Decreased Nutrient Intake Is Associated With Premature Cervical Remodeling

Area of Science:

• Obstetrics and Gynecology
• Nutritional Science
• Maternal-Fetal Medicine

Background:

• Cervical remodeling is a critical factor in preterm birth.
• Understanding the influence of maternal nutrition on cervical changes is essential for improving pregnancy outcomes.

Purpose of the Study:

• To investigate the direct association between nutrient consumption and cervical remodeling during pregnancy.
• To identify specific nutrients that may influence the risk of premature cervical changes.

Main Methods:

• A longitudinal descriptive study was conducted with 47 pregnant African American women.
• Dietary intake was assessed using the Block brief food frequency questionnaire at multiple gestational points.
• Quantitative ultrasonic attenuation estimates were used to monitor cervical changes throughout gestation.

Main Results:

• Two subpopulations were identified: those at risk (n=36) and at less risk (n=11) for premature cervical remodeling.
• Women in the less-risk group showed higher consumption of recommended dietary reference intakes for calcium, vitamin A, folate, vitamin E, zinc, and vitamin D.
• Significantly higher intake of vitamin E, calcium, and zinc was observed in the less-risk group compared to the at-risk group.

Conclusions:

• Specific nutrients, notably zinc, calcium, and vitamin E, appear crucial for cervical health.
• Adequate intake of these nutrients may help inhibit premature cervical remodeling, potentially reducing the incidence of preterm birth.
