To ascertain the comparative effectiveness of weight-loss strategies for osteoarthritis (OA) to develop rational treatment algorithms aimed at improving OA-related symptoms in overweight/obese individuals. Medline, Embase, CINAHL, Scopus, and Web of Science were searched from inception to June 2023 for observational studies and randomized trials. Network meta-analyses were performed using a frequentist approach. Effect sizes for pain and function were computed as standardized mean differences, while change in body weight was computed as mean differences. 13 RCTs on knee OA (KOA) (2800 participants) with 7 interventions: diet (D); exercise (E); diet and exercise (DE); pharmacological (L); psychological (P); psychological, diet, and exercise (PDE); and Mediterranean diets (M) were networked. For weight change (kg), all interventions significantly outperformed control comparators, with effect sizes ranging from −11.2 (95% CI, −16.0, −6.5 kg) for the most effective approach (PDE) to −4.7 (95% CI, −6.7, −2.7 kg) for the least effective approach (DE). In terms of pain (0–20 scale), only DE outperformed control comparators (−2.2, 95% CI: −4.1, −0.21), whereas PDE was not superior to control comparators (−3.9, 95% CI: −8.4, 0.5) in improving the pain. Regardless of the chosen intervention, prediction intervals from meta-regression analysis indicate that significant pain relief may be anticipated when patients achieve at least a weight reduction of 7%. PDE and DE interventions may offer the most effective approach for weight loss, potentially leading to improvements in pain and physical function among overweight/obese individuals with KOA if they achieve more than 7% weight loss.

超重和肥胖成人膝骨关节炎减肥干预的比较:随机试验的系统评价和网络荟萃分析



确定骨关节炎 (OA) 减肥策略的比较有效性,以开发合理的治疗算法,旨在改善超重/肥胖个体的 OA 相关症状。检索了从建库到 2023 年 6 月的 Medline、Embase、CINAHL、Scopus 和 Web of Science 的观察性研究和随机试验。使用频率主义方法进行网状meta分析。疼痛和功能的效应大小计算为标准化平均差,而体重变化计算为平均差。13 项关于膝关节 OA (KOA) 的 RCT(2800 名参与者)和 7 项干预措施:饮食 (D);锻炼 (E);饮食和运动 (DE);药理学 (L);心理 (P);心理、饮食和运动 (PDE);和地中海饮食 (M) 是联网的。对于体重变化 (kg),所有干预措施均显著优于对照对照,效应量范围从最有效方法 (PDE) 的 -11.2 (95% CI, -16.0, -6.5 kg) 到最无效方法 (DE) 的 -4.7 (95% CI, -6.7, -2.7 kg) 不等。在疼痛方面(0-20 分制),只有 DE 优于对照组 (-2.2, 95% CI: -4.1, -0.21),而 PDE 在改善疼痛方面并不优于对照组 (-3.9, 95% CI: -8.4, 0.5)。无论选择哪种干预措施,meta 回归分析的预测区间都表明,当患者体重至少减轻 7% 时,可以预期疼痛会显着缓解。PDE 和 DE 干预可能提供最有效的减肥方法,如果超重/肥胖的 KOA 个体的体重减轻超过 7%,则可能会改善他们的疼痛和身体机能。
