Association between population prevalence of smoking and incidence of meningococcal disease in Norway, Sweden, Denmark and the Netherlands between 1975 and 2009: a population-based time series analysis.

OBJECTIVE: To investigate the relationship between the prevalence of smoking in the population and incidence of invasive meningococcal disease (IMD) among children under 5 years of age. DESIGN: Retrospective, longitudinal, observational study. Poisson regression controlled for confounding factors. SETTING: Norway, Sweden, Denmark and the Netherlands between 1975 and 2009. POPULATION: Total population of approximately 35 million people in these four countries. DATA SOURCES: Data were collected from the Ministries of Health, National Statistics Bureaus and other relevant national institutes. RESULTS: In Norway, there was a significant positive relationship between the annual prevalence of daily smokers among individuals aged 25-49 years and the incidence of IMD in children under 5 years of age, unadjusted (RR=1.04-1.06, 95% CI 1.02 to 1.07, p<0.001) and after adjustment for time of year (quarter), incidence of influenza-like illness and household crowding (RR=1.05-1.07, 95% CI 1.03 to 1.09, p<0.001). Depending on age group, the risk of IMD increased by 5.2-6.9% per 1% increase in smoking prevalence among individuals aged 25-49 years in adjusted analyses. Using limited datasets from the three other countries, unadjusted analysis showed positive associations between IMD in children related to older smokers in Sweden and the Netherlands and negative associations related to younger smokers in Sweden. However, there were no demonstrable associations between incidence of IMD and prevalence of smoking, after adjustment for the same confounding variables. CONCLUSIONS: The reduced incidence of IMD in Norway between 1975 and 2009 may partly be explained by the reduced prevalence of smoking during this period. High-quality surveillance data are required to confirm this in other countries. Strong efforts to reduce smoking in the whole population including targeted campaigns to reduce smoking among adults may have a role to play in the prevention of IMD in children.

Impact of tobacco control policy on quitting and nicotine dependence among women in five European countries.

OBJECTIVE: To describe differences in and factors associated with former smoking and nicotine dependence among women in Ireland, Sweden, France, Italy and the Czech Republic. METHODS: A cross-sectional, random digit dial telephone survey of 5000 women, aged 18 years and older, conducted in 2008. Analyses were conducted using logistic regression models. RESULTS: Respondents from Ireland and Sweden had statistically significantly higher odds of having quit smoking within the 5 years before survey administration compared with respondents from the Czech Republic. Current smokers from Ireland, Sweden, France and Italy are more nicotine dependent than those from the Czech Republic. CONCLUSIONS: Respondents from countries with stronger tobacco control policies were more likely to have quit smoking compared with those living in the Czech Republic. However, respondents in countries with some of the strongest policies (Ireland, Sweden, France and Italy) had higher odds of smoking within 30 min of waking, an established indicator of nicotine dependence. More research in this area is warranted, but this study suggests that now that the Czech Republic is beginning to implement strong tobacco control policy, they will probably achieve a rapid decline in population-level smoking. Ireland, Sweden, France, Italy and other countries with established, strong tobacco control policies would do well to consider what additional programmes they can put in place to help their highly nicotine-dependent population of smokers successfully quit.

Attitudes of women from five European countries regarding tobacco control policies.

AIMS: Tobacco-related cancers and, in particular, lung cancer still represents a substantial public health epidemic across Europe as a result of high rates of smoking prevalence. Countries in Europe have proposed and implemented tobacco control policies to reduce smoking prevalence, with some countries being more progressive than others. The aim of this study was to examine factors that influenced women's attitudes across five European countries relative to comprehensive smokefree laws in their countries. METHODS: A cross-sectional landline telephone survey on attitudes towards tobacco control laws was conducted in five European countries: France, Ireland, Italy, the Czech Republic, and Sweden. Attitudinal scores were determined for each respondent relative to questions about smokefree laws. Logistic regression models were used to obtain odds ratios with 95% confidence intervals. RESULTS: A total of 5000 women were interviewed (1000 women from each country). The majority of women, regardless of smoking history, objected to smoking in public buses, enclosed shopping centers, hospitals, and other indoor work places. More women who had quit smoking believed that new tobacco control laws would prompt cessation - as compared with women who still smoked. CONCLUSIONS: In general, there is very high support for national smokefree laws that cover bars, restaurants, and public transport systems. As such laws are implemented, attitudes do change, as demonstrated by the differences between countries such as Ireland and the Czech Republic. Implementing comprehensive smokefree laws will gain high approval and will be associated with prompting people to quit.

Knowledge and beliefs about smoking and cancer among women in five European countries.

