DESCRIPTION (provided by applicant): The main objective of the proposed study is to develop an antenatal physical activity intervention to promote engagement in regular leisure physical activity (RLPA). In order to inform the development of the intervention, ethnographic studies will be conducted to better understand what factors facilitate and prevent pregnant women from engaging in RLPA and to what extent these may differ among pregnant women who are first time or veteran mothers and among pregnant women who currently engage in RLPA versus those who do not (i.e. are sedentary or engage in low levels of RLPA). The proposed pilot physical activity intervention will be designed to improve certain personal determinants (i.e. self-efficacy, behavioral skills, and social support). These personal determinants have been suggested to be effective mediators of physical activity. The specific aims of the study are to: 1) conduct ethnographic studies to examine barriers and facilitators to physical activity engagement among pregnant women; 2) Develop a manual of procedures to conduct a randomized physical activity pilot intervention to increase antenatal regular leisure physical activity; 3) Determine which recruitment strategies based on type (e.g. healthcare provider, community organizations, print advertisements) and setting (e.g. healthcare clinics, hospitals, community organizations) that produce the most effective yield; 4) Pilot test methodologies in pregnant women (n=40; 20 intervention, 20 control) to provide necessary information (e.g. effect sizes, adherence and attrition rates) to guide future implementation of a large-scale, randomized controlled physical activity intervention trial in the antenatal period. The hypotheses to be tested in the larger RCT trial include 1) women who engage in the physical activity intervention will report greater levels of physical self-efficacy, behavioral skills, and social support, compared to women in the control group; 2) women in the intervention group will report an increase in RLPA, decrease in antenatal weight gain, antenatal depression and perceived stress compared to their control counterparts; and 3) engagement in antenatal RLPA will reduce the risk of adverse birth outcomes, postpartum depression and overweight.

描述（由申请人提供）：拟议研究的主要目的是开发产前体育锻炼干预措施，以促进参与常规休闲体育锻炼（RLPA）。为了告知干预措施的发展，将进行民族志研究，以更好地了解哪些因素有助于促进和防止孕妇参与RLPA，并且在第一次或退伍军人母亲以及目前从事RLPA的孕妇中，这些因素可能有所不同，而目前从事RLPA的孕妇与那些不忍受的孕妇（即久坐或参与RLPA水平较低）。拟议的飞行员体育活动干预旨在改善某些个人决定因素（即自我效能，行为技能和社会支持）。这些个人决定因素已被认为是体育锻炼的有效介体。该研究的具体目的是：1）进行民族志研究，以检查孕妇的体育锻炼障碍和促进者； 2）制定手册，以进行随机的体育活动试验干预，以增加产前常规休闲体育锻炼； 3）确定基于类型（例如医疗保健提供者，社区组织，印刷广告）和设置（例如医疗保健诊所，医院，社区组织）的招聘策略； 4）孕妇的试验测试方法（n = 40; 20介入，20控制）提供必要的信息（例如效应大小，依从性和损耗率），以指导在产前期间进行大规模，随机对照的体育活动干预试验的未来实施。与对照组的女性相比，在较大的RCT试验中要测试的假设包括1）从事体育活动干预的妇女将报告更高水平的身体自我效能感，行为技能和社会支持； 2）干预组中的女性将报告RLPA增加，产前体重增加，产前抑郁症和与对照组相比的压力增加； 3）参与产前RLPA将降低出生不良后果，产后抑郁和超重的风险。
