This study examined the determinants of attaining/not attaining 10 000 steps per day among older women.
Daily step counts over 7 days were measured using accelerometry. Self-reported environmental characteristics, self-efficacy, social support and functional limitations were assessed in 128 older women. The presence of areas for activity within 1 km of each participant's residence was assessed using Geographic Information Systems. Multivariate analysis of variances were used to examine the degree to which these groups differed on measured constructs, and discriminant analysis was used to determine the profiles that discriminate among those who did not attain 10 000 steps per day and those who did.
Participants who did not attain 10 000 steps per day reported lower self-efficacy (P < 0.05), greater functional limitations (P < 0.05), had significantly fewer walking paths (P < 0.05) within 1 km of their home and reported significantly less street connectivity (P < 0.05) and safety from traffic (P < 0.05) than those who achieved 10 000 steps per day.
Lack of perceived and actual environmental supports for walking, more functional limitations and lower self-efficacy are barriers to achieving 10 000 steps per day. The absence of these individual and environmental characteristics inhibits walking behavior in older women and should be considered in campaigns to promote a physically active lifestyle.
本研究考察了影响老年女性每日达到/未达到 10000 步的因素。
使用加速度计测量 7 天内的每日步数。对 128 名老年女性进行了自我报告的环境特征、自我效能感、社会支持和功能限制的评估。使用地理信息系统评估了每位参与者住所 1 公里范围内活动区域的存在情况。方差的多元分析用于检查这些组在测量结构上的差异程度,判别分析用于确定区分未达到 10000 步/天和达到 10000 步/天的人群的特征。
未达到 10000 步/天的参与者报告自我效能感较低(P<0.05),功能限制较大(P<0.05),住所 1 公里范围内的步行路径明显较少(P<0.05),并且报告街道连通性(P<0.05)和交通安全(P<0.05)明显较低。
缺乏对步行的感知和实际环境支持、更多的功能限制和较低的自我效能感是达到 10000 步/天的障碍。缺乏这些个体和环境特征会抑制老年女性的步行行为,在促进积极的生活方式的运动中应予以考虑。
