Fatores associados à realização dos exames de rastreamento para o câncer de próstata: um estudo de base populacional

Access to general health care among people with disabilities in Latin America and the Caribbean: a systematic review of quantitative research

In Latin America and the Caribbean (LAC), there are 85 million people with disabilities (PwD). They often experience barriers accessing healthcare and die, on average, 10-20 years earlier than those without disabilities. This study aimed to systematically review the quantitative literature on access to general healthcare among PwD, compared to those without disabilities, in LAC. A systematic review and narrative synthesis was conducted. We searched in EMBASE, MEDLINE, LILACS, MedCarib, PsycINFO, SciELO, CINAHL, and Web of Science. Eligible articles were peer-reviewed, published between January 2000 and April 2023, and compared healthcare access (utilization, coverage, quality, affordability) between PwD and without disabilities in LAC. The search retrieved 16,538 records and 30 studies were included, most of which had a medium or high risk of bias (n = 23; 76%). Overall, the studies indicated that PwD use healthcare services more than those without disabilities. Some evidence indicated that women with disabilities were less likely to have received cancer screening. Limited evidence showed that health services affordability and quality were lower among PwD. In LAC, PwD appear to experience health inequities, although large gaps exist in the current evidence. Harmonization of disability and health access data collection is urgently needed to address this issue.

Social inequalities in access to cancer screening and early detection: A population-based study in the city of São Paulo, Brazil

OBJECTIVE

This study monitors trends in access to cancer screening, focusing on mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA), assessing the magnitude of inequality in the city of São Paulo from 2003 to 2015 according to education level.

METHOD

This is a cross-sectional population-based study conducted with data from the 2003, 2008, and 2015 editions of the Health Survey of the City of São Paulo (ISA-Capital). Outcome variables were the proportion of mammography, Papanicolaou (Pap smear), and Prostate-Specific Antigen (PSA) tests according to the protocols. Inequality was measured by education level according to years of study. For static analysis, Poisson regression was used to estimate proportion ratios.

RESULTS

The proportion of Pap smears remained stationary at a high level (>89%) throughout the study period, while access to mammography and PSA tests significantly increased in the 2003‒2015 period. The present results indicate inequalities in access to cancer screening due to education, and being more expressive for mammography and PSA tests. However, this inequality significantly decreased over the period analyzed comparing the most educated individuals with those with the lowest educational level. In addition, an increase in the proportion of tests performed in the Brazilian Unified Health System was identified, especially for mammography and PSA tests, in the period 2003‒2015.

CONCLUSIONS

The inequalities observed in the access to preventive exams were influenced by the level of education. The offer of exams was expanded, more significantly for mammography and PSA, especially among the less educated group.

Brazilian Survey on Preventive Actions for the Population With Access to Primary Healthcare: Inefficient Spending in a Country in Economic Crisis

BACKGROUND

Cancer ranks second as a cause of death in Brazil. Although preventive practices are part of the daily routine of primary healthcare (PHC) teams, organized screening programs are lacking. This study aimed to evaluate the adequacy of preventive interventions in the main cancer types, as defined by the Brazilian government.

METHODS

We analyzed cross-sectional data from a larger project conducted in 2016 with PHC service users and physicians from all over Brazil, interviewed by trained research staff. The sample was stratified by the number of PHC physicians per geographic region, who were eligible for inclusion if they had been working in the same PHC unit for at least one year. Twelve adult patients with at least two encounters were included per participating physician. Only the data from service users were analyzed in this study. We evaluated the questions about preventive practices and calculated the following indicators: coverage, focus, screening errors, and screening ratio. National guidelines and international evidence were used as a comparison parameter.

RESULTS

The study population consisted of 6160 service users. The data indicate that the recommendations for cervical, breast, and prostate cancer screening and for treatment of tobacco dependence are not adequately followed. Coverage for breast and cervical cancer screening presented an overutilization bias, with rates 50% and 9% above the expected, respectively. The screening focus was also inadequate: 24%, 47%, and 54% of the screening tests for the three cancer types were performed in individuals outside the recommended age range. 31% of smokers were not approached for treatment.

