RESUMEN
BACKGROUND: Little is known about text messaging's impact on child retention in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). OBJECTIVE: This study aimed to evaluate the impact of WICBuzz, a WIC agency drip marketing texting campaign, on retention and participation compared to a comparison WIC agency and to assess WIC participants' perceptions of the campaign's added value. DESIGN: A quasi-experimental design, with pre- and post-implementation measurement, was used to compare innovation and comparison groups' outcomes. Outcome evaluation integrated quantitative analysis of WIC management information system data and survey data of WICBuzz recipients' perceptions. PARTICIPANTS/SETTING: Data obtained for baseline (2019 calendar year) and implementation periods (March 1, 2020-February 28, 2021), included WIC participation for children who were WIC active at the beginning of each period. WIC agency sample sizes were 6,780-7,452 children from 5,189-5,832 households (baseline) and 4,599-5004 children from 3,186-4,297 households (implementation). INTERVENTION: WICBuzz, a drip-marketing text message campaign with targeted nutrition education and WIC brand awareness messages was the intervention. The comparison agency received standard WIC care. MAIN OUTCOME MEASURES: Main outcome measures included: recertification (re-enrollment during the implementation period), timely recertification (within 60 days of prior certification's termination), retention (WIC active at the study period's end), household WIC participation (continuous benefit issuance), and WICBuzz recipients' WIC perceptions. STATISTICAL ANALYSES PERFORMED: Statistical analysis included propensity score weighting and difference-in-difference modeling. Thematic analysis using a deductive approach was used to analyze the process evaluation findings. RESULTS: WICBuzz's impact on outcomes included 6.7% (95% CI: 3.8%, 9.5%) higher recertification, 7.4% (95% CI: 4.5%, 10.3%) higher retention, and 10.9% (95% CI: 8.0%, 13.8%) higher participation compared to the comparison agency. Most WICBuzz recipients reported added value regarding WIC knowledge and perceptions. CONCLUSIONS: WIC text message campaigns can improve participation and retention and improve participant perceptions of WIC's value.
RESUMEN
Adolescents in low- and middle-income countries (LMICs) are a vulnerable population given increased nutritional needs as puberty approaches. School-based nutrition programs exist in some settings, but the comprehensive provision of nutrition services requires knowledge of the mechanisms to reach out-of-school adolescents. A comprehensive scoping review was performed using formal and informal search strategies to landscape all potential delivery platforms with nutrition services to reach adolescents. Peer-reviewed studies, institutional strategies, program evaluations, and programmatic reports in LMICs were reviewed, including gray literature. A total of 87 out of 270 identified publications and reports describing nutrition programs for adolescents were identified. Although nutrition programs targeted at adolescents were sparse, various innovative and inclusive delivery platforms were included, such as school feeding programs, school-based anemia control, and nutrition-friendly school initiatives; health facility-based, youth-friendly health and nutrition services; social safety nets targeted at adolescents; community-based approaches targeting youth development and peer education within youth centers and faith-based settings; and technology-based platforms, including digital health services and mass media communication sensitization and mobilization efforts. Existing delivery mechanisms and platforms in health and other sectors that target adolescents offer great potential to extend nutrition interventions to this vulnerable yet hard-to-reach population.
RESUMEN
BACKGROUND/OBJECTIVES: The economic recession caused by the coronavirus disease 2019 pandemic disproportionately affected poor and vulnerable populations globally. Better uunderstanding of vulnerability to shocks in food supply and demand in the Asia Pacific region is needed. SUBJECTS/METHODS: Using secondary data from rapid assessment surveys during the pandemic response (n = 10,420 in mid-2020; n = 6,004 in mid-2021) in India, Indonesia, Myanmar, and Vietnam, this study examined the risk factors for reported income reduction or job loss in mid-2021 and the temporal trend in food security status (household food availability, and market availability and affordability of essential items) from mid-2020 to mid-2021. RESULTS: The proportion of job loss/reduced household income was highest in India (60.4%) and lowest in Indonesia (39.0%). Urban residence (odds ratio [OR] range, 2.20-4.11; countries with significant results only), female respondents (OR range, 1.40-1.69), engagement in daily waged labor (OR range, 1.54-1.68), and running a small trade/business (OR range, 1.66-2.71) were significantly associated with income reduction or job loss in three out of 4 countries (all P < 0.05). Food stock availability increased significantly in 2021 compared to 2020 in all four countries (OR range, 1.91-4.45) (all P < 0.05). Availability of all essential items at markets increased in India (OR range, 1.45-3.99) but decreased for basic foods, hygiene items, and medicine in Vietnam (OR range, 0.81-0.86) in 2021 compared to 2020 (all P < 0.05). In 2021, the affordability of all essential items significantly improved in India (OR range, 1.18-3.49) while the affordability of rent, health care, and loans deteriorated in Indonesia (OR range, 0.23-0.71) when compared to 2020 (all P < 0.05). CONCLUSIONS: Long-term social protection programs need to be carefully designed and implemented to address food insecurity among vulnerable groups, considering each country's market conditions, consumer food purchasing behaviors, and financial support capacity.
RESUMEN
RNA-binding proteins (RBPs) control messenger RNA fate in neurons. Here, we report a mechanism that the stimuli-induced neuronal translation is mediated by phosphorylation of a YTHDF1-binding protein FMRP. Mechanistically, YTHDF1 can condense with ribosomal proteins to promote the translation of its mRNA targets. FMRP regulates this process by sequestering YTHDF1 away from the ribosome; upon neuronal stimulation, FMRP becomes phosphorylated and releases YTHDF1 for translation upregulation. We show that a new small molecule inhibitor of YTHDF1 can reverse fragile X syndrome (FXS) developmental defects associated with FMRP deficiency in an organoid model. Our study thus reveals that FMRP and its phosphorylation are important regulators of activity-dependent translation during neuronal development and stimulation and identifies YTHDF1 as a potential therapeutic target for FXS in which developmental defects caused by FMRP depletion could be reversed through YTHDF1 inhibition.

