Abstract

Aim: To examine if built environment is associated with changes in leisure-time physical activity, in physical activity as transportation, and with nutritional status in adults living in Sao Paulo city. Methods: Cohort study that will use baseline of Sao Paulo Health Survey that was conducted in 2014-2015. The sample was done by cluster and 3,406 adults with 18 years or older from 150 Census Tracts of the five health administrative areas (30 Census Tracts by area) were interviewed. Physical activity was evaluated by questionnaires and the nutritional status by body mass index with self-report of weight and height. The address of 3,145 adults (92.5% of total) was geocoded and buffers were constructed around the homes (500, 1,000, and 1,500 meters) with built environment variables collected by official sites of municipality government and demographic Census of 2010. From 2019 will be conducting the second survey in households for physical activity evaluation by questionnaires and by accelerometers and the new self-report of weight and height. The update of built environment variables and also will be conducted the audit evaluation around the home address. The plan is interview at least 70% of adults that had geocoded address (n=2,201). Will be conducted the cost-effectiveness analysis to examining the possibilities of public policies and programs to promote physical activity and preventive maintenance of healthy weight. Data Analysis: The outcomes will be leisure time physical activity, transportation physical activity, moderate and vigorous physical activity, sedentary behaviour, and body mass index to calculate overweight and obesity. The exposure variables will be the built environment within buffers. For statistical analysis will be used multilevel regression models using clusters of households and census tracts. (AU)
