RESUMEN
Quality complementary feeding (CF) of infants and young children is key to their growth and development. But in Jordan, providing appropriate CF remains a challenge. This study assesses trends in infant and young child feeding (IYCF) practices, and consumption by infants and young children aged 6-23 months of breast milk substitutes (BMSs), sugar-sweetened beverages (SSBs), and micronutrient-rich foods in Jordan from 1990 to 2017. We combined dietary data on infants and young children from six Demographic and Health Surveys (DHS) (n = 14,880 children) to compute IYCF indicators. The latter included minimum dietary diversity (MDD), minimum meal frequency (MMF), and minimum acceptable diet (MAD), as well as intake of micronutrient-rich foods and food groups, specific SSBs, and infant formula. We conducted trend analyses using logistic regression models adjusted for child's age in month, child age squared, governorates, urban/rural residence, mother's educational attainment, and household wealth quintiles. We found that the proportion of consumption of micronutrient-rich food groups declined significantly between 1990 and 2017, with fewer infants and young children consuming eggs (OR = 0.39, p ≤ 0.001, 2002 reference), meat, poultry, and fish (OR = 0.25, p ≤ 0.001, 2002 reference), dairy (OR = 0.59, p ≤ 0.001, 2002 reference) and Vitamin A-rich fruits and vegetables (OR = 0.66, p ≤ 0.001, 2002 reference). Conversely, there was increased use of BMSs and sugar-sweetened juices that paralleled a decline in the share of infants and young children meeting appropriate CF practices and consuming micronutrient-rich foods and food groups. By 2017, children aged 6-23 months were significantly less likely to meet MDD, MMF, and subsequently MAD; the odds of consuming BMSs were almost three times the reference (OR = 3.8, p ≤ 0.001, 1990 reference), as were the odds of consuming sugar sweetened juices (OR = 3.63, p ≤ 0.001, 1990 reference). Food insecurity and undernutrition are low in Jordan; however, overweight and obesity rates are increasing concurrently as are micronutrient deficiencies. This highlights the need for policymakers to address factors at individual and household levels (behaviours and practices) as well as environmental issues (increasing access to unhealthy and ultraprocessed foods).

BACKGROUND: There is a need for empirical evidence on changes in employment and food consumption during pandemic situations in households belonging to the informal economy. OBJECTIVE: To examine changes in food insecurity, household diet diversity, and employment in agriculture during the pre-COVID-19 (2019-early 2020) and COVID-19 pandemic (September 2021) periods. METHODS: A total of 1632 households from a face-to-face pre-COVID-19 survey and 621 of those followed up by a telephonic survey during COVID-19 in Bihar, India, were included in the analyses. Household food insecurity, household diet diversity score (HDDS), and employment change (agriculture or nonagriculture) were assessed during both periods. Food insecurity and diet diversity in the 2 periods were examined by logistic regression. A change in the odds of being food insecure or having low HDDS was examined as an interaction between time and employment status. RESULTS: Prevalence of food insecurity increased from 21% to 55%, and low diet diversity increased from 47% to 69% in households assessed in both surveys. Employment status was not associated with food insecurity or low HDDS during the baseline survey. However, during the pandemic, â¼30% of households changed their employment from agriculture to nonagriculture and were more likely to be food insecure (adjusted odds ratio [aOR]: 2.77; 95% confidence interval [CI] 1. 78-4.32) and have low HDDS (aOR: 1.66; 95%CI: 1.05-2.61), than those who remained in agriculture. Similarly, those who retained nonagricultural employment during the pandemic were more likely to be food insecure (aOR: 2.23; 95%CI: 1.45-3.43) and have low HDDS (aOR: 1.73; 95%CI: 1.11-2.70), compared to those who remained in agriculture. In propensity score-adjusted interaction analysis of time and employment, food insecurity and low HDDS remained significantly associated with nonagricultural employment during the pandemic. CONCLUSIONS: Enhanced support to rural households in agricultural occupations could buffer them from unexpected crises, which may also protect their nutritional intake.
RESUMEN
Childhood wasting and stunting affect large numbers of children globally. Both are important risk factors for illness and death yet, despite the fact that these conditions can share common risk factors and are often seen in the same child, they are commonly portrayed as relatively distinct manifestations of undernutrition. In 2014, the Wasting and Stunting project was launched by the Emergency Nutrition Network. Its aim was to better understand the complex relationship and associations between wasting and stunting and examine whether current separations that were apparent in approaches to policy, financing, and programs were justified or useful. Based on the project's work, this article aims to bring a wasting and stunting lens to how research is designed and financed in order for the nutrition community to better understand, prevent, and treat child undernutrition. Discussion of lessons learnt focuses on the synergy and temporal relationships between children's weight loss and linear growth faltering, the proximal and distal factors that drive diverse forms of undernutrition, and identifying and targeting people most at risk. Supporting progress in all these areas requires research collaborations across interest groups that highlight the value of research that moves beyond a focus on single forms of undernutrition, and ensures that there is equal attention given to wasting as to other forms of malnutrition, wherever it is present.

