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.
产后女性（产后 12 个月内）身体活动不足的风险增加。
评估主要通过移动电话短信服务（SMS）向产后女性提供基于理论的体力活动（PA）干预的效果和可行性。
88 名女性随机分为干预组（n = 45）和最小接触对照组（n = 43）。为期 12 周的干预包括面对面的 PA 目标设定咨询、目标设定磁铁、三到五条个性化的每周 SMS 以及一名指定的支持人员，他们每周会收到两条 SMS。SMS 内容针对社会认知理论的结构。通过自我报告，在基线、6 周和 13 周评估 PA 参与和锻炼性步行的频率（每周天数）和持续时间（每周分钟数）。
干预组参与者在 13 周内增加了 1.82 天/周（SE +/- 0.18）的 PA 频率（F ((2,85)) = 4.46，p = 0.038），并增加了 1.08 天/周（SE +/- 0.24）的锻炼性步行频率（F ((2,85)) = 5.38，p = 0.02）。PA 和锻炼性步行的持续时间（每周分钟数）也出现了积极的趋势。
干预接触导致产后女性 PA 和锻炼性步行的频率增加。
