To examine the association between maternal Body Mass Index (BMI), Mediterranean diet adherence, and the risk of PTB and recurrent PTB.
Study Design:
A prospective cohort of 462 singleton pregnancies at a tertiary center and affiliated clinics (IRB#0390-20-SOR), including women with and without prior spontaneous PTB, was studied. Maternal BMI was recorded at recruitment and delivery. Mediterranean diet adherence was assessed via a validated short questionnaire. PTB incidence was compared across BMI categories and diet adherence categories, with stratified analysis by PTB history.
Results:
The study included 462 women: 257 (55.6%) with and 205 (44.4%) without a history of PTB. Of these, 81 (18.1%) had low adherence to the Mediterranean diet (score ≤5/17), 35 (7.6%) were underweight (BMI< 18.5), and 253 (54.8%) had normal weight. Recurrent PTB occurred in 22.5% (n=55), initial PTB in 4.3% (n=8). Underweight women were more likely to have PTB (42.9% [15] vs. 20.6% [88], OR=2.89, 95% CI: 1.15–7.26). Low diet adherence was associated with increased PTB risk (26% vs. 11.9%, OR=2.72, 95% CI: 1.5–4.93) and recurrent PTB (42% vs. 18.1%; OR=3.31, 95% CI: 1.66–6.62; Figure). In adjusted models, low diet adherence increased PTB risk by 19.9% per one-point decrease (AdjOR=1.20, 95% CI: 1.02–1.40, p=0.025). Among women with prior PTB, underweight increased recurrent PTB risk (adjOR=2.69, 95% CI: 1.04–6.93, p=0.040), while low adherence increased it by 25.5% per one-point decrease (AdjOR=1.26, 95% CI: 1.05–1.49, p=0.011) (Table).
Conclusion:
Low adherence to Mediterranean diet is a risk factor for both PTB and recurrent PTB. These findings emphasize the need for tailored nutritional and weight management strategies to mitigate the risk of PTB and recurrent PTB.
