This report describes associations between subjective measures of sleepiness, eating disturbances and body mass index in female university students.520 females (mean=19.3years, sd=1.31), completed a series of questionnaires that assessed eating behaviours (Eating Attitudes Test-25), arousability, coping, emotional expressivity, worry, neuroticism/extraversion, perceived physical/mental health, academic stress, positive/negative affect, pre-sleep arousal (cognitive/somatic), body mass index (BMI; KG/M2) and sleep-wake aspects including subjective sleep propensity/Epworth Sleepiness Scale (ESS) and perceived daytime sleepiness (PDS, four items: feel excessively sleepy during the day, being sleepy during the day is a problem, feel performance is impaired due to daytime sleepiness, feel the need to nap during the day).ESS and PDS correlated moderately with each other (r=.415, p<001). EAT-25 mean score was 24.25 (sd=14.2). BMI mean score was of 20.7 (sd=2.39; range=14.5–34.7). 14,7% were classified as underweight (BMI<18.5), 81.8% normal weight (BMI of 18.5–24.9), 2.9% overweight (BMI of 25.0–29), and 0,6 obese (BMI⩾30.0). Most students had very/good mental (75.7%) and physical health (82.7%). Logistic Regression analyses models showed that perceived daytime sleepiness/PDS (but not sleep propensity/ESS) and self-reported usual sleep duration were independent significant predictors of global eating disturbance (Odds ratio/OR=.57; p=.049). Daytime sleep propensity, perceived daytime sleepiness, and perceived physical health were independent significant predictors of high BMI (respectively, OR=1.58; p=.004; OR=0.62; p=.046; OR=0.034; p=.002). Neither subjective sleep quality nor usual sleep duration were associated with BMI.In young females, daytime sleep propensity/perceived sleepiness and perceived physical health were predictors of higher BMI. Perceived daytime sleepiness and usual sleep duration were both predictors of global disordered eating behaviours/attitudes.
