Predictors of anaemia in mothers and children in Uttar Pradesh, India.

OBJECTIVE: Anaemia affects more than half of Indian women and children, but the contribution of its causes remains unquantified. We examined interrelationships between Hb and nutritional, environmental, infectious and genetic determinants of anaemia in non-pregnant mothers and children in Uttar Pradesh (UP). DESIGN: We conducted a cross-sectional survey of households in twenty-five districts of UP between October and December 2016. We collected socio-demographic data, anthropometry and venous blood in 1238 non-pregnant mothers and their children. We analysed venous blood samples for malaria, Hb, ferritin, retinol, folate, Zn, vitamin B12, C-reactive protein, α1-acid glycoprotein (AGP) and ß-thalassaemia. We used path analysis to examine pathways through which predictors of anaemia were associated with Hb concentration. SETTING: Rural and urban households in twenty-five districts of UP. PARTICIPANTS: Mothers 18-49 years and children 6-59 months in UP. RESULTS: A total of 36·4 % of mothers and 56·0 % of children were anaemic, and 26·7 % of women and 44·6 % of children had Fe deficiency anaemia. Ferritin was the strongest predictor of Hb (ß (95 % CI) = 1·03 (0·80, 1·27) g/dL in women and 0·90 (0·68, 1·12) g/dL in children). In children only, red blood cell folate and AGP were negatively associated with Hb and retinol was positively associated with Hb. CONCLUSIONS: Over 70 % of mothers and children with anaemia had Fe deficiency, needing urgent attention. However, several simultaneous predictors of Hb exist, including nutrient deficiencies and inflammation. The potential of Fe interventions to address anaemia may be constrained unless coexisting determinants are jointly addressed.

Increasing Production Diversity and Diet Quality: Evidence from Bangladesh.

In the context of rural Bangladesh, we assess whether agriculture training alone, nutrition Behavior Communication Change (BCC) alone, combined agriculture training and nutrition BCC, or agriculture training and nutrition BCC combined with gender sensitization improve: (a) production diversity, either on household fields or through crop, livestock or aquaculture activities carried out near the family homestead and (b) diet diversity and the quality of household diets. All treatment arms were implemented by government employees. Implementation quality was high. No treatment increased production diversification of crops grown on fields. Treatment arms with agricultural training did increase the number of different crops grown in homestead gardens and the likelihood of any egg, dairy, or fish production but the magnitudes of these effect sizes were small. All agricultural treatment arms had, in percentage terms, large effects on measures of levels of homestead production. However, because baseline levels of production were low, the magnitude of these changes in absolute terms was modest. Nearly all treatment arms improved measures of food consumption and diet with the largest effects found when nutrition and agriculture training were combined. Relative to treatments combining agriculture and nutrition training, we find no significant impact of adding the gender sensitization on our measures of production diversity or diet quality. Interventions that combine agricultural training and nutrition BCC can improve both production diversity and diet quality, but they are not a panacea. They can, however, contribute towards better diets of rural households.

The glass of milk half-empty? Dairy development and nutrition in low and middle income countries.

Dairy products have an exceptionally rich nutrient profile and have long been promoted in high income countries to redress child malnutrition. But given all this potential, and the high burden of undernutrition in low- and middle-income countries (LMICs), why isn't dairy consumption more actively promoted in the developing world? In this review we focus on a broadly defined concept of "dairy development" to include production, trade, marketing, regulation, and demand stimulation. We address three key questions. First, how strong is the evidence on the importance of dairy production and consumption for improving nutrition among young children in LMICs? Second, which regions have the lowest consumption of dairy products? Third, what are the supply- and demand-side challenges that prevent LMICs from expanding dairy consumption? We argue that although more nutrition- and consumer-oriented dairy development interventions have tremendous potential to redress undernutrition in LMICs, the pathways for achieving this development are highly context-specific: LMICs with significant agroecological potential for dairy production primarily require institutional solutions for the complex marketing challenges in perishable milk value chains; lower potential LMICs require consumer-oriented trade and industrial approaches to the sector's development. And all dairy strategies require a stronger focus on cross-cutting issues of nutrition education and demand creation, food safety and quality, gender and inclusiveness, and environmental sustainability and resilience. We conclude our review by emphasizing important areas for research and policy expansion.

