Comparison of energy intake and requirement of young students in Isfahan, Iran

Abstract

• Introduction: Estimation of energy intake is required for understanding of growth and disease of young students. This study was conducted to estimate energy intake of young students and compare with their energy requirements.
• Materials and Methods: In cross-sectional study, using simple random sampling, 400 students, aged 14-18 years were selected in 2010. Hariss-Benedict equations were used to estimate energy requirement of each groups.
• Results: Mean and standard error of energy intake and requirements of male was 2155±30, 1670±18 and 2700±21, 2300±4 Kcal for females. Differences of means, energy intake and requirement in both sex were significant (P<0.001).
• Conclusion: Because of being in 14-18 years, which is called growth age, energy intake was lower than their needs.
• Key words: Energy intake, energy requirements, estimation, physical activity
