摘要：Framework: The low birthweight is a risk factor for neonatal morbidity and mortality and a general indicator of health status of a population. It can be associated to low levels of socioeconomic development, prenatal care and maternal charateristics. Objectives: Analyze the influence of sociodemographic, obstetric and prenatal care variables to low birthweight. Participants: 1846 post-partum women, where only 161 had newborns with low birthweight. Methods: This is a wide-ranging, descriptive-correlacional and forward-looking study with a non-probable intentional sample. It was used a questionnaire, applied between March 2010 and May 2012, in 26 Portuguese institutions of public health. Results: The low birthweight was associated: ≥ 41 weeks (p=0,000), without obstetric risk (p=0,001), without obstetric risk/unplanned pregnancy (p=0,036), obstetric risk/maternal age risk (p=0,007), without sociodemographic risk/gestacional age without risk (p=0,000), sociodemographic risk/gestacional age without risk (p=0,007), risk on prenatal care/maternal age risk(p=0,020), prenatal care without risk/gestacional age without risk (p=0,000), maternal age risk/risk number of pregnancies (p=0,021), low education/income ≤1000€(p=0,036), low education/unemployment (p=0,044), risk number of children/gestational age without risk (p=0,000), pregnancy diseases /gestational age without risk (p=0,000), previous diseases/gestational age without risk (p=0,000), and with a margin error of 10%, low education (p=0,074) and unplanned pregnancy (p=0,089). The prevalence of LBW was 8.7%. Conclusion: The determination of the factors that contribute to the appearance of low birthweight is essential for the planning, implementation and development of actions related to maternal and children health.
