The purpose of this population‐based, case‐control study was to examine the association between maternal smoking and clubfoot. ## METHODS: Data from the North Carolina Birth Defects Monitoring Program matched to North Carolina birth certificates and health services data were used in the analysis of 443 cases of clubfoot and 4,492 randomly sampled controls for the years 1999–2003. Smoking data were ascertained from the birth certificates, and the reliability of the data was assessed by comparing them with reported smoking from the North Carolina Pregnancy Risk Assessment Monitoring System. Multiple logistic regression was used to calculate crude and adjusted ORs and 95% CIs for smoking and clubfoot. ## RESULTS: The crude OR for maternal smoking during pregnancy and clubfoot was 1.49 (95% CI: 1.15, 1.92). Controlling for maternal age, race/ethnicity,
