AIDS-related knowledge and behaviors in Mozambique.

BACKGROUND: The objective of this study was to describe attitudes and knowledge about AIDS among the population aged 15 to 49 in Chókwè (Mozambique) during the period from March to May 2004, and to study associated factors. METHODS: Cross-sectional study conducted by interviewing 1,055 people aged 15 to 49, of both sexes, residents in Chókwè (68,698 inhabitants). The questionnaires employed are known as the Behavior Surveillance Survey. Dependent variables were: knowledge about transmission routes and preventive methods, use of condoms and having had sexual relations with an irregular partner during the past 12 months. Odds ratios were calculated for the association between these variables and age, sex, educational level, neighborhood of residence, number of relations in the last 30 days, and whether AIDS tested, by fitting Logistic Regression models (bivariate and multivariate). RESULTS: Over 99% of the sexually active population of Chókwè knew about AIDS and condoms. More than half of the population of Chókwè has a good knowledge of preventive methods and of transmission routes. 72.9% of men and 91.3% of women did not use the condom when having sexual relationships. It was observed that a low educational level implied a lower degree of knowledge about preventive methods (OR=2.48, 95% CI: 1.60-3.84) and about transmission routes (OR=2.49, 95% CI: 1.37-4.52), less condom use and less relations with irregular or sporadic partners. The probability of not using condoms was higher among females, among people living in less privileged districts, with no education (OR=3.79; 95% CI: 1.80-7.99), with regular partners (OR=4.36; 95% CI: 1.93-9.84) and among people who have not had an AIDS test. CONCLUSION: Knowledge of preventive methods and transmission routes is good in more than half of the population of Chókwè. The majority of men and women do not use the condom when having sexual intercourse. Moreover, inequalities may be observed as a function of educational level and district socioeconomic level. Knowledge of preventive practices, mainly among socio-economically disadvantaged groups, must be improved and strategies designed to broaden access to use of condoms by everyone should be implemented.

Comparability between ICD-9 and ICD-10 for the leading causes of death in Spain.

BACKGROUND: Implementation of a new Revision of the International Classification of Diseases can create discontinuity in mortality statistics. Revisions are nevertheless essential to ensure international comparability of health statistics. The purpose of this work was to describe the effects of the 10th Revision on mortality statistics by sex and age for leading causes of death in Spain. METHODS: A cross-sectional study of leading causes of death was carried out when the underlying cause of death was coded using both the 9th and 10th Revisions of the International Classification of Diseases in 88,044 death certificates completed in five Autonomous Communities of Spain (Andalusia, Cantabria, Murcia, Navarra, the Basque Country), and the city of Barcelona during the year 1999. Changes introduced by the 10th Revision were described by simple correspondence, percentage of change, Kappa index and comparability ratios between the 10th and the 9th Revision along with their 95% confidence intervals by sex and five-year age group, for the leading causes of death. RESULTS: Under the 10th Revision, AIDS deaths rose by 3.6% (comparability ratio (CR): 1.036; 95% confidence interval (CI):1.015-1.058), arteriosclerosis by 7.1% (CR: 1.071; 95% CI: 1.052-1.090), and drug overdose by 5.2% (CR: 1.052; 95% CI: 0.964-1.140). Mortality due to vascular and senile dementia and non specific dementia declined by 3.2% under the 10th (CR: 0.969; 95% CI: 0.950-0.988). In all the other causes of death the percentage of change regardless of direction was less than 2%. CONCLUSION: The present study found good agreement between ICD-9 and ICD-10 on the leading causes of death and premature mortality in Spain. Causes of death which present differences between Revisions were AIDS, arteriosclerosis, drug overdose and senile dementia. For these causes, the comparability ratios must be taken into account when interpreting mortality statistics.

Socioeconomic status and ischaemic heart disease mortality in 10 western European populations during the 1990s.

