Revista de Saúde Pública , 1998,
Abstract: OBJETIVO: Descrever os procedimentos metodológicos e algumas características demógrafo-sociais e da aten o médica da popula o estudada em um projeto de pesquisa em saúde perinatal realizado no Município de Ribeir o Preto, SP, Brasil, em 1994, visando a realizar compara es históricas com indicadores de saúde materno-infantil. MATERIAL E MéTODO: Entre junho de 1978 e maio de 1979 foram estudados todos os nascimentos hospitalares de Ribeir o Preto através de entrevistas com as m es, onde eram obtidos dados sobre hábitos maternos e paternos, situa o social da família, aten o médica à gesta o e parto, dura o da gesta o e dados antropométricos e de mortalidade dos recém-nascidos. Em 1994 foi realizado novo estudo com metodologia semelhante, sendo coletados dados de uma amostra de 1/3 dos nascimentos ocorridos no município naquele ano (todos os nascimentos hospitalares observados num período de 4 meses), e também a mortalidade desse grupo até um ano após o encerramento da coleta de dados do nascimento. As entrevistas eram realizadas após o parto, e o peso e comprimento da crian a eram aferidos logo após o nascimento. A mortalidade infantil foi avaliada através do levantamento de todos os óbitos de crian as nascidas durante o período do projeto até um ano após seu encerramento. RESULTADOS: Foram analisados 3.663 nascimentos, dos quais 3.579 eram nascimentos únicos; destes, 2.846 eram procedentes do município estudado. Quando comparados com os dados do estudo anterior, verifica-se que houve aumento da freqüência de alguns indicadores como m es adolescentes, prematuridade, baixo peso ao nascer e parto cesáreo; por outro lado, houve diminui o da metade da mortalidade infantil e seus componentes.

Abstract: objectives: to study the factors involved in the maintenance of exclusive breastfeeding in healthy infants during the first 4 months of life, with emphasis on the role of pediatricians. material and methods: a longitudinal study was carried out with 101 healthy term babies at a pediatrics outpatient clinic in uberaba, state of minas gerais, brazil. the babies were divided at random into three groups: g1, receiving advice from a multiprofessional breastfeeding team; g2, receiving advice from a pediatrician trained in breastfeeding; and g3, receiving advice from a pediatrician with no breastfeeding training. group randomization was confirmed by analysis of variance. the factors involved in the type of feeding at 4 months were analyzed by the chi-square test, by analysis of variance and by multiple variable analysis. results: at the end of follow-up, groups 1 and 2 showed similar percentages with respect to exclusive breastfeeding. in addition, the percentage of exclusively breastfed babies in groups 1 and 2 was significantly higher than in group 3 (p = 0.002). the use of a pacifier was negatively correlated with exclusive breastfeeding (p = 0.003). more maternal schooling increased the chance of exclusive breastfeeding at 4 months (p = 0.041). conclusion: in this study, a pediatrician who was prepared and motivated to encourage breastfeeding performed similarly to a multiprofessional breastfeeding team in terms of promoting exclusive breastfeeding until 4 months, a fact that was not observed when the pediatrician did not show this motivation. higher maternal schooling was associated with a higher frequency of exclusive maternal breast-feeding at 4 months, whereas the use of a pacifier favored early weaning.

Abstract: objective: to present concepts related to growth assessment, with emphasis on aspects concerning the evaluation of individuals. sources of data: the present paper is based on reports published by the who regarding the use anthropometry for the assessment of nutritional status; on original articles; and on book chapters about the same topic, as well as on the criticisms of auxologists of this type of assessment when employed at the individual level. summary of the findings: concepts concerning reference, skeletal maturity, mid-parental target height, z score, short stature, growth rate, body mass index, and their assumptions and limitations are presented. conclusions: the assessment of the nutritional status of a population is based on cut-off points, taking into consideration that whoever is below or above that point presents a nutritional problem. clinical evaluation is based on the idea of variability, which can be both biological and social, and on the idea that it is the clinician's task to establish whether a child within or outside given parameters presents normal growth and nutritional status. when monitoring the growth of a child or adolescent, the most important parameter to be considered is growth rate.

