44?370 men and women were followed for 4.0 to 14.5 years during which 3451 participants died (7.8% mortality rate). Associations between different combinations of moderate-to-vigorous intensity physical activity (MVPA) and sedentary time were analysed at study level using Cox proportional hazards regression analysis
Results Across cohorts, the average time spent sedentary ranged from 8.5?hours/day to 10.5?hours/day and 8?min/day to 35?min/day for MVPA.

研究人員對(duì)44370名男女進(jìn)行了長(zhǎng)達(dá)4.0至14.5年的跟蹤研究,研究期間3451名參與者死亡(7.8%的死亡率)。研究人員分析了中到高強(qiáng)度體力活動(dòng)和久坐時(shí)間之間的關(guān)聯(lián)
平均久坐時(shí)間為8.5小時(shí)/天至10.5小時(shí)/天的試驗(yàn)參與者,中到高強(qiáng)度體力活動(dòng)為8分鐘/天至35分鐘/天。與參照組(最高體力活動(dòng)/最低久坐時(shí)間)相比,中到高強(qiáng)度體力活動(dòng)時(shí)間越低,久坐時(shí)間越長(zhǎng),死亡風(fēng)險(xiǎn)越高。

Conclusion Higher sedentary time is associated with higher mortality in less active individuals when measured . About 30–40?min of MVPA per day attenuate the association between sedentary time and risk of death.

結(jié)論:在運(yùn)動(dòng)較少的個(gè)體中,較高的久坐時(shí)間與較高的死亡率相關(guān)。每天大約30-40分鐘的中到高強(qiáng)度體力活動(dòng)降低了久坐時(shí)間和死亡風(fēng)險(xiǎn)之間的關(guān)聯(lián)。
