Abstract:
The aim of this dissertation is to examine the association between maternal underweight and preterm delivery. Using the MEDITECH database from Liverpool Womens Hospital we were able to look at women booking on for ante natal care between January 2005 and December 2007. This gave access to 23651 subjects. These subjects were grouped according to pre pregnancy BMI into five groups; severe-moderately underweight (BMI <18.5), moderate-mild underweight (BMI 18.6-19.9), acceptable weight (BMI 20-24.9), overweight (BMI 25-29.9) and obese (BMI >30). The gestation time of the pregnancy was classified into four groups with standard term delivery being >37 weeks gestation. The three classifications of premature delivery are; preterm delivery (32-36 weeks & 6 days), very preterm delivery (28-31 weeks and 6 days) and extremely premature delivery (<27 weeks and 6 days). Birth outcome was also investigated as associated with preterm delivery. Association between pre pregnancy maternal BMI and both gestation time and birth outcome were examined, with reference to maternal age, smoking behaviour and parity. Results: Women with pre pregnancy underweight were at increased risk of premature delivery. The risk of still birth was also slightly increased with severe-moderate underweight. There were also interesting findings on smoking and pre pregnancy underweight. Severe-moderate underweight (BMI <18.5) shows increased risk of both premature delivery and stillbirth. The more underweight BMI groups have a higher percentage of preterm deliveries. This is more pronounced in the severe-moderately underweight group with a total of 11.8% of infants born prematurely.
