Prolonged sitting time (ST) has negative consequences on health. Changing this behavior is paramount in overweight/obese individuals because they are more sedentary than those with normal weight. The aim of the study was to establish the pattern of sedentary behavior and its relationship to health, socio-demographics, occupation, and education level in Catalan overweight/obese individuals.
A descriptive study was performed at 25 healthcare centers in Catalonia (Spain) with 464 overweight/moderately obese patients, aged25 to 65 years. Exclusion criteria were chronic diseases which contraindicated physical activity and language barriers. Face-to-face interviews were conducted to collect data on age, gender, educational level, social class, and marital status. Main outcome was 'sitting time' (collected by the Marshall questionnaire); chronic diseases and anthropometric measurements were registered.
464 patients, 58.4% women, mean age 51.9 years (SD 10.1), 76.1% married, 60% manual workers, and 48.7% had finished secondary education. Daily sitting time was 6.2 hours on working days (374 minutes/day, SD: 190), and about 6 hours on non-working ones (357 minutes/day, SD: 170). 50% of participants were sedentary ≥6 hours. The most frequent sedentary activities were: working/academic activities around 2 hours (128 minutes, SD: 183), followed by watching television, computer use, and commuting. Men sat longer than women (64 minutes more on working days and 54 minutes on non-working days), and individuals with office jobs (91 minutes),those with higher levels of education (42 minutes), and younger subjects (25 to 35 years) spent more time sitting.
In our study performed in overweight/moderately obese patients the mean sitting time was around 6 hours which was mainly spent doing work/academic activities and watching television. Men, office workers, individuals with higher education, and younger subjects had longer sitting time. Our results may help design interventions targeted at these sedentary patients to decrease sitting time.
久坐对健康有负面影响。改变这种行为对于超重/肥胖个体至关重要，因为他们比体重正常者久坐时间更长。本研究的目的是确定加泰罗尼亚超重/肥胖个体的久坐行为模式及其与健康、社会人口统计学、职业和教育水平的关系。
在西班牙加泰罗尼亚的25个医疗中心对464名年龄在25至65岁之间的超重/中度肥胖患者进行了一项描述性研究。排除标准为有身体活动禁忌的慢性疾病和语言障碍。通过面对面访谈收集年龄、性别、教育水平、社会阶层和婚姻状况的数据。主要结果是“久坐时间”（通过马歇尔问卷收集）；记录慢性疾病和人体测量数据。
464名患者中，58.4%为女性，平均年龄51.9岁（标准差10.1），76.1%已婚，60%为体力劳动者，48.7%完成了中等教育。工作日的每日久坐时间为6.2小时（374分钟/天，标准差：190），非工作日约为6小时（357分钟/天，标准差：170）。50%的参与者久坐时间≥6小时。最常见的久坐活动是：工作/学术活动约2小时（128分钟，标准差：183），其次是看电视、使用电脑和通勤。男性久坐时间比女性长（工作日多64分钟，非工作日多54分钟），从事办公室工作的个体（多91分钟）、教育水平较高的个体（多42分钟）以及较年轻的受试者（25至35岁）久坐时间更长。
在我们对超重/中度肥胖患者进行的研究中，平均久坐时间约为6小时，主要用于工作/学术活动和看电视。男性、办公室工作人员、受过高等教育的个体以及较年轻的受试者久坐时间更长。我们的结果可能有助于设计针对这些久坐患者的干预措施以减少久坐时间。
