Factors associated with post-partum smoking relapse in Taiwan: A trial of Smoker's helpline

Many women quit smoking during pregnancy resume in postpartum period and difficult to prevent. No studies had focused on their psychosocial response in Taiwan. We analyzed data from a trial of Taiwan Smoker's Helpline (TSH) to determine factors associated with smoking relapse after delivery.

A prospective cohort was conducted at Taipei City Hospital during Sep. 2014 and Nov. 2015 period. We collected data by self-developed questionnaire combining theory of planned behavior (TPB), Fagerstrom test for nicotine dependence (FTND) and Edinburgh Postnatal Depression Scale (EPDS) from 68 women immediately after delivery, 2 months later and followed up until 6 months. Multivariable logistic models for relapse of smoking at the end of 3rd month and 6th month were created.

At 6th month, 42.6% participants relapsed with odds lower among first parity (OR = 0.04, 95% CI = <0.01-0.54, p = 0.015), having quitting experience in past (OR = 0.09, 95% CI = 0.01-0.84, p = 0.019) and higher perceived behavior control (PBC) (OR = 0.99, 95% CI = 0.98-1.00, p = 0.035), but greater for those with longer smoking duration in past (OR = 1.29, 95% CI = 1.04-1.58, p = 0.018).

Protective and precipitating factors to post-partum's smoking relapse were identified in our study.
