Usability and acceptability of internet-based interventions for family carers of people living with dementia: systematic review.

Objectives: Internet-based interventions can help carers of people living with dementia to cope with care-related challenges and can help improve their wellbeing. This systematic review aimed at investigating the criteria of usability and acceptability of self-guided internet-based interventions for family carers of people living with dementia. Method: Searches were conducted on PubMed, Virtual Health Library Regional Portal (Americas), MEDLINE, PsycINFO, Scopus, and Cochrane. Studies published up to December 2019, in English, Portuguese, or Spanish, were eligible. We followed the definition/criteria from ISO ISO-9241-11 for usability (efficiency, effectiveness, and satisfaction) and acceptability (barriers for using and utility). Methodological quality was evaluated using specific tools according to each study design. Results: Ten studies were included, all of which had high methodological quality. Carers of people living with dementia indicated that internet-based interventions were mostly effective, efficient, and satisfactory. They considered these to be informative, relevant, and functional, highlighting the utility and intention of using the resource in the future. The high heterogeneity in the terms and methods used to evaluate usability and acceptability hindered cross-study comparisons, however internet-based interventions were considered useful and acceptable by most carers. Conclusion: Future research should consider expanding the criteria of usability and acceptability to better reflect the needs of this population.

Empathy Training for Caregivers of Older People: A Systematic Review.

OBJECTIVES: To identify empathy training models and the effects on psychological concerns in paid and unpaid caregivers of older people. METHODS: A systematic review was conducted. Searches for relevant articles were performed in the Embase, LILACS, PsycInfo, Pubmed, Scopus and Web of Science databases using the following search strategy: "Empathy AND (Education OR Training OR Intervention) AND Caregiver." No restrictions were imposed regarding language or year of publication. RESULTS: Empathy training for caregivers of older people were performed in six studies, three of which identified a significant increase in empathy levels and consequent reduction in psychological concerns. Empathy training focused on aspects of empathy and/or the caregiver had significant effects on the outcome variables. Moreover, training conducted online, by telephone and/or in person can generate satisfactory results. The other three studies that conducted training with a focus on aspects of dementia and/or old age did not present any effect on the outcome variables. CONCLUSIONS: Empathy training for caregivers of older people can increase levels of this ability, especially in the cognitive domain, as well as diminish psychological concerns caused by the negative impact of providing care. CLINICAL IMPLICATIONS: Empathy training directed at empathic abilities and/or aspects of providing care can be effective at increasing levels of this ability. Moreover, training in different care contexts can minimize the negative impacts of providing care.

Elderly caregivers living in urban, rural and high social vulnerability contexts.

OBJECTIVE Comparing the differences in the sociodemographic, care and health profiles of elderly caregivers of the elderly living in urban, rural, and high social vulnerability contexts. METHOD A cross-sectional study developed with elderly caregivers enrolled in the Family Health Units of a municipality in the interior of São Paulo. Household interviews and evaluations were conducted on: Activities of Daily Living (ADL), self-reported pain, frailty, cognition, life satisfaction, family functionality, burden, stress and hope. RESULTS A total of 343 elderly caregivers of elderly individuals participated in the study, of which 55.1% lived in an urban context, 23.6% in rural areas, and 21.3% in a context of high social vulnerability. The majority of elderly caregivers were women across the three contexts, with a median age of 67 years and caring for their spouse. Caregivers from regions of high social vulnerability had lower education level, received less emotional and material help to care, were less satisfied with life, more fragile, in more cognitive decline, had worse family functionality and a lower level of hope when compared to caregivers of urban and rural contexts (p≤0.05). However, caregivers from areas of high vulnerability were more independent for ADL. CONCLUSION Professionals working in Primary Care should consider these differences when planning interventions aimed at the specific group of caregivers.

Translation and cultural adaptation of the Positive Aspects of Caregiving Scale for caregivers of people living with dementia in Brazilian context: a methodological study.

