BACKGROUND The World Health Organization (WHO) released new Child Growth Standards in 2006 to replace the current National Center for Health Statistics (NCHS) growth reference. We assessed how switching from the NCHS to the newly released WHO Growth Standards affects the estimated prevalence of wasting, underweight and stunting, and the pattern of risk factors identified. METHODOLOGY/PRINCIPA...

Measurements of height and weight are important data source relating to growth and development, puberty, and nutritional status of children and adolescents. In clinical setting, the charts of the National Center for Health Statistics (NCHS), USA, are used in Iran. A survey identified significant differences in weight- and height-for-age across provinces, between urban and rural children. Althou...

A decade after ICD-10 s implementation, NCHS officials say they have seen both the good and the bad. ICD-10 has provided them with more specific data, which has been beneficial to NCHS s work in categorizing mortality statistics. But the transition to ICD-10 was a bumpy one for mortality coders and statisticians, according to Robe Anderson, PhD, chief of the mortality statistics branch of the D...

BACKGROUND Important differences exist in the diagnosis of malnutrition when comparing the 2006 World Health Organization (WHO) Child Growth Standards and the 1977 National Center for Health Statistics (NCHS) reference. However, their relationship with mortality has not been studied. Here, we assessed the accuracy of the WHO standards and the NCHS reference in predicting death in a population o...

We aimed to evaluate the classification of arm circumference (AC) in pre-school children by using National Center for Health Statistics (NCHS/CDC-2000) and World Health Organization (WHO-2006) references. We evaluated 205 children: weight, height and AC were assessed and the body mass index (BMI) was calculated. The BMI values were classified into Z-scores by the WHO referential. The AC was cla...

The National Center for Health Statistics (NCHS) conducts mortality follow-up for its major population-based surveys. In 2004, NCHS updated the mortality follow-up for the 1986-2000 National Health Interview Survey (NHIS) years, which because of confidentiality protections was made available only through the NCHS Research Data Center. In 2007, NCHS released a public-use version of the NHIS Link...

Cross-sectional data for breastfed infants in rural Zambia were used to evaluate the effect of applying two different data sets as a reference, i.e. the WHO 12-month breastfed pooled data set and the National Center for Health Statistics (NCHS) growth reference in terms of prevalence of malnutrition (stunting, underweight, and wasting). A total of 518 infants who were attending mother-and-child...

BACKGROUND In 2007, WHO published a new reference for assessing the nutritional status of children and adolescents aged 5 to 19 years, including body mass index (BMI) by sex and age. OBJECTIVE To compare the nutritional assessment by BMI in schoolchildren and adolescents using the actual Chilean Ministry of Health norm (NCHS) and the new WHO reference 2007. MATERIAL AND METHODS Retrospectiv...
