Brief summary
A two-arm randomized controlled trial for smokers who are not intent to quit smoking will be proposed in outpatient department clinics of People's Liberation Army General Hospital in Beijing, China. Smoking reduction intervention arm (SRI) consisting of a very brief face-to-face individual smoking reduction intervention lasted about one minute, and five follow-up interventions lasted for about minute each. Control arm (EDA) consisting of a very brief face-to-face individual exercise and dietetic advices lasted for the same intervention time as SRI, and also five follow-up interventions lasted for one minute each with different intervention contents.
Interventions
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.
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.
