Which factor is associated with an increased risk of preterm labor?

• A. Periodontal infection
• B. Regular exercise
• C. Adequate sleep
• D. Balanced diet

Answer: (A)

Periodontal infection can contribute to preterm labor through systemic inflammation. Gum disease releases inflammatory mediators such as IL-6, TNF-alpha, and prostaglandins that enter the maternal circulation and stimulate uterine contractions and cervical ripening, increasing the risk of preterm birth. In contrast, regular exercise, adequate sleep, and a balanced diet support pregnancy health and are not associated with increased risk. Therefore, periodontal infection is the factor linked to higher risk of preterm labor.
