The objective of the present study was to identify risk factors for preterm birth in São Luís, Maranhão, Brazil.

A total of 2,443 live births were randomly selected, excluding multiple deliveries and stillbirths. Preterm birth rate in São Luís was 12.7%.

“…Women with gestational age of 42 weeks or more showed greater chance of attending 7 or more prenatal visits in relation to those with up to 36 weeks of gestation. Aragon et al 24 , in a study carried out in São Luís, Maranhão, found prevalence of premature births (up to 36 weeks of gestation) of 23.3% among mothers who did not have access to prenatal visits, whereas those who attend 7 or more prenatal visits showed prevalence of only 4% (p < 0.001). Bezerra et al 25 , in a research conducted at the University Hospital of the Universidade de São Paulo (HU/USP), found that to attend up to three prenatal visits was associated with the occurrence of preterm birth (OR 4.26), compared with seven or more visits.…”

“…Vale lembrar que o pré-natal inadequado pode estar refletindo diferentes condições maternas como a dificuldade de acesso aos serviços de saúde, a não aceitação da gestação e outros indicadores de baixo nível sócio-econômico. Outros estudos observaram associação entre a não realização de pré-natal e o nascimento pré-termo 12,20,34 ; ou ao baixo número de consultas 35,36 .…”

“…No Brasil, há poucas pesquisas de base populacional sobre fatores de risco para nascimentos pré-termo, destacando-se os estudos realizados em São Luís (Maranhão) 11,12 e em Ribeirão Preto (São Paulo) 13 . Alguns estudos têm apontado altas prevalências de recém-nascidos pré-termo nos últimos anos: 10% no Rio de Janeiro 14 , 13,6% em Ribeirão Preto em 1994 15 17 .…”

“…A Brazilian study shows that the highest rates of preterm birth are seen in relatively affluent areas, where cesarean sections are more frequent 27 . However, a population study failed to identify an association with type of delivery 28 . Villar et al 29 in the 2005 WHO global survey on maternal and perinatal health, studied all women delivering in a 3-month period in 120 hospitals from eight countries in Latin America.…”
