Background. Electronic cigarettes (e-cigarettes) are small battery-powered electronic devices, heating the liquid to produce vapour – in most cases the latter contains nicotine and several flavourings. E-cigarettes are highly advertised across the media, mainly as healthy substitute to conventional cigarettes, aid in quitting smoking addiction or way of circumventing ban on smoking in public places. Objective. The aim of study was obtaining epidemiological data on cigarette smoking and electronic cigarette usage among Polish universities students. Material and methods. Students of different Polish state universities were asked to fill a self-prepared survey on cigarettesmoking and electronic cigarette usage. 1068 fulfilled questionnaires were gathered. The population was divided into two subgroups – medical universities’ students (n=545) and non-medical universities students (n=523). Results. 23.78% of respondents declared current smoking while 57.0% admitted ever smoking. The mean duration of smoking among current smokers was 4.17 ± 2.53 years. 56.30% of current smokers tried quitting at least once. 31.46% of students declared ever using e-cigarettes (37.28% (n=195) among non-medical universities’ students and 25.87% (n=141) among medical universities’ students and 8.33% current usage. Among the latter 52.81% admitted simultaneous smoking. 26.97% of current e-cigarettes’ users declared having experienced side effects of e-cigarettes. 42.70% (n=456) of respondents viewed e-cigarettes as safer than conventional cigarettes, this group comprises of 40.54% (n=212) non-medical and 44.77% (n=244) medical universities’ students. 85.39% (n=912) of students viewed e-cigarettes as generally unhealthy, there were 83.56% (n=437) non-medical and 87.16% (n=475) medical universities’ students among this group. Conclusions. The frequency of e-cigarettes usage resembles current status in many Western countries. Collected data shows high frequency of e-cigarettes usage and conventional cigarettes smoking among students (also medical universities’ students). The situation requires intensive preventive measures to limit and reduce the popularity of tobacco products along with modern equivalents like electronic cigarettes.
Tobacco smoking is a major avoidable single cause of premature mortality in Poland. Almost one in three Polish males do not live to 65 years of age, and almost half of this premature mortality can be traced back to the much higher smoking prevalence in Poland than in Western Europe – every third Polish male and every fourth Polish female smokes daily. However, the current health situation in Poland is much better than two decades ago when the country entered a period of political and economic upheaval. In the early 1990s, the state of health of the Polish population was catastrophic and its tobacco consumption levels the highest in the world. In the early 1990s, the probability of a 15-year-old Polish boy living to the age of 60 was not just twice lower than in Western Europe, but also lower than in China or India. The health policy of limiting the health consequences of smoking conducted by the European Union and, in the last two decades, by the Polish parliament and government, helped to stop this health catastrophe. In Poland, cigarette consumption has decreased by 30% since 1990, as did lung cancer mortality among males. Despite this progress, tobacco smoking remains the most serious health problem in Poland. Therefore, comprehensive tobacco control policy should not only be continued, but expanded and accelerated. The EU Tobacco Products Directive proposes a package of actions for reducing tobacco-related health harm in Europe. The Directive proposal is rational, science-and-evidence based, and grounded on the best practice examples from other countries. Both the Polish tobacco control law and the WHO Framework Convention on Tobacco Control (FCTC), ratified by Poland in 2006, oblige our country to support tobacco control, including all the initiatives taken by the European Union.
Cotinine, as the main metabolite of nicotine, has been determined in urine using solid-phase extraction and the high-performance thin-layer chromatographic (SPE-HPTLC) method. The urine samples were collected from a group of 35 male adolescents which were moderate or significantly exposed to home environmental tobacco smoke (ETS). l-methyl-2-pyrrolidinone was used as the internal standard in the proposed screening procedure. The thin-layer chromatograms were evaluated densitometrically after visualization of cotinine spots with ninhydrin and cadmium acetate solution. The described SPE-HPTLC procedure indicated good selectivity, sensitivity and reproducibility, enabling reliable verification of interview collected questionnaire data in families exhibiting a diversified level of ETS. The results of cotinine measurements by the proposed method were applied for assessment of hazards from home ETS on the health status of elementary schoolboys, especially an increased risk for infectious respiratory tract diseases and exercise-induced bronchospasm.
The study on the prevalence of overweight and obesity involved 3181 women doing mental and physical work. In studied women body height and weight were measured and BMI was calculated to estimate if they were overweight or obese. The per cent of women with overweight and obesity increased with age in both groups. The prevalence of these abnormalities was more frequent in physical workers than in women doing mental work. Overweight and obesity were connected also with the place of residence and tobacco smoking.
High plasma levels of fibrinogen and plasminogen activator inhibitor (PAI-1) are reported to be correlated with coronary heart disease. Therefore the level of fibrinogen concentration in plasma was examined and verified for the possible correlation with the previously explored PAI-1 antigen and PAI-1 activity in the pathogenesis of premature atherosclerosis (Grzywaczet al., 1998,Blood Coagul Fibrinol. 9, 245-249). Examination included only men, aged 33-46 years, who were in a stable condition for at least six months after the acute event. They were divided into two subgroups: group A (n = 14) with and group B (n = 15) without ischaemic changes in 24 h Holter electrocardiogram. The number of involved vessels visible on the coronarography picture was similar in both groups. In the patients of group A the mean level of fibrinogen (3.92 vs 3.23 g/l, P < 0.05) was higher than in the controls (n = 15). No statistically differences were found between group B and control healthy subjects in any of the parameters measured. There were no correlation between fibrinogen concentration and PAI-1 antigen and activity levels, which were elevated in both groups of patients according to our previous study. Our results indicate that elevated levels of plasma fibrinogen and PAI-1 appeared in the group of patients with more severe disease, as revealed by silent myocardial ischaemia.
Single-strand breaks (SSB) and DNA repair were detected in peripheral lymphocytes derived from workers of a furniture factory in a non-polluted region of Poland. The workers were exposed to wood dust (n = 19), or to the dust and varnishes or lacquers together (n = 5). Four groups were studied simultaneously: (a) exposed workers smokers of cigarettes (n = 14), (b) nonexposed smokers - control (n = 14), (c) exposed workers' nonsmokers (n = 14), (d) exposed nonsmokers (n = 10). In exposed workers DNA SSB and DNA repair were statistically significantly increased. DNA SSB was clearly higher in the smoking workers than in the smoking controls. Cigarette smoking itself has produced no evident increase in the frequency of DNA SSB in the control group. Occupational exposure had a significant effect on DNA repair in non stimulated lymphocytes both in smoking and nonsmoking workers.
