Study arms

  • Experimental
    Smoking reduction intervention arm

    Smoking reduction intervention arm (SRI) consisting of a minimal face-to-face individual smoking reduction intervention lasted for about one minute, and five follow-up interventions lasted for about one minute each.

    Behavioral: Smoking reduction intervention

  • Active comparator
    Control arm

    Control arm (UC) consisting of a brief face-to-face individual exercise and dietetic advices lasted for the same intervention time as SRI, and five follow-up interventions lasted for about one minute each with different intervention contents.

Interventions

  • BehavioralSmoking reduction intervention

    Smokers was informed that many harmful effects were proved to be related with smoking, such as cancer, coronary heart disease, respiratory disease and many other health problems, and one out of two smokers will be killed by smoking. Smokers will be advised to reduce smoking consumption for at least half of their total consumption in the next month. Finally, all smokers were warned to keep in mind that the current attempt to reduce smoking is an intermediate step before the complete cessation.

  • BehavioralExercise and diet advice control

    Smokers will be asked to do regular activities for three or four times per week, and to have a healthy and balanced diet, having more fruit and vegetables which are rich in vitamins, high in nutrition yet low in calories. In the whole process, advises will not refer to smoking cessation or smoking reduction.
