Abstract Background Obesity and short sleep duration have both been related to endocrine and metabolic alterations, type II diabetes mellitus, life-threating cardiovascular diseases, and impaired daytime functioning and mood. However, the bidirectional relationship between these conditions and underlying mechanisms still remain unclear, especially in young adults. Objective This cross-sectional study therefore was aimed at elucidating the potential association of anthropometric and body composition parameters with objective and subjective sleep duration and quality in young sedentary adults, considering the potential mediating role of objectively-measured sedentariness, physical activity, and diet. Methods A total of 187 adults aged 18-25 (35.29% men) were included in the study. Body mass index (BMI) and waist-hip ratio were calculated through weight, height, waist and hip circumferences measures. Dual-energy X-ray absorptiometry scanner was used to assess body composition parameters such as lean mass index, fat mass index and visceral adipose tissue mass. Sedentary time, physical activity, and sleep duration and quality were objectively measured using accelerometry, sleep quality also being subjectively measured with the Pittsburgh Sleep Quality Index. Dietary intake was assessed by means of 24h recall questionnaires. Results BMI, waist-hip ratio and lean mass index were inversely associated to objectively-measured total sleep time and sleep efficiency (p < 0.05). Sedentary time moderated by sex explained the effects of BMI on total sleep time such that a high BMI was related to higher sedentariness in men which, in turn, was significantly associated with shorter sleep duration. Discussion Sedentary time is a link-risk factor mediating the adverse consequences of high BMI on short sleep duration in healthy young men. However, not until the complex association between body composition and sleep in young population is properly understood will it be possible to establish appropriate therapeutic goals addressing the early morbidity and mortality that obesity and short sleep duration certainly determine.

Obesity and sleep disturbances are both related to endocrine and metabolic alterations, cardiovascular disease, and impaired daytime functioning and mood. However, the bidirectional relationship between these conditions and the underlying mechanisms still remain unclear. This study aimed to investigate the potential association of anthropometric and body composition parameters with sleep in young adults, considering the mediating role of sedentariness, physical activity, and diet. A total of 187 adults aged 18–25 (35.29% men) participated in the study. Body mass index (BMI), waist–hip ratio, and waist–height ratio were calculated, and a dual-energy X-ray absorptiometry scanner was used to assess body composition. Sedentary time and physical activity, as well as sleep duration and quality, were objectively and subjectively measured using accelerometry and the Pittsburgh Sleep Quality Index. An inverse association was found between BMI and total sleep time (β = −0.165, p = 0.029). Waist–hip ratio and lean mass index were also negatively associated with total sleep time (β = −0.222, p = 0.007, and β = −0.219, p = 0.004) and sleep efficiency (β = −0.174, p = 0.037, and β = −0.188, p = 0.013). Sedentary time moderated by sex explained the association of BMI with total sleep time such that a high BMI was related to higher sedentariness in men which, in turn, was significantly associated with shorter sleep duration. Sedentary time is, therefore, a link/risk factor mediating the association of high BMI with short sleep duration in healthy young men.

The main purpose of the study was to explore the associations of sleep duration and sleep quality with physical activity (PA). In this cross-sectional study, participants were 894 elderly individuals (mean age 80 ± 3 years; 56.0% women) living in nursing homes. PA, sleep duration, and sleep quality (based on the Pittsburgh Sleep Quality Index (PSQI)) were self-reported. The associations of sleep duration and sleep quality with PA at the nursing home level were analyzed using generalized estimating equations with clustering. Participants reporting short sleep duration (<6 h; OR = 0.45; 95% CI 0.25–0.80) were less likely to report sufficient PA, yet those reporting long sleep duration (>9 h; OR = 2.61; 95% CI 1.35–5.02) and good sleep quality (<5 points; OR = 1.59; 95% CI 1.19–2.12) were more likely to report sufficient PA. When sleep duration and sleep quality were entered into the same model, the same associations remained. This study shows that elderly individuals who report short sleep duration are less likely to meet PA guidelines, while those who report long sleep duration and good sleep quality are more likely to meet PA guidelines. Strategies aiming to improve sleep duration and sleep quality are warranted.

