Conclusion
In conclusion, utilising close to 1500 singleton term births from an ART
cohort, our results demonstrate that maternal or paternal overweight and
obesity increases infant birthweight independent to the BMI of the other
partner, with no additive effects seen if both parents were overweight
or obese. Further studies are warranted in both ART and general
population cohorts to support or refute our findings. Our results
highlight the notion for family unit preconception health
initiatives.
