Price and cigarette consumption in Europe.

OBJECTIVE: To analyse the variation in demand for tobacco according to price of cigarettes across the European region. DESIGN: Cross-sectional study. SETTING: All the 52 countries of the European region. PARTICIPANTS: For each European country, data were collected on annual per adult cigarette consumption (2000), smoking prevalence (most recent), retail price of a pack of local and foreign brand cigarettes (around 2000), the gross domestic product adjusted by purchasing power parities, and the adult population (2000). MAIN OUTCOME MEASURE: Price elasticity of demand for cigarettes (that is, the change in cigarette consumption according to a change in tobacco price) across all the European countries, estimated by double-log multiple linear regression. RESULTS: Controlling for male to female prevalence ratio, price elasticities for consumption were -0.46 (95% confidence interval (CI) -0.74 to -0.17) and -0.74 (95% CI -1.13 to -0.35) for local and foreign brand, respectively. The inverse relation between cigarette price and consumption was stronger in countries not in the European Union (price elasticity for foreign brand cigarettes of -0.8) as compared to European Union countries (price elasticity of -0.4). CONCLUSIONS: The result that, on average, in Europe smoking consumption decreases 5-7% for a 10% increase in the real price of cigarettes strongly supports an inverse association between price and cigarette smoking.

[Smoking cessation in a population-based cohort study].

OBJECTIVE: To study the incidence rates and the determinants of smoking cessation in a population-based cohort. MATERIAL AND METHODS: We used data from the Cornellà Health Interview Survey Follow-up Study. Subjects who declared they were daily smokers at baseline (1994) and had complete follow-up, with information on smoking status in 2002, entered into analysis. We calculated incidence rates and the relative risks of cessation (with 95% confidence intervals) using the Cox model. RESULTS: Out of 353 daily smokers, 100 quit smoking during the follow-up period (cumulative incidence of 28.3%). The incidence rate of cessation was higher among men (42.34 per 1000 person-years) than among women (24.97 per 1000 person-years), with a relative risk of cessation of 1.69 (95% confidence interval, 1.02-2.79) for men. Age and level of education were associated with a higher relative risk of quitting in men. CONCLUSIONS: The main determinants for smoking cessation are sociodemographic (sex, age, and level of education).

Price and consumption of tobacco in Spain over the period 1965-2000.

Changes in cigarette price have had an appreciable impact on smoking prevalence in several countries. We analysed the price elasticity of demand for cigarettes (effect of price of cigarettes on tobacco consumption) between 1965 and 2000 in Spain. For total consumption of cigarettes, a 1% increase in price is associated with a 0.19% decrease of consumption (price elasticity of -0.19; P<0.01). The real price of blond cigarettes was significantly and inversely associated with blond cigarette consumption: on average, smoking prevalence decreased 1.25% for a 1% increase in the real price of cigarettes (significant price elasticity of -1.25). For black cigarettes we found a lower but still high and significant elasticity of -0.61. There is an inverse relation between price and consumption of cigarettes in Spain, indicating that interventions at the economic level (such as real increases in prices) may have an important public health impact in tobacco control.

Prevalence of cigarette smoking by birth cohort among males and females in Spain, 1910-1990.

We analysed the prevalence of cigarette smoking among subsequent birth cohorts of Spanish males and females. Data were drawn from the Spanish NHIS conducted in 1993 ( = 26 400), 1995 ( = 8300) and 1997 ( = 8300). From the original computer files, the three surveys were pooled to obtain a single sample. A total of 33 223 subjects (16 036 men and 17 187 women) born between 1900 and 1979, >/= 16 years old, were directly interviewed and with complete information on the history of smoking included for analysis. Based on each respondent's sex and calendar year of birth, the person was classified into a particular sex-birth cohort in the decades from 1900-09 to 1970-79. For each year from date of birth to date of survey, respondents were further classified as either cigarette smoker or nonsmoker. The prevalence of cigarette smoking among successive cohorts of Spanish men and women was estimated, with correction for excess mortality of smokers. In men, the peak in smoking was reached in the 1950-59 birth cohort (prevalence rate of 68% at ages 20-29), after increases during the previous calendar years. Smoking among women was rare until 1960. Female smoking prevalence rates increased progressively among subsequent cohorts until 1980. The age distribution of smoking prevalence in women in 1990 mimics that observed in men 40 years earlier. A substantial delay in the spread of the tobacco epidemic among men is apparent. In women, the delay in the initiation of the smoking epidemic ended with a quick diffusion of the habit.

