Background: Hypertensive disorders of pregnancy are a frequent situation\nand involve about 8% - 10% of pregnancies. Extremes maternal ages have\nbeen associated to hypertensive disorders of pregnancy. In Africa, even if\nmotherhood in teens is common, pregnancy at advanced age is getting more\nand more frequent. Objectives: To investigate the relation between maternal\nage and hypertensive disorders of pregnancy. Methods: A retrospective cohort\nstudy over 8 years was conducted in a suburb setting in Dakar, Senegal.\nThe participants were divided into two groups based on the occurrence of\nhypertensive disorders of pregnancy (HDP). Data were extracted from\nE-Perinatal, our electronic medical recording system and analyzed using SPSS\n20.0 and R Studio software version 1.1.383.51. Maternal and perinatal outcomes\nwere assessed over 3 age groups: <19 years, >34 years and 19 - 34 years\nold. Results: The study included 2226 cases of HDP out of 36,499 deliveries\nleading to an incidence of 6.1%. The proportions of nulliparous, multiple\npregnancies and maternal diabetes were higher in women with HDP. The risk\nof high blood pressure among mothers aged 35 years and over was 1.6 times\nas high as the risk among those aged 19 - 34 years at a significant level before\nand after adjusting for third factors i.e. parity, multiple pregnancy and diabetes.\nHowever, adolescents were found to have the same risk compared to\ntheir counterparts aged 19 - 34 years. Risk of eclampsia was 4 times greater\namong adolescent girls. Conclusion: Advanced maternal age greater than or\nequal to 35 years is a risk factor for high blood pressure. There is no extra risk\nin adolescent girls with regard to high blood pressure; however, risk of eclampsia\nwas higher in this group.
