Abstract

Objectives

Previous research has shown that people with obesity are at a higher risk of tooth loss; however, it is unclear whether abdominal obesity (e.g., high waist circumference) is associated with tooth loss among individuals without obesity. This study aims to investigate the association between abdominal obesity and tooth loss among people who are not obese.

Material and Methods

Two cross-sectional surveys were used: the United States' National Health and Nutrition Examination Survey (NHANES) 1999–2012 (n = 19,436) and the Scottish Health Survey (SHeS) 2008–2014 (n = 4243). Tooth loss was measured by the number of remaining teeth: 20 and over, 1–19, and edentulous. Abdominal obesity was defined by categorizing waist circumference into three levels: normal, high, and very high. Ordinal logistic regression was used to model the association between tooth loss and abdominal obesity.

Results

For people living without obesity, abdominal obesity is associated with a higher prevalence of tooth loss, and the effect is different between women and men. For women, abdominal obesity increased the chance of tooth loss by 64% (odds ratio [OR]: 1.64, 95% confidence interval [CI]: 1.16–2.34) in the NHANES and 196% (OR: 2.96, 95% CI: 1.47–5.97) in the SHeS. For men, abdominal obesity increased the chance of tooth loss by 41% (OR: 1.41, 95% CI: 1.06–1.87) in the NHANES and 65% (OR: 1.65, 95% CI: 1.02–2.73) in the SHeS.

Conclusions

This study indicated that the prevalence of tooth loss is substantially higher in people with abdominal obesity, and this association is distinctively different between men and women. These findings suggest that those who are not obese but have abdominal obesity may be an important target population for oral health prevention strategies.

腹部肥胖但体重正常者牙齿脱落的发生率更高：来自美国和苏格兰人群的研究结果

目的以往的研究表明，肥胖者患牙齿脱落的风险较高；但腹部肥胖（如腰围过高）是否与非肥胖者的牙齿脱落有关，目前尚不清楚。本研究旨在调查腹型肥胖与非肥胖人群牙齿脱落之间的关系。材料和方法采用了两项横断面调查：1999-2012 年美国国家健康与营养调查（NHANES）（n = 19436）和 2008-2014 年苏格兰健康调查（SHeS）（n = 4243）。牙齿缺失按剩余牙齿数量进行测量：20颗及以上、1-19颗和无牙。腹部肥胖的定义是将腰围分为三个等级：正常、高和非常高。采用序数逻辑回归来模拟牙齿脱落与腹型肥胖之间的关系。结果对于没有肥胖症的人来说，腹型肥胖与较高的牙齿脱落率有关，而且男女之间的影响不同。在 NHANES 调查中，腹部肥胖使女性牙齿脱落的几率增加了 64%（几率比 [OR]：1.64，95% 置信区间 [CI]：1.16-2.34），在 SHeS 调查中增加了 196%（OR：2.96，95% 置信区间 [CI]：1.47-5.97）。就男性而言，在 NHANES 中，腹部肥胖会使牙齿脱落的几率增加 41%（OR：1.41，95% CI：1.06-1.87），而在 SHeS 中，腹部肥胖会使牙齿脱落的几率增加 65%（OR：1.65，95% CI：1.02-2.73）。结论本研究表明，腹型肥胖者的牙齿脱落率要高得多，而且这种关联在男性和女性之间存在明显差异。这些研究结果表明，腹部肥胖的非肥胖人群可能是口腔健康预防策略的重要目标人群。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
