Feasibility & Acceptability of a co-created pragmatic walkability program to promote mobility in older adults with fear of falling: A question of season and mobility profile?

Background: Fear of falling may limit mobility in older adults, particularly during winter. Pragmatic, community-based interventions are needed to support safe, sustainable walking. Objective: To assess the feasibility and acceptability of a co-created intervention (MABIDA) promoting utilitarian and recreational walking among older adults. Method: Fifty-two older adults with fear of falling participated in a 12-week group intervention (summer/winter) consisting of one 60-minute supervised walking session/week, incorporating exercises. Walking group level was assessed using a subjective decisional tree. Results: Forty-one participants (73.3{+/-}5.7years) completed the study (dropout: winter only). Retention and adherence exceeded 75%. Intervention settings were considered appropriate ([≥]81%). The decisional tree correctly classified 72% of participants. Participants reported satisfaction (82%) and enjoyment (81%). No differences were observed between seasons or walking groups (p>0.05). Group walking was the main facilitator (59%), while weather was the main barrier (17%). Conclusion: MABIDA appears feasible, acceptable, and adapted across seasons and walking speed profiles.
