Background In prevention, sedentary behaviour and physical activity have been associated with risk of cardiovascular disease and mortality. Less is known about associations with utilization of hospital care. Aim To investigate whether physical activity level and sedentary behaviour prior to cardiac ward admission can predict utilization of hospital care and mortality among patients with cardiovascular disease. Methods Longitudinal observational study including 1148 patients admitted and treated in cardiac wards in two hospitals. Subjective reports of physical activity levels and sedentary time prior to admission were collected during inpatient care and categorized as low, medium or high. The associations between physical activity level and sedentary time with hospital stay, readmission and mortality were analysed using linear, logistic and Cox regressions. Results Median hospital stay was 2.1 days. One higher step in the physical activity level, or lower sedentary time, was related to an approximately 0.9 days shorter hospital stay. Sixty per cent of patients were readmitted to hospital. The risk of being readmitted was lower for individuals reporting high physical activity and low sedentary time (odds ratios ranging between 0.44 and 0.91). A total of 200 deaths occurred during the study. Mortality was lower among those with high and medium physical activity levels and low sedentary time (hazard ratios ranging between 0.36 and 0.90). Conclusion Both physical activity level and sedentary time during the period preceding hospitalization for cardiac events were predictors of hospital utilization and mortality. This highlights the prognostic value of assessing patients’ physical activity and sedentary behaviour.

入院前身体活动水平和久坐时间的主观报告可以预测心血管疾病患者的住院治疗利用率和全因死亡率

背景 在预防方面，久坐行为和身体活动与心血管疾病和死亡率的风险有关。关于与使用医院护理的关联知之甚少。目的 调查心脏病房入院前的身体活动水平和久坐行为是否可以预测心血管疾病患者的医院护理利用率和死亡率。方法对两家医院心脏病房收治的1148例患者进行纵向观察研究。在住院治疗期间收集入院前身体活动水平和久坐时间的主观报告，并将其分类为低、中或高。使用线性、逻辑回归和 Cox 回归。结果中位住院时间为2.1天。身体活动水平的提高或久坐时间的降低与住院时间缩短约 0.9 天有关。60% 的患者重新入院。报告高体力活动和低久坐时间的个体再次入院的风险较低（优势比介于 0.44 和 0.91 之间）。研究期间共有 200 人死亡。高和中等体力活动水平和低久坐时间的人死亡率较低（风险比在 0.36 和 0.90 之间）。结论 因心脏事件住院之前的身体活动水平和久坐时间都是医院利用率和死亡率的预测因子。
