بررسی ارتباط مصرف درشت مغذی‌ها و ریزمغذی‌ها با کیفیت خواب در نوجوانان

Background and purpose: Sleep plays a major role in maintaining health and improving academic performance and behavior in adolescents. Studies on the relationship between diet and sleep quality are not consistent. The aim of this study was to investigate the association between sleep quality and consumption of macronutrients and micronutrients in adolescents. Materials and methods: A cross-sectional study was conducted in 319 individuals (10-18 years of age) selected by multistage random cluster sampling in Minoodar district, Qazvin, Iran 2010-2011. Dietary pattern was assessed using food frequency questionnaire (FFQ) and information on food intake was obtained using Nutrition 4, Version 3.5.2. Sleep quality was assessed by BEARS questionnaire. Data analysis was performed applying T-test. Results: The research population included 162 (50.8%) females. The mean age of the participants was 15±2.43 years. Amon the cases studied 302 were found with low-quality sleep. There was no significant relationship between sleep quality and calorie, and intake of micronutrients and macronutrient (P>0.05). The mean intake of omega-3 fatty acids in subjects with good-quality sleep was higher than that in the subjects with low-quality sleep (P≤0.05). Conclusion: Appropriate intake of omega-3 fatty acid was associated with high-quality sleep. There was no relationship between sleep quality and consumption of micronutrients and macronutrients.
