“…After full-text evaluation, 16 articles were selected that provided information from 34 cohorts on sex differences in the association between smoking and stroke in the general population (Table). 5,6,15,16,[25][26][27][28][29][30][31][32][33][34][35] These data were extended with data from ARIC, 18 NHANES III, 19 APCSC, 20 and SHHEC, 21 adding a further 47 cohorts. Baseline characteristics of all 81 cohorts included in this study are described in the Table. Overall, data on 3 980 359 individuals were available, in whom ≥42 401 fatal and nonfatal strokes were documented (1 study, including 56 167 individuals, did not report the number of stroke events).…”

Thus, given the unequivocal link between smoking and stroke, Background and Purpose-It is currently unknown whether the excess risk of stroke by smoking is the same for women and men. We performed a systematic review and meta-analysis to estimate the effect of smoking on stroke in women compared with men. Methods-PubMed MEDLINE was systematically searched for prospective population-based cohort studies published between January 1, 1966, and January 26, 2013. Studies that presented sex-specific estimates of the relative risk of stroke comparing current smoking with nonsmoking and its associated variability were selected. The sex-specific relative risks and their ratio (RRR), comparing women with men, were pooled using random-effects meta-analysis with inverse variance weighting. Similarly, the RRR for former versus never smoking was pooled. Results-Data

“…Study participants were all aged o60 yrs, follow-up was generally short, and only one recent study was large (56,167 subjects). All studies showed that COPD mortality rates were higher in ex-than never-and current smokers, but the large cohort study from elderly health centres in Hong Kong followed for 3.2-5.0 yrs found that RRs of all-cause mortality in ex-smokers lay between those of never-and current smokers [54].…”

The evidence base for the benefit of quitting smoking as regards morbidity and mortality outcomes in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) is limited.The present article is a review of the existing literature. A systematic literature search in medical databases was performed until March 2006, and subsequently until September 1, 2007. The outcomes examined were COPD-related morbidity and mortality (including all-cause mortality) in COPD patients in connection with smoking cessation.A total of 21 and 27 published articles on morbidity and mortality, respectively, were identified and reviewed. For both outcomes, only a few of the studies included patients with severe COPD. Most of the studies reported a beneficial effect of smoking cessation compared with continued smoking, whereas a few found no improvement. Methodological problems, including small study sizes, poor data quality, possibility of reverse causality and incomplete ascertainment of cause of death, limit interpretation of some of the studies.The evidence as a whole supports the conclusion that, even in severe chronic obstructive pulmonary disease, smoking cessation slows the accelerated rate of lung function decline and improves survival compared with continued smoking.

“…Keil et al 2006). A newer case-control-study of Hong Kong-Chinese older than 65 years showed that tobacco abstinence is still beneficial at higher ages ("Quitting is beneficial") (Lam et al 2007). Surveys showed that approximately 70 % of all smokers would like to quit smoking and over 40 % have already tried at least once.…”

Smoking, quitting and mortality in an elderly cohort of 56 000 Hong Kong Chinese

Abstract: In old age, smoking continues to be a major cause of death, and quitting is beneficial. Smoking cessation is urgently needed in rapidly ageing populations in the East.
