Objective To measure the daily energy expenditure of aircrews so as to provide data for studies on energy metabolism and to explore a new method to monitor energy expenditure for aircrews.Methods The total daily energy expenditure of 59 aircrews from 4 aviation units was calculated via life observation and actigraphy.The differences and correlations between the two methods were observed.Results The total daily energy expenditure measured by means of life observation and actigraphy was(3 102.1±372.4)kcal and(2 957.8±422.2)kcal,respectively.There was statistically significant difference between the two methods(t=3.170,P=0.002),but strong correlations were also found between the two methods(r=0.619,P＜0.001).Conclusion The results of measurement by life observation and actigraphy are closely correlated.Actigraphy can replace life observation in measurement of the total energy expenditure of aircrews.
