The burden of disease among Brazilian older adults and the challenge for health policies: results of the Global Burden of Disease Study 2017

A Decade of Change in Peritoneal Dialysis in Brazil: Challenges and Perspectives in the Public Health System

Background/Objectives: The Brazilian Constitution defines health as a universal right and a State responsibility, with the Unified Public Health System (SUS) ensuring free access to comprehensive care, including renal replacement therapies (RRTs) such as dialysis and kidney transplantation. This study aimed to analyze trends in peritoneal dialysis (PD) usage within Brazil's public health system over a 10-year period, focusing on geographic, demographic, and clinical changes. Methods: Using data from DATASUS and the Brazilian Society of Nephrology Dialysis Census, we analyzed PD usage and patient characteristics from 2014 to 2023. This methodology enabled an in-depth examination of shifts in RRT trends across regions and patient demographics. Results: PD usage declined from 6.5% in 2014 to 4.3% in 2023, with the steepest reductions observed in the North and Northeast regions. Usage increased in the Central-West region, while the Southeast and South experienced steady declines from 2016 to 2023. The proportion of centers offering PD decreased from 51.6% in 2014 to 37.9% in 2023. Over time, the average age of PD patients increased, as did the proportion of Brown/Black individuals receiving PD. Despite these shifts, patient serum levels of hemoglobin, parathyroid hormone, and phosphorus remained stable. Conclusions: This study highlights a relative decline in PD availability and use within Brazil's public health system, with notable regional disparities. These findings underscore the urgent need for targeted policies to support PD infrastructure, funding, and training to ensure equitable access to RRT across the country.

The Burden of Alzheimer's Disease and Its Costs to a Healthcare System in a Large Population in Brazil

OBJECTIVES

In Brazil, cases of Alzheimer's disease (AD) are particularly prevalent in the southeastern region, including Minas Gerais, the largest state in the area. This study aimed to estimate the disease burden and healthcare costs from 2018 to 2022.

METHODS

Data on life expectancy, human development index, population size, and gross domestic product per capita were extracted to calculate disability-adjusted life-years (DALYs). Hospital admission data for AD were obtained from the Brazilian Unified Health System Department of Informatics (DATASUS) database, including the number of cases, deaths, age-specific data, and treatment costs. These variables, along with health, social, and environmental data, were processed to create risk factor layers, and the mean cost per DALY was calculated. Generalized estimating equation models were used to analyze the relationship between DALYs and various predictors, controlling for spatial autocorrelation. Maps were created to visualize the distribution of DALYs and cost per DALY.

RESULTS

There were 323 221 deaths from AD in Brazil, with cities averaging 3.61 deaths (range 1-73) and 5.43 hospitalizations (range 1-91) annually. The mean cost per city over these years was $9935.87 (range $44.22 to $787 307.93). In Minas Gerais, significant predictors of the estimated burden of AD include the percentage of the population aged 65 years and older, the human development index, and the prevalence of cardiovascular diseases. DALYs were higher than observed, indicating potential underreporting and insufficient resource allocation for AD treatment and prevention.

CONCLUSIONS

These results emphasize the need for region-specific policies and strategies to address the AD burden effectively. Policy makers should use this information to improve planning and allocate resources appropriately for treatment and prevention.

Intrinsic capacity and hospitalization among older adults: a nationally representative cross-sectional study

PURPOSE

Monitoring intrinsic capacity (IC) in community-dwelling older people can be potentially used to alert for adverse health outcomes. However, whether there is an association between IC and hospitalization has yet to be fully explored. This study aimed to investigate the association of the IC composite measure and its 5 domains with hospitalization in the previous year and length of hospital stay.

METHODS

We conducted cross-sectional analyses using data from a representative sample of community-dwelling adults (≥ 65 years). We assessed the IC domains (vitality, locomotor, cognitive, sensory, and psychological) using validated self-reported information and performance tests. We calculated standardized estimated scores (z scores) for IC composite measure and domains and conducted multivariate logistic and ordinal regressions. The primary outcomes were hospitalizations in the previous year and length of hospital stay.

