Factors associated with carpal tunnel syndrome incidence in culinary workers in Kota Bandar Lampung

Carpal tunnel syndrome occurs due to median nerve compression in the wrist and causes feeling of tingling, numbness and weakness in the affected hand. A repetitive movement of hand flexion and extension in a long period of time by culinary workers can cause this syndrome to develop. The prevalence of CTS in workers are high and still cause problem for workers and companies due to its bad impacts to decrease productivity and working capacity as well as increasing health care cost. This study aimed to determine risk factors related to the incidence of CTS. This research was an observational analytical study design with cross sectional approach (level of significance 5%) conducted among 75 culinary workers using accidental sampling technique. The data was analyzed by Chi Square for bivariate analysis and logistic regression predictive model for multivariate analysis. The results showed that most of subjects were diagnosed with CTS in 73.3% subjects and aged ≥40 years old in 46.7% subjects. Subjects had normal BMI (53.3%), ≥4 years of work period (53.3%), ≥8 hours of daily work duration (90.7%), high risk level of wrist working posture (58.7%). There was a significant relationship between age (p-value=0.045), BMI (p=0,020), work period (p = 0,029), daily duration of work (p = 0.013), to CTS. The result of multivariate analysis showed work period (OR = 6.528) was the most influencing factors to CTS.
