DESCRIPTION (provided by applicant): Pregnancy is a specific event that often results in decreased physical activity for women; thereby placing this special population at increased risk for several chronic diseases and premature mortality. The existing research examining exercise during pregnancy is limited, however, with respect to the following 3 important factors: (a) cross-sectional assessments that do not capture the specific physical and psychological demands of each trimester; (b) nonstandardized and unvalidated measures of exercise with pregnant women; and (c) nontheoretical studies of exercise determinants. Before effective physical activity interventions are implemented with pregnant women, it is necessary to prospectively examine, during each trimester, women's exercise beliefs and behaviors using standardized measures of exercise behavior within a theoretical framework. This approach will provide the theoretical basis to implement exercise interventions specific to the physical and psychological demands of each trimester. The theory of planned behavior is one of the most influential and successful theories for understanding and predicting exercise intention and behavior, and will thus serve as the theoretical framework to prospectively determine the exercise beliefs and behaviors for this special population. The specific aims of this application are: (1) Determine the normative, control, and behavioral beliefs of exercise during each trimester. (2) Determine whether: (a) the beliefs predict attitude, perceived behavioral control, and subjective norm during each trimester; (b) intention and perceived behavioral control predict exercise behavior during each trimester; and (c) attitude, perceived behavioral control, and subjective norm predict exercise intention during each trimester. (3) Examine physical activity levels during each trimester. And (4) explore potential mediators and moderators of the theory of behavior.

描述（由申请人提供）：怀孕是一个特殊的事件，往往会导致减少体力活动的妇女，从而使这一特殊人群在几种慢性疾病和过早死亡的风险增加。然而，现有的研究在以下3个重要因素方面对怀孕期间的运动进行了限制：（a）没有捕捉到每个三个月的特定生理和心理需求的横截面评估;（B）非标准化和未经验证的孕妇运动测量;（c）运动决定因素的非理论研究。在对孕妇实施有效的身体活动干预之前，有必要在每个三个月期间，在理论框架内使用运动行为的标准化措施前瞻性地检查女性的运动信念和行为。这种方法将提供理论基础，以实施运动干预的具体身体和心理需求的每三个月。计划行为理论是理解和预测运动意图和行为的最有影响力和最成功的理论之一，因此将作为前瞻性地确定这一特殊人群的运动信念和行为的理论框架。本研究的具体目的是：（1）确定每个三个月期间锻炼的规范性、控制性和行为性信念。(2)确定是否：（a）信念预测每个三个月的态度、知觉行为控制和主观规范;（B）意图和知觉行为控制预测每个三个月的锻炼行为;（c）态度、知觉行为控制和主观规范预测每个三个月的锻炼意图。(3)检查每三个月的身体活动水平。（4）探索行为理论的潜在中介者和调节者。