RESULTS

In a sample of 5354 participants (mean age = 73 ± 6 years), we found that participants with high IC composite z scores were less likely to have experienced hospitalization in the previous year (OR = 0.51; 95% CI = 0.44-0.58). Among those who were hospitalized, high IC scores were associated with short stays (OR = 0.87; 95% CI = 0.80-0.95). Cognitive and psychological domains were associated with hospitalizations, and the locomotor domain was related to length of hospital stay. The vitality domain was associated with both outcomes.

CONCLUSION

IC as a composite measure was associated with previous hospitalizations and length of stay. IC can help clinicians identify older people prone to adverse outcomes, prompting preventive integrated care interventions.

Frailty and spatialization of older adults in the city of Uberlândia with IVCF-20

OBJECTIVE

To describe the functional clinical profile of elderly people linked to primary health care, using the Functional Clinical Vulnerability Index (IVCF-20) and to spatialize those with the greatest functional decline by primary health care units in the municipality of Uberlândia, in the state of Minas Gerais (MG), in the year 2022.

METHODS

A cross-sectional study with secondary data from the Municipal Health Department of Uberlândia-MG. The variables were compared using Student's t-test, Mann Whitney test, Pearson's chi-square, and multinomial logistic regression to obtain the independent effect of each variable. The significance level adopted was 5% (p < 0.05). The georeferenced database in ArcGIS® was used.

RESULTS

47,182 older adults were evaluated with a mean age of 70.3 years (60 to 113 years), 27,138 of whom were women (57.52%), with a clear predominance of low-risk or robust older adults (69.40%). However, 11.09% are high-risk older adults and 19.52% are at risk of frailty. Older men had independently lower odds of moderate and high risk compared to older women (OR = 0.53; p < 0.001). A high prevalence of polypharmacy was observed, 21.40% of the older adult population, particularly in frail older adults, with a prevalence of 63.08%. There was a greater distribution of frail older adults around the central region of the municipality and in health units with a larger coverage area. The IVCF-20 made it possible to screen frailty in primary health care.

CONCLUSION

The instrument is capable of stratifying the risk of older adults in health care networks through primary health care, enabling the application of individualized preventive, promotional, palliative, or rehabilitative interventions, according to the clinical functional stratum of the older adult and the compromised functional domains. Risk stratification and spatial distribution of the frailest older adults can be a good strategy for qualifying health professionals with the aim of maximizing the autonomy and independence of the older adults.

Species Distribution, Typical Clinical Features and Risk Factors for Poor Prognosis of Super-Elderly Patients with Bloodstream Infection in China

Objective

Bloodstream infection (BSI) is characterized by high mortality, especially among these increasing super-elderly patients (≥85 years), and this study was conducted to understand the species distribution, typical clinical features and risk factors for poor prognosis of super-elderly patients with BSI.

Methods

Based on previous work, this retrospective study was performed by reviewing an ongoing prospective medical database in a comprehensive tertiary center in China, and all super-elderly patients with BSI in the past 6 years were enrolled in this study.

Results

Out of 5944 adult-patients with BSI, there were totally 431 super-elderly patients (≥85 years old) enrolled in this study and age ≥90 years accounted for 31.1% (134/431). Among these 431 super-elderly patients with BSI, 40 patients (9.3%) were diagnosed with BSI and the remained 401 super-elderly patients (90.7%) were defined as hospital-acquired BSI. The typical feature of these super-elderly patients with BSI was the high proportion of patients with various comorbidities, such as cardiovascular disease (83.8%), ischemic cerebrovascular disease (63.3%) and pulmonary infection (61.0%). The other typical feature was that most (60.1%) of these patients had been hospitalized for long time (≥28 days) prior to the onset of BSI, and most patients had received various invasive treatments, such as indwelling central venous catheter (53.1%) and indwelling urinary catheter (47.1%). Unfortunately, due to these adverse features above, both the 7-day short-term mortality (13.2%, 57/431) and the 30-day long-term mortality (24.8%, 107/431) were high. The multivariate analysis showed that both chronic liver failure (OR 7.9, 95% CI 2.3-27.8, P=0.001) and indwelling urinary catheter (OR 2.3, 95% CI 1.1-4.7, P=0.023) were independent risk factors for 7-day short-term mortality, but not for 30-day long-term mortality. In addition, the microbiology results showed that the most common species were associated with nosocomial infection or self-opportunistic infection, such as Staphylococcus hominis (18.3%), Staphylococcus epidermidis (11.8%), Escherichia coli (9.7%), Klebsiella pneumoniae (9.3%) and Candida albicans (8.6%, fungi).

