To identify the main socioeconomic, demographic, anthropometric and behavioral characteristics, and pregnancy outcomes of adolescent pregnancy and to assess health services used by pregnant adolescents.
Data were collected from a cross-section of 2,429 deliveries by women residing in the municipality of São Luís, Brazil, of which 94% were hospital births. Women were categorized into six age groups. The two groups of teenagers (under 18 and 18-19 years) were compared to four groups of older women. Comparison was also made between the two teenage groups. The chi-square test was used to compare proportions and prevalence ratio was used as an effect measure.
Of 2,429 women, 714 (29.4%) were adolescents. Their specific fertility coefficient was higher than in other regions of the country. Adolescents showed lower socioeconomic and reproductive conditions than older women and a higher proportion of inadequate prenatal care. The majority had no partner. They had the lowest percentages of caesarean section and smokers.
Despite their equally unfavorable socioeconomic situation, 18-19 year-old adolescents had pregnancy outcomes comparable to the age group 25-29, whereas those under 18 had the highest proportions of low birth weight, preterm birth, and infant mortality rate. This suggests that biologic immaturity may be associated with adverse pregnancy outcomes.
确定青少年妊娠的主要社会经济、人口统计学、人体测量学和行为特征以及妊娠结局，并评估怀孕青少年使用的卫生服务。
数据收集自巴西圣路易斯市居住的女性的2429例分娩横断面，其中94%为医院分娩。女性被分为六个年龄组。将两组青少年（18岁以下和18 - 19岁）与四组年龄较大的女性进行比较。两组青少年之间也进行了比较。卡方检验用于比较比例，患病率比用作效应量度。
在2429名女性中，714名（29.4%）为青少年。她们的特定生育率高于该国其他地区。青少年的社会经济和生殖状况低于年龄较大的女性，产前护理不足的比例更高。大多数人没有伴侣。她们的剖宫产率和吸烟者比例最低。
尽管18 - 19岁青少年的社会经济状况同样不利，但她们的妊娠结局与25 - 29岁年龄组相当，而18岁以下青少年的低出生体重、早产和婴儿死亡率比例最高。这表明生物不成熟可能与不良妊娠结局有关。
