背景：体力活动（PA）在预防包括肥胖和心脏代谢紊乱在内的一系列疾病中起着重要作用。需要对PA进行大量基于人口的描述性研究，包括精确的测量，以了解PA水平不足的相对负担，并为定制干预措施提供信息。结合心脏和运动感测可以研究身体活动能量消耗（PAEE）和强度分布。我们的目的是描述PAEE和中度到剧烈的体力活动（MVPA）在UK adults.Methods：芬兰研究是一项基于人群的队列研究，12,435名年龄在29-64岁的成年人在英国剑桥郡。在个体校准（跑步机）后，参与者在自由生活中连续6天佩戴组合心率和运动传感器，从中我们得出PAEE（kJ. day（-1）.kg（-1））和MVPA时间（> 3 & > 4 MET），发作时间大于1分钟和10分钟。结果：妇女累积的PAEE平均值（SD）为50（20）kJ.day（-1）.kg（-1），1分钟和10分钟的MVPA分别为83（67）和33（39）minutes.day（-1）。相比之下，男子记录为59（23）kJ.day（-1）.kg（-1），124（84）和60（58）minutes.day（-1）。年龄和BMI也是PA的重要相关因素。与年龄的关联是相反的，在两种性别，更强烈的是比MVPA的PAEE。无论是考虑PAEE还是异速生长比例的PAEE，肥胖个体积累的PA都比正常体重的个体少（男性为-10kJ.day（-1）.kg（-1）或-15 kJ. day（-1）.kg（-2/3））。较高的收入和体力劳动与较高的PA相关;体力劳动者记录的PAEE比久坐的同行多13-16kJ.kg。总体而言，86%的女性和96%的男性累积了相当于每周150分钟的每日平均MVPA（> 3 MET）。如果仅考虑发作> 10 min，则这些值分别为49和74%（> 4 MET为15和31%）。结论：PA因年龄、性别和BMI而异，体力劳动者和高收入者较高。轻度体力活动是PAEE的主要驱动力; PA的一个组成部分，目前尚未量化为英国指南的目标。
Background: Physical activity (PA) plays a role in the prevention of a range of diseases including obesity and cardiometabolic disorders. Large population-based descriptive studies of PA, incorporating precise measurement, are needed to understand the relative burden of insufficient PA levels and to inform the tailoring of interventions. Combined heart and movement sensing enables the study of physical activity energy expenditure (PAEE) and intensity distribution. We aimed to describe the sociodemographic correlates of PAEE and moderate-to-vigorous physical activity (MVPA) in UK adults.Methods: The Fenland study is a population-based cohort study of 12,435 adults aged 29-64 years-old in Cambridgeshire, UK. Following individual calibration (treadmill), participants wore a combined heart rate and movement sensor continuously for 6 days in free-living, from which we derived PAEE (kJ.day(-1).kg(-1)) and time in MVPA (> 3 & > 4 METs) in bouts greater than 1 min and 10 min. Socio-demographic information was self-reported. Stratum-specific summary statistics and multivariable analyses were performed.Results: Women accumulated a mean (sd) 50(20) kJ.day(-1).kg(-1) of PAEE, and 83(67) and 33(39) minutes.day(-1) of 1-min bouted and 10-min bouted MVPA respectively. By contrast, men recorded 59(23) kJ.day(-1).kg(-1), 124(84) and 60(58) minutes.day(-1). Age and BMI were also important correlates of PA. Association with age was inverse in both sexes, more strongly so for PAEE than MVPA. Obese individuals accumulated less PA than their normal-weight counterparts, whether considering PAEE or allometrically-scaled PAEE (-10 kJ.day(-1).kg(-1) or -15 kJ.day(-1).kg(-2/3) in men). Higher income and manual work were associated with higher PA; manual workers recorded 13-16 kJ.kg(-1).day(-1) more PAEE than sedentary counterparts. Overall, 86% of women and 96% of men accumulated a daily average of MVPA (> 3 METs) corresponding to 150 min per week. These values were 49 and 74% if only considering bouts > 10 min (15 and 31% for > 4 METs).Conclusions: PA varied by age, sex and BMI, and was higher in manual workers and those with higher incomes. Light physical activity was the main driver of PAEE; a component of PA that is currently not quantified as a target in UK guidelines.
