Physical activity levels were low for pregnant and postpartum participants in a diet and physical activity intervention. To explore micro level characteristics of participants'neighborhoods related to physical activity, an ancillary study was conducted. This cross-sectional study encompassed the neighborhood street segments of women participating in a diet and physical activity intervention that was conducted in the Lower Mississippi Delta. A neighborhood was defined as all street segments within one-fourth walking mile of a participant's home address. Street segments were measured using the Rural Active Living Assessment's Street Segment Assessment tool. In the field and on foot, raters measured street segments using neighborhood maps with segments identified. Mean street segment length was 0.22 miles (SD = 0.14). All segments had flat terrain with residential (98%), open spaces (74%), and public/civic (34%) as the most prevalent land uses. Almost three-fourths of segments did not have any sidewalks (69%), sidewalk buffers or defined shoulders (73%), crosswalks or pedestrian signage (69%), or posted speed limits (74%).However, 88% had stop signs and almost all (96%) had street lighting and were paved multi lane roads (95%) with low traffic volume (90%). Most residential structures present were single family detached homes (95%) and the most common public/civic and commercial structures were churches (24%) and convenience stores (9%), respectively. Almost all of the street segments were rated as walk able (99%) and aesthetically pleasing (94%). Neighborhood street segments surrounding Delta Healthy Sprouts participants'homes were walk able and aesthetically pleasing. However, safety features such as sidewalks,pedestrian signage, and posted speed limit signs were lacking. To address these inadequate pedestrian safety features, infrastructure changes are needed for small rural towns.
在一项饮食与身体活动干预研究中，孕妇和产后参与者的身体活动水平较低。为了探究与身体活动相关的参与者社区的微观层面特征，开展了一项辅助研究。这项横断面研究涵盖了参与密西西比河下游三角洲地区饮食与身体活动干预的女性的社区街道段。一个社区被定义为参与者家庭住址四分之一步行英里范围内的所有街道段。街道段使用农村积极生活评估的街道段评估工具进行测量。评估人员在实地步行，使用标有街道段的社区地图对街道段进行测量。街道段平均长度为0.22英里（标准差 = 0.14）。所有街道段地势平坦，最常见的土地用途是住宅（98%）、开放空间（74%）和公共/市政用地（34%）。近四分之三的街道段没有任何人行道（69%）、人行道缓冲区或明确的路肩（73%）、人行横道或行人标志（69%），也没有张贴限速标志（74%）。然而，88%的街道段有停车标志，几乎所有街道段（96%）都有路灯，并且是铺设的多车道道路（95%），交通流量较低（90%）。现存的大多数住宅建筑是独栋房屋（95%），最常见的公共/市政和商业建筑分别是教堂（24%）和便利店（9%）。几乎所有街道段都被评为适合步行（99%）且美观宜人（94%）。三角洲健康新芽项目参与者家周围的社区街道段适合步行且美观宜人。然而，缺少人行道、行人标志和张贴的限速标志等安全设施。为了解决这些行人安全设施不足的问题，农村小镇需要进行基础设施改造。