OBJECTIVE: To assess the association between socioeconomic status and ischaemic heart disease (IHD) mortality in 10 western European populations during the 1990s. DESIGN: Longitudinal study. SETTING: 10 European populations (95,009,822 person years). METHODS: Longitudinal data on IHD mortality by educational level were obtained from registries in Finland, Norway, Denmark, England/Wales, Belgium, Switzerland, Austria, Turin (Italy), Barcelona (Spain), and Madrid (Spain). Age standardised rates and rate ratios (RRs) of IHD mortality by educational level were calculated by using Poisson regression. RESULTS: IHD mortality was higher in those with a lower socioeconomic status than in those with a higher socioeconomic status among men aged 30-59 (RR 1.55, 95% confidence interval (CI) 1.51 to 1.60) and 60 years and over (RR 1.22, 95% CI 1.21 to 1.24), and among women aged 30-59 (RR 2.13, 95% CI 1.98 to 2.29) and 60 years and over (RR 1.36, 95% CI 1.33 to 1.38). Socioeconomic disparities in IHD mortality were larger in the Scandinavian countries and England/Wales, of moderate size in Belgium, Switzerland, and Austria, and smaller in southern European populations among men and younger women (p < 0.0001). For elderly women the north-south gradient was smaller and there was less variation between populations. No socioeconomic disparities in IHD mortality existed among elderly men in southern Europe. CONCLUSIONS: Socioeconomic disparities in IHD mortality were larger in northern than in southern European populations during the 1990s. This partly reflects the pattern of socioeconomic disparities in cardiovascular risk factors in Europe. Population wide strategies to reduce risk factor prevalence combined with interventions targeted at the lower socioeconomic groups can contribute to reduce IHD mortality in Europe.

Socioeconomic differences in the prevalence of common chronic diseases: an overview of eight European countries.

BACKGROUND: Few studies have compared socioeconomic inequalities in the prevalence of both fatal and non-fatal diseases. This paper aims to give the first international overview for several common chronic diseases. METHODS: Micro-level data were pooled from non-standardized national health surveys conducted in eight European countries in the 1990s. Surveys ranged in size from 3700 to 41 200 participants. The prevalence of 17 chronic disease groups were analysed in relation to education. Standardized prevalence rates and age-adjusted odds ratios (ORs) were calculated. RESULTS: Most diseases showed higher prevalence among the lower education group. Stroke, diseases of the nervous system, diabetes, and arthritis displayed relatively large inequalities (OR > 1.50). No socioeconomic differences were evident for cancer, kidney diseases, and skin diseases. Allergy was more common in the higher education group. Relative socioeconomic differences were often smaller among the 60-79 age group as compared with the 25-59 age group. Cancer was more prevalent among the lower educated in the 25-59 age group, but among the higher educated in the 60-79 age group. For diabetes, hypertension, and heart disease, socioeconomic differences were larger among women as compared with men. Inequalities in heart disease were larger in northern European countries as compared with southern European countries. CONCLUSION: There are large variations between chronic diseases in the size and pattern of socioeconomic differences in their prevalence. The large inequalities that are found for some specific fatal diseases (e.g. stroke) and non-fatal diseases (e.g. arthritis) require special attention in equity-oriented research and policies.

Education level inequalities and transportation injury mortality in the middle aged and elderly in European settings.

OBJECTIVE: To study the differential distribution of transportation injury mortality by educational level in nine European settings, among people older than 30 years, during the 1990s. METHODS: Deaths of men and women older than 30 years from transportation injuries were studied. Rate differences and rate ratios (RR) between high and low educational level rates were obtained. RESULTS: Among men, those of low educational level had higher death rates in all settings, a pattern that was maintained in the different settings; no inequalities were found among women. Among men, in all the settings, the RR was higher in the 30-49 age group (RR 1.46, 95% CI 1.32 to 1.61) than in the age groups 50-69 and > or = 70 years, a pattern that was maintained in the different settings. For women for all the settings together, no differences were found among educational levels in the three age groups. In the different settings, only three had a high RR in the youngest age group, Finland (RR 1.33, 95% CI 1.01 to 1.74), Belgium (RR 1.38; 95% CI 1.13 to 1.67), and Austria (RR 1.49, 95% CI 0.75 to 2.96). CONCLUSION: This study provides new evidence on the importance of socioeconomic inequalities in transportation injury mortality across Europe. This applies to men, but not to women. Greater attention should be placed on opportunities to select intervention strategies tailored to tackle socioeconomic inequalities in transportation injuries.

Trends in smoking behaviour between 1985 and 2000 in nine European countries by education.

