mothers and, at 6 months, administered KAP-questionnaire-based interviews to mothers. Using a quasi-experimental design, we compared groups according to video viewing frequencies.

SETTING

The study was conducted in a slum in Nairobi and a rural area in Machakos, Kenya. We installed TV screens in waiting rooms of six Mother and Child Health Centers, where mothers could choose to watch them.

PARTICIPANTS

Forty-three mothers with children aged 0–48 months participated in six FGD and 547 mothers of children aged 0–23 months in KAP interviews.

RESULTS

The mothers from the FGD found the videos acceptable and beneficial. Videos enhanced mothers’ learning and empowered them to support others in learning. The KAP data showed that after adjustments, breast-feeding (P = 0·06), complementary feeding knowledge (P = 0·01), complementary feeding attitudes (P = 0·08) and hygiene knowledge and practices (P = 0·003) were better among mothers who had seen videos three to four times, or five or more times, compared with mothers who had seen the videos once or twice.

CONCLUSIONS

Videos were an accepted form of education and were beneficial when watched repeatedly. The videos could be a good addition to current infant and young child-feeding education efforts in Kenya.

Child feeding practices and concerns: Thematic content analysis of Thai virtual communities

Parents' child feeding practices are influenced not only by family but also by a broader circle of networks, including online groups. Peer-to-peer platforms such as Facebook groups facilitate a learning environment and may influence the transmission of user-generated content into practice. These digital data not only benefit participants but also offer new opportunities for researchers to study related phenomena. Therefore, this study employs thematic content analysis to investigate peer-exchanging discourse conveyed in Facebook peer-support groups in children's diets in Thailand. To identify the area of interest, we classified and quantified the initial posts and investigated the relationship between initial posts' contents and community engagement. Thematic analysis was used to qualitatively describe the peer-exchanging content that responded to the initial posts. Of the five approved Facebook groups, 200 initial posts with their 1964 comments were extracted anonymously. Results revealed that Facebook groups devoted to diets for children have become a platform for Thai parents to seek informational and emotional support. The top-ranked initial posts were related to requesting knowledge and skills about age-appropriate food and meal preparation. Parents have also expressed anxiety about feeding and tension related to food fussiness which created the need for emotional support. Age-appropriate feeding, homemade baby foods, concerns about food seasonings and food allergy awareness were observable within online groups. However, a shift from traditional child feeding practices to new ideas created cultural gaps which lead to arguments in some families. Understanding these views would help guide to address parental concerns better.

Exploring the Influence of Social Norms on Complementary Feeding: A Scoping Review of Observational, Intervention, and Effectiveness Studies

The influence of social norms on child feeding is recognized, but guidance is lacking on how to address norms and related perceptions that hinder or support positive nutrition practices. We reviewed recent peer-reviewed and grey literature to summarize social norms relevant to complementary feeding (CF), intervention approaches that address norms, and their impacts on social norms and CF outcomes. Many reports described various norms, customs, and perceptions related to appropriate foods for young children, parenting practices, gender, and family roles, but rarely explored how they motivated behavior. Community engagement and media interventions addressed norms through facilitated discussions, challenging negative norms, portraying positive norms, engaging emotions, and correcting misperceptions. Evaluations of norms-focused interventions reported improved CF practices, but few assessed impacts on social norms. Although multiple contextual factors influence CF practices, evidence suggests the feasibility and effectiveness of addressing social norms as one component of programs to improve CF practices.

Mapping the patchwork: Exploring the subnational heterogeneity of child marriage in India

Despite dramatic reductions in child marriage over the past decade, more than one in four girls in India still marry before reaching age 18. This practice is driven by a complex interplay of social and normative beliefs and values that are inadequately represented in national- or even state-level analyses of the drivers of child marriage. A geographic lens was employed to assess variations in child marriage prevalence across Indian districts, identify hot and cold spots, and quantify spatial dependence and heterogeneity in factors associated with district levels of child marriage. Data were derived from the 2015-16 National Family Health Survey and the 2011 India Census, and represent 636 districts in total. Analyses included global Moran's I, LISAs, spatial Durbin regression and geographically weighted regression. This study finds wide inter- and intra-state heterogeneity in levels of child marriage across India. District levels of child marriage were strongly influenced by geographic characteristics, and even more so by the geographic characteristics of neighboring districts. Districts with higher levels of female mobile phone access and newspaper use had lower levels of child marriage. These relationships, however, were all subject to substantial local spatial heterogeneity. The results indicate that characteristics of neighboring districts, as well as characteristics of a district itself, are important in explaining levels of child marriage, and that those relationships are not constant across India. Child marriage reduction programs that are targeted within specific administrative boundaries may thus be undermined by geographic delineations that do not necessarily reflect the independent and interdependent characteristics of the communities who live therein. The geographic, social and normative characteristics of local communities are key considerations in future child marriage programs and policies.