BACKGROUND: The COVID-19 pandemic disrupted livelihoods and diets across the world. This study aimed to assess changes in household diet diversity and food consumption between the pre-COVID-19 period (December 2019-January 2020) and during the lockdown (March-May 2020), and to identify the socio-economic characteristics that determine these changes in rural Bihar, India. METHODS: Households that had provided their phone numbers in the pre-COVID-19 household survey (n = 1797) were contacted for interviews during the lockdown telephonic survey in a longitudinal survey in two districts (Gaya and Nalanda) in Bihar. In total, 939 households were interviewed. Using data on food consumption from both surveys, 876 households were included in the analysis. Food and Agriculture Organization's household diet diversity score (HDDS) was used to compare diet diversity between the pre-COVID-19 period and during the lockdown. Logistic regression was used to identify factors affecting household diet diversity and food consumption in the study households. RESULTS: Low diet diversity increased from 51.6% (95% CI 48.3-54.9) to 75.8% (95% CI 73.0-78.6) from the pre-COVID-19 to the lockdown period. Reduced food consumption was reported across all foods with nearly a quarter of the households reporting reduced consumption of fruits (27%), pulses (25%) and cereals (21%). Nearly 60% and above reported stopping consumption of nutrient-rich foods such as chicken, fish and eggs although the population was predominantly non-vegetarian. Logistic regression analysis revealed that taking a loan from neighbours/relatives (OR = 1.8; 95% CI 1.3-2.5) and belonging to lower social groups (OR = 1.8; 95% CI 1.1-2.9) increased odds of low HDDS. While those possessing ration cards had lower odds of reduced consumption of all food items, it was not associated with stopping consumption of any food item. In an unadjusted analysis, receipt of cash transfer during lockdown was also not associated with diet diversity (OR = 1.2; 95% CI 0.9-1.7). CONCLUSIONS: COVID-19 has impacted the consumption of nutrient-rich foods among already low-income rural households in India. Maintaining diet diversity among socio-economically vulnerable households during periods when food consumption is most threatened by shocks such as COVID-19 would need sustained government support in terms of social protection coverage and benefit transfers in rural communities.

Children with weight-for-age z-score (WAZ) <-3 have a high risk of death, yet this indicator is not widely used in nutrition treatment programming. This pooled secondary data analysis of children aged 6-59 months aimed to examine the prevalence, treatment outcomes, and growth trajectories of children with WAZ <-3 versus children with WAZ ≥-3 receiving outpatient treatment for wasting and/or nutritional oedema, to inform future protocols. Binary treatment outcomes between WAZ <-3 and WAZ ≥-3 admissions were compared using logistic regression. Recovery was defined as attaining mid-upper-arm circumference ≥12.5 cm and weight-for-height z-score ≥-2, without oedema, within a period of 17 weeks of admission. Data from 24,829 children from 9 countries drawn from 13 datasets were included. 55% of wasted children had WAZ <-3. Children admitted with WAZ <-3 compared to those with WAZ ≥-3 had lower recovery rates (28.3% vs. 48.7%), higher risk of death (1.8% vs. 0.7%), and higher risk of transfer to inpatient care (6.2% vs. 3.8%). Growth trajectories showed that children with WAZ <-3 had markedly lower anthropometry at the start and end of care, however, their patterns of anthropometric gains were very similar to those with WAZ ≥-3. If moderately wasted children with WAZ <-3 were treated in therapeutic programmes alongside severely wasted children, we estimate caseloads would increase by 32%. Our findings suggest that wasted children with WAZ <-3 are an especially vulnerable group and those with moderate wasting and WAZ <-3 likely require a higher intensity of nutritional support than is currently recommended. Longer or improved treatment may be necessary, and the timeline and definition of recovery likely need review.

