Laten we onszelf gewoon eens bij de feiten houden. Wat dat betreft vertrouw ik sterke wetenschappelijke bewijslast boven de mening van wie dan ook... En helaas roxxe, meeroken is wel schadelijk.

Air pollution and lung cancer risks in China--a meta-analysis.
Lung cancer is a serious health problem in China, as in the rest of the world. Many studies have already proved that air pollution as well as other environmental factors can increase the risk of lung cancer. Based on epidemiological studies carried out in China, this paper proposes odds ratios (OR) to evaluate the risk of lung cancer from indoor air pollution for the Chinese population by applying the method of meta-analysis. For domestic coal use for heating and cooking, the pooled OR values are 1.83 (95% CI: 0.62-5.41) and 2.66 (1.39-5.07) for women and both coïtuses, respectively. For indoor exposure to coal dust, the OR values are 2.52 (95% CI: 1.94-3.28) and 2.42 (1.62-3.63) for women and both coïtuses, respectively. Cooking oil vapor is another factor increasing lung cancer risk. The OR values are 2.12 (95%CI: 1.81-2.47), 1.78 (1.50-2.12) and 6.20 (2.88-13.32) for nonsmoking women, women, and both coïtuses, respectively. Regarding environmental tobacco smoke, the pooled OR values are 1.70 (95% CI: 1.32-2.18) and 1.64 (1.29-2.07) for nonsmoking women and both coïtuses, respectively. Funnel plots with statistical test have been applied to examine the publication bias, and the results implied that the analysis of coal consumption and cooking oil pollution might be affected by publication bias. The meta-analysis results confirm the association between lung cancer and indoor air pollution for the Chinese population.
Revisiting evidence on lung cancer and passive smoking: adjustment for publication bias by means of "trim and fill" algorithm.
Meta-analyses are subject to bias because smaller or non-significant studies are less likely to be published, and most meta-analyses do not consider the effect of publication bias on their results. To assess the true risk, we revisited a famous meta-analysis including 37 studies on lung cancer and passive smoking, and adjusted for publication bias by means of the "trim and fill" algorithm. The adjusted relative risk of lung cancer in non-smokers who lived with a smoker from the 44 studies including the 7 filled ones was 1.19 (95% confidence interval 1.08-1.31, p = 0.0004), and the estimate of excess risk fell from 24 to 19%.

The impact of environmental tobacco smoke on women's risk of dying from heart disease: a meta-analysis.
OBJECTIVE: To review systematically and analyze the association between environmental tobacco smoke (ETS) exposure and the risk of dying from heart disease in women. METHODS: We searched the English-language literature using MEDLINE (1966-April 2004), CINAHL, PsychInfo, and bibliographies of selected studies. We included studies that specifically addressed the association of ETS and heart disease mortality in women and had adequate controls and retrievable risk estimates. We looked for either cohort studies or randomized controlled trials. Studies were evaluated independently by two of the authors. Nine cohort studies were finally selected for analysis. We estimated the summary relative risk (RR) and associated 95% confidence intervals (95% CI) using a random-effects model. RESULTS: Mean follow-up periods for these cohorts ranged from 6 to 39 years. Among non-smoking women, exposure to ETS was associated with a 15% increase in the risk of dying from heart disease compared with nonsmoking women not exposed to ETS (RR = 1.15, 95% CI 1.03-1.28, p < 0.05). CONCLUSIONS: Among nonsmoking women, exposure to passive smoke increases the risk of dying from heart disease. In accordance with the newly developed guidelines by the American Heart Association for prevention of cardiovascular disease (CVD) in women, we recommend counseling women on reducing or avoiding ETS exposure.
Passive smoking and coronary heart disease.
A large series of clinico-epidemiological studies, meta-analyses and experimental findings have concluded that there is a relationship between coronary heart disease (CHD) and passive smoking either after acute or chronic exposure. Cigarette smoking is the most important cause of premature death in industrialized countries because it is associated with an increased risk of developing several types of cancer and arterial disease. In family homes as well as in workplaces, environmental tobacco smoke (ETS) exposure is associated with an increased risk of CHD in exposed non-smokers when compared to un-exposed non-smokers. Different anatomical structures are damaged by ETS. The endothelium, artery wall and heart are target organs for passive smoking. Therefore, smoking cessation will benefit both smokers and those exposed to ETS.

Tobacco smoking and cancer: a brief review of recent epidemiological evidence.
This report summarises the epidemiological evidence on the association between tobacco smoking and cancer, which was reviewed by an international group of scientists convened by IARC. Studies published since the 1986 IARC Monograph on "Tobacco smoking" provide sufficient evidence to establish a causal association between cigarette smoking and cancer of the nasal cavities and paranasal sinuses, nasopharynx, stomach, liver, kidney (renal cell carcinoma) and uterine cervix, and for adenocarcinoma of the oesophagus and myeloid leukaemia. These sites add to the previously established list of cancers causally associated with cigarette smoking, namely cancer of the lung, oral cavity, pharynx, larynx, oesophagus, pancreas, urinary bladder and renal pelvis. Other forms of tobacco smoking, such as cigars, pipes and bidis, also increase risk for cancer, including cancer of the lung and parts of the upper aerodigestive tract. A meta-analysis of over 50 studies on involuntary smoking among never smokers showed a consistent and statistically significant association between exposure to environmental tobacco smoke and lung cancer risk. Smoking is currently responsible for a third of all cancer deaths in many Western countries. It has been estimated that every other smoker will be killed by tobacco.
