Aim The aim of this study was to investigate if pregnant women with both obesity and periodontitis are more likely to experience preterm birth ( PTB ) in women with pre‐eclampsia ( PE ) than pregnant women with only obesity or only periodontitis. Materials and Methods The study examined a total of 328 pregnant women at 21–24 weeks of gestation. Overweight and obesity was defined based on criteria proposed by the WHO Expert Consultation. Periodontal conditions were assessed by measuring periodontal clinical attachment loss. PTB was defined as delivery at <37 weeks, and PE was defined as blood pressure higher than 140/90 mmHg on two separate occasions with at least 1+ proteinuria on a random urine screen after the 20th week of pregnancy. Results After adjusting for other important cofactors, pregnant women with periodontitis were 5.56 times [95% confidence interval ( CI ) = 1.22–25.39] more likely to have PTB with PE than women without periodontitis. The association was much stronger (odds ratio = 15.94, 95% CI = 3.31–76.71) in women with both obesity and periodontitis. Conclusions Our results of this study indicate that pregnant women with both pre‐pregnancy obesity and periodontitis are significantly more likely to have PTB with PE than pregnant women with only periodontitis.