Exposure to dietary aflatoxins has been recognized as a potential threat to child nutrition and growth, in addition to being a known carcinogen. The ability to accurately assess concentration of aflatoxin in the blood of at-risk individuals is therefore very important to inform public health policies and on-the-ground programs around the world. Venous blood is frequently used to quantify biomarkers of exposure such as AFB1-lysine adducts. However, venous blood collection methods are invasive, requiring highly trained staff, which makes this method challenging to implement, especially in resource-limited settings. In contrast, capillary blood collection by fingerprick is less invasive and has the potential for application in point-of-need monitoring. The aim of this exploratory study was to investigate the correlation and interchangeability of capillary and venous human blood samples in the quantification of AFB1-lysine adduct concentration. A total of 72 venous and capillary blood samples were collected from 36 women of reproductive age (16-49 years) in northern Uganda. All sample specimens were analyzed using high-performance liquid chromatography with fluorescence detection. Regression analysis and Bland-Altman analysis were performed to compare AFB1-lysine concentrations between venous and capillary sample pairs. Bland-Altman analysis of albumin-normalized AFB1-lysine data-bias was -0.023 pg/mg-albumin and the 95% limits of agreement were 0.51 to -0.56 pg/mg-albumin for log-transformed data. There was a positive correlation between albumin-normalized venous and capillary AFB1-lysine concentrations with r of 0.71 (p < .0001). A lack of any accepted clinical cutoff for aflatoxin exposure makes definition of an 'acceptable' limit for statistical analysis and comparison of methods challenging. Our data suggests a positive correlation between albumin-normalized AFB1-lysine concentrations in venous and capillary sample pairs, but relatively weak agreement and interchangeability based on Bland-Altman analysis.

INTRODUCTION: Women and infants are among the most vulnerable groups for micronutrient deficiencies. Pregnancy micronutrient status can affect birth outcomes and subsequent infants' growth. METHODS: We determined the relationship between maternal iron and vitamin A status at delivery using several biomarkers (ferritin, soluble transferrin receptor [sTFR], body iron stores [BIS], hemoglobin and retinol binding protein [RBP]) and birth outcomes (body weight, Z-scores, head circumference, small-for-gestational-age and preterm birth) in rural Uganda. We investigated women who had serum results at the point of delivery and paired them to their infants at birth (n = 1244). We employed multivariable linear and logistic regression, adjusting for clustering at the subcounty level to determine the relationship between maternal micronutrients and birth outcomes. RESULTS: After adjusting for relevant factors, we found that maternal iron status (ferritin and BIS) and anemia (hemoglobin) were not significantly associated with the assessed birth outcomes. However, there was a significant association between serum sTFR and preterm births (AOR: 0.67; 95% CI 0.48-0.94). For Vitamin A, we observed a significant positive association between RBP and length-for-age (LAZ) at birth (ß = 0.12, p < 0.030). DISCUSSION: These findings indicate that the relationship between maternal iron status and birth outcomes needs to be further investigated, because depending on the biomarker used the associations were either in favor of an adverse birth outcome or not significant. Additionally, they confirm that higher maternal RBP levels could be beneficial for birth outcomes. CLINICALTRIALS: gov as NCT04233944.

In 2014, the Emergency Nutrition Network published a report on the relationship between wasting and stunting. We aim to review evidence generated since that review to better understand the implications for improving child nutrition, health and survival. We conducted a systematic review following PRISMA guidelines, registered with PROSPERO. We identified search terms that describe wasting and stunting and the relationship between the two. We included studies related to children under five from low- and middle-income countries that assessed both ponderal growth/wasting and linear growth/stunting and the association between the two. We included 45 studies. The review found the peak incidence of both wasting and stunting is between birth and 3 months. There is a strong association between the two conditions whereby episodes of wasting contribute to stunting and, to a lesser extent, stunting leads to wasting. Children with multiple anthropometric deficits, including concurrent stunting and wasting, have the highest risk of near-term mortality when compared with children with any one deficit alone. Furthermore, evidence suggests that the use of mid-upper-arm circumference combined with weight-for-age Z score might effectively identify children at most risk of near-term mortality. Wasting and stunting, driven by common factors, frequently occur in the same child, either simultaneously or at different moments through their life course. Evidence of a process of accumulation of nutritional deficits and increased risk of mortality over a child's life demonstrates the pressing need for integrated policy, financing and programmatic approaches to the prevention and treatment of child malnutrition.

