项目摘要

DESCRIPTION (provided by applicant): Mothers of an infant are much less likely to exercise regularly compared with women who have older children or no children. This low level of physical activity (PA) contributes to postpartum weight retention which can predict levels of obesity up to 15 years later. Ethnic minorities have higher rates of inactivity and gain more weight following childbirth, which places them at increased risk for cancer and other chronic diseases consistent with known health disparities for these ethnic groups. Few PA interventions have been designed to increase PA in women with an infant, especially ethnic minority women. This study will test the efficacy of a tailored intervention to increase and maintain PA in a multiethnic population of 384 young, healthy postpartum women living in Hawaii. Women will be recruited from health care settlings, mother/baby support groups, and through a coalition of over 800 community organizations that provide clinical care and promote maternal and child health in women, many of whom are low-income. Subjects will be randomly assigned to either a tailored postpartum counseling intervention on PA or standard care for PA. The tailored PA intervention will address key personal, social, and environmental factors derived from Social Cognitive Theory (SCT) and the Transtheoretical Model (TTM). Also, multimodal contacts (telephone, e-mail, website) will be used to deliver theoretically-derived, culturally sensitive PA counseling,behavioral skills training (e.g., goal setting), and local resources/referrals tailored to a mother with an infant. The standard care condition receives AHA/ACSM print materials/e-mails and referral to PA internet resources. The number of contacts will be similar for both conditions.The primary PA outcome is minutes of moderate/vigorous physical activity (MVPA) per week, as measured by the International Physical Activity Questionnaire, with validation by accelerometers worn by all subjects. Exercise tolerance, measured via the 6-minute walk test, is a secondary outcome. Condition differences in the initiation of PA will be tested at 6 and 12 months post- baseline, with maintenance of MVPA evaluated 24-months post-baseline. Key psychosocial, physiological, and cultural factors will be tested as mediators or moderators of PA, for example: self-efficacy, social support, TTM processes of change, ethnicity, BMI, and cultural values. This study will serve as a model for the design and implementation of PA interventions for at-risk ethnic minority postpartum women.

描述（由申请人提供）：与有孩子或没有孩子的妇女相比，婴儿的母亲定期运动的可能性要小得多。这种低水平的体育锻炼（PA）有助于产后保留，这可以预测15年后的肥胖水平。分娩后少数民族的不活动率较高，体重增加了，这使他们患癌症的风险和其他慢性疾病的风险与这些族裔的已知健康差异一致。很少有PA干预措施可以增加婴儿，尤其是少数民族妇女的女性的PA。这项研究将测试量身定制的干预措施的功效，以增加和维持PA在夏威夷居住的384名年轻，健康的产后妇女中的多种族人口中。妇女将从医疗保健定居点，母亲/婴儿支持小组以及由800多个社区组织组成的联盟中招募，这些组织提供临床护理，并促进女性的母亲和儿童健康，其中许多人是低收入的。受试者将随机分配给对PA的量身定制的产后咨询干预，或者对PA的标准护理。量身定制的PA干预将解决由社会认知理论（SCT）和跨理论模型（TTM）得出的关键个人，社会和环境因素。此外，多模式联系人（电话，电子邮件，网站）将用于提供理论上衍生的，具有文化敏感的PA咨询，行为技能培训（例如目标设定）以及针对母亲量身定制的有婴儿的本地资源/推荐。标准护理条件接收AHA/ACSM印刷材料/电子邮件，并转介给PA Internet资源。两种情况下的接触次数将相似。根据国际体育活动问卷的衡量，主要的PA结果是每周中度/剧烈体育锻炼（MVPA）的分钟，并由所有受试者戴的加速度计验证。通过6分钟的步行测试测量的运动耐受性是次要结果。在基线后6个月和12个月内，通过MVPA进行了评估，将在基线后6个月和12个月内测试PA的起始差异。关键的社会心理，生理和文化因素将作为PA的介体或主持人进行测试，例如：自我效能感，社会支持，TTM变化过程，种族，BMI和文化价值观。这项研究将作为设计和实施PA干预措施的模型。
