Regional differences regarding the occurrence of falls and associated factors in two populations of Brazilian longevous people.

BACKGROUND: Few studies have explored regional asymmetries and their implications for health policies regarding episodes of falls among the population of ≥80 years old in continental and developing countries like Brazil with deep inequalities and sociocultural differences. OBJECTIVE: To evaluate the occurrence of falls and their association with functional capacity and nutritional status in the longest oldest-old living in two municipalities in the Northeast and Southeast of Brazil. METHODS: This is a cross-sectional study, with primary data collection in which were included in the research seniors aged 80 years or more, of both sexes, belonging to two Brazilian municipalities of discrepant socioeconomic aspects. The dependent variable was the occurrence of falls in the last year. The independent variables were grouped into demographic aspects, functional capacity and nutritional status. To identify variables that contribute to the occurrence of falls, the multiple logistic regression model, adopts a significance level of 5%. RESULTS: The sample was composed of 415 oldest-old adults. From the total, 32.3% reported having fallen in the last year, 24.7% in Brejo dos Santos and 37.8% in São Paulo. Among the former population, the mean value of walking speed for those who had falls was 0.27 m/s and for those who had no occurrence of falls was 0.33 m/s; and, among the seniors from São Paulo, the mean values were 0.51 m/s and 0.58 m/s, respectively. Significant correlations between walking speed and falls were verified for both populations, showing that the lower the walking speed, the higher the predisposition to falls. In the final regression model, the occurrence of falls was associated with moderate balance (OR = 5.28; CI: 1.11-25.18) among the longevous people Brejo dos Santos and with very poor functional performance (OR = 16.09; CI:1.46-177.06) among those from São Paulo. CONCLUSION: The results pointed out a lower prevalence of falls in longevous people from Brejo dos Santos than in those from São Paulo and differences regarding the associated factors, showing heterogeneity between the two populations; indicating the need for public policies and effective programmes aimed at preventing falls based on the maintenance or increase of functional capacity.

Health-Related Quality of Life and Associated Factors: Regional Differences Among Oldest-Old in Brazil.

PURPOSE: The aim of this research was to investigate the extent to which socioeconomic and regional differences in Brazil may influence the quality of life. To this end, we examined factors associated with health-related quality of life in two populations of oldest-old people, aged 80 and over: one from the Northeast of Brazil and the other from the Southeast. METHODS: 417 participants aged 80 and over were interviewed face-to-face, 179 from Brejo dos Santos, one of the poorest regions in the Northeast; and 238 from São Paulo, one of the largest urban metropolises in Southeast Brazil. Data, which included socioeconomic and demographic factors, health status, and health-related quality of life, were collected using a structured questionnaire. The dependent variable was determined by the completion rate of the 12-item Short Form Survey and analyzed using multiple logistic regression. RESULTS: Although the population of São Paulo had four times as many long-lived women than men, had better literacy levels, used more medications, and presented a greater prevalence of symptoms suggestive of depression in comparison to the Northeast's population, no difference was observed in the proportion of good physical components among the two populations, 54.3% in Brejo dos Santos' oldest-old and 50.4% in São Paulo's (P = .6272). Quality and quantity of sleep were factors that most affected the health-related quality of life among the oldest-old of Northeast. CONCLUSION: Factors associated with health-related quality of life were different among the oldest-old people of the two locations, thereby corroborating the heterogeneous nature of the longevous population.

Psychosocial aspects and support networks associated with disability in two longevous populations in Brazil: a cross-sectional study.

BACKGROUND: Among the oldest old, aged 80 years and over, the prevalence of disability is higher than in other age groups and can be considered a predictor of mortality. OBJECTIVE: To evaluate how psychosocial aspects and support networks influence the disability of these oldest-old individuals, performing a comparison between two longevous populations, one living in one of the poorest regions of Brazil, in the backlands of Paraíba, and another living in one of the largest urban centres in Latin America. METHOD: A cross-sectional study in which 417 oldest-old persons aged 80 years and older were interviewed, with data collected through the "Health, Welfare and Ageing" survey conducted in two Brazilian cities. Disability was assessed by reporting the need for assistance in Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). Bivariate and multiple analyses were performed using R statistical software. RESULTS: Food insufficiency in the first years of life had negative repercussions on the disability of oldest old people living in the northeast. On the other hand, in this region, older people have a higher rate of support and live longer with their peers, which may contribute to reducing feelings of loneliness, depressive symptoms, and worse self-perception of health. In the Southeast, financial constraints, subjective poverty, and unmet needs may favour the development of functional limitations between long-lived people. CONCLUSION: Our findings indicate that regional differences in Brazil may influence the disability of older people aged 80 and older. In northeast Brazil, having no partner may contribute to disability for ADLs and IADLs; while, in the longevous population of São Paulo, having a worse self-rated health may contribute to disability for IADLs.

