Estudo epidemiológico do peso ao nascer a partir da Declaração de Nascido Vivo

The highest proportion (10.4%) of low birth weight infants (weight less than 2,500 g) occurred in Itararé, the city with the highest infant mortality rate in the State, the overall proportion being 7.5%. Significant statistical associations between low birth weight and sex (female), gestational age (less than 37 weeks), mother's age (adolescent and 35 or more years of age) and parity were detected. The use of Birth Certificates in epidemiological and public health studies is highly recommended because of their validity, great importance and high coverage.
