ObjectiveThe aim of this study was to identify chronotypes of medical students at the Federal University of Paraíba (UFPB) and its relationship to quality of sleep, daytime sleepiness, age, sex and season of birth.MethodsThe final sample consisted of 221 students, assessed by four questionnaires: demographic questionnaire, Morningness–Eveningness Questionnaire (MEQ), Pittsburgh Sleep Quality lndex (PSQI) and Epworth Sleepiness Scale (ESS).ResultsThere was a statistically significant difference between groups with respect to chronotypes and PSQI score (p<0.0005), but not with excessive daytime sleepiness. A significant negative correlation was found between the scores of MEQ and PSQI (rho=−0.3, p<0.0005), demonstrating that the greater the eveningness, the worse the sleep quality. It was observed that 51.6% of students were classified as indifferent chronotype, 61.5% had poor quality of sleep, while 42.1% had excessive daytime sleepiness. Sex and season at birth did not differ between chronotypes.ConclusionThese findings demonstrate that the evening chronotype was associated with poor quality of sleep in medical students, but not with increased daytime sleepiness, with potential impairment to their academic performance and quality of life.

BACKGROUND Based on personal observations of dermatologists, nutritionists and patients, a new problem emerges in the gyms: development and exacerbation of acne in users of whey protein, which is a protein derived from cow's milk. Whey Protein extract contains growth factors that may be related to acne. Its purity and composition are not fully known and there is no scientific research on its potential to cause acne. OBJECTIVES Assess the relationship between the use of proteincalorie supplements and onset or exacerbation of acne vulgaris in young adults in the city of João Pessoa. METHODS Descriptive observational study conducted in gyms and in a dermatology clinic. Each participant was examined for acne on three occasions and followed for 60 days. RESULTS 30 patients were examined. Onset or exacerbation of acneiform lesions were observed (p <0.0005). The effect was more prominent in females and in individuals without current acne and no family history of acne. CONCLUSION This study showed the onset of acne with the progressive use of protein-calorie supplementation, in a two-month period. It is suggested that this type of supplementation be discouraged.