BACKGROUND: The Positive Aspects of Caregiving (PAC) scale is used to assess psychosocial benefits provided to caregivers by the task of caring. The PAC scale consists of nine items, assessed using a five-point Likert scale, with higher values indicating greater positive perceptions and gains from the caregiving experience. OBJECTIVE: To translate and culturally adapt the PAC scale for informal Brazilian caregivers of people with dementia. DESIGN AND SETTING: A methodological study was conducted at the Federal University of São Carlos. METHODS: The following stages were carried out: Translation; Synthesis of the translations; Back-translation; Evaluation by an experts' committee; and Pre-test. RESULTS: Two independent professionals translated the PAC scale. The consensus version was obtained by merging both translations, which were back-translated into English by a third translator. The expert committee comprised three specialists in the area and project researchers. All scale items presented a Content Validity Index of 1 (CVI = 1.0), and thus remained in the pre-final version of the instrument. The instrument was pre-tested with seven caregivers of people with dementia, the majority of whom were women (57.1%), with a degree of kinship corresponding to sons/daughters (57.1%) and an average age of 55.2 (± 4.1) years. The caregivers considered it clear and understandable and made no suggestions for changes. CONCLUSION: The PAC scale was translated and culturally adapted for use by informal caregivers of people with dementia in Brazil. However, a psychometric analysis of the instrument is necessary to provide normative data for this population group.

Cognitive performance, burden and stress in aged caregivers of older adults with and without cognitive impairment.

There is an increasing number of aged people who provide care for other older people. Commonly existing burden and stress can change the forms of cognitive performance depending on the context of the aged caregivers. Objective: To compare the cognitive performance, burden and stress of aged caregivers of older adults with and without signs of cognitive impairment. Methods: A cross-sectional and quantitative study conducted with 205 aged caregivers of older adults with signs of cognitive impairment and 113 aged caregivers of older adults without signs of cognitive impairment treated in Primary Health Care. They were evaluated for sociodemographic characteristics, cognition, burden, and stress. Descriptive (Kolmogorov-Smirnov test) and comparative (Student's t-test and Pearson's χ² test) analyses were performed. Results: Aged caregivers of older adults with signs of cognitive impairment were older, had lower schooling levels, and a higher percentage of daily care hours compared to the aged caregivers of older adults without signs of cognitive impairment. Regarding cognitive performance, the means were lower for all domains. In addition, this same group had higher scores, with a statistically significant difference for perceived stress and burden. Conclusion: Aged caregivers of older adults with signs of cognitive impairment showed lower cognitive performance, as well as higher burden and stress levels. These findings guide the planning of interventions with aged caregivers in the Primary Health Care.

Nota-se um crescente número de idosos que prestam cuidados a outros idosos. A sobrecarga e o estresse comumente existentes podem afetar de formas diferentes o desempenho cognitivo, a depender do contexto desses idosos cuidadores. Objetivo: Comparar o desempenho cognitivo, a sobrecarga e o estresse de idosos cuidadores de idosos com e sem indícios de alterações cognitivas. Métodos: Estudo transversal e quantitativo realizado com 205 idosos cuidadores de idosos com indícios de alterações cognitivas e 113 idosos cuidadores de idosos sem indícios de alterações cognitivas atendidos na Atenção Primária à Saúde. Eles foram avaliados quanto às características sociodemográficas, cognição, sobrecarga e estresse. Análises descritivas (teste de Kolmogorov-Smirnov) e comparativas foram realizadas (teste t de Student e χ² de Pearson). Resultados: Os idosos cuidadores de idosos com indícios de alterações cognitivas eram mais velhos, com menor escolaridade e maior percentual de horas diárias de cuidado em comparação aos idosos cuidadores de idosos sem indícios de alterações cognitivas. Já quanto ao desempenho cognitivo, as médias foram inferiores para todos os domínios. Além disso, esse mesmo grupo apresentou maior pontuação, com diferença estatisticamente significante, para o estresse percebido e para a sobrecarga. Conclusão: Os cuidadores de idosos com indícios apresentaram menor desempenho cognitivo e maiores níveis de sobrecarga e estresse. Tais achados norteiam o planejamento de intervenções voltadas aos idosos cuidadores na Atenção Primaria à Saúde.

