Describe objective and subjective physical activity levels and time spent being sedentary in adults with schizophrenia or schizoaffective disorders (SZO/SA).
Baseline physical activity and sedentary behaviors were assessed among 46 overweight and obese community-dwelling adults (aged 18-70 years; BMI > 27 kg/m(2)) diagnosed with SZO/SA by DSM-IV-TR, with mild symptom severity (Positive and Negative Syndrome Scale score < 90) who were interested in losing weight and participated in the Weight Assessment and Intervention in Schizophrenia Treatment (WAIST) study from 2004 to 2008. Objective physical activity levels, measured using actigraphs, in WAIST were compared to a nationally representative sample of users (n = 46) and nonusers (n = 46) of mental health service (MHS) from the National Health and Nutrition Examination Survey (NHANES 2003-2004) matched by sex, BMI, and age.
On average, adults with SZO/SA wore actigraphs more than 15 h/d for 7 days averaging 151,000 counts/d. The majority of monitoring time (81%) was classified as sedentary (approximately 13 h/d). Moderate/vigorous and light physical activity accounted for only 2% (19 min/d) and 17% (157 min/d) of monitoring time/d, respectively. Primary source of activity was household activities (409 ± 438 min/wk). Fifty-three percent reported walking for transportation or leisure. Adults with SZO/SA were significantly less active (176 min/d) and more sedentary (756 min/d) than NHANES users of MHS (293 and 640 min/d, respectively) and nonusers of MHS (338 and 552 min/d, respectively) (P < .01).
Overweight and obese adults with SZO/SA were extremely sedentary; engaged in unstructured, intermittent, low-intensity physical activity; and significantly less active than NHANES users and nonusers of MHS. This sedentary lifestyle is significantly lower than those of other inactive US populations, is costly for the individual and community, and highlights the need for physical activity promotion and interventions in this high risk population.
描述精神分裂症或分裂情感性障碍（SZO/SA）成年患者的客观和主观身体活动水平以及久坐时间。
对46名超重和肥胖的社区居住成年患者（年龄18 - 70岁；BMI > 27 kg/m²）进行基线身体活动和久坐行为评估，这些患者根据《精神疾病诊断与统计手册》第四版修订版（DSM-IV-TR）被诊断为SZO/SA，症状严重程度较轻（阳性和阴性症状量表评分 < 90），且有减肥意愿，并于2004年至2008年参与了精神分裂症治疗中的体重评估与干预（WAIST）研究。使用活动记录仪测量的WAIST研究中的客观身体活动水平，与来自国家健康和营养检查调查（NHANES 2003 - 2004）的全国代表性心理健康服务（MHS）使用者样本（n = 46）和非使用者样本（n = 46）进行比较，匹配因素包括性别、BMI和年龄。
平均而言，患有SZO/SA的成年人连续7天每天佩戴活动记录仪超过15小时，平均每天记录151,000次计数。大部分监测时间（81%）被归类为久坐（约每天13小时）。中度/剧烈身体活动和轻度身体活动分别仅占每天监测时间的2%（19分钟/天）和17%（157分钟/天）。主要活动来源是家务活动（409 ± 438分钟/周）。53%的人报告有步行用于交通或休闲。与NHANES的MHS使用者（分别为293和640分钟/天）和非使用者（分别为338和552分钟/天）相比，患有SZO/SA的成年人活动明显较少（176分钟/天）且久坐时间更长（756分钟/天）（P <.01）。
超重和肥胖的SZO/SA成年患者久坐时间极长；进行无组织、间歇性、低强度的身体活动；且比NHANES的MHS使用者和非使用者活动明显更少。这种久坐的生活方式明显低于美国其他不活跃人群，对个人和社区成本高昂，并突出了在这一高风险人群中促进身体活动和进行干预的必要性。
