A body Shape index (ABSI), defined as waist circumference (WC)/(body mass index (BMI) × height), is unique in that the ABSI is positively associated with visceral obesity and is independent of BMI. The ABSI has also been shown to be positively and linearly correlated with the amount of visceral adiposity in the general population and with all-cause and cardiovascular disease (CVD). However, it is uncertain whether ABSI is associated with periodontitis in hypertensive patients. A cross-sectional study of 2,482 hypertensive patients (mean age 65.2 ± 9.1 years) was conducted using the ABSI Z score, periodontitis as a dichotomous variable, the ABSI Z score as a continuous variable, and multiple covariates such as age, gender, and race. The data were analyzed using descriptive statistics, multiple regression model, subgroup analysis with EmpowerStats (version 4.2), and curve transformation plots were generated. In multiple regression model analysis, ABSI Z score showed a significant positive association with periodontitis in the hypertensive population in all three models. When ABSI Z score was divided into low, moderate, and high three groups, we observed that those with the highest ABSI Z score had a 20% increased risk of periodontitis among people with hypertension (OR 1.2; 95% CI 1.0, 1.5; p = 0.046). We used smooth curve fitting to confirm the results and found that these results were still supported, and additional subgroup analyses showed that the positive association between ABSI Z score and periodontitis in hypertensive population was stable and consistent in the general population. The present cross-sectional investigation showed a positive association between ABSI Z score and periodontitis in a hypertensive population.
体脂指数（ABSI）定义为腰围（WC）/（体重指数（BMI）×身高），其独特之处在于与内脏肥胖呈正相关，且与 BMI 无关。ABSI 也与普通人群的内脏脂肪量以及全因和心血管疾病（CVD）呈正相关和线性相关。然而，ABSI 与高血压患者的牙周炎之间是否存在关联尚不确定。使用 ABSI Z 评分、牙周炎作为二分类变量、ABSI Z 评分作为连续变量以及年龄、性别和种族等多个协变量，对 2482 例高血压患者（平均年龄 65.2±9.1 岁）进行了横断面研究。采用描述性统计、多元回归模型、EmpowerStats（版本 4.2）亚组分析和曲线转换图进行数据分析。在多元回归模型分析中，ABSI Z 评分在三种模型中均与高血压人群的牙周炎呈显著正相关。当 ABSI Z 评分分为低、中、高三组时，我们观察到，ABSI Z 评分最高的人群中，高血压患者的牙周炎风险增加 20%（OR 1.2；95%CI 1.0，1.5；p=0.046）。我们使用平滑曲线拟合来确认结果，发现这些结果仍然得到支持，进一步的亚组分析表明，ABSI Z 评分与高血压人群牙周炎之间的正相关关系在普通人群中是稳定一致的。本横断面研究显示，ABSI Z 评分与高血压人群的牙周炎之间存在正相关关系。
