Randomized Controlled Trial of an Improved Version of MobileMums, an Intervention for Increasing Physical Activity in Women with Young Children
Women with young children (<5 years) are an important group for physical activity intervention.
The objective of the study was to evaluate the feasibility, acceptability, and efficacy of MobileMums—a physical activity intervention for women with young children.
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.
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.
MobileMums increased women’s self-reported MVPA immediately post-intervention. Future investigations need to target sustained physical activity improvements (ACTRN12611000481976).
