Prevalence and Associated Factors of Carpal Tunnel Syndrome Among Diabetic Patients in Arba Minch General Hospital, South West Ethiopia, 2021

Abstract

Purpose of the Study

This study aimed to assess the prevalence of carpal tunnel syndrome and associated factors among diabetic patients in Arba Minch General Hospital, Southwest Ethiopia. Carpal tunnel syndrome (CTS) is the second most common cause of absence from work which causes functional loss of the hands and leads to disability. However, it is understudied among diabetic patients in Ethiopia.

Patients and Materials

An institution-based cross-sectional study was conducted from May 1 to October 1, 2021. Systematic random sampling method was used to select 353 study participants. CTS-6 Evaluation tool was applied to assess carpal tunnel syndrome. The data was coded and entered into Epi-Data version 3.1 statistical packages and exported to SPSS version 25 for analysis. Binary logistic regression model was applied to assess the association between outcome variable and independent variables. Odds ratio (OR) with 95% CI and p-values <0.05 were used to identify significantly associated factors with an outcome variable.

Results

The study was conducted among 353 diabetic patients. The cumulative prevalence of carpal tunnel syndrome among diabetes was 3.1%. CTS was statistically significantly associated with high body mass index; AOR=0.34 (0.12, 0.97, 95% CI) (p=0.04. Majority of participants 322 (91.2%) had type 2 DM. Mean fasting blood sugar level ± standard error of study participants was 157.52 ± 1.91 mg/dl.

Conclusion

The prevalence of carpal tunnel syndrome was relatively low. High body mass index (BMI) was significantly but negatively associated with carpal tunnel syndrome compared to diabetic patients with normal BMI. Diabetic patients with normal BMI should be screened for CTS for early management of the disease and prevention of further complications. Further investigations are recommended.
