Resumo:
O Brasil tem uma das maiores taxas de partos cesáreos do mundo, e esse valor tem aumentado anualmente. O presente estudo teve como objetivo analisar possíveis mudanças na data de nascimento decorrentes desse aumento. Foram obtidos os dados dos 1.933.137 nascidos vivos ocorridos no Município de São Paulo entre 2001 e 2010, divididos segundo tipo de parto e data exata de nascimento. Em 2001, a taxa de cesarianas foi de 48,9%, passando a 56,8% em 2010. O dia da semana com menor número de nascimentos (domingo) aumentou a diferença em relação aos outros dias de 111,4 (IC95%: 101,7 - 121,0) em 2001 para 143,1 (IC95%: 135,0 - 151,3) em 2010. Os dois dias com menos nascimentos (Natal e Dia de Finados), apresentaram diferença estatisticamente significativa em relação aos outros dias do ano (p<0.05) durante praticamente todo o período (a exceção foi o Dia de Finados em 2009). A data com o maior número de nascimentos (Dia Internacional da Mulher) apresentou diferença significativa em 2005 e 2010. O aumento no número de partos cesáreos tem tido efeito significativo na data de nascimento, o que pode trazer consequências no planejamento administrativo de instituições de saúde.

Abstract:
Brazil has one of the highest rates of caesarean births, and the number has been growing annually. The present study aimed to test its possible consequences on the date of birth. The 1,933,137 live births that occurred in São Paulo, Brazil, from 2001 to 2010 were analyzed by type of delivery and exact date of birth. In 2001, 48.9% of all births were caesarean, increasing to 56.8% in 2010. During this period, the difference between the number of births occurring in Sundays (the day of the week with the lowest number) increased from 111.4 (95%CI: 101.7 – 121.0) in 2001, to 143.1 (95%CI: 135.0 – 151.3) in 2010. The two dates with the lowest number of births (Christmas and Day of the Dead), had a statistically significant (p<0.05) difference from the other days of the year during most of the period (the exception being the Day of the Dead in 2009). The date with the highest number of births (International Women’s Day) had a statistically significant difference in 2005 and 2010. The increase in the number of caesarean births has had an important impact on the date of birth, which could lead to effects on the administrative planning of health institutions.
