A case-control study was conducted to assess the effectiveness of antenatal care in preventing intrauterine growth retardation (IUGR) and low birth weight due to preterm delivery (PD), using data from 1837 births which took place in 25 hospitals in Mexico City during 1984. Women with an inadequate number of visits for gestational age had 63% greater odds of IUGR (95% CI: 1.01, 2.65) and 51% greater odds of PD (95% CI: 1.02, 2.23) than women with an adequate number. The content of antenatal visits showed no independent effect on the prevention of IUGR. Women having had poor content showed a PD OR of 1.76 (95% IC: 1.33, 2.34). An important reduction in the incidence of births with IUGR and PD could be expected if women could attend an adequate number of antenatal visits (11 and 9% reductions, respectively). Eighteen per cent of the PD births would probably be prevented if antenatal care could include at least six procedures: blood pressure, height and weight, urine and blood samples, and pelvic examination.
一项病例对照研究利用1984年在墨西哥城25家医院发生的1837例分娩数据，评估产前护理在预防因早产（PD）导致的宫内生长受限（IUGR）和低出生体重方面的有效性。与产检次数充足的女性相比，孕周产检次数不足的女性发生IUGR的几率高63%（95%置信区间：1.01, 2.65），发生PD的几率高51%（95%置信区间：1.02, 2.23）。产前检查的内容对预防IUGR没有独立影响。产检内容较差的女性发生PD的比值比为1.76（95%置信区间：1.33, 2.34）。如果女性能够进行充足次数的产前检查（分别减少11%和9%），预计IUGR和PD分娩的发生率会显著降低。如果产前护理至少能包括六项检查程序：血压、身高和体重、尿液和血液样本以及盆腔检查，那么18%的PD分娩可能会得以预防。