Behaviour change communication to improve complementary feeding practices in Ethiopia: Couples' beliefs concerning paternal involvement in childcare.

An important cause of stunting is limited consumption of complementary foods, in terms of both quantities and nutrients. Although existing studies show a positive association between fathers' engagement and children's diet, programmes designed to improve complementary feeding practices often only target mothers. In response to this, maternal behaviour change communication (BCC), paternal BCC and food voucher programmes were designed and implemented in Ethiopia using a clustered randomized controlled trial design. The paternal BCC programme included gender-equal messages to increase fathers' participation in childcare, household labour and decision making. The research reported in this paper is an examination of the BCC programmes, characterizing the behavioural, normative and control beliefs of both mothers and fathers in BCC households compared to those in control households. In this study, a total of 40 participants were included, with 13 mother-father pairs in the BCC + food voucher group, and seven pairs in the control group. Each participant was interviewed separately. We found that BCC mothers showed more gender-equal tendencies than the control mothers despite being more rural in location. By contrast, the beliefs of BCC and control fathers were similar overall, suggesting men are more resistant to gender-equal BCC. More work is needed to develop and test effective methods for changing fathers' beliefs and practices.

Engaging Fathers Through Nutrition Behavior Communication Change Does Not Increase Child Dietary Diversity in a Cluster Randomized Control Trial in Rural Ethiopia.

BACKGROUND: Adding food vouchers or paternal nutrition behavior change communication (BCC) activities to maternal BCC may improve child diets and household food security but their effect is unknown. OBJECTIVES: We assessed whether maternal BCC, maternal and paternal BCC, maternal BCC and a food voucher, or maternal and paternal BCC and a food voucher improved nutrition knowledge, child diet diversity scores (CDDS), and household food security. METHODS: We implemented a cluster randomized control trial in 92 Ethiopian villages. Treatments were as follows: maternal (M) BCC only; maternal BCC and paternal BCC (M+P); maternal BCC and food vouchers (M+V); and maternal BCC, food vouchers, and paternal BCC (M+V+P). Effects were assessed using generalized estimating equations. RESULTS: Maternal BCC and paternal BCC increased the maternal and paternal knowledge of optimal infant and young child feeding practices by 4.2-6.8 percentage points (P < 0.05) and by 8.3-8.4 percentage points (P < 0.01), respectively. Combining maternal BCC with either paternal BCC or the food voucher increased CDDS by 21.0%-23.1% (P < 0.05). The treatments M, M+V, and M+P increased the proportion of children who met minimum acceptable diet standards by 14.5, 12.8, and 20.1 percentage points, respectively (P < 0.01). Adding paternal BCC to the maternal BCC treatment or to the maternal BCC and voucher treatment did not lead to a larger increase in CDDS. CONCLUSIONS: Increased paternal involvement does not necessarily translate into improvements in child feeding outcomes. Understanding the intrahousehold decision-making dynamics that underlie this is an important area for future research. This study was registered at clinicaltrials.gov as NCT03229629.

Household dairy production, dairy intake, and anthropometric outcomes in rural Bangladesh.

We assess whether ownership of dairy cows is associated with a greater likelihood of consuming dairy products and with child anthropometric status in rural Bangladesh. Consistent with the assumption of imperfectly functioning markets for dairy products, ownership of dairy cows increases the likelihood that a child 6-59 months consumes milk by 7.7 percentage points with no difference in this association between boys and girls. This association nearly doubles in magnitude when we consider households that own a dairy cow that produced milk in the last year. This result is robust to the controls we use and the way in which we measure dairy cow ownership. Even when we saturate our model with child, maternal, household, wealth, as well as village fixed effects, we retain an association between dairy cow ownership and height-for-age z scores (HAZ) that is meaningful in magnitude - 0.13 standard deviations - and statistically significant at the one percent level. For children in the 12-23.9 month age group, ownership of a dairy cow is associated with a 0.37 SD increase in HAZ and a reduction of 11.3 percentage points in stunting. There is no statistically significant association with weight-for-height or wasting. These associations do not differ between boys and girls.

