Cigarette consumption and Risk of Coronary heart disease and Stroke

dc.contributor.authorAli, Hibba Hassan
dc.descriptionAround one billion adults worldwide smoke, with high prevalence in developing countries, where 49% of men and 11% of women use tobacco. Although the prevalence of current smokers has decreased over time in several countries, the global absolute number of smokers has increased owing to population growth. Policies have successfully encouraged people to quit, using aids such as nicotine replacement therapy and electronic cigarettes (e-cigarettes). In the Health Survey for England (2013 and 2014), 26% of current smokers reported that they wanted to cut consumption down but were not trying to stop, and 40-41% said that they smoked less than in the previous yeaen_US
dc.description.abstractTo use the relation between cigarette consumption and cardiovascular disease to quantify the risk of coronary heart disease and stroke for light smoking (one to five cigarettes/day). Medline 1946 to May 2015 design by Systematic review and meta-analysis. Prospective cohort studies with at least 50 events, reporting hazard ratios or relative risks compared with never smokers or age specific incidence in relation to risk of coronary heart disease or stroke. The meta-analysis included 55 publications containing 141 cohort studies. Among men, the pooled relative risk for coronary heart disease was 1.48 for smoking one cigarette per day and 2.04 for 20 cigarettes per day, using all studies, but 1.74 and 2.27 among studies in which the relative risk had been adjusted for multiple confounders. Among women, the pooled relative risks were 1.57 and 2.84 for one and 20 cigarettes per day. Men who smoked one cigarette per day had 46% of the excess relative risk for smoking 20 cigarettes per day, and women had 31% of the excess risk. For stroke, the pooled relative risks for men were 1.25 and 1.64 for smoking one or 20 cigarettes per day. In women, the pooled relative risks were 1.31 and 2.16 for smoking one or 20 cigarettes per day. The excess risk for stroke associated with one cigarette per day (in relation to 20 cigarettes per day) was 41% for men and 34% for women. Relative risks were generally higher among women than men. Smoking only about one cigarette per day carries a risk of developing coronary heart disease and stroke much greater than expected: around half that for people who smoke 20 per day. No safe level of smoking exists for cardiovascular disease. Smokers should aim to quit instead of cutting down to significantly reduce their risk of these two common major disorders.en_US
