This study suggests that spousal smoking status influences
one’sown propensity to quit smoking.Compared with subjects
whose spouses had never smoked, subjects whose spouses
were current smokers had significantly lower chances of quitting.
This was true for both men and women and remained
unchanged after controlling for physiological or social factors
that may influence smoking status. This effect was not
symmetrical between sexes; having a spouse who smoked
had a stronger adverse impact on men’s ability to quit than
on women’s.
