Edentulism-free life expectancy among older Brazilian adults: SABE study, 2006-2016.

AIM: To assess edentulism-free life expectancy (EFLE) and the related inequalities by sex and schooling among older Brazilian adults from 2006 to 2016. BACKGROUND: Tooth loss is related to shortened longevity and unhealthy life expectancy in old age. MATERIALS AND METHODS: The outcome of the study was EFLE, assessed by age, sex and schooling. EFLE was estimated using the Sullivan method, considering the years and proportion of remaining life and the prevalence of edentulism-assessed in the Health, Well-being, and Aging cohort study, as well as the official mortality data for adults aged 60 years or older living in São Paulo, Brazil. RESULTS: EFLE increased from 10.9 (95% CI: 10.4-11.5) to 13.8 (95% CI: 13.2-14.5) years, considering data from 2006 to 2016, among 60-year-old individuals. In relative terms, these individuals expected to live 50.7% (95% CI: 48.1-53.2) of their remaining life free of edentulism in 2006, while this expectation was 62.8% (95% CI: 60.0-65.6) in 2016. Within both years, women and the less educated had lower EFLE than men and the higher educated. CONCLUSION: EFLE increased from 2006 to 2016. However, inequalities concerning sex and education remained significant, thereby highlighting the need to continuously address inequalities in tooth loss throughout life to contribute to a healthy ageing.

[CSP in 40 years of scientific publications]. / CSP em 40 anos de publicação científica.

In 2024, Cadernos de Saúde Pública (CSP) celebrates 40 years of uninterrupted publications. This article analyzes the trajectory of the journal and projects its future considering contemporary challenges in scientific publishing in the field of Public Health. This study was based on the analysis of main editorial policy milestones and the identification of the most popular topics. Three periods were recognized. In the "beginning" (1985 to 1990), the journal had restricted circulation, with a quarterly frequency. The word "epidemiology", used in a descriptive context, is highlighted. Then, in the period of "consolidation" (1991 to October 2012), CSP was indexed in the Index Medicus-MEDLINE database and had its online collection published by the Scientific Electronic Library Online (SciELO), expanding the reach of articles. In this period, the words that characterize the field of policy, planning, and management were clearly seen, and terms related to the epidemiological method emerged. The period of "diversity" (November 2012 to November 2023) introduced the requirement of an external editor to the Oswaldo Cruz Foundation's staff among the three co-editors-in-chief, aiming to ensure editorial independence. New activities and a similar frequency among the five most common terms highlight such "diversity". Several issues are observed in scientific publishing in 2024: non-commercial Open Science, artificial intelligence, appreciation of science, scientific dissemination, among others. Addressing new challenges in an ethical and transparent manner will allow future advances, maintaining CSP's credibility among authors and readers and its commitment to improvements in the living and health conditions of populations.

Clinical trials of COVID-19 vaccine development: a global overview.

This study aims to report analyses regarding the global distribution of institutions involved in clinical trials of COVID-19 vaccines throughout February 2022. We retrieved global data from the World Health Organization report on vaccine development. These data allowed us to identify project institutions and plot their geographic coordinates. We produced a georeferenced map using an R programming environment and, based on the geographical location of vaccine developers, we analyzed the subcontinental distribution of clinical trials and the nature of the vaccines. Regionally, South-Southeast Asian countries carried out more clinical trials than any other region, proportionally, although this happened solely for mature technologies. Few trials were under implementation in Latin America and Africa. Our findings confirm previous studies on the regional concentration in the development of technology. However, our contribution lies in showing these phenomena for COVID-19 vaccines in specific subcontinents and technologies, at a country level. Our data underscores which subcontinents perform very few clinical trials for COVID-19 and seem to be ill-prepared for future disease outbreaks, and if these become epidemics or even pandemics and require domestic vaccine development or production. We also consider the case of Brazil, which did not finish the complete cycle of COVID-19 vaccine development in the indicated period; but, with favorable policies, it has potential to engage further in COVID-19 vaccine technology.

Population mobility, demographic, and environmental characteristics of dengue fever epidemics in a major city in Southeastern Brazil, 2007-2015.

