Social class and cancer survival in Turin, Italy

Cancer mortality associated with low education in Italy

BACKGROUND

This study provides a nationwide representative quantification of the impact of educational inequalities on cancer mortality in Italy.

METHODS

The study is based on prevalence data and mortality rate ratios according to levels of education obtained from the Italian 2011 census cohort, including >35 million individuals aged 30-74. We estimated the population attributable fraction (PAF) and the number of cancer deaths associated with low education (below university degree) in Italy by sex.

RESULTS

PAFs for low levels of education were 29.1% among men and 13.3% among women, corresponding to 22,271 cancer deaths associated with low education in men and 7456 in women in 2019. PAFs by cancer site in men were: 53.0% for upper aerodigestive tract (UADT), 44.6% for liver, 41.3% for stomach, 41.3% for lung, 37.0% for bladder, 18.5% for colorectal, 9.8% for prostate and 9.1% for pancreatic cancers. PAFs in women were: 44.5% for cervical, 36.1% for UADT, 34.9% for stomach and 13.9% for colorectal cancers. The cancer sites with the highest number of deaths associated with low education were lung among men (7902/22,271, 35.5%) and colorectum among women (780/7456, 10.5%).

CONCLUSIONS

About a quarter of cancer deaths in 2019 in Italy may be prevented by reducing the socioeconomic determinants that contribute to educational disparities in cancer mortality.

Geographically Derived Socioeconomic Factors to Improve Risk Prediction in Patients Having Aortic Valve Replacement

Socioeconomic status (SES) has been associated with adverse outcomes after cardiac surgery, but is not included in commonly applied risk adjustment models. This study evaluates whether inclusion of SES improves aortic valve replacement (AVR) risk prediction models, as this is the most common elective operation performed at our institution during the study period. All patients who underwent AVR at a single institution from 2005 to 2015 were evaluated. SES measures included unemployment, poverty, household income, home value, educational attainment, housing density, and a validated SES index score. The risk scores for mortality, complications, and increased length of stay were generated using models published by the Society for Thoracic Surgeons. Univariate models were fitted for each SES covariate and multivariable models for mortality, any complication, and prolonged length of stay (PLOS). A total of 1,386 patients underwent AVR with a 2.7% mortality, 15.1% complication rate, and 9.7% PLOS. In univariate models, higher education was associated with decreased mortality (odds ratio [OR] 0.96, p = 0.04) and complications (OR 0.97, p <0.01). Poverty was associated with increased length of stay (OR 1.02, p = 0.02). In the multivariable models, the inclusion of SES covariates increased the area under the curve for mortality (0.735 to 0.750, p = 0.14), for any complications (0.663 to 0.680, p <0.01), and for PLOS (0.749 to 0.751, p = 0.12). The inclusion of census-tract-level socioeconomic factors into the the Society of Thoracic Surgeons risk predication models is new and shows potential to improve risk prediction for outcomes after cardiac surgery. With the possibility of reimbursement and institutional ranking based on these outcomes, this study represents an improvement in risk prediction model.

Education predicts cervical cancer survival: a Lithuanian cohort study

Background

: We examined inequalities in cervical cancer survival in Lithuania by education and place of residence. : The study is based on the linked dataset that includes all records of the 2001 population Census, all records from Lithuanian Cancer Registry (cancer incidence) and all death and emigration records from Statistics Lithuania for the period between 6 April 2001 and 31 December 2009. The study group includes cervical cancers registered in the Cancer Registry from 1 January 2002 to 31 December 2006. Analysis was restricted to women who were 25-64 years old at the Census date (in total 1 866 cases). : During the study period there were 671 deaths corresponding to an overall 5-year survival proportion 64.13% (95% CI 61.86-66.31). Place of residence and education of cervical cancer patients had strong impact on survival; 5-year survival was higher in women living in urban areas than in rural (68.61 and 55.93%) and survival decreased with decreasing education: from 79.77% in highest education group to 64.85 and 50.48% in groups with secondary and lower than secondary education. The effect of place of residence declined when stage of disease was included in the model and became not significant in final model with education adjustment. The effect of education declined after inclusion of stage and other variables, however, remained significant. : We found that women with higher education experienced higher survival following a cervical cancer diagnosis, and stage of disease at the time of diagnosis explains only the part of observed differences.