Sociodemographic, clinical, and psychosocial factors associated with burden in older caregivers: a cross-sectional study.

The task of caring can negatively affect the physical and mental health; therefore, it is important to understand which factors are associated with burden in older caregivers of older adults. Objective: This study aimed to explore sociodemographic, clinical, and psychosocial factors associated with burden in older caregivers of older adults. Methods: This is a cross-sectional study developed with 349 older caregivers who were registered at a Family Health Unit of a city in the state of São Paulo, Brazil. Household interviews were conducted and data were collected on the sociodemographic (profile, family income), clinical (self-reported pain, sleep, frailty), and psychosocial (burden, family functioning, depressive symptoms, stress) characteristics of the caregivers as well as dependence on activities of daily living and cognition in the care recipients. Results: Women predominated in the sample (76.5%) and mean age was 69.5 years. The mean burden score was 18.06 points, with 47.9% above the cutoff of 16 points, denoting excessive burden. The bivariate model revealed associations between burden and financial insufficiency, family dysfunction, difficulty sleeping, pain, perceived stress, depressive symptoms, frailty, and multimorbidity among the caregivers as well as worse functional and cognitive performance in the care recipients. The controlled model revealed an association between burden and depressive symptoms (ß=16.75; 95%CI 1.80-31.68). Conclusions: We identified an association between burden and depressive symptoms, underscoring the need for the planning and implementation of specific actions directed at caregivers in order to minimize the impact on health and to improve the quality of life.

A tarefa de cuidar pode afetar negativamente a saúde física e mental, sendo importante compreender quais os fatores associados à sobrecarga em idosos cuidadores de idosos. Objetivo: Explorar os fatores sociodemográficos, clínicos e psicossociais associados à sobrecarga em idosos cuidadores de idosos. Métodos: Estudo transversal desenvolvido com 349 idosos cuidadores cadastrados nas unidades de Saúde da Família de um município do interior paulista. Foram realizadas entrevistas domiciliares e coletados dados sobre as informações sociodemográficas (perfil, renda familiar), clínicas (dor autorrelatada, sono, fragilidade) e psicossociais (sobrecarga, funcionalidade familiar, sintomas depressivos, estresse) do cuidador, bem como dados de funcionalidade e cognição dos receptores de cuidados. Resultados: Houve prevalência do sexo feminino (76,5%), com média de idade de 69,5 anos. A média do escore da sobrecarga foi 18,06 pontos, com 47,9% dos idosos cuidadores acima da nota de corte de 16 pontos. O modelo univariado revelou associação entre sobrecarga e percepção de insuficiência financeira, disfunção familiar, dificuldade de dormir, dor, estresse percebido, sintomas depressivos, fragilidade e multimorbidade, além de pior desempenho funcional e cognitivo dos idosos receptores de cuidados. No modelo controlado houve associação entre sobrecarga e sintomas de depressão (ß=16,75; intervalo de confiança ­ IC95% 1,80­31,68). Conclusão: Identificamos associação entre sobrecarga e sintomas depressivos, de modo que é necessário planejar e implementar cuidados específicos a fim de minimizar o impacto na saúde dos cuidadores e favorecer a qualidade de vida.

Performance of older adults in a digital change detection task: The role of heterogeneous education.

