RESUMO
OBJECTIVES: To estimate the incidence of dementia in a community-dwelling older population from São Paulo city, Brazil. METHODS/DESIGN: This two-phase prospective cohort study evaluated a representative cluster sample of 1370 individuals aged 60 years old and over from three different socioeconomic levels. The community screening phase consisted of a tested combination of cognitive and functional tests administered among the subjects and informants. In the hospital diagnosis phase, the Cambridge Examination was performed; the diagnosis of dementia and dementia subtypes was made according to DSM IV criteria. Incidence rates were expressed in person-years, multiplied by 1000. The risk of developing dementia was calculated using Cox regression. RESULTS: Among 1370 eligible subjects, 678 were accessed, and 489 completed the evaluation. Forty-two subjects were diagnosed with dementia. The incidence rate of dementia and Alzheimer's disease (AD) were 11.2 (95% CI: 8.0-15.1) and 8.9 (95% CI: 6.1-12.5) per 1000 person-years, respectively; there were high age-specific rates of dementia among younger individuals. There was a trend of a higher risk of developing AD for women than for men. Multivariate analysis showed that older age, the presence of diabetes and the presence of amnestic MCI increased the risk of developing dementia. CONCLUSIONS: The age-specific rates in younger individuals were expressively higher than in worldwide studies and supposedly affected by cardiovascular morbidity. The higher risk in women in a younger sample corroborated the interaction between sex and AD. The increased risk of amnestic MCI reinforced its contribution to the progression to dementia and AD.

Although several surveys have been conducted around the world, few surveys have investigated the prevalence of dementia in Latin America. The aim of this study was to estimate dementia prevalence in a community sample in Ribeirão Preto, Brazil, and to evaluate its distribution across several socio-demographic and clinical characteristics and habits. The population was aged 60 years and older and a representative sample from three different social regions. The screening instruments used in the first phase were the Mini-Mental State Examination, the Fuld Object-Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, and the Bayer Activities of Daily Living Scale. In the second phase, the Cambridge Examination was employed to diagnose dementia according to the DSM-IV criteria. The estimate of dementia prevalence was adjusted for screening instrument performance, using the positive and negative predictive values. The data were weighted to compare frequencies, considering the sampling and the non-response effect, and subjected to multivariate analysis. In all, 1.145 elderly subjects were evaluated (mean age: 70.9 years), of whom 63.4% were female and 52.8% had up to 4 years of schooling (participation rates at the first and the second phases were 62.6 and 60%, respectively). The observed and estimated prevalences of dementia were 5.9% and 12.5%, respectively (n = 68). Alzheimer's disease was the main cause (60.3%). Dementia was associated with old age, low education, stroke, absence of arthritis, and not reading books. The estimated prevalence of dementia was higher than the prevalence previously found. Associated factors confirmed the importance of intellectual activities in prevention.

BACKGROUND: Studies on functional capacity in community-dwelling older people have shown associations between declines in instrumental activities of daily living (IADL) and several factors. Among these, age has been the most consistently related to functional capacity independent of other variables. We aimed at evaluating the performance of a sample of healthy and cognitively intact Brazilian older people on activities of daily living and to analyze its relation to social-demographic variables. METHODS: We conducted a secondary analysis of data collected for previous epidemiological studies with community-dwelling subjects aged 60 years or more. We selected subjects who did not have dementia or depression, and with no history of neurological diseases, heart attack, HIV, hepatitis or arthritis (n = 1,111). Functional capacity was assessed using the Brazilian version of the Older American Resources and Services Questionnaire (BOMFAQ). ADL performance was analyzed according to age, gender, education, and marital status (Pearson's χ2, logistic regression). RESULTS: IADL difficulties were present in our sample, especially in subjects aged 80 years or more, with lower levels of education, or widowed. The logistic regression analysis results indicated that "higher age" and "lower education" (p ≤ 0.001) remained significantly associated with IADL difficulty. CONCLUSIONS: Functional decline was present in older subjects even in the absence of medical conditions and cognitive impairment. Clinicians and researchers could benefit from knowing what to expect from older people regarding IADL performance in the absence of medical conditions.

