背景虽然人格特质和自我报告的身体活动之间的关联被很好地复制，很少有研究探讨了人格和基于设备的测量身体活动和久坐行为之间的关联。低水平的体力活动和高水平的久坐不动的行为是已知的危险因素较差的健康结果在老年人agile.MethodsWe使用基于设备的措施，体力活动和久坐不动的行为记录在7天以上的271 79岁的参与者洛锡安出生队列1936年。线性回归模型被用来评估人格特质是否与步数、久坐时间和从坐到站的转换次数有横断面相关性。个性特征一次输入一个，然后全部输入，在模型1中控制年龄和性别，在模型2中控制BMI和限制长期疾病。结果在控制使用错误发现率检验的多重比较后，人格特质与身体活动和久坐行为的测量之间的关联均不显著结论：我们没有发现任何证据表明人格特征与老年人基于设备的体力活动或久坐行为的测量有关。需要更多的研究来复制和检查这些关系的性质。
BackgroundWhile the associations between personality traits and self-reported physical activity are well replicated, few studies have examined the associations between personality and device-based measures of both physical activity and sedentary behaviour. Low levels of physical activity and high levels of sedentary behaviour are known risk factors for poorer health outcomes in older age.MethodsWe used device-based measures of physical activity and sedentary behaviour recorded over 7 days in 271 79-year-old participants of the Lothian Birth Cohort 1936. Linear regression models were used to assess whether personality traits were cross-sectionally associated with step count, sedentary time, and the number of sit-to-stand transitions. Personality traits were entered one at a time, and all-together, controlling for age and sex in Model 1 and additionally for BMI and limiting long-term illness in Model 2.ResultsNone of the associations between personality traits and measures of physical activity and sedentary behaviours remained significant after controlling for multiple-comparisons using the False Discovery Rate test (all ps>.07).ConclusionsWe found no evidence that personality traits are associated with device-based measures of physical activity or sedentary behaviour in older age. More studies are needed to replicate and examine the nature of these relationships.