Price and consumption of tobacco in Italy over the last three decades.

Changes in cigarette price have had an appreciable impact on smoking consumption in several countries. We analysed the price elasticity of demand for cigarettes in Italy over the period 1970-2001. A 1% increase in price of cigarettes led to a 0.30% decline in smoking prevalence and to a 0.43% decline in cigarette consumption. The present analyses confirm the existence of an inverse association between price and prevalence/consumption of cigarettes in Italy, and indicate that economic aspects may have important public health implications in tobacco control.

Smoking initiation and cessation by gender and educational level in Catalonia, Spain.

BACKGROUND: The role of gender and socioeconomic status in smoking has been characterized in the United States and Northern European countries. However, there is scarce information of the dynamic of the tobacco epidemic in Southern European countries. The aim of this study was to analyze smoking initiation and cessation according to level of education and gender in Catalonia, Spain. METHODS: Data from the Catalan Health Survey (1994), a cross-sectional study based in a representative sample of the noninstitutionalized population of Catalonia, was used. The relative risks and 95% confidence interval of smoking initiation were computed by means of Cox's regression. The odds ratios and 95% confidence intervals of quitting smoking were derived from logistic regression models. Direct responses from 4,370 men and 5,213 women ages 25 years or over were included for analysis. RESULTS: Ever smoking was inversely related to level of education in men. Males with the highest educational level tended to have a lower probability of being a smoker at a given age than those with less than primary school (relative risk = 0.6; 95% confidence interval: 0.5-0.7). This pattern appeared with small variation across age groups. In women, a reverse trend was present: the higher the level of education the higher the relative risk of starting smoking (relative risk = 4.6; 95% confidence interval: 3.1-6.7). Quitting smoking was more likely among men and women with higher education as compared to men and women with less than primary school (men: odds ratio = 1.5; 95% confidence interval 1.1-2.1; women: odds ratio = 4.6; 95% confidence interval: 2.1-10.4). CONCLUSIONS: The differential effect of education according to gender may reflect different phases of the smoking epidemic. In Catalonia, the transition of smoking from upper and lower socioeconomic groups occurred recently among men, and women have currently begun to experience this transition.

Social class inequalities in the use of and access to health services in Catalonia, Spain: what is the influence of supplemental private health insurance?

OBJECTIVE: To analyse social class inequalities in the access to and utilization of health services in Catalonia (Spain), and the influence of having private health insurance supplementing the National Health System (NHS) coverage. DESIGN: 1994 Catalan Health Interview Survey, a cross-sectional survey conducted in 1994. SETTING: Catalonia (Spain). STUDY PARTICIPANTS: The participants were a representative sample of people aged over 14 years from the non-institutionalized population of Catalonia (n = 12,245). MAIN OUTCOME MEASURES: Health services utilization, perceived health, having only NHS or NHS plus a private health insurance, and social class. RESULTS: Although one-quarter of the population of Catalonia had a supplemental private health insurance, percentages were very different according to social class, ranging from almost 50% for classes I and II to 16% for classes IV and V in both sexes. No inequalities by social class were observed for the utilization of non-preventive health care services (consultation with a health professional in the last 2 weeks and hospitalization in the last year) among persons with poor self-perceived health status, i.e. those in most need. However, social inequalities still remain in the use of health services provided only partially by the NHS, and when characteristics of last consultation are taken into account. Subjects who paid for a private service waited an average of 18.8 minutes less than those attending the NHS. Within the NHS, social classes IV and V waited longer (35.5 minutes) than social classes I and II (28.4 minutes). CONCLUSION: The NHS in Catalonia, Spain, has reduced inequalities in the use of health services. Social inequalities remain in the use of those health services provided only partially by the NHS.

[Inequalities in health according to social class in Catalonia, 1994].

