ABSTRACT Objective: To investigate differences in the prevalence of frailty between LGBT+ and non-LGBT+ older adults. Methods: A cross-sectional study involving Brazilians aged 50 and over was performed. The participants were invited to participate in an anonymous online survey between August 2019 and January 2020. The survey was widely distributed in neighborhood associations, day centers, non-governmental organizations, and social media. Those who identified as homosexual, bisexual, pansexual, non-heterosexual, transgender, travesti, or non-binary were grouped as LGBT+. Participants who were both cisgender and heterosexual were categorized as non-LGBT+. Frailty was measured using the FRAIL scale, and the participants were categorized as robust, prefrail, or frail. Generalized ordered logistic models were used to examine the adjusted association between LGBT+ status and frailty according to age and sex. Results: The study sample included 6,693 participants with a median age of 60 years. Overall, 1,332 patients were LGBT+ (19.9%), and 5,361 were non-LGBT+ (80.1%). Pre-frailty or frailty was observed in 656 (49%) LGBT+ participants and 2,460 (46%) non-LGBT+ participants (p=0.03). Multivariate analyses showed that being LGBT+ was independently associated with frailty in female participants aged ≥50 years (OR=1.52, 95%CI=1.08-2.13, p=0.02) and male participants aged ≥60 years (OR=2.83, 95%CI=1.41-5.69, p=0.004). Non-cisgender participants were also more likely to be frail than cisgender participants (OR=2.21, 95%CI=1.42-3.42, p<0.001). Conclusion: LGBT+ status was independently associated with frailty in female adults aged >50 years and males aged > 60 years. More research in this area and inclusive government policies are needed to promote the healthy aging of the LGBT+ population.

Abstract Objectives: To compare variables of access to healthcare between the LGBT+ population aged 50 and over and those non-LGBT+. Methods: A cross-sectional study was carried out in Brazil through a confidential online questionnaire. The use of the health system was characterized by the number of preventive tests performed and measured by the PCATool-Brasil scale (a 10-point scale in which higher scores were associated with better assistance in healthcare). The association between being LGBT+ and access to health was analyzed in Poisson regression models. Results: 6693 participants (1332 LGBT+ and 5361 non-LGBT+) with a median age of 60 years were included. In the univariate analysis, it was observed not only lower scores on the PCATool scale (5.13 against 5.82, p < 0.001), but a greater proportion of individuals among those classified with the worst quintile of access to healthcare (< 4 points), 31% against 18% (p < 0.001). Being LGBT+ was an independent factor associated with worse access to health (PR = 2.5, 95% CI 2.04‒3.06). The rate of screening cancer, for breast, colon, and cervical cancer was also found to be lower in the LGBT+ population. Conclusion: Healthcare access and health service experiences were worse in the LGBT+ group than in their non-LGBT peers. Inclusive and effective healthcare public policies are essential to promote healthy aging for all.

ABSTRACT Objective: To describe the first COVID-19 pandemic at Casa Ondina Lobo, a philanthropic nursing home in São Paulo city, and the containment measures against the pandemic that proved to be effective. Methods: Several preventive measures were taken before and during the pandemic, with emphasis on universal testing by reverse transcription polymerase chain reaction for COVID-19. All residents and employees were tested twice in a D9 period. Results: Among the 62 residents and 55 employees, in both testing, eight residents and nine employees tested positive for COVID-19. Of 22% of employees and 75% of residents evolved asymptomatic, emphasizing the importance of universal testing for the detection and isolation of these cases. A quarter of residents evolved without any symptoms, however, with COVID-19 signs, reinforcing the importance of monitoring vital signs. The second testing did not detect any new cases among residents, demonstrating the effectiveness of the containment measures, however, it found four new cases among employees. This emphasized their role in COVID-19 outbreaks in nursing homes. Only one patient died, a 12.5% lethality among those known to be infected and a 1.6% mortality in the total population of residents were seen. Conclusion: The adoption of appropriate containment measures enabled to contain an COVID-19 pandemic in studied nursing home. Universal reverse transcription polymerase chain reaction testing for COVID-19 has proved to be particularly important and effective.