To investigate SARS-CoV-2 transmission from humans to animals in Seoul, South Korea, we submitted samples from companion animals owned by persons with confirmed COVID-19. Real-time PCR indicated higher SARS-CoV-2 viral infection rates for dogs and cats than previously reported from the United States and Europe. Host-specific adaptations could introduce mutant SARS-CoV-2 to humans.

BACKGROUND: Research on moderate acute malnutrition (MAM) is limited, despite its high prevalence. This study examined outcomes of bi-weekly locally available foods provided via a food voucher program (FVP) on nutritional recovery [mid-upper arm circumference (MUAC) ≥ 125 mm] from MAM (defined as MUAC between 115 and 124 mm) and identified the factors associated with recovery rate in Kaélé health district, Far North Region of Cameroon. METHODS: This was a prospective study with 474 MAM children aged 6-59 months. Food voucher distribution and MUAC screening were conducted at 6 bi-weekly visits or until the child was recovered. Time to recovery was evaluated with multivariate Cox proportional regression hazard models with associations quantified using adjusted hazard ratio (aHR). The trend for MUAC, including its determinants, was examined with multivariate linear mixed effect models. RESULTS: The recovery rate was 78.3% by 6 weeks after the first food basket; 3.4% remained MAM, and 5.9% were transferred for treatment for severe acute malnutrition (SAM defined as MUAC < 115 mm). Boys were 34% more likely to recover from MAM than girls [aHR = 1.34, 95%CI (1.09, 1.67)]. Children aged 24-53 months were 30% more likely to recover than those aged 6-11 months [aHR = 1.30, 95%CI (0.99, 1.70)]. A one unit increase in weight-for-height Z-score (WHZ) was associated with 1.89-fold greater likelihood of recovery [aHR = 1.89, 95%CI (1.66, 2.14)]. Male children had on average 1.82 mm greater increase in MUAC than female children (p < 0.001). One unit increase in WHZ was associated with 3.42 mm increase in MUAC (p = 0.025). Children aged 12-23 and 24-53 months had 1.03 mm and 2.44 mm, respectively, greater increase in MUAC over the program than children aged 6-11 months (all p < 0.01). CONCLUSION: The recovery rate of MAM children treated with the FVP met the Sphere standards for targeted supplementary feeding programs (> 75%). Child's WHZ, gender and age were significant factors associated with MUAC increase and recovery from MAM in the FVP. These findings indicate the FVP approach shows promise as an effective alternative treatment for MAM with consideration of associated factors and merits further evaluation.