CONCLUSION

These findings indicate that the Brazilian population has been subjected to inadequate and potentially iatrogenic interventions in PHC. New policies based on stricter criteria of adequacy and increased use of the concept of quaternary prevention may improve the effectiveness and equity of the health system.

Prostate examination among adult and elderly subjects in southern Brazil: a cross-sectional population-based study

BACKGROUND

Population-wide screening for prostate cancer remains a controversial topic, given the need for an individualized approach to patients regarding the risks and benefits of prostate-specific antigen testing and digital rectal examination.

OBJECTIVE

The aim of this study was to investigate the prevalence of, and factors associated with, prostate examination among men aged 45 or older.

DESIGN AND SETTING

Cross-sectional population-based study developed in the city of Rio Grande (RS), Brazil.

METHODS

The outcome of interest was a history of prostate examination (prostate-specific antigen testing or digital rectal examination). The following independent variables were analyzed: age group, skin color, marital status, schooling, economic level, leisure-time physical activity, smoking habits, excessive alcohol consumption, overweight, health insurance, visits to the doctor during the preceding year, hypertension and diabetes. After a two-stage sampling process, the final sample consisted of 281 male individuals.

RESULTS

The prevalence of a history of prostate-specific antigen testing or digital rectal examination was 68.3% (95% confidence interval (CI): 62.2 to 74.5). The highest prevalence rates were observed among men aged 70 years or older (88%) and the lowest among smokers (36%). The following characteristics were found to be associated with the outcome: advanced age; marital status other than single; more schooling and higher economic status; practicing physical activity; non-smoking habits; overweight; having health insurance; and having visited a doctor during the preceding year.

CONCLUSION

Approximately two thirds of the study population had been screened for prostate examination, mostly older individuals, with higher socioeconomic status and a healthier lifestyle.

["Affected by the touch": Meanings attributed to prostate cancer prevention practices among men]

The aim of this study was to identify and analyze meanings attributed to practices related to prostate cancer prevention among men. A qualitative methodology was employed, with semi-structured interviews being conducted with 21 men in the city of Vitoria da Conquista, Bahia, between July and August of 2017. Data analysis was based on a dialectical hermeneutic approach. We found that practices related to prostate cancer prevention were based on scarce information and permeated by a sense of fear of the disease, which was thought of as a death sentence. Additionally, these feelings were compounded by the repercussions of rectal examination, perceived as a violation of one's masculinity. We were able to observe that practices devised to prevent prostate cancer reflect the repercussions of conceptions of masculinity regarding men's health care, where manliness and toughness can be susceptible by the touch.

Digital rectal examination and its associated factors in the early detection of prostate cancer: a cross-sectional population-based study

BACKGROUND

Digital rectal examination (DRE) is one of the most common strategies for prostate cancer early detection. However, the use for screening purposes has a controversial benefit and potential harms can occur due to false-positive results, overdiagnosis and overtreatment. The objective of this study is to calculate the prevalence and identify factors associated with the receipt of DRE in Brazilian men.

METHODS

We selected men older than 40 from a nationwide population-based survey (13,625 individuals) excluding those with prostate cancer diagnosis. Information was extracted from the most recent database of the Brazilian National Health Survey (PNS 2013). Statistical analysis was carried out to calculate incidence rate ratios, with 95% confidence intervals and p values, through multivariate analysis with Poisson regression and robust variance.

RESULTS

Men having private health insurance (63.3%; CI = 60.5-66.0) presented higher prevalence of DRE than those in the public health system (41.6%; CI = 39.8-43.4). The results show a positive association between DRE and men having private health insurance, aged 60-69, living with a spouse, never smokers, and living in urban areas. Among public health services users, this positive association was observed among men aged 70-79, living with a spouse, having bad/very bad health self-perception, abstainers, ex-smokers, with undergraduate studies, presenting four or more comorbidities, and residing in urban areas.