RESUMO. Estudos dos efeitos da atividade física relataram melhora nos sintomas e na qualidade de vida de pacientes com doença de Parkinson (DP). Além disso, alterações morfológicas do cérebro após o exercício físico foram relatadas em modelos animais da DP. No entanto, essas mudanças relacionadas ao estilo de vida não foram avaliadas em tecido cerebral post-mortem. Objetivo: Avaliar a expressão de astrócitos, tirosina hidroxilase (TH) e a expressão de proteínas estruturais (neurofilamentos e microtúbulos — MAP2) por imuno-histoquímica, em amostras cerebrais post-mortem de indivíduos com corpos de Lewy. Métodos: Amostras com estágio de Braak para DP≥III, classificação neuropatológica, fornecidas pelo biobanco de estudos do envelhecimento foram classificadas em grupos ativos (n=12) e não ativos (n=12), de acordo com o estilo de vida (atividade física), e pareados por idade, sexo e estadiamento de Braak. Analisou-se a substância negra e gânglios da base. Resultados: Idade, sexo e classificação para DP foram semelhantes (p=1,00). Observou-se maior expressão de TH no grupo ativo (p=0,04). Amostras de não ativos revelaram maior expressão de astrócitos no mesencéfalo (p=0,03) e nos gânglios da base (p=0,0004); MAP2 nos gânglios da base (p=0,003); os níveis de neurofilamentos foram maiores na substância negra (p=0,006). Conclusão: O estilo de vida ativo parece promover efeitos positivos no cérebro, mantendo a síntese de dopamina e a expressão estrutural de proteínas no sistema nigrostriatal e com diminuição da ativação de astrócitos em indivíduos com a mesma classificação neuropatológica para a DP.

ABSTRACT. Clinical trials of the effects of physical activity have reported improvements in symptoms and quality of life in patients with Parkinson's disease (PD). Additionally, morphological brain changes after exercising were reported in PD animal models. However, these lifestyle-related changes were not evaluated in postmortem brain tissue. Objective: We aimed to evaluate, by immunohistochemistry, astrocytes, tyrosine hydroxylase (TH) and structural proteins expression (neurofilaments and microtubules — MAP2) changes in postmortem brain samples of individuals with Lewy body pathology. Methods: Braak PD stage≥III samples, classified by neuropathology analysis, from The Biobank for Aging Studies were classified into active (n=12) and non-active (n=12) groups, according to physical activity lifestyle, and paired by age, sex and Braak staging. Substantia nigra and basal ganglia were evaluated. Results: Groups were not different in terms of age or gender and had similar PD neuropathological burden (p=1.00). We observed higher TH expression in the active group in the substantia nigra and the basal ganglia (p=0.04). Astrocytes was greater in the non-active subjects in the midbrain (p=0.03) and basal ganglia (p=0.0004). MAP2 levels were higher for non-active participants in the basal ganglia (p=0.003) and similar between groups in the substantia nigra (p=0.46). Neurofilament levels for non-active participants were higher in the substantia nigra (p=0.006) but not in the basal ganglia (p=0.24). Conclusion: Active lifestyle seems to promote positive effects on brain by maintaining dopamine synthesis and structural protein expression in the nigrostriatal system and decrease astrogliosis in subjects with the same PD neuropathology burden.

RESUMO Objetivo: Avaliar pacientes idosos em um serviço de geriatria, juntamente com as características sensitivas e sua associação com aspectos clínicos. Métodos: Este é um estudo longitudinal descritivo. Foram avaliados 36 sujeitos saudáveis de ambos os sexos. Os seguintes instrumentos e avaliações foram realizados: Avaliação clínica, Mini Exame de Estado Mental (Mini-Mental) e testes sensitivos quantitativos. Resultados: Durante o acompanhamento houve redução do volume corpuscular médio (VCM) em cada avaliação (P < 0,001) e aumento significativo das concentrações de hemoglobina corpuscular média (CHCM) (P < 0,001). Houve aumento dos limiares olfativos (p < 0,001), salgado (p = 0,024), azedo (p = 0,020), amargo (p = 0,001), frio face (p = 0,019), frio mão (p = 0,004), tato face (p < 0,001), tato mão (p = 0.012) e vibração face (p = 0,018). Morbidades prévias foram associadas às alterações de sensibilidade nos indivíduos desta amostra. Conclusão: Este estudo longitudinal sugere que a perda de sensibilidade no envelhecimento pode estar associada à presença de morbidades em idosos.