Absence of socioeconomic inequalities in access to good-quality breast cancer treatment within a population-wide screening programme in Turin (Italy)

Several studies suggest that population-based breast cancer screening programmes might help reduce social inequalities in breast cancer survival both by increasing early diagnosis and by improving access to effective treatments. To start disentangling the two effects, we evaluated social inequalities in quality of treatment of screen-detected breast cancer in the city of Turin (Italy). Combining data from the Audit System on Quality of Breast Cancer Treatment and the Turin Longitudinal Study, we analysed 2700 cases in the screening target age class 50-69 diagnosed in the period 1995-2008. We selected 10 indicators of the pathway of care, relative to timeliness and appropriateness of diagnosis and treatment, and three indicators of socioeconomic position: education, occupational status and housing characteristics. For each indicator of care, relative risks of failure were estimated by robust Poisson regression models, controlling for calendar period of diagnosis, size of tumour and activity volume of the surgery units. The principal predictor of failure of the good care indicators was the calendar period of diagnosis, with a general improvement with time in the quality of diagnosis and treatment, followed by size of the tumour and volume of activity. Socioeconomic indicators show only a marginal independent effect on timeliness indicators. The observed associations of quality indicators with socioeconomic characteristics are lower than expected, suggesting a possible role of the screening programme in reducing disparities in the access to good-quality treatments thanks to its capability to enter screen-detected women into a protected pathway of care.

Effect of socioeconomic status on stage at diagnosis of lung cancer in a hospital-based multicenter retrospective clinical epidemiological study in China, 2005-2014

There is inconsistent evidence of associations between socioeconomic status (SES) and lung cancer stage in non-Chinese populations up to now. We set out to determine how SES affects stage at diagnosis at both individual and area levels, from a hospital-based multicenter 10-year (2005-2014) retrospective clinical epidemiological study of 7184 primary lung cancer patients in mainland China. Individual-level SES data were measured based on two indicators from case report forms of the study: an individual's education and occupation. Seven census indicator variables were used as surrogates for the area-level SES with principal component analysis (PCA). Multivariate analysis was undertaken using binary logistic regressions and multinomial logit model to describe the association and explore the effect across tertiles on stage after adjusting for demographic variables. There was a significant stepwise gradient of effect across different stages in the highest tertile of area-level SES, comparing with the lowest tertile of area-level SES (ORs, 0.77, 0.67, and 0.29 for stage II, III, and IV). Patients with higher education were less likely to have stage IV lung cancer, comparing with the illiterate group (ORs, 0.52, 0.63, 0.71, 0.64 for primary school, middle school, high school, college degree or above subgroup, respectively). Findings suggest that the most socioeconomically deprived areas may be associated with a higher risk of advanced-stage lung cancer, and increasing educational level may be correlated with a lower risk to be diagnosed at advanced stage in both men and women.

Education, survival, and avoidable deaths in Lithuanian cancer patients, 2001-2009

Background Our aim in this study is to provide a systematic assessment of the site-specific cancer survival rates of patients with different educational levels, using population-based census-linked registry data covering the entire population of Lithuania. Material and methods The study is based on the linkage between all records of the 2001 population census and all records from Lithuanian Cancer Registry (cancer incidence) and Statistics Lithuania (deaths) for the period between 6 April 2001 and 31 December 2009. Results For the vast majority of cancer sites we found an inverse gradient in survival, with the worst survival indicators in the lowest educational group. We estimated that 18.6% of the deaths in Lithuanian cancer patients could have potentially been postponed, if all the patients had the same cancer mortality as the patients with the highest educational level. Conclusion Our findings offer a warning that although the survival rates of cancer patients are improving, this progress hides disparities between different groups of patients.