Around 14% of world dengue virus (DENV) cases occur in the Americas, most of them in Brazil. While socioeconomic, environmental, and behavioral correlates have been analyzed thoroughly, the role played by population mobility on DENV epidemics, especially at the local level, remains scarce. This study assesses whether the daily pattern of population mobility is associated with DENV incidence in Campinas, a Brazilian major city with over 1.2 million inhabitants in São Paulo State. DENV notifications from 2007 to 2015 were geocoded at street level (n = 114,884) and combined with sociodemographic and environmental data from the 2010 population census. Population mobility was extracted from the Origin-Destination Survey (ODS), carried out in 2011, and daily precipitation was obtained from satellite imagery. Multivariate zero-inflated negative binomial regression models were applied. High population mobility presented a relevant positive effect on higher risk for DENV incidence. High income and residence in apartments were found to be protective characteristics against the disease, while unpaved streets, number of strategic points (such as scrapyards and tire repair shops), and precipitation were consistently risk factors.

Life expectancy with negative physical oral health impact on quality of life in older adults.

Oral impairments can affect overall health and life expectancy in older adults. Our study evaluates the life expectancy with negative physical oral health impact on quality of life (POHIQoL) among older adults. Life expectancy with negative POHIQoL was estimated by the Sullivan method, using the prevalence of POHIQoL - obtained in the Health, Well-being and Ageing (SABE Study); and official mortality data for adults aged 60 years or older living in São Paulo, Brazil. Between 2000 and 2010, negative POHIQoL increased from 23.4% (95%CI: 20.2-26.9) to 30.4% (95%CI: 27.0-34.3) among older adults; total life expectancy increased from 22 and 17.5 to 23.7 and 19.4 years among 60-year-old women and men, respectively; and the proportion of remaining years to be lived with negative POHIQoL increased from 25.1% to 32.1% for the same age group. In both years, individuals aged 60 years with lower education level were expected to live more years with negative POHIQoL when compared with the most schooled ones (2000: 15.9 [95%CI: 15.0-16.8] vs. 14.3 [95%CI: 13.7-14.8]; 2010: 16.3 [95%CI: 15.1-17.4] vs. 14.1 [95%CI: 13.2-15.1]). Similarly, women were expected to live more years with negative POHIQoL than men. Within ten years, life expectancy with negative POHIQoL increased, as well as the existence of inequalities in sex and education level among Brazilian older adults. Expansion in coverage and focus on equity in dental care are still necessary to overcome persistent dental-related problems and inequalities and, therefore, contribute to healthy ageing.

SPNeoDeath: A demographic and epidemiological dataset having infant, mother, prenatal care and childbirth data related to births and neonatal deaths in São Paulo city Brazil - 2012-2018.

SPNeodeath dataset includes births and deaths of infants during the neonatal period from São Paulo city between 2012 and 2018, containing more than 1.4 million records. The dataset was created from SINASC and SIM Brazilian information systems for births and deaths respectively. SINASC comprises information about demographic and epidemiological data for the infant, mother, prenatal care and childbirth. SIM collects information about mortality, and it is used as the basis for the calculation of vital statistics, such as neonatal mortality rate. SIM was only used to label records from SINASC, when the death happened until 28 days of life. SPNeodeath has 23 variables with socioeconomic maternal condition features, maternal obstetrics features, newborn related features and previous care related features, besides a label feature describing if the subject survived, or not, after 28 days of life. In order to build the dataset, DBF files were downloaded from DATASUS ftp repository and converted to CSV format, the R programming language, and then the CSV files were processed using Python programming language. Features with incorrect values and unknowing information were removed.

Towards neonatal mortality risk classification: A data-driven approach using neonatal, maternal, and social factors.

Infant mortality is an important health measure in a population as a crude indicator of the poverty and socioeconomic level. It also shows the availability and quality of health services and medical technology in a specific region. Although improvements have been observed in the last decades, the implementation of actions to reduce infant mortality is still a concern in many countries. To address such an important problem, this paper proposes a new support decision approach to classify newborns according to their neonatal mortality risk. Using features related to mother, newborn, and socio-demographic, we model the problem using a data-driven classification model able to provide the probability of a newborn dying until 28 t h days of life. More than a theoretical study, decision support tools as the one proposed here is relevant in countries in development as Brazil, because it aims at identifying risky neonates that may die to raise the attention of medical practitioners so that they can work harder to reduce the overall neonatal mortality. Overcoming an AUC of 96%, the proposed method is able to provide not just the probability of death risk but also an explicable interpretation of most important features for model decision, which is paramount in public health applications. Furthermore, we provide an extensive analysis across different rounds of experiments, including an analysis of pre and post partum features influence over data-driven model. Finally, different from previously conducted studies which rely on databases with less than 100,000 samples, our model takes advantage from a new proposed database, constructed using more than 1,400,000 samples comprising births and deaths extracted from public records in São Paulo-Brazil from 2012 to 2018.

