目的：本研究的目的是检查正常体重、超重和肥胖男性和女性的每日总能量消耗（TDEE）、不同强度的能量消耗、每日总能量摄入（TDEI）和饮食质量的差异。进一步，研究了能量消耗和能量摄入与体脂的关系。方法：横断面分析430例成人（27.7±3.8岁，男性49.3%）。根据标准程序测量体重和身高，通过双x线吸收仪评估体脂率。能量消耗通过SenseWear臂章测定。能量摄入和健康饮食指数（HEI）是基于多次24小时回忆计算的。结果：超重和肥胖成人体重调整后的TDEI和TDEE明显低于正常体重的同龄人（p < 0.001），肥胖女性的HEI较低（p = 0.006）。超重和肥胖的成年人在久坐和轻度活动中消耗的能量比例更高（p < 0.001），而在中等到剧烈身体活动（MVPA）中消耗的能量比例低于正常体重的同龄人（p < 0.001）。BMI或BF与MVPA之间的负相关关系强于BMI或BF与久坐或轻活动能量消耗比例之间的正相关关系(r(MPA) = -0.45 ~ -0.67/r(MVPA) = -0.51 ~ -0.66 /r（久坐）= 0.33 ~ 0.52/r（轻活动）= 0.36 ~ 0.47；P < 0.001)。结论：这些发现强调了MPA和MVPA对维持正常体重的重要性。(C) 2015年亚洲大洋洲肥胖研究协会。ElsevierLtd.出版。版权所有。
Purpose: The purpose of this study was to examine differences in total daily energy expenditure (TDEE), energy expenditure in various intensities, as well as total daily energy intake (TDEI) and diet quality in normal weight, overweight and obese men and women. Further, the association of energy expenditure and energy intake with body fatness was examined.Methods: The cross-sectional analysis included 430 adults (27.7 +/- 3.8 years; 49.3% male). Body weight and height were measured according to standard procedures and percent body fat (BF) was assessed via dual X-ray absorptiometry. Energy expenditure was determined via the SenseWear Armband. Energy intake and the Healthy Eating Index (HEI) were calculated based on multiple 24-h recalls.Results: Weight adjusted TDEI and TDEE were significantly lower in overweight and obese adults compared to their normal weight peers (p < 0.001) and obese women had a lower HEI (p = 0.006). Overweight and obese adults further displayed a higher proportion of energy expenditure spent in sedentary and in light activities (p < 0.001), while the proportion of energy expenditure in moderate-to-vigorous physical activity (MVPA) was lower compared to their normal weight peers (p < 0.001). The inverse relationship between BMI or BF and MVPA was stronger than the positive association between BMI or BF and the proportion of energy expended in sedentary or light pursuits (r(MPA) = -0.45 to -0.67/r(MVPA) = -0.51 to -0.66 vs. r(Sedentary) = 0.33 to 0.52/r(light) = 0.36 to 0.47; p < 0.001).Conclusions: These findings emphasise the importance of MPA and bouts of MVPA regarding the maintenance of a normal body weight.