Social economic inequalities and mental health II. Methodological aspects and literature review

Summary

Objective - This study provides a framework for mental health inequalities beginners. It describes the methods used to measure socio economic inequalities and the inter-relations with different aspects of mental health: residence, mental health services organisation and main diagnostic categories. Method - Literature electronic-search on Medline, Psyclit, Econlit, Social Science Index and SocioSearch usingand relating the key-words inequalities, deprivation, poverty, socio-economic status, social class, occupational class, mental health for the period 1965-2002 (June). The articles selected were integrated with manual search (publications of the same authors, cross-references, working documents and reports of international andregional organisations). Results - Inequality is not an absolute concept and, mainly, it has been changing during the last years. For example, the integration and re-definition of variables that capture, in simple indices, a complex reality; the accent on social more than on economic aspects; the geo-validity and time-reference of the inequality's indices. Moreover, the inequalities could be the result of individual preferences, in this case, the social selectionand social causation issues will raise the suitability for a public intervention. Conclusions - Up to now, research has been mainly concentrated in describing and measuring health inequalities. For designing effective interventions, policy makers need to ground decisions on health-socioeconomic inequalities explanatory models.

Inequalities in medical care utilization by South Korean cancer patients according to income: a retrospective cohort study

This study explores income inequalities in the utilization of medical care by cancer patients in South Korea, according to type of medical facilities and survival duration. The five-year retrospective cohort study used data drawn from the Korean Cancer Registry, the National Health Insurance database, and the death database of the Korean National Statistical Office. The sample consisted of 43,433 patients diagnosed with cancer in 1999. The authors found significant quantitative inequalities as a function of income in the patients' utilization of medical care. Cancer patients from the highest income class used inpatient and outpatient care more frequently than did patients from the lowest income class. Those with higher incomes tended to use more inpatient and outpatient services at major tertiary hospitals, which were known as providing better medical care than other types of hospitals and clinics. Moreover, horizontal inequality in cancer-care expenditures favoring those with higher incomes was observed during earlier periods of treatment. In conclusion, income substantially affects the utilization of inpatient and outpatient services, amount of medical expenditures, and type of medical facilities.

Education, survival and avoidable deaths in cancer patients in Finland

BACKGROUND

Relative survival after cancer in Finland is at the highest level observed in Europe and has, in general, been on a steady increase. The aim of this study is to assess whether the high survival is equally shared by different population subgroups and to estimate the possible gains that might be achieved if equity prevailed.

MATERIALS AND METHOD

The educational level and occupation before the cancer diagnosis of patients diagnosed in Finland in 1971-2005 was derived from an antecedent population census. The cancers were divided into 27 site categories. Cancer (cause)-specific 5-year survival proportions were calculated for three patient categories based on the educational level and for an occupational group of potentially health-conscious patients (physicians, nurses, teachers etc.). Proportions of avoidable deaths were derived by assuming that the patients from the two lower education categories would have the same mortality owing to cancer, as those from the highest educational category. Estimates were also made by additionally assuming that even the mortalities owing to other causes of death were all equal to those in the highest category.

RESULTS

For almost all the sites considered, survival was consistently highest for patients with the highest education and lowest for those with only basic education. The potentially health-conscious patients had an even higher survival. The differences were, in part, attributable to less favourable distributions of tumour stages in the lower education categories. In 1996-2005, 4-7% of the deaths in Finnish cancer patients could have potentially been avoided during the first 5-year period after diagnosis, if all the patients had the same cancer mortality as the patients with the highest educational background. The proportion would have also been much higher, 8-11%, if, in addition, the mortality from other causes had been the same as that in the highest educational category.

INTERPRETATION

Even in a potentially equitable society with high health care standards, marked inequalities persist in cancer survival. Earlier cancer diagnosis and the ability to cope within the health care system may be a partly relevant explanation, but personal habits and lifestyles also have a role, particularly for the cancer patients' mortality from other causes of death than cancer.

Factors affecting pattern of care and survival in a population-based cohort of non-small-cell lung cancer incident cases

OBJECTIVE

To analyze the role of sociodemographic factors as determinants of the initial pattern of care and survival in incident NSCLC cases.