Edentulism and all-cause mortality among Brazilian older adults: 11-years follow-up.

We assessed the association between edentulism and all-cause mortality among community-dwelling older adults from São Paulo, Brazil, from 2006 to 2017. This prospective cohort study used data from the Health, Well-being and Aging Study (SABE, Portuguese acronym). Edentulism was evaluated by means of clinical oral examination and all-cause mortality data were obtained from state official records. Covariates included socioeconomic factors (age, sex, and schooling); health behavior (smoking, alcohol intake, and physical activity); dental care (prostheses use); general health (multimorbidity); and nutritional status (underweight). Kaplan-Meier survival curves were stratified by edentulism and compared using the log-rank test. Cox proportional hazards model was applied to calculate hazard ratios (HRs) for the association between edentulism and mortality after adjusting for covariates. The study sample included 1,687 participants (age, 60-102 years; edentulous: 47.2%). In the 11 years of follow-up, we analyzed 10,494 person-years and 566 deaths. In bivariate analysis, edentulous older adults were found to be at a higher risk of dying from all causes than the dentate participants (HR: 1.81; 95%CI: 1.53-2.15). After sequential adjustment for socioeconomic factors, health behavior, dental care, general health, and nutritional status, this association was attenuated, but remained significant (HR: 1.34; 95%CI: 1.10-1.63). In conclusion, edentulism is a significant predictor of all-cause mortality among older adults.

Factors associated with balance disorders of elderly living in the city of São Paulo in 2006: evidence of the Health, Well-being and Aging (SABE) Study. / Fatores associados às alterações de equilíbrio em idosos residentes no município de São Paulo em 2006: evidências do Estudo Saúde, Bem-Estar e Envelhecimento (SABE).

OBJECTIVE: To analyze the influence of demographic, health condition, and lifestyle factors on body balance disorders among elderly subjects living in the city of São Paulo, Brazil, in 2006. METHODS: Thestudy was developed based on information provided by the Health, Well-being, and Aging (SABE) Study. Itincluded 60-year-old subjects, both men and women, or those over this age. The sample comprised 1,226 subjects that represented 930,639 elderly subjects. The dependent variable was the elderly's body balance disorder, which was measured using part of the Short Physical Performance Battery (SPPB). The independent variables were divided into three groups: demographic, health conditions, and lifestyle. The multiple binary logistic regression analysis was applied to estimate the association between balance disorders and demographic, health, and lifestyle variables in the elderly. RESULTS: Age, difficulties in at least one mobility, and performance of regular physical activities showed a significant influence on the elderly's body balance (p < 0.05). Age was the strongest related determiner. Being aged 75-79 years and 80 years or more increased 3.77 and 5.31 times, respectively, the chances of the elderly subjects present balance disorders in comparison with the 60- to 64-years-old. CONCLUSION: Preventive measures that aim at reversing a body instability condition should be preconized and incorporated in the elderly's health-care schedule.

OBJETIVO: O objetivo deste estudo foi investigar a influência dos fatores demográficos, de condições de saúde e de estilo de vida nas alterações do equilíbrio corporal dos idosos residentes no município de São Paulo em 2006. MÉTODOS: O estudo foi desenvolvido com base em dados provenientes do Estudo Saúde,Bem-Estar e Envelhecimento (SABE). Foram selecionados todos os indivíduos com 60 anos e mais de idade, de ambos os sexos. A amostra considerada era de 1.226 indivíduos, representando 930.639 idosos. A variável dependente foi a alteração de equilíbrio corporal do idoso. Para mensurá-la utilizou-se parte do Short Physical Performance Battery (SPPB). As variáveis independentes foram classificadas em três grupos: demográficas, de condições de saúde e de estilo de vida. Para estimar a associação entre as alterações de equilíbrio com as variáveis demográficas, de saúde e de estilo de vida em idosos foi realizada uma análise de regressão logística binária múltipla. RESULTADOS: Idade, dificuldades em pelo menos uma mobilidade e realização de atividade física regular exercem uma significativa influência no equilíbrio corporal dos idosos (p < 0,05). A idade foi o determinante mais fortemente relacionado. Ter idade entre 75 a 79 anos e 80 anos e mais aumenta em 3,77 e 5,31vezes a chance, respectivamente, de os idosos apresentarem alterações de equilíbrio em comparação às idades de 60 a 64 anos. CONCLUSÃO: Medidas preventivas e que visam reverter um quadro de instabilidade corporal devem ser preconizadas e incorporadas na agenda de atenção à saúde dos idosos.

