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妇女相比，婴儿的母亲不太可能经常锻炼。这种低水平的体力活动（PA）有助于产后体重保持，这可以预测长达15年的肥胖水平。少数民族不活动的比例较高，分娩后体重增加较多，这使他们患癌症和其他慢性病的风险增加，这与这些族裔群体已知的健康差距一致。几乎没有设计PA干预措施来增加有婴儿的妇女，特别是少数民族妇女的PA。这项研究将测试一个量身定制的干预措施，以增加和维持PA在一个多种族的人口384年轻，健康的产后妇女生活在夏威夷的有效性。将从保健安置点、母婴支助团体以及通过800多个社区组织的联盟招募妇女，这些组织提供临床护理并促进妇女的母婴健康，其中许多妇女是低收入者。受试者将被随机分配到PA的定制产后咨询干预或PA的标准护理。量身定制的PA干预将解决来自社会认知理论（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/电子邮件和转诊到PA互联网资源。主要PA结果是每周中等/剧烈体力活动（MVPA）的分钟数，由国际体力活动问卷测量，并通过所有受试者佩戴的加速度计进行验证。通过6分钟步行试验测量的运动耐量是次要结果。将在基线后6个月和12个月检测PA启动时的状况差异，并在基线后24个月评价MVPA的维持情况。将测试关键的心理社会、生理和文化因素作为PA的中介或调节因素，例如：自我效能、社会支持、TTM变化过程、种族、BMI和文化价值观。这项研究将作为一个模型的设计和实施的PA干预措施的风险少数民族产后妇女。
