Evaluation of the relationship between sleep quality and night eating behavior and body mass index in adult women

The aim of this study was to investigate the relationship between body mass index and the quality of sleep in 70 adult women aged 20-60 years. Demographic characteristics, anthropometric measurements, nutritional status and health status of the subjects were questioned by a questionnaire. The Sleep Quality Index (PSQI) was used for the evaluation of sleep quality, and the Night Eating Questionnaire (GYA) was used for the presence of NES and 1 day of food consumption was recorded to determine the daily energy and nutrient intake. SPSS 20 program was used for statistical analysis. Descriptive statistical methods (frequency, ratio, mean, standard deviation) and Mann-Whitney U Test, T Test in Independent Groups and Pearson Chi-Square Analysis were used to evaluate the findings. The mean BMI of individuals was 28,07 ± 5,08 kg / m². 54.3% of the participants had poor sleep quality and 10% had Night Eating Syndrome (NES). There was no significant relationship between NES and sleep quality and BMI (p>0.05). Night eating scores were found to be statistically higher in the poor sleep quality group (p<0.05). Good and bad quality of sleep in food groups were compared to intake; Energy, carbohydrate, saturated fatty acid and folate averages were significantly higher in the poor sleep quality group (p<0.05). Energy, carbohydrate protein, thiamine, biotin, tryptophan, zinc, iron and phosphorus were found to be significantly higher in group with NES than group without NES (p<0.05). It was observed that sleep quality and night-eating status were interrelated and affect nutritional status. More comprehensive studies are needed.