Conclusion

Super-elderly patients with BSI had typical features, regardless of the pathogenic species distribution and their drug resistance, or clinical features and their risk factors for poor prognosis. These typical features deserved attention and could be used for the prevention and treatment of BSI among super-elderly patients.

Evidence of whole-body vibration exercises on body composition changes in older individuals: a systematic review and meta-analysis

Introduction: The aging process is associated with changes in body composition, including fat gain and skeletal muscle loss from middle age onward. Moreover, increased risk of functional decline and the development of chronic diseases are also related to aging. Objective: This systematic review and meta-analysis aimed to evaluate the effects of whole-body vibration exercise (WBVE), as a physical exercise, on body composition in people over 60 years of age. Methods: Searches were performed on PubMed, Scopus, Web of Science, and Embase. Only randomized clinical trials evaluating the effects of WBVE on body composition in older individuals were considered. The methodological quality of the studies involved was assessed using the Physiotherapy Evidence Database (PEDro) scale, recommendations from the Cochrane Collaboration were used to assess risk of bias, and quality of evidence was assessed using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology. RevMan 5.4 was used to calculate standardized mean differences and confidence intervals of 95% (CIs). Results: Eight studies were included in this review with a mean methodological quality score of 7.5, which is considered high quality on the PEDro scale. The included studies suggest that more robust research with protocols and well-designed comparison groups is required to better assess changes in the body composition of older individuals through WBVE. Quantitative results were calculated, with differences in weighted means, differences in standardized means, and 95% confidence intervals (CIs). Conclusion: WBVE evaluated by the studies included in this review did not demonstrate improvements in body composition, and no significant effect of WBVE was found on fat mass with standardized differences (SD = -1.92; 95% CI: -4.81 to -0.98; p = 0.19), lean mass with standardized mean differences (SMD = 0.06 CI 95% [-0.21; -0.33]; p = 0.67), or skeletal muscle mass with standardized differences (SD = 0.10; CI 95% [-1.62; 1.83]; p = 0.91). Therefore, to date, there is lack of adequate evidence to state that WBVE can benefit the body composition of men and women over 60 years of age. However, further studies are required to better understand the physiological impacts of WBVE on body composition.

Trends in Pneumococcal and Bacterial Meningitis in Brazil from 2007 to 2019

The pneumococcal conjugate vaccination (PCV) was introduced into the Brazilian Childhood National Immunization Program in 2010; however, universal pneumococcal vaccination for older adults has not been implemented yet. Our aim is to evaluate the trends in pneumococcal meningitis incidence and case fatality rate (CFR) across all age groups from 2007 to 2019 using data from the National Surveillance System. The pre-PCV (2007-2009) and post-PCV (2011-2019) periods were compared; changes in incidence and CFR were assessed by joinpoint regression. Additional analyses of bacterial meningitis were performed to compare the patterns and trends. Over the 13-year period, 81,203 and 13,837 cases were classified as bacterial and pneumococcal meningitis, respectively. S. pneumoniae was the main etiological agent of bacterial meningitis in adults aged ≥50 years and the most lethal in all age groups. In the post-PCV period, a 56.5% reduction in the average incidence was seen in pneumococcal meningitis in the pediatric population. In contrast, there was an increasing trend among adults. The CFR for pneumococcal and bacterial meningitis remained stable in most age groups during the study period. These findings highlight the value of expanding pneumococcal vaccination policies, including vaccines that provide better indirect protection from children to adults and broadening vaccination to older adults.