Comparing delivery channels to promote nutrition-sensitive agriculture: A cluster-randomized controlled trial in Bangladesh.

We use a randomized controlled trial in rural Bangladesh to compare two models of delivering nutrition content jointly to husbands and wives: deploying female nutrition workers versus mostly male agriculture extension workers. Both approaches increased nutrition knowledge of men and women, household and individual diet quality, and women's empowerment. Intervention effects on agriculture and nutrition knowledge, agricultural production diversity, dietary diversity, women's empowerment, and gender parity do not significantly differ between models where nutrition workers versus agriculture extension workers provide the training. The exception is in an attitudes score, where results indicate same-sex agents may affect scores differently than opposite-sex agents. Our results suggest opposite-sex agents may not necessarily be less effective in providing training. In South Asia, where agricultural extension systems and the pipeline to those systems are male-dominated, training men to deliver nutrition messages may offer a temporary solution to the shortage of female extension workers and offer opportunities to scale and promote nutrition-sensitive agriculture. However, in both models, we find evidence that the presence of mothers-in-law within households modifies the programs' effectiveness on some nutrition, empowerment, and attitude measures, suggesting that accounting for other influential household members is a potential area for future programming.

Respondent Fatigue Reduces Dietary Diversity Scores Reported from Mobile Phone Surveys in Ethiopia during the COVID-19 Pandemic.

BACKGROUND: The computer-assisted telephone interview (CATI) has been used extensively during the COVID-19 pandemic, but the effects of respondent fatigue during these interviews on responses to questions about diet are unknown. OBJECTIVES: We designed an experiment that randomized the placement of a survey module on the dietary diversity of rural Ethiopian women and assessed whether responses were altered by placing this module earlier or later in a phone survey. METHODS: Two CATIs were implemented; in the second, women were randomly assigned to answer questions on diet diversity either earlier or later in the interview. Women's Dietary Diversity Scores were the primary outcome. Secondary outcomes were dichotomous measures of consumption from four or more and five or more food groups and consumption of food groups consumed frequently, often, and rarely. Impacts were assessed using a respondent fixed effects model. RESULTS: Delaying the food consumption module by 15 min in the interview led to an 8%-17% (P < 0.01) decrease in reported Dietary Diversity Scores, a 28% (P < 0.01) decrease in the number of women who consumed a minimum of four dietary groups, and a 40% (P < 0.01) and 11% (P < 0.01) decrease in the reporting of consumption of animal source foods and fruits and vegetables, respectively. Moving the food consumption module closer to the beginning of the interview increased the number of reported food groups consumed by older women, women with a below-median education level, and women in larger households. CONCLUSIONS: Our findings suggest that comparisons of descriptive statistics across studies and countries on metrics such as food security and dietary quality may be confounded by where these modules are placed in the interview, thus highlighting trade-offs between volume of information collected and data quality when designing CATI surveys.

Qualitative exploration of the dynamics of women's dietary diversity. How much does economic empowerment matter?