OBJECTIVE: To examine whether trends in smoking behaviour in Western Europe between 1985 and 2000 differed by education group. DESIGN: Data of smoking behaviour and education level were obtained from national cross sectional surveys conducted between 1985 and 2000 (a period characterised by intense tobacco control policies) and analysed for countries combined and each country separately. Annual trends in smoking prevalence and the quantity of cigarettes consumed by smokers were summarised for each education level. Education inequalities in smoking were examined at four time points. SETTING: Data were obtained from nine European countries: Norway, Sweden, Denmark, Finland, the United Kingdom, the Netherlands, Germany, Italy, and Spain. PARTICIPANTS: 451 386 non-institutionalised men and women 25-79 years old. MAIN OUTCOME MEASURES: Smoking status, daily quantity of cigarettes consumed by smokers. RESULTS: Combined country analyses showed greater declines in smoking and tobacco consumption among tertiary educated men and women compared with their less educated counterparts. In country specific analyses, elementary educated British men and women, and elementary educated Italian men showed greater declines in smoking than their more educated counterparts. Among Swedish, Finnish, Danish, German, Italian, and Spanish women, greater declines were seen among more educated groups. CONCLUSIONS: Widening education inequalities in smoking related diseases may be seen in several European countries in the future. More insight into effective strategies specifically targeting the smoking behaviour of low educated groups may be gained from examining the tobacco control policies of the UK and Italy over this period.

[Changes in tobacco use in the general population of Barcelona, 1983-2000].

OBJECTIVES: To analyze the prevalence trends for smoking and its determinants in the general population of Barcelona from 1983 to 2000. DESIGN: Time series study. SETTING: Health survey based on home interviews of a representative sample of the general population of Barcelona. PARTICIPANTS: In the years 1983, 1992, and 2000 we interviewed 3134, 5004, and 10,000 persons, respectively. MAIN OUTCOME MEASURES AND RESULTS: Between 1983 and 2000 daily tobacco use showed a steady tendency to decrease among men, with a prevalence that decreased from 54.6% to 38.3%, while in women, smoking increased between 1983 and 1992 (from 20.9% to 25.4%) but remained stable in 2000 (24.5%). The proportion of smokers who said they wanted to quit increased in both sexes from 1992 (54.2%) to 2000 (65.7%). During this period the proportion of smokers who said their doctor had advised them to quit increased from 36.1% to 48.1%. The trends for both sexes showed that consumption of tobacco products was greater among less privileged socioeconomic groups. CONCLUSIONS: The results of this study confirm the decrease in the prevalence of daily consumption of tobacco products and the increase in smokers who would like to quit, in parallel with the increase in advice from physicians to quit. However, the trends among younger groups remained stable, a finding that makes it necessary to intensify efforts aimed at this population group.

[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).

[Exposure to smoking during pregnancy: Barcelona (Spain) 1994-2001].

BACKGROUND: Exposure to smoking during pregnancy is an important risk factor for child health. In the last few decades, the prevalence of smoking among fertile women has increased in Spain. OBJECTIVES: To assess fetal exposure to smoking in a representative sample of pregnant women and its trends. METHODS: The prevalence of smoking and smoking cessation were analyzed in a representative sample of women who gave birth in the city of Barcelona, extracted from a population-based registry of birth defects. The sample consisted of 1,801 women and covered the period 1994 to 2001. RESULTS: Among pregnant women, 43.4 % smoked before pregnancy, and 42.2 % of these quit. At the time of giving birth, 25.2 % of the women were smokers. Over the period studied the prevalence of smoking among pregnant women clearly decreased. Although the proportion of cessations showed no significant changes, fetal exposure to tobacco decreased. CONCLUSIONS: The prevalence of smoking among pregnant women was high, although many quit during pregnancy. Over the period studied, fetal exposure to smoking decreased. There is a need for more systematic interventions.

Socioeconomic inequalities in mortality among elderly people in 11 European populations.

STUDY OBJECTIVE: To describe mortality inequalities related to education and housing tenure in 11 European populations and to describe the age pattern of relative and absolute socioeconomic inequalities in mortality in the elderly European population. DESIGN AND METHODS: Data from mortality registries linked with population census data of 11 countries and regions of Europe were acquired for the beginning of the 1990s. Indicators of socioeconomic status were educational level and housing tenure. The study determined mortality rate ratios, relative indices of inequality (RII), and mortality rate differences. The age range was 30 to 90+ years. Analyses were performed on the pooled European data, including all populations, and on the data of populations separately. Data were included from Finland, Norway, Denmark, England and Wales, Belgium, France, Austria, Switzerland, Barcelona, Madrid, and Turin. MAIN RESULTS: In Europe (populations pooled) relative inequalities in mortality decreased with increasing age, but persisted. Absolute educational mortality differences increased until the ages 90+. In some of the populations, relative inequalities among older women were as large as those among middle aged women. The decline of relative educational inequalities was largest in Norway (men and women) and Austria (men). Relative educational inequalities did not decrease, or hardly decreased with age in England and Wales (men), Belgium, Switzerland, Austria, and Turin (women). CONCLUSIONS: Socioeconomic inequalities in mortality among older men and women were found to persist in each country, sometimes of similar magnitude as those among the middle aged. Mortality inequalities among older populations are an important public health problem in Europe.

