Exposure: Women’s before-pregnancy frame mass index
Outcome: Severe maternal sickness or demise, outlined as life-threatening stipulations or stipulations resulting in critical penalties, or headaches requiring in depth care unit admission, or maternal demise all the way through the hospitalization.

24.nine extra for overweight girls with a BMI of 30.Zero-34.nine;
35.eight extra for overweight girls with a BMI of 35.Zero-39.nine;
61.1 extra for overweight girls with a BMI of 40 or larger.
Study Limitations: Despite the huge learn about dimension, demise and a couple of very uncommon headaches befell in just a small collection of girls so to assess associations between dangerous BMI and those particular results. Information on BMI used to be self-reported and probably misguided.