ABSTRACT Objective: To evaluate elderly patients in a geriatric service, along with their sensory characteristics and their association with clinical aspects. Methods: This was a descriptive longitudinal study. We enrolled 36 healthy participants of both sexes in this study. The following instruments were used and evaluations performed: clinical evaluation, Mini-Mental State Exam, and quantitative sensory testing. Results: During the follow-up, there was reduction of mean corpuscular volume at each evaluation (p < 0.001) and significant increase in mean corpuscular hemoglobin concentration (p < 0.001). There was an increase of the olfactory (p < 0.001), salty (p = 0.024), sour (p = 0.020), bitter (p = 0.001), facial cold (p = 0.019), hand cold (p = 0.004), facial tactile (p < 0.001), hand tactile (p = 0.012) and facial vibration (p = 0.018) thresholds. Previous existing morbidities were associated with sensitivity changes in the individuals in this sample. Conclusion: This longitudinal study suggests that the loss of sensitivity with aging may be associated with the presence of morbidities in elders.

RESUMO. Introdução: Diabetes mellitus é um fator de risco para a demência, especialmente para a demência vascular (DV), mas ainda não há consenso sobre diabetes como fator de risco para a doença de Alzheimer (DA) e outras causas de demência. Objetivo: Verificar a associação entre diabetes e demência e sua etiologia neuropatológica em um grande estudo de autópsia. Métodos: Os dados foram coletados do Banco de Encéfalos Humanos do Grupo de Estudos em Envelhecimento Cerebral da FMUSP entre 2004 e 2015. O diagnóstico de diabetes foi relatado por pelos parentes do falecido. A demência clínica foi estabelecida quando CDR ≥ 1 e IQCODE > 3,41. A etiologia da demência foi determinada pelo exame neuropatológico com imuno-histoquímica. A associação de diabetes com probabilidades de demência foi investigada usando regressão logística multivariada. Resultados: Foram incluídos 1.037 sujeitos, diabetes esteve presente em 279 participantes (27%). A frequência de diagnóstico de demência foi semelhante entre diabéticos (29%) e não diabéticos (27%). Não encontramos associação entre diabetes e demência (OR = 1,22; IC 95% = 0,81-1,82; p = 0,34) na análise multivariada. DA foi a principal causa de demência em ambos os grupos, DV foi a segunda causa em diabéticos. A frequência de outra demência mista foi a segunda causa de demência e mais frequente entre os não diabéticos (p = 0,03). Conclusão: A diabetes não foi associada à demência neste grande estudo clínico-patológico.

ABSTRACT. Background: Diabetes mellitus is a risk factor for dementia, especially for vascular dementia (VaD), but there is no consensus on diabetes as a risk factor for Alzheimer's disease (AD) and other causes of dementia. Objective: To explore the association between diabetes and the neuropathological etiology of dementia in a large autopsy study. Methods: Data were collected from the participants of the Brain Bank of the Brazilian Aging Brain Study Group between 2004 and 2015. Diagnosis of diabetes was reported by the deceased's next-of-kin. Clinical dementia was established when CDR ≥ 1 and IQCODE > 3.41. Dementia etiology was determined by neuropathological examination using immunohistochemistry. The association of diabetes with odds of dementia was investigated using multivariate logistic regression. Results: We included 1,037 subjects and diabetes was present in 279 participants (27%). The prevalence of dementia diagnosis was similar in diabetics (29%) and non-diabetics (27%). We found no association between diabetes and dementia (OR = 1.22; 95%CI = 0.81-1.82; p = 0.34) on the multivariate analysis. AD was the main cause of dementia in both groups, while VaD was the second-most-frequent cause in diabetics. Other mixed dementia was the second-most-common cause of dementia and more frequent among non-diabetics (p = 0.03). Conclusion: Diabetes was not associated with dementia in this large clinicopathological study.

OBJECTIVES: To describe and correlate tongue force and grip strength measures and to verify the association of these measures with water swallowing in different age groups. METHOD: Tongue force was evaluated using the Iowa Oral Performance Instrument and grip strength using the Hand Grip in 90 normal individuals, who were divided into three groups: young (18-39 years old), adult (40-59 years old) and elderly (above 60 years old) individuals. The time and number of swallows required for the continuous ingestion of 200 ml of water were also measured. RESULTS: A reduction in tongue force and grip strength, as well as an increase in the time required to drink 200 ml of water, were observed with increasing participant age. There was no difference in the number of swallows among the three groups. A correlation was observed between reductions in tongue force and grip strength in the groups of young and elderly individuals. CONCLUSION: There were differences in the measures of tongue force in young, adult and elderly individuals. Greater variations within these differences were observed when repeated movements were performed; in addition, a decrease in strength was associated with an increase in age. The decrease in tongue force among the elderly was offset by the increase in time needed to swallow the liquid. There was an association between the measures of tongue force and grip strength in the different age groups. The results of this study can be applied clinically and may act as a basis for guidelines in healthy or vulnerable elderly populations.

