Studies examining associations of socio-eco-demographic characteristics with physical activity (PA) participation of older adults have produced inconsistent results. Perceived PA barriers may be a possible explanation for the mixed findings. Therefore, the purpose of this study was to examine the correlation of socio-eco-demographic (SED) characteristics with PA of older adults and the moderation effects of perceived barriers of PA. Three hundred eighty-four older adults (≥ 60 years old) were recruited from public places in six different cities. Questions regarding socio-eco-demographic characteristics, PA, and perceived PA barriers were asked, in-person, by two examiners. Ordinal logistic regression models examined the association of socio-eco-demographic characteristics with subjectively measured PA, and the interactive effects of subscales of perceived PA barriers and socio-eco-demographic variables for PA outcomes. Significant main effects for PA outcomes were found for education and living status (P < 0.01) and college-educated individuals and those were living in their private houses reported higher PA. Also, 24 significant interactive effects of perceived PA barriers by socio-eco-demographic factors were found (P < 0.05). Significant moderation effects by all subscales of perceived PA barriers were observed for education and living status. The effect of age for the PA outcomes was moderated by “lack of time”, “fear of injury”, and “lack of skill”. Only “fear of injury” and “lack of time” moderated the effect of gender and marriage for outcome variable, respectively. The effect of employment was moderated by “lack of willpower”, “fear of injury”, “lack of skill” and “lack of resources”. Novel evidence revealed that there are moderations by perceived PA barriers for the effect of almost all socio-eco-demographic characteristics. These findings highlight a need to consider older adults’ perspectives and perceptions, when it comes to establish policies for PA participation.

社会生态人口特征和感知身体活动障碍对老年人身体活动水平的交互影响

研究社会生态人口特征与老年人身体活动 (PA) 参与之间的关联的研究产生了不一致的结果。感知到的 PA 障碍可能是对混合结果的可能解释。因此，本研究的目的是研究社会生态人口学（SED）特征与老年人 PA 的相关性以及 PA 感知障碍的调节作用。从六个不同城市的公共场所招募了 384 名老年人（≥ 60 岁）。两名考官亲自询问了有关社会生态人口特征、PA 和感知的 PA 障碍的问题。序数逻辑回归模型检查了社会生态人口特征与主观测量 PA 的关联，以及感知的 PA 障碍和社会生态人口变量对 PA 结果的交互影响。教育和生活状况对 PA 结果有显着的主效应（P < 0.01），受过大学教育的人和住在私人住宅中的人报告的 PA 更高。此外，社会-生态-人口因素对感知的 PA 障碍有 24 个显着的交互作用（P < 0.05）。观察到所有感知 PA 障碍的分量表对教育和生活状况的显着调节作用。年龄对 PA 结果的影响受到“缺乏时间”、“害怕受伤”和“缺乏技能”的影响。只有“害怕受伤”和“没有时间”分别调节了性别和婚姻对结果变量的影响。就业的影响因“缺乏意志力”而减弱，“害怕受伤”、“缺乏技能”和“缺乏资源”。新的证据表明，几乎所有社会生态人口特征的影响都被感知到的 PA 障碍所缓和。这些发现强调了在制定参与 PA 的政策时需要考虑老年人的观点和看法。
