Impact of improved urban environment and coaching on physical condition and quality of life in elderly women: a controlled study.

BACKGROUND: Physical activity can slow the ageing process and preserve autonomy in the elderly. The aim of this study was to assess the combined impact of an organized urban walking circuit and individual coaching on women senior citizens' physical well-being and quality of life. METHODS: Insufficiently physically active women >65 years were included in a quasi-experimental trial. Active arm: District with improved urban environment (IUE). Control arm: District without improved urban environment (WIUE). In each district, subjects were randomly allocated to receive coaching (C+ vs. C-). The main outcome measures were endurance, physical activity score, flexibility, quality of life, physical self-esteem, ageing exercise stereotypes, functional health and perceived health at baseline, three (M3) and six (M6) months. RESULTS: Fifty-two insufficiently physically active women were included, 23 in IUE and 29 in WIUE. Groups were comparable at baseline. At M3, endurance and physical activity score significantly improved compared with baseline in the IUE group and in the C+ group while no statistically significant change was observed for the WIUE group and the C- group. Moreover, endurance score was higher in the IUE group, whether coupled with coaching or not. After the coaching was removed, the IUE group regresses to baseline overall and the WIUE shows a decrement in endurance. CONCLUSION: Our study highlights the positive impact of an improved environment and of individual coaching on the level of physical activity and quality of life of insufficiently physically active elderly women.
