About
This study aims to use a three arms randomized clinical trial study to evaluate the effectiveness of a video-led intervention in helping male smokers whose partner got pregnant in Mainland China to quit smoking.
Full description
With a globally growing number of smokers, up to about half of men and one tenth of women are becoming smokers and relatively few stopping, especially in Mainland China.
It has been proved that tobacco is responsible for even more deaths and diseases. Smokers have two to three times mortality in middle age among otherwise similar persons who had never smoked. According to the literature review, smoking has been confirmed to be an important risk factor to most chronic diseases and cancer.
For the male smokers at their reproductive ages, who is preparing to have a baby, smoking may negatively influence their reproductive capacity. Sufficient studies found that the quantity and duration of smoking, especially the current smoking is positively associated with the risk of erectile dysfunction. Smoking may increase the risk of a higher risk of developing oligospermia, asthenozoospermia and teratozoospermia for man in the reproductive years, which may lead to the inefficiency of fertilization and even give birth to abnormal fetus. Besides, secondhand Smoking (SHS) exposure also have further and longer negative effects on their female partner and their baby born in the future. The non-smoking population is much more sensitive to the nicotine in the passive smoking than smokers. The SHS may increase the risk of respiratory infections, ear problem, immediate adverse effects on cardiovascular system, lung cancer and so on to adults. For the children, the passive smoking make children have a higher chance to get severe asthma, slow lung growth. Hence, children and women live with smokers may have a higher risk of premature death and disease. Besides, newborns whose mothers were exposed to secondhand smoke showed significantly lower scores in the habituation cluster and motor system cluster, as well as the delay of neurobehavioral development regardless of socio-demographic, obstetric and pediatric factors. Conclusively, smoking has direct and indirect negative effect to male smokers in reproductive ages themselves and their family members.
Based on the official statistic figures in 2010, about one third of people in China were current smokers, and the number of young smokers is increasing. While most current smokers (83.9%) report having no intention to quit smoking (WHO, 2011). On average, between 60% and 70% of Chinese men continue to smoke into middle age, which is different with the western countries. Hence, finding out a solution to decrease the married reproductive male smoking rate is extremely crucial.
Overall awareness of the health hazards of tobacco has improved in the last 15 years in China, but is still relatively poor. Even there were several patterns of propaganda and education applied in China, the efficiency is not very satisfactory. Hence, an effective education interventions that delivery the health hazards of tobacco to male smokers and secondhand smoking to their wives and baby born in the future should be developed and implemented for reproductive male smokers in China.
Different patterns of interventions, such as counselling, advertising, leaflets and so on have been implemented, however the effect is not so well as we expected. Thus, a more efficient intervention should be developed. As the high usage rate of smart phone, interventions implemented by cellphone can be considered as a new approach. Watching video has been proven to be significantly associated with prevalence abstinence. Video, combining with the advantage of text, image, and tones, will take visual, auditory and reading stimulation to the brain, consequently, enhance the delivery and memory of information for people. Hence video is an efficient intervention medium for smoking cessation.
Given that, a video-led intervention will be applied to help male smokers whose partner got pregnant in Mainland China to quit or reduce the cigarette smoking.
