          Abstract

          Abstract This article aims to review systematically the evidence on nutritional assessment techniques and parameters used to determine the nutritional status of children and adolescents. The literature review and the selection of publications were performed using the Medline, Lilacs, SciELO, Embase, personal files. 17 studies were identified, 7 addressed the anthropometric indices as the main outcome, 7 analyzed the growth and development of children and adolescents through growth curves, and the remainder surveyed body composition. In general, all met the quality criteria, unless 6 of the articles who did not discuss the limitations. The literature review suggests several techniques and parameters that can be applied to determine the nutritional status of children and adolescents from different countries. Growth graphs are essential to assess the health of children, but depend greatly of the growth tables used. Although BMI can be practical, it does not distinguish body fat from lean mass. The best interpretation of anthropometry will depend of valid reference values for age range of the study population. BIA is a quick feasible method, but the measurement has some various nationalities.

          Resumo O objetivo deste artigo é revisar sistematicamente as evidências sobre as técnicas de avaliação nutricional e parâmetros utilizados para determinar o estado nutricional em crianças e adolescentes. Revisão da literatura com busca nas bases de dados, Medline, Lilacs, SciELO e Embase, além de arquivos pessoais. Identificamos 17 artigos que relatavam dados de diferentes populações, sete estudos abordaram os índices antropométricos, quatro o crescimento e o desenvolvimento de crianças e adolescentes por meio de curvas de crescimento, e o restante a composição corporal. Todos preencheram os critérios de qualidade, com exceção das limitações. A revisão da literatura sugere diversas técnicas e parâmetros que podem ser aplicados para determinar o estado nutricional de crianças e adolescentes de diferentes países. Gráficos de crescimento são essenciais para avaliar a saúde de crianças, mas depende muito das tabelas de crescimento utilizadas. Embora o IMC seja prático, não distingue a gordura corporal de massa magra. Existem várias técnicas para avaliar proporções, tamanho e composição corporal. A melhor interpretação da antropometria dependerá de valores de referência válidos para a faixa etária da população estudada. BIA é um método factível, mas tem algumas limitações para a realização do exame.

          2000 CDC Growth Charts for the United States: methods and development.

          This report provides detailed information on how the 2000 Centers for Disease Control and Prevention (CDC) growth charts for the United States were developed, expanding upon the report that accompanied the initial release of the charts in 2000. The growth charts were developed with data from five national health examination surveys and limited supplemental data. Smoothed percentile curves were developed in two stages. In the first stage, selected empirical percentiles were smoothed with a variety of parametric and nonparametric procedures. In the second stage, parameters were created to obtain the final curves, additional percentiles and z-scores. The revised charts were evaluated using statistical and graphical measures. The 1977 National Center for Health Statistics (NCHS) growth charts were revised for infants (birth to 36 months) and older children (2 to 20 years). New body mass index-for-age (BMI-for-age) charts were created. Use of national data improved the transition from the infant charts to those for older children. The evaluation of the charts found no large or systematic differences between the smoothed percentiles and the empirical data. The 2000 CDC growth charts were developed with improved data and statistical procedures. Health care providers now have an instrument for growth screening that better represents the racial-ethnic diversity and combination of breast- and formula-feeding in the United States. It is recommended that these charts replace the 1977 NCHS charts when assessing the size and growth patterns of infants, children, and adolescents.

            Worldwide variation in human growth and the World Health Organization growth standards: a systematic review

            Objective The World Health Organization (WHO) has established a set of growth curves for use as international standards in children up to age 5. The WHO's position is that all economically advantaged children who were breastfed as infants grow similarly. As a result, a single set of growth charts can be used to judge growth in any child, regardless of race or ethnicity. The goal of this study was to compare mean heights, weights and head circumferences from a variety of studies with the WHO's data. Design We compared data from the WHO's Multicentre Growth Reference Study (MGRS) with data from studies performed in 55 countries or ethnic groups. Data sources PubMed, WHO Global Database on Child Growth and Malnutrition, SciELO, Google Scholar, Textbooks and Ministries of Statistics and Public Health. Eligibility criteria Large recent studies (1988–2013) of economically advantaged groups, including comparisons with cohorts of breastfed children wherever possible. Results Height varied somewhat among different national and ethnic groups. Means were generally within 0.5 of an SD of the MGRS means. Weight varied more than height, but the low MGRS means were seen as endorsing slenderness in the midst of an obesity epidemic. The mean head circumference varied widely. In many groups, means were consistently 0.5–1 SD above the MGRS mean. Head size in breastfed children at any age examined was far closer to local norms than to the MGRS means. Conclusions Height and weight curves may not be optimal fits in all cases. The differences between national or ethnic group head circumference means were large enough that using the WHO charts would put many children at risk for misdiagnosis of macrocephaly or microcephaly. Our findings indicate that the use of a single international standard for head circumference is not justified. Systematic Review Registration PROSPERO (# CRD42013003675).

              Supporting breastfeeding mothers: qualitative synthesis.

              This paper is a report of a synthesis of mothers' and healthcare professionals' experiences and perceptions of breastfeeding support. Despite increasing knowledge, breastfeeding rates remain relatively static and mothers continue to report dissatisfaction with their experiences of breastfeeding. Greater understanding of breastfeeding may be achieved through rigorous qualitative research, and there has been a recent increase in such studies. Electronic databases and citation lists of published papers were searched for articles listed between 1990 and 2005 and updated in May 2007. Studies were included if they used qualitative methods, were published in English, explored an aspect of breastfeeding and were based in a westernized country. Papers were included if they reported studies using qualitative methods to explore breastfeeding and were published in English and based in a westernized country. Each study was reviewed and assessed independently, key themes extracted and grouped, and secondary thematic analysis used to explore key concepts. From the 1990-2005 search, five themes emerged in health service support of breastfeeding: the mother-health professional relationship, skilled help, pressures of time, medicalization of breastfeeding and the ward as a public place. Social support had two themes: compatible and incompatible support. One additional theme emerged from the update to 2007: health professional relationships. Mothers tended to rate social support as more important than health service support. Health service support was described unfavourably with emphasis on time pressures, lack of availability of healthcare professionals or guidance, promotion of unhelpful practices and conflicting advice. Changes are required within the health services to address the needs of both mothers and staff.
