This study aims to investigate the relation between age and certain diseases that cause maternal mortality in North Darfur Province in Sudan during the reproductive age range of 14-49 years, encompassing the period of pregnancy, childbirth, and up to 42 days postpartum. The study is based on the analysis of demographic age groups and healthcare data, with special focus on blood pressure disorder, obstetric hemorrhaging, unsafe abortion, and sepsis among deceased mothers in hospitals and health centers within the study area during the year 2022. The study sample comprises a total of 180 cases. Chi-square test was employed to assess the degree of independence between the age variable and the health variables associated with fatal diseases. The findings show that age is not an independent factor in the causes of death. The findings indicate a correlation between different age categories, various blood pressure abnormalities, obstetric hemorrhage, and unsafe abortion in deceased women, with a statistical significance level of 0.000. However, the statistical significance level between age and sepsis was found to be 0.002.
