“…Thus, considering that this is a categorical variable, there is no need for normality testing since the variable was dichotomized. Given the lack of consensus regarding national guidelines for classifying sleep duration in children and adolescents [20], the responses obtained were dichotomized into <8 hours of sleep and >8 hours of sleep, according to the National Sleep Foundation [8] and national studies [9,20].…”

“…There are several studies in the literature addressing the relationship between sleep duration and excess body adiposity [3,9,12,15]. However, few studies have investigated using same model of analysis the concurrent presence of sleep duration and body adiposity, despite the evidence of the interrelationship between these factors [1-4].…”

Objective This study estimated the combined prevalence of insufficient number of hours of sleep per day and excess body adiposity among young students. The sociodemographic and behavioral characteristics associated with this concurrent health conditions were investigated. Methods This is a cross-sectional school-based study of 975 participants aged 11-14 years in Florianópolis, Santa Catarina state, Brazil. Body adiposity was assessed based on tricipital and subscapular skinfold measurements and classified according to Lohman. The total number of hours of sleep per day was reported by the students’ parents/guardians, and it was classified as follows: as <8 hours per day and ≥8 hours per day. Data on sociodemographic characteristics, food consumption, and physical activity were collected using a self-administered questionnaire. The chi-square test and multinomial logistic regression with a 5% significance level were used to evaluate the association between the variables. Results The combined prevalence of insufficient number of hours of sleep per day and excess body adiposity was 25.1% (CI95%:20.7-29.9). The sociodemographic and behavioral factors predictive of these conditions were as follows: 13-14 year age group and household monthly income in the intermediate tertile. Conclusion The concurrent presence of insufficient sleep and excess body adiposity was found in a little more than a quarter of the students investigated. The population subgroups belonging to the 13-14 year age group and intermediate tertile of income were more likely to have concurrent insufficient number of hours of sleep per day and excess body adiposity.

“…[2] The sleep has an special importance due to the effect of sleep deprivation on the quality of life, which has been pointed out as cause of several neuro-behavioral deficits, such as mood alteration; memory lapses; reduction of cognitive performance, vitality and sensation of happiness. [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.…”
