Nosso objetivo foi investigar se havia diferen?a no PC de rec?m-nascidos (RNs) de m?es atendidas em maternidades p?blicas e privadas. Trata-se de um estudo transversal prospectivo realizado na MATERNIDADE ESCOLA JANUARIO CICCO (MEJC), estabelecimento de ensino da UFRN (MP) e dois hospitais privados (HP), no per?odo de dezembro/2008 a dezembro/2009. A an?lise dos dados foi feita utilizando os programas estat?sticos SPSS 17.0 e R 2.11.1, ANOVA e an?lise pos-hoc atrav?s do teste de Tukey. As curvas para o PC por idade gestacional (IG), estratificadas por tipo de parto, g?nero e sistema de sa?de foram constru?das utilizando o m?todo LMS. A amostra de estudo foi constitu?da de 2.847 RNs, de 34 a 42 semanas de IG, sendo 2.150 RNs da MEJC e 692 nascidos em HP. Nos dois grupos de RNs analisou-se as diferen?as entre os PCs m?dios, por IG, segundo g?nero, sistema de sa?de e tipo de parto. As novas curvas rec?m-criadas do PC foram validadas em amostras separadas, para todas as idades combinadas, para ambos os g?neros, sistemas p?blicos e privado, m?dia e ICs foram calculados para cada IG. Na an?lise da amostra geral, quanto aos g?neros, o PC m?dio no g?nero feminino foi 34,24 e no masculino 34,91 cm (p<0.001). Em rela??o aos sistemas de sa?de nos RNs, do sistema p?blico, o PC m?dio foi 34,49 cm, enquanto no sistema privado atingiu 34,90 cm (p<0.001). Quanto ao tipo de parto, o PC m?dio dos RNs de parto vaginal foi 34,12 cm, enquanto o de parto ces?reo obteve 34,81 cm (p<0.001). Os resultados permitem concluir que o PC m?dio dos RNs dos HPs apresentou-se maior do que os RNs avaliados na MEJC em todos os par?metros pesquisados. As curvas e os gr?ficos validados estatisticamente podem ser usados em regi?es de condi??es socioecon?micas semelhantes a nossa. Esse estudo apresentou perfil multidisciplinar com contribui??o de profissionais de v?rias ?reas do conhecimento cientifico, neonatologista, neuro infantil, enfermeira, estat?stico, seguindo os preceitos do Programa de P?s-Gradua??o em Ci?ncias da Sa?de da UFRN. / The measurement of the head circunference (HC) is of great importance from birth to young adult, especially during the first year of life when the head grows faster. Our objective was to investigate whether there was difference in HC of newborns (RNs) of mothers attended in public and private maternity hospitals. This is a cross-sectional study conducted at the Maternidade Escola Januario Cicco (MEJC), at the UFRN and two private hospitals (HP) from December 2008 to December 2009. Data analysis was performed using the statistical programs SPSS 17.0 and R 2.11.1, ANOVA and post-hoc analysis using the Tukey test, the curves for HC by GI, stratified by type of delivery, gender and were constructed using the LMS method. The study sample consisted of 2,847 newborns, from 34 to 42 weeks of gestational age (GI), of which 2,150 were born in the MEJC and 692 were born in PH. In the two groups of RNs the differences between the average PCs, by GI, according to gender, health system and type of delivery were analyzed. The newly created curves of the HC were validated in separate samples, for all ages combined, for both genders, and public and private systems, mean and CIs were calculated for each GI. In the analysis of the general sample, for the gender, the mean HC in the female gender was 34.24 and the male HD was 34.91 cm (p <0.001). Regarding health systems, in the public system the mean HD was 34.49 cm, while in the private system it reached 34.90 cm (p <0.001). Regarding the type of delivery, the mean HC of the vaginal birth RNs was 34.12 cm, the cesarean section was 34.81 cm (p <0.001). The results showed that the mean HD of the RNs of the HPs presented a HC greater than the RNs evaluated in the MEJC in all the parameters we surveyed. Statistically validated curves and charts can be used in regions with socioeconomic conditions similar to ours. This study presented a multidisciplinary profile with contribution of professionals from several areas of scientific knowledge, neonatologist, neuro child, nurse, statistician, following the precepts of the Graduate Program in Health Sciences of UFRN.
