ObjectiveTo evaluate the impact of obesity on the decision to delivery interval.Study designWe compared the interval to delivery in normal, obese (BMI 30–40 kg/m2), and morbidly obese (BMI over 40 kg/m2) women. In a planned sub-analysis, we evaluated those who underwent emergency cesarean.ResultsWe included 447 (25.3%) subjects: 157 normal, 200 obese, and 90 morbidly obese. We found no significant difference in the decision to delivery interval, mean ± SD (minutes): 39 ± 24, 44 ± 28, and 46 ± 28, p = 0.10. In the setting of emergency delivery we did find significantly prolonged intervals: 18 ± 8, 23 ± 16, and 30 ± 19 in non-obese, obese, and morbidly obese, respectively, p = 0.04.ConclusionWe found similar decision to delivery intervals in women of varying BMI. In the setting of emergency cesarean delivery, we found increasing BMI to be associated with significant delays to delivery.