Temporal trends of morbidities, and risk and protective factors for noncommunicable diseases in elderly residents in Brazilian capitals

OBJECTIVE

To analyze the temporal trends of prevalence of morbidities, risk and protection factors for noncommunicable diseases in elderly residents in Brazilian capitals between 2006 and 2021.

METHODS

A time series study with data from the Surveillance System of Risk and Protective Factors for Chronic Diseases by Telephone Inquiry. The variables analyzed were: high blood pressure, diabetes, smoking, overweight, obesity, consumption of alcoholic beverages, soft drinks, fruits and vegetables, and the practice of physical activity. Prais-Winsten regression and Interrupted Time Series from 2006 to 2014 and 2015 to 2021 were used.

RESULTS

From 2006 to 2021, for the total elderly population, there was an increase in diabetes (19.2 to 28.4%), alcohol consumption (2.5 to 3.2%), overweight (52.4 to 60.7%) and obesity (16.8 to 21.8%), and a reduction in the prevalence of smokers (9.4 to 7.4%) and in soft drink consumption (17 to 8.7%). By the interrupted series, between 2015 and 2021, there was stability in the prevalence of diabetes, female smokers, overweight among men, obesity in the total and male population, and soft drink consumption.

CONCLUSION

Over the years, there have been changes and worsening in the indicators analyzed, such as an increase in diabetes, alcohol consumption, overweight, and obesity, which reinforces the importance of continuous monitoring and sustainability programs to promote the health, especially in the context of economic crisis, austerity, and COVID-19 pandemic.

Use of structural models to elucidate the occurrence of falls among older adults according to abdominal obesity: a cross-sectional study

BACKGROUND

Obesity is a risk factor for falls in older adults, but the effects of body fat distribution and its interaction with other factors are not well established.

OBJECTIVES

To verify the occurrence of falls among older adults with and without abdominal obesity and the effects of sociodemographic, health, and behavioral variables on this outcome.

DESIGN AND SETTING

A cross-sectional study in an urban area of Alcobaça, Brazil.

METHODS

Men and women older than 60 years with (270) and without (184) abdominal obesity were included. Sociodemographic, health, and behavioral data were collected using validated questionnaires in Brazil. Descriptive and path analyses were performed (P < 0.05).

RESULTS

The occurrence of falls was high in participants with abdominal obesity (33.0%). In both groups, a higher number of morbidities (β = 0.25, P < 0.001; β = 0.26, P = 0.002) was directly associated with a higher occurrence of falls. Among participants without abdominal obesity, a lower number of medications (β = -0.16; P = 0.04), a higher number of depressive symptoms (β = 0.15; P = 0.04), worse performance on the agility and dynamic balance tests (β = 0.37; P < 0.001), and lower functional disability for basic activities of daily living (β = -0.21; P = 0.006) were directly associated with the occurrence of falls.

CONCLUSION

Adults older than 60 years with abdominal obesity have a higher prevalence of falls. Different factors were associated with the occurrence of falls in both groups.

Inequalities in the use of health services in a municipality in Southern Brazil in 2019: a cross-sectional study

OBJECTIVE

to assess inequalities in the use of health services in a municipality in Southern Brazil.

METHODS

This was a population-based cross-sectional study conducted with adults living in the urban area of the municipality of Criciúma, state of Santa Catarina, Brazil, between March and December 2019; the research outcomes were medical consultation, dental visit, nutritional counseling and the use of the Brazilian National Health System (Sistema Único de Saúde - SUS); the exposures were age, schooling and income; inequalities were analyzed using the Slope index of inequality and equiplots.