Fragile X syndrome (FXS) is the most common form of monogenic intellectual disability and autism, caused by the absence of the functional fragile X messenger ribonucleoprotein 1 (FMRP). FXS features include increased and dysregulated protein synthesis, observed in both murine and human cells. Altered processing of the amyloid precursor protein (APP), consisting of an excess of soluble APPα (sAPPα), may contribute to this molecular phenotype in mice and human fibroblasts. Here we show an age-dependent dysregulation of APP processing in fibroblasts from FXS individuals, human neural precursor cells derived from induced pluripotent stem cells (iPSCs), and forebrain organoids. Moreover, FXS fibroblasts treated with a cell-permeable peptide that decreases the generation of sAPPα show restored levels of protein synthesis. Our findings suggest the possibility of using cell-based permeable peptides as a future therapeutic approach for FXS during a defined developmental window.

This study explores common factors associated with not meeting minimum dietary diversity (MDD) among 27,072 children aged 6-23 months in Eastern and Southern Africa using data from nine Demographic and Health Surveys from 2013 to 2016. MDD was defined as consumption of more than or equals to five of eight food groups including breast milk in the past 24 h. Equity gaps were calculated as the difference in MDD prevalence between the top and bottom wealth quintiles. Logistic regression was conducted to identify common factors for not meeting MDD at the household, maternal and child levels across two or more countries to inform regional policies to improve children's diets. Kenya had the highest MDD wealth equity gap (40.4 pts), and South Africa had the smallest (14.4 pts). Equity gaps for flesh foods or eggs (up to 39.8 pp) were larger than for grain or legumes (up to 20 pp). Common risk factors for not reaching MDD included younger child age (6-11 months) (n = 9 countries), no formal maternal occupation (n = 6), not receiving vitamin-A supplementation (n = 3), younger maternal age (n = 3), lower maternal education (n = 3), no media (n = 3) or newspaper (n = 3) exposure, lower household wealth quintile (n = 3), use of nonefficient cooking fuel (n = 2), longer time to get to the water source (n = 2), not listening to the radio (n = 2) and higher birth order (n = 2). Priorities for improving MDD in the region include introducing diverse foods at a young age from 6 months with early nutrition counselling, promoting higher maternal education, increasing food purchasing power and ensuring the support of younger mothers.

BACKGROUND: Mobility restrictions and economic downfall as a result of the COVID-19 pandemic may increase the risk of child maltreatment, including increased risk for violent discipline use by parents. OBJECTIVE: We examined the socio-economic and psychosocial determinants of violent discipline among parents against children in Asia Pacific countries. PARTICIPANTS & SETTINGS: This secondary data analysis included 7765 parents with children 6-18 years old in eight Asia Pacific countries. METHODS: 24 potential determinants were identified, including household demographic factors, parents' psychosocial status, and livelihood changes. The dependent variable was parental use of violent discipline (physical, severe physical, psycho-social aggression, and any violent discipline). Univariate and multivariable logistic regression analysis was conducted. RESULTS: A total of 41 % of households reported violent discipline. Parental demographic characteristics that were positively related to use of violent discipline were living in rural areas, not being a household head, female sex, age younger than 35 years, and large family size. Poor parental mental health status, loss of job or reduced income due to COVID-19, lack of food at household level, parent engagement in petty trade, and owning a business also predicted violent discipline. Mandatory curfew and receiving pandemic-related education materials were also positive predictors. CONCLUSION: Some socio-demographic factors, economic hardship due to COVID-19, and poor mental health status of parents are associated with the use of violent discipline against children in the Asia Pacific region. These results highlight several potential target areas for child protection interventions by governmental and non-profit organizations, including economic, social, and mental health interventions.

