Influences of Mental Health on Physical Activity in Schizophrenia Patients
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.39 Vol.39】
ABSTRACT
Schizophrenia patients have increased mortality and morbidity, mainly due to premature cardiovascular disease resulting from decreased physical activity. However, how mental health factors, such as social function and quality of life (QoL), are related to decreased physical activity is unknown. To assess physical activity, social function and QoL, the International Physical Activity Questionnaire (IPAQ), Social Functioning Scale (SFS) and Schizophrenia Quality of Life Scale (SQLS), respectively, were used in 109 schizophrenia patients and 69 healthy subjects. A meta-analysis comparing physical activity intensities (vigorous, moderate and light) assessed by the IPAQ between schizophrenia patients and healthy subjects after including our sample (109 schizophrenia patients and 69 healthy subjects) was performed. Furthermore, the influences of social function and QoL on each level of physical activity intensity were investigated in patients and controls. The meta-analysis in 212 schizophrenia patients and 132 healthy subjects revealed that patients showed lower total physical activity, particularly vigorous physical activity, compared with controls (P=2.80×10⁻⁴). The decreased total physical activity was correlated with impaired total SFS scores (P=2.86×10⁻³), withdrawal (P=3.74×10⁻³) and recreation (P=3.49×10⁻³) without significant heterogeneity between patients and controls. In contrast, the decreased total physical activity was affected by low independence-performance (P=0.034), employment/occupation (P=8.74×10⁻³), psychosocial (P=0.021) and motivation/energy (P=0.013), but only in patients. Similar findings were obtained for vigorous physical activity but not moderate or light physical activity. Our findings suggest that the impaired vigorous physical activity in schizophrenia patients may be mediatedby schizophrenia-specific factors of social functioning and QoL. Understanding these factors has important implications for increasing physical activity participation in schizophrenia patients. In addition, further study is needed to clarify whether the physical activity is impaired in the first-degree relative of schizophrenia patients.