RESULTS

A total of 820 individuals were studied; medical consultation was higher (14.2 percentage points [p.p.]), and dental visit was lower (-29.5 p.p.), in older adults, when compared to young people; dental visit (41.1 p.p.) and nutritional counseling (18.0 p.p.) were higher in individuals with higher level of education, when compared to those with lower level of education; the use of SUS was higher in older adults (21.3 p.p.), with lower level of education (-61.2 p.p.) and lower income (-51.6 p.p.), when compared to their peers.

CONCLUSION

in order to develop public policies, these inequalities should be taken into consideration.

Worldwide cancer statistics of adults over 75 years old in 2019: a systematic analysis of the global burden of disease study 2019

Background and purpose

Cancer has become one of the major killers of humanity due to the number of people over the age of 75 increasing with population ageing. The aim of this study was to analyse the incidence and mortality rates in people over 75 of 29 cancer types in 204 countries and regions, as well as the trends from 1990 to 2019.

Methods

Twenty-nine cancer types were collected from the Global Burden of Disease (GBD) 2019 database(https://vizhub.healthdata.org/gbd-results/). We collected global cancer data for 2019 in terms of sex, age, sociodemographic index (SDI), region, etc. The estimated annual percentage change (EAPC) was calculated to assess the trend of the cancer incidence and mortality rate from 1990 to 2019.

Results

In 2019, the number of new cancer cases and deaths among people 75 and older was almost 3 and 4.5 times that of 1990, respectively. From 1990 to 2019, there was a slow rise in incidence and a slight decline in mortality. There were significant differences in the cancer burden based on sex, age, region, and SDI. The cancer burden in men was higher than in women. In addition, the cancer burden varied from region to region. The highest cancer burden occurred in high-income North America. In addition, the higher the SDI was, the greater the burden of cancer. The incidence of cancer in high SDI was approximately seven times that of low SDI, and the trend of increase in high SDI was obvious. However, the trend of mortality in high SDI was decreasing, while it was increasing in low SDI.

Conclusions

The present study focused on the cancer burden in adults over 75 years old. The findings in the study could serve as the basis for an analysis of the types of cancers that are most prevalent in different regions. This is beneficial for strategies of prevention and treatment according to the characteristics of different countries and regions to reduce the burden of cancer in older adults.

Identifying multimorbidity clusters among Brazilian older adults using network analysis: Findings and perspectives

In aging populations, multimorbidity (MM) is a significant challenge for health systems, however there are scarce evidence available in Low- and Middle-Income Countries, particularly in Brazil. A national cross-sectional study was conducted with 11,177 Brazilian older adults to evaluate the occurrence of MM and related clusters in Brazilians aged ≥ 60 years old. MM was assessed by a list of 16 physical and mental morbidities and it was defined considering ≥ 2 morbidities. The frequencies of MM and its associated factors were analyzed. After this initial approach, a network analysis was performed to verify the occurrence of clusters of MM and the network of interactions between coexisting morbidities. The occurrence of MM was 58.6% (95% confidence interval [CI]: 57.0–60.2). Hypertension (50.6%) was the most frequent morbidity and it was present all combinations of morbidities. Network analysis has demonstrated 4 MM clusters: 1) cardiometabolic; 2) respiratory + cancer; 3) musculoskeletal; and 4) a mixed mental illness + other diseases. Depression was the most central morbidity in the model according to nodes’ centrality measures (strength, closeness, and betweenness) followed by heart disease, and low back pain. Similarity in male and female networks was observed with a conformation of four clusters of MM and cancer as an isolated morbidity. The prevalence of MM in the older Brazilians was high, especially in female sex and persons living in the South region of Brazil. Use of network analysis could be an important tool for identifying MM clusters and address the appropriate health care, research, and medical education for older adults in Brazil.

