Association Between Cardiovascular Risk Factors and Carpal Tunnel Syndrome in Pooled Occupational Cohorts.

Area of Science:

• Occupational Health
• Neurology
• Cardiology

Background:

• Carpal tunnel syndrome (CTS) is a common condition affecting the hand and wrist.
• Cardiovascular disease (CVD) risk factors are well-established but their association with CTS is not fully understood.

Purpose of the Study:

• To investigate if cardiovascular disease risk factors are also risk factors for carpal tunnel syndrome.
• To determine the association between CVD risk scores and CTS prevalence.

Main Methods:

• Pooled analysis of baseline data from two large prospective cohort studies (n=1824).
• Assessed relationships between a modified Framingham Heart Study CVD risk score and CTS/abnormal nerve conduction study prevalence.
• Controlled for job exposures, personal, and psychosocial confounders; calculated odds ratios and 95% confidence intervals.

Main Results:

• A strong relationship was observed between CVD risk score and both CTS and abnormal nerve conduction study, even after adjusting for confounders.
• Odds ratios reached as high as 4.16 for CTS and 7.35 for abnormal nerve conduction study.
• Dose-response relationships were evident, indicating increased risk with higher CVD scores.

Conclusions:

• Strong association between CVD risk scores and CTS/abnormal nerve conduction study in a workplace population, persisting after confounder control.
• Suggests a potentially modifiable disease mechanism linking cardiovascular health to carpal tunnel syndrome.
• Highlights the importance of considering systemic health factors in CTS etiology.
