Obesity and periodontitis are public health issues in Australia. This study aimed to determine the association between overweight/obesity and periodontitis in Australian adults.
The cross-sectional National Survey of Adult Oral Health 2004-2006 data were analysed. Body mass index was calculated, and a self-reported questionnaire was used to measure the estimated daily intake of added sugar. The mean number of sites with probing depth (PD) ≥ 4 mm and clinical attachment loss (CAL) ≥ 4 mm and presence of periodontitis were used as outcome measures. CDC/AAP periodontitis case definition was adopted. Bivariate analyses and multiple variable regression models were constructed.
The study sample was 4,170 participants. The proportion of people that were overweight/obese was 51.9% [95% confidence interval (CI): 48.1%, 54.1%]. Overall 21.3% (95% CI: 19.3%, 23.5%) people experienced periodontitis. The mean number of sites with PD ≥ 4 mm and CAL ≥ 4 mm were recorded as 0.7 (95% CI: 0.5, 0.9) and 2.4 (95% CI: 2.1, 2.6), respectively. Multiple variable analysis suggested that periodontal parameters [sites with PD ≥ 4 mm (0.13, 95% CI: -0.86, 0.35) and sites with CAL ≥ 4 mm (0.11, 95% CI: -0.58, 0.35) and presence of periodontitis (1.23, 95% CI: 0.96, 1.57)] were not associated with overweight/obesity when controlled for putative confounders.
A positive association was found between overweight/obesity and periodontitis (PD and CAL). However, the statistical significance disappeared in the multiple variable regression analysis, where age, sex, smoking and dental visiting behaviour were found to be key determinants of periodontitis.
肥胖和牙周炎是澳大利亚的公共卫生问题。本研究旨在确定超重/肥胖与澳大利亚成年人牙周炎之间的关系。
对 2004-2006 年全国成人口腔健康横断面调查数据进行分析。计算体重指数，并使用自我报告问卷测量估计的每日添加糖摄入量。使用探诊深度（PD）≥4mm 和临床附着丧失（CAL）≥4mm 的平均位点数量以及牙周炎的存在作为结果测量指标。采用疾病控制与预防中心/美国牙周病学会牙周炎病例定义。进行了双变量分析和多变量回归模型构建。
研究样本为 4170 名参与者。超重/肥胖者的比例为 51.9%（95%置信区间：48.1%，54.1%）。总体而言，21.3%（95%置信区间：19.3%，23.5%）的人患有牙周炎。记录的 PD≥4mm 和 CAL≥4mm 的平均位点数分别为 0.7（95%置信区间：0.5，0.9）和 2.4（95%置信区间：2.1，2.6）。多变量分析表明，牙周参数[PD≥4mm 的位点数（0.13，95%置信区间：-0.86，0.35）和 CAL≥4mm 的位点数（0.11，95%置信区间：-0.58，0.35）和牙周炎的存在（1.23，95%置信区间：0.96，1.57）]在控制了可能的混杂因素后，与超重/肥胖无关。
超重/肥胖与牙周炎（PD 和 CAL）之间存在正相关关系。然而，在多变量回归分析中，这种统计学意义消失了，年龄、性别、吸烟和看牙行为被发现是牙周炎的关键决定因素。
