Abstract Introduction Occiput posterior (OP) position rates at birth are 5%–8% in studies mainly comprising white European women. The anthropoid pelvis is common black African This pelvic shape has a narrow anterior segment and an ample room posteriorly. fetal head wider posteriorly, the OP may be favorable women with shape. We aimed to examine rotation ultrasound longitudinally during active phase of labor sub‐Saharan population. also associations between position, delivery mode, duration labor. Material Methods study was conducted Kilimanjaro Christian Medical Centre Moshi, Tanzania from 19th November 2023 13th April 2024. Women single fetus cephalic presentation, gestational age >37 weeks, without previous or pre‐labor cesarean section were eligible. Fetal classified as occiput (OA) 10 2 o'clock, transverse (OT) 3 9 4 8 o'clock. Results participants comprised 215 positions admission, first second stage presented graphical figure. In all, 65/215 (30.2%) fetuses 59/204 (28.9%) stage, 38/210 (18.1%) 35/215 (16.3%) delivered position. 25/92 (27.2%) nulliparous 10/123 (8.1%) parous operative rate 10/157 (6.4%) assessed OA (six four vacuum extractions), 28/48 (58.3%) non‐OA group (27 one extraction) ( p < 0.01). hazard ratio for 0.26 (95% CI 0.13–0.52) versus 0.25 0.12–0.52) Conclusions persistent higher than previously reported, intervention nine time stage.