BACKGROUND: Public health and clinical recommendations are established from systematic reviews and retrospective meta-analyses combining effect sizes, traditionally, from aggregate data and more recently, using individual participant data (IPD) of published studies. However, trials often have outcomes and other meta-data that are not defined and collected in a standardized way, making meta-analysis problematic. IPD meta-analysis can only partially fix the limitations of traditional, retrospective, aggregate meta-analysis; prospective meta-analysis further reduces the problems. METHODS: We developed an initiative including seven clinical intervention studies of balanced energy-protein (BEP) supplementation during pregnancy and/or lactation that are being conducted (or recently concluded) in Burkina Faso, Ethiopia, India, Nepal, and Pakistan to test the effect of BEP on infant and maternal outcomes. These studies were commissioned after an expert consultation that designed recommendations for a BEP product for use among pregnant and lactating women in low- and middle-income countries. The initiative goal is to harmonize variables across studies to facilitate IPD meta-analyses on closely aligned data, commonly called prospective meta-analysis. Our objective here is to describe the process of harmonizing variable definitions and prioritizing research questions. A two-day workshop of investigators, content experts, and advisors was held in February 2020 and harmonization activities continued thereafter. Efforts included a range of activities from examining protocols and data collection plans to discussing best practices within field constraints. Prior to harmonization, there were many similar outcomes and variables across studies, such as newborn anthropometry, gestational age, and stillbirth, however, definitions and protocols differed. As well, some measurements were being conducted in several but not all studies, such as food insecurity. Through the harmonization process, we came to consensus on important shared variables, particularly outcomes, added new measurements, and improved protocols across studies. DISCUSSION: We have fostered extensive communication between investigators from different studies, and importantly, created a large set of harmonized variable definitions within a prospective meta-analysis framework. We expect this initiative will improve reporting within each study in addition to providing opportunities for a series of IPD meta-analyses.

Given the high prevalence of child undernutrition in Bangladesh, multi-sectoral approaches involving livelihood promotion have potential to mitigate the burden of undernutrition. This study examined the impact of an economic development (ED) program providing poultry assets, gardening skills and saving training added to the Positive Deviant (PD)/Hearth program (PDH/ED), compared to PD/Hearth only (PDH). A total of 1029 children who attended PD/Hearth sessions in September-November 2018 at 6-13 months of age were enrolled in the cohort study in July-August 2019. The cohort, comprised of 532 children in the PDH/ED group and 593 children in the PDH group, was reassessed in November 2020. The program impact on child nutrition, food security, crop production, dietary quality and household income was estimated using a difference-in-differences approach accounting for the sociodemographic differences between PDH/ED and PDH groups. Compared to the PDH group, the PDH/ED group showed increases in child dietary diversity score (DDS) (+0.32), child minimum dietary diversity (13.7 percentage points [pp]), and maternal DDS (+0.28) (all p < 0.05). From 2019 to 2020, the PDH/ED households improved food security by 12.6 pp and diversified crop production (bananas (9.7 pp), papaya (11.1 pp), carrots (3.8 pp) and lemons (5.9 pp)), and increased the proportion of annual income ≥60,000 Taka by 12.4 pp and last month income ≥5000 Taka by 7.8 pp, compared to PDH group (all p < 0.05). However, there was no impact on child nutritional status, morbidity, livestock ownership and total annual/last income. Incorporating an ED program into nutrition programming could benefit food security and dietary diversity in rural Bangladesh.

