Abstract
BACKGROUND: The present study determines the association of obesity, gender, age and occupation in patients with carpal tunnel syndrome (CTS) in a New Zealand population. METHODS: Analysis of questionnaires and clinical review of patients who had undergone surgical decompression of the median nerve in the carpal tunnel. RESULTS: The age and gender distribution of 655 hands (512 patients) that had undergone carpal tunnel release (CTR) were compared with the age and gender distribution of the New Zealand population. The results indicate that the 3-year-period prevalence of CTS in females is more than double that in males. Proportionally there were more patients over age 55 than in the general population. The findings also indicate that, proportionally, six times the number of females who worked in moderate manual work underwent CTR compared with the general female population and proportionally twice the number of males who worked in heavy office/clerical work underwent CTR compared with the general male population. It was also found that CTR patients are twice as likely to be overweight (body mass index [BMI] > 25) than the general population and female patients are twice as likely to be obese (BMI > 30) than the general population. CONCLUSIONS: Carpal tunnel syndrome is more than twice as common in females as it is in males, and patients aged more than 55 years are more likely to suffer from CTS. Females with CTS are more likely to work in moderate manual work and males with CTS are more likely to work in heavy office/clerical work. Obesity and CTS are related statistically.