Inequalities in Life Expectancy With Frailty Among Brazilian Older Adults: A Multistate Approach.

BACKGROUND AND OBJECTIVES: Frailty is considered one of the major conditions faced by aging societies. Little has been reported about the effect of becoming frail on life expectancy among older adults in developing countries. The aim was to estimate total life expectancy and life expectancy with or without frailty by age, sex, and education among older adults in Brazil.Data and Methods: The study was developed based on information provided by the Health, Well-being, and Aging (SABE) Study. The sample included 1,399 older adults (≥60 years old) followed up from 2006 to 2010. Frailty status was classified according to the Fried criteria. Additional variables include age (in years), gender, and years of education. Estimates of total life expectancy, frailty-free life expectancy, and frailty life expectancy were obtained using the multistate life table method. RESULTS: At the baseline, the proportion of individuals with frailty was 13.7% and participants had, on average, 4.0 years of education. Men had more years of education than women (4.6 vs. 3.7, p < .001). Older adults with higher education live fewer years with frailty. Compared with older adults with no education, those with 6 years of education have higher frailty-free life expectancy. At age 70, men with no education expect to live 9.1 years (95% confidence interval [CI] = 7.8, 10.4) without frailty compared with 10.6 years (95% CI = 9.4, 11.8) among those with 6 years of education. Among women age 70, frailty-free life expectancy reaches 11.7 years (95% CI = 10.6, 12.8) among those with no education, but 13.9 years (95% CI = 12.5, 15.3) among those with 6 years. IMPLICATIONS: Given the recent changes in educational achievement in Brazil, we believe that educational policies are powerful ways in addressing inequalities in healthy life expectancy. Public health policies aimed at avoiding the development of frailty among elderly at risk should be encouraged.

[Health profile of the elderly in Brazil: analysis of the 2003 National Household Sample Survey using the Grade of Membership method]. / Perfis de saúde dos idosos no Brasil: análise da Pesquisa Nacional por Amostra de Domicílios de 2003 utilizando o método Grade of Membership.

The aim of this study was to identify functional disability and health profiles of the elderly in Brazil, as well as their prevalence rates, based on the National Household Sample Survey for 2003. The sample size was 33,786 elderly individuals. Grade of Membership was used to define the profiles: "healthy elderly" (Profile 1), whose pure types had a lower probability of disability and chronic illness; "elderly with mild functional disability" (Profile 2), whose pure types had mainly hypertension and lower back problems and were independent in activities of daily living, although with high difficulty in mobility; and "elderly with severe disability" (Profile 3), with higher probability of chronic illness, high difficulty with activities of daily living, and high dependency in terms of mobility. In conclusion, the profiles indicate that a consistent approach to functional disability is essential for promoting the health of the elderly.

[Inequality in access to health services between urban and rural areas in Brazil: a disaggregation of factors from 1998 to 2008]. / Desigualdade no acesso à saúde entre as áreas urbanas e rurais do Brasil: uma decomposição de fatores entre 1998 a 2008.

Access to healthcare is an important dimension of inequalities between urban and rural areas. Access is lower in rural areas due to the population's greater social vulnerability and greater difficulties in access among its social groups. Based on data from the health supplement of the Brazilian National Household Sample Survey, we analyzed the determinants of access and differences between urban and rural areas from 1998 to 2008. The analysis of determinants of access to health services used binary logistic regression. Differences between urban and rural areas were disaggregated as observable factors (enabling, need, and predisposing) and non-observable factors (supply and difficulty in access). The results highlight that inequality in access is higher in rural areas. Need factors are fundamental determinants of access to health, while enabling factor are more important for explaining the differences between urban and rural areas. The slight reduction in differences during the period was due mainly to changes in the rural population's composition.

