Evaluation of the Relationship Between the Amount and Type of Carbohydrate Consumed After the Evening Meal and Sleep Quality

Abstract

Aim The aim of this study is to evaluate the relationship between the amount and type of carbohydrates consumed after evening meal and sleep quality. Method This study was conducted on 177 university students with an average age of 21. A general information questionnaire, 24-hour dietary recall, and Pittssburgh Sleep Quality Index (PSQI) questionnaire were applied to the participants. Body composition were determined with the TANITA DC 360 ST device using the bioelectrical impedance analysis (BIA) method. Height, waist-hip circumference was measured with a non-stretchable tape measure. Nutritional record data were recorded in BEBIS program. Final analysis of the study was done by SPSS Inc. Made with Chicago IL v21 program. Results The average PSQI score of the participants was 7.14. While 18.1% of the participants had good sleep quality (PSQI≤5), 81.9% had poor sleep quality (PSQI>5). No significant correlation was found between the amount of carbohydrates consumed after the evening meal and sleep quality (p>0.05). However, a significant correlation was observed between the percentage of carbohydrates, absorbable oligosaccharide consumption and PSQI score (p=0.044, p=0.013, respectively). Also, a significant correlation was found between protein amount, protein percentage and sleep quality (p=0.037, p=0.020, respectively). In addition, a significant correlation between the amount of water consumed after the evening meal and PSQI score was found (p
