Abstract

The study was undertaken to compare infectious morbidity and trial of labor (TOL) success stratified by weight in women. Vaginal birth after cesarean section (VBAC) candidates were divided into groups based on prepregnancy weight: group I, 70 (<200 pounds); group II, 70 (200-300 pounds); and group III, 69 (>300 pounds). The TOL success rate was 81.8% in group I compared with 57.1% in group II and 13.3% in group III (P =.001). The overall infectious morbidity was significantly greater in the obese women 39% (P =.001) compared with the average women at 11.4% and the lean women at 5.7%. Infectious morbidity is increased and VBAC success is reduced in patients who weigh more than 300 pounds.