There is growing recognition that engaging men in maternal, infant and young child nutrition (MIYCN) interventions can benefit child health and disrupt harmful gender norms. We conducted a cluster-randomized controlled trial in Tanzania, which engaged men and women in behaviour change via mobile messaging (short message service [SMS]) and traditional interpersonal communication (IPC), separately and in combination. Here, we evaluate intervention effects on individual-level men's MIYCN knowledge and discuss barriers to male engagement. Eligible clusters were dispensary catchment areas with >3000 residents. Forty clusters were stratified by population size and randomly allocated to the four study arms, with 10 clusters per arm. Data on knowledge and intervention exposure were collected from 1394 men through baseline and endline surveys (March-April 2018 and July-September 2019). A process evaluation conducted partway through the 15-18-month intervention period included focus group discussions and interviews. Data were analysed for key trends and themes using Stata and ATLAS.ti software. Male participants in the short message service + interpersonal communication (SMS + IPC) group reported higher exposure to IPC discussions than IPC-only men (43.8% and 21.9%, respectively). Knowledge scores increased significantly across all three intervention groups, with the greatest impact in the SMS + IPC group. Qualitative findings indicated that the main barriers to male participation were a lack of interest in health/nutrition and perceptions that these topics were a woman's responsibility. Other challenges included meeting logistics, prioritizing income-earning activities and insufficient efforts to engage men. The use of a combined approach fusing IPC with SMS is promising, yet countering gender norms and encouraging stronger male engagement may require additional strategies.

GGC repeat expansions within NOTCH2NLC have been identified as the genetic cause of neuronal intranuclear inclusion disease (NIID). To understand the molecular pathogenesis of NIID, here, we established both a transgenic mouse model and a human neural progenitor cells (hNPCs) model. Expression of the NOTCH2NLC with expanded GGC repeats produced widespread intranuclear and perinuclear polyglycine (polyG), polyalanine (polyA), and polyarginine (polyR) inclusions, leading to behavioral deficits and severe neurodegeneration, which faithfully mimicked the clinical and pathological features associated with NIID. Furthermore, conserved alternative splicing events were identified between the NIID mouse and hNPC models, among which was the enrichment of the binding motifs of hnRNPM, an RNA binding protein known as alternative splicing regulator. Expanded NOTCH2NLC-polyG and NOTCH2NLC-polyA could interact with and sequester hnRNPM, while overexpression of hnRNPM could ameliorate the cellular toxicity. These results together suggested that dysfunction of hnRNPM could play an important role in the molecular pathogenesis of NIID.

Background: Optimal child feeding practices contribute to reducing child undernutrition in low- and middle-income countries. Minimum dietary diversity (MDD) is a key indicator of complementary feeding quality for children aged 6-23 months. We aimed to examine the gender-common and gender-specific factors associated with the failure to meet MDD in eight Asia Pacific countries. Methods: The study used data of children aged 6-23 months from the Demographic and Health Surveys (DHS) conducted in Afghanistan (n = 8410), Bangladesh (n = 2371), Nepal (n = 1478), Pakistan (n = 3490), Cambodia (n = 2182), Indonesia (n = 5133), Myanmar (n = 1379), and Timor-Leste (n = 2115). A total of 41 household, maternal, and child-level variables were examined for association with MDD using univariate and multivariable logistic regressions. All analyses accounted for the survey design and sampling weights. Results: Being aged 6-11 months, not receiving Vitamin A supplementation, low maternal education, belonging to a low wealth quintile, and having two or more young children in the household were factors related to the failure to meet MDD among both male and female children. Mothers' not watching TV or not being exposed to media at least once a week, delivery at home, young age, and engagement to non-agricultural work were only significant risk factors among female children. Non-professional delivery assistance, unsafe disposal of children's stool, tolerant attitudes towards domestic violence, and rural residence were significant factors only among male children. Conclusions: It is possible that male and female children in the region may consume food in various ways, because the factors for meeting MDD are not the same for different genders of children. It is advised to enhance dietary diversity in child nutrition programmes through gender-specific activities.

