Abstract:
The basal metabolism of 156 healthy preschool children aged from 5-6 with 71 males and 85 females living in sub-tropic conditions are carefully measured over four seasons in a whole year continuously.The measurements using open circular method with specialmade mask and Douglas bag for gas collections and the analysis of expired air using Beckman OM-11 and LB-2 apparatus are made. The BMR results are:(1) BMR on average in a year for boys is 45.5 ?3.08 kcal.m-2.h-1 or 1.97?0.17 kcal.kg-1.h-1 or 34.1?3.01 kcal/h, and 43.2?2.65 kcal.m-2.h-1 or 1.89?0.17 kcal.kg-1.h-1 or 32.0?2.99 kcal/h for the girls. There are significant differences for BMR among seasons in both sex, a higher BMR in cold weather and a lower in summer-autumn season, 4% for boys and 3% for girls of the BMR change between those extreme climates; (2) There is significant difference in BMR between boys and girls,the latter 5% lower than the former; (3) The correlations of the BMR with body weight and the body surface are significant statistically but not with pulse or respiratory rate. The results are discussed.