The geography of the highest mortality areas in Spain: a striking cluster in the southwestern region of the country.

AIMS: To determine the areas of Spain with the most increased mortality risk. METHODS: Age adjusted relative risk of death by gender was estimated in each of 2218 small areas of the country using a non-parametric empirical Bayes method. To determine areas with "significantly increased risk" a Poisson based score test was used. RESULTS: Mapping of the highest risk areas showed a striking geographical clustering in the southwestern region of the country. This region, comprising 8% of the Spanish population, accounts for about one third (2884 deaths) of the total excess mortality.

Social inequalities in perinatal mortality in a Southern European city.

The objective of this study was to describe and explain inequalities in perinatal mortality by educational level and occupational social class in Barcelona for the years 1993-1997. This was a case-control study. Cases were singleton perinatal deaths, controls were singleton live births obtained from a 2% random sample of births. The association among educational level, social class, other confounding and explanatory variables and perinatal mortality was studied through crude and adjusted odds ratios (OR) obtained by logistic regression. The study comprised 423 cases and 1032 controls. The model with mother's age and educational level showed that women with primary education had an OR of 1.75 (95% CI: 1.26-2.42), this association disappearing when explanatory variables were included. We also found inequalities by educational level in fetal mortality. These results point out the need to improve the living conditions, behavioural factors and also the management of pregnancy, labour and the health care of the newborn of these mothers with greater risk.

Role of individual and contextual effects in injury mortality: new evidence from small area analysis.

OBJECTIVE: To analyse the role of individual and contextual variables in injury mortality inequalities from a small area analysis perspective, looking at the data for the city of Barcelona (Spain) for 1992-98. SETTING: Barcelona (Spain). METHODS: All injury deaths in residents older than 19, which occurred in the period 1992-98 were included (n=4393). Age and sex specific mortality rates were calculated for each educational level and each cause of death (traffic injuries, falls, drug overdose, suicide, other injuries). The contextual variables included were the proportion of men unemployed, and the proportion of men in jail, in each neighbourhood. Multilevel Poisson regression models were fitted using data grouped by age, educational level, and neighbourhood for each sex. RESULTS: Death rates were higher in males, at the extremes of the age distribution (under 44 and over 74 years), and for lower educational levels. The results of the Poisson multilevel models indicate that inequalities by educational level follow a gradient, with higher risks for the population with no schooling, after having adjusted for the contextual variables of the neighbourhood. Such inequalities were more important in the youngest age group (20-34 years), as relative risk of 5.41 (95% confidence interval (CI) 3.9 to 7.4) for all injury causes in males and 4.38 (95% CI 2.3 to 8.4) in females. The highest relative risks were found for drug overdose. There was a contextual neighbourhood effect (the higher the deprivation, the higher the mortality) after having taken into account individual variables. CONCLUSION: The findings underscore the need to implement injury prevention strategies not only at the individual level taking into account socioeconomic position, but also at the neighbourhood level.

[Lung cancer mortality in Barcelona: evidence for an initial decline in men].

BACKGROUND: Tobacco use in Spain is still high, with many smoking related deaths. However, a decrease in smoking prevalence in men has been observed in recent years, with a stabilisation or an increase among women. This paper studies the evolution of cancer mortality in Barcelona city (Catalonia, Spain) according to age and sex over the period 1984-1998. SUBJECTS AND METHOD: The evolution of annual mortality by age and sex was calculated. Specific mortality rates were estimated by age and sex strata; crude and standardized death rates for each year were also determined. Finally, for the 35-64 years population, specific mortality rates were estimated for each 5-year period (1984-1988, 1989-1993, and 1994-1998). RESULTS: Mortality rates do not change for men aged 35-39, 50-54 and 55-59 years. There was a decrease in lung cancer mortality rates in the 1994-1998 period compared to the first period for those men in the 60-64 years group. In men in the 40-44 and 45-49 years groups, rates increased in the second and stabilize in the last period. Global rates in men in the 35-64 years group, both crude and adjusted, were in the first and last 5-year periods. Among women, rates are much lower, although there was a significant increase in the 35-39 and 45-49 years groups. Crude and adjusted rates in all women aged 35 to 64 years displayed an increase in the last 5-year period. CONCLUSIONS: These results show that in Barcelona the decrease in smoking prevalence among males is now leading to an initial decrease in lung cancer mortality. The turning point seems to be in the period 1989-1993. On the contrary, there is a clear increase among young women, although the rates are still much lower.

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.
