Physical activity of adolescents and the urban environment of Brazilian capitals: National School Health Survey, 2015.

This study aimed to evaluate the practice of physical activity (PA) among adolescents and its association with characteristics of the urban environment of Brazilian capitals. Study with adolescents from the 26 Brazilian capitals and the Federal District participating in the National School Health Survey, 2015 edition. The association between regular practice of PA (≥300 minutes/week) and the dimensions of urban well-being (urban mobility, urban environmental conditions, urban housing conditions, urban collective services, and urban infrastructure) was examined using multilevel logistic regression. A total of 50,904 adolescents were evaluated, among which 20.7% were active. It was observed in the multiple model that adolescents who live in capitals with better urban environmental conditions, such as the presence of tree coverage, less open sewage, and less accumulated garbage around the houses, are more likely to be active (OR = 1.06; 95% CI:1.01;1.12). Adolescents who live in cities with less urban disorder are more likely to be active.

Perceived neighborhood and fall history among community-dwelling older adults living in a large Brazilian urban area: a multilevel approach.

Few studies have examined the neighborhood features related to falls in the older population in low-and-middle-income countries, including Brazil. This study aimed to evaluate if perceived neighborhood features are related to falls among older Brazilian adults living in a large urban area. This cross-sectional study was conducted using data from 834 participants (≥60 years) from a multistage household survey in Belo Horizonte, Brazil. The association between fall history in the previous year and perceived neighborhood features (quality of services, physical and social disorder, and safety) was examined using multilevel logistic regression. The fall prevalence was 13.6%. Older adults living in neighborhoods with a higher physical disorder were more likely to report fall in the previous year, even after controlling for demographic, clinical and social variables (OR = 2.59; 95% CI = 1.14-5.87). The other neighborhood features investigated were not associated with a fall history. Our findings suggest that improving the physical environment represents an important strategy to prevent falls in the Brazilian urban older population.

Individual characteristics, perceived neighborhood, and walking for transportation among older Brazilian people residing in a large urban area.

This study aimed to investigate the association of individual and environmental characteristics with walking for transportation among older Brazilian people living in a large urban area. Data from 825 participants (≥ 60 years) from a multistage household survey in Belo Horizonte, Brazil, were used. Walking for transportation was evaluated using the International Physical Activity Questionnaire. The environmental variables included six perceived neighborhood scales (walkability, quality of services, physical disorder, safety, social disorder, and social cohesion). A Poisson regression analysis with robust variance was performed. The walking for transportation was significantly associated with walkability scale, lower family income (up to four minimum wages), very good/good self-rated health, and high social participation. Our results suggest that promoting adequate conditions for walkability in urban areas, expanding the opportunities for social participation, and improving general health is essential to increase walking levels for transportation among this older Brazilian population.

Examining the factors associated with functional capacity of community-dwelling older adults using the ICF framework: a cross-sectional study from the Frailty in Brazilian Older Adults Study (FIBRA).

BACKGROUND: There are many factors associated with functioning and disability in older adults and these relationships are not clear. OBJECTIVE: To explore the factors associated with functional capacity of older adults using the framework of the International Classification of Functioning, Disability, and Health (ICF). METHODS: This is a cross-sectional study with a dataset from a survey of 1 377 community-dwelling older adults (≥ 65 years) in a middle-income country. Three functional outcomes were selected to represent the functioning domains: 1) muscle strength for body function; 2) walking speed for activity; and 3) advanced activities of daily living (ADL) for participation. Demographic, clinical, and social information was selected to represent the domains of health conditions and contextual factors (i.e. personal and environmental factors). Multivariate models tested the impact of these factors on each outcome. RESULTS: Depressive symptoms, age, and physical activity were associated with the three outcomes. Muscle strength was also associated with urinary incontinence, visual deficits, female sex, and employment. Walking speed was also associated with urinary incontinence, obesity, fractures due to falls, female sex, health professionals' visits, and walking aid devices. Advanced ADL were also associated with stroke, visual deficits, education, employment, health perception, social support, and walking aid devices. CONCLUSION: Functional capacity of older adults is associated with some non-modifiable factors, such as age and sex. The modifiable factors must be addressed by health professionals and policymakers in the geriatric area, especially depression, obesity, physical inactivity, and social support.