In rural Bangladesh, intake of nutrient-rich foods, such as animal source foods (ASFs), is generally suboptimal. Diets low in nutrients and lacking in diversity put women of reproductive age (WRA) at risk of malnutrition as well as adverse birth outcomes. The objective of this study was to assess the relationship between maternal dietary diversity, consumption of specific food groups and markers of nutritional status, including underweight [body mass index (BMI) < 18.5 kg/m2 ], overweight (BMI ≥ 23 kg/m2 ) and anaemia (haemoglobin < 120 g/dl) among WRA in Bangladesh. This analysis used data from the third round of a longitudinal observational study, collected from February through May of 2017. Dietary data were collected with a questionnaire, and Women's Dietary Diversity Score (WDDS) was calculated. Associations between WDDS, food group consumption and markers of nutritional status were assessed with separate adjusted logistic regression models. Among WRA, the prevalence of underweight, overweight and anaemia was 13.38%, 40.94% and 39.99%, respectively. Women who consumed dark green leafy vegetables (DGLV) or eggs were less likely to be anaemic or underweight, respectively, and women who consumed ASFs, particularly fish, were less likely to be underweight compared with women who did not consume these foods. WDDS did not show any consistent relationship with WRA outcomes. Interventions that focus on promoting optimal nutritional status among WRA in Bangladesh should emphasise increasing consumption of specific nutrient-rich foods, including ASFs, DGLV and eggs, rather than solely focusing on improving diet diversity in general.

Childhood stunting remains a public health burden worldwide. Although many studies have examined early life and in-utero risk factors; most have been observational and have used analytic techniques that make inferences limited to population means, thereby obscuring important within-group variations. This study addressed that important gap. Using data from a birth cohort of Ugandan infants (n = 4528), we applied group-based trajectory modelling to assess diverse patterns of growth among children from birth to 1-year old. A multinomial regression model was conducted to understand the relationship between risk factors and observed patterns across groups. We found that the onset of stunting occurred before birth and followed four distinct growth patterns: chronically stunted (Group 1), recovery (Group 2), borderline stunted (Group 3) and normal (Group 4). The average length-for-age z-score (LAZ) at birth was -2.6, -3.9, -0.6 and 0.5 for Groups 1-4, respectively. Although both Groups 1 and 2 were stunted at birth, stunting persisted in Group 1 while children in Group 2 recovered by the fourth month. Group 3 exhibited mild stunting while Group 4 was normal. Wasting and underweight were observed in all groups, with the highest prevalence of underweight in Group 1. Wasting gradually increased among children born already stunted (Groups 1 and 2). This showed the importance of distinguishing children by their growth patterns rather than aggregating them and only comparing population averages against global growth standards. The design of nutrition interventions should consider the differential factors and potential for growth gains relative to different risks within each group.

Evidence of the impact of exposure to multiple mycotoxins and environment enteric dysfunction (EED) on child growth is limited. Using data from a birth cohort study, the objectives of this study were to (a) quantify exposure to multiple mycotoxins (serum aflatoxin [AFB1 ] and ochratoxin A [OTA], urinary fumonisin [UFB1 ] and deoxynivalenol [DON]), as well EED (lactulose:mannitol [L:M] ratio); (b) examine the potential combined effects of multiple mycotoxin exposure and EED on growth. Multivariate regressions were used to identify associations between growth measurements (length, weight, anthropometric z-scores, stunting and underweight) at 24-26 months of age and exposure to mycotoxins and EED at 18-22 months (n = 699). Prevalence of AFB1 , DON, OTA and UFB1 exposure ranged from 85% to 100%; average L:M ratio was 0.29 ± 0.53. In individual mycotoxin models, AFB1 exposure was negatively associated with weight, WAZ, increased odds of stunting (odds ratio [OR]: 1.28, 95% confidence interval [CI]: 1.08, 1.52; p = 0.004) and underweight (OR: 1.18, 95% CI: 1.00, 1.38; p = 0.046). Irrespective of other mycotoxin exposure and presence of EED, AFB1 was negatively associated with length, weight, head circumference, LAZ and WAZ, and with increased odds of stunting and underweight, UFB1 was associated with increased odds of underweight, and DON was negatively associated with head circumference. EED was associated with the impaired length and weight. These findings suggest that certain mycotoxins and EED may have independent impacts on different facets of growth and that aflatoxin dominates such impacts. Thus, programs reducing exposure to mycotoxin and EED through multi-sectoral nutrition-sensitive interventions have the potential to improve child growth.

