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.

The Relationship

The objectives were to clarify whether the relationship between physical performance and frailty was independently and jointly mediated by movement behaviors and body composition. We analyzed 871 older adults (476 women) from The Toledo Study for Healthy Aging. Skeletal muscle index (SMI) and fat index (FI) were determined using bone densitometry. Sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) were assessed using accelerometry. The Frailty Trait Scale and The Short Physical Performance Battery (SPPB) were used to evaluate frailty and physical performance, respectively. Simple and multiple mediation analyses were carried out to determine the role of movement behaviors and body composition, adjusted for potential confounders. ST and MVPA acted independently as mediators in the relationship between SPPB and frailty (0.06% for ST and 16.89% for MVPA). FI also acted as an independent mediator in the same relationship (36.47%), while the mediation role of SMI was not significant. MVPA and FI both acted jointly as mediators in this previous relationship explaining 58.15% of the model. Our data support the fact that interventions should simultaneously encourage the promotion of MVPA and strategies to decrease the FI in order to prevent or treat frailty through physical performance improvement.

The objective of the present study was to estimate whether physical activity (i.e., step counts) on one day was associated with both sleep quality (i.e., sleep efficiency) and quantity (i.e., total sleep time) the following night and to examine to what extent sleep on one night was associated with physical activity the next day. We collected data continuously with a Fitbit Charge 3 among 33 young adults with overweight and obesity participating to a weight management program. A total of 7094 days and nights were analyzed (215 days on average per participants). Person-specific models (i.e., participants were not pooled together) were conducted to test the bi-directional associations for each participant separately. Results from linear regressions and Generalized Additive Models (GAMs) were compared to account for potential non-linearities in associations. Results suggest an absence of association between steps and sleep efficiency in the two directions for most participants [i.e., these associations were not significant for 31 (94%) and 32 (97%) of the participants]. More heterogeneous results were observed for the association between steps and total sleep time, with 19 participants (58%) showing a negative association between total sleep time and next day steps, and 9 (27%) showing a negative association between steps and next day total sleep time (results of the linear regressions). Taken together, these results suggest a potential conflicting association between total sleep time and physical activity in the daily lives of young adults with overweight and obesity.

Prospective Association

Physical activity (PA) is a key contributor in long-term weight management but there remains limited research on the association between weekly PA patterns and weight change. The purpose of the present study was to examine the prospective association between weekly PA patterns and weight change in generally healthy young adults. Anthropometric measurements, including dual X-ray absorptiometry, were obtained every 3 months over a period of one year in 338 adults (53% male). At each measurement time, participants wore a multisensor device for a minimum of 10 days to determine total daily energy expenditure and time spent sleeping, sedentary, in light PA (LPA), in moderate PA (MPA), and in vigorous PA (VPA). PA did not differ between weekdays and the weekend at baseline. Twenty-four-hour sleep time, however, was significantly longer during weekends compared to weekdays, which was associated with less time spent sedentary. Weight loss was associated with a significant increase in LPA at the expense of sedentary time during the weekend but not during weekdays. Regression analyses further revealed an inverse association between change in VPA during the weekend and body composition at 12-month follow-up. Taken together, these results suggest that weekend PA plays an important role in long-term weight management.
