To study demographic and health related variables included in the municipal birth registry. Differences among municipal districts are assessed, as an approach to the study of inequalities in pregnancy, in birth and in its care.
Observational study, based on secondary utilization of vital statistics data. SITE: The city of Barcelona (Catalonia, Spain), for the 1990-1991 years.
Births from women who are city residents.
Births concentrate around maternal ages of 25-29 years and 30-34. Adolescent mothers (less than 20 years) represent only a proportion of 1.9% of all births, and births from women above 34 years 13.7%, although only 2.1% of all births are from mothers above 40 years of age. Low birth weight (less than 2,500 g) occurs in 5.6% of all births. Preterm births (less than 37 weeks) occur in 4.7% of all deliveries. Teen age fertility, births to women above 34 years, low birth weight and preterm deliveries are compared across districts. Overall, four out of ten women use a public hospital for delivery, but this varies greatly among districts. There is no information on the father for 1.6% of all births.
The completeness of this information source is high and the municipal registry is a useful database for the analysis of inequalities in small areas, using health related indicators which have higher frequency than more traditional indicators based on rare events (such as infant mortality). Differences among areas are found, related to life conditions and to prenatal and birth care.
研究市政出生登记中包含的人口统计学和健康相关变量。评估市辖区之间的差异，以此作为研究妊娠、分娩及其护理方面不平等现象的一种方法。
基于生命统计数据二次利用的观察性研究。
西班牙加泰罗尼亚的巴塞罗那市，时间为1990 - 1991年。
城市居民女性的分娩情况。
分娩主要集中在25 - 29岁和30 - 34岁的产妇年龄段。青少年母亲（小于20岁）仅占所有分娩的1.9%，34岁以上女性的分娩占13.7%，尽管40岁以上母亲的分娩仅占所有分娩的2.1%。低体重儿（小于2500克）占所有分娩的5.6%。早产（小于37周）占所有分娩的4.7%。比较了各辖区的青少年生育率、34岁以上女性的分娩、低体重儿和早产情况。总体而言，十分之四的女性在公立医院分娩，但各辖区差异很大。所有分娩中有1.6%没有父亲的信息。
该信息来源的完整性较高，市政登记是一个有用的数据库，可用于利用比基于罕见事件（如婴儿死亡率）的更传统指标频率更高的健康相关指标，分析小区域内的不平等现象。发现了与生活条件以及产前和分娩护理相关的地区差异。