BACKGROUND: Where families eat together from a common dish, the shared meal must be nutrient dense enough in each nutrient to meet the needs of the highest-need member. OBJECTIVES: This study aimed to develop an aggregate household nutrient requirement benchmark that satisfies all members' needs in a context in which meals are shared and to illustrate how that metric could inform food and nutrition policy making. METHODS: We merged nationally representative survey data for Malawi in 2010, 2013, and 2016-2017 with individual nutrient requirements and local food composition data to compute the adequacy of each household's aggregate consumption given its demographic composition and primary occupation. To meet each person's nutrient needs at any level of energy balance, the nutrient density of their shared diet needs to be within boundaries of the most restrictive member. We classified the adequacy of each household's diet using these energy-adjusted densities and examined differences by sociodemographic characteristics. RESULTS: Accounting for meal sharing and nutrient density needs of the highest-need member, virtually all households' food consumption is insufficiently nutrient dense in riboflavin, selenium, lipids, and vitamin B-12, and most consumption is insufficiently nutrient dense in zinc and phosphorus as well. Meeting needs of women, adolescent girls, and young children using shared diets would on average require 145% more iron, 98% more zinc, and approximately 70% more phosphorus and vitamin C than if their needs were met with individualized diets. CONCLUSIONS: Establishing shared nutrient requirements is feasible using existing survey data and can help set sufficiency criteria in settings in which families share meals. In Malawi, current diets and food composition are inadequate for many nutrients, especially in households with more women and adolescent girls. The results call for concerted investment to increase access to and use of more nutrient-dense foods.

BACKGROUND: Measures that better describe "healthy" and sustainable recovery during nutritional treatment of children with moderate acute malnutrition (MAM) are needed. OBJECTIVES: We compared changes to body composition among children receiving 1 of 4 specialized nutritious food (SNFs) during treatment of MAM and by recovery and relapse outcomes. METHODS: The study was nested within a prospective, cluster-randomized, community-based, cost-effectiveness trial assessing 4 SNFs to treat children aged 6-59 mo with MAM [midupper arm circumference (MUAC) ≥11.5 cm and <12.5 cm without bipedal edema] in Sierra Leone. Biweekly SNF rations (1 of 3 fortified-blended foods or a lipid-based nutrient supplement) were given until children recovered (MUAC ≥12.5 cm), or up to 7 rations (â¼12 wk). Deuterium dilution was used to estimate fat-free mass (FFM) and fat mass (FM) at enrollment and after 4 wk of treatment to ensure similar treatment exposure among the participants. Another MUAC measurement was performed among recovered children 4 wk after program exit to determine whether recovery was sustained. ANOVA, paired t tests, and linear regression models were used to determine significant differences in changes from baseline to 4 wk. RESULTS: Among 312 analyzed participants, mean baseline weight comprised â¼80% FFM; mean weight gained after 4 wk comprised â¼82% FFM. Changes in FM and FFM among 4 SNFs were similar. Children who recovered gained more weight (241%), FFM (179%), and weight-for-height z score (0.44 compared with 0) compared with those who did not recover; sustainers gained 150% more weight. FM gains were positive among recovered children and sustainers, as well as negative among those who did not recover or sustain recovery, but not significantly different. CONCLUSIONS: Four SNFs had similar effects on body composition in children after 4 wk of treatment for MAM, showing a healthy pattern of weight gain, the majority being FFM. Differential responses to treatment underscore a need for further research to provide targets for healthy, sustainable recovery. This trial was registered at clinicaltrials.gov as NCT03146897.

BACKGROUND: Women's dietary diversity and quality are limited in low- and middle-income countries (LMICs). Nutrition-sensitive interventions that promote food crop diversity and women's access to income could improve diets and address the double burden of malnutrition in LMICs. OBJECTIVES: We examined the associations among food crop diversity and women's income-earning activities with women's diet quality, as well as effect modification by access to markets, in the context of small-holder food production in rural Tanzania. METHODS: Data from a cross-sectional study of 880 women from Rufiji, Tanzania, were analyzed. Women's dietary intake was assessed using a food frequency questionnaire. The prime diet quality score (PDQS; 21 food groups; range, 0-42), a unique diet-quality metric for women that captures the healthy and unhealthy aspects of diet, was computed. Generalized estimating equation linear models were used to evaluate the associations of food crop diversity and women's income-earning activities with PDQS, while controlling for socio-economic factors. RESULTS: Maternal overweight (24.3%) and obesity (13.1%) were high. The median PDQS was 19 (IQR, 17-21). Households produced 2.0 food crops (SD ± 1.0) yearly. Food crop diversity was positively associated with PDQS (P < 0.001), but the association was strengthened by proximity to markets (P for interaction = 0.02). For women living close (<1.1 km) to markets, producing 1 additional food crop was associated with a 0.67 (95% CI, 0.22-1.12) increase in PDQS, versus a 0.40 (95% CI, 0.24-0.57) increase for women living farther away. The PDQS increased with women's salaried employment (estimate, 0.96; 95% CI, 0.26-1.67). CONCLUSIONS: Household food production may interact with access to markets for sales and purchases, while nonfarm income also improves women's diet quality in rural Tanzania. Programs to improve women's diet quality should consider improving market access and women's access to income (source of empowerment), in addition to diversifying production.