Idosos que atendem a determinados critérios demográficos, sociais e econômicos estão especialmente vulneráveis a adoecimento, incapacidades e morte. Desenvolveu-se estudo com o objetivo de identificar idosos vulneráveis segundo critérios determinados e comparar idosos vulneráveis e não-vulneráveis em relação à necessidade de ajuda para atividades. O estudo, de corte transversal, compreendeu coleta de dados com 190 idosos usuários de um Centro de Saúde Escola, em seus domicílios, entre 2006 e 2008, por meio de aplicação do Instrumento para Classificação de Idosos quanto à Capacidade para o Autocuidado. Cento e quarenta e cinco idosos (80%) estão submetidos a pelo menos um critério de risco; 99 (52,1%) referem uma ou mais dificuldades para atividades básicas, sendo que 29 (29,3%) requerem ajuda; 92 (48,4%) idosos mencionam dificuldades para atividades instrumentais e destes, 67 (72,8%) requerem ajuda. Somente 16 (8,4%) adotam práticas de autocuidado para minimizar suas dificuldades e 38 (20%) as adotam para compensar parte delas. O grupo de idosos que atende pelo menos a um critério de risco apresenta proporção maior de indivíduos que requer ajuda para atividades básicas e instrumentais de vida diária. Outras análises possibilitarão verificar a influência de cada critério sobre a funcionalidade. A realização de pesquisa sobre práticas de autocuidado com um maior número de indivíduos possibilitará comparação entre grupos que empregam ou não essas práticas e critérios de risco. Apesar das limitações do estudo, ele suscita planejamento de ações aos idosos com dificuldades e que requeiram ou não ajuda para suas atividades.
Elderly who match certain demographic, social and economic criteria are especially vulnerable to illness, disability and death. The study was developed in order to both identify vulnerable elderly according to specific criteria and compare vulnerable and non-vulnerable elderly with their need for assistance with activities. This cross-sectional study had its data collected in the household of 190 elderly users of a School Health Center. It took place between 2006 and 2008, through the application of the CICAc Instrument: classification of the aged concerning self-care ability. One hundred and forty-five elderly (80%) were under at least one risk criterion; 99 (52.1%) reported one difficulty or more in basic activities, and 29 (29.3%) of them require assistance; 92 (48.4%) elderly mention difficulties in instrumental activities and 67 (72.8%) require assistance. Only 16 (8.4%) adopt self-care practices to minimize their difficulties and 38 (20%) adopt them to compensate just part of their difficulties. The elderly group that is under at least one risk criterion has a higher proportion of individuals who require assistance with basic and instrumental activities of daily living. Further analysis may verify the influence of each criterion on the functionality. Carrying out research on self-care practices with a larger number of individuals will allow a comparison between groups that make or do not make use of these practices and match risk criteria. Despite the limitations of the study, it gives rise to the planning of interventions for the elderly that have difficulties and need assistance with their activities.

Objective: To evaluate the effect on quality of life of elderly people enrolled in the Grupo de Assistência Multidisciplinar ao Idoso Ambulatorial (GAMIA) of the Geriatric Service of the Hospital das Clínicas of the Faculdade de Medicina of Universidade de São Paulo. Methods: In 83 elderly participants of group between 2000 and 2002 the quality of life was assessed by the World Health Organization Quality of Life (WHOQOL-bref) at the beginning and the end of the program. Functionality was assessed by the Katz and Lawton scales and socio-demographic data were obtained from medical charts. Results: Females predominated (79.5%) and overall mean age was 69.30 years. Data analysis showed a reduction in the physical domain of WHOQOL-bref (p = 0.014) and increased psychological health and environment domains (p = 0.029 and p = 0.007 respectively), detecting a trend of increase in social relationships and in general domains (p = 0.062 and p = 0.052 respectively). Conclusions: The clinical evaluation of elderly may have the predominant factor for the deterioration of their perception in the physical domain because of the detection of previously unknown diseases and determination of the use of new drugs. Improvement in psychological health and the environment can be related to psychological and social support that the elderly received from peers and professionals and the benefits of group activities, as well as the upward trend observed in the social relationships and general domains. Participation in a program to promote healthy aging was effective in improving the quality of life of the elderly.
Objetivo: Avaliar os efeitos na qualidade de vida de idosos matriculados no Grupo de Assistência Multidisciplinar ao Idoso Ambulatorial (GAMIA) do Serviço de Geriatria do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Métodos: Nos 83 idosos participantes do grupo entre 2000 e 2002, a qualidade de vida foi avaliada pelo World Health Organization Quality of Life (WHOQOL-bref) no início e no fim do programa. A funcionalidade foi avaliada pelas Escalas de Katz e Lawton e os dados sociodemográficos foram obtidos nos prontuários. Resultados: Houve predomínio do sexo feminino (79,5%) e a média geral de idade foi de 69,30 anos. A análise dos dados mostraram uma redução no domínio físico do WHOQOL-bref (p = 0,014) e a elevação dos domínios psicológico e meio ambiente (p = 0,029 e p = 0,007, respectivamente), detectando-se tendência de elevação nos domínios relações sociais e geral (p = 0,062 e p = 0,052, respectivamente). Conclusões: Como a avaliação clínica desses idosos revelou doenças desconhecidas previamente e determinou a utilização de novos medicamentos, a percepção que os idosos tinham, em relação à sua saúde, pode ter sido o fator preponderante para a piora no domínio físico. A melhora dos domínios psicológico e meio ambiente pode estar relacionada ao suporte psicológico e social que o idoso recebeu dos colegas e profissionais e dos benefícios das atividades em grupo, bem como às tendência de elevação observada nos domínios relações sociais e geral. A participação em um programa de promoção do envelhecimento saudável mostrou-se eficaz na melhora da qualidade de vida do idoso.