Abstract: objective: to identify risk factors for low birth weight (lbw) among live births by vaginal delivery and to determine if the disappearance of the association between lbw and socioeconomic factors was due to confounding by cesarean section. methods: data were obtained from two population-based cohorts of singleton live births in ribeir?o preto, southeastern brazil. the first one comprised 4,698 newborns from june 1978 to may 1979 and the second included 1,399 infants born from may to august 1994. the risks for lbw were tested in a logistic model, including the interaction of the year of survey and all independent variables under analysis. results: the incidence of lbw among vaginal deliveries increased from 7.8% in 1978?79 to 10% in 1994. the risk was higher for: female or preterm infants; newborns of non-cohabiting mothers; newborns whose mothers had fewer prenatal visits or few years of education; first-born infants; and those who had smoking mothers. the interaction of the year of survey with gestational age indicated that the risk of lbw among preterm infants fell from 17.75 to 8.71 in 15 years. the mean birth weight decreased more significantly among newborns from qualified families, who also had the highest increase in preterm birth and non-cohabitation. conclusions: lbw among vaginal deliveries increased mainly due to a rise in the proportion of preterm births and non-cohabiting mothers. the association between cesarean section and lbw tended to cover up socioeconomic differences in the likelihood of lbw. when vaginal deliveries were analyzed independently, these socioeconomic differences come up again.

Abstract: OBJETIVO: apresentar conceitos relacionados à avalia o do crescimento, ressaltando os aspectos da avalia o do indivíduo. FONTES DOS DADOS: o artigo foi desenvolvido tomando como base as publica es que discutem a aplica o da antropometria na avalia o do estado nutricional, publicadas pela OMS, artigos originais e capítulos de livros com esse mesmo conteúdo, e as críticas que os auxologistas fazem a esse tipo de avalia o, quando aplicadas individualmente. SíNTESE DOS DADOS: s o apresentados conceitos de referência, maturidade esquelética, alvo parental, escore z, baixa estatura, velocidade de crescimento, índice de massa corporal e seus pressupostos e limita es. CONCLUS ES: a avalia o do estado nutricional de popula es baseia-se em pontos de corte, partindo do pressuposto de que quem está abaixo ou acima daquele ponto apresenta um problema nutricional. A avalia o clínica baseia-se na idéia de variabilidade, e que esta pode ser tanto biológica quanto social, e cabe ao clínico estabelecer se a crian a está dentro ou fora de determinados parametros e se tem um crescimento, ou um diagnóstico nutricional, normais. Ao acompanhar o crescimento de uma crian a ou adolescente, o parametro mais importante a ser considerado é a velocidade de crescimento.

Abstract: objective: to compare the prevalence of pregnancy among adolescents and analyze trends in some social and biological variables among two cohorts of adolescent mothers in ribeir?o preto, brazil, during 1978/79 and 1994. methods: two cohorts of adolescent mothers were interviewed shortly after delivery, comprising 943 women in the first survey (1978/79) and 499 in the second (1994). both surveys covered more than 98% of births in all childbirth clinics. only singleton livebirths from adolescent mothers living in the municipality were included in the analysis. the chi-square test was used for statistical analysis, with a 0.05 significance level. results: the percentage of adolescent mothers increased from 14.1% in 1978/79 to 17.5% in 1994 (p<0.05), mainly due to an increase in deliveries in the 13-17 years age group. there was a reduction in the number of smokers and mothers with lower schooling. the number of prenatal care visits increased. there was also an increase in the proportion of single mothers, of those who were employed and got private delivery care. low birth weight and preterm birth rates remained unchanged for all of them. ceasarean section and forceps delivery rates increased substantially. mothers in the 13-17 years age group however showed twice as much premature and low birth weight children, a higher proportion of single mothers with lower schooling, and higher rate of forceps delivery. conclusions: some characteristics of the adolescent mothers in the 13-17 years age group were more unfavorable when compared to the 18-19 years age group. the characteristics of adolescent age groups need to be better understood and taken into account in the prenatal and delivery care planning.