INTRODUCTION: The WHO Nutrition Target aims to reduce the global prevalence of low birth weight by 30% by the year 2025. The Enhancing Nutrition and Antenatal Infection Treatment (ENAT) study will test the impact of packages of pregnancy interventions to enhance maternal nutrition and infection management on birth outcomes in rural Ethiopia. METHODS AND ANALYSIS: ENAT is a pragmatic, open-label, 2×2 factorial, randomised clinical effectiveness study implemented in 12 rural health centres in Amhara, Ethiopia. Eligible pregnant women presenting at antenatal care (ANC) visits at <24 weeks gestation are enrolled (n=2400). ANC quality is strengthened across all centres. Health centres are randomised to receive an enhanced nutrition package (ENP) or standard nutrition care, and within each health centre, individual women are randomised to receive an enhanced infection management package (EIMP) or standard infection care. At ENP centres, women receive a regular supply of adequately iodised salt and iron-folate (IFA), enhanced nutrition counselling and those with mid-upper arm circumference of <23 cm receive a micronutrient fortified balanced energy protein supplement (corn soya blend) until delivery. In standard nutrition centres, women receive routine counselling and IFA. EIMP women have additional screening/treatment for urinary and sexual/reproductive tract infections and intensive deworming. Non-EIMP women are managed syndromically per Ministry of Health Guidelines. Participants are followed until 1-month post partum, and a subset until 6 months. The primary study outcomes are newborn weight and length measured at <72 hours of age. Secondary outcomes include preterm birth, low birth weight and stillbirth rates; newborn head circumference; infant weight and length for age z-scores at birth; maternal anaemia; and weight gain during pregnancy. ETHICS AND DISSEMINATION: ENAT is approved by the Institutional Review Boards of Addis Continental Institute of Public Health (001-A1-2019) and Mass General Brigham (2018P002479). Results will be disseminated to local and international stakeholders. REGISTRATION NUMBER: ISRCTN15116516.

BACKGROUND/OBJECTIVES: This study examined socio-economic differences in diverse food consumption among children 6-23 months of age in South Asia and Southeast Asian countries. SUBJECTS/METHODS: Data from Demographic and Health Surveys in four countries in South Asia (n = 15,749) and four countries in Southeast Asia (n = 10,789) were used. Survey-design adjusted proportions were estimated for the following 10 food items: grains, legumes, dark green leafy vegetables (DGLV), vitamin A-rich fruits, vitamin A-rich vegetables, other fruits and vegetables (OFV), fish, meat, dairy, and eggs. An equity gap was defined as an arithmetic difference in the proportion of each food item consumed in the past 24-hours between the wealthiest and lowest quintiles and between rural and urban areas, denoted by percentage points (pp). RESULTS: The consumption of most of the 10 food items was higher in the wealthiest quintiles and urban areas across eight countries. The size of equity gaps was greater in Southeast Asia than in South Asia, particularly for vitamin A-rich fruits (3.3-30.0 pp vs. 0.3-19.6 pp), vitamin A-rich vegetables (12.1-26.7 pp vs. 2.4-5.9 pp), meat (17.7-33.4 pp vs. 3.4-13.4 pp), and dairy (14.7-32.5 pp vs. 3.3-11.4 pp). However, the size of equity gap in egg consumption was greater in Southeast Asia than South Asia (11.2-19.8 pp vs. 11.0-26.7 pp). Relatively narrower gaps were seen in the consumption of grains (0.3-12.9 pp), DGLV (0.6-12.4 pp), and fish (0.1-16.8 pp) across all countries. CONCLUSIONS: Equity gaps in food consumption differed by socio-economic status and region. Reducing equity gaps in nutrient-rich foods and utilizing regionally available food resources may increase child dietary quality.
RESUMEN
Fragile Xassociated tremor/ataxia syndrome (FXTAS) is a debilitating late-onset neurodegenerative disease in premutation carriers of the expanded CGG repeat in FMR1 that presents with a spectrum of neurological manifestations, such as gait ataxia, intention tremor, and parkinsonism [P. J. Hagerman, R. J. Hagerman, Ann. N. Y. Acad. Sci. 1338, 5870 (2015); S. Jacquemont et al., JAMA 291, 460469 (2004)]. Here, we performed whole-genome sequencing (WGS) on male premutation carriers (CGG55200) and prioritized candidate variants to screen for candidate genetic modifiers using a Drosophila model of FXTAS. We found 18 genes that genetically modulate CGG-associated neurotoxicity in Drosophila, such as Prosbeta5 (PSMB5), pAbp (PABPC1L), e(y)1 (TAF9), and CG14231 (OSGEPL1). Among them, knockdown of Prosbeta5 (PSMB5) suppressed CGG-associated neurodegeneration in the fly as well as in N2A cells. Interestingly, an expression quantitative trait locus variant in PSMB5, PSMB5rs11543947-A, was found to be associated with decreased expression of PSMB5 and delayed onset of FXTAS in human FMR1 premutation carriers. Finally, we demonstrate evidence that PSMB5 knockdown results in suppression of CGG neurotoxicity via both the RAN translation and RNA-mediated toxicity mechanisms, thereby presenting a therapeutic strategy for FXTAS.

