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）：与有较大孩子或没有孩子的母亲相比，有婴儿的母亲经常锻炼的可能性要小得多。这种低水平的身体活动（PA）有助于产后体重保持，这可以预测15年后的肥胖水平。少数民族在分娩后缺乏运动的比例更高，体重增加更多，这使他们患癌症和其他慢性疾病的风险更高，这与这些民族的已知健康差异一致。很少有干预措施旨在增加有婴儿的妇女，特别是少数民族妇女的PA。本研究将对居住在夏威夷的384名年轻、健康的产后妇女进行量身定制的干预，以提高和维持PA的有效性。将从保健点、母婴支助团体和800多个社区组织组成的联盟招募妇女，这些组织提供临床护理和促进妇女的妇幼保健，其中许多妇女是低收入的。受试者将被随机分配到针对PA的量身定制的产后咨询干预或PA的标准护理。量身定制的PA干预将解决源自社会认知理论（SCT）和跨理论模型（TTM）的关键个人、社会和环境因素。此外，多模式联系（电话，电子邮件，网站）将用于提供理论推导，文化敏感的PA咨询，行为技能培训（例如，目标设定），以及为有婴儿的母亲量身定制的当地资源/转介。标准护理条件接收AHA/ACSM打印材料/电子邮件，并转介到PA互联网资源。在这两种情况下，触点的数量是相似的。主要的PA指标是每周中度/剧烈身体活动（MVPA）的分钟数，由国际身体活动问卷测量，并通过所有受试者佩戴的加速度计进行验证。通过6分钟步行测试测量的运动耐受性是次要的结果。将在基线后6个月和12个月测试PA启动的条件差异，并在基线后24个月评估MVPA的维持情况。关键的社会心理、生理和文化因素将作为PA的中介或调节因素进行测试，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。本研究将为少数民族产后妇女PA干预的设计和实施提供一个模型。
