摘要

目的：我们旨在进行一项系统综述和荟萃分析，以评估植物性饮食（PBD）对慢性肾脏疾病（CKD）的影响。方法：系统检索PubMed和Embase，从成立到2023年8月，评估采用PBD与CKD发病率、进展和死亡率之间的关系。使用随机效应模型估计优势比（ORs）和95%置信区间（ci）。该荟萃分析已在PROSPERO中预先登记。结果：共纳入121,927名参与者，年龄在18 - 74岁之间，加权平均随访11.2年。采用PBD与CKD发生风险显著降低相关OR=0.75, 95% CI(0.65, 0.86)，结论：采用PBD与CKD发病率降低26%显著相关。较高的PBD摄入量与较低的CKD发病率和较慢的CKD进展呈剂量依赖关系。与健康PBD相比，不健康PBD可能不具有肾脏保护作用。

Plant-Based Diet and Chronic Kidney Disease: A Systematic Review and Meta-Analysis

Objective

We aimed to perform a systematic review and meta-analyses to evaluate the impact of plant-based diet (PBD) on chronic kidney disease (CKD).

Methods

A systematic search of PubMed and Embase was conducted from inception to August 2023 to evaluate the association between adopting a PBD and the incidence, progression, and mortality of CKD. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using a random effects model. This meta-analysis was preregistered in the PROSPERO.

Results

A total of 121,927 participants were included, aged between 18 and 74 years, and were followed up for a weighted average of 11.2 years. Adopting PBD is associated with a significantly reduced risk of developing CKD OR = 0.75, 95% CI (0.65-0.86), P < .0001] across 93,857 participants. Similar results were observed in subgroup analyses that examined higher quintiles/quartiles (Q2-Q5) and tertiles (T2-T3) of PBD versus Q1/T1, with overall effect measures of 0.92 (95% CI; 0.86-0.98) and 0.88 (95% CI; 0.82-0.93), respectively. When adjusting for CKD-related comorbidities in patients following PBD (adjusted models M1, M2, and M3), significant findings were also observed, with an overall OR of 0.86 (95% CI; 0.79-0.93).

Conclusion

Adopting PBD was significantly associated with 26% lower incidences of CKD. Higher intake of PBD showed a dose-dependent relationship with lower risk of CKD incidence and slower CKD progression. Unhealthy PBD may not confer renal protective effects compared to healthy PBD.