METHODS

We linked 2298 incident NSCLC cases, identified by the Piedmont Cancer Registry of Turin (PCRT) with administrative health records to identify the initial pattern of care. Because stage of disease strongly influences pattern of care and prognosis of NSCLC, all the analyses were stratified according to stage (early and advanced). The association between the set of patient's characteristics and the probability of accessing a specific pattern of care was analysed with a multivariable multinomial logistic regression model. Survival was analysed with the Cox proportional hazard model.

RESULTS

In the early stage group, presence of comorbidities, older age and low educational level were all associated with a lower probability of receiving surgery. These same factors, as well as being unmarried, were associated with higher probability of receiving other non-curative care only. The effects of comorbidities and low educational level as barriers to receiving more effective patterns of care were not relevant in the advanced stage group. When controlling for initial patterns of care, in the early stage group, an age older than 75 years and being unmarried were negative prognostic factors, while survival was completely independent from educational level. Among patients with an advanced stage of disease, only comorbidities had a negative impact on survival.

CONCLUSION

Appropriate lung cancer care is affected by sociodemographic factors. Greater attention to social and health programs is recommended to improve the timeliness of diagnosis, the staging of potentially resectable patients, and to implement more comprehensive multidisciplinary evaluations of those who may benefit from curative treatments.

Socioeconomic differences in cancer survival: the Norwegian Women and Cancer Study

Background

Cancer survival has been observed to be poorer in low socioeconomic groups, but the knowledge about the underlying causal factors is limited. The purpose of this study was to examine how cancer survival varies by socioeconomic status (SES) among women in Norway, and to identify factors that explain this variation. SES was measured by years of education and gross household income, respectively.

Methods

We used data from The Norwegian Women and Cancer Study, a prospective cohort study including 91 814 women who responded to an extensive questionnaire between 1996 and 1998. A total of 3 899 incident cancer cases were diagnosed during follow-up, of whom 1 089 women died, 919 of them from cancer. Cox Proportional Hazards Model was used to calculate relative risks (RR) of mortality and 95% confidence intervals.

Results

We observed an overall negative socioeconomic gradient in cancer survival, which was most evident in the site specific analyses for survival of ovarian cancer by years of education. For colorectal cancer, mortality increased with years of education, but not with income. After adjustment for household size, marital status, disease stage, and smoking status the SES variation in cancer survival became non-significant. We found that the unequal socioeconomic distribution of smoking status prior to diagnosis contributed considerably to the poorer survival in low SES groups.

Conclusion

We found an overall negative socioeconomic gradient in cancer survival when SES is measured as years of education or gross household income. Smoking status prior to diagnosis was an important predictive factor for socioeconomic variation in survival.

Differences in mortality and incidence for major sites of cancer by education level in a Japanese population

PURPOSE

We aimed to examine the relationships between education and mortality and incidence for major sites of cancer in a Japanese population.

METHODS

Subjects were 32,883 respondents of questionnaire survey in 1978 with ages younger than 75 years. Cancer cases were ascertained through 2001, and causes of deaths were identified through 2003. Hazard ratios of deaths from cancer or developing cancers were compared among those with 9 or less, 10-12, and 13 years or more of education using Cox proportional hazard models.

RESULTS

As for cancer mortality of all sites combined, a statistically significantly decreasing trend was observed in age-adjusted models in both men and women, but no significant differences were observed in multivariate-adjusted (age, body mass index, smoking, radiation dose, and city) models. Among major cancer sites (stomach, colon/rectum, liver, lung, and female breast) examined, a significantly decreasing trend was observed for male liver cancer in a multivariate-adjusted model. As for incidence, a significantly decreasing trend was observed for cancer of all sites combined in men, and for male liver and prostate cancer and female lung cancer in a multivariate-adjusted model.

CONCLUSIONS

Educational differences in cancer incidence and mortality were generally rather small, but were significant for incidence for male all-site, male liver, prostate, and female lung cancers.

