Edentulism is considered the ultimate sign of oral health disease burden. It is a common and frequent clinical disease, mostly seen in the elderly, which has been reported to be closely associated with many diseases. While physical activity is known to benefit many chronic diseases, the relationship between the volume of physical activity and edentulism remains unclear.
The CHARLS provided the data for this study. A total of 6,480 participants were enrolled in this study, of whom 46.02% were male and 53.98% were female. The edentulism was defined according to self-report and physical activity volume can be represented by metabolic equivalents. Multiple logistic regression, smooth curve fitting, threshold effects analysis, and Cox regression models were used to explore the relationship between physical activity volume and edentulism.
In the fully adjusted model, physically active participants had a 24% lower risk of edentulism compared to those who were physically inactive. Then, we subdivided participants with adequate physical activity into four levels: 600 ≤ PAV < 1200; 1200 ≤ PAV < 1800; 1800 ≤ PAV < 3000; and PAV ≥ 3000. We found that the risk of developing edentulism was lowest and statistically significant at the level of 1,800-3,000 MET-minutes/week physical activity volume (OR = 0.41; 95% CI, 0.24-0.69, p < 0.001). A U-shaped relationship between physical activity volume and edentulism with an inflection point of 2514 (MET-minutes/week) was observed. The results of the longitudinal study also confirm the benefits of physical activity volume with edentulism, participants with adequate physical activity volume had a 21% lower risk of developing edentulism than participants with inadequate physical activity volume (HR = 0.79; 95% CI, 0.67-0.94, p = 0.008).
This study reveals a U-shaped relationship between physical activity volume and edentulism. Physical activity reduces the risk of developing edentulism in middle-aged and older populations, but it is important to control the appropriate volume of physical activity.
无牙颌被认为是口腔健康疾病负担的最终标志。它是一种常见且频繁的临床疾病，主要见于老年人，据报道与许多疾病密切相关。虽然身体活动有益于许多慢性疾病，但身体活动量与无牙颌之间的关系尚不清楚。
CHARLS 为本研究提供了数据。共有 6480 名参与者纳入本研究，其中男性占 46.02%，女性占 53.98%。无牙颌根据自我报告定义，身体活动量可以用代谢当量表示。采用多因素逻辑回归、平滑曲线拟合、阈效应分析和 Cox 回归模型探讨身体活动量与无牙颌的关系。
在完全调整的模型中，与不活跃的参与者相比，积极活动的参与者患无牙颌的风险降低了 24%。然后，我们将有足够身体活动的参与者细分为四个水平：600≤PAV<1200；1200≤PAV<1800；1800≤PAV<3000；和 PAV≥3000。我们发现，在每周 1800-3000 代谢当量分钟的身体活动量水平，发生无牙颌的风险最低且具有统计学意义（OR=0.41；95%CI，0.24-0.69，p<0.001）。观察到身体活动量与无牙颌之间存在 U 型关系，拐点为 2514（MET 分钟/周）。纵向研究的结果也证实了身体活动量对无牙颌的益处，与身体活动量不足的参与者相比，身体活动量充足的参与者发生无牙颌的风险降低了 21%（HR=0.79；95%CI，0.67-0.94，p=0.008）。
本研究揭示了身体活动量与无牙颌之间存在 U 型关系。身体活动可降低中年和老年人发生无牙颌的风险，但控制身体活动的适当量很重要。