Background: Reduced health and nutrition services as a result of coronavirus disease 2019 (COVID-19) measures endanger children's well-being. The Bangladesh Rajshahi Division of Maternal and Child Nutrition (BRDMCN; 2018-2020) involving social behavior change communication (SBCC) and an economic development (ED) of asset transfer was implemented. Objectives: This study describes how the implementation modality of the BRDMCN was adapted, and changes in the program's short/intermediate-term outcomes during the COVID-19 pandemic compared with pre-pandemic. Methods: The following evaluation components were assessed: 1) program fidelity, 2) program reach, 3) program acceptance, 4) perceived influence of COVID-19, and 5) short-term outcomes over the 3 y. We compared the first 2 y ("pre-COVID-19," from April 2018 through December 2019) and the final year ("during COVID-19," from January to December 2020) for all components except for (3) and (4). Data were collected through multiple sources: reviews of program annual progress reports, monitoring records of SBCC and ED programs, and cohort surveys (n = 1094). Results: The percentage dose delivery of activities decreased from 66.7-118% at pre-COVID-19 to 0-90% during COVID-19. The SBCC programs were altered to reduce the frequency of activities as well as the number of participants per session. The ED program involving large group meetings was modified to include within-member meetings, individual visits of community facilitators, or virtual discussions. Production activity using received assets continued during the pandemic, with no significant reduction compared with pre-COVID-19. The percentage of children recovering from underweight after 30 d of a Positive deviance/Hearth (PD/Hearth) session, a component of the SBCC program, remained constant at 16.5-20.3 percentage points before and during the COVID-19 pandemic. Conclusions: Program activities were scaled back and changed due to the pandemic. The BRDMCN maintained asset management and the degree of short-term outcomes over the course of a 3-y project. Further study is required to determine whether adaptive program management would achieve the long-term expected impact at a population level.
RESUMEN
BACKGROUND: Bangladesh has achieved notable economic progress in recent decades while economic inequality increased. Special attention is warranted on the ultra-poor population of the country. An 18 month-long economic development program, designed based on an ultra-poor graduation approach, was implemented to alleviate poverty and improve child nutrition in rural Bangladesh. OBJECTIVE: The study examined the impact of livelihood components of an economic development program on outcomes related to poultry/crop production, consumption, and income generation among the ultra-poor throughout quarterly follow-ups. METHODS: This secondary data analysis used the monitoring records of 2960 poor or ultra-poor households receiving assets of (1) 9-26 ducks (n = 2125), (2) 11 chickens (n = 872), and/or (3) vegetable seeds (n = 2407). Data measuring the production of assets, income generation, and consumption of assets were collected quarterly throughout 2019. To examine a one-year-long trend in participation, production, income generation, and consumption of assets, a one-way analysis of variance was conducted across the follow-ups. Additional analyses of annual income and consumption comparing duck and chicken groups were performed using linear regression models. RESULTS: The number of poultry assets per household decreased between the April- June and July-Sep follow-ups, while consumption of poultry and vegetable assets increased during the monsoon season (p < 0.001 for all). The vegetable production reflected seasonal fluctuations, where the lowest production and income were reported during the monsoon and pre-monsoon seasons. We observed increasing voluntary adoption of poultry farming among the non-asset group for both duck and chicken over the follow-ups (p < 0.001 for all). The households provided with duck assets gained a greater mean annual income compared to the households provided with chicken assets. CONCLUSIONS: Our findings highlight opportunities for strengthening the ultra-poor graduation approach on livelihood promotion in future scale-up in rural Bangladesh.
