The Health Survey of São Paulo - ISA-Physical Activity and Environment Longitudinal Study.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe main objective of the Health Survey of São Paulo or Inquérito de Saúde de São Paulo (ISA) in Portuguese, is to generate health indicators to support research and policy planning. The ISA-Physical Activity and Environment Longitudinal Study has the primary objective of examining built and social environmental determinants of leisure-time physical activity and active transportation.
participantsThe baseline (2014-2015) study included 4042 participants aged 12 years and older, men and women, living across the five regions of São Paulo city. Data were collected through household interviews. The second wave (2020-2021) used telephone interviews and included 1434 participants aged 18 or older, 58.6% female and representing 35% of the baseline sample. The third wave (2023-2024) included 1583 participants through household or telephone interviews, 58.6% of female and represented 39% of the original cohort. FINDINGS TO DATE: The study has collected extensive individual-level data, including physical activity behaviours, health status and related behaviours, self-report of diseases and sociodemographic characteristics; built environment features such as public open spaces, transport infrastructure, schools and healthcare facilities, walkability index, sidewalks, traffic control and social environment features, such as crime occurrence and socioeconomic index. Analyses have identified changes in the built environment and their associations with physical activity and obesity. Infrastructure improvements, such as the increase of bike paths and outdoor gyms, have been more frequent in wealthier areas, reinforcing spatial inequalities. Increased availability of public open spaces has been associated with increased leisure-time walking. Obesity has shown a growing trend, particularly among specific sociodemographic groups, while physical activity has demonstrated protective effects against obesity. Cycling for transportation has remained stable over time, with disparities by gender and physical activity status. FUTURE PLANS: The plan is to conduct the fourth wave in 2026 and 2027 and the fifth wave in 2029 and 2030.
