BackgroundExcess weight (EW), especially in women of childbearing age, those who are pregnant, as well as postpartum, is a problem worldwide. Fat accumulation deregulates the inflammatory response, contributing to the development of health problems, such as periodontitis. This study investigated the association between EW and periodontitis during pregnancy.MethodsA cross‐sectional, multicenter study involved 1745 postpartum women in Brazil. Socioeconomic‐demographic data, gestational history, lifestyle behavior, and general and oral health conditions were obtained. Pre‐pregnancy body mass index (BMI) was collected from medical records with EW being the exposure. Both tooth loss and clinical attachment level (CAL) were evaluated, and the presence of periodontitis was the outcome. Logistic regression, odds ratio (OR) and 95% confidence interval (95% CI), and quantile regression, beta coefficient and 95% CI, estimated the association between EW (BMI) and periodontitis and its combined effect with tooth loss ≥3, as dichotomous and continuous variables (CAL and tooth loss), with 5% significance level.ResultsThe EW was 27.7% prevalent and periodontitis was 11.7%. There was a positive association between EW and periodontitis: ORadjusted:1.39; 95% CI:1.01;1.92 and between EW and periodontitis combined with tooth loss ≥3: ORadjusted:1.73; 95% CI:1.36;2.20. The adjusted association between EW and periodontitis as continuous variables was also positive, showing that for each unit of increased BMI, there was an elevation in the mean CAL (p = 0.04) and tooth loss (p < 0.01), with statistical significance.ConclusionsThere was a moderate association between EW and periodontitis during pregnancy, with an even greater association of pregnant women with EW presenting periodontitis combined with tooth loss.

孕妇体重过重会增加诊断牙周炎合并牙齿脱落的机会


背景超重（EW），特别是育龄妇女、怀孕妇女以及产后妇女，是一个世界性的问题。脂肪堆积会放松炎症反应，导致牙周炎等健康问题的发生。本研究调查了怀孕期间 EW 与牙周炎之间的关联。方法一项横断面、多中心研究涉及巴西 1745 名产后妇女。获得了社会经济人口统计数据、妊娠史、生活方式行为以及一般和口腔健康状况。孕前体重指数（BMI）是从医疗记录中收集的，EW 是暴露量。对牙齿脱落和临床附着水平（CAL）进行了评估，结果是牙周炎的存在。 Logistic 回归、比值比 (OR) 和 95% 置信区间 (95% CI) 以及分位数回归、β 系数和 95% CI 估计了 EW (BMI) 与牙周炎之间的关联及其与牙齿脱落≥3 的综合效应，作为二分变量和连续变量（CAL 和牙齿脱落），显着性水平为 5%。结果 EW 患病率为 27.7%，牙周炎患病率为 11.7%。 EW 和牙周炎之间存在正相关：OR调整过的：1.39； 95% CI:1.01;1.92 EW 与牙周炎合并牙齿脱落≥3 之间：OR调整过的：1.73； 95% CI：1.36；2.20。作为连续变量，EW 和牙周炎之间的调整相关性也呈正相关，表明 BMI 每增加一个单位，平均 CAL 就会升高（ p = 0.04) 和牙齿缺失 ( p < 0.01），具有统计学意义。结论 妊娠期间 EW 与牙周炎之间存在中度关联，而患有 EW 的孕妇出现牙周炎并伴有牙齿脱落的关联性更大。
