Estimation of energy intakes is required for understanding of growth and disease in young students. This study was conducted to estimate the energy intake of young students and compare with their energy requirements.
In this cross-sectional study, using simple random sampling, 400 students, aged 14-18 years, were selected in 2010. Hariss-Benedict equations were used to estimate the energy requirement of each group.
Mean and standard error of energy intake and requirements of males was 2155 ± 30 and 1670 ± 18, respectively, and of females was 2700 ± 21, 2300 ± 4 kcal, respectively. Differences of means, energy intake, and requirement in both sexes were significant (P < 0.001).
Because of their age (14-18 years), which is called growth age, energy intake was lower than their needs.
为了解青年学生的生长发育及疾病情况,需要对其能量摄入进行评估。本研究旨在评估青年学生的能量摄入,并与他们的能量需求进行比较。
在这项横断面研究中,2010年采用简单随机抽样法选取了400名年龄在14 - 18岁的学生。使用哈里斯 - 本尼迪克特方程估算每组学生的能量需求。
男性能量摄入和需求的均值及标准误分别为2155 ± 30和1670 ± 18,女性分别为2700 ± 21、2300 ± 4千卡。男女在能量摄入和需求均值上的差异均具有显著性(P < 0.001)。
由于他们处于14 - 18岁这个被称为生长年龄的阶段,能量摄入低于其需求。
