title: Randomized Controlled Trial of an Improved Version of MobileMums, an Intervention for Increasing Physical Activity in Women with Young Children.
abstract: BACKGROUND
  Women with young children (<5 years) are an important group for physical activity intervention.
  
  
  OBJECTIVE
  The objective of the study was to evaluate the feasibility, acceptability, and efficacy of MobileMums-a physical activity intervention for women with young children.
  
  
  METHODS
  Women were randomized to MobileMums (n = 133) or a control group (n = 130). MobileMums was delivered primarily via individually tailored text messages. Moderate to vigorous physical activity (MVPA) was measured by self-report and an accelerometer at baseline, end of the intervention (13 weeks), and 6 months later (9 months). Changes were analyzed using repeated-measures models.
  
  
  RESULTS
  MobileMums was feasible to deliver and acceptable to women. Self-reported MVPA duration (minutes/week) and frequency (days/week) increased significantly post-intervention (13-week intervention effect 48.5 min/week, 95 % credible interval (CI) [13.4, 82.9] and 1.6 days/week, 95 % CI [0.6, 2.6]). Intervention effects were not maintained 6 months later. No effects were observed in accelerometer-derived MVPA.
  
  
  CONCLUSIONS
  MobileMums increased women's self-reported MVPA immediately post-intervention. Future investigations need to target sustained physical activity improvements (ACTRN12611000481976).
