Đặc điểm nhân trắc và cấu trúc cơ thể của trẻ 11 - 14 tuổi tại trường phổ thông dân tộc bán trú tại một số huyện miền núi, tỉnh Điện Biên, năm 2018

A cross-sectional study was conducted on 4,069 children among 11–14-year-old from semi-boarding schools in Dien Bien province in 2018 to describe the anthropometric and body composition characteristics. Results showed that the mean weight and height of boys respectively by age groups (11, 12, 13, 14 years old) were (28.6±4.9 kg, 32.2±5.9 kg, 36.3±6.4 kg, 42.3±6.9 kg); (132.4±7.3 cm, 138.2±8.2 cm, 144.5±8.3 cm, 152.0±7.7 cm) and girls (30.3±5.4 kg, 34.7±5.8 kg, 39.7±6.2 kg, 42.7±5.6 kg); (135.2±7.4 cm, 140.5±6.8 cm, 145.6±6.1 cm, 147.8±4.4 cm) The height of girls at 11-12 was statistically significant higher than that of boys, but this indicator was opposite in the age group of 13-14. The mean height for age Zscore boys was -1.94 ± 1.08 and for girls was -1.89 ± 0.97, close to the identified threshold as stunting. The mean of the total body fat percentage (%BF) and fat mass (FM) gradually increased and was significantly different among the age group in girls (p<0.001). From the above results, we can provide data on the anthropometric status of children in ethnic minority areas, the change of children's body composition according to age and gender.
