A comprehensive study published in the Canadian Medical Association Journal sheds light on the heightened risk of stillbirth associated with obesity, especially as pregnancy progresses toward term. Led by Dr. Naila Ramji, a high-risk pregnancy specialist, the research underscores the urgent need for tailored interventions to mitigate this risk.
Drawing on data from the Better Outcomes Registry and Network, researchers analyzed over 680,000 singleton births in Ontario between 2012 and 2018, revealing a concerning trend: individuals with obesity face a significantly elevated risk of stillbirth, particularly as gestational age advances.
The findings indicate that those with class I obesity (BMI 30–34.9 kg/m2) have double the risk of stillbirth at 39 weeks gestation compared to individuals with normal BMI. Moreover, the risk escalates dramatically for those in obesity classes II and III, with a more than fourfold increase in risk at 40 weeks gestation.
Importantly, the study highlights the need for earlier delivery in at-risk populations, with Dr. Ramji advocating for timely referral and increased surveillance closer to term. This proactive approach could potentially mitigate the risk of stillbirth and improve outcomes for pregnant individuals with obesity, especially those with additional risk factors.
However, the study also raises concerns about potential biases in prenatal care. Dr. Naomi Cahill, in a related editorial, emphasizes the importance of a nuanced approach in counseling patients with obesity. Highlighting the harmful impact of weight-related stigma and discrimination, Dr. Cahill underscores the need for respectful, stigma-free prenatal care to ensure positive maternal and fetal outcomes.
Overall, the study calls for heightened awareness and tailored interventions to address the significant risk of stillbirth associated with obesity, emphasizing the importance of compassionate and equitable prenatal care for all pregnant individuals.
