Acceptability and feasibility of an online physical activity program for women over 50: a pilot trial.

Regular physical activity benefits health across the lifespan. Women in middle-age often juggle carer and work responsibilities, are often inactive, and may benefit from tailored support to increase physical activity. Establish the acceptability, feasibility, and impact on physical activity of a scalable program for women 50+ years. This pilot trial randomized participants to immediate program access, or to a wait-list control. Active Women over 50 Online program included: (1) study-specific website, (2) 8 emails or 24 SMS motivation-based messages, (3) one telephone health-coaching session. Outcomes, at 3 months, were acceptability (recommend study participation, intervention uptake), feasibility (recruitment, reach, completion), intervention impact (physical activity), intervention impressions. At baseline, 62 participants of mean (SD) age 59 (±7) years took 7459 (±2424) steps/day and most (92%) reported ≥2 medical conditions. At 3 months, acceptability and impact data were available for 52 (84%) and 57 (92%) participants, respectively. Study participation was recommended by 83% of participants. Participants mostly agreed to receive health coaching (81%) and messages (87%: email = 56%, SMS = 44%), opened 82% of emails and accessed the website 4.8 times on average. Respondents reported the intervention supported their physical activity. Intervention participants were more likely to increase steps from baseline by 2000+/day (OR: 6.31, 95% CI: 1.22 to 32.70, p =.028) than controls, and trended toward more light-intensity (p =.075) and moderate-vigorous intensity physical activity (p =.11). The Active Women over 50 Online program demonstrated acceptability and feasibility among the target population, and effectiveness in some domains in the short term. Results warrant further testing in a full-scale RCT. [ABSTRACT FROM AUTHOR]