Factors related to the accumulation of healthy behavior among older adults attending primary Health Care

The adoption and maintenance of healthy behaviors contribute for its accumulation throughout life, which require more than information disclosure and recommendations. Biopsychosocial factors may work as barriers to adherence to healthier behaviors, and yet have been underexplored. The objective was to investigate the factors related to the accumulation of healthy behavior among older adults attending Primary Health Care. Cross-sectional analysis with 201 older adults from baseline of Longitudinal Investigation of Functioning Epidemiology (LIFE) was performed in a Southeastern Brazilian city. The Healthy Behavior Score (HBS), ranging from 0 to 8, was calculated by the sum of the following habits: Physical activity practice, healthy eating, water consumption, night sleep time, not smoking, not drinking alcohol, frequent social relations, and spirituality. A linear multivariate regression was performed to test the influence of biopsychosocial aspects on HBS, with 95% confidence interval. Higher number of healthy behaviors was related to high social support, better cognitive status, less depressive symptoms and lower functional performance. Additionally, age and resilience score were correlated to healthy behaviors, which were higher among women and those with sufficient income. Multivariate analysis revealed depressive symptoms, functional performance and education as independent predictors of HBS. Depressive symptoms, functional performance and education are predictors of accumulation of health behaviors, independently of health status, contextual and sociodemographic aspects. Higher social support partially contributed to the higher number of healthy behaviors, and should be considered in public health policies for healthy longevity.

Socio-spatial inequalities in healthy life expectancy in the elderly, Brazil, 2013 and 2019

The growth in longevity in Brazil has drawn attention to more useful population health measures to complement mortality. In this paper, we investigate socio-spatial differences in life expectancy and healthy life expectancy based on information from the Brazilian National Health Survey (PNS), 2013 and 2019. A three-stage cluster sampling with stratification of the primary sampling units and random selection in all stages was used in both PNS editions. Healthy life expectancy was estimated by Sullivan's method by sex, age, and Federated Units (UF). Severe limitations to at least one noncommunicable chronic disease (NCD) or poor self-rated health were used to define the unhealthy state. Inequality indicators and a Principal Component analysis were used to investigate socio-spatial inequalities. From 2013 to 2019, both life expectancy and healthy life expectancy increased. The analysis by UF show larger disparities in healthy life expectancy than in life expectancy, with healthy life expectancy at age 60 varying from 13.6 to 19.9 years, in 2013, and from 14.9 to 20.1, in 2019. Healthy life expectancy in the wealthiest quintile was 20% longer than for those living in the poorest quintile. Wide socio-spatial disparities were found with the worst indicators in the UF located in the North and Northeast regions, whether considering poverty concentration or health care utilization. The socio-spatial inequalities demonstrated the excess burden of poor health experienced by older adults living in the less developed UF. The development of strategies at subnational levels is essential not only to provide equal access to health care but also to reduce risk exposures and support prevention policies for adoption of health behaviors.

Impact of the COVID-19 Pandemic on Infectious Diseases in Brazil: A Case Study on Dengue Infections

Brazil is known for being a breeding ground for emerging infectious diseases (EIDs), such as Zika, dengue, and chikungunya. Given that it has been one of the countries most affected by the SARS-CoV-2 pandemic, this article aims to analyze the impact that the COVID-19 pandemic has had on the burden of infectious diseases in Brazil, especially that of dengue. Brazil is a unique territory with a heterogeneous population living in a tropical, wet climate favorable to infectious diseases. In addition, despite being one of the largest emerging economies in the world, the country has been exposed to political instability and a public health system that suffers from large funding shortfalls and a lack of coherent regulation. The findings from this study are multilayered. Firstly, as cases of COVID-19 rose at the start of the pandemic, cases of dengue declined drastically. This may be due, in part, to factors such as seasonal climate and distancing measures. Furthermore, the findings indicate that the diversion of resources away from dengue and other infectious diseases, and mobilization for COVID-19 testing and treatment, likely resulted in a serious underreporting of dengue. While Brazil has incorporated some of the lessons learned from past EID experience in responding to the COVID-19 pandemic, the analysis highlights how the country's structural problems present pitfalls in the epidemiological fight. It was concluded that in a country such as Brazil, where infectious disease outbreaks are only a matter of time, pandemic preparedness should be prioritized over pandemic response.