Long-term inequalities in breast cancer survival--a ten year follow-up study of patients managed within a National Health Care System (Sweden)

INTRODUCTION

Converging epidemiological evidence based on studies of different designs in a variety of populations and settings show that cancer survival tends to be poorer in low compared to high socioeconomic groups. In an extension of an earlier register-based study, we examined the influence of socioeconomic factors on long-term survival in women with a first diagnosis of invasive breast cancer in 1993 in Sweden, a country with a policy of providing equal access to health care to all at nominal cost within a National Health Care System.

MATERIAL AND METHODS

The study was based on data set generated by record linkages between the Swedish Cancer Register, Census databases and the Cause of Death Register. Four different categorical variables were used as indicators of socioeconomic standing. Cox proportional hazard regression models were used to estimate the effects of socioeconomic status on risk of death.

RESULTS

Of 4 645 eligible women with breast cancer, 1 016 had died from breast cancer at the end of follow-up on December 31, 2003. After adjustment for tumour size and age at diagnosis, risk of death was 19% lower among women belonging to a household of high compared to low socioeconomic status (HR high versus low 0.81; 95% CI: 0.67-0.97).

DISCUSSION

These findings indicate that social inequalities in breast cancer survival persist at least up to ten years after an initial diagnosis. While social gradients detected shortly after diagnosis may mainly reflect an influence of socioeconomic differences in overall health status and frailty, differentials persisting beyond five years rather point to a long-term influence of disparities in management of both primary tumours and recurrences. Further studies are needed to explore whether the present findings reflect amendable inequalities in access to state-of-the-art treatment. For all calendar periods, observed survival in the most privileged groups sets the goal for what is achievable for all breast cancer patients.

Socioeconomic inequalities in alcohol related cancer mortality among men: to what extent do they differ between Western European populations?

We aim to study socioeconomic inequalities in alcohol related cancers mortality [upper aerodigestive tract (UADT) (oral cavity, pharynx, larynx, oesophagus and liver)] in men and to investigate whether the contribution of these cancers to socioeconomic inequalities in cancer mortality differs within Western Europe. We used longitudinal mortality datasets, including causes of death. Data were collected during the 1990s among men aged 30-74 years in 13 European populations [Madrid, the Basque region, Barcelona, Turin, Switzerland (German and Latin part), France, Belgium (Walloon and Flemish part, Brussels), Norway, Sweden, Finland]. Socioeconomic status was measured using the educational level declared at the census at the beginning of the follow-up period. We conducted Poisson regression analyses and used both relative [Relative index of inequality (RII)] and absolute (mortality rates difference) measures of inequality. For UADT cancers, the RII's were above 3.5 in France, Switzerland (both parts) and Turin whereas for liver cancer they were the highest (around 2.5) in Madrid, France and Turin. The contribution of alcohol related cancer to socioeconomic inequalities in cancer mortality was 29-36% in France and the Spanish populations, 17-23% in Switzerland and Turin, and 5-15% in Belgium and the Nordic countries. We did not observe any correlation between mortality rates differences for lung and UADT cancers, confirming that the pattern found for UADT cancers is not only due to smoking. This study suggests that alcohol use substantially influences socioeconomic inequalities in male cancer mortality in France, Spain and Switzerland but not in the Nordic countries and nor in Belgium.

The association of cancer survival with four socioeconomic indicators: a longitudinal study of the older population of England and Wales 1981-2000

Background

Many studies have found socioeconomic differentials in cancer survival. Previous studies have generally demonstrated poorer cancer survival with decreasing socioeconomic status but mostly used only ecological measures of status and analytical methods estimating simple survival. This study investigate socio-economic differentials in cancer survival using four indicators of socioeconomic status; three individual and one ecological. It uses a relative survival method which gives a measure of excess mortality due to cancer.

Methods

This study uses prospective record linkage data from The Office for National Statistics Longitudinal Study for England and Wales. The participants are Longitudinal Study members, recorded at census in 1971 and 1981 and with a primary malignant cancer diagnosed at age 45 or above, between 1981 and 1997, with follow-up until end 2000. The outcome measure is relative survival/excess mortality, compared with age and sex adjusted survival of the general population. Relative survival and Poisson regression analyses are presented, giving models of relative excess mortality, adjusted for covariates.