The influence of education on traditional paper-and-pen cognitive assessments is widely reported. However, a minimal amount of evidence is available regarding the role of education in digital tasks. This study aimed to compare the performance of older adults with different educational attainment in a digital change detection task, as well as to relate their performance on the digital task and traditional paper-based tests. Participants (n = 180) were recruited in primary health care settings from a countryside city in the state of Sao Paulo-Brazil and were assigned to three different groups according to their educational background. Traditional paper-based neuropsychological instruments (i.e., ACE-R, Digit Span, Bells test) were used in addition to a digital change detection task. There was no difference in reaction time on the change detection task between the groups; however, participants with higher educational levels performed better than illiterates or lower education groups. The digital test was correlated to ACE-R total score as well as to its language domain. Our results suggested that the performance in the digital task was different for older adults with heterogeneous educational attainment. Technology is a promising pathway in cognitive assessment, and education should be considered in the interpretation of the results.

Depressive symptoms and sleep in aged caregivers in a context of high social vulnerability.

OBJECTIVE: To evaluate the relationship between depressive symptoms and sleep quality in aged caregivers of elderly people, in a context of high social vulnerability. METHODS: A Cross-sectional study conducted between July 2019 and March 2020 with 65 aged caregivers of elderly people that were treated in five Family Heath Units from São Carlos, São Paulo. Instruments to characterize the caregivers and to evaluate the depressive symptoms and sleep quality were used in data collection. The Kruskal Wallis and Spearman Correlation tests were adopted. RESULTS: 73.9% of the caregivers presented poor sleep quality and 69.2% did not have depressive symptoms. In the caregivers with severe depressive symptoms, the mean sleep quality score was 11.4; in those with mild depressive symptoms, it was 9.0; and in those without depressive symptoms, it was 6.4. There was a direct and moderate correlation between sleep quality and depressive symptoms. CONCLUSION: There is a relationship between depressive symptoms and sleep quality in aged caregivers.

Social support perceived by elderly people in social vulnerability according to family functionality: a cross-sectional study.

OBJECTIVE: To compare the social support as perceived by elderly persons in a context of social vulnerability according to family functionality. METHOD: A cross-sectional study using a quantitative approach, carried out in São Carlos-SP, with 123 elderly people living in a context of high social vulnerability. The sample was divided into two groups: good family functionality and moderate/severe family dysfunction. Data was collected on sociodemographic characteristics, family functionality (Family APGAR) and social support (Medical Outcomes Study Social Support Scale). The Mann-Whitney, Chi-square and Fisher's exact statistical tests were used. RESULTS: There was a statistically significant difference between social support and family functionality (p < 0.05). The group with good family functionality obtained higher median social support scores: affective 100.00; material 95.00; information 90.00; emotional 90.00; positive social interaction 85.00; when compared to the group with moderate/severe family dysfunction: affective 86.67; material 87.50; information 70.00; emotional 65.00; positive social interaction 65.00. CONCLUSION: Elderly persons living in dysfunctional families have less perceived social support when compared to those living in families with good family functionality.

Efficacy of iSupport-Brasil for unpaid caregivers of people living with dementia: protocol for a randomized and controlled clinical trial.

Unpaid caregivers of people living with dementia tend to suffer mental health problems as a result of the negative effects associated with the care tasks. Thus, psychosocial interventions for this population group are necessary. iSupport is an online support program for caregivers that was created by the World Health Organization. Objective: To describe the design of a randomized clinical trial to measure the efficacy of the iSupport-Brasil version on caregivers' mental health and well-being. Methods: The participants will be randomized into Intervention Group (IG) (n=195) and Control Group (CG) (n=195). For three months, the IG will access the iSupport-Brasil platform, the CG will enter the electronic page of the Brazilian Alzheimer's Association, and both groups will be emailed the preliminary version of the "Guia de cuidados para a pessoa idosa" e-book (a guide to providing care to the elderly) from the Ministry of Health. The data will be collected at three moments: baseline, and three and six months after the beginning of the intervention. Results: It is expected that it will be possible to provide diverse validity evidence about iSupport-Brasil as an online and free intervention alternative, as a preventive means and as a way to promote mental health among caregivers of people living with dementia. Conclusion: Through the evaluation protocol of this randomized clinical trial on the effects of the iSupport-Brasil program, it may become a reference for countries that plan to adapt and improve the iSupport program using digital health solutions.

