Resumo
O estado nutricional da população infantil é um indicador relevante de saúde e qualidade de vida da população. Entretanto, faltam estudos longitudinais que dêem conta de avaliar a evolução do estado nutricional num mesmo grupo populacional, que confiram maior confiabilidade aos resultados. Assim, o objetivo desta pesquisa é, a partir de quatro estudos transversais e um longitudinal, avaliar a evolução do estado nutricional de escolares de 1a a 4a séries da rede pública do ensino fundamental da área urbana do município de Piracicaba/SP, de 2003 a 2006. Nesse período foram realizadas 16068 avaliações, sempre no segundo semestre de cada ano, em 9683 escolares de 12 unidades de ensino situadas nas 5 regiões administrativas da cidade de Piracicaba. Esses grupos de escolares avaliados anualmente foram chamados de levantamentos transversais. Ao grupo de escolares (n=347) acompanhado da 1a a 4a série, durante o mesmo período dos estudos transversais chamou-se grupo longitudinal. Foram aferidos o peso e a estatura e levantados dados de identificação pessoal (nome completo, sexo, data de nascimento, série e turma na escola). Os dados foram processados pelo programa Epi-info adotando-se a população de referência do NCHS/CDC - National Center Health Statistics/ Centers for Disease control and prevention - 2000 e expressos em escore-Z (Z) e percentil (P) dos indicadores de estatura para idade (E/I), peso para idade (P/I) e índice de massa corporal/idade (IMC/I). Para a classificação do estado nutricional foram adotados três critérios de pontos de corte segundo a curva da população de referência: NCHS/CDC, WHO – World Health Organization - e o adotado pelo Ministério da Saúde do Brasil. Para análise transversal, os escolares foram agrupados por idade, ano de avaliação e região. Já no estudo longitudinal foram agrupados por idade, que coincide com o ano...
The nutritional status of the pediatric population is a relevant indicator of the health and quality of life of the population. However, more longitudinal studies are needed to assess the nutritional status of a particular population group over time to improve the reliability of the results. Therefore, the objective of this study is to use four crosssectional studies and one longitudinal study to assess the nutritional status over time of first- to fourth-graders attending public elementary schools in the city of Piracicaba, SP, from 2003 to 2006. A total of 16068 assessments of 9683 schoolchildren of 12 schools located in the five administrative regions of Piracicaba were made during this period, always in the second semester of each year. These groups of schoolchildren assessed on a yearly basis were called cross-sectional groups. Another group of schoolchildren (n=347) was followed from first to fourth grades during the same period the cross-sectional studies were done. They were called longitudinal group. The following data were collected: name, gender, birth date, grade, class, weight and height. The data were processed by the software Epi-info using the NCHS/CDC - National Center for Health Statistics / Centers for Disease Control and Prevention - 2000 population as reference and expressed as z-scores (Z) and percentiles (P) of the indicators height-for-age (H/A), weight-for-age (W/A), and body mass index-forage (BMI/A). The nutritional status was classified according to the cutoff points given by the NCHS/CDC, World Health Organization (WHO) and that used by the Brazilian Ministry of Health. The schoolchildren were grouped by age, year of assessment and region for the cross-sectional assessment and grouped by age (which coincides with the year of assessment) for the longitudinal assessment. Changes in the nutritional status of these schoolchildren were characterized by reducing... (Complete abstract click electronic access below)
