Maternal periodontitis as a risk factor for prematurity
Pediatrics International, 04/30/2012
Piscoya MDBV et al. – Periodontitis is strongly associated with prematurity, indicating necessity for regular periodontal investigation and treatment during pregnancy.Methods
- The authors carried out a case–control study including 718 puerperae who experienced a spontaneous delivery: 360 cases (premature) and 358 controls (full-term).
- Sociodemographic, obstetric, prenatal, perinatal and periodontal data were obtained within 48 h after delivery.
- Periodontitis was defined as probing depth >4 mm and attachment loss >3 mm at same site, for >4 teeth.
- Periodontitis was associated with prematurity (odds ratio 6.95; confidence interval 3.69–13.09).
- Prematurity was associated with maternal age < 20 years, family income < one minimum salary, maternal schooling < 8 years, premature birth history, premature membrane rupture, ruptured membranes > 24 h, smoking, urinary tract infection, leukorrhea, pre-eclampsia, prenatal consultations < 3 and precarious housing.
- After multivariate confounder adjustments, periodontitis remained independently associated with prematurity (odds ratio 6.05; confidence interval 3.01–12.16).
