Haemoglobin concentration thresholds that discriminate functional outcomes among children aged 6–30 months in eight countries
Introduction The WHO cut-offs to define anaemia among children (haemoglobin, Hb <105 g/L in 6–23 months and <110 g/L in 24–59 months) are based on the distribution of Hb concentrations in a healthy population. Our objective was to identify Hb values that best discriminate functional outcomes among children aged 6–30 months. Methods We used previously compiled datasets from an individual participant data meta-analysis of effects of small quantity …
Prevention of wasting and nutritional oedema
box Inclusion of prevention in the 2023 WHO guideline on wasting and nutritional oedema is a significant and timely addition, aligning with the global development goal of reducing current wasting prevalence from 6
Addressing prevention and management of wasting and nutritional oedema in children requires an improved evidence base on resource use and cost-effectiveness of interventions
box Effectiveness studies on the prevention and management of wasting and nutritional oedema should ideally include the evaluation of resource use and cost-effectiveness (CE) to allow future guideline development to appreciate this dimension
Educational impacts of an unconditional cash transfer program in Mali
In rural West Africa, the rate of out-of-school children is high and delayed entry to primary school is common, particularly for girls. Using the randomized roll-out of a large-scale unconditional cash transfer program in Mali, we examine its impact on child schooling by age and sex. The program leads to significant improvements in schooling outcomes for girls, but not boys. Improvements are especially salient among younger (ages 6–9) and older (…
Strengthening causal inference from randomised controlled trials of complex interventions
Researchers conducting randomised controlled trials (RCTs) of complex interventions face design and analytical challenges that are not fully addressed in existing guidelines. Further guidance is needed to help ensure that these trials of complex interventions are conducted to the highest scientific standards while maximising the evidence that can be extracted from each trial. The key challenge is how to manage the multiplicity of outcomes require…
Preventive small-quantity lipid-based nutrient supplements reduce severe wasting and severe stunting among young children
Including SQ-LNSs in preventive interventions to promote healthy child growth and development is likely to reduce rates of severe wasting and stunting. This meta-analysis was registered at www.crd.york.ac.uk/PROSPERO as CRD42019146592.

Poultry husbandry, water, sanitation, and hygiene practices, and child anthropometry in rural Burkina Faso
Poultry production in low income countries provides households with nutrient-rich meat and egg products, as well as cash income. However, traditional production systems present potential health and nutrition risks because poultry scavenging around household compounds may increase children's exposure to livestock-related pathogens. Data from a cross-sectional survey were analysed to examine associations between poultry, water, sanitation, and hygi…
Effects of multiannual, seasonal unconditional cash transfers on food security and dietary diversity in rural Burkina Faso
Objective To evaluate the impact of multiannual, seasonal unconditional cash transfers (UCT) provided within the Moderate Acute Malnutrition Out (MAM’Out) research project on households’ food security and children’s and caregivers’ dietary diversity. Design A two-arm cluster-randomized controlled trial with sixteen villages in the intervention group and sixteen others in the control group. A monthly allowance of 10 000 XOF was transferred to care…
Feasibility and impact study of a reward-based mobile application to improve adolescents’ snacking habits
Objective Adolescents’ snacking habits are driven by both explicit reflective and implicit hedonic processes. Hedonic pathways and differences in sensitivity to food rewards in addition to reflective determinants should be considered. The present study evaluated the feasibility and impact of a mobile phone-delivered intervention, incorporating explicit reflective and implicit rewarding strategies, on adolescents’ snack intake. Design Adolescents …

Dietary diversity predicts dietary quality regardless of season in 6–12-month-old infants in south-west Ethiopia
Objective Simple, cost-effective and convenient instruments like food group-based scores are proposed to assess micronutrient adequacy of children in developing countries. We assessed the predictive ability and seasonal stability of a dietary diversity score (DDS) to indicate dietary quality of infants. Design A 24 h dietary recall assessment was carried out on a sample of 320 and 312 breast-fed infants aged 6–12 months during harvest (HS) and pr…
Determinants of child malnutrition in rural and urban Ecuadorian highlands
Objective To identify and compare the sociodemographic determinants of stunting, wasting and overweight among infants of urban and rural areas in the Ecuadorian highlands. Design Cross-sectional study. Setting Nabon (rural) and Cuenca (urban) cantons, Azuay Province, Ecuador. Subjects A total of 703 children aged 0–24 months and their caregivers (227 rural and 476 urban) recruited during the period from June to September 2008. Results Stunting pr…
Mortality risk in preterm and small-for-gestational-age infants in low-income and middle-income countries
Risk of childhood undernutrition related to small-for-gestational age and preterm birth in low- and middle-income countries
BACKGROUND: Low- and middle-income countries continue to experience a large burden of stunting; 148 million children were estimated to be stunted, around 30-40% of all children in 2011. In many of these countries, foetal growth restriction (FGR) is common, as is subsequent growth faltering in the first 2 years. Although there is agreement that stunting involves both prenatal and postnatal growth failure, the extent to which FGR contributes to stu…
Predictors of validity and reliability of a physical activity record in adolescents
The physical activity record provided acceptable estimates for reliability and validity on a group level. Sex and setting were associated with validity estimates, whereas convenience to fill out the record was associated with better reliability estimates for LPA. This tendency of improved reliability estimates for adolescents reporting higher convenience merits further consideration
Predictors of chronic food insecurity among adolescents in Southwest Ethiopia
In the context of increased food prices, household income is an independent predictor of chronic food insecurity only among adolescents in the low income, urban households. Female gender, educational status of primary or less and being a member of households with high dependency ratio were independent predictors of chronic food insecurity in urban, semi-urban, and rural areas. The fact that the prevalence of chronic food insecurity increased amon…
Dietary behaviour, food and nutrient intake of pregnant women in a rural community in Burkina Faso
The aim of this study was to assess potential changes in dietary habits during pregnancy in a rural community in Houndé district, Burkina Faso. In-depth interviews were performed on a random sample of 37 pregnant women in order to analyse specific perceptions and attitudes regarding food consumption during pregnancy. In addition to this, an interactive 24-h recall survey was used to compare the food intake of 218 pregnant and 176 non-pregnant wom…
