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
Identifying priority countries for scaling up small-quantity lipid-based nutrient supplements
INTRODUCTION: Undernutrition is a cause of nearly half of all deaths among children under 5 years old. Small-quantity lipid-based nutrient supplements (SQ-LNS) have been shown to prevent child wasting, stunting, anaemia and mortality among children 6-23 months of age in low- and middle-income countries (LMICs). Scaling up effective preventive interventions is urgent given the current global food insecurity and nutrition crisis. METHOD: To priorit…
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
Effect of Early‐Life Lipid‐Based Nutrient Supplement and Home Environment on Autonomic Nervous System Regulation at 9–11 Years
Nutrition and the home environment contribute to the development of the autonomic nervous system (ANS). However, no study has examined the long-term effects of prenatal and postnatal small-quantity lipid-based nutrient supplements (SQ-LNS) and home environment on ANS regulation. We investigated the effect of early-life SQ-LNS and home environment on ANS regulation at 9-11 years. Participants were children born to women who participated in a rando…
Prevalence of morbidity symptoms among pregnant and postpartum women receiving different nutrient supplements in Ghana and Malawi
Little is known about the impact of small-quantity lipid-based nutrient supplements (SQ-LNSs) on maternal morbidity. This secondary outcome analysis aimed to compare morbidity symptoms among women in two trials evaluating the efficacy of SQ-LNSs. From enrolment (≤20-week gestation) to 6 months postpartum, Ghanaian (n = 1320) and Malawian (n = 1391) women were assigned to consume daily: 60 mg iron and 400 μg folic acid until childbirth and placebo…
The cost-effectiveness of small-quantity lipid-based nutrient supplements for prevention of child death and malnutrition and promotion of healthy development
Objective: Recent meta-analyses demonstrate that small-quantity lipid-based nutrient supplements (SQ-LNS) for young children significantly reduce child mortality, stunting, wasting, anaemia and adverse developmental outcomes. Cost considerations should inform policy decisions. We developed a modelling framework to estimate the cost and cost-effectiveness of SQ-LNS and applied the framework in the context of rural Uganda. Design: We adapted costs …
Effect of multiple micronutrient supplements v . iron and folic acid supplements on neonatal mortality
Neonatal mortality did not differ between MMS and IFA regardless of Fe dose in either supplement
Association between asymptomatic infections and linear growth in 18–24‐month‐old Malawian children
Inadequate diet and frequent symptomatic infections are considered major causes of growth stunting in low-income countries, but interventions targeting these risk factors have achieved limited success. Asymptomatic infections can restrict growth, but little is known about their role in global stunting prevalence. We investigated factors related to length-for-age Z-score (LAZ) at 24 months by constructing an interconnected network of various infec…
Provision of small‐quantity lipid‐based nutrient supplements does not improve intestinal health among rural Malawian children
Lipid-based nutrient supplements (LNS) have been found to improve child growth and reduce child mortality. However, the mechanistic pathways for these improvements warrant exploration. One potential pathway is linked to improvement in intestinal health. Our study aimed to test a hypothesis that small-quantity LNS (SQ-LNS) could reduce the levels of intestinal inflammation, repair and permeability of children. As intestinal health markers we measu…
Association between prenatal provision of lipid‐based nutrient supplements and caesarean delivery
In populations with a high prevalence of childhood and adolescent undernutrition, supplementation during pregnancy aiming at improving maternal nutritional status and preventing fetal growth restriction might theoretically lead to cephalopelvic disproportion and delivery complications. We investigated whether the prenatal provision of small-quantity lipid-based nutrient supplements (SQ-LNS) was associated with an increased risk of caesarean secti…
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.
Effects of prenatal nutritional supplements on gestational weight gain in low- and middle-income countries
Consumption of multiple micronutrients or small-quantity lipid-based nutrient supplements containing iodine at the recommended dose during pregnancy, compared with iron and folic acid, does not affect…
Objectives: Inadequate iodine intake during pregnancy increases the risk of neonatal morbidity and mortality. We aimed to evaluate whether prenatal supplements containing iodine affect urinary iodine concentrations (UIC) of pregnant women in Malawi. Design: A randomised controlled trial. Pregnant women ( n 1391) were assigned to consume 60 mg/d Fe and 400 μg/d folic acid (IFA) or 18 vitamins and minerals including 250 μg/d iodine (MMN) or 20 g/d …

