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.

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.

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.

Mediating Role

Background/Aims: When people hone their emotional skills, they become better at manipulating others. They use their emotional skills for coping with the demands of life. This study investigated the mediating role of moral disengagement between emotional manipulation and psychological well-being. Further, the moderating role of age is tested for the mediation model of the study. Methods: This study has a cross-sectional design. Participants included students from private and public institutions (n = 542; Mean age = 18.59 years, SD = 2.10 years; gender = 46% males). Responses were collected on emotional manipulation, moral disengagement, and psychological well-being questionnaires. Analyses were conducted using SPSS 21 and PROCESS 3.1. Results: The correlation analysis showed that both in late adolescents and young adults, moral disengagement negatively correlated with psychological well-being. However, the correlation is much stronger for young adults as compared to late adolescents. Similarly, emotional manipulation has a stronger positive correlation with moral disengagement in young adults compared to late adolescents. Results also showed that moral disengagement and emotional manipulation is higher in males than females, and psychological well-being is higher in females than males. Moral disengagement appeared to be a negative mediator for the relationship between emotional manipulation and psychological well-being. Further, age moderated the indirect effect of emotional manipulation on psychological well-being through moral disengagement. The moderation of age suggests that young adults are more inclined toward moral disengagement behaviors for manipulating emotions in comparison to late adolescents. Conclusions: It is concluded that use of emotional manipulation is associated with a direct increase in psychological well-being; however, indirect emotional manipulation decreases psychological well-being, with an increased use of moral disengagement. Moreover, this indirect effect is stronger in young adults compared to late adolescents, as young adults are more inclined toward moral disengagement.
