Background
Previous data demonstrated an increased incidence in congenital lung malformations (CLM) and hypothesised a link with maternal obesity.
Method
A retrospective case-control study (1994-2017) including all cases of CLM and matched controls (N=114 pregnancies). For each diagnosis of a baby diagnosed antenatally with CLM, two controls were selected. Primary outcome measure was mean Body Mass Index of women of affected pregnancies.
Results
The women in affected pregnancies had a greater BMI (26.7 ±5.2kg/m2 (n=38)) than the control women (24.6±4.7 kg/m2 (n=76)) (p=0.03). 60.5% (n=46) of women in the control group and 39.5% (n=15) women in the CLM group had a normal BMI (<25kg/m2). Women with a BMI > 25kg/m2 had a 1.53 relative risk (RR) of having an affected baby (p=0.02, 95% CI 1.05-2.24).
Conclusion
Obesity is not associated with increased rates of CLM. There is a small clinical difference in the BMI of women affected by CLM.