OBJECTIVE: This study qualitatively examined dietary diversity among married women of reproductive age who engaged in two socio-economic activities to explore the dynamics of food availability, access, costs and consumption. DESIGN: Qualitative in-depth interviews. The food groups in the Minimum Dietary Diversity for women were used to explore women's dietary diversity. IDI were used to develop a roster of daily food consumption over a week. We explored food items that were considered expensive and frequency of consumption, food items that women require permission to consume and frequency of permission sought and the role of economic empowerment. Data analysis followed an inductive-deductive approach to thematic analysis. SETTING: Rural and peri-urban setting in Enugu State, Nigeria. PARTICIPANTS: Thirty-eight married women of reproductive age across two socio-economic groupings (women who work only at home and those who worked outside their homes) were recruited in April 2019. RESULTS: Economic empowerment improved women's autonomy in food purchase and consumption. However, limited income restricted women from full autonomy in consumption decisions and access. Consumption of non-staple food items, especially flesh proteins, would benefit from women's economic empowerment, whereas staple food items would not benefit so much. Dietary diversity is influenced by food production and purchase where factors including seasonal variation in food availability, prices, contextual factors that influence women's autonomy and income are important determinants. CONCLUSION: With limited income, agency and access to household financial resources coupled with norms that restrict women's income earning, women continue to be at risk for not achieving adequate dietary diversity.

Storytelling for persuasion: Insights from community health workers on how they engage family members to improve adoption of recommended maternal nutrition and breastfeeding behaviours in rural Bangladesh.

Community health workers (CHWs) increasingly provide interpersonal counselling to childbearing women and their families to improve adoption of recommended maternal and child nutrition behaviours. Little is known about CHWs' first-hand experiences garnering family support for improving maternal nutrition and breastfeeding practices in low-resource settings. Using focused ethnography, we drew insights from the strategies that CHWs used to persuade influential family members to support recommendations on maternal diet, rest and breastfeeding in a behaviour change communication trial in rural Bangladesh. We interviewed 35 CHWs providing at-home interpersonal counselling to pregnant women and their families in seven 'Alive & Thrive' intervention sites. In-depth probing focused on how CHWs addressed lack of family support. Thematic coding based on Fisher's narrative paradigm revealed strategic use of three rhetorical principles by CHWs: ethos (credibility), pathos (emotion) and logos (logic). CHWs reported selectively targeting pregnant women, husbands and mothers-in-law based on their influence on behavioural adoption. Key motivators to support recommended behaviours were improved foetal growth and child intelligence. Improved maternal health was the least motivating outcome, even among mothers. Logically coherent messaging resonated well with husbands, while empathetic counselling was additionally required for mothers. Mothers-in-law were most intransigent, but were persuaded via emotional appeals. Persuasion on maternal rest was most effort-intensive, resulting in contextually appealing but scientifically inaccurate messaging. Our study demonstrates that CHWs can offer important insights on context-relevant, feasible strategies to improve family support and uptake of nutrition recommendations. It also identifies the need for focused CHW training and monitoring to address scientifically flawed counselling narratives.

The effect of electronic job aid assisted one-to-one counselling to support exclusive breastfeeding among 0-5-month-old infants in rural Bangladesh.

Exclusive breastfeeding (EBF) for the first 6 months has established benefits, yet had slow improvements globally. Little is known about electronic job aid-assisted counselling to support EBF. As a secondary outcome of a cluster randomized controlled trial in Bangladesh, we assessed the effect of electronic job aid-supported nutrition counselling and practical demonstration on EBF. We randomized pregnant women to one of five study arms in the trial and followed mother-child dyads until 2 years of age. Community health workers (CHWs) provided breastfeeding counselling with or without prenatal and complementary nutrient supplements in all four intervention arms. The comparison arm continued with the usual practice where mothers could receive nutrition counselling at routine antenatal and postnatal care, and during careseeking for childhood illnesses. We assessed breastfeeding indicators at birth and monthly until the child was 6 months old, in both intervention and comparison arms. To evaluate the effect of nutrition counselling on breastfeeding, we combined all four intervention arms and compared them with the comparison arm. Intervention newborns had half the risk (relative risk [RR]: 0.54, 95% confidence interval [CI]: 0.39, 0.76) of receiving prelacteal feeds than those in the comparison arm. EBF declined steeply in the comparison arm after 3 months of age. EBF was 16% higher in the intervention than the comparison arm at 4 months (RR: 1.16, 95% CI: 1.08, 1.23) and 22% higher at 5 months of age (RR: 1.22, 95% CI: 1.12, 1.33). Maternal background and household characteristics did not modify the intervention effect, and we observed no difference in EBF among caesarean versus vaginal births. Breastfeeding counselling and practical demonstration using an electronic job aid by CHWs are promising interventions to improve EBF and are scalable into existing community-based programmes.