Accumulated cognitive impairment, frailty, burden, and perceived stress and the risk of hospitalization and mortality in older caregivers.

Combination of cognitive impairment, frailty, perceived stress, and excessive burden poses a risk to the health of caregivers. Objectives: This study aimed to investigate the influence of the combination of these conditions on the occurrence of hospitalizations and deaths among older caregivers in a 4-year follow-up period. Methods: This is a longitudinal study in the communities with 351 older caregivers who underwent gerontological and geriatric evaluations in 2014 and completed cognitive (Mini-Mental State Examination), physical frailty (Cardiovascular Health Study criteria), perceived stress (Perceived Stress Scale), and care burden (Zarit Burden Interview) assessments. In 2018, data on hospitalization and mortality were collected. Results: As a result, 32 (12.6%) caregivers had deceased. Among the 228 survived caregivers who were reevaluated, 24% reported using hospital services in the previous year. Mean length of hospital stay was 3 days (range: 1-22 days). Hospitalization was associated with cognitive impairment co-occurring with frailty (p=0.05), stress (p=0.03), burden (p=0.01), and frailty co-occurring with stress (p=0.04). Considering singular effects, the mortality rate (33.3%) was higher among frail caregivers, followed by those with cognitive impairment (23.1%) and a high level of perceived stress (20.4%). Considering accumulative conditions, mortality rate (43.8%) was higher among frail older caregivers with cognitive impairment, followed by those with a high level of perceived stress and cognitive impairment (32.4%). Conclusions: The investigation of accumulated effects is important to the identification of potentially vulnerable older caregivers as well as the management and monitoring of the care, health, and independence of those who provide care for other older adults.

Comprometimento cognitivo, fragilidade, estresse e sobrecarga, combinados, podem representar maior risco à saúde dos cuidadores. Objetivos: O objetivo do estudo foi analisar a influência da combinação dessas condições na ocorrência de hospitalizações e óbitos entre idosos cuidadores em um período de seguimento de quatro anos. Métodos: Estudo longitudinal na comunidade, com 351 idosos cuidadores submetidos a avaliação gerontológico-geriátrica em 2014, composta de avaliação da cognição (Miniexame do Estado Mental), fragilidade física (critérios do Cardiovascular Health Study), estresse percebido (Escala de Estresse Percebido) e sobrecarga do cuidado (Zarit Burden Interview). Em 2018, foram coletados dados sobre admissão hospitalar e mortalidade. Resultados: Trinta e três (12,6%) cuidadores faleceram. Entre os 228 cuidadores sobreviventes, 24% relataram ter utilizado os serviços hospitalares no ano anterior. A hospitalização foi associada com comprometimento cognitivo coocorrendo com fragilidade (p=0,05), estresse (p=0,03) e sobrecarga (p=0,01), bem como fragilidade coocorrendo com estresse (p=0,04). Considerando-se os efeitos singulares, a taxa de mortalidade foi maior entre cuidadores frágeis (33,3%), seguidos daqueles com comprometimento cognitivo (23,1%) e alto nível de percepção de estresse (20,4%). Considerando-se as condições acumuladas, a mortalidade foi maior entre cuidadores idosos frágeis com comprometimento cognitivo (43,8%), seguidos por aqueles com alto nível de estresse percebido e comprometimento cognitivo (32,4%). Conclusões: A investigação dos efeitos acumulados é importante para a identificação de cuidadores de idosos potencialmente vulneráveis, bem como para o gerenciamento e o monitoramento do cuidado, para a saúde e a independência daqueles que cuidam de outros idosos.

Association between frailty and depression among hemodialysis patients: a cross-sectional study.