ObjectiveAssociations between self-reported sleep duration and obesity indices in children are well recognised; however, there are no studies on associations between objectively measured other sleep parameters and physical activity with body composition in preschoolers. Therefore, the aim of this study was to determine the associations between sleep parameters and moderate-to-vigorous physical activity (MVPA) with body composition indices in preschoolers using objective measures.DesignA cross-sectional study.ParticipantsThe study group consisted of 676 children aged 5–6 years, who were enrolled in kindergartens in the 2017/2018 school year.Outcome measuresSleep parameters and MVPA were measured using accelerometers for 7 days. Bioelectrical impedance analysis was used to estimate body composition.ResultsSleep duration and sleep efficiency were inversely associated with body fat percentage (BFP) (β=−0.013 and β from –0.311 to −0.359, respectively) and body mass index (BMI) (β from −0.005 to −0.006 and from −0.105 to –0.121, respectively), and directly associated with fat-free mass (FFM) (β from 0.010 to 0.011 and from 0.245 to 0.271, respectively) and muscle mass (β from 0.012 to 0.012 and from 0.277 to 0.307, respectively) in unadjusted and adjusted models. BFP was inversely associated with MVPA and positively associated with number of awakenings and sleep periods. Number of sleep periods was inversely associated with FFM, and positively with BMI and muscle mass. Correlation matrix indicated significant correlation between BFP, FFM and muscle mass with sleep duration, sleep efficiency, number of sleep periods and MVPA.ConclusionsPeriodic assessment of sleep parameters and MVPA in relation to body composition in preschool children may be considered, especially in those who are at risk for obesity.

BackgroundInsomnia is a highly prevalent complaint, largely associated with mental disease. Clinical evidence classifies insomnia in 2 subtypes: with sleep misperception (WSM) and without sleep misperception (wSM). That presents distinctive pathophysiologic pathways and different public health implications.ObjectivesDescribe the main differences between primary insomnia WSM and wSM regarding:– clinical features;– diagnosis;– management;– implications.MethodsWe conducted a systematic review. PubMed, Embase and PsycInfo were searched from 2000–2016. The reference lists of systematic reviews, narrative synthesis and some important articles were included. Following the inclusion criteria, we selected 25 studies from 59 articles.ResultsThe prevalence of sleep-state misperception in primary insomniacs (total sleep time > 6.5 h and sleep efficiency > 85%) is around 26%. Insomniacs with normal sleep duration showed a profile of high depression and anxiety and low ego strength, whereas insomniacs with short sleep duration showed a profile of a medical disorder.Cortical hyperarousal is higher in insomniacs and could be related to an alteration in sleep protection mechanisms. The sleep architecture was relatively normal for the WSM comparing with the group wSM. Risk of cardiometabolic, neurocognitive morbidity and mortality, and responses to treatment are different between these two insomnia phenotypes. Patients with short sleep duration may respond better to biological treatments, whereas insomnia with normal sleep duration may respond primarily to psychological therapies.ConclusionsThe clinical characteristics of patients with sleep-state misperception differed from those without this condition. Available research related to these conditions is expanding rapidly, but many questions remain unanswered.Disclosure of interestThe authors have not supplied their declaration of competing interest.

In the European Union, Czech Republic ranks 3rd and 6th for the incidence of obesity and cardiovascular diseases, respectively. Worldwide, short sleep duration and excessive daytime sleepiness (EDS) characterize obese subjects, which in turn exhibit scarce physical activity and unhealthy diet. We aimed to understand the relationship between irregular sleep patterns, obesity and lifestyle factors, such as diet and physical activity, in a vulnerable Czech population. 1482 members of the Kardiovize cohort, a random sample of the Czech urban population, were included in a cross-sectional study. Exposure variables included self-reported sleep duration and EDS, assessed by the Epworth Sleepiness Scale. Primary outcomes were BMI and waist-to-hip ratio or prevalence of obesity and central obesity. Covariates included physical activity and diet. Associations and interactions between variables were evaluated using logistic regression analyses. After adjustment for covariates, short sleep duration (<7 h) was associated with greater odds of overweight (BMI > 25; OR = 1.42; 95%CI = 1.06–1.90; p = 0.020) and obesity (BMI > 30; OR = 1.40; 95%CI = 1.02–1.94; p = 0.047), while EDS was associated with greater odds of central obesity (OR = 1.72; 95%CI = 1.06–2.79; p = 0.030), independent of diet and physical activity. However, due to the cross-sectional nature of our study, further prospective, large-scale studies are needed to evaluate the etiological link and causality between sleep disturbances and obesity.
