Statistical Retrospective Analysis of Spontaneous Abortions in Sidi Bel Abbes Region
Objective: The aim of our study was to identify modifiable risk factors for miscarriage and to estimate the preventable proportion of miscarriages that could be attributed to these risks. Materials and Method: We carried out an epidemiological study of pregnancy loss in the Sidi Bel Abbes region from 2010 to 2015, with a total of 54720 livebirths and 4349 of spontaneous abortions (SA). The risk of spontaneous abortion related to the fetal loss age, maternal age; parity and previous spontaneous abortions was studied. Results: The rate of spontaneous abortions varies between 7% and 9% and appears to remain constant over the six years, with an average incidence of 8%. We also observed a significant increase in the incidence of SA with the increase in maternal age. 77% of SA occurred before 12 weeks of gestation. The peak incidence occurred during the second month of pregnancy, between 6th and 10th, the rate of AS is the highest among primigests. The incidence of SRA in our study is within the range suggested by these different studies, with a SRA rate of 5%. Fetal loss is high in women in their late 30s or older, irrespective of reproductive history. Conclusion: The fact remains that the risk factors remain the same, namely, the increase in maternal age (inducing an increase in chromosomally unbalanced designs) and primigestity.