BACKGROUND: Frailty is consensually understood to be a clinical syndrome in which minimal stressors can lead to negative outcomes such as hospitalization, early institutionalization, falls, functional loss and death. Frailty is more prevalent among patients with chronic kidney disease (CKD), and those on dialysis are the frailest. Depression contributes towards putting patients with CKD into the frailty cycle. OBJECTIVE: To assess frailty and its relationship with depression among patients with CKD undergoing hemodialysis. DESIGN AND SETTING: Observational and quantitative cross-sectional study conducted in a renal therapy unit, located in the interior of the state of São Paulo, Brazil. METHODS: This investigation took place in 2019, among 80 patients. The following instruments were applied: a sociodemographic, economic and health condition characterization and the Subjective Frailty Assessment (SFA) and Patient Health Questionnaire-9 (PHQ-9). RESULTS: Among the patients, there was higher prevalence of females, individuals with a steady partner and retirees, and their mean age was 59.63 (± 15.14) years. There was high prevalence of physical frailty (73.8%) and depression (93.7%). Depression was associated with frailty, such that patients with depression were 9.8 times more likely to be frail than were patients without depression (odds ratio, OR = 9.80; 95% confidence interval, CI, 1.93-49.79). CONCLUSION: Based on the proposed objective and the results achieved, it can be concluded that depression was associated with the presence of frailty among patients with CKD on hemodialysis.

The association between language and recognition of facial emotional expressions in elderly individuals. / Associação entre linguagem e o reconhecimento de expressões faciais de emoções em idosos.

PURPOSE: To check the association between a good performance of language and the recognition of facial emotional expressions in elderly individuals. METHODS: Transversal study performed with 118 elderly individuals from the primary care services of health of a city in the state of São Paulo. Sociodemographic data were collected, regarding the performance of language through the domain of Addenbrooke Cognitive Examination - Revised and Recognition of Facial Emotional Expressions. The sample was divided in thirds according to the performance of language: T1 = the best, T2 = average, and T3 = the worst. The groups T1xT3 were compared regarding the performance of recognition of facial expressions of anger, disgust, fear, happiness, sadness, and surprise, and for the intensities of 40%, 60%, 80%, and 100%. The association of independent variables over the performance of language was analyzed through logistic regression. The multivariate model was built from the results of the univariate analyses and has included the continuous variables by emotion and by intensity. Age and schooling associated to the performance of language in the univariate model were included in the multivariate model in order to adjust association analyses. RESULTS: The sample was mainly female (84.7%), with an average age of 70.5 years old, and 3.5 schooling years. The variables associated to the best performance of language in comparative analysis of T1 and T3 were: surprise (OR = 1.485, IC 95% 1.194 - 1.846), and disgust (OR = 1.143, IC 95% 1.005 - 1.300). CONCLUSION: The recognition of facial emotional expressions of surprise and disgust were shown as important factors associated to the good performance of language.

As variáveis ​​associadas ao melhor desempenho de linguagem na análise comparativa de T1 e T3 foram: surpresa (OR= 1,485, IC 95% 1,194 ­ 1,846) e nojo (OR= 1,143, IC 95% 1,005 ­ 1,300). CONCLUSÃO: O reconhecimento de expressões faciais das emoções surpresa e nojo mostraram-se importantes fatores associados ao bom desempenho da linguagem.

Correlation of family functionality and burden of informal caregivers of hospitalized older adults.

AIM: to analyze the relationship between family functionality and burden of informal caregivers of hospitalized older people. METHODS: this is a cross-sectional study conducted with 98 informal caregivers of hospitalized older people in an inpatient unit of a large hospital in São Carlos, São Paulo. For data collection were used questionnaires to sociodemographic and care context characterization, to evaluate burden and family functionality. Descriptive analyzes and Spearman's correlation coefficient were used. RESULTS: female caregivers predominated, who took care of their parents and had no training. Approximately 59.8% of caregivers had good family functionality and 49.5% scored for mild to moderate burden. There was a negative correlation, moderate magnitude, between family functionality and burden (p<0,001). The higher the burden score, the lower the family functionality score and vice versa. CONCLUSION: caregivers with high burden had worse family functionality. Therefore, nurses need to identify such conditions early and implement assertive interventions so that the family functions as a therapeutic resource.

