<p>Objective:</p><p>A desire for thinness is typically seen among female university students, about 22% of whom can be categorized as underweight. However, poor dietary habits can lead to high body fat percentage. Furthermore, one in six women in their 20s reports experiencing problems with sleep quality or duration and not feeling sufficiently rested upon awakening. Ensuring the quality of sleep time and sleep even on the prevention of obesity is considered to be important. Therefore, the aim of this study was to examine the association between body fat percentage and sleep disorders in young females.</p><p>Methods:</p><p>This study, which consisted of anthropometric and a questionnaire survey regarding sleep health, was conducted in October 2012. Participants comprised 111 female university students (mean age±standard deviation, 19.7±2.11 years) who understood the purpose of the study and provided their consent to participate. Body fat percentage was measured by using a bioelectrical impedance analysis device, subjects were classified into one of two groups (＜28% or ≤28% body fat percentage). Sleep quality was evaluated based on the five factors of the Sleep-Health Risk Index, and additional items were taken from the Healthy cognitive evaluation. Multiple logistic regression analysis was performed to simultaneously examine the relations of several variables on body fat percentage in the ≤28% group.</p><p>Results:</p><p>A total of 71 participants (63%) were classified as having body fat ≥28%. The median scores for sleep apnea and parasomnia were higher in participants in the body fat ≥28% group (1 and 2, respectively) than in participants in the body fat ＜28% group (0 and 1, respectively). Results from multiple logistic regression analysis showed a statistically significant correlation between ≥28% body fat and both a lack of concern about nutrition and eating habits (odds ratio［OR］: 0.37, p＝0.048) and sleep apnea (OR: 2.84, p＝0.010). A significant negative correlation was found between sleep duration and body mass index (BMI) (r＝－0.26, p＝0.041).</p><p>Conclusion:</p><p>The result of this study suggests a significant association was found between ≥28% body fat and sleep apnea in female university students, and that a lack of concern regarding nutrition and eating habits is a risk factor for high body fat percentage. Therefore, nutrition education should be reinforced or supplemented.</p>
