OBJECTIVE: To assess the associations between carpal tunnel syndrome (CTS)
severity and selected anthropometric and obesity indexes.
DESIGN: We performed a
case-control study. Clinical and electrophysiological severity of CTS was
classified as mild, moderate, or severe based on validated scales. Body and hand
anthropometric characteristics were measured at the time of the electrodiagnostic
study. We estimated the relative risk ratios (RRRs) of CTS severity by fitting
multinomial logistic regression models adjusted by age and sex. In addition, we
fitted multivariable models, including age, sex, wrist ratio, hand ratio, body
mass index (BMI), and waist/stature ratio. SETTING: Electromyography
laboratories. PARTICIPANTS: Consecutive patients (N=1087), those with CTS (n=340)
and those without CTS (n=747), were enrolled. INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: Associations between CTS severity and selected anthropometric
and obesity indexes. RESULTS: We observed associations between many
anthropometric indexes and CTS severity. Among obesity indexes, the waist/stature
ratio, and among hand anthropometric indexes, the wrist/palm ratio, showed the
highest RRRs for the clinical and electrophysiological severity scales. The RRRs
of severe CTS (adjusted for age and sex) for the wrist/palm ratio were 3.5 for
the clinical scale and 2.4 for the electrophysiological scale. The RRRs of severe
CTS for the waist/stature ratio were 2.3 for the clinical scale and 2.0 for the
electrophysiological scale. In the multivariable models, both BMI and the
waist/stature ratio were associated with the outcomes. CONCLUSIONS: Different
configurations of the body and, in particular, the hand and wrist system may
influence the occurrence and severity of CTS. Multiple obesity indexes, possibly
including the waist/stature ratio, should be considered when investigating the
association between body composition and CTS. Future studies should determine
whether in obese subjects with CTS the weight and waist circumference loss
produces an improvement in CTS symptoms and recovery of distal conduction
velocity of the median nerve.
