The effects of vaginal bleeding during first and second trimester on pregnancy outcomes was assessed in a hospital-based population of 268 non-diabetic women. The group of non-bleeders comprised 173 females whereas, there were 71 females with first and 24 with second trimester bleeding. Fetal loss (abortion) occurred in 34% of first trimester and 25% of second trimester bleeders. Low birth weight and preterm delivery were significantly associated with second trimester haemorrhage. The results suggest that first and second trimester vaginal bleeding correlates with adverse infant outcomes.
在一家医院的268名非糖尿病女性群体中，评估了孕早期和孕中期阴道出血对妊娠结局的影响。未出血组有173名女性，而孕早期出血的有71名女性，孕中期出血的有24名女性。孕早期出血者中有34%发生胎儿丢失（流产），孕中期出血者中有25%发生胎儿丢失。低出生体重和早产与孕中期出血显著相关。结果表明，孕早期和孕中期阴道出血与不良婴儿结局相关。
