The relationship between intrapartum amniotic fluid index, fetal distress and fetal acidemia.

Blood pressure ≥ 140/90 (OR = 1.3), age ≥ 35 years (OR = 1.2), pure African race (OR = 1.3) and group A blood (OR = 1.3), have all appeared to slightly increase the risk of recurrent miscarriage. As the study was very small, a larger study is needed to either confirm or refute any possible causal relationship. Age < 35 years (OR = 0.89), Arabic race (OR = 0.7), history of contraceptive use (OR = 0.06), blood group other than group A (OR ranging from 0.78 to 1.08), and Rhesus factor positivity or negativity (OR = 0.90 and 1.09) are not associated with increased risk of recurrent miscarriage. Contrary to the belief of many Sudanese women, contraceptive use does not increase the risk of recurrent miscarriage. The presence of ACL antibodies is a risk factor for recurrent miscarriage among Sudanese women (OR = 2). It is therefore, important to offer women with recurrent miscarriage investigation for APL syndrome. Ethnic origin seems to play little or no role in the prevalence of APL syndrome. Most of the other risk factors did not seem to increase the risk of recurrent miscarriage significantly, however, more studies are needed to evaluate some risk factors that were shown to increase the risk slightly such as age, blood pressure and blood group A.