CONCLUSIONS

Prostate cancer screening with DRE is quite frequent in Brazil, specially among men with private health plans and better access to health services, healthier lifestyle and at more advanced ages, characteristics which increase the risk of overdiagnosis and overtreatment.

Future burden of prostate cancer mortality in Brazil: a population-based study

Prostate cancer mortality projections at the nationwide and regional levels to the year 2025 are carried out in this ecological study that is based on an analysis of Brazilian trends between 1996 and 2010. The predictions were made for the period 2011-2025 utilizing the Nordpred program based on the period of 1996-2010, using the age-period-cohort model. A significant increase was observed in the Brazilian rates between 1996 and 2006, followed by a non-significant decrease. The projections indicate a decrease in rates at a national level as well as for the Central, South and Southeast regions. Increases are expected for the North and Northeast regions. In conclusion, a reduction in the mortality rates for prostate cancer in Brazil is expected to the year 2025, as well as for the Central, South and Southeast regions. However, an increase in the absolute number of deaths in all regions is expected due to the anticipated aging of the population.

Prevalência e fatores associados à realização de exames de rastreamento para câncer de próstata em idosos de Juiz de Fora, MG, Brasil

Pouco se conhece sobre as práticas de rastreamento para câncer de próstata em idosos brasileiros. O objetivo deste estudo foi estimar a prevalência de realização de exames de rastreamento para câncer de próstata em idosos de Juiz de Fora (MG) e analisar os fatores associados. Trata-se de estudo seccional com 2825 homens de 60 anos ou mais que participaram da campanha de vacinação contra gripe de 2006. Foram analisadas variáveis sociodemográficas e relativas a condições de saúde e ao uso de serviços de saúde. Utilizou-se a regressão de Poisson na análise multivariada para avaliar associações entre as covariáveis e as variáveis dependentes e estimou-se a prevalência de realização dos exames. A idade média da população foi de 70,0 (± 7,2) anos. A prevalência de realização de toque retal foi 61,0% e a de PSA 75,5%. As variáveis "história familiar de câncer de próstata", "tipo de serviço de saúde", "status conjugal", "uso de medicação regular" e "escolaridade" foram fatores independentes associados à realização de toque retal. As mesmas variáveis, com exceção do "status conjugal", permaneceram no modelo múltiplo para PSA. O estudo evidencia que muitos idosos têm aderido à prática do rastreamento e a necessidade de dimensionar e qualificar esse processo, tendo em vista suas possíveis repercussões na saúde pública.

Persons with disabilities, cancer screening and related factors

The scope of this article is to describe persons with disabilities (PwD) being subjected to cancer screening and the relationship between some social variables and inequalities in performing these tests. A cross-sectional study of cancer screening among PwD was conducted in 2007 with 333 participants interviewed in residence in 4 cities of São Paulo. Variables in the practice of cancer screening, disabilities, gender, age, income of main family breadwinner, ethnicity, use of health services, assistance required, private health insurance, and coverage by the family health program were studied. Frequencies, χ²-test, trend χ² percentages and the Odds Ratios (OR) were used for data analysis. 44% of PwD attended at least one cancer screening at the appropriate time. Persons with visual disabilities and with hearing disabilities were subjected to more screening examinations than those with mobility disabilities and women were attended in screening exams more than men. Persons between the ages of 21 and 60 reported cancer screening more frequently than those between 80 and 97 years of age. The outcomes indicate that PwD have different attitudes toward cancer screening according to the type of disability, gender, and age, which were the variables that directly influenced cancer screening exams.

High incidence of prostate cancer metastasis in Afro-Brazilian men with low educational levels: a retrospective observational study

BACKGROUND

This study investigated factors related to ethnicity and educational level, their correlation with tumor stage at the time of diagnosis, and their influence on treatment outcomes in patients with prostate cancer.