Depressive and subthreshold depressive symptomatology among older adults in a socioeconomically deprived area in Brazil

Depressive and subthreshold depressive symptomatology are common but often neglected in older adults.

OBJECTIVE

This study aimed to assess rates of depressive and subthreshold depressive symptomatology, and the characteristics associated, among older adults living in a socioeconomically deprived area of Brazil.

METHODS

This study is part of the PROACTIVE cluster randomised controlled trial. 3356 adults aged 60+ years and registered in 20 primary health clinics were screened for depressive symptomatology with the Patient Health Questionnaire-9 (PHQ-9). Depressive status was classified according to the total PHQ-9 score and the presence of core depressive symptoms (depressed mood and anhedonia) as follows: no depressive symptomatology (PHQ-9 score 0-4, or 5-9 but with no core depressive symptom); subthreshold depressive symptomatology (PHQ-9 score 5-9 and at least one core depressive symptom); and depressive symptomatology (PHQ-9 score ≥ 10). Sociodemographic information and self-reported chronic conditions were collected. Relative risk ratios and 95% CIs were obtained using a multinomial regression model.

RESULTS

Depressive and subthreshold depressive symptomatology were present in 30% and 14% of the screened sample. Depressive symptomatology was associated with female gender, low socioeconomic conditions and presence of chronic conditions, whereas subthreshold depressive symptomatology was only associated with female gender and having hypertension.

CONCLUSIONS

Depressive and subthreshold depressive symptomatology is highly prevalent in this population registered with primary care clinics. Strategies managed by primary care non-mental health specialists can be a first step for improving this alarming and neglected situation among older adults.

Analysis of demand and access to services in the last two weeks previous to the National Health Survey 2013 and 2019

OBJECTIVE

Compare the demand and use of health services between 2013 and 2019, and analyze the associated sociodemographic and health variables in 2019.

METHODS

Cross-sectional study with data from the National Health Survey (PNS) 2013 and 2019. The prevalence and 95% confidence intervals (95% CI) for the demand and use of health services were estimated. In 2019, the differences in the indicators were analyzed according to sociodemographic variables and the crude and adjusted by sex and age prevalence ratios (RP) were estimated.

RESULTS

There was an increase of 22% in the demand for health care in the last two weeks, going from 15.3% (95%CI 15.0-15.7) in 2013 to 18.6% (95%CI 18.3-19.0) in 2019. There was a reduction in use in the last two weeks, from 97% (95%CI 96.6-97.4) in 2013 to 86.1% (95%CI 85.4-86.8) in 2019, which was observed for most Federation Units. In 2019, the demand for care was greater among women, the elderly, those with high schooling, individuals with health insurance and poor self-rated health. They obtained greater access to health services in the fifteen days prior to the survey: men, children or adolescents up to 17 years of age, people with health insurance and poor health self-assessment.

CONCLUSION

The demand for health services has grown and reduced access in the last 15 days between 2013 and 2019. These differences may have been exacerbated by the austerity measures implemented in the country.

Hearing Loss and Its Burden of Disease in a Large German Cohort-Hearing Loss in Germany

OBJECTIVES/HYPOTHESIS

Hearing loss is the most common sensory impairment worldwide. It restricts patients in many aspects of their daily lives and can lead to social exclusion. Understanding this burden is a mandatory requirement for the care of those affected. Therefore, the aim of this study was to estimate the burden of hearing loss in a large German cohort.

STUDY DESIGN

Cohort study.

METHODS

The Gutenberg Health Study is designed as a single-center, prospective, and observational cohort study and representative for the city of Mainz, Germany, with its district. Participants were interviewed concerning common otologic symptoms and tested by pure-tone audiometry. The primary outcome was hearing impairment stratified by age and sex. The prevalence of tinnitus was estimated for a subcohort to calculate disability-adjusted life years (DALYs). All results were weighted by the European Standard Population (ESP) 2013.