Results

Different socioeconomic indicators detect survival differentials of varying magnitude and definition. For all cancers combined, the four indicators show similar effects. For individual cancers there are differences between indicators. Where there is an association, all indicators show poorer survival with lower socioeconomic status.

Conclusion

Cancer survival differs markedly by socio-economic status. The commonly used ecological measure, the Carstairs Index, is adequate at demonstrating socioeconomic differentials in survival for combined cancers and some individual cancers. A combination of car access and housing tenure is more sensitive than the ecological Carstairs measure at detecting socioeconomic effects on survival – confirming Carstairs effects where they occur but additionally identifying effects for other cancers. Social class is a relatively weak indicator of survival differentials.

Origins of socio-economic inequalities in cancer survival: a review

BACKGROUND

Cancer survival is known to vary by socio-economic group. A review of studies published by 1995 showed this association to be universal and resilient to the many different ways in which socio-economic status was determined. Differences were most commonly attributed to differences in stage of disease at diagnosis.

MATERIALS AND METHODS

A review of research published since 1995 examining the association of cancer survival with socio-economic variables.

RESULTS

An association between socio-economic status and cancer survival has continued to be demonstrated in the last decade of research. Stage at diagnosis and differences in treatment have been cited as the most important explanatory factors. Some research has evaluated the psychosocial elements of this association.

CONCLUSIONS

Socio-economic differences in cancer survival are now well documented. The explanatory power of stage at diagnosis, although great, should not detract from the evidence of differential treatment between social groups. Neither factor can completely explain the observed socio-economic differences in survival, however, and the importance of differences in tumour and patient factors should now be quantified.

Variation in survival after diagnosis of breast cancer in Switzerland

BACKGROUND

Survival after diagnosis of cancer is a key criterion for cancer control. Major survival differences between time periods and countries have been reported by the EUROCARE studies. We investigated whether similar differences by period and region existed in Switzerland.

METHODS

Survival of 11,376 cases of primary invasive female breast cancer diagnosed between 1988 and 1997 and registered in seven Swiss cancer registries covering a population of 3.5 million was analysed.

RESULTS

Comparing the two periods 1988-1992 and 1993-1997, age-standardized 5 year relative survival improved globally from 77% to 81%. Furthermore, multivariate analysis adjusting for age, tumour size and nodal involvement identified regional survival differences. Survival was lowest in the rural parts of German-speaking eastern Switzerland and highest in urbanised regions of the Latin- and German-speaking northwestern parts of the country.

CONCLUSIONS

This study confirms that survival differences are present even in a small and affluent, but culturally diverse, country like Switzerland, raising the issue of heterogeneity in access to care and quality of treatment.

Socio-economic factors and breast cancer survival – a population-based cohort study (Sweden)

OBJECTIVE

To assess the influence of socio-economic factors on breast cancer survival in Sweden, a country with population-based mammography screening and a uniform health care system aiming to provide care to all on equal terms.

METHODS

All women with a first diagnosis of invasive breast cancer in Sweden in 1993 were identified in the Swedish Cancer Register. Their sociodemographic characteristics were determined by record linkages to the 1970, 1980, 1985 and 1990 Census databases, and a nationwide Fertility Register. Information on tumor characteristics at diagnosis was obtained from five Swedish Regional Cancer Registers. Survival status on 31 December 1998, was assessed through follow-up in the Swedish Cause of Death Register.

RESULTS

Of totally 4645 eligible women diagnosed with breast cancer in 1993, 772 had died from breast cancer through 1998. After adjustment for tumor characteristics and age, risk of death was 37 higher among women of low compared to high socio-economic status (HR high vs. low 0.73; 95 CI: 0.54-0.99). This difference was most pronounced in women less than 50 years at diagnosis.

CONCLUSIONS

These results show that socio-economic disparities in breast cancer survival prevail even in this relatively homogenous society, offering outreach mammography and standardised treatment regimens in a tax-funded health care system.

