<![CDATA[Miscarriage is one of the complications of first-trimester pregnancy that remains a significant cause of maternal morbidity and is influenced by various factors, one of which is maternal age. Although reproductive age is often associated with an increased risk of miscarriage, research findings across various regions still show inconsistencies. This study aims to analyze the relationship between maternal age and the incidence of abortion during the first trimester of pregnancy at the South Bolaang Mongondow Regional General Hospital (BolSel). The study employed a quantitative analytical design with a cross-sectional approach. The study sample consisted of 30 pregnant women in their first trimester, selected using total sampling. Data were obtained through a review of medical records and observation forms, then analyzed univariately and bivariately using the Contingency Coefficient test with a 95% confidence level. The results showed that the majority of respondents were aged 20–35 years (73.3%) and experienced anemia (93.3%), hypotension (53.3%), and spontaneous abortion (70.0%). Bivariate analysis results showed no significant association between maternal age and the incidence of abortion in the first trimester of pregnancy (p=0.392; r=0.244). These findings indicate that maternal age is not a major factor associated with the incidence of abortion in the study population, whereas other clinical factors such as anemia, hypotension, and a history of abortion are believed to play a greater role. The results of this study underscore the importance of comprehensive antenatal screening that focuses not only on maternal age but also on maternal clinical conditions to support the prevention of miscarriage and improve the quality of maternal health care.]]>