RESUMO
The mini-mental state examination (MMSE) has been widely used as a screening instrument for cognitive disorders. Age, schooling and many other sociodemographic and health variables may be associated with a worse performance on the MMSE. The objectives of this study were to investigate the distribution of MMSE percentiles in a large Brazilian community-based elderly sample, divided according to age and schooling, and to evaluate the impact of sociodemographic and health variables on groups of elderly people with lower cognitive performance. The MMSE was applied to a sample of 2,708 adults, aged 60 years and older. Of this population, 1,563 individuals were living in the city of São Paulo, while 1,145 were living in the city of Ribeirão Preto. The subjects were divided into six groups according to the amount of schooling that they had received (no formal education, 1-4 and ≥5 years) and age (<75 and ≥75 years old). To each one of the subgroups a stepwise logistic regression was applied, considering the following dependent variable: subjects who scored under or above the 15th percentile on MMSE. High scores on a depression scale, high scores on a memory complaints scale and low socio-economic levels were associated with poorer performance on the MMSE. Being currently employed and being married were related to higher scores on the test. Many sociodemographic and health variables can influence MMSE performance, with impacts depending on age and schooling. Clinicians and primary care physicians should pay attention to variables that may be associated with worse cognitive performance.

BACKGROUND: Studies investigating the association between alcohol use and cognitive disorders in the elderly population have produced divergent results. Moreover, the role of alcohol in cognitive dysfunction is not clear. The aims of this study were to estimate the prevalence of alcohol-related problems in an elderly population from Brazil and to investigate their association with cognitive and functional impairment (CFI) and dementia. METHODS: A community-based cross-sectional study was performed. A sample of 1,145 elderly people was examined in 2 phases. Several instruments were utilized in the first phase: the CAGE questionnaire was used to identify potential cases of alcohol-related problems, and a screening test for dementia was used to estimate CFI. The CAMDEX interview (Cambridge Examination) and DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th edition) criteria were used for the clinical diagnosis of dementia in the second phase. RESULTS: "Heavy alcohol use" (CAGE > or = 2) was found in 92 subjects (prevalence: 8.2%). It was associated with gender (males, p < 0.001), low education (only in females, p = 0.002), and low socioeconomic level (p = 0.001, in females; p = 0.002, in males). The Mini Mental State Examination exhibited a nonlinear relationship with alcohol-related problems in females; "mild-moderate alcohol use" (CAGE < 2) presented the highest score. A significant association between alcohol-related problems and cognitive dysfunction was found only in females. "Heavy alcohol use" was associated with higher CFI and dementia rates compared to "mild-moderate alcohol use" (p = 0.003 and p < 0.001, respectively). "Mild-moderate alcohol use" had a tendency of association with lower CFI and dementia rates when compared to "no alcohol use" (p = 0.063 and 0.050, respectively). CONCLUSION: Our findings suggest that alcohol use does not have a linear relationship with cognitive decline.
