目的：为了验证PAR协议，一种新的方法来计算人口水平的估计能量需求（EERs）和平均体力活动比率（APAR），在全国代表性样本的美国成年人。方法：估计EER和APAR值通过阶乘方程计算，从全国代表性样本的2597名成年人，年龄为20岁和74岁（美国国家健康和营养调查;数据收集于2005年1月1日至2006年12月31日）。通过与医学研究所EER方程（EERIOM）的值进行比较，验证PAR协议衍生的EER（EERPAR）值。结果：EERPAR和EERIOM之间的相关性高（0.98; P= 30）男性肥胖女性为148千卡/天（高5.7%）。2005-2006年美国人群的EER为男性2940 kcal/d，女性2275 kcal/d，范围为肥胖（BMI >= 30）男性3230 kcal/d至正常体重（BMI < 25）女性2026 kcal/d。APAR与肥胖和年龄呈显著负相关。男性和女性的APAR值分别为1.53和1.52。肥胖男性和女性的APAR值低于正常体重个体（分别为P= 0.23和P= 0.15），年轻个体的APAR值高于老年个体（P
Objective: To validate the PAR protocol, a novel method for calculating population-level estimated energy requirements (EERs) and average physical activity ratio (APAR), in a nationally representative sample of US adults.Methods: Estimates of EER and APAR values were calculated via a factorial equation from a nationally representative sample of 2597 adults aged 20 and 74 years (US National Health and Nutrition Examination Survey; data collected between January 1, 2005, and December 31, 2006). Validation of the PAR protocol-derived EER (EERPAR) values was performed via comparison with values from the Institute of Medicine EER equations (EERIOM).Results: The correlation between EERPAR and EERIOM was high (0.98; P= 30) men to 148 kcal/d (5.7% higher) in obese women. The 2005-2006 EERs for the US population were 2940 kcal/d for men and 2275 kcal/d for women and ranged from 3230 kcal/d in obese (BMI >= 30) men to 2026 kcal/d in normal weight (BMI < 25) women. There were significant inverse relationships between APAR and both obesity and age. For men and women, the APAR values were 1.53 and 1.52, respectively. Obese men and women had lower APAR values than normal weight individuals (P=.23 and P=.15, respectively), and younger individuals had higher APAR values than older individuals (P
