产后妇女（产后< 12个月）缺乏体力活动的风险增加，为评价产后妇女通过移动的手机短信（SMS）进行基于理论的体力活动（PA）干预的有效性和可行性，将88名妇女随机分为干预组（n = 45）和最小接触控制组（n = 43）。为期12周的干预措施包括面对面的PA目标设定咨询，目标设定磁铁，每周三到五条个人定制的短信和每周收到两条短信的指定支持人员。短信内容有针对性地构建了社会认知理论。频率（日/周）和期限在基线、第6周和第13周，通过自我报告评估PA参与和步行锻炼的频率（分钟/周）。（SE +/- 0.18）第13周（F（（2，85））= 4.46，p = 0.038），13周时步行锻炼频率为1.08天/周（SE +/- 0.24）（F（（2，85））= 5.38，p = 0.02）。观察到PA持续时间（分钟/周）和步行锻炼的积极趋势。干预暴露导致产后妇女PA和步行锻炼的频率增加。
Postnatal women (< 12 months postpartum) are at increased risk of physical inactivity.To evaluate the efficacy and feasibility of a theory-based physical activity (PA) intervention delivered to postnatal women primarily via mobile telephone short message service (SMS).Eighty-eight women were randomized to the intervention (n = 45) or minimal contact control (n = 43) condition. The 12-week intervention consisted of a face-to-face PA goal-setting consultation, a goal-setting magnet, three to five personally tailored SMS/week and a nominated support person who received two SMS per week. SMS content targeted constructs of social cognitive theory. Frequency (days/week) and duration (min/week) of PA participation and walking for exercise were assessed via self-report at baseline, 6 and 13 weeks.Intervention participants increased PA frequency by 1.82 days/week (SE +/- 0.18) by 13 weeks (F ((2,85)) = 4.46, p = 0.038) and walking for exercise frequency by 1.08 days/week (SE +/- 0.24) by 13 weeks (F ((2,85)) = 5.38, p = 0.02). Positive trends were observed for duration (min/week) of PA and walking for exercise.Intervention exposure resulted in increased frequency of PA and walking for exercise in postnatal women.
