Association of Excessive Daytime Sleepiness with Anthropometric and Cardiovascular parameters


Sleep is defined as a state of temporary loss of consciousness from which an individual may be awakened naturally or through endogenous mechanisms which regulate the cyrcadian rhythm. Sleep disorders may generate disturbances in quality of life. Some external factors may cause restrictions and sleep fragmentation. Studies correlate sleep disorders to diabetes mellitus, arterial hypertension and obesity, as well as to their worsening. Stressful factors tend to decrease the amount of sleep and to desyncronize the sleep-wake cycle, resulting in decreased quality of sleep and, sometimes, in excessive daytime sleepiness (EDS). In regards to medical students, anxiety due to the aproval and access to medical school and later due to scenarios in which they deal with matters related to sickness, suffering and death, besides the prospects of entering the job market, make them vulnerable to sleep disorders. Considering the aforementioned aspects, this work intends to demonstrate how medical students may be affected in their routines during their professional qualification.


To analyse if anthropometric and cardiovascular parameters differ between different degrees of excessive daytime sleepiness.


Observational, descriptive and analytical study submitted to the Commitee of Ethics and Research (N.3.168.630). The sample totalized 77 undergraduate medical students from the first and last two years of the course. Socio-demographic and anthropometric data was gathered (height and weight for BMI calculation, neck circumference, abdominal circumference, arterial pressure and heart rate and the Epworth Sleepiness Scale (ESS) was used to evaluate excessive daytime sleepiness. The analyses and statistic tests were done in the program R Commander (Rx64 3.6.0). Values of p<0.05 were considered significant.


Answer variables: EDS with arrive at home/min (Kruskal-Wallis P<0.03). GENDER with physical activity (qui- sq p<0.06)/ (Wilcoxon P<0.001)/ (Test t Student p<0.001)/ PAS (Wilcoxon p<0.01)/ PAD (Test t Student p<0.01). AGE with arrive at home/min (Kruskal-Wallis p<0.06)/ IMC (ANOVA p<0.02)/ Interval between the beginning and end of graduation (Fisher p<0.001).


Considering that these students may present risk factors for the development of an irregular sleep-wake cycle, it is necessary to intensify studies about excessive daytime sleepiness in order to prevent sleep disorders.
