Effect of Baduanjin exercises on elevated blood lipid levels of middle-aged and elderly individuals: protocol for a systematic review and meta-analysis of randomised controlled trials

Objective

To assess the safety and effect on elevated blood lipid levels of Baduanjin exercises in middle-aged and elderly individuals.

Methods

A systematic literature search for articles up to March 2017 will be conducted using seven databases: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data. Inclusion criteria are randomised controlled trials of Baduanjin exercises that examine blood lipid levels in middle-aged and elderly individuals. The primary outcome measures will be total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Stata V.13.0 software will be used for data synthesis, sensitivity analysis, metaregression, subgroup analysis and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias and Begg and Egger tests will be used to assess funnel plot symmetries. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence.

Ethics and dissemination

This systematic review will be submitted to a peer-reviewed journal. Our findings will provide information about the safety of Baduanjin exercises for middle-aged and elderly individuals and their effect on elevated blood lipid levels.