METHODS

In this retrospective observational study, we analyzed the medical records of 1,349 male patients treated for prostatic adenocarcinoma. We collected information about sociodemographic variables, including educational level and self-reported skin color. We also classified the disease according whether it was to more likely to present with metastasis and measured the tumor response to treatment.

RESULTS

Less-educated (<8 years of education) individuals were 4.8 times more likely to develop metastasis than those with more education (>11 years of education; p < 0.001). Similarly, patients with a self-reported black skin color had a 300% increased risk of metastasis at diagnosis (p = 0.001). Distant metastasis was independently correlated with worse outcomes, such that individuals with distant metastasis were 10 times more likely to die than were those without distant metastasis.

CONCLUSIONS

Patients with self-reported black skin color and <8 years of education were more likely to display advanced disease at the time of diagnosis compared with their counterparts. Only the presence of metastasis was independently associated with mortality or progressive disease.

[Men's health policy]

The paper discusses the articulation among epidemiological information systems, scientific production and men's health policies. Three secondary sources were used: data from the Ministry of Health (Mortality and Hospital Information Systems, Surveillance of Protection and Risk Factors for Chronic Diseases through Telephone Survey), papers published in SciELO, and documents of the Ministry of Health regarding men's health. The results indicate that, in terms of morbidity and mortality, men are more exposed to risks than women. In the scientific production, studies focus predominantly on injuries and diseases that affect exclusively the male population, to the detriment of other health-related aspects. Legal documents highlight the epidemiological panorama of male morbidity and mortality and the policy-making methodology. Researchers need to expand the use of data from the epidemiological information systems of the Ministry of Health and to incorporate the gender relational perspective critically.

Mortality among adults: gender and socioeconomic differences in a Brazilian city

Background

Population groups living in deprived areas are more exposed to several risk factors for diseases and injuries and die prematurely when compared with their better-off counterparts. The strength and patterning of the relationships between socioeconomic status and mortality differ depending on age, gender, and diseases or injuries. The objective of this study was to identify the magnitude of social differences in mortality among adult residents in a city of one million people in Southeastern Brazil in 2004-2008.

Methods

Forty-nine health care unit areas were classified into three homogeneous strata using 2000 Census small-area socioeconomic indicators. Mortality rates by age group, sex, and cause of death were calculated for each socioeconomic stratum. Mortality rate ratios (RR) and 95% confidence intervals were estimated for the low and middle socioeconomic strata compared with the high stratum.

Results

In general, age-specific mortality rates showed a social gradient of increasing risks of death with decreasing socioeconomic status. The highest mortality rate ratios between low and high strata were observed in the 30-39 age group for males (RR = 1.74, 95% CI 1.59-1.89), and females (RR = 1.90, 95% CI 1.65-2.15). Concerning specific diseases and injuries, the greatest inequalities between low and high strata were found for homicides (RR = 2.44, 95% CI 2.27-2.61) and traffic accidents (RR = 1.64, 95% CI 1.45-1.83) among males. For women, the highest inequalities between the low and high strata were for chronic respiratory diseases (RR = 2.19, 95% CI 1.94-2.45) and acute myocardial infarction (RR = 1.93, 95% CI 1.79-2.07). Only breast cancer showed a reversed social gradient (RR = 0.70, 95% CI 0.48-0.92). Inequalities in circulatory and respiratory diseases mortality were greater among females than among males.

Conclusions

Substandard living conditions are related to unhealthy behaviors, as well as difficulties in accessing health care. Therefore, the Brazilian Health System (SUS) must ensure greater access to primary and hospital care, and develop programs that promote healthier lifestyles among vulnerable groups to reduce social inequalities in mortality. Moreover, because deaths from external causes are concentrated in poor areas, cooperative and coordinated intersectoral actions should be taken to combat the deadly violence cycle.