ISupport-Brasil: Preliminary results of the usability and acceptability assessment by caregivers of people who have dementia.

Objective: To assess usability and acceptability of iSupport-Brasil (iSupport-BR) to virtually support family caregivers of people who have dementia. Materials and methods: In the first stage, nine caregivers/former caregivers assessed the interface of the platform that hosts iSupport-BR. In the second stage, 10 caregivers assessed acceptability of the platform and answered the System Usability Scale (SUS), which varies from 0 to 100 points. A descriptive analysis of the quantitative data was performed, as well as a thematic analysis on the open questions. All the ethical aspects were respected. Results: The results of the first stage indicated a user-friendly interface of the system and relevant content of the program, with 55.6 and 77.8% of the participants assigning the maximum grade to these questions, respectively. Of the five possible points, the system's mean score was 3.7. In Stage 2, 80% of the caregivers rated the program as very useful and 100% would recommend it to other caregivers. Perception of the program's usability by the SUS scale was excellent (M = 86.5 ± 11.5). Conclusion: This research allowed elaborating the final version of iSupport-BR, considering usability and acceptability of the platform and the program for computers/notebooks, being a pioneer in evaluating it for use in smartphones. Future research studies will have to assess the effects of iSupport-BR on the caregivers' mental health.

Duration of night sleep and cognitive performance of community older adults.

OBJECTIVE: to analyze the relationship between the duration of self-reported night sleep and the cognitive performance of older adults. METHOD: the sample consisted of 156 older adults registered in Family Health Units (FHUs) in a city of São Paulo, divided into quartiles according to the duration of night sleep. Data collection was performed using a characterization questionnaire, Addenbrooke's Cognitive Exam - Revised (ACE-R) and Pittsburgh Sleep Quality Index (PSQI). Descriptive, comparative and correlational statistical analyses were performed. RESULTS: the older adults obtained a mean of 61.94 points in ACE-R and 55.1% presented good sleep quality. Comparative analyses showed differences between the groups only in the cognitive domain of verbal fluency (p=0.018). The post-hoc analyses showed that older adults who slept more hours, a mean of 8.85 hours (Q1), had lower scores when compared to those who slept a mean of 6.11 hours (Q3) (p=0.004) and of 4.52 hours (Q4) (p=0.045). The adjusted model with application of the stepwise method showed a relationship between the independent variables of schooling and sleep duration and the domain verbal fluency. CONCLUSION: it is concluded that sleep duration is related to the verbal fluency cognitive domain.

Cognition and chronic pain: an analysis on community-dwelling elderly caregivers and non-caregivers.

BACKGROUND: In recent years there has been an increasing number of elderly people who care for another elderly person in the same household. These elderly people are more susceptible to overload and the presence of chronic pain, while pain can negatively influence cognitive variables. OBJECTIVE: To compare the performance and cognitive processing of elderly caregivers and non-caregivers with and without chronic pain. METHODS: This was a cross-sectional study carried out among 149 elderly people divided into four groups that were matched according to sex, age and schooling. The tests used were a numerical pain assessment scale, the Brief Cognitive Screening Battery (BCSB), Addenbrooke's Cognitive Examination (ACER-R) and cognitive processing through event-related potentials (P300). RESULTS: Statistically significant differences between participants with and without chronic pain were found with regard to attention/orientation (p=0.045) and visual-spatial skills (p=0.017), and in the total score (p=0.033). In the pain-free group, the caregivers showed better results than the non-caregivers. There were no effects between subjects or interactions (caregiving and pain factors) either on P300 amplitude or on P300 latency. CONCLUSION: In general, it was observed that pain-free individuals presented better performance. No relationship was observed between the factors care and pain regarding cognitive performance.

Association between perceived social support and better cognitive performance among caregivers and non-caregivers.

