Correlação entre indicadores antropométricos e a qualidade do sono de universitários brasileiros

Abstract

RESUMOObjetivou-se investigar a correlação existente entre indicadores antropométricos e a qualidade do sono de universitários brasileiros por meio do Índice de Qualidade do Sono de Pittsburgh. Estudo transversal, realizado com 702 universitários entre março de 2010 e junho de 2011. A correlação indicou que os casos de obesidade foram maiores entre os estudantes bons dormidores. Por outro lado, o sobrepeso e os valores elevados das circunferências cervical e abdominal predominaram entre os maus dormidores. Assim, além dos prejuízos ocasionados pelos distúrbios do sono isoladamente, ressaltam-se riscos adicionais devido à associação da má qualidade de sono com o sobrepeso, a obesidade central e a elevação do perímetro cervical. DESCRITORESTranstornos do sono Estudantes Obesidade Saúde do adulto ABSTRACTThe current study investigated the correlation between anthropometric indicators and sleep quality among Brazilian university students using the Pittsburgh Sleep Quality Index. A cross-sectional assessment with 702 university students was conducted between March 2010 and June 2011. Results showed that cases of obesity were more frequent among students who were good sleepers. On the other hand, overweight and high cervical and abdominal circumference was most prominent among poor sleepers. Thus, apart from the damage caused by sleep disorders alone, additional risks due to the association between poor sleep quality and being overweight, central obesity, and increased cervical perimeter are highlighted.

Estudio transversal, realizado en 702 estudiantes universitarios entre marzo de 2010 y junio de 2011. La correlación indicó que los casos de obesidad fueron mayores entre los estudiantes que dormían bien. Por otra parte, el sobrepeso y elevados valores de circunferencia cervical y abdominal fueron predominantes entre los que dormían poco. Así, además de los daños causados por los trastornos del sueño, aisladamente, se resaltan los riesgos adicionales debido a la asociación de la mala calidad del sueño con el sobrepeso, la obesidad central y el aumento del perímetro cervical. DESCRIPTORES INTRODUCTIONIn recent decades, the introduction of new technologies has transformed cultural habits and lifestyles among university students around the world. However, this has contributed to the development of sleep disorders among these young adults (1) . Although poor sleep quality is common among the elderly (2) and nightshift workers (3) , recent research has shown that university students have also been affected, both nationally (4) and internationally (5) .In general, sleep disorders carry various implications including, but not limited to, a loss in quality of life, autonomic dysfunction, decreased academic and professional performance, and increased inc...

Sleep quality of Brazilian nursing students: A cross-sectional study

“…Based on this, we can understand why nursing students get unhealthy habits that affect their health during the course. The investigated sample was mostly composed for females, corroborating with investigations involving university students, [5,8,9,12,14,19] especially on nursing field [6,7,15] which has been characterized as a female profession once the notable number of women working in nursing. [20] Regarding the age range, there was a prevalence of young adults and single students, what was also verified in other investigations with nursing students [6,12] and in university students from other courses.…”

“…[21] However in this study, on the daily disturbances, most students never had difficulty to stay awake in the last month, differently of results found in an investigation took with nursing students and those from other areas. [9] Also, most of them reported indisposition or lack of enthusiasm to perform daily activities.…”

“…We found the predominance of university students who did not use medication to sleep, what corroborate with findings from several studies. [6,7,9,25] Regarding the sleep disturbances, the factor that most interfered on this domain were: waking up in the middle of night or early, feeling very hot and having nightmares. It may be related to the site where these students live-the northwest of Brazil.…”

“…[4] Among the social groups vulnerable to changes in the sleep pattern, the most noteworthy are university students who, upon starting the course, interact with several factors that may be associated with their sleep deprivation. Among these factors, the most important are those associated with the time dedicated to academic activities; [5][6][7][8][9][10] working in the other shift; [11] excessive use of social media, mobiles and television; [12] consumption of alcoholic beverages; [13] and demographic factors, such as sex, age and marital status conjugal. [6,14] Although the existence of investigations on sleep quality in nursing students confirm they are poor sleepers, [5,6,15] these researches were conducted in a few Brazilian states, with small samples that considered only the two first semesters students [15] or incoming and outgoing students.…”

Sleep Duration, Sleep Quality, Body Mass Index, and Waist Circumference among Young Adults from 24 Low- and Middle-Income and Two High-Income Countries

“…This may be especially important among young adults, including university students, because of accompanying lifestyle changes such sleep patterns, as well as dietary and physical activity behaviour taking place in the transition from home to university [13]. This may help in distinguishing obesity factors determined by biological and socio-environmental factors, which are needed in culturally appropriate obesity prevention strategies [12].…”
