Energy balance study in pregnant Asian women.

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.