Effect of nutrition counselling with a digital job aid on child dietary diversity: Analysis of secondary outcomes from a cluster randomised controlled trial in rural Bangladesh.

Adequate dietary diversity among infants is often suboptimal in developing countries. We assessed the impact of nutrition counselling using a digital job aid on dietary diversity of children aged 6-23 months using data from a cluster randomised controlled trial in Bangladesh. The trial had five arms, each with 25 clusters. The four intervention arms provided counselling using a digital job aid and different prenatal and post-natal combinations of lipid-based supplements and the comparison arm with usual practice. We enrolled 1500 pregnant women and followed them until the children reached their second birthday. We developed a tablet-based system for intervention delivery, data collection and project supervision. We combined the four intervention arms (n = 855), in which community health workers (CHWs) provided age-appropriate complementary feeding counselling, to compare against the comparison arm (n = 403). We calculated the outcome indicators from the children's 24-h dietary recalls. Overall, the intervention increased the mean dietary diversity score by 0.09 (95% confidence interval [CI]: 0.2-0.16) and odds of minimum dietary diversity by 18% (95% CI: 0.99-1.40). However, there was a significant interaction on the effect of the intervention on dietary diversity by age. The mean dietary diversity score was 0.24 (95% CI: 0.11-0.37) higher in the intervention than in the comparison arm at 9 months and 0.14 (95% CI: 0.01-27) at 12 months of age. The intervention effect was non-significant at an older age. Overall, consumption of flesh food was 1.32 times higher in the intervention arm (odds ratio [OR] 1.32, 95% CI: 1.11-1.57) in 6-23 months of age. The intervention significantly improved child dietary diversity score in households with mild and moderate food insecurity by 0.27 (95% CI: 0.06-0.49) and 0.16 (0.05-27), respectively, but not with food-secure and severely food-insecure households. Although the study did not evaluate the impact of digital job aid alone, the findings indicate the utility of nutrition counselling by CHWs using a digital job aid to improve child feeding practices in broader programmes.

Early-Life Nutrition and Subsequent International Migration: A Prospective Study in Rural Guatemala.

BACKGROUND: It is generally accepted that migrants are favorably self-selected for labor market skills such as higher schooling and greater cognitive capacity, which are highly correlated with early-life nutrition. However, the influence of early-life nutrition on later-life migration is understudied. OBJECTIVE: The objective of this study was to examine prospectively the association between height-for-age z scores (HAZ) at 24 mo and subsequent international migration in a cohort of 2392 participants born between 1962 and 1977 in 4 rural villages in eastern Guatemala. METHODS: Information on nutritional status and covariates was collected between 1969 and 1977 and migration status was determined as of 2017 (at ages 40-57 y). We used proportional hazards and logistic regression models to assess whether HAZ was associated with international migration, adjusting for early-life and adult characteristics. RESULTS: Between 1978 and 2017 there were 297 international migrants (12.4% of the original cohort) during 99,212 person-y of follow-up. In pooled models that were adjusted for early-life characteristics, a 1-SD increase in HAZ was associated with a 19% increase in the risk of international migration (HR: 1.19; 95% CI: 1.02, 1.38). Further adjustment for village characteristics did not alter the estimate substantively (HR: 1.18; 95% CI: 1.02, 1.37), while additional adjustment for schooling attainment attenuated the estimate somewhat (HR: 1.14; 95% CI: 0.98, 1.33). In all models, effect sizes were stronger for men than for women. CONCLUSIONS: Our results indicate that early-life nutrition is positively associated with subsequent international migration.

