title: [Perinatal mortality in the municipality of Salvador, Northeastern Brazil: evolution from 2000 to 2009].
abstract: OBJECTIVE
  To describe and analyze the evolution of perinatal mortality with regards the scale and extent of the problem.
  
  
  METHODS
  A descriptive time trend study with 10,994 perinatal deaths to mothers living in Salvador, Bahia, Northeastern Brazil, with a gestational age of ≥ 22 weeks, newborn age of up to six days and birth weight of 500 grams or more, recorded from 2000 to 2009. Data from the Information Systems on Live Births and Mortality of DATASUS/Ministry of Health available on the website were used. Rates of perinatal and fetal mortality per 1,000 births and early neonatal mortality per 1,000 live births were calculated. The Pearson's Qui-square test for differences in proportions, sequence (runs) test, the calculation of moving averages and linear coefficient of determination (R²) were used for trend analysis. The Wigglesworth classification of causes of death was used.
  
  
  RESULTS
  The rates of perinatal mortality showed a decreasing trend, of -42.0% in the period (from 33.1 (2000) to 19.2 (2009)), with a greater share of rates of neonatal mortality (-56.3%). Fetal mortality accounted for a large proportion (61.9%) of rates of perinatal mortality in 2009. The classification of deaths showed the following most frequent causes of perinatal deaths: intrapartum asphyxia (8.8/1,000), immaturity (7.1/1,000) and congenital malformations (1.3/1,000).
  
  
  CONCLUSIONS
  Perinatal mortality remains high despite the downward trend, and the predominance of fetal mortality indicates recent changes in the profile of causes of death and impact on prevention activities. The quality of prenatal care with risk control and improving care during the delivery may reduce the occurrence of preventable causes of death.