Prevalence of human papillomavirus infection in women in Turin, Italy

Human papillomavirus (HPV) is recognised as necessary for the development of cervical cancer. An age-stratified random sample of 1013 women, aged 25-70 years, participating in the organised cervical screening programme in Turin, Italy was tested for 36 HPV types using polymerase chain reaction (PCR) with the general primers GP5+/GP6+. The overall HPV prevalence was 8.8%. High-risk types were found in 7.1% of women and multiple infections in 1.1%. HPV-16 was the most common type (32.6% of HPV-positive women). HPV prevalence (any type) was 13-14% at ages 25-39 years, 11.5% at age 40-44 years, and approximately 5% among older women. After age-adjustment, HPV prevalence was significantly increased in single vs married, (Odds Ratio (OR)=2.23; 95% Confidence Interval (CI): 1.28-3.89) and decreased in parous vs nulliparous women (OR=0.49; 95% CI: 0.31-0.78). However, the association with marital status and parity was restricted to women less than 45 years of age. In conclusion, overall, the female population of Turin showed an HPV prevalence that is intermediate compared with worldwide levels.

Unequal to the task: deprivation, health and UK general practice at the millennium

The NHS is over 50 years old, but health inequalities remain prevalent in the United Kingdom (UK). Material deprivation may be less apparent; however, social deprivation is becoming worse while the markers of socioeconomic disadvantage remain unsatisfactory. Health is an even more elusive concept; nevertheless, the evidence for an increasing association between deprivation, poor health, and early death is overwhelming. Equally unavoidable is the impact of this social degradation on UK primary care. Service industries have deserted deprived communities but, on the whole, GPs struggle on. Denied the supplementary resources they deserve they become disenchanted, too exhausted to convert incentives into rewards. Clear-headed strategic thinking from the top brass is overdue.

Coronary artery bypass graft surgery: socioeconomic inequalities in access and in 30 day mortality. A population-based study in Rome, Italy

OBJECTIVES

To evaluate whether coronary artery bypass graft (CABG) surgery is equally provided among different socioeconomic status (SES) groups in accordance with need. To estimate the association between SES and mortality occurring 30 days after CABG surgery.

DESIGN

Individual socioeconomic index assigned with respect to the characteristics of the census tract of residence (level I = highest SES; level IV = lowest SES). Comparison of age adjusted hospital admission rates of ischaemic heart disease (IHD) and CABG surgery among four SES groups. Retrospective cohort study of all patients who underwent CABG surgery during 1996-97.

SETTING

Rome (2 685 890 inhabitants) and the seven cardiac surgery units in the city.

PARTICIPANTS

All residents in Rome aged 35 years or more. A cohort of 1875 CABG patients aged 35 years or more.

MAIN OUTCOME MEASURES

Age adjusted hospitalisation rates for CABG and IHD and rate of CABG per 100 IHD hospitalisations by SES group, taking level I as the reference group. Odds ratios of 30 day mortality after CABG surgery, adjusted for age, gender, illness severity at admission, and type of hospital where CABG was performed.

RESULTS

People in the lowest SES level experienced an excess in the age adjusted IHD hospitalisation rates compared with the highest SES level (an excess of 57% among men, and of 94% among women), but the rate of CABG per 100 IHD hospitalisations was lower, among men, in the most socially disadvantaged level (8.9 CABG procedures per 100 IHD hospital admissions in level IV versus 14.1 in level I rate ratio= 0.63; 95% CI 0.44, 0.89). The most socially disadvantaged SES group experienced a higher risk of 30 day mortality after CABG surgery (8. 1%) than those in the highest SES group (4.8%); this excess in mortality was confirmed even when initial illness severity was taken into account (odds ratio= 2.89; 95% CI 1.44, 5.80).

CONCLUSIONS

The universal coverage of the National Health Service in Italy does not guarantee equitable access to CABG surgery for IHD patients. Factors related to SES are likely to influence poor prognosis after CABG surgery.

