To describe the methods employed to assess the built environment and physical activity (PA) as part of a multicenter international study, and to discuss the challenges faced to obtain the necessary data in the Brazilian context.
In 2010 a household survey was conducted with adults aged from 20 to 65 years in the city of Curitiba, Brazil. The study involved the used of geo-referenced information to measure walkability in all 2 125 census sectors in Curitiba. Census sectors were categorized by walkability and income, taking into consideration the average income of heads of the family in each sector. Physical activity was assessed by self- report and using an objective measure (accelerometers).
Sixteen high walkability and 16 low walkability sectors were studied, with eight high-income and eight low-income sectors in each category. A total of 699 subjects were interviewed and 381 wore accelerometers. The response rate was 66.4% for the interviews and the compliance with accelerometer use was 85.8% (n = 327).
The results show that it is feasible to conduct high-quality studies on physical activity and built environment in the Brazilian context in accordance with international standards.
描述作为一项多中心国际研究的一部分，用于评估建成环境与身体活动（PA）的方法，并讨论在巴西背景下获取必要数据所面临的挑战。
2010年，在巴西库里蒂巴市对20至65岁的成年人进行了一项家庭调查。该研究利用地理参考信息来测量库里蒂巴市所有2125个人口普查区的步行适宜性。根据步行适宜性和收入对人口普查区进行分类，同时考虑每个区家庭户主的平均收入。通过自我报告和使用客观测量工具（加速度计）来评估身体活动。
研究了16个高步行适宜性区和16个低步行适宜性区，每个类别中有8个高收入区和8个低收入区。总共采访了699名受试者，381人佩戴了加速度计。访谈的回复率为66.4%，加速度计的使用依从率为85.8%（n = 327）。
结果表明，在巴西背景下按照国际标准开展关于身体活动和建成环境的高质量研究是可行的。
