Adaptacao transcultural e confiabilidade de medidas de caracteristicas autorreferidas de vizinhanca no ELSA-Brasil

Abstract

OBJECTIVE:To describe the process involved in adapting scales for measuring neighborhood characteristics to Brazilian Portuguese. METHODS:The dimensions addressed were social cohesion, environment suitable for physical activity, availability of healthy foods, safety, perceived violence and victimization. The adaptation process involved assessment of equivalence between the original scales and the Portuguese versions. The testretest reliability was assessed in a subsample of 261 participants from the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil), who answered the same questionnaire on two different occasions, separated by an interval of 7 to 14 days. RESULTS:The aspects of equivalence assessed were shown to be adequate. The intraclass correlation coeffi cient ranged from 0.83 (95%CI 0.78;0.87) for Social Cohesion to 0.90 (95%CI 0.87;0.92) for Walking Environment. The scales showed internal consistency (Cronbach's alpha) ranging from 0.60 to 0.84. CONCLUSIONS:The measurements on self-reported neighborhood characteristics had very good reproducibility and good internal consistency (Cronbach's alpha). The results suggest that these scales can be used in studies involving Brazilian populations with characteristics similar to those of ELSA-Brasil. The conditions that trigger the greatest proportion of health outcomes occur within the sociocultural environment in which individuals live, at a collective or contextual level. Over the last few decades, there has been renewed public health interest 27 in the importance of the social and geographical context, especially in places where people live, and its impact on health. Scales for assessing neighborhood characteristics have been devised in order to pick up processes that occur in ordinary residential areas in which the population shares similar physical and social environmental conditions under which routine activities take place. 18 The effects of different neighborhoods on health have been shown, for example, in relation to the quality of life of the elderly population, 4 lifestyle habits, 15 self-reported health 22 and cardiovascular diseases. 10,11,24 Stressful factors present in the physical and social environment of the neighborhood have been shown to be positively associated with higher prevalence of diabetes, 3 obesity, 21 acute myocardial infarction, 6 smoking 13 and depression. 13 As well as diseases that can be medically diagnosed, studies have also addressed the infl uence of the neighborhood on subclinical markers of chronic diseases 17 and on variations in the levels of cortisol, 12 a hormone related to stress. DESCRIPTORS:The contextual characteristics that potentially infl uence health can be grouped into socioeconomic, physical and psychosocial dimensions. 26 Secondary databases have comprised the main source of contextual information in recent studies. However, individuals' responses (primary data) to relevant questions about processes that occur in the neighborhood and also the defi nitions of measurements inherent to the contex...

Adherence to physical activity in adults with chronic diseases: ELSA-Brasil

“…Three factors were investigated regarding the participant’s neighborhood: opportunity to practice PA, seeing persons practicing PA, and facilities to practice PA 14 . These factors were evaluated by three consecutive statements: “My neighborhood offers many opportunities to be physically active”, “I often see other people exercising in my neighborhood”, and “Local sports clubs and other facilities in my neighborhood offer many opportunities to get exercise”.…”

Cross cultural adaptation of Collett-Lester Fear of Death Scale to the brazilian reality / Adaptação transcultural da Collett-Lester Fear of Death Scale à realidade brasileira

“…[27][28][29] However, in a study carried out by the 4th author of the present study, together with Kimura, 30 the author of the original version of the scale that was being adapted to the Portuguese language requested that the back-translation be performed after obtaining the version originated from the conceptual and cultural equivalences. Associated with this, the 3rd and 4th authors of the present study have already developed a research in which back-translation was performed from the focus groups 3 and therefore it was decided in this study that back-translation was performed after GF.…”

Consumo alimentar em participantes do Projeto Saúde Brumadinho

“…A percepção do ambiente alimentar dos participantes foi investigada pelo relato da presença de estabelecimentos comerciais de alimentos (mercados, feiras livres ou outros pontos de venda) com variedade de FH frescas na vizinhança. Essa pergunta integra uma escala de vizinhança autorreferida, que foi validada em população brasileira 15 . A área de residência foi analisada com base nos três domínios amostrais: demais regiões, região diretamente atingida pelo rompimento da barragem e região de mineração.…”
