Background:
Very few meta-analyses discussed risk factors for lateral epicondylitis (LE), and previous meta-analyses reached conflicting conclusions with each other on some specific risk factors.
Purpose:
To investigate the risk factors for LE through meta-analysis.
Study Design:
Meta-analysis.
Methods:
PubMed, Embase, and Web of Science databases were searched for relevant studies in January 2022. Raw data were extracted into a predefined worksheet, and quality analysis was conducted by the Quality in Prognosis Studies (QUIPS) tool. Pooled effect sizes and 95% confidence intervals were calculated. R package "meta" was used for statistical analysis.
Results:
22 studies were included in the meta-analysis. Female sex (odds ratio [OR]=1.33 and p-value<0.05), smoking history (OR=1.46 and p-value<0.001), manual labor (OR=2.39 and p-value<0.001), and hypercholesterolemia (OR=1.67 and p-value<0.05) were significant risk factors for LE.
Conclusions:
Female gender, smoking history, manual labor, and hypercholesterolemia could increase the risk of LE. According to an additional literature review, statin treatment for hypercholesterolemia is described as potentially related to the development of LE.
