Twenty-four pregnant Asian women resident in Singapore were tested for the determination of energy cost of rest and various common daily activities. The average daily energy expenditure was estimated from a diary of activities of seven days. The average daily energy intake was computed from Food Tables on the basis of consumption of measured dressed raw materials of food over seven days in the same period of measurement of energy expenditure. The average daily energy intake and expenditure in this group of pregnant women were found to be 2020 and 1810 kcal (8.5 and 7.6 MJ) giving a balance of +210 kcal (0.9 MJ) per day.
对居住在新加坡的24名亚洲孕妇进行了测试，以确定休息及各种常见日常活动的能量消耗。根据一份七天的活动日记估算平均每日能量消耗。在测量能量消耗的同一时期，根据七天内食用的经测量的生鲜食材消耗量，依据食物表计算平均每日能量摄入量。结果发现，这组孕妇的平均每日能量摄入量和消耗量分别为2020千卡和1810千卡（8.5兆焦和7.6兆焦），每天能量平衡为+210千卡（0.9兆焦）。
