更高的认知能力与更多的身体活动有关。人们对认知能力和久坐行为之间的关系知之甚少。我们的研究首次考察了历史和当代的认知能力是否能客观地预测老年人的久坐行为。参与者来自3个队列（1936年洛锡安出生队列[LBC1936] [n = 271]； 2007年苏格兰西部队列：50年代[n = 310]和30年代[n = 119]）。回归模型用于评估在生命历程中不同阶段测量的一系列认知测试之间的关联，并记录了老年人7天以上的久坐行为。在20世纪50年代最年轻的2007年队列中，先前简单反应时间（RT）与后来的久坐时间显著相关（p = 0.04）。在控制了长期疾病或就业状况后，或在初始模型中修正了多重比较后，这种关系不显著。在两组老年人中（LBC1936, 2007 - 1930），没有一项认知测量与久坐行为相关。在三个队列中，任何认知测试和从坐到站的转换次数之间都没有关联。在所有队列（n = 700）中，简单RT和选择RT测量值的meta分析估计值相同，也没有显著性。总之，我们没有发现证据表明客观测量老年人的久坐时间与生命中不同时间点的认知能力测量有关，包括从童年到老年的认知变化。
Higher cognitive ability is associated with being more physically active. Much less is known about the associations between cognitive ability and sedentary behavior. Ours is the first study to examine whether historic and contemporaneous cognitive ability predicts objectively measured sedentary behavior in older age. Participants were drawn from 3 cohorts (Lothian Birth Cohort, 1936 [LBC1936] [n = 271]; and 2 West of Scotland Twenty-07 cohorts: 1950s [n = 310] and 1930s [n = 119]). Regression models were used to assess the associations between a range of cognitive tests measured at different points in the life course, with sedentary behavior in older age recorded over 7 days. Prior simple reaction time (RT) was significantly related to later sedentary time in the youngest, Twenty-07 1950s cohort (p = .04). The relationship was nonsignificant after controlling for long-standing illness or employment status, or after correcting for multiple comparisons in the initial model. None of the cognitive measures were related to sedentary behavior in either of the 2 older cohorts (LBC1936, Twenty-07 1930s). There was no association between any of the cognitive tests and the number of sit-to-stand transitions in any of the 3 cohorts. The meta-analytic estimates for the measures of simple and choice RT that were identical in all cohorts (n = 700) were also not significant. In conclusion, we found no evidence that objectively measured sedentary time in older adults is associated with measures of cognitive ability at different time points in life, including cognitive change from childhood to older age.