BACKGROUND: The public health burden of undernutrition remains heavy and widespread, especially in low-income countries like Nepal. While predictors of undernutrition are well documented, few studies have examined the effects of political will and quality of policy or program implementation on child growth. METHODS: Data were collected from two nationwide studies in Nepal to determine the relationship between a metric of nutrition 'governance' (the Nutrition Governance Index), derived from interviews with 520 government and non-government officials responsible for policy implementation and anthropometry measured for 6815 children in 5556 households. We employed Generalized Estimating Equation (GEE) and multilevel regression models. RESULTS: A higher NGI (more effective nutrition governance) is positively associated with height-for-age as well as weight-for-height in children over 2 years of age compared to younger children (HAZ; ß = 0.02, p < 0.004, WHZ; ß = 0.01, p < 0.37). Results from the hierarchical model show that a one-point increase in the NGI is significantly associated with a 12% increase in HAZ and a 4% increase in WHZ in older children (> 24 months old). Mothers' education, child's age, BMI and no fever in the past 30 days were also protective of stunting and wasting. Seven percent and 17% of the overall variance in HAZ and WHZ, respectively, are accounted for by variations across the 21 district locations in which sampled households were located. Mean HAZ differs considerably across districts (intercept = 0.116, p < 0.001). CONCLUSIONS: These results highlight the importance of effective management of policy-based programming and resource use to bring about nutrition gains on the ground. The NGI explained a non-negligible amount of variation in HAZ and WHZ, which underscores the fundamental role that good governance plays in promoting child nutrition and growth, and the value of seeking to measure it to assist governments in moving policies from paper to practice.

Growth faltering in early childhood is prevalent in many low resource countries. Poor maternal dietary diversity during pregnancy has been linked with increased risk of fetal growth failure and adverse birth outcomes but may also influence subsequent infant growth. Our aim is to assess the role of prenatal maternal dietary diversity in infant growth in rural Uganda. Data from 3291 women and infant pairs enrolled in a birth cohort from 2014 to 2016 were analysed (NCT04233944). Maternal diets were assessed using dietary recall in the second or third trimesters of pregnancy. Maternal dietary diversity scores (DDS) were calculated using the FAO Minimum Dietary Diversity for Women (MDD-W). Cox regression models were used to evaluate associations of the DDS with the incidence of underweight, stunting and wasting in infants from 3 to 12 months, adjusting for confounding factors. The median DDS for women was low, at 3.0 (interquartile range 3.0-4.0), relative to the threshold of consuming five or more food groups daily. Infants of women in highest quartile of DDS (diverse diets) were less likely to be underweight (adjusted hazard ratio: 0.70, 95% confidence interval: 0.61, 0.80) compared with infants of women in Quartile 1 (p for trend <0.001) in models controlling for maternal factors. There was no significant association between DDS and stunting or wasting. Our findings suggest a relationship between higher maternal dietary diversity and lower risk of underweight in infancy. These findings suggest that programmes to improve infant growth could additionally consider strengthening prenatal dietary diversity to improve child outcomes globally.

