[Field testing of new WHO growth standards: assessment of anthropometric outcomes of children from 0 to 5 years from Rosario city, Argentina].
BACKGROUND
The field testing of the preliminary WHO child growth standards was conducted in Rosario, Argentina. The objective of the article is to analyze the anthropometrical outcomes based on the national and international growth references. POPULATION, MATERIALS AND METHODS: Descriptive, cross-sectional study. Healthy children born at term, aged 0 to 5 years, and users of the health care network of the municipality from January to May 2005 were included. A data collection form was designed for the study. The weight (kg) was measured with an electronic scale. The length/height (cm) was taken with instruments constructed locally. The measurements techniques were based on national guidelines. The NUTRI 1.3: 5 and ANTHRO 2005 software were used.


RESULTS
A sample of 1.804 boys and girls was analyzed. The prevalence of underweight was 1,7 times higher in children less than 6 months with the application of the new standards compared to the national reference. For the rest of the age groups, the situation was the opposite. A major prevalence of stunting was observed after 6 months of age based on the new standards compared to the national reference. The prevalence of overweight, in comparison with the old growth international reference, increased with the use of the new standards.


CONCLUSIONS
Differences in underweight, stunting and overweight were found based on the tool used. The prevalence of stunting and overweight may increase with the application of the new growth standard.
