这项研究调查了在老年人中客观测量的久坐活动和代谢综合征之间的关系。数据来自1,367名男性和女性，年龄为60岁，他们参加了2003年至2006年的全国健康和营养检查调查(NHANES)。清醒时的久坐时间是用加速计(每分钟100次)测量的。久坐比赛被定义为一段时间&>5分钟。久坐休息被定义为久坐时间的中断(≥每分钟100次)。代谢综合征的定义根据成人治疗小组(ATP)III标准。平均而言，人们久坐的时间为9.5小时(65%的穿戴时间)。与没有代谢综合征的人相比，患有代谢综合征的人久坐的时间比例更高(67.3%比62.2%)，平均久坐的时间更长(17.7分钟比16.7分钟)，久坐的强度更低(14.8比15.8每分钟)，经年龄和性别调整后，久坐的休息时间更少(82.3比86.7)(均P<；0.01)。在对年龄、性别、种族、教育、饮酒、吸烟、BMI、糖尿病、心脏病和体力活动进行调整后，久坐的时间比例越高，久坐休息的时间越少，患代谢综合征的可能性就越大。久坐时间的强度与代谢综合征之间的关联接近显着。久坐时间的比例与代谢风险密切相关，与体力活动无关。目前的结果表明，老年人可能会受益于减少总久坐时间，并通过增加久坐时间的休息次数来避免长时间的久坐。
This study examined the association between objectively measured sedentary activity and metabolic syndrome among older adults. Data were from 1,367 men and women, aged ≥60 years who participated in the 2003–2006 National Health and Nutrition Examination Survey (NHANES). Sedentary time during waking hours was measured by an accelerometer (<100 counts per minute). A sedentary bout was defined as a period of time >5 min. A sedentary break was defined as an interruption in sedentary time (≥100 counts per minute). Metabolic syndrome was defined according to the Adult Treatment Panel (ATP) III criteria. On average, people spent 9.5 h (65% of wear time) as sedentary. Compared with people without metabolic syndrome, people with metabolic syndrome spent a greater percentage of time as sedentary (67.3 vs. 62.2%), had longer average sedentary bouts (17.7 vs. 16.7 min), had lower intensity during sedentary time (14.8 vs. 15.8 average counts per minute), and had fewer sedentary breaks (82.3 vs. 86.7), adjusted for age and sex (all P < 0.01). A higher percentage of time sedentary and fewer sedentary breaks were associated with a significantly greater likelihood of metabolic syndrome after adjustment for age, sex, ethnicity, education, alcohol consumption, smoking, BMI, diabetes, heart disease, and physical activity. The association between intensity during sedentary time and metabolic syndrome was borderline significant. The proportion of sedentary time was strongly related to metabolic risk, independent of physical activity. Current results suggest older people may benefit from reducing total sedentary time and avoiding prolonged periods of sedentary time by increasing the number of breaks during sedentary time.