Socioeconomic Factors and Health Status Disparities Associated with Difficulty in ADLs and IADLs among Long-Lived Populations in Brazil: A Cross-Sectional Study.

OBJECTIVE: To evaluate the association between socioeconomic factors, health status, and Functional Capacity (FC) in the oldest senior citizens in a metropolis and a poor rural region of Brazil. METHOD: Cross-sectional study of 417 seniors aged ≥80 years, data collected through Brazil's Health, Well-being and Aging survey. FC assessed by self-reporting of difficulties in Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). Chi-square tests and multiple logistic regression analyses were performed using "R" statistical software. RESULTS: Socioeconomic and demographic inequalities in Brazil can influence FC in seniors aged 80 years and older. Comparatively, urban long-lived people had a higher prevalence of difficulties for ADLs and rural ones showed more difficulties for IADLs. Among urban oldest seniors, female gender and lower-income were correlated with difficulties for IADLs. Among rural oldest seniors, female gender, stroke, joint disease, and inadequate weight independently were correlated with difficulties for ADLs, while the number of chronic diseases was associated with difficulties for IADLs. CONCLUSION: Financial constraints may favor the development of functional limitations among older seniors in large urban centers. In poor rural areas, inadequate nutritional status and chronic diseases may increase their susceptibility to functional decline.

The prevention of arboviral diseases using mobile devices: a preliminary study of the attitudes and behaviour change produced by educational interventions.

OBJECTIVES: In Brazil, the National Policy for Dengue Control seeks to incorporate the lessons of national and international experience in dengue control, emphasising the need for health education activities. The objective of this study was to evaluate and compare knowledge, attitudes and behaviours related to the prevention of arboviruses before and after a two-month educational intervention using a learning platform on mobile devices. METHODS: This quasi-experimental study corresponds to the first phase of the project 'Impact of mobile learning in the prevention and management of complications caused by arboviruses (Zika, Dengue, Chikungunya) - ZIKAMOB', sponsored as part of the British Council Newton Fund. RESULTS: Thirty of the 93 participants were first-year undergraduate university students (36.7% male), and 63 were police officers (84.1% male). The pattern of attitudes and behaviour was very similar in both groups before the intervention. The students changed their attitudes and behaviour (P = 0.032) in relation to their engagements in actions for the prevention of arboviral diseases and several other activities related to house inspections and precautions with water tanks (P < 0.01). However, recycling and surveillance activities were not as effective in changing behaviour. Female participants showed more motivation to participate in preventive activities, but living alone and working were barriers to participation. Individuals who already perform selective waste collection and are cultivating gardens demonstrated both a positive attitude and a positive behaviour towards actions for the prevention of arboviral diseases. CONCLUSION: Mobile learning and behaviour change theories might be successful as the basis for school-based and community-based interventions to avoid arboviruses. These outcomes need to be confirmed in broader future studies.

OBJECTIFS: Au Brésil, la politique nationale de lutte contre la dengue cherche à intégrer les leçons tirées des expériences nationales et internationales en matière de lutte contre la dengue, en insistant sur la nécessité d'activités d'éducation sur la santé. L'objectif de cette étude était d'évaluer et de comparer les connaissances, les attitudes et les comportements liés à la prévention des arbovirus avant et après une intervention éducative de deux mois à l'aide d'une plate-forme d'éducation basée sur des appareils mobiles. MÉTHODES: Cette étude quasi expérimentale correspond à la première phase du projet "Impact de l'éducation mobile dans la prévention et la prise en charge des complications causées par les arbovirus (Zika, Dengue, Chikungunya) - ZIKAMOB", parrainé dans le cadre du British Council Newton Fund. RÉSULTATS: Trente des 93 participants étaient des étudiants de première année d'université (36,7% d'hommes) et 63 étaient des agents de police (84,1% d'hommes). Le modèle des attitudes et de comportement était très similaire dans les deux groupes avant l'intervention. Les étudiants ont changé leurs attitudes et comportements (P = 0,032) en ce qui concerne leur participation à des actions de prévention des maladies à arbovirus et à plusieurs autres activités liées aux inspections des maisons et aux précautions d'utilisation des réservoirs d'eau (P < 0,01). Cependant, les activités de recyclage et de surveillance n'étaient pas aussi efficaces pour le changement de comportement. Les participantes étaient plus motivées à participer aux activités de prévention, mais le fait de vivre seul et de travailler constituait un obstacle à la participation. Les personnes qui effectuent déjà une collecte sélective des déchets et cultivent des jardins ont démontré à la fois une attitude positive et un comportement positif à l'égard des actions de prévention des maladies à arbovirus. CONCLUSION: Les théories sur l'éducation mobile et le changement de comportement pourraient être couronnées de succès en tant que base d'interventions en milieu scolaire et communautaire visant à éviter les arbovirus. Ces résultats doivent être confirmés dans des études supplémentaires plus larges.