A Nutrition-Sensitive Agroecology Intervention in Rural Tanzania Increases Children's Dietary Diversity and Household Food Security But Does Not Change Child Anthropometry: Results from a Cluster-Randomized Trial.

BACKGROUND: There are urgent calls for the transformation of agriculture and food systems to address human and planetary health issues. Nutrition-sensitive agriculture and agroecology promise interconnected solutions to these challenges, but evidence of their impact has been limited. OBJECTIVES: In a cluster-randomized trial (NCT02761876), we examined whether a nutrition-sensitive agroecology intervention in rural Tanzania could improve children's dietary diversity. Secondary outcomes were food insecurity and child anthropometry. We also posited that such an intervention would improve sustainable agricultural practices (e.g., agrobiodiversity, intercropping), women's empowerment (e.g., participation in decision making, time use), and women's well-being (e.g., dietary diversity, depression). METHODS: Food-insecure smallholder farmers with children aged <1 y from 20 villages in Singida, Tanzania, were invited to participate. Villages were paired and publicly randomized; control villages received the intervention after 2 y. One man and 1 woman "mentor farmer" were elected from each intervention village to lead their peers in agroecological learning on topics including legume intensification, nutrition, and women's empowerment. Impact was estimated using longitudinal difference-in-differences fixed-effects regression analyses. RESULTS: A total of 591 households (intervention: n = 296; control: n = 295) were enrolled; 90.0% were retained to study end. After 2 growing seasons, the intervention improved children's dietary diversity score by 0.57 food groups (out of 7; P < 0.01), and the percentage of children achieving minimum dietary diversity (≥4 food groups) increased by 9.9 percentage points during the postharvest season. The intervention significantly reduced household food insecurity but had no significant impact on child anthropometry. The intervention also improved a range of sustainable agriculture, women's empowerment, and women's well-being outcomes. CONCLUSIONS: The magnitude of the intervention's impacts was similar to or larger than that of other nutrition-sensitive interventions that provided more substantial inputs but were not agroecologically focused. These data suggest the untapped potential for nutrition-sensitive agroecological approaches to achieve human health while promoting sustainable agricultural practices.

Linear Growth Trajectories in Early Childhood and Adult Cognitive and Socioemotional Functioning in a Guatemalan Cohort.

BACKGROUND: Growth faltering in early childhood is associated with poor human capital attainment, but associations of linear growth in childhood with executive and socioemotional functioning in adulthood are understudied. OBJECTIVES: In a Guatemalan cohort, we identified distinct trajectories of linear growth in early childhood, assessed their predictors, and examined associations between growth trajectories and neurodevelopmental outcomes in adulthood. We also assessed the mediating role of schooling on the association of growth trajectories with adult cognitive outcomes. METHODS: In 2017-2019, we prospectively followed 1499 Guatemalan adults who participated in a food supplementation trial in early childhood (1969-1977). We derived height-for-age sex-specific growth trajectories from birth to 84 mo using latent class growth analysis. RESULTS: We identified 3 growth trajectories (low, intermediate, high) with parallel slopes and intercepts already differentiated at birth in both sexes. Children of taller mothers were more likely to belong to the high and intermediate trajectories [relative risk ratio (RRR): 1.21; 95% CI: 1.15, 1.26, and RRR: 1.11; 95% CI: 1.07, 1.15, per 1-cm increase in height, respectively] compared with the low trajectory. Children in the wealthiest compared with the poorest socioeconomic tertile were more likely to belong to the high trajectory compared with the low trajectory (RRR: 2.24; 95% CI: 1.29, 3.88). In males, membership in the high compared with low trajectory was positively associated with nonverbal fluid intelligence, working memory, inhibitory control, and cognitive flexibility at ages 40-57 y. Sex-adjusted results showed that membership in the high compared with low trajectory was positively associated with meaning and purpose scores at ages 40-57 y. Associations of intermediate compared with low growth trajectories with study outcomes were also positive but of lesser magnitude. Schooling partially mediated the associations between high and intermediate growth trajectories and measures of cognitive ability in adulthood. CONCLUSIONS: Modifiable and nonmodifiable risk factors predicted growth throughout childhood. Membership in the high and intermediate growth trajectories was positively associated with adult cognitive and socioemotional functioning.

