To compare prenatal care coverage between adolescent (early and late) and adult pregnant women in Iquitos, Peru.
A random sample of 4467 birth records was collected. Multivariate analyses were performed to compare prenatal care coverage in all adolescent (10-14 years, 15-19 years) and adult (>or=20 years) age groups and then for primiparous women only.
The mean number of visits was 5.0 for adolescents aged 10-14 years, 6.1 for adolescents aged 15-19 years, and 6.2 for women aged 20 years or older. For primiparous women, the means were 5.1, 6.2, and 6.8, for the respective age groups. Both the proportion attending and the number of prenatal visits were significantly lower in primiparous adolescents aged 10-14 years than in primiparous women aged 20 years or older (aOR 0.25; 95% CI, 0.10-0.62 and aRR 0.83; 95% CI, 0.74-0.94, respectively).
All women attended prenatal care more frequently than the WHO's recommended 4 visits; however, early adolescents attended significantly less often than late adolescents or adult women. Further study of this inequality is warranted to adequately inform local health services.
比较秘鲁伊基托斯青少年（早期和晚期）和成年孕妇的产前保健覆盖率。
随机抽取了 4467 份分娩记录进行分析。采用多变量分析比较了所有青少年（10-14 岁，15-19 岁）和成年（≥20 岁）年龄组的产前保健覆盖率，然后仅对初产妇进行了比较。
10-14 岁青少年的平均就诊次数为 5.0 次，15-19 岁青少年为 6.1 次，20 岁及以上妇女为 6.2 次。对于初产妇，相应年龄组的平均值分别为 5.1、6.2 和 6.8。初产青少年（10-14 岁）的就诊比例和就诊次数均明显低于 20 岁及以上的初产妇（aOR 0.25；95%CI，0.10-0.62 和 aRR 0.83；95%CI，0.74-0.94）。
所有女性接受产前保健的频率均高于世界卫生组织推荐的 4 次就诊，但早期青少年的就诊频率明显低于晚期青少年或成年女性。需要进一步研究这种不平等现象，为当地卫生服务提供充分的信息。