•

Child marriage prevalence is highly heterogeneous across Indian districts.

•

Districts near state border districts tend to have higher levels of child marriage.

•

Characteristics of districts and their neighbors influence child marriage.

•

Geography affects the relationship between social normative factors and child marriage.

•

Child marriage interventions may require joint action across states.

Building Implementation Science in Nutrition

The field of nutrition has been investing in the development of many nutrition-specific and -sensitive policies and programs aimed at improving population-level malnutrition in all its forms. When there is a need to learn about a new system, programmatic context, or target population to understand how to effectively deploy an intervention to help improve nutrition, it is important to be able to ask a broad range of questions, both in topic and in scope. Our aim is to provide a simple and conceptually clear definition and principles to elaborate the science of implementation for nutrition to distinguish it from other ways of knowing and learning and to serve as a guide to the articulation of implementation science questions and methods. Implementation science is a body of systematized knowledge about how to improve implementation that 1) is distinguished by its aims to learn about the process of implementation, 2) uses methods that derive from and fit with the aims, and 3) is built with tacit (as well as expert) knowledge and experiential learning. Implementation science aims to generate the learning needed to improve implementation through facilitating collaboration among stakeholders to articulate and pursue the aims; capturing and using tacit knowledge and experiential learning from stakeholders, systems, providers, and recipients; and applying a mix of methods suited to the aims. This elaboration of the science provides a simple way to help those who already do, or want to do, implementation science understand and communicate how this science is unique and the value that it adds to the current landscape of nutrition priorities, innovations, and the attendant complex learning needs that follow. Implementation science encompasses both discovery- and mission-oriented research, and centers implementation as the object of study for the purposes of broad-based learning.

Large-Scale Social and Behavior Change Communication Interventions Have Sustained Impacts on Infant and Young Child Feeding Knowledge and Practices: Results of a 2-Year Follow-Up Study in Bangladesh

Background

Sustained improvements in infant and young child feeding (IYCF) require continued implementation of effective interventions. From 2010-2014, Alive & Thrive (A&T) provided intensive interpersonal counseling (IPC), community mobilization (CM), and mass media (MM) in Bangladesh, demonstrating impact on IYCF practices. Since 2014, implementation has been continued and scaled up by national partners with support from other donors and with modifications such as added focus on maternal nutrition and reduced program intensity.

Objective

We assessed changes in intervention exposure and IYCF knowledge and practices in the intensive (IPC + CM + MM) compared with nonintensive areas (standard nutrition counseling + less intensive CM and MM) 2 y after termination of initial external donor support.

Methods

We used a cluster-randomized design with repeated cross-sectional surveys at baseline (2010, n = 2188), endline (2014, n = 2001), and follow-up (2016, n = 2400) in the same communities, among households with children 0-23.9 mo of age. Within-group differences over time and differences between groups in changes were tested.

Results

In intensive areas, exposure to IPC decreased slightly between endline and follow-up (88.9% to 77.2%); exposure to CM activities decreased significantly (29.3% to 3.6%); and MM exposure was mostly unchanged (28.1-69.1% across 7 TV spots). Exposure to interventions did not expand in nonintensive areas. Most IYCF indicators in intensive areas declined from endline to follow-up, but remained higher than at baseline. Large differential improvements of 12-17 percentage points in intensive, compared with nonintensive areas, between baseline and follow-up remained for early initiation of and exclusive breastfeeding, timely introduction of foods, and consumption of iron-rich foods. Differential impact in breastfeeding knowledge remained between baseline and follow-up; complementary feeding knowledge increased similarly in both groups.

Conclusions

Continued IPC exposure and sustained impacts on IYCF knowledge and practices in intensive areas indicated lasting benefits from A&T's interventions as they underwent major scale-up with reduced intensity. This trial was registered at clinicaltrials.gov as NCT02740842.
