This study examined factors associated with higher sitting time in general, chronic disease, and psychologically-distressed, adult populations (aged ≥45 years). A series of logistic regression models examined potential socio-demographic and health factors associated with higher sitting (≥6hrs/day) in adults from the 45 and Up Study (n = 227,187), including four separate subsamples for analysis comprising those who had ever had heart disease (n = 26,599), cancer (n = 36,381), diabetes (n = 19,550) or psychological distress (n = 48,334). Odds of higher sitting were significantly (p<.01) associated with a number of factors across these groups, with an effect size of ORs≥1.5 observed for the high-income ≥$70,000AUD, employed full-time and severe physical limitations demographics. Identification of key factors associated with higher sitting time in this population-based sample will assist development of broad-based, public health and targeted strategies to reduce sitting-time. In particular, those categorized as being high-income earners, full-time workers, as well as those with severe physical limitations need to be of priority, as higher sitting appears to be substantial across these groups.
本研究调查了普通人群、慢性病患者以及心理困扰的成年人群（年龄≥45岁）中与久坐时间较长相关的因素。一系列逻辑回归模型分析了来自“45岁及以上研究”（n = 227,187）的成年人中，与久坐（≥6小时/天）相关的潜在社会人口统计学和健康因素，其中包括四个独立的分析子样本，分别为曾患心脏病的人群（n = 26,599）、癌症患者（n = 36,381）、糖尿病患者（n = 19,550）以及有心理困扰的人群（n = 48,334）。在这些人群中，久坐几率与许多因素显著相关（p <.01），对于高收入（≥70,000澳元）、全职工作以及有严重身体限制的人群，观察到效应值OR≥1.5。在这个基于人群的样本中，确定与久坐时间较长相关的关键因素，将有助于制定广泛的公共卫生策略和针对性策略，以减少久坐时间。特别是那些被归类为高收入者、全职工作者以及有严重身体限制的人群需要重点关注，因为在这些人群中久坐现象似乎很普遍。