Inequality in health: socioeconomic differentials in mortality in Rome, 1990-95

STUDY OBJECTIVE

Population groups with a lower socioeconomic status (SES) have a greater risk of disease and mortality. The aim of this study was to investigate the relation between SES and mortality in the metropolitan area of Rome during the six year period 1990-1995, and to examine variations in mortality differentials between 1990-92 and 1993-95.

DESIGN

Rome has a population of approximately 2,800,000, with 6100 census tracts (CTs). During the study period, 149,002 deaths occurred among residents. The cause-specific mortality rates were compared among four socioeconomic categories defined by a socioeconomic index, derived from characteristics of the CT of residence.

MAIN RESULTS

Among men, total mortality and mortality for the major causes of death showed an inverse association with SES. Among 15-44 year old men, the strong positive association between total mortality and low SES was attributable to AIDS and overdose mortality. Among women, a positive association with lower SES was observed for stomach cancer, uterus cancer and cardiovascular disease, whereas mortality for lung and breast cancers was higher in the groups with higher SES. Comparing the periods 1990-92 and 1993-95, differences in total mortality between socioeconomic groups widened in both sexes. Increasing differences were observed for tuberculosis and lung cancer among men, and for uterus cancer, traffic accidents, and overdose mortality among women.

CONCLUSIONS

The use of an area-based indicator of SES limits the interpretations of the findings. However, despite the possible limitations, these results suggest that social class differences in mortality in Rome are increasing. Time changes in lifestyle and in the prevalence of risk behaviours may produce differences in disease incidence. Moreover, inequalities in the access to medical care and in the quality of care may contribute to an increasing differentials in mortality.

Cancer mortality by educational level in the city of Barcelona

The objective of this study was to examine the relationship between educational level and mortality from cancer in the city of Barcelona. The data were derived from a record linkage between the Barcelona Mortality Registry and the Municipal Census. The relative risks (RR) of death and 95% confidence intervals (CIs) according to level of education were derived from Poisson regression models. For all malignancies, men in the lowest educational level had a RR of death of 1.21 (95% CI 1.13-1.29) compared with men with a university degree, whereas for women a significant decreasing in risk was observed (RR 0.81; 95% CI 0.74-0.90). Among men, significant negative trends of increasing risk according to level of education were present for cancer of the mouth and pharynx (RR 1.70 for lowest vs. highest level of education), oesophagus (RR 2.14), stomach (RR 1.99), larynx (RR 2.56) and lung (RR 1.35). Among women, cervical cancer was negatively related to education (RR 2.62), whereas a positive trend was present for cancers of the colon (RR 0.76), pancreas (RR 0.59), lung (RR 0.55) and breast (RR 0.65). The present study confirms for the first time, at an individual level, the existence of socioeconomic differences in mortality for several cancer sites in Barcelona, Spain. There is a need to implement health programmes and public health policies to reduce these inequities.

Prostate cancer: how aware is the public?

OBJECTIVE

To assess the public awareness of prostate cancer and willingness to seek medical attention for urinary symptoms, and to determine associated factors.

SUBJECTS AND METHODS

A community survey was conducted using a questionnaire administered by the interviewer to 280 randomly selected Irish men aged 40-69 years.

RESULTS

A quarter of the men had not heard of prostate cancer; factors associated with having heard were nonmanual social class, living with a female partner and a history of treatment for urinary disease. Eighty per cent said they would be willing to attend a GP if they had urinary symptoms; associated factors were living with a female partner, having heard of prostate cancer and having seen a GP more than once in the preceding year. Just over half deemed attendance to be urgent/important; associated factors were having heard of prostate cancer, living with a female partner and having a relative with cancer. Having a General Medical Services card (a means-tested medical card entitling the holder to free medical services) was negatively associated. Lower social class was negatively associated with routine questioning by a GP about urinary symptoms.

CONCLUSIONS

There is a marked social-class gradient in knowledge and willingness to seek medical advice. In the absence of population screening, earlier clinical presentation with prostate cancer is essential if prognosis is to be improved; there is an evident need to improve prostate cancer awareness, particularly in the lower social classes, if this goal is to be achieved.