OBJECTIVE: to identify the association between the characteristics of the support network and cognitive performance of older caregivers and compare characteristics between caregivers and non-caregivers. METHODS: we evaluated 85 older caregivers and 84 older non-caregivers registered with primary care units regarding sociodemographic characteristics, cognition, and social support. Multiple linear regression analysis was performed. RESULTS: among non-caregivers, significant associations were found between a better cognitive performance and receiving emotional/affectionate support; each one-point increase in the emotional support score and affectionate support score was related to a 0.43-point and 0.39-point increase in cognitive assessment, respectively. Among older caregivers, each one-point increase in the emotional support score was related to a 0.55-point increase in cognitive assessment. CONCLUSION: strengthening the support networks of older caregivers and encouraging satisfactory exchanges of social support can assist in improving cognitive performance, which can have a positive impact on caregivers' health.

Association between cognitive impairment and criteria for frailty syndrome among older adults.

OBJECTIVE: The association between cognitive impairment and physical frailty has been studied in older adults. The criteria degree of frailty may be keys to associated cognitive impairment. To analyze the association between cognitive impairment and the criteria for frailty. METHODS: We cross-sectionally examined data from 667 older adults (≥60 years of age) from a study entitled 'Variables associated to cognition in elderly caregivers' involving patients in an urban and rural primary healthcare center. We defined cognitive impairment based on different groups of scores on the Mini Mental State Examination, and defined frailty and prefrailty using the criteria by the Cardiovascular Health Study. We performed multinomial regression models to analyze the association between levels of frailty and cognitive impairment. RESULTS: Similar proportions of women (54.8%) and men (45.2%) participated in the study (mean age: 71 years old). We found cognitive impairment, prefrailty and frailty in 34, 54, and 24% of the participants, respectively. Concomitant cognitive impairment and frailty was found in 13% of them. The chances of cognitive impairment increased up to 330% (Odds Ratio [OR]: 4.3; 95% confidence interval [95%CI] 2.4‒7.7; p<0.001) among frail individuals, and 70% (OR: 1.7; 95%CI 1.0‒2.8; p=0.033) among prefrail individuals compared to robust/non-frail individuals. After controlling for age, education, place of residence and functional dependence, slowness and fatigue criteria were significantly associated with cognitive impairment. CONCLUSION: Older adults with frailty have a greater likelihood of concomitant cognitive impairment than prefrail and robust older adults. The prevalence of cognitive impairment and frailty is consistent with data reported in literature. The present findings contribute to the investigation of cognitive frailty.

Cumulative effects of cognitive impairment and frailty on functional decline, falls and hospitalization: A four-year follow-up study with older adults.

OBJECTIVE: Evaluate the cumulative effects of cognitive impairment and frailty on functional decline, falls and hospitalization in older adults over a four-year period. METHOD: Four hundred five older adults (60-95 years; mean age: 70.62 ±â€¯7.12 years), 57 % female. The frailty evaluation was performed using the clinical criteria of the Cardiovascular Health Study (CHS): weight loss, fatigue, weakness, slowness and low physical activity. Cognitive impairment was defined by cutoff scores of the Mini Mental State Examination (MMSE) based on schooling. Follow-up - functional decline was assessed using the Lawton&Brody scale of instrumental activities of daily living (IADL). An investigation was also performed of the occurrence of falls and admissions to the hospital in the previous twelve months. RESULTS: Cognitive impairment was associated with admissions to the hospital and declines in the IADL category of using a telephone. Frailty was associated with admissions to hospital. Cumulative effects were observed for hospitalization and the decline in using the telephone and shopping. Frailty and cognitive impairment increased the risk of being admitted to hospital by 557 % and increased the risk of a decline in using the phone by 262% and shopping by 208%. No conditions were associated with the risk of falls. CONCLUSION: The combination of the MMSE and the CHS criteria was adequate for measuring the cumulative effects of cognitive impairment and frailty. Shared physiological mechanisms may explain the relation between cognitive impairment and frailty, but further investigations are needed in Brazil and other low/middle-income countries.
