DESCRIPTION (provided by applicant): Project Summary/Abstract Regular physical activity at moderate to vigorous levels is known to reduce risk for cancer. The majority of adults, however, do not obtain sufficient levels of physical activity to derive the health benefits. The low level of physical activity among young women is of particular concern. The proposed study uses existing secondary data collected in an NIH-funded randomized controlled aerobic exercise training intervention called Women In Steady Exercise Research (WISER), part of the University of Minnesota's Transdisciplinary Research on Energetics and Cancer (TREC) center (U54CA116849). The aim of this study is to explore how patterns of physical activity among young women may be changed by selected social contextual factors. Specific aims are: 1) to determine the modes, frequency and duration of physical activity that young, healthy, but inactive women engage in before and after a physical activity intervention, and the variations; 2) to characterize young women's motivations for physical activity and to determine whether or not these motivations change following a physical activity intervention; 3) to evaluate qualitative data collected from a subsample of 60 participants on socio-cultural norms on body image in young women's social networks, and implications for physical activity; 4) to characterize how life circumstances, events and transitions affect women's physical activity; 5) to evaluate data collected from a subsample of 60 participants on destinations, distances and modes of transport to then assess socio-environmental influences on their walking and bicycling. Data draws from enrolled WISER participants [N = 160 exercise intervention and 160 controls], who at baseline were ages 18-30 and inactive (reporting two or fewer times per week of exercise in prior six months), but otherwise healthy. During the study, women in the intervention group participated in aerobic exercise 5 times weekly for 30 minutes during 4 months at 65-85% of their age-predicted heart rate maximum. The primary analytic tool will be the generalized linear mixed model to allow subject- specific models with correlation of measures within woman over time. Results of the proposed research will allow us to gain a closer and more dynamic understanding of behavioral cancer risk factors, in particular how life conditions and contextual factors combine with socio-cultural factors to affect physical activity among young women. This research aims to inform future cancer prevention health promotion research and intervention efforts to improve energy balance through an integrative focus on how, where and why young women incorporate physical activity into their lives. PUBLIC HEALTH RELEVANCE: Project Narrative This study aims to examine how levels of and motivations for physical activity among 320 young women aged 18-30 years may be affected by these factors: a physical activity intervention, socio- cultural norms on body image; life transitions; and their modes of transport. Results of the proposed research will allow us to gain a closer and more dynamic understanding of lifestyle cancer risk factors. This research aims to inform future cancer prevention health promotion research and intervention efforts to improve energy balance through an integrative focus on how, where and why young women incorporate physical activity into their lives.

描述（由申请人提供）：项目摘要/摘要在中度到剧烈水平的定期体力活动是众所周知的，以降低患癌症的风险。然而，大多数成年人没有获得足够的体力活动来获得健康益处。青年妇女的体育活动水平低尤其令人关切。这项拟议的研究使用了NIH资助的随机对照有氧运动训练干预中收集的现有二级数据，该干预称为女性稳定运动研究（WISER），是明尼苏达大学能量学和癌症跨学科研究（TREC）中心（U 54 CA 116849）的一部分。本研究的目的是探讨如何在年轻女性的身体活动模式可能会改变选定的社会背景因素。具体目标是：1）确定年轻、健康但不活动的女性在体育活动干预前后从事的体育活动的模式、频率和持续时间及其变化; 2）描述年轻女性体育活动的动机，并确定这些动机是否在体育活动干预后发生变化; 3）评估从60名参与者的子样本中收集的关于年轻女性社交网络中身体形象的社会文化规范以及对身体活动的影响的定性数据; 4）描述生活环境、事件和转变如何影响女性的身体活动; 5）评估从60名参与者的次级样本中收集的关于目的地、距离和交通方式的数据，然后评估社会环境对他们步行和骑自行车的影响。数据来自登记的WISER参与者[N = 160名运动干预者和160名对照者]，他们在基线时年龄在18-30岁之间，不活动（报告在过去六个月内每周运动两次或更少），但其他方面健康。在研究期间，干预组的女性在4个月内每周参加5次有氧运动，每次30分钟，心率为年龄预测最大心率的65-85%。主要分析工具将是广义线性混合模型，以允许受试者特定模型与女性内测量值随时间的相关性。拟议研究的结果将使我们能够更密切和更动态地了解行为癌症风险因素，特别是生活条件和环境因素如何与社会文化因素联合收割机结合，以影响年轻女性的身体活动。这项研究旨在为未来的癌症预防健康促进研究和干预工作提供信息，以通过综合关注年轻女性如何，在哪里以及为什么将身体活动纳入他们的生活来改善能量平衡。 公共卫生相关性： 项目叙述本研究旨在研究320名年龄在18-30岁的年轻女性的体育活动水平和动机如何受到这些因素的影响：体育活动干预，身体形象的社会文化规范;生活转变;以及他们的交通方式。拟议研究的结果将使我们能够更密切和更动态地了解生活方式癌症风险因素。这项研究旨在为未来的癌症预防健康促进研究和干预工作提供信息，以通过综合关注年轻女性如何，在哪里以及为什么将身体活动纳入他们的生活来改善能量平衡。