OBJECTIVE:Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC) to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior).METHODS:We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique.RESULTS:The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3%) had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior). The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L) and FVC (2.0±0.7 L) with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p= 0.59) for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed.CONCLUSIONS:Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery.

Objective To evaluate the learning effect of computerized cognitive testing in the elderly.Methods Cross-sectional study with 20 elderly, 10 women and 10 men, with average age of 77.5 (±4.28) years. The volunteers performed two series of computerized cognitive tests in sequence and their results were compared. The applied tests were: Trail Making A and B, Spatial Recognition, Go/No Go, Memory Span, Pattern Recognition Memory and Reverse Span.Results Based on the comparison of the results, learning effects were observed only in the Trail Making A test (p=0.019). Other tests performed presented no significant performance improvements. There was no correlation between learning effect and age (p=0.337) and education (p=0.362), as well as differences between genders (p=0.465).Conclusion The computerized cognitive tests repeated immediately afterwards, for elderly, revealed no change in their performance, with the exception of the Trail Making test, demonstrating high clinical applicability, even in short intervals.

RESUMO Com o envelhecimento da população aumenta a possibilidade de ocorrência de um declínio cognitivo. Diversas formas de intervenção buscam amenizar ou reverter este prejuízo. O emprego de testes computadorizados auxilia na detecção dos efeitos das intervenções nas funções cognitivas dos idosos. O objetivo desta revisão foi o de analisar os estudos que utilizaram testes cognitivos computadorizados para verificar o efeito de intervenções na população idosa, descrevendo as baterias e testes empregados, as populações analisadas e o relato dos autores sobre limitações ou facilidades do emprego destes testes na população. Foi revista a base de dados PubMed com os descritores: teste cognitivo computadorizado e idoso. Encontramos 530 estudos e, pela leitura dos resumos, selecionamos 32 pela relevância com o tema. Estes utilizaram 19 tipos de testes ou baterias computadorizadas para avaliar as intervenções, que na sua maioria foram medicamentosas. Não houve relato de limitações na utilização dos testes computadorizados, sugerindo que a aplicação desta forma de avaliação tenha boa aplicabilidade, sensibilidade e pouco ou nenhum efeito de aprendizagem nesta população.

ABSTRACT With the aging of the population, the possibility of the occurrence of cognitive decline rises. A number of types of intervention seek to attenuate or reverse this impairment. The use of computerized tests helps quantify the effects of interventions on cognitive function in the elderly. The objective of the present review was to analyze studies that have utilized computerized cognitive tests to determine the effects of interventions in the elderly population, describing the batteries and tests employed, the populations studied and reports by authors on the limitations or benefits of employing these tests in older adults. The review was performed on the PubMed database using the descriptors: cognitive computerized test and elderly. We retrieved 530 studies and, following analysis of their abstracts, selected 32 relevant to the subject. The studies utilized 19 different types of computerized tests and batteries to assess the interventions, which were predominantly drug trials. There were no reports on limitations in the use of the computerized tests, suggesting this type of intervention had good applicability, sensitivity, and little or no practice effects in this population.

OBJETIVO: Comparar os efeitos das atividades físicas resistida e aeróbia sobre a aptidão física e funcionalidade de idosos em dois programas de atividade supervisionada: exercícios resistidos e caminhada. MÉTODOS: Ensaio clínico, randomizado, prospectivo, com idosos sedentários, sem contraindicações para atividade física, distribuídos em dois grupos: o Grupo Resistido realizou 6 exercícios por treino, 2 vezes por semana e o Grupo Aeróbio realizou atividade por 30 minutos, 2 vezes por semana. A avaliação funcional (tempo 0,6 e 12 meses) foi realizada pelos seguintes parâmetros: Short Physical Performance Battery (tempo de sentar/levantar, velocidade da marcha e equilíbrio), flexibilidade, teste de caminhada de 6 minutos. Foram randomizados 96 participantes, 46 no Grupo Resistido e 50 no Grupo Aeróbio. No resistido, 46 compareceram na primeira avaliação e 20 permaneceram até a terceira. No aeróbio, 50 compareceram na primeira avaliação e 12 permaneceram até a terceira. RESULTADOS: A média da idade dos pacientes no Grupo Resistido foi de 68,8 anos e de 69,1 no Grupo Aeróbio. O primeiro apresentou melhora no sentar/levantar (p=0,022), no equilíbrio com pés seguidos (p=0,039) e enfileirados (p=0,001). No segundo, houve diferença estatística na velocidade, equilíbrio com pés seguidos e enfileirados (p=0,008, p=0,02 e p=0,043, respectivamente). Quanto à flexibilidade, o Grupo Resistido apresentou melhora (p=0,001), enquanto no Aeróbio não houve diferença significativa (p=0,359). No teste de caminhada de 6 minutos, ambos melhoraram, mas apenas o Grupo Aeróbio com significância (p=0,033). CONCLUSÃO: Ambos os grupos apresentaram melhora na aptidão física. Não houve diferença estatística quando comparados os grupos em relação ao Short Physical Performance Battery, à flexibilidade e à caminhada de 6 minutos na amostra estudada.

