低水平的体力活动导致老年精神分裂症患者的身体健康状况普遍较差。精神分裂症症状、神经认知和体力活动之间的联系尚不清楚。在设计和测试适当的干预措施之前，需要进行研究，以确定这一人群缺乏足够体育活动的原因。在这项横断面研究中，对30名年龄> 55岁的精神分裂症成人进行了症状（阳性和阴性综合征量表）、神经认知（MATRICS共识认知成套测验）和体力活动（Sensewear ProArmband）评估。Pearson双变量相关（双尾）和单变量线性回归模型用于检验以下假设：1）更严重的精神分裂症症状与较低水平的体力活动相关，2）更严重的神经认知缺陷与较低水平的体力活动相关。处理速度测试的得分越高，平均每日步数越多（p = .002），中度体力活动的平均每日分钟数越多（p = .009）。语言工作记忆任务的得分越高，中度体力活动的平均每日分钟数越多（p = 0.05）。更严重的抑郁症状与更多的平均每日久坐活动分钟数相关（p = 0.03）。对这一人群的身体活动干预势在必行。为了使身体活动干预取得成功，它必须包括增强认知和减少精神症状的成分。
Low levels of physical activity contribute to the generally poor physical health of older adults with schizophrenia. The associations linking schizophrenia symptoms, neurocognition, and physical activity are not known. Research is needed to identify the reasons for this population’s lack of adequate physical activity before appropriate interventions can be designed and tested. In this cross-sectional study, 30 adults aged > 55 years with schizophrenia were assessed on symptoms (Positive and Negative Syndrome Scale), neurocognition (MATRICS Consensus Cognitive Battery) and physical activity (Sensewear ProArmband). Pearson’s bivariate correlations (two-tailed) and univariate linear regression models were used to test the following hypotheses: 1) More-severe schizophrenia symptoms are associated with lower levels of physical activity, and 2) More-severe neurocognitive deficits are associated with lower levels of physical activity. Higher scores on a speed-of-processing test were associated with more average daily steps (p = .002) and more average daily minutes of moderate physical activity (p = .009). Higher scores on a verbal working-memory task were associated with more average daily minutes of moderate physical activity (p = .05). More severe depressive symptoms were associated with more average daily minutes of sedentary activity (p = .03). Physical-activity interventions for this population are imperative. In order for a physical-activity intervention to be successful, it must include components to enhance cognition and diminish psychiatric symptoms.