BACKGROUND: Environmental enteric dysfunction (EED), characterized by altered intestinal permeability/inflammation, microbial translocation, and systemic inflammation (SI), may be a significant contributor to micronutrient deficiencies and poor growth in infants from low-resource settings. OBJECTIVE: We examined associations among EED, SI, growth, and iron status at 6 mo of age. METHODS: We performed a cross-sectional analysis of 6-mo-old infants (n = 548) enrolled in a Ugandan birth-cohort study (NCT04233944). EED was assessed via serum concentrations of anti-flagellin and anti- LPS immunoglobulins (Igs); SI was assessed via serum concentrations of É1-acid glycoprotein (AGP) and C-reactive protein (CRP); iron status was assessed via serum concentrations of hemoglobin (Hb), soluble transferrin receptor (sTfR), and ferritin. Associations were assessed using adjusted linear regression analysis. RESULTS: At 6 mo, â¼35% of infants were stunted [length-for-age z score (LAZ) < -2] and â¼53% were anemic [hemoglobin (Hb) <11.0 g/dL]. Nearly half (â¼46%) had elevated AGP (>1 g/L) and â¼30% had elevated CRP (>5 mg/L). EED and SI biomarkers were significantly correlated (r = 0.142-0.193, P < 0.001 for all). In adjusted linear regression models, which included adjustments for SI, higher anti-flagellin IgA, anti-LPS IgA, and anti-LPS IgG concentrations were each significantly associated with lower LAZ [ß (95% CI): -0.21 (-0.41, 0.00), -0.23 (-0.44, -0.03), and -0.33 (-0.58, -0.09)]. Furthermore, higher anti-flagellin IgA, anti-flagellin IgG, and anti-LPS IgA concentrations were significantly associated with lower Hb [ß (95% CI): -0.24 (-0.45, -0.02), -0.58 (-1.13, 0.00), and -0.26 (-0.51, 0.00)] and higher anti-flagellin IgG and anti-LPS IgG concentrations were significantly associated with higher sTfR [ß (95% CI): 2.31 (0.34, 4.28) and 3.13 (0.75, 5.51)]. CONCLUSIONS: EED is associated with both low LAZ and iron status in 6-mo-old infants. Further research on the mechanisms by which EED affects growth and micronutrient status is warranted.

OBJECTIVES: To examine the association between aflatoxin (AF) exposure during pregnancy and rate of gestational weight gain (GWG) in a sample of pregnant women of mixed HIV status in Gulu, northern Uganda. METHODS: 403 pregnant women were included (133 HIV-infected on antiretroviral therapy (ART), 270 HIV-uninfected). Women's weight, height and socio-demographic characteristics were collected at baseline (~19 weeks' gestation); weight was assessed at each follow-up visit. Serum was collected at baseline and tested for aflatoxin B1 -lysine adduct (AFB-lys) levels using high-performance liquid chromatography (HPLC). Linear mixed-effects models were used to examine the association between AFB-lys levels and rate of GWG. RESULTS: AFB-lys levels (detected in 98.3% of samples) were higher among HIV-infected pregnant women than HIV-uninfected pregnant women [median (interquartile range): 4.8 (2.0, 15.0) vs. 3.5 (1.6, 6.1) pg/mg of albumin, P < 0.0001]. Adjusting for HIV status, a one-log increase in aflatoxin levels was associated with a 16.2 g per week lower rate of GWG (P = 0.028). The association between AFB-lys and the rate of GWG was stronger and significant only among HIV-infected women on ART [-25.7 g per week per log (AFB-lys), P = 0.009 for HIV-infected women vs. -7.5 g per week per log (AFB-lys), P = 0.422 for HIV-uninfected women]. CONCLUSIONS: Pregnant women with higher levels of AF exposure had lower rates of GWG. The association was stronger for HIV-infected women on ART, suggesting increased risk.
OBJECTIFS: Examiner l'association entre l'exposition à l'aflatoxine (AF) pendant la grossesse et le taux de gain de poids pendant la grossesse (GWG) dans un échantillon de femmes enceintes de statut mixte VIH à Gulu, dans le nord de l' Ouganda. MÉTHODES: 403 femmes enceintes ont été incluses (133 infectées par le VIH sous traitement antirétroviral (ART), 270 non infectées par le VIH). Le poids, la taille et les caractéristiques sociodémographiques des femmes ont été collectés au départ (~19 semaines de gestation); le poids a été évalué à chaque visite de suivi. Le sérum a été recueilli au départ et testé pour les niveaux d'adduit d'aflatoxine B1 -lysine (AFB-lys) en utilisant la chromatographie liquide à haute performance (HPLC). Des modèles linéaires d'effets mixtes ont été utilisés pour examiner l'association entre les niveaux de AFB-lys et le taux de GWG. RÉSULTATS: Les niveaux de AFB-lys (détectés dans 98,3% des échantillons) étaient plus élevés chez les femmes enceintes infectées par le VIH que chez celles enceintes non infectées par le VIH [médiane (intervalle interquartile): 4,8 (2,0, 15,0) vs 3,5 (1,6, 6,1) pg/mg d'albumine, P <0,0001]. En ajustant pour le statut VIH, une augmentation d'un log des niveaux d'aflatoxine était associée à un taux de GWG inférieur de 16,2 g par semaine (P = 0,028). L'association entre AFB-lys et le taux de GWG était plus forte et significative seulement chez les femmes infectées par le VIH sous ART [-25,7 g par semaine et par log (AFB-lys), P = 0,009 pour les femmes infectées par le VIH contre -7,5 g par semaine et par log (AFB-lys), P = 0,422 pour les femmes non infectées par le VIH]. CONCLUSIONS: Les femmes enceintes présentant des niveaux plus élevés d'exposition à l'AF avaient des taux de GWG plus faibles. L'association était plus forte pour les femmes infectées par le VIH sous ART, ce qui suggère un risque accru.

