Politics and health outcomes

The aim of this study was to examine the complex interactions between political traditions, policies, and public health outcomes, and to find out whether different political traditions have been associated with systematic patterns in population health over time. We analysed a number of political, economic, social, and health variables over a 50-year period, in a set of wealthy countries belonging to the Organisation for Economic Co-operation and Development (OECD). Our findings support the hypothesis that the political ideologies of governing parties affect some indicators of population health. Our analysis makes an empirical link between politics and policy, by showing that political parties with egalitarian ideologies tend to implement redistributive policies. An important finding of our research is that policies aimed at reducing social inequalities, such as welfare state and labour market policies, do seem to have a salutary effect on the selected health indicators, infant mortality and life expectancy at birth.

The Importance of the Political and the Social in Explaining Mortality Differentials among the Countries of the OECD, 1950–1998

This article analyzes (within the conceptual frame defined in the previous article) the impact of political variables such as time of government by political parties (social democratic, Christian democratic or conservative, liberal, and ex-dictatorial that have governed the OECD countries during the 1950–1998 period) and their electoral support on (1) redistributional policies in the labor market and in the welfare state; (2) the income inequalities measured by Theil and Gini indexes; and (3) health indicators, such as infant mortality and life expectancy. This analysis is carried out statistically by a bivariate and a multivariate analysis (a pooled cross-sectional study). Both analyses show that political variables play an important role in defining how public and social policies determine the levels of inequalities and affect the level of infant mortality. In general, political parties more committed to redistributional policies, such as social democratic parties, are the most successful in reducing inequalities and improving infant mortality. Less evidence exists, however, on effects on life expectancy. The article also quantifies statistically the relationship between the political and the policy variables and between these variables and the dependent variables—that is, the health indicators.

Socio-economic inequalities in breast and cervical cancer screening practices in Europe: influence of the type of screening program

BACKGROUND The aim of this study was to describe inequalities in the use of breast and cervical cancer screening services according to educational level in European countries in 2002, and to determine the influence of the type of screening program on the extent of inequality. METHODS A cross-sectional study was performed using individual-level data from the WHO World Health Survey (2002) and data regarding the implementation of cancer screening programmes. The study population consisted of women from 22 European countries, aged 25-69 years for cervical cancer screening (n =11 770) and 50-69 years for breast cancer screening (n = 4784). Dependent variables were having had a PAP smear and having had a mammography during the previous 3 years. The main independent variables were socio-economic position (SEP) and the type of screening program in the country. For each country the prevalence of screening was calculated, overall and for each level of education, and indices of relative (RII) and absolute (SII) inequality were computed by educational level. Multilevel logistic regression models were fitted. RESULTS SEP inequalities in screening were found in countries with opportunistic screening [comparing highest with lowest educational level: RII = 1.28, 95% confidence interval (CI) 1.12-1.48 for cervical cancer; and RII = 3.11, 95% CI 1.78-5.42 for breast cancer] but not in countries with nationwide population-based programmes. Inequalities were also observed in countries with regional screening programs (RII = 1.35, 95% CI 1.10-1.65 for cervical cancer; and RII = 1.58, 95% CI 1.26-1.98 for breast cancer). CONCLUSIONS Inequalities in the use of cancer screening according to SEP are higher in countries without population-based cancer screening programmes. These results highlight the potential benefits of population-based screening programmes.

Construcción de un índice de privación a partir de datos censales en grandes ciudades españolas (Proyecto MEDEA)

Objectives: a) To describe the methodology used to construct a deprivation index by census tract in cities, to identify the tracts with the least favorable socioeconomic conditions, and b) to analyze the association between this index and overall mortality. Methods: Several socioeconomic indicators (Census 2001) were defined by the census tracts of the following cities: Barcelona, Bilbao, Madrid, Seville and Valencia. The correlations with the standardized mortality ratio (1996-2003), and the dimensionality of the socioeconomic indicators were studied. Finally, the selected indicators were aggregated in an index, in which the results of the factor loadings from extraction of a factor by principal components were used as weighting values. Results: The indicators with the strongest correlations with overall mortality were those related to work, education, housing conditions and single parent homes. In the analysis of dimensionality, a first dimension appeared that contained indicators related to work (unemployment, manual and eventual workers) and education (insufficient education overall and in young people). In all the cities studied, the index created with these 5 indicators explained more than 75% of their variability. The correlations between this index and mortality generally showed higher values than those obtained with each indicator separately. Conclusions: The deprivation index proposed could be a useful instrument for health planning as it detects small areas of large cities with unfavorable socioeconomic characteristics and is associated with mortality. This index could contribute to the study of social inequalities in health in Spain.