OBJECTIVE: To compare the effects of physical fitness and function on older adults in two programs of supervised exercise activity: resistance training and aerobic exercise. METHODS: This study is a randomized, prospective clinical trial composed of sedentary elderly people who did not have contraindications to exercise. Participants were divided into two groups: group one performed 6 exercises of resistance training twice a week, and group two participated in walking activity for 30 minutes twice a week. Functional assessment (time 0,6 and 12 months) was measured by the Short Physical Performance Battery (time to sit or stand, gait speed, and balance), flexibility test, and the six-minute walking test. We randomly selected 96 patients: 46 in the Resistance Training Group and 50 in the Aerobic Exercise Group. In the Resistance Training Group, 46 attended the first assessment and 20 attended until the third section. In the Aerobic Exercise Group, 50 attended the first assessment and 12 attended until the third assessment. RESULTS: Mean age was 68.8 years in the Resistance Training Group and 69.1 years in the Aerobic Exercise Group. The Resistance Training Group showed improvement in the sit/stand (p=0.022), balance with feet in a row (p=0.039) and queued (p=0.001). The second showed a statistical difference in speed and balance with the feet lined up and the feet together (p=0.008; p=0.02; and p=0.043, respectively). Concerning flexibility, the Resistance Training Group had improvement (p=0.001), whereas in the Aerobic Exercise Group, no significant difference was seen (p=0.359). Both groups had improvement in the six-minute walking test, but no significant improvement was seen in the Aerobic Exercise Group (p=0.033). CONCLUSION: Both groups showed improvement in physical fitness. No statistical difference was seen when groups was compared in the short physical performance battery, flexibility, and six-minute walking test.

OBJETIVO: Avaliar a contribuição da ultrassonografia no estudo das alterações histopatológicas encontradas na hepatite crônica pelo vírus C, com ênfase para a esteatose hepática. MATERIAIS E MÉTODOS: Foram comparados os resultados dos exames ultrassonográficos do fígado de 192 pacientes portadores de hepatite crônica pelo vírus C, com os achados histopatológicos dos fragmentos obtidos por biópsia hepática. Todos os exames ultrassonográficos obedeceram a um mesmo protocolo, sendo analisados os seguintes critérios: ecogenicidade, ecotextura e atenuação. Os pacientes foram agrupados considerando-se os com alterações ultrassonográficas e os sem alterações ultrassonográficas, sendo comparados com as alterações histopatológicas presentes. RESULTADOS: Entre as alterações histopatológicas presentes, apenas os graus 0 e 3 de alteração arquitetural e a esteatose hepática apresentaram diferença estatística significante entre os dois grupos. Dentre os critérios ultrassonográficos avaliados, a atenuação foi o que apresentou melhor correlação com a esteatose hepática. CONCLUSÃO: Os resultados do trabalho demonstraram que, em pacientes com hepatite crônica pelo vírus C, a ultrassonografia apresentou limitações à caracterização das alterações histopatológicas, apresentando concordância regular com o diagnóstico de esteatose hepática. Destaca-se a capacidade do método em mostrar a probabilidade de inexistência de esteatose hepática, tendo em vista a especificidade de 77,9% e o valor preditivo negativo de 95,5%.

OBJECTIVE: To evaluate the role of ultrasonography in the assessment of histopathological changes in patients with chronic hepatitis C, with emphasis on hepatic steatosis. MATERIALS AND METHODS: Liver ultrasonography results were compared with histopathological findings of liver biopsy of 192 patients with chronic hepatitis C virus infection. All the US examinations followed a single protocol, analyzing the following aspects: echogenicity, echotexture and attenuation. The patients sample was divided into two groups as follows: patients with sonographic changes and patients with no sonographic changes. Sonographic findings of both groups were compared with histopathological findings after liver biopsy. RESULTS: Statistically significant intergroup differences were observed just regarding architectural changes grades 0 and 3 and hepatic steatosis. Attenuation was the sonographic criterion that was best correlated with hepatic steatosis. CONCLUSION: The results of the present study demonstrate that, in patients with chronic hepatitis C, ultrasonography has limitations in the characterization of histopathological changes, with an intermediate rate of agreement with the diagnosis of hepatic steatosis. Considering the specificity of 77.9% and the negative predictive value of 95.5%, the authors highlight the capacity of the method to demonstrate the probability of absence of hepatic steatosis.

