BACKGROUND
High postpartum weight retention is a strong independent risk factor for lifetime obesity, cardiovascular disease, and type 2 diabetes in women. Interventions to promote postpartum weight loss have met with some success but have been limited by high attrition. Internet-based treatment has the potential to overcome this barrier and reduce postpartum weight retention, but no study has evaluated the effects of an internet-based program to prevent high postpartum weight retention in women.
METHODS/DESIGN: Fit Moms/Mamás Activas targets recruitment of 12 Women, Infants and Children (WIC) Supplemental Nutrition Program clinics with a total of 408 adult (>18 years), postpartum (<1 year) women with 14.5 kg or more weight retention or a body mass index of 25.0 kg/m(2) or higher. Clinics are matched on size and randomly assigned within county to either a 12-month standard WIC intervention or to a 12-month WIC enhanced plus internet-based weight loss intervention. The intervention includes: monthly face-to-face group sessions; access to a website with weekly lessons, a web diary, instructional videos, and computer-tailored feedback; four weekly text messages; and brief reinforcement from WIC counselors. Participants are assessed at baseline, six months, and 12 months. The primary outcome is weight loss over six and 12 months; secondary outcomes include diet and physical activity behaviors, and psychosocial measures.
DISCUSSION
Fit Moms/Mamás Activas is the first study to empirically examine the effects of an internet-based treatment program, coupled with monthly group contact at the WIC program, designed to prevent sustained postpartum weight retention in low-income women at high risk for weight gain, obesity, and related comorbidities.
TRIAL REGISTRATION
This trial was registered with Clinicaltrials.gov (identifier: NCT01408147 ) on 29 July 2011.
背景
产后体重过度滞留是女性终生肥胖、心血管疾病和2型糖尿病的一个强有力的独立风险因素。促进产后体重减轻的干预措施取得了一些成功，但因高流失率而受到限制。基于互联网的治疗有潜力克服这一障碍并减少产后体重滞留，但尚无研究评估基于互联网的项目对预防女性产后体重过度滞留的效果。
方法/设计：“健康妈妈/活跃妈妈”项目旨在招募12家妇女、婴儿和儿童（WIC）补充营养项目诊所，共有408名成年（>18岁）、产后（<1年）且体重滞留14.5千克或更多或体重指数为25.0千克/平方米或更高的妇女参与。诊所按规模匹配，并在县内随机分配接受为期12个月的标准WIC干预或为期12个月的WIC强化加基于互联网的减肥干预。干预措施包括：每月面对面小组会议；访问包含每周课程、网络日记、教学视频和计算机定制反馈的网站；每周四条短信；以及WIC顾问的简短强化指导。在基线、6个月和12个月时对参与者进行评估。主要结局是6个月和12个月内的体重减轻；次要结局包括饮食和身体活动行为以及心理社会指标。
讨论
“健康妈妈/活跃妈妈”项目是第一项实证研究基于互联网的治疗项目效果的研究，该项目结合了WIC项目的每月小组联系，旨在预防有体重增加、肥胖及相关合并症高风险的低收入女性持续产后体重滞留。
