Fjeldsoe, Brianna S., Miller, Yvette D., & Marshall, Alison L. (2010) MobileMums: A randomized controlled trial of an SMS-based physical activity intervention. Annals of Behavioral Medicine, 39(2), pp. 101-111.
Background Postnatal women (<12 months postpartum) are at increased risk of physical inactivity.
Purpose 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).
Methods 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.
Results 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.
Conclusions Intervention exposure resulted in increased
frequency of PA and walking for exercise in postnatal
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
