Abstract
BACKGROUND
Dupuytren's disease is a common complex disease caused by genetic and nongenetic factors. The role of many nongenetic risk factors is still unclear and debatable. This study aimed to systematically review the association between Dupuytren's disease and nongenetic risk factors.
METHODS
A search strategy was developed based on the Population, Exposure, Comparison, Outcomes and Study framework. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant literature search was conducted in MEDLINE, Embase, Scopus, Web of Science, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials from inception to November of 2018. Title and abstract and then full-text screening against eligibility criteria was performed independently by two reviewers, and consensus was achieved by a third reviewer. The Effective Public Health Practice Project and the Oxford Centre for Evidence Based Medicine tools were used to assess study quality and to evaluate the level of evidence of included studies, respectively.
RESULTS
Reviewers identified 4434 studies, of which 54 were included in the analysis. There was strong evidence for the association between Dupuytren's disease and advanced age, male sex, family history of Dupuytren's disease, and diabetes mellitus. Furthermore, heavy alcohol drinking, cigarette smoking, and manual work exposure showed a significant dose-response relationship. The quality of the included studies was mainly low or moderate, and most studies were level 3 or 4 on the Oxford Centre for Evidence Based Medicine scale.
CONCLUSIONS
The study results show a strong association between Dupuytren's disease and advanced age, male sex, family history of Dupuytren's disease, diabetes mellitus, heavy alcohol drinking, cigarette smoking, and manual work exposure. Further studies are required to explain the causal relationship of these associations.
