We examined prospectively whether persons who perceive their objectively measured high walkable environment as low walkable decrease their walking more and gain more weight than those with matched perceptions. Walkability was measured objectively using GIS. Corresponding perceptions were collected using the Neighborhood Environment Walkability Scale from 1027 urban Australian adults. Objective and perceived measures were dichotomized and categories of match and mismatch were created. Overall, walking levels decreased and BMI increased significantly over the four year follow-up period. Those who perceived high walkability, dwelling density or land use mix as low decreased their walking for transport significantly more than those with matched perceptions. Those who perceived high walkability, land use mix or retail density as low increased their BMI significantly more than those with concordant perceptions. These prospective findings corroborate recommendations from previous cross-sectional studies. Interventions to improve negative perceptions of walkability among those living in high walkable areas may be a relevant public health intervention to increase physical activity and support weight maintenance.
我们前瞻性地研究了那些认为客观测量的高步行环境为低步行环境的人是否比那些具有匹配感知的人减少步行更多，体重增加更多。步行能力使用 GIS 进行客观测量。使用来自 1027 名澳大利亚城市成年人的邻里环境步行能力量表收集相应的认知。客观和感知的测量被分为二项式，创建匹配和不匹配的类别。总的来说，在四年的随访期间，步行水平显著下降，BMI 显著增加。与具有匹配认知的人相比，那些认为高步行能力、居住密度或土地利用混合度低的人减少了显著更多的交通步行。与具有一致认知的人相比，那些认为高步行能力、土地利用混合度或零售密度低的人 BMI 显著增加。这些前瞻性发现与以前的横断面研究的建议相符。改善高步行区居民对步行能力的负面认知的干预措施可能是一项相关的公共卫生干预措施，以增加身体活动并支持体重维持。
