Abstract

Objective: To describe the trend in annual live birth in Chile between 2000 and 2009, as well as the main descriptive statistics and health indicators associated. Methods: We performed a descriptive analysis form the database provided by the Department of Statistics and Information of the Chilean Ministry of Health. Data of 2.400.000 deliveries were analyzed from 2000 and 2009. We analyzed live births, maternal, fetal, infant mortality, as well as main descriptive characteristics by year. Results: The total of live births in Chile has progressively increased after the year 2005 until 2009 (+ 9.7%). The early neonatal, late neonatal, post neonatal mortality and mortality infant were 3.86, 1.18, 2.54 and 7.58 per 1000 live births in 2009, showing a decrease of 13.5; 8.4; 16.2; 13.7% respectively compared to 2000. Maternal mortality declined a 13.2% from 19.7 to 17.1 × 100.000 births in the same period. Prematurity (<37weeks) increased significantly in a 20.82% (5.96% to 7.2%). The biggest change is observed at late preterm birth 32-33 and 34-36 weeks (increase of 18% and 32% respectively). The rate of multiple births (two) significantly increased also in a 11%, from 1.66 to 1.84 × 100.000 birth. Conclusion: During the study period, a significant increase of total births, the percentage of primipare and mothers over 40 years was observed. It's also shown an increase in prematurity, low birth weight and the percentage of multiple pregnancies. The observed changes are associated with improved neonatal indicators.
