Background:
Our aim was to determine whether maternal smoking and offspring's own smoking affect the offspring's risk for carpal tunnel syndrome (CTS).
Method:
The study sample consisted of the Northern Finland Birth Cohort 1966 (N = 8703). Information on maternal smoking was collected from the participants' mothers. At 31 years, information on smoking, body mass index, socioeconomic status, and long-term illnesses were collected, combined with data of CTS diagnoses from the Care Register for Health Care (1997-2016).
Results:
Maternal smoking was not associated with increased risk of CTS in offspring. Before the age of 31 years, smoking ≤10 pack years (hazard ratio [HR] = 1.54, 95% confidence interval [CI] = 1.11-2.15) and >10 pack years (HR = 1.90; 95% CI = 1.20-3.01) among women, and >10 pack years (HR = 1.89; 95% CI = 1.14-3.12) among men was associated with CTS compared with nonsmokers.
Conclusions:
In this birth cohort, offsprings' own smoking was associated with CTS; however, maternal smoking was not.