The impact of maternal supplementation during pregnancy and the first 6 months postpartum on the growth status of the next child born after the intervention period
Pregnancy and breastfeeding make demands on maternal nutrient stores. The extent of depletion and the degree to which nutrient stores are replenished between pregnancies has implications for a mother's nutritional status at conception of the subsequent child and therefore that child's birth outcomes and growth. Using follow-up data collected several years after a randomized effectiveness trial conducted in rural Bangladesh and a randomized effica…
Maternal and child factors associated with child body fatness in a Ghanaian cohort
Objective: We aimed to identify factors (child diet, physical activity; maternal BMI) associated with body composition of Ghanaian pre-school children. Design: Longitudinal analysis of the International Lipid-Based Nutrient Supplements (iLiNS)-DYAD-Ghana randomized trial, which enrolled 1320 pregnant women at ≤20 weeks’ gestation and followed them and their infants until 6 and 18 months postpartum, respectively. At follow-up, child age 4–6 years,…
Lipid-based nutrient supplements and all-cause mortality in children 6–24 months of age
Newborn physical condition and breastfeeding behaviours
Prenatal nutritional supplements may improve birth outcomes. This study aims to examine the effect of prenatal lipid-based nutrient supplements (LNS), compared with iron and folic acid (IFA), on general newborn physical condition and feeding behaviours. We conducted a cluster-randomized effectiveness trial that enrolled 4,011 pregnant women at ≤20 gestational weeks. LNS and IFA were provided to women in 48 and 16 clusters, respectively, for daily…
The association of early linear growth and haemoglobin concentration with later cognitive, motor, and social–emotional development at preschool age in Ghana
It is important to identify the periods during childhood when exposure to environmental risk factors results in long‐term neurodevelopmental deficits. Stunting and anaemia may be sensitive indicators of exposure to such risks. In a prospective cohort enrolled before birth, we investigated the association of developmental scores at 4–6 years with (a) birth length and linear growth during three postnatal periods and (2) haemoglobin (Hb) concentrati…
Gestational weight gain and newborn anthropometric outcomes in rural Bangladesh
Low gestational weight gain (GWG) is a known predictor of fetal growth restriction in higher income countries, but there is little information on this association in lower income countries. Our objective is to describe the association between GWG and birth outcomes among pregnant women in rural Bangladesh. Pregnant women were identified in a community-based programme and enrolled into the study at an average of 13 weeks' gestation (n = 4,011). Ma…
Contextualising complementary feeding in a broader framework for stunting prevention
An estimated 165 million children are stunted due to the combined effects of poor nutrition, repeated infection and inadequate psychosocial stimulation. The complementary feeding period, generally corresponding to age 6-24 months, represents an important period of sensitivity to stunting with lifelong, possibly irrevocable consequences. Interventions to improve complementary feeding practices or the nutritional quality of complementary foods must…

Unintended effects of a targeted maternal and child nutrition intervention on household expenditures, labor income, and the nutritional status of non-targeted siblings in Ghana
It is common for health and nutrition interventions to target specific household members and for evaluations of their effects to focus exclusively on those members. However, if a targeted intervention changes a household's utility maximization problem or influences decision-making, households might respond to the intervention in unintended ways with the potential to affect the wellbeing of non-targeted members. Using panel data from a randomized …

Dietary change among migrant and nonmigrant Mexican‐American families in Northern California
Dietary data were obtained from 71 migrant and 69 nonmigrant low‐income first‐generation Mexican‐American families. Among preschool children, average consumption from all food groups except vegetables was adequate. Most adults stated that their diet had improved since moving to the U.S. Dietary change was characterized by increased consumption of both “basic” and “new” foods, especially among nonmigrants, with considerable retention of “tradition…
Anthropometry of migrant and nonmigrant Mexican‐American children and adults in Northern California
Anthropometric data were obtained from children and adults of 71 migrant and 69 nonmigrant low‐income first‐generation Mexican‐American families. Nonmigrant children (1–11 years) were very close to U.S. standards in weight‐for‐age, height‐for‐age, weight‐for‐height and triceps skinfold, while migrant children were shorter and fatter. Adolescents (12–19 years) in both groups were shorter than U.S. standards, probably due to an increasing effect of…

Infant feeding practices of migrant Mexican‐American families in Northern California
Information on infant feeding practices was obtained for 226 children of 90 migrant Mexican‐American mothers. Of children born during 1975–1981, 56 per cent were breastfed at birth, 38 per cent at 3 months, 21 per cent at 6 months, and 3 per cent at 12 months. Thirty percent of breastfed children were given a supplementary bottle from birth. A variety of nonmilk liquids and semisolids were also given by bottle. Breast‐feeding incidence increased …
Height and weight of Southeast Asian preschool children in Northern California
Anthropometric data were obtained from 526 Southeast Asian preschool children during 1980-84. Length of time in the United States averaged 21.8 months. Mean weights and heights were substantially below the National Center for Health Statistics (NCHS) 50th percentile. Although 39 per cent of children were below the 5th percentile of height for age, only 7 per cent were below the 5th percentile of weight for height. Rates of weight and height gain …

Neonatal feeding patterns and reports of insufficient milk among low‐income urban Mexican mothers
Neonatal feeding patterns of 73 low‐income Mexican women who delivered vaginally and without complications a healthy term infant in 2 public maternity hospitals were studied in Hermosillo, Sonora, Mexico. Women were interviewed at hospital discharge and in their homes 8 and 16 days post‐partum (PP). Even though 71% reported full breastfeeding as the ideal feeding mode, only 47% were planning to follow this method at hospital discharge, by 16 days…

Update on Technical issues concerning Complementary Feeding of Young Children in Developing Countries and Implications for Intervention Programs
This paper provides an update to the 1998 WHO/UNICEF report on complementary feeding. New research findings are generally consistent with the guidelines in that report, but the adoption of new energy and micronutrient requirements for infants and young children will result in lower recommendations regarding minimum meal frequency and energy density of complementary foods, and will alter the list of “problem nutrients.” Without fortification, the …
Infant weight‐for‐length is positively associated with subsequent linear growth across four different populations
Several studies have documented that length gain often lags behind weight gain during infancy and early childhood, suggesting that linear growth is partly regulated by initial body mass or fatness. To investigate this hypothesis, we analysed data from four longitudinal studies on growth of infants in the first 12 months: (1) U.S. breast-fed and formula-fed infants (n = 89); (2) breast-fed infants in Ghana (n = 190); (3) normal birthweight, breast…