Inequalities in health by social class dimensions in European countries of different political traditions

OBJECTIVE To compare inequalities in self-perceived health in the population older than 50 years, in 2004, using Wrights social class dimensions, in nine European countries grouped in three political traditions (Social democracy, Christian democracy and Late democracies). METHODS Cross-sectional design, including data of the Survey of Health, Ageing and Retirement in Europe (Sweden, Denmark, Austria, France, Germany, The Netherlands, Spain, Italy and Greece). The population aged from 50 to 74 years was included. Absolute and relative social class dimension inequalities in poor self-reported health and long-term illness were determined for each sex and political tradition. Relative inequalities were assessed by fitting Poisson regression models with robust variance estimators. RESULTS Absolute and relative health inequalities by social class dimensions are found in the three political traditions, but these differences are more marked in Late democracies and mainly among women. For example the prevalence ratio of poor self-perceived health comparing poorly educated women with highly educated women, was 1.75 (95% CI: 1.39-2.21) in Late democracies and 1.36 (95% CI: 1.21-1.52) in Social democracies. The prevalence differences were 24.2 and 13.7%, respectively. CONCLUSION This study is one of the first to show the impact of different political traditions on social class inequalities in health. These results emphasize the need to evaluate the impact of the implementation of public policies.

Social class inequalities in the utilization of health care and preventive services in Spain, a country with a national health system

In Spain, despite the existence of a National Health System (NHS), the utilization of some curative health services is related to social class. This study assesses (1) whether these inequalities are also observed for preventive health services and (2) the role of additional private health insurance for people of advantaged social classes. Using data from the Spanish National Health Survey of 2006, the authors analyze the relationships between social class and use of health services by means of Poisson regression models with robust variance, controlling for self-assessed health. Similar analyses were performed for waiting times for visits to a general practitioner (GP) and specialist. After controlling for self-perceived health, men and women from social classes IV-V had a higher probability of visiting the GP than other social classes, but a lower probability of visiting a specialist or dentist. No large class differences were observed in frequency of hospitalization or emergency services use, or in breast cancer screening or influenza vaccination; cervical cancer screening frequency was lower among women from social classes IV-V. The inequalities in specialist visits, dentist visits, and cervical cancer screening were larger among people with only NHS insurance than those with double health insurance. Social class differences in waiting times were observed for specialist visits, but not for GP visits. Men and women from social classes IV-V had longer waits for a specialist; this was most marked among people with only NHS insurance. Clearly, within the NHS, social class inequalities are still evident for some curative and preventive services. Further research is needed to identify the factors driving these inequalities and to tackle these factors from within the NHS. Priority areas include specialist services, dental care, and cervical cancer screening.

Analyzing differences in the magnitude of socioeconomic inequalities in self-perceived health by countries of different political tradition in Europe.

The objectives of this study are to describe, for European countries, variations among political traditions in the magnitude of inequalities in self-perceived health by educational level and to determine whether these variations change when contextual welfare state, labor market, wealth, and income inequality variables are taken into account. In this cross-sectional study, the authors look at the population aged 25 to 64 in 13 European countries. Individual data were obtained from the Health Interview Surveys of each country. Educational-level inequalities in self-perceived health exist in all countries and in all political traditions, among both women and men. When countries are grouped by political tradition, social democratic countries are found to have the lowest educational-level inequalities.

Trends in socioeconomic inequalities in cancer mortality in Barcelona: 1992–2003

BackgroundThe objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003.MethodsThe study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII) and the Slope Index of Inequalities (SII). All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003).ResultsCancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers.ConclusionThis study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

Razones para acudir a los servicios de urgencias hospitalarios. La población opina

OBJETIVO: Conocer por que las personas acuden a los servicios de urgencia hospitalarios (SUH) por problemas de salud de baja complejidad. METODO: Se realizo una investigacion cualitativa de tipo fenomenologica interaccionista. La muestra teorica pertenecia a un area urbana y otra rural de Cataluna. Se escogieron personas (n = 36) que habian acudido a los SUH o a servicios de urgencia de la atencion primaria de salud (SUAP) en el mes previo a su seleccion. Se recogieron datos en 8 grupos focales. Se realizo un analisis inductivo descriptivo-interpretativo, construyendo categorias emergentes a partir de la triangulacion. RESULTADOS: Emergieron 5 categorias: sintomas, elaboracion de autodiagnostico, percepcion de necesidad, conocimiento de la oferta y contexto global de la persona. Los sintomas generan la consideracion de perdida de salud y desencadenan la accion. La elaboracion del autodiagnostico determina la necesidad-tipo de atencion. Del contraste entre la percepcion-tipo de necesidad y el conocimiento de la oferta de los servicios, asi como de la situacion vital de la persona, surge la decision de acudir a un servicio u otro y se genera la accion. El conocimiento de la oferta de los SUH es mejor que el de los SUAP. El tiempo parece basico en la toma de decisiones. CONCLUSIONES: La elaboracion de un autodiagnostico es critica en la determinacion de la accion, pero el conocimiento de la oferta de los servicios, las experiencias previas y la situacion vital de la persona modulan el tipo de demanda.
