Pdf Summary

This study analyzed data from a large birth registry to investigate the effect of demographic changes on the mode of delivery. The researchers looked at 27,729 singleton deliveries between 2004 and 2014, excluding multiple deliveries. The main outcomes measured were age, BMI, and mode of delivery. The study found that the number of singleton deliveries increased over the eleven-year period, with an annual increase from 2,093 in 2004 to 2,778 in 2014. The mean age of the mothers at delivery also slightly increased from 31.1 years in 2004 to 31.5 years in 2014. The study also observed an increase in BMI before pregnancy and at delivery over the same time period. The researchers noted that the prior mode of delivery had the strongest influence on the current mode of delivery. In a high-risk group of women for developing pelvic floor disorders later in life, the rate of C-section was found to be over 50%. The study concluded that while age and BMI increased significantly, the clinical relevance of these changes might be low. The mode of delivery was primarily influenced by prior deliveries. In high-risk situations, such as maternal height below 160cm and fetal weight above 4kg, the rate of C-section was higher than 50%.