Designing for empowerment impact in agricultural development projects: Experimental evidence from the Agriculture, Nutrition, and Gender Linkages (ANGeL) project in Bangladesh.

The importance of women's roles for nutrition-sensitive agricultural projects is increasingly recognized, yet little is known about whether such projects improve women's empowerment and gender equality. We study the Agriculture, Nutrition, and Gender Linkages (ANGeL) pilot project, which was implemented as a cluster-randomized controlled trial by the Government of Bangladesh. The project's treatment arms included agricultural training, nutrition behavior change communication (BCC), and gender sensitization trainings delivered to husbands and wives together - with these components combined additively, such that the impact of gender sensitization could be distinguished from that of agriculture and nutrition trainings. Empowerment was measured using the internationally-validated project-level Women's Empowerment in Agriculture Index (pro-WEAI), and attitudes regarding gender roles were elicited from both men and women, to explore potentially gender-transformative impacts. Our study finds that ANGeL increased both women's and men's empowerment, raised the prevalence of households achieving gender parity, and led to small improvements in the gender attitudes of both women and men. We find significant increases in women's empowerment scores and empowerment status from all treatment arms but with no significant differences across these. We find no evidence of unintended impacts on workloads and inconclusive evidence around impacts on intimate partner violence. Our results also suggest some potential benefits of bundling nutrition and gender components with an agricultural development intervention; however, many of these benefits seem to be driven by bundling nutrition with agriculture. While we cannot assess the extent to which including men and women within the same treatment arms contributed to our results, it is plausible that the positive impacts of all treatment arms on women's empowerment outcomes may have arisen from implementation modalities that provided information to both husbands and wives when they were together. The role of engaging men and women jointly in interventions is a promising area for future research.

Assessing statistical similarity in dietary intakes of women of reproductive age in Bangladesh.

Women of reproductive age (WRA) need adequate nutrient intakes to sustain a healthy pregnancy, support fetal growth, and breastfeed after childbirth. However, data on women's dietary intake in low- and middle-income countries (LMICs) are limited, and assessment of differences between dietary intakes of pregnant or lactating women compared with that of nonpregnant, nonlactating (NPNL) women is untested. Using single, multiple-pass 24-h dietary recall data from a sample of WRA residing in rural Bangladesh, we examined women's dietary intakes for energy, protein, calcium, iron, vitamin A, and dietary diversity for three groups: NPNL (n = 2,903), pregnant (n = 197), and lactating women (n = 944). We used equivalence testing to examine similarity in adjusted intakes for pregnant versus NPNL women and lactating versus NPNL women with a predetermined equivalence threshold based on recommendations specific for each reproductive stage. On average, both pregnant and lactating women had insufficient intakes for all dietary measures. Although statistically significant differences were observed between pregnant and NPNL women for energy intake and dietary diversity and between lactating and NPNL women for energy and protein intake, the magnitudes of these differences were too small to reject equivalence. Statistical similarity was also evident in all micronutrients and dietary diversity for both two-group comparisons. Understanding statistical differences and similarities between dietary measures of women in distinct reproductive stages has important implications for the relevance, appropriateness, and evaluation of maternal diet-enhancing interventions in LMICs, especially during pregnancy and lactation, when demand for macronutrients and micronutrients is elevated.

Shonjibon cash and counselling: a community-based cluster randomised controlled trial to measure the effectiveness of unconditional cash transfers and mobile behaviour change communications to reduce child undernutrition in rural Bangladesh.