OBJECTIVE: To study social inequalities in health in Catalonia. DESIGN: Cross-sectional survey of a representative sample of the population of Catalonia, Spain (Catalan Health Interview Survey, 1994). PARTICIPANTS: Responses from 5641 males and 6604 women aged 15 years or over were included for analysis. MEASUREMENTS AND MAIN RESULTS: We analysed the information about self-perceived health, restriction of activity, and presence of chronic conditions according to social class by means of logistic regression models. The proportion of subjects that rated their health as fair or poor was higher in social classes IV-V than in classes I-II (men: 25.0% vs. 14.5%; OR, 1.8, 95% CI, 1.5-2.3; women: 34.4% vs. 21.5%; OR, 1.7, 95% CI, 1.4-2.1). There were differences by social class in respect to restriction of activity and presence of chronic conditions. CONCLUSIONS: Despite the decrease of social inequalities in accesibility and use of health services due to the universalisation of health coverage, differences by social class remain in the perception of health status. These inequalities should be addressed by the health system within the framework of broad public and social policies.

[Cancer mortality in Spain, 1955-1994].

BACKGROUND: To analyze the mortality from the eight main cancer sites in men and women from Spain between 1955-1994. MATERIAL AND METHODS: Age-standardized mortality rates were computed. RESULTS: In men, an increase in lung cancer mortality as well as in the other 8 sites was registered, except for stomach cancer. In women, breast, ovary, and pancreas cancer mortality continue to increase. CONCLUSIONS: Cancer mortality in Spain has dismal trends. This fact implies the need of strong interventions.

The quality of care and influence of double health care coverage in Catalonia (Spain).

AIMS: To analyse inequalities by social class in children's access to and utilisation of health services in Catalonia (Spain), private health insurance coverage, and certain aspects of the quality of care received. DESIGN: Cross sectional study using data from the 1994 Catalan Health Interview Survey. SETTING: Child population of Catalonia. PARTICIPANTS: A representative sample of non-institutionalised children younger than 15 years (n = 2433). MAIN OUTCOME MEASURES: Health services utilisation, perceived health, type of health insurance (only National Health System (NHS) or both NHS and private health insurance), and social class. RESULTS: No inequalities by social class were found for the utilisation of health care services provided by the NHS among children in most need. Double health care coverage does not influence the social pattern of visits. Nevertheless, social inequalities still remain in the use of those health services provided only partially by the NHS (dentist) and when characteristics of the last consultation are taken into account. That is, subjects who paid for a private service waited an average of 14.8 minutes less than those whose visit was paid for by the NHS only. CONCLUSION: Equitable access and use of medical care services in relation to need, regardless of the type of insurance and social class of their children and families, has been achieved in this region of Spain; differences by social class remain for those services incompletely covered by national health insurance and aspects of the quality of care provided.

Pattern of smoking initiation in Catalonia, Spain, from 1948 to 1992.

OBJECTIVES: This study analyzed the pattern of smoking initiation by sex and educational level in Catalonia, Spain. METHODS: Data from the 1994 Catalan Health Interview Survey were used (n = 12,245). The age and smoking status of each subject were reconstructed for each calendar period. Age-specific smoking initiation rates were calculated. RESULTS: Smoking initiation among females was rare until the 1960s, but from the period 1968-1972 onward a converging pattern was observed between the genders. Women with higher levels of education started smoking before other women, but the gradient of educational level has changed in recent years, with higher initiation rates among less-educated women. CONCLUSIONS: These results are consistent with diffusion-of-innovations theory and could be related to social and economic changes from the 1960s onward in Spain.

Age at starting smoking and number of cigarettes smoked in Catalonia, Spain.

BACKGROUND: Few studies have investigated the association between age at starting smoking and the average number of cigarettes smoked per day in adulthood. To provide further evidence on this issue, we analyzed data from the Catalan Health Interview Survey (CHIS). METHODS: The CHIS was conducted in 1994 on a randomly selected sample (N = 15,000) of the population of Catalonia, Spain. A total of 4,897 current or exsmokers (3,276 males and 1,621 females) were included for analysis. Age-standardized proportions of subjects smoking <15, 15-24, and >/=25 cigarettes/day, age-standardized mean number of cigarettes smoked per day, and multivariate odds ratios (OR) of being a heavy smoker (>/=25 cigarettes/day) according to age at starting smoking (<15, 15-17, 18-19, >/=20 years) were computed. RESULTS: Men who started smoking before the age of 15 smoked on average 5.5 cigarettes more than those who started at age 19 or over. Women who started smoking early in life smoked, on average, 6.8 cigarettes/day more than women who started later. The proportion of smokers of <15 cigarettes/day was higher among subjects who started smoking later. Both for males and for females, the OR of being a heavy smoker significantly increased with decreasing age at starting smoking (OR = 2.4 for males and 4.5 for females who started at age <15 versus >/=20 years). The level of education did not modify the relationship in males, whereas the association with age at starting was only apparent for more educated women. CONCLUSIONS: This study confirms that age at starting smoking is inversely and strongly associated to the number of cigarettes smoked per day. Thus, actions aimed at the prevention or delay of smoking onset among adolescents would have an important beneficial effect.

