我们研究了同卵双胞胎之间和同卵双胞胎内部的步行能力和健康行为之间的关系，考虑了家庭（社区）步行能力和每个双胞胎的测量活动空间。连续活动和位置数据（通过加速度计和GPS）在79对超过2周。步行能力使用步行评分®（WS）进行估计;家庭WS是指邻里步行能力，GPS WS是指与每个参与者收集的每个GPS点相匹配的个体WS的平均值。使用1英里欧几里德（air 1 mi）和网络（net 1 mi）缓冲区，在（WHN）和邻域（OHN）外评估GPS WS。结果包括步行和中度到剧烈的体力活动（MVPA），饮食能量密度（DED）和BMI。Home WS与WHN GPS WS相关联（对于air 1 mi，B = 0.71，SE = 0.03，p < 0.001;对于net 1 mi，B = 0.79，SE = 0.03，p < 0.001）和OHN GPS WS（空气1 mi的B = 0.18，SE = 0.04，p < 0.001;净1 mi的B = 0.22，SE = 0.04，p < 0.001）。观察到家庭和GPS WS与步行的准因果关系（双胞胎内）（ps < 0.01），但MVPA，DED或BMI没有。结果支持以前的文献，邻里步行有积极的影响，步行。
We examined relationships between walkability and health behaviors between and within identical twin pairs, considering both home (neighborhood) walkability and each twin’s measured activity space. Continuous activity and location data (via accelerometry and GPS) were obtained in 79 pairs over 2 weeks. Walkability was estimated using Walk Score® (WS); home WS refers to neighborhood walkability, and GPS WS refers to the mean of individual WSs matched to every GPS point collected by each participant. GPS WS was assessed within (WHN) and out of the neighborhood (OHN), using 1-mile Euclidean (air1mi) and network (net1mi) buffers. Outcomes included walking and moderate-to-vigorous physical activity (MVPA) bouts, dietary energy density (DED), and BMI. Home WS was associated with WHN GPS WS (b = 0.71, SE = 0.03, p < 0.001 for air1mi; b = 0.79, SE = 0.03, p < 0.001 for net1mi), and OHN GPS WS (b = 0.18, SE = 0.04, p < 0.001 for air1mi; b = 0.22, SE = 0.04, p < 0.001 for net1mi). Quasi-causal relationships (within-twin) were observed for home and GPS WS with walking (ps < 0.01), but not MVPA, DED, or BMI. Results support previous literature that neighborhood walkability has a positive influence on walking.
