National, regional, and worldwide estimates of low birthweight in 2015, with trends from 2000
BACKGROUND: Low birthweight (LBW) of less than 2500 g is an important marker of maternal and fetal health, predicting mortality, stunting, and adult-onset chronic conditions. Global nutrition targets set at the World Health Assembly in 2012 include an ambitious 30% reduction in LBW prevalence between 2012 and 2025. Estimates to track progress towards this target are lacking; with this analysis, we aim to assist in setting a baseline against which…
Prevalence thresholds for wasting, overweight and stunting in children under 5 years
Objective Prevalence ranges to classify levels of wasting and stunting have been used since the 1990s for global monitoring of malnutrition. Recent developments prompted a re-examination of existing ranges and development of new ones for childhood overweight. The present paper reports from the WHO–UNICEF Technical Expert Advisory Group on Nutrition Monitoring. Design Thresholds were developed in relation to sd of the normative WHO Child Growth St…
Assessment of the WHO Stunting Framework using Ethiopia as a case study
Poor linear growth in children <5 years old, or stunting, is a serious public health problem particularly in Sub-Saharan Africa. In 2013, the World Health Organization (WHO) released a conceptual framework on the Context, Causes and Consequences of Childhood Stunting (the 'WHO framework') that identifies specific and general factors associated with stunting. The framework is based upon a global review of data, and we have applied it to a country-…
Nutritional disorders in the proposed 11th revision of the International Classification of Diseases
Objective To receive stakeholders’ feedback on the new structure of the Nutritional Disorders section of the International Classification of Diseases, 11th Revision (ICD-11). Design A twenty-five-item survey questionnaire on the ICD-11 Nutritional Disorders section was developed and sent out via email. The international online survey investigated participants’ current use of the ICD and their opinion of the new structure being proposed for ICD-11…
Childhood stunting
Childhood stunting is the best overall indicator of children's well-being and an accurate reflection of social inequalities. Stunting is the most prevalent form of child malnutrition with an estimated 161 million children worldwide in 2013 falling below −2 SD from the length-for-age/height-for-age World Health Organization Child Growth Standards median. Many more millions suffer from some degree of growth faltering as the entire length-for-age/he…
Complementary feeding and attained linear growth among 6–23-month-old children
Objective To examine the association between complementary feeding indicators and attained linear growth at 6–23 months. Design Secondary analysis of Phase V Demographic and Health Surveys data (2003–2008). Country-specific ANOVA models were used to estimate effects of three complementary feeding indicators (minimum meal frequency, minimum dietary diversity and minimum adequate diet) on length-for-age, adjusted for covariates and interactions of …
Maternal and child undernutrition and overweight in low-income and middle-income countries
The W orld H ealth O rganization's global target for reducing childhood stunting by 2025
In 2012, the World Health Organization adopted a resolution on maternal, infant and young child nutrition that included a global target to reduce by 40% the number of stunted under-five children by 2025. The target was based on analyses of time series data from 148 countries and national success stories in tackling undernutrition. The global target translates to a 3.9% reduction per year and implies decreasing the number of stunted children from …
Introducing infant and young child feeding indicators into national nutrition surveillance systems
A comprehensive set of infant and young child feeding (IYCF) indicators for international use was published in 2008. We describe the process followed to incorporate these indicators into Vietnam's National Nutrition Surveillance System (NNSS). Following its establishment in 1980, the National Institute of Nutrition introduced the Vietnam NNSS to provide an evidence base for nutrition interventions. While anthropometric indicators based on interna…
Parental height and child growth from birth to 2 years in the WHO M ulticentre G rowth R eference S tudy
Linear growth from birth to 2 years of children enrolled in the World Health Organization Multicentre Growth Reference Study was similar despite substantial parental height differences among the six study sites. Within-site variability in child length attributable to parental height was estimated by repeated measures analysis of variance using generalized linear models. This approach was also used to examine relationships among selected traits (e…
Association between WHO cut-offs for childhood overweight and obesity and cardiometabolic risk
Objective To examine the association between cardiovascular risk and childhood overweight and obesity using the BMI cut-offs recommended by the WHO. Design Children were classified as normal weight, overweight and obese according to the WHO BMI-for-age reference. Blood pressure, lipids, glucose, insulin, homeostasis model assessment–insulin resistance (HOMA-IR) and uric acid levels were compared across BMI groups. ANOVA and tests of linearity wer…
