The Brazilian Longitudinal Study of Aging (ELSI-BRAZIL): Objectives and Design (original) (raw)

Cohort study of ageing from Bagé (SIGa-Bagé), Brazil: profile and methodology

BMC Public Health, 2021

The Bagé Cohort Study of Ageing is a population-based cohort study that has recently completed the first follow-up of a representative sample of older adults from Bagé, a city with more than 100,000 inhabitants located in the state of Rio Grande do Sul, Brazil. This is one of the first longitudinal studies to assess the impact of primary health care coverage on health conditions and inequalities. Our aim is to investigate the prevalence, incidence and trends of risk factors, health behaviours, social relationships, non-communicable diseases, geriatric diseases and disorders, hospitalisation, self-perceived health, and all-cause and specific-cause mortality. In addition, we aim to evaluate socioeconomic and health inequalities and the impact of primary health care on the outcomes under study. The study covers participants aged 60 or over, selected by probabilistic (representative) sampling of the urban area of the city of Bagé, which is covered by Primary Health Care Services. The ba...

Predictors of Normal and Successful Aging Among Urban-Dwelling Elderly Brazilians

The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2009

The association of successful aging with demographic, socioeconomic, and medical characteristics in healthy community-dwelling Brazilian individuals aged 60 years and older ( N = 345) was investigated. Participants were classifi ed as successful ( n = 214, 62%) or normal ( n = 131, 38%) agers. Successful agers participated in significantly more leisure activities (34%) than did normal agers (21%). Multivariate logistic regression analysis revealed that the number of living children was a risk factor, whereas confi dants and family income were protective factors for successful aging.

Healthy aging profile in octogenarians in Brazil

Revista Latino-Americana de Enfermagem, 2016

Objective: to identify the healthy aging profile in octogenarians in Brazil. Method: this population-based epidemiological study was conducted using household interviews of 335 octogenarians in a Brazilian municipality. The decision-tree model was used to assess the healthy aging profile in relation to the socioeconomic characteristics evaluated at baseline. All of the tests used a p-value < 0.05. Results: the majority of the 335 participating older adults were women (62.1%), were aged between 80 and 84 years (50.4%), were widowed (53.4%), were illiterate (59.1%), had a monthly income of less than one minimum wage (59.1%), were retired (85.7%), lived with their spouse (63.8%), did not have a caregiver (60.3%), had two or more children (82.7%), and had two or more grandchildren (78.8%). The results indicate three age groups with a healthier aging profile: older adults aged 80 to 84 years (55.6%), older adults aged 85 years and older who are married (64.9%), and older adults aged 8...

Sixteen-year predictors of successful aging from a Southern Brazilian cohort The PALA study

Dementia & Neuropsychologia

Successful aging (SA) is a current positive aging-related perspective and it is important to determine the variables associated with this concept. Most longitudinal population-based studies on predictors of SA were carried out in developed countries. Objective: This investigation evaluated which baseline characteristics predicted successful aging in 16 years of follow-up in a southern Brazilian cohort - the Porto Alegre Longitudinal Aging study. Methods: At baseline, 345 community-dwelling healthy independent individuals aged 60 or older were assessed for medical and psychiatric conditions, memory, orientation, judgment and problem solving, functioning in the community and at home, and hobbies. SA, according to Rowe and Kahn’s definition, was the outcome assessed in the last evaluation at a maximum 16-year follow-up. All baseline variables were evaluated as potential predictors for the outcome SA. Results: Of the 345 individuals evaluated at baseline, 32 (9.3%) participants were cla...

The multidimensional study of the elderly in the family health strategy in Porto Alegre, Brazil (EMI-SUS)

Pajar Pan American Journal of Aging Research, 2013

Population aging is a global phenomenon never experienced before, which will cause major repercussions for the health area. This paper's main objective is to describe the methods employed in a transversal epidemiological study with a target sample of 1080 elderly people, randomly selected from the Family Health Strategy in Porto Alegre (RS/Brazil). It integrates three key dimensions: epidemiological, clinical and basic sciences. A sub-sample with changes in cognition or mood make up a longitudinal study. The relevance of this work rests primarily on the synergy between research and care; aiming to improve health care for the elderly and making better use of the Brazilian National Health Service structure. In this way, there is a combination of robust methodological tools capable of accurately observing the epidemiological phenomena, associated with research in the areas of basic and multidisciplinary sciences. Research initiatives like this can bring forth benefits to a large proportion of the population who depend on the public health structure.

Brazilian Longitudinal Study of Adult Health (ELSA-Brasil): Objectives and Design

American Journal of Epidemiology, 2012

Although low-and middle-income countries still bear the burden of major infectious diseases, chronic noncommunicable diseases are becoming increasingly common due to rapid demographic, epidemiologic, and nutritional transitions. However, information is generally scant in these countries regarding chronic disease incidence, social determinants, and risk factors. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) aims to contribute relevant information with respect to the development and progression of clinical and subclinical chronic diseases, particularly cardiovascular diseases and diabetes. In this report, the authors delineate the study's objectives, principal methodological features, and timeline. At baseline, ELSA-Brasil enrolled 15,105 civil servants from 5 universities and 1 research institute. The baseline examination (2008-2010) included detailed interviews, clinical and anthropometric examinations, an oral glucose tolerance test, overnight urine collection, a 12-lead resting electrocardiogram, measurement of carotid intima-media thickness, echocardiography, measurement of pulse wave velocity, hepatic ultrasonography, retinal fundus photography, and an analysis of heart rate variability. Long-term biologic sample storage will allow investigation of biomarkers that may predict cardiovascular diseases and diabetes. Annual telephone surveillance, initiated in 2009, will continue for the duration of the study. A follow-up examination is scheduled for 2012-2013.

Aging demographic profile in municipalities in the state of Pará, Brazil

Revista brasileira de enfermagem, 2018

To investigate socioeconomic and demographic differences regarding population aging in municipalities of the state of Pará, Brazil. Ecological study with secondary demographic, socioeconomic and health data from the 144 municipalities of the state of Pará, Brazil. Data were treated with segmentation analysis, the Mann-Whitney U test and logistic regression models, with a significance level of p ≤ 0.05. Segmentation analysis provided a single variable to describe aging in the municipalities of Pará and originated two clusters, the high and low aging rate ones, with 104 (72.22%) and 40 (27.78%) municipalities in each, respectively. The fitted model revealed an association between aging and per capita income (p = 0.021), vulnerability to poverty (p = 0.003), rich to poor ratio (p = 0.012) and density of people (p = 0.019). There is heterogeneity in the population aging among the municipalities of Pará, mainly regarding socioeconomic conditions and number of people living in the municip...

Two-year follow-up study of elderly residents in S. Paulo, Brazil: methodology and preliminary results* Estudo de seguimento por dois anos de idosos residentes em São Paulo, Brasil: metodologia e resultados preliminares

1998

Introduction Previous cross-sectional studies have shown a high prevalence of chronic disease and disability among the elderly. Given Brazil’s rapid aging process and the obvious consequences of the growing number of old people with chronic diseases and associated disabilities for the provision of health services, a need was felt for a study that would overcome the limitations of crosssectional data and shed some light on the main factors determining whether a person will live longer and free of disabling diseases, the so-called successful aging. The methodology of the first follow-up study of elderly residents in Brazil is presented. Method The profile of the initial cohort is compared with previous cross-sectional data and an in-depth analysis of nonresponse is carried out in order to assess the validity of future longitudinal analysis. The EPIDOSO (‘Epidemiologia do Idoso’) Study conducted a two-year follow-up of 1,667 elderly people (65+), living in S. Paulo. The study consisted...
