At the end of the programme, 64% of patients and 75% of partners were abstinent -- compared to none and 55% at the start, respectively. The odds of quitting smoking at 16 weeks were significantly higher (5.83-fold) in couples who tried to quit together compared to patients who attempted it alone. "Previous research has shown that ex-smokers can also positively influence their spouse's attempts to quit, but in this study the effect was not statistically significant," said Ms Lampridou. "As for non-smoking partners, there is a strong risk that they will adopt their spouse's habit." Ms Lampridou noted that research is needed to confirm the findings in smokers who are otherwise healthy. - www.sciencedaily.com