BACKGROUND: Undernutrition is strongly associated with poverty - levels of undernutrition are higher in poor countries than in better-off countries. Social protection especially cash transfer is increasingly recognized as an important strategy to accelerate progress in improving maternal and child nutrition. A critical method to improve nutrition knowledge and influence feeding practices is through behaviour change communication intervention. The Shonjibon Cash and Counselling study aims to assess the effectiveness of unconditional cash transfers combined with a mobile application on nutrition counselling and direct counselling through mobile phone in reducing the prevalence of stunting in children at 18 months. METHOD: The study is a longitudinal cluster randomised controlled trial, with two parallel groups, and cluster assignment by groups of villages. The cohort of mother-child dyads will be followed-up over the intervention period of approximately 24 months, starting from recruitment to 18 months of the child's age. The study will take place in north-central Bangladesh. The primary trial outcome will be the percentage of stunted children at 18 m as measured in follow up assessments starting from birth. The secondary trial outcomes will include differences between treatment arms in (1) Mean birthweight, percentage with low birthweight and small for gestational age (2) Mean child length-for age, weight for age and weight-for-length Z scores (3) Prevalence of child wasting (4) Percentage of women exclusively breastfeeding and mean duration of exclusive breastfeeding (5) Percentage of children consuming > 4 food groups (6) Mean child intake of energy, protein, carbohydrate, fat and micronutrients (7) Percentage of women at risk of inadequate nutrient intakes in all three trimesters (8) Maternal weight gain (9) Household food security (10) Number of events for child suffering from diarrhoea, acute respiratory illness and fever (11) Average costs of mobile phone BCC and cash transfer, and benefit-cost ratio for primary and secondary outcomes. DISCUSSION: The proposed trial will provide high-level evidence of the efficacy and cost-effectiveness of mobile phone nutrition behavior change communication, combined with unconditional cash transfers in reducing child undernutrition in rural Bangladesh. TRIAL REGISTRATION: The study has been registered in the Australian New Zealand Clinical Trials Registry ( ACTRN12618001975280 ).

Randomized controlled trials of multi-sectoral programs: Lessons from development research.

Development is a multi-faceted process; achieving development goals thus requires a multi-sectoral approach. For over two decades, our research group of economists and nutritionists has designed and implemented randomized trials to assess the effectiveness of multisectoral programs in improving nutrition, food security, and other measures of well-being, largely at the request of developing country governments, development partners, and non-governmental organizations. Our approach addresses three perceived pitfalls of RCTs: the "black box" nature of RCTs, limited external validity, and challenges in translation of results to impacts at scale. We address these concerns by identifying and assessing programmatic pathways to impact with quantitative and qualitative methods; studying similar programs implemented by different organizations across various settings; and working closely with implementing partners in the design, research, and dissemination processes to inform adaptation and scale-up of programs and policies.

Rural Food Markets and Child Nutrition.

Child dietary diversity is poor in much of rural Africa and developing Asia, prompting significant efforts to leverage agriculture to improve diets. However, growing recognition that even very poor rural households rely on markets to satisfy their demand for nutrient-rich non-staple foods warrants a much better understanding of how rural markets vary in their diversity, competitiveness, frequency and food affordability, and how such characteristics are associated with diets. This article addresses these questions using data from rural Ethiopia. Deploying a novel market survey in conjunction with an information-rich household survey, we find that children in proximity to markets that sell more non-staple food groups have more diverse diets. However, the association is small in absolute terms; moving from three non-staple food groups in the market to six is associated with an increase in the number of non-staple food groups consumed by ˜0.27 and the likelihood of consumption of any non-staple food group by 10 percentage points. These associations are similar in magnitude to those de-scribing the relationship between dietary diversity and household production diversity; moreover, for some food groups, notably dairy, we find that household and community production of that food is especially important. These modest associations may reflect several specific features of our sample which is situated in very poor, food-insecure localities where even the relatively better off are poor in absolute terms and where, by international standards, relative prices for non-staple foods are very high.
