Abstract

Background: It is unclear whether hand grip strength can predict the risk of future tooth loss. This study aims to explore the association between hand grip strength levels and lost all teeth in the middle-aged and elderly population in China through a nationwide cohort study.

Method: Based on the China Health and Retirement Longitudinal Study (CHARLS), 8360 participants aged 45 years or older (58.60 ± 8.04 years) were included, who participated in two rounds of surveys in 2015 and 2018. Participants were divided into four groups based on the hand grip strength (standardised by body weight) quartile of the baseline survey. A multiple logistic regression model was used to analyse the association between hand grip strength and lost all teeth. Restricted cubic spline (RCS) was used to analyse the dose-response relationship between hand grip strength and lost all teeth.

Result: During the follow-up period, 488 (5.80%) study subjects were found to have lost all teeth. In comparison with the study subjects who had incomplete tooth loss, those with complete tooth loss were older, with a higher body mass index (BMI) and a larger waist circumference. Multivariate analysis revealed a significant negative correlation between grip strength level and the risk of complete tooth loss. Further subgroup analysis indicated that the association between standardised hand grip strength and the risk of losing all teeth was strong in both male and normal C-reactive protein (CRP) levels subgroups. There was no non-linear dose-response relationship between hand grip strength level and the risk of complete tooth loss (p non-linear > 0.05).

Conclusion: Our findings reveal a negative correlation between standardised grip strength and complete tooth loss, with higher levels of standardised grip strength being associated with a lower risk of complete tooth loss.

中老年人标准化握力与全牙脱落之间的关系：一项全国性队列研究。

背景：目前尚不清楚握力是否可以预测未来牙齿脱落的风险。本研究旨在通过一项全国性的队列研究，探讨中国中老年人群握力水平与全牙脱落之间的关系。方法：基于中国健康与退休纵向研究（CHARLS），纳入8360名年龄在45岁及以上（58.60±8.04岁）的参与者，于2015年和2018年参加两轮调查。参与者根据基线调查的握力（按体重标准化）四分位数分为四组。采用多元逻辑回归模型分析了手握力与全牙脱落之间的关系。采用受限三次样条（RCS）分析了手握力与全牙脱落的剂量-响应关系。结果：随访期间，488例（5.80%）患者全部牙齿脱落。与牙齿不完全脱落的研究对象相比，牙齿完全脱落的研究对象年龄更大，体重指数（BMI）更高，腰围也更粗。多因素分析显示，握力水平与全牙脱落风险呈显著负相关。进一步的亚组分析表明，在男性和正常c反应蛋白（CRP）水平的亚组中，标准化握力与牙齿脱落风险之间的关联都很强。握力水平与全牙脱落风险之间不存在非线性剂量-反应关系（p < 0.05）。结论：我们的研究结果揭示了标准化握力与全牙脱落之间的负相关关系，较高水平的标准化握力与较低的全牙脱落风险相关。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
