BREAST CANCER WALKING STUDY

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。本初步研究的目的是：1）量化12周居家步行干预和12周步行与饮食联合干预对乳腺癌幸存者体力活动水平、健康、生活质量、身体成分和雌激素代谢的影响，2）开发并测试体力活动和饮食干预材料的可行性，用于该人群的未来研究。我们假设，随机分配到步行干预的妇女将报告更高水平的体力活动和身体状况的生活质量指标，保持其初始体重，并具有更有利的雌激素代谢产物。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The objectives of this pilot study are to; 1) quantify the effect of a 12 week home based walking intervention and a combined 12-week walking and diet intervention on physical activity levels, fitness, quality of life, body composition, and estrogen metabolism in survivors of breast cancer, and 2) develop and test the feasibility of physical activity and diet intervention materials for future studies in this population. We hypothesize that women randomized to the walking intervention will report higher levels of physical activity, and quality of life indicators for physical status, maintain their initial body weight, and have more favorable estrogen metabolite profiles.