BACKGROUND: Multiple specialized nutritious food options are programmed for supplementation in humanitarian and development settings. However, comparative cost-effectiveness evidence is lacking, let alone incorporation of perspectives from uncompensated stakeholders. A Burkina Faso trial evaluated the cost-effectiveness of Corn Soy Blend Plus w/ oil (CSB+ w/oil, reference arm), Corn Soy Whey Blend w/oil (CSWB w/oil), Super Cereal Plus (SC+), and Ready-to-Use Supplementary Food (RUSF) in reducing stunting and wasting among children 6-23 months old. This paper presents cost-effectiveness findings from multiple stakeholders' perspectives, including caregivers and program volunteers. METHODS: An activity-based costing with ingredients approach was used to summarize cost of the 18-month-long blanket supplementary feeding for each enrolled child (in 2018 USD). Time data were collected using self-reported and observational instruments. Cost-effectiveness relative to CSB+ w/oil assessed incremental cost per enrolled child against incremental outcomes: prevalence of stunting at 23 months of age and number of months of wasting. Two combined perspectives were compared: program (donor, implementer, and volunteer) versus program and caregiver (adding caregiver). RESULTS: A total of 6112 children were enrolled. While similar effectiveness was found in three arms (CSWB w/oil was less effective), costs differed. Product cost and caregiver time to prepare study foods were major drivers of cross-arm cost differences from the respective combined perspective. The two major drivers were used to construct uncertainty ranges of cost per enrolled child from program and caregiver perspective: $317 ($279- $355) in CSB+ w/oil, $350 ($327- $373) in CSWB w/oil, $387 ($371- $403) in RUSF, and $434 ($365- $503) in SC+. Cost from program and caregiver perspective was a substantial increase from program perspective. CSB+ w/oil was most cost-effective in reducing stunting and wasting, and this main finding was robust to changing perspectives and all corresponding sensitivity analyses when uncompensated time was valued at minimum wage ($0.36/h). The break-even point for uncompensated time valuation is >$0.84/h, where RUSF became the most cost-effective from the program and caregiver perspective. Relative cost-effectiveness rankings among the other three arms depended on choice of perspectives, and were sensitive to values assigned to product cost, international freight cost, opportunity cost of time, and outcomes of a hypothetical control. Volunteer opportunity cost did not affect arm comparisons, but lack of compensation resulted in negative financial consequences for caregivers. CONCLUSIONS: Evaluating cost-effectiveness by incorporating uncompensated stakeholders provided crucial implementation insights around nutrition products and programming.

OBJECTIVE: To compare the impact on child diet and growth of a multisectoral community intervention v. nutrition education and livestock management training alone. DESIGN: Longitudinal community-based randomized trial involving three groups of villages assigned to receive: (i) Full Package community development activities, delivered via women's groups; (ii) livestock training and nutrition education alone (Partial Package); or (iii) no intervention (Control). Household surveys, child growth monitoring, child and household diet quality measures (diet diversity (DD), animal-source food (ASF) consumption) were collected at five visits over 36 months. Mixed-effect linear regression and Poisson models used survey round, treatment group and group-by-round interaction to predict outcomes of interest, adjusted for household- and child-specific characteristics. SETTING: Banke, Nepal. PARTICIPANTS: Households (n 974) with children aged 1-60 months (n 1333). RESULTS: Children in Full Package households had better endline anthropometry (weight-for-age, weight-for-height, mid-upper-arm-circumference Z-scores), DD, and more consumption of ASF, after adjusting for household- and child-specific characteristics. By endline, compared with Partial Package or Control groups, Full Package households demonstrated preferential child feeding practices and had significantly more improvement in household wealth and hygiene habits. CONCLUSIONS: In this longitudinal study, a comprehensive multisectoral intervention was more successful in improving key growth indicators as well as diet quality in young children. Provision of training in livestock management and nutrition education alone had limited effect on these outcomes. Although more time-consuming and costly to administer, incorporating nutrition training with community social capital development was associated with better child growth and nutrition outcomes than isolated training programmes alone.
