Abstract

Background

This study aimed to assess the longitudinal association between dynapenic abdominal obesity and new-onset arthritis among the middle-aged and older Chinese population.

Methods

We included 6863 participants from the 2011 and 2015 waves of the China Health and Retirement Longitudinal Study (CHARLS). Dynapenia was defined as handgrip strength < 28 kg for males, and < 18 kg for females. Abdominal obesity was defined as a waist circumference ≥ 90 cm for males and ≥ 85 cm for females. Based on the definitions, all participants were divided into four groups: no dynapenia and no abdominal obesity (ND/NAO), abdominal obesity alone (ND/AO), dynapenia alone (D/NAO), and dynapenia and abdominal obesity (D/AO). The association between dynapenic abdominal obesity and new-onset arthritis was assessed by sex using the Poisson regression models.

Results

After a four-year follow-up, 1272 (18.53%) participants reported new-onset arthritis. Those in the D/AO group had a significantly increased risk of new-onset arthritis compared to those in the ND/NAO group (adjusted relative risk (RR): 1.34, 95% confidence interval (CI): 1.01–1.77). In females, the ND/AO (RR: 1.21, 95% CI: 1.03–1.43) and D/AO (RR: 1.39, 95% CI: 1.01–1.93) groups were associated with a higher risk of arthritis. This significant association was not observed in males.

Conclusions

Our results indicated that the combined effect of dynapenia and abdominal obesity significantly increased the risk of new-onset arthritis in females, but this association was not observed in males.

中国中老年人腹部动态肥胖与关节炎的关系:一项纵向研究。
研究背景本研究旨在评估中国中老年人群中动态腹型肥胖与新发关节炎之间的纵向联系:我们纳入了中国健康与退休纵向研究(CHARLS)2011 年和 2015 年的 6863 名参与者。结果:经过四年的随访,1272 名中国中老年人患上了动力性关节炎:经过四年的随访,1272 名参与者(18.53%)报告了新发关节炎。与 ND/NAO 组相比,D/AO 组患者新发关节炎的风险明显增加(调整后相对风险 (RR):1.34,95% 置信区间):1.34,95% 置信区间 (CI):1.01-1.77)。在女性中,ND/AO 组(RR:1.21,95% 置信区间:1.03-1.43)和 D/AO 组(RR:1.39,95% 置信区间:1.01-1.93)患关节炎的风险较高。结论:我们的研究结果表明,动态关节炎和腹型肥胖的共同作用会显著增加女性罹患新发关节炎的风险,但在男性中却没有观察到这种关联。
