Design A total of 156 patients, including 64 women with normal birth outcome (NB) and 92 women with preterm/low birth weight outcome (PLBW) were included in this case-control study. Within 24 h after labor, maternal demographic characteristics and clinical periodontal parameters were recorded. The distribution and genotype frequencies of IL-1 were analyzed with polymerase chain reaction-restriction fragment length polymorphism assay. Statistical analyses were carried out for clinical periodontal parameters, genotype frequencies, and to identify explanatory variables for PLBW. Results PLBW was associated with maternal age (p < 0.05), irregular prenatal care (p < 0.001), previous PLBW (p < 0.05), and antibiotic use during pregnancy (p < 0.05). Measurements of probing depth and clinical attachment level (CAL) were significantly higher in the PLBW group than in the NB group (p < 0.001). PLBW was associated with IL-1RN allele 2 (p < 0.001). Moreover, stepwise logistic regression analysis showed that CAL (OR 1.39, 95% CI: 1.04-1.85) and IL-1RN polymorphism (OR 7.92, 95% CI: 2.76-22.79), previous PLBW (OR 5.01, 95% CI: 1.08-23.17), age (OR 1.22, 95% CI: 1.04-1.44) were predictors found to increase the risk of PLBW (p < 0.05). There was a negative association between PLBW and regular prenatal care, total number of births, use an antibiotic during pregnancy period (p < 0.05). Conclusion Our study showed that, IL-1RN allele 2, periodontal disease characterized with clinical attachment loss, previous PLBW and age could be an important risk factors for PLBW.
