The statistical test obtained (p-value) = 0.003 (< ɑ = 0.05) which means there is a significant relationship between maternal age and the incidence of abortion. The results of the chi-square statistical test to determine the relationship between parity and the incidence of abortion were obtained (p-value) = 0.043 (< ɑ = 0.05) which means there is a significant relationship between maternal parity and the incidence of abortion. Maternal age < 20 years indicates a physical and psychological condition that is not yet ready, age > 35 years indicates a sign that reproductive organs are not working optimally such as those of productive age, high parity indicates how the condition of the uterine muscles is getting weaker and unable to maintain pregnancy, so women need to give education before planning a pregnancy, during pregnancy, and spacing of pregnancies so that women are better prepared and able to maintain their pregnancies to avoid abortion.]]>
