ABSTRACT: A cross-sectional descriptive study of body composition and resting energy expenditure (REE) of 312 adolescents (155 boys and 157 girls) was conducted in five state high schools in Yangon, Myanmar. The body composition was measured by anthropometry and resting energy expenditure was determined by indirect calorimetry method. Although statistically not significant, mean body mass index (BMI) of 12, 13 and 14 year-old girls was greater than that of age-matched boys (16.06 ± 2.98 vs 15.09 ± 2.56, 16.97 ± 2.60 vs 15.68 ± 2.30 and 17.18 ± 2.38 vs 16.77 ± 2.69 respectively). Mean lean body mass (LBM) of 12- year-old girls was greater than that of the boys (26.81 ± 5.32 kg vs 25.91 ± 5.18 kg) but 14- year-old boys has greater LBM than that of the girls (37.33 ± 11.75 kg vs 31.35 ± 4.61 kg). Mean body fat percentage of the girls was significantly (p < 0.01) greater than that of the boys in all age groups (21.08 ± 4.31% vs 13.14 ± 4.30%, 21.85 ± 3.77% vs 13.47 ± 9.11% and 22.37 ± 3.96% vs 13.50 ± 4.19% respectively). Mean resting energy expenditures (REE) of 12, 13 and 14 -year-old boys were 1193.90 ± 195.49 kcal/d, 1239.82 ± 180.60 kcal/d and 1438.35 ± 258.83 kcal/d respectively and those of the girls were 1164.09 ± 215.75 kcal/d, 1192.89 ± 159.13 kcal/d and 1212.61 ± 151.08 kcal/d respectively. These data will serve as a base-line data of current nutritional and metabolic status of adolescents in Yangon, Myanmar.
