Introdução: O aumento da taxa de cesarianas, tem sido levada nos Ășltimos anos
cada vez mais em consideração pela investigação cientĂfica, por causa de ser mais onerosa ao erĂĄrio pĂșblico, e tendo maior risco tanto para a mĂŁe como para o bebĂ©. Neste estudo pretende-se efetuar uma pesquisa multifatorial, atravĂ©s de tĂ©cnicas estatĂsticas multivariadas, que possa explicar a preferĂȘncia da grĂĄvida pelo parto por via cesariana.
MĂ©todos: Assente numa amostra de 245 grĂĄvidas (com 1 omisso, dividida em 2 grupos, G0 - PreferĂȘncia pelo parto vaginal e G1 - PreferĂȘncia pelo parto cesariana, sendo
o n0 = 190 e o n1 = 54 respetivamente), inquiridas no Centro Materno-Infantil do Norte,
pertencente ao Centro Hospitalar do Porto, foi executada, inicialmente uma anålise exploratória dos dados, seguindo-se de uma anålise de componentes principais nas questÔes com
natureza ordinal (escala de likert), com propósito de reduzir a complexidade da informação
numa estrutura mais simples. Posteriormente foi desenvolvida uma regressĂŁo logĂstica com
todas as variĂĄveis, incluindo as componentes criadas pela anĂĄlise de componentes principais,
para identificar os possĂveis fatores preditivos para a preferĂȘncia do tipo de parto.
Resultados: A anĂĄlise de componentes principais, identificou 3 componentes para cada
grupo, sendo denominadas por, vantagens do parto para a MĂŁe, medo do parto e preocupação com o bebĂ©. Pela regressĂŁo logĂstica foram apurados fatores como idade (p < 0.05),
obtenção de informação junto do médico familiar/obstetra (p < 0.05), obtenção de informação junto do marido/parceiro/amigo (p < 0.05), vantagens do parto para a Mãe (p < 0.01),
medo do parto (p < 0.01) e preocupação com o bebé (p < 0.05), que são significativos para
opção pelo tipo de parto.
ConclusĂŁo: Nesta pesquisa, com atenção Ă assimetria dos tamanhos dos grupos e sendo a amostra total apenas do sector pĂșblico, foram identificados fatores especĂficos que podem ajudar na explicação da problemĂĄtica, tais como a idade (Odds Ratio (ËÎČ) = 1.12,p < 0.05), medo do parto (Odds Ratio (ËÎČ) = 1.04,p < 0.01) e a preocupação com o bebĂ© (Odds Ratio(ËÎČ) = 1.02,p < 0.01).
Purpose: The increase in the rate of cesarean sections, has been increasingly taken into account by scientific research in recent years, because it is more costly to the public purse, and has a greater risk for both the mother and the baby. In this study, we intend to carry out a multifactorial research, using multivariate statistical techniques, which may explain the preference of pregnant by cesarean delivery. Methods: Based on a sample of 245 pregnant (with 1 missing, divided into 2 groups, G0 - Preference for vaginal delivery and G1 - Preference for cesarean delivery, with n0 = 190 and n1 = 54 respectively), inquired at the Centro Materno-Infantil do Norte, belonging to the Centro Hospitalar do Porto, initially an exploratory analysis of the data was performed, followed by a principal component analysis in the questions of ordinal nature (likert scale), with the purpose of reducing the complexity of the information in a simpler structure. Subsequently, a logistic regression with all variables was developed, including the components created by the principal component analysis, to identify possible predictive factors for the type of delivery preference. Results: The principal components analysis, identified 3 components for each group, which were denominated as: advantages of childbirth for the Mother, fear of childbirth and concern with the baby. The logistic regression identified age (p < 0.05), obtaining information from the family doctor/obstetrician (p < 0.05), obtaining information from husband/partner/friend (p < 0.05), advantages of childbirth for the Mother (p < 0.01), fear of childbirth (p < 0.01) and concern with the baby (p < 0.05), that are significant for choosing the type of delivery. Conclusion: In this work, taking into account that the sample was only from a public sector and that the size of the groups was asymmetric, specific factors were identified that can help to explain the reasons behind the preference for the type of delivery, such as age (Odds Ratio ( ËÎČ) = 1.12,p < 0.05), fear of childbirth (Odds Ratio ( ËÎČ) = 1.04,p < 0.01) and the concern for the baby (Odds Ratio ( ËÎČ) = 1.02,p < 0.01).