O acesso à saúde é uma importante dimensão das desigualdades entre áreas urbanas e rurais. O acesso é menor nas áreas rurais em função da maior vulnerabilidade social de sua população e das maiores dificuldades de acesso que seus grupos sociais estão submetidos. A partir de dados do suplemento de saúde da Pesquisa Nacional por Amostra de Domicílios, foram analisados os determinantes do acesso e das diferenças entre áreas urbanas e rurais nos anos de 1998 a 2008. A análise dos determinantes do acesso aos serviços de saúde foi realizada pelo modelo de regressão logística binária. As diferenças entre áreas urbanas e rurais foram decompostas em fatores observáveis (fatores de capacitação, necessidade e predisposição) e não observáveis (oferta e dificuldade de acesso). Os resultados destacam que a desigualdade de acesso é elevada e maior nas áreas rurais. Os fatores de necessidade são determinantes fundamentais do acesso à saúde, enquanto que os fatores de capacitação são mais importantes para explicar as diferenças entre as áreas urbanas e rurais. A tênue redução das diferenças no período se deveu fundamentalmente a mudanças na composição da população rural.

El acceso a la salud es una importante dimensión de las desigualdades entre áreas urbanas y rurales. El acceso es menor en las áreas rurales, en función de una mayor vulnerabilidad social de su población y de las mayores dificultades de acceso a la que están sometidos sus grupos sociales. A partir de los datos del suplemento de salud de la Encuesta Nacional por Muestra de Domicilios, se analizaron los determinantes de acceso y diferencias entre áreas urbanas y rurales, desde el año 1998 a 2008. El análisis de los determinantes de acceso a los servicios de salud se realizó mediante un modelo de regresión logística binaria. Las diferencias entre áreas urbanas y rurales se dividieron en factores observables (factores de capacitación, necesidad y predisposición) y no observables (oferta y dificultad de acceso). Los resultados destacan que la desigualdad de acceso es elevada y superior en las áreas rurales. Los factores de necesidad son determinantes fundamentales del acceso a la salud, mientras que los factores de capacitación son más importantes para explicar las diferencias entre áreas urbanas y rurales. La tenue reducción de las diferencias en el período se debió fundamentalmente a cambios en la composición de la población rural.

Clinical trials of COVID-19 vaccine development: a global overview / Ensaios clínicos de desenvolvimento de vacinas contra a COVID-19: uma visão global / Ensayos clínicos de desarrollo de vacunas contra el COVID-19: una descripción general

Abstract: This study aims to report analyses regarding the global distribution of institutions involved in clinical trials of COVID-19 vaccines throughout February 2022. We retrieved global data from the World Health Organization report on vaccine development. These data allowed us to identify project institutions and plot their geographic coordinates.

However, our contribution lies in showing these phenomena for COVID-19 vaccines in specific subcontinents and technologies, at a country level. Our data underscores which subcontinents perform very few clinical trials for COVID-19 and seem to be ill-prepared for future disease outbreaks, and if these become epidemics or even pandemics and require domestic vaccine development or production. We also consider the case of Brazil, which did not finish the complete cycle of COVID-19 vaccine development in the indicated period; but, with favorable policies, it has potential to engage further in COVID-19 vaccine technology.

Resumo: O objetivo desta comunicação é relatar análises sobre a distribuição global das instituições envolvidas em ensaios clínicos relacionados às vacinas de COVID-19 até fevereiro de 2022. Obtivemos dados globais da Organização Mundial da Saúde sobre o desenvolvimento de vacinas. Isso nos permitiu identificar as instituições de projetos e traçar as suas coordenadas geográficas. Produzimos um mapa georreferenciado usando a linguagem de programação R e, a partir da localização geográfica dos desenvolvedores de vacinas, analisamos a distribuição subcontinental dos ensaios clínicos e a natureza das vacinas testadas. Regionalmente, os países do Sul-Sudeste Asiático realizaram proporcionalmente mais ensaios clínicos do que qualquer outra região, embora isso tenha acontecido para tecnologias maduras. Poucos ensaios estavam em fase de implementação na América Latina e na África. Nossos achados confirmam estudos anteriores sobre a concentração regional no desenvolvimento de tecnologia. No entanto, a nossa contribuição está em demonstrar esses fenômenos para vacinas contra a COVID-19 em subcontinentes e tecnologias específicas em nível nacional. Os nossos dados ressaltam quais subcontinentes realizam muito poucos ensaios clínicos para COVID-19 e parecem estar mal preparados para futuros surtos de doenças e no caso de esses se tornarem epidemias ou mesmo pandemias e exigirem desenvolvimento ou produção de vacinas domésticas. Consideramos também o caso do Brasil, que não encerrou o ciclo completo de desenvolvimento da vacina contra a COVID-19 no período indicado; mas, com políticas favoráveis, tem potencial para se envolver ainda mais na tecnologia de vacinas contra a COVID-19.

