† Mothers who did not take part in any follow-ups were assumed not to have taken any action to help their husbands to give up.
‡ Mothers who only responded one or two follow-ups were assumed to have the same responses as those of the previous follow-up (‘carry-forward method’).
§ Any of the following actions counted: (1) helping husbands to set a date for giving up; (2) putting up a ‘No Smoking’ sign at home; (3) asking their husbands to read a quit-smoking health education booklet tailor-made for this study; (4) advising them to seek help from healthcare professionals; (5) encouraging them to stop smoking so that their children will be healthier and less likely to become smokers in the future; and (6) discussing matters with them to understand their needs during the quitting process.
¶ Excluding mothers who reported their husbands had already stopped smoking. Proxy reports of fathers’ smoking status: at 3-month follow-up (91 stopped, 1,392 still smoking); at 6-month follow-up (130 stopped, 1,353 still smoking); at 12-month follow up (153 stopped, 1,330 still smoking).