RESULTS

A total of 5,024 participants (mean age: 61.2 years, 2,591 men and 2,433 women) were included in the study. Hearing impairment showed the following prevalence: 28.2% (95% confidence interval [CI], 26.9%-29.4%) mild impairment, 10.1% (95% CI, 9.3%-11.0%) moderate impairment, 2.3% (95% CI, 1.9%-2.7%) moderately severe impairment, 0.2% (95% CI, 0.1%-0.4%) severe impairment, 0% (95% CI, 0.0%-0.1%) profound impairment, and 0.1% (95% CI, 0.0%-0.2%) complete impairment. Weighted for the ESP 2013 (all ages), hearing impairment across all levels (with/without tinnitus) causes a total of 2,118.97 DALYs per 100,000.

CONCLUSION

With 40.9% affected, the hearing loss represents a relevant burden of the German population. Understanding this will provide the basis for future guidelines on how to care for these patients.

Reasons for nonadherence to vaccination for influenza among older people in Brazil

This study aimed to estimate the prevalence of non-vaccination and the reasons for nonadherence to the influenza vaccine among older Brazilians according to sociodemographic characteristics. A cross-sectional study was conducted with data from older people (≥ 60 years of age; n = 23,815) who participated in the 2013 National Health Survey. Frequencies of non-vaccination and the main reasons for nonadherence were calculated with respective 95% confidence intervals. The prevalence of non-vaccination was 26.9% (approximately 7,106,730 older people). The reason rarely gets the flu was the most cited among the men (28.2%), the 60-to-69-year-old age group (29.6%), individuals with higher education (41.9%), and those with health insurance (32.3%). Fear of a reaction was the most cited reason in the northeastern region (25.4%), among women (29.3%), longer-lived individuals (≥70 years; 28.7%), and those who did not know how to read/write (26.7%). A total of 12.1% reported not believing in the vaccine's protection, and 5.5% did not know that it was necessary to take vaccine. The proportions of the main reasons for non-vaccination varied by sociodemographic characteristics. This study's findings highlight the need to increase older people's knowledge regarding influenza and influenza vaccines. Healthcare providers should be encouraged to counsel older people-especially those in subgroups with lower adherence, such as residents in the Northeast region, those aged 60-69 years, those who do not know how to read/write, those without a spouse/companion, and those without health insurance-regarding the different aspects of the vaccine and formally indicate it for groups at risk.

The Health Impact Fund: making the case for engagement with pharmaceutical laboratories in Brazil, Russia, India, and China

Despite progress in global health, the general disease burden still disproportionately falls on low- and middle-income countries. The health needs of these countries' populations are unmet because there is a shortage in drug research and development, as well as a lack of access to essential drugs. This health disparity is especially problematic for diseases associated with poverty, namely neglected tropical diseases and microbial infections. Currently, the pharmaceutical landscape focuses on innovations determined by profit margins and intellectual property protection. To expand drug accessibility and catalyze research and development for neglected diseases, a team of researchers proposed the Health Impact Fund as a potential solution. However, the fund is predominantly considering partnerships with pharmaceutical giants in high-income countries. This commentary explores the limitations and benefits in partnering with pharmaceutical companies based in Brazil, Russia, India, and China (BRIC), with the goal of expanding the Health Impact Fund's vision to incorporate long-term, local partnerships. Identified limitations to a BRIC country partnership include lower levels of drug development expertise compared to their high-income pharmaceutical counterparts, and whether the Health Impact Fund and the participating stakeholders have the financial capability to assist in bringing a new drug to market. However, potential benefits include the creation of new incentives to fuel competitive local innovation, more equitable routes to drug discovery and development, and a product pipeline that could involve stakeholders in lower- and middle-income countries. Our commentary explores how partnership with pharmaceutical firms in BRIC countries might be advantageous for all: The Health Impact Fund, pharmaceutical companies in BRIC economies, and stakeholders in low- and middle- income countries.
