目的：描述成年精神分裂症或分裂情感障碍(SZO/SA)患者的主客观体力活动水平和久坐时间。方法：采用DSM-IV-TR对46名18~70岁、体重指数(BMI)、体重指数(BMI)、体重目的：将活动记录仪测量的腰部体力活动水平与国家健康与营养调查(NHANES 2003-2004)中具有全国代表性的精神卫生服务使用者(n=46)和非使用者(n=46)的性别、体重指数和年龄进行匹配。结果：平均而言，SZO/SA患者在7天内每天使用活动记录仪超过15小时，平均每天151,000次。大多数监测时间(81%)被归类为久坐(约13小时/d)。中度/剧烈和轻度体力活动分别只占监测时间的2%(19min/d)和17%(157min/d)。活动的主要来源是家庭活动(409+/-438分钟/周)。53%的人表示步行是为了交通或休闲。患有SZO/SA的成年人的活动量(176分钟/d)和久坐时间(756分钟/d)显著低于服用MHS的NHANES患者(分别为293和640分钟/d)和不服用MHS的成年人(分别为338和552min/d)(P<；0.01)。结论：患有SZO/SA的超重和肥胖成年人非常久坐不动，从事无结构、间歇性、低强度的体力活动，活动明显少于NHANES患者和不使用MHS的患者。这种久坐不动的生活方式明显低于其他不活跃的美国人群，对个人和社区来说代价高昂，并突显了在这一高危人群中促进体育活动和干预的必要性。
Objective: Describe objective and subjective physical activity levels and time spent being sedentary in adults with schizophrenia or schizoaffective disorders (SZO/SA).Method: 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.Results: 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).Conclusions: 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.