BACKGROUND: Lung cancer mortality in women is increasing across Europe, reflecting the alarming increase in smoking prevalence. Understanding women's perception of smoking may help to identify ways to reduce its prevalence and prevent uptake of smoking. The aim of this study was to examine factors associated with knowledge and beliefs about smoking and cancer among European women. METHODS: A cross-sectional landline telephone survey on health attitudes and knowledge was conducted in five European countries: France, Ireland, Italy, the Czech Republic, and Sweden. A general linear modeling was used to explore the factors related to knowledge and beliefs about smoking and cancer. RESULTS: A total of 5,000 women were interviewed (1,000 women from each country). The mean knowledge and belief scores about smoking and cancer were lower in current smokers than those of never and former smokers (P < 0.05). Women with above-the-median income (P = 0.001) and women who held skilled occupations seemed to be more knowledgeable about tobacco health risks (P < 0.001). The number of friends and family who smoked was inversely associated with knowledge on the harmful effects of tobacco (P = 0.001). Swedish women were the most knowledgeable about tobacco-related cancer risk, whereas in France and Italy, current smokers were less knowledgeable. CONCLUSIONS: Knowledge and beliefs about cancer and smoking varied significantly by smoking status. IMPACT: Results emphasize the need to develop health education programs that enhance cancer knowledge among women who currently smoke and are in low socioeconomic groups.

Determinants of smoking initiation among women in five European countries: a cross-sectional survey.

BACKGROUND: The rate of smoking and lung cancer among women is rising in Europe. The primary aim of this study was to determine why women begin smoking in five different European countries at different stages of the tobacco epidemic and to determine if smoking is associated with certain characteristics and/or beliefs about smoking. METHODS: A cross-sectional telephone survey on knowledge and beliefs about tobacco was conducted as part of the Women in Europe Against Lung Cancer and Smoking (WELAS) Project. A total of 5,000 adult women from France, Ireland, Italy, Czech Republic, and Sweden were interviewed, with 1,000 from each participating country. All participants were asked questions about demographics, knowledge and beliefs about smoking, and their tobacco use background. Current and former smokers also were asked questions about smoking initiation. Basic statistics on the cross-sectional data was reported with chi-squared and ANOVA p-values. Logistic regression was used to analyze ever versus never smokers. Linear regression analyses were used to analyze age of smoking initiation. RESULTS: Being older, being divorced, having friends/family who smoke, and having parents who smoke were all significantly associated with ever smoking, though the strength of the associations varied by country. The most frequently reported reason for initiation smoking was friend smoking, with 62.3% of ever smokers reporting friends as one of the reasons why they began smoking. Mean age of smoking initiation was 18.2 years and over 80% of participants started smoking by the age of 20. The highest levels of young initiators were in Sweden with 29.3% of women initiating smoking at age 14-15 and 12.0% initiating smoking younger than age 14. The lowest level of young initiators was in the Czech Republic with 13.7% of women initiating smoking at age 14-15 and 1.4% of women initiating smoking younger than age 14. Women who started smoking because their friends smoked or to look 'cool' were more likely to start smoking at a younger age. Women who started smoking to manage stress or to feel less depressed were more likely to start smoking at an older age. CONCLUSIONS: In all five participating countries, friends were the primary factor influencing ever smoking, especially among younger women. The majority of participants began smoking in adolescence and the average reported age of smoking initiation was youngest in Sweden and oldest in the Czech Republic.

Trends of tobacco use in Sweden and Finland: do differences in tobacco policy relate to tobacco use?

BACKGROUND: Sweden and Finland, neighbouring countries in Scandinavia, share features in health and social policies but retain a few differences in tobacco policy, including oral tobacco product regulation. This paper analyses the differences between tobacco policy and tobacco use between these two countries. MATERIAL: Representative data sets from both countries, for age groups 18 to 64, were used to compare the status of tobacco use. The study covered the years 1988/89, 1996/97 and 2004/05. RESULTS: Among men, daily use of tobacco products is more common in Sweden than in Finland. The daily smoking rate for men in Sweden is 16% compared to 28% in Finland. In Sweden, 27% of men use snuff daily and 17% of never smoking men reported daily use of snuff. In Finland, 3% of all males report daily use of snuff. Concurrent snuff use was linked to occasional smoking in Sweden, where 23% of male daily snuff users smoke occasionally. Among women smoking prevalence has decreased significantly in Sweden during the study period, but no real change in daily smoking can be detected in Finland. CONCLUSIONS: Tobacco control measures did gain good results among women in Sweden whereas in Finland development was modest. In Sweden, tobacco use has increased mainly due to an increase in snuff use, and snuff seems to appeal not only to switchers, but to young males without a history of smoking.