Determining correspondence between scores on the EQ-5D "thermometer" and a 5-point categorical rating scale.

BACKGROUND: "Feeling thermometers" and category rating scales (CRS) can be used to measure self-rated health, though the interpretation of scores on the feeling thermometer may be problematic. OBJECTIVES: To analyze correspondence between scores of self-rated health on the EuroQol-5D "feeling thermometer" and a five-Point CRS. To determine the influence of sociodemographic variables on correspondence. RESEARCH DESIGN: Correspondence between EQ-5D "thermometer" scores and CRS categories was determined in a within-subjects design using data from a large-scale health survey. SUBJECTS: Twelve thousand, two hundred and forty-five members of the Spanish general population interviewed in the Catalan Health Interview Survey. MEASURES: Instruments used were the EQ-5D "feeling thermometer" and a five-Point CRS with categories from "excellent" to "poor." RESULTS: Median scores on the thermometer corresponding to CRS categories were as follows: poor = 40; fair = 53; good = 76; and very good = 80; excellent = 90; differences were statistically significant (P < 0.05). Ranges in thermometer scores covered by CRS categories varied from 23.5 points for the category "poor" to 13 points for the category "very good" (range, 25-75 percentiles), with considerable overlap between categories at the upper end of the scale. Median thermometer scores corresponding to the categories "good,""fair," and "poor" were lower in older respondents and in those with a lower educational level. CONCLUSIONS: Determining correspondence between CRS and thermometer scores is useful in interpreting and categorizing thermometer scores. The age and level of education in particular affect the interpretation of CRS categories, and should be taken into account when analyzing results obtained with such instruments.

Gender inequalities in health and health care services use in Catalonia (Spain).

BACKGROUND AND OBJECTIVES: While socio-economically derived differences in health and health services use have long been a subject of study, differences based on gender, considered as the explicative variable, have scarcely been quantified from population-based data. The aim of this investigation was to analyse inequalities in health and health care services utilisation between men and women in Catalonia (Spain). DESIGN, SETTING, PARTICIPANTS, AND MEASURES: Data from the Catalan Health Interview Survey, a cross sectional survey conducted in 1994, were used. A total of 6604 women and 5641 men aged 15 years or over were included for analysis. Health related variables studied were self perceived health, restriction of activity (past two weeks), and presence of chronic conditions; health services use variables analysed were having visited a health professional (past two weeks), an optometrist (12 months), or a dentist (12 months); and hospitalisation (past 12 months). Age standardised proportions were computed according to gender, and prevalence odds ratios (OR) were derived from logistic regression equations. MAIN RESULTS: Women more frequently rated their health as fair or poor than men (29.8% v 21.4%; OR = 1.22; 95% CI: 1.10, 1.34). More women than men reported having restricted activity days (OR = 1.86; 95% CI: 1.59, 2.18) and chronic conditions (OR = 1.74; 95% CI: 1.60, 1.89). The proportion of women visiting a health professional was slightly greater than that for men (OR = 1.20; 95% CI: 1.09, 1.31), as was the proportion of women visiting an optometrist (OR = 1.21; 95% CI: 1.11, 1.33), and a dentist (OR = 1.43; 95% CI: 1.31, 1.55). The proportion of hospitalisation was lower in women (6.6%) than in men (7.7%; OR = 0.73; 95% CI: 0.63, 0.85). When health services use was analysed according to self perceived health, women declaring good health reported a greater probability of consulting a health professional (OR = 1.35; 95% CI: 1.20, 1.52). There were no differences in respect to hospitalisation, visits to the optometrist and to the dentist. CONCLUSIONS: These results indicate a pattern close to the inverse care law, as women, who express a lower level of health and thus would need more health care, are not, however, using health services more frequently than men.