RESUMO Objetivo: Determinar a prevalência de medicamentos potencialmente inapropriados em idosos ambulatoriais; identificar os mais comumente envolvidos; e verificar se a idade e o sexo do paciente, além do número de medicamentos, estão relacionados à prescrição de medicamentos potencialmente inapropriados. Métodos: Foram coletadas prescrições de 1.800 pacientes idosos (≥ 60 anos) em banco de dados. As prescrições foram realizadas por clínicos gerais de hospital universitário de atenção terciária em São Paulo entre Fevereiro e Maio de 2008; foi considerada apenas uma prescrição por paciente. As prescrições foram divididas de acordo com o sexo e faixa etária (60-69; 70-79 e ≥ 80). Os critérios de Beers versão 2003 foram utilizados para a avaliação de medicamentos potencialmente inapropriados. Resultados: A maior parte da casuística foi composta por mulheres (66,6%) e a média de idade foi de 71,3 anos. A prevalência média de prescrição de MPIs foi de 37,6%, sendo que a faixa etária de 60-69 anos apresentou a maior prevalência (49,9%). Os medicamentos potencialmente inapropriados mais prescritos para as mulheres foram o carisoprodol, a amitriptilina e a fluoxetina e, para os homens, foram a amitriptilina, o carisoprodol, a fluoxetina e a clonidina. O sexo feminino (p < 0,001; RC = 2,0) e o número de medicamentos prescritos (p < 0,001) foram associados à prescrição de medicamentos potencialmente inapropriados. A chance de prescrição de um medicamentos potencialmente inapropriados foi menor em pacientes com ≥ 80 anos (RC = 0,7). A média de medicamentos prescritos foi 7,1, considerando ambos os sexos e todas as faixas etárias. A média do número de medicamentos por paciente foi maior no sexo feminino (p < 0,001), sendo que esse resultado não dependeu da faixa etária (p = 0,285). Conclusão: A prevalência de medicamentos potencialmente inapropriados encontrada foi semelhante ao relatado na literatura e está correlacionada ao sexo feminino. A chance de prescrição de medicamentos potencialmente inapropriados foi menor em pacientes com ≥ 80 anos e observou-se que é maior à medida que aumenta o número de medicamentos prescritos (≥ 5).

ABSTRACT Objective: To establish the prevalence of potentially inappropriate medications prescribed for elderly patients, to identify the most commonly involved drugs, and to investigate whether age, sex and number of medications were related with the prescription of these drugs. Methods: Prescriptions for 1,800 elderly patients (≥ 60 years) were gathered from a database. These prescriptions were written by general physicians at a tertiary level university hospital in the city of Sao Paulo, Brazil, from February to May 2008. Only one prescription per patient was considered. The prescriptions were classified according to sex and age (60-69, 70-79 and ≥ 80). The Beers criteria (2003 version) were used to evaluate potentially inappropriate medications. Results: Most of the sample comprised women (66.6%) with a mean age of 71.3 years. The mean prevalence of potentially inappropriate medication prescriptions was 37.6%. The 60-69 age group presented the highest prevalence (49.9%). The most frequently prescribed potentially inappropriate medications to women were carisoprodol, amitriptyline, and fluoxetine; amitriptyline, carisoprodol, fluoxetine and clonidine were prescribed more often to men. The female sex (p<0.001; OR=2.0) and number of medications prescribed (p<0.001) were associated with prescription of potentially inappropriate medications. The chance of having a prescription of these drugs was lower among patients aged over 80 years (OR=0.7). The mean number of prescribed medications for both sexes and all age groups was 7.1. The mean number of medications per patient was higher among females (p<0.001); this result was not age-dependent (p=0.285). Conclusion: The prevalence of potentially inappropriate medications was similar to previously reported values in the literature and was correlated with the female sex. The chance of having a potentially inappropriate medication prescription was lower among patients aged over 80 years. The chance of having a potentially inappropriate medications prescription increased proportionally with the number of medications prescribed (≥ 5).