Resumen: El propósito de este texto es reportar un análisis sobre la distribución global de instituciones involucradas en ensayos clínicos relacionados con vacunas del COVID-19 hasta febrero de 2022. Se recogieron datos globales de la Organización Mundial de la Salud sobre el desarrollo de vacunas; lo que se pudo identificar las instituciones del proyecto y rastrear sus coordenadas geográficas. Se elaboró un mapa georreferenciado utilizando el lenguaje de programación R y, a partir de la ubicación geográfica de los desarrolladores de vacunas, se analizó la distribución subcontinental de los ensayos clínicos y la naturaleza de las vacunas probadas. A nivel regional, los países del Sur Sureste Asiático llevaron a cabo proporcionalmente más ensayos clínicos que cualquier otra región, aunque esto se realizó con tecnologías consolidadas. Se registraron pocos ensayos en la etapa de implementación en América Latina y África. Los hallazgos confirman los estudios previos sobre la concentración regional en el desarrollo tecnológico. Sin embargo, permiten un aporte al demostrar estos fenómenos para vacunas contra el COVID-19 en subcontinentes y tecnologías específicas a nivel nacional. Los datos revelan los subcontinentes que realizan pocos ensayos clínicos para el COVID-19 y que no parecen estar bien preparados para futuros brotes de enfermedades, en caso de que se conviertan en epidemias o incluso pandemias, requiriendo el desarrollo o la producción de vacunas nacionales. Se considera también el caso de Brasil, que no completó el ciclo completo de desarrollo de la vacuna contra el COVID-19 en el periodo señalado; pero, con políticas favorables, tiene el potencial de involucrarse aún más en la tecnología de la vacuna del COVID-19.

Frailty profile in Brazilian older adults: ELSI-Brazil.

OBJECTIVE: To estimate the prevalence of frailty and to evaluate the associated factors in the non-institutionalized Brazilian population aged 50 years or older. METHODS: The analyses were conducted in 8,556 participants of the baseline survey of the Longitudinal Study of Health of the Brazilian Elderly (ELSI-Brazil) conducted in 2015 and 2016. Frailty was defined based on five characteristics: weight loss, weakness, slowness, exhaustion and low level of physical activity. Participants with three or more characteristics were classified as frail. A Poisson regression model was used to examine the association between frailty and sociodemographic and health factors. RESULTS: The prevalence of frailty was 9.0% (95%CI 8.0-10.1) among participants aged 50 years or over. Among the older adults aged 60 or over, the prevalence was 13.5% (95%CI 11.9-15.3) and 16.2% (95%CI 14.3-18.3) among those 65 aged years or over. Factors associated with higher prevalence of frailty were low schooling, residence without a partner, health conditions (poor self-rated health and two or more chronic diseases) and limitation to perform basic activities of daily living. CONCLUSIONS: The prevalence of frailty among Brazilians aged 65 years or older is similar to their European counterparts. Poor health conditions, functional limitation and low schooling emerge as the factors most strongly associated with the frailty in this population.

[The effect of chronic diseases on functional status of the elderly living in the city of São Paulo, Brazil]. / A influência das doenças crônicas na capacidade funcional dos idosos do Município de São Paulo, Brasil.

The main focus of this study was the effect of chronic disease (hypertension, diabetes mellitus, heart disease, lung disease, cancer, and arthropathy) on the functional status (activities of daily living - ADL, instrumental activities of daily living - IADL) among the elderly, controlling for age, gender, living arrangements, education, and comorbidity. The analysis was based on information provided by the SABE Project, from the city of São Paulo, Brazil, including individuals 60 years of age and over (n = 1,769), from January 2000 to March 2001. A multinomial logistic regression model was used. Compared to the absence of dependency category, heart disease (OR = 1.82), arthropathy (OR = 1.59), lung disease (OR = 1.50), and hypertension (OR = 1.39) were the main diseases that affected the IADL dependency category. Lung disease (OR = 2.58), arthropathy (OR = 2.27), hypertension (OR = 2.13), and heart disease (OR = 2.10) had important impact on the IADL and ADL dependency categories. The results were statistically significant (p < 0.05).
