Predictors of intention to quit smoking in Hong Kong secondary school children.

BACKGROUND: Behavioral theories suggest that a past quit attempt influences psycho-social determinants to predict smokers' intention to quit, although no study has tested the hypothesis among youth smokers.
METHODS: A sample of 1561 Chinese secondary students, who were current smokers, were collected in a cross-sectional school-based survey in Hong Kong.
RESULTS: For the 943 students with past quit attempts, those with lower daily cigarette consumption; who perceived smoking would not elicit positive social responses from others; who had one parent/teacher who prohibited them to smoke; who were aware of the health hazards of smoking and being male smokers, were more likely to have an intention to quit smoking. For the 618 students without a past quit attempt, those who did not perceive any benefit from smoking; who had parents and teachers to prohibit them to smoke and who received social support to quit, were more likely to have an intention to quit smoking.
CONCLUSION: Strengthening the prohibition of smoking and providing social support may help initiate the intention to quit among youth smokers without a past quit attempt, while de-normalizing social images of smoking, providing information about the health hazards of smoking and relieving nicotine addiction may sustain quitting intentions among youth smokers with past quit attempts.
