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.

AbstractObjectivesThe combination of sleep duration, television (TV) time and body mass index (BMI) may be related to the alteration of cardiometabolic risk. However, there are few studies that use these variables grouped, and showing the moderating role of age. This study aimed to verify if the combination of sleep duration, TV time and BMI is associated with cardiometabolic risk and the moderating role of age in this relationship in youth.MethodsCross-sectional study conducted with 1411 adolescents (611 male), aged 10–17 years. Sleep duration, TV time and BMI were assessed and grouped into eight categories. Cardiometabolic risk was assessed by a continuous metabolic risk score, including the following variables: low HDL-cholesterol, elevated triglycerides, dysglycemia, high systolic blood pressure, high waist circumference and low cardiorespiratory fitness. Generalized linear models were used to test moderation of age in the relationship between the eight categories of sleep duration/television time/BMI with cardiometabolic risk.ResultsCardiometabolic risk factor showed association with all overweight or obesity independent of sleep time and TV time. Age moderated the relationship between sleep duration/television time/BMI with cardiometabolic risk. This association was stronger in younger adolescents (11 and 13 years), indicating that individuals with inadequate sleep, prolonged TV time and overweight/obesity present higher cardiometabolic risk values when compared to 15-year-old adolescents.ConclusionOverweight/obesity, independently of sleep duration and TV time, is the main risk factor for cardiometabolic disorders in adolescence. When moderated by age, younger adolescents that presented the combination of risk factors had higher cardiometabolic risk.

Practical Implications

The aim of the study was to test the associations between the self-reported access to exercise in green spaces (GS) and moderate-to-vigorous physical activity (MVPA) testing the mediating role of the motivation. Based on self-determination theory (SDT), we expected that self-determined motivation will mediate the associations between the self-reported availability of GS for exercising (GSE) and MVPA with the most self-determined exercise regulation forms (identified and intrinsic motivation) demonstrating the strongest positive associations between the variables. Method: The sample consisted of 2154 participants (74.7% women). The ages ranged from 18 to 79 years, with a mean age of 32.6 (SD = 12.2) years. Participants completed the Behavior Regulation in Exercise Questionnaire-2, the measures of self-reported distance to residential GS (RGS), availability of the GS for exercising (GSE), and physical activity (PA). Logistic regression and path analysis were used to test the associations between study variables. Results: Higher reported distance to RGS was associated with lower reported availability of GSE, but not PA. Availability of GSE was directly associated with more frequent MVPA. More autonomous forms of exercise behavior regulation (intrinsic and identified regulations) mediated the associations between self-reported availability of GSE and MVPA. Internal and identified exercise regulations were directly associated with more frequent MVPA. Conclusions: The results of the present study support the main tenets of SDT suggesting that self-determined behavioral exercise regulation is an important mediator between the self-reported availability of GSE and general MVPA. Practical implications of these findings are discussed herein.

Abstract Background Chronic pain in all its forms and the accompanying level of disability is a healthcare crisis that reaches epidemic proportions and is considered a world level crisis. Chronic non-specific low back pain contributes a significant proportion of chronic pain. Specific psychosocial factors and their influence on reported disability in a chronic non-specific low back pain (CNLBP) population was researched. Methods Psychosocial factors examined include fear, catastrophizing, depression, and pain self-efficacy. This cross-sectional correlational study examined the mediating role between pain self-efficacy and the specific psychosocial factors with reported disability. The study included 90 participants with CNLBP between 20 and 60 years of age. Participants completed the Fear Avoidance Belief Questionnaire, The Pain Catastrophizing Scale, The Patient Health Questionnaire-9, The Pain Self-Efficacy Questionnaire, and The Lumbar Oswestry Disability Index to measure fear of physical activity, pain catastrophizing, depression, pain self-efficacy, and reported disability, respectively. The study used multivariate regression and mediation analyses. Results The principal finding of the study was a strong inverse relationship between pain self-efficacy and reported disability. Further, pain self-efficacy was considered a statistic mediator for all psychosocial factors investigated within this data set. Pain self-efficacy was strongly considered to have a mediating role between reported fear of physical activity and disability, reported pain catastrophizing and disability, and reported depression and disability. Additionally, adjusting for age and reported pain levels proved to be statistically significant, and it did not alter the role of pain self-efficacy. Conclusion The results identified that pain self-efficacy had a mediating role in the relationship between the specific psychosocial factors of fear, catastrophizing, and depression and reported disability. Pain self-efficacy plays a more significant role in the relationships between specific psychosocial factors and reported disability with CNLBP than previously considered.
