Childhood obesity has been attributed to a decline in total energy expenditure (TEE). We measured TEE, physical activity, and sedentary behaviour in a representative sample of young children from Glasgow, UK, at age 3 years (n=78), and we did a follow-up study at age 5 years (n=72). Mean physical activity level (TEE/resting energy expenditure) was 1.56 (SD 0.39) at age 3 years and 1.61 (0.22) at age 5 years. Median time in sedentary behaviour was 79% of monitored hours at age 3 years (IQR 74-84) and 76% (71-80) at age 5 years. Median time spent in moderate to vigorous physical activity represented only 2% of monitored hours at age 3 years (IQR 1-4) and 4% at age 5 years (2-6). Modern British children establish a sedentary lifestyle at an early age.
儿童肥胖被认为与总能量消耗（TEE）的下降有关。我们对来自英国格拉斯哥的具有代表性的幼儿样本在3岁时（n = 78）测量了其总能量消耗、身体活动及久坐行为，并在5岁时（n = 72）进行了随访研究。3岁时平均身体活动水平（总能量消耗/静息能量消耗）为1.56（标准差0.39），5岁时为1.61（0.22）。3岁时久坐行为的中位时间占监测时长的79%（四分位距74 - 84），5岁时为76%（71 - 80）。3岁时中度至剧烈身体活动的中位时间仅占监测时长的2%（四分位距1 - 4），5岁时为4%（2 - 6）。现代英国儿童在幼年时就建立了久坐的生活方式。
