Objective: To evaluate the association between time spent on sedentary behaviors with anthropome tric variables and the percentage of body fat.
Subjects And Method: 43 schoolchildren (72% male) participated, aged between 6 and 9 years. Anthropometric measurements were weight, height, body mass index, arm circumference, waist circumference, subscapular skinfold, tricipital skinfold, arm muscle circumference, arm area, arm muscle area, arm fat area, and waist-to-height ratio. The percen tage of body fat was measured using an isotopic technique considered the gold standard(deuterium). The average time spent on sedentary behaviors recorded by self-report, during three non-consecutive weekdays were school activity, extracurricular work at home, watching television, using electronic devices screens, and sedentary recreational activities.
Results: 32% of the subjects were eutrophic considering the percentage of body fat. 52% of daily time is spent on sedentary activities with no significant differences between boys and girls, 12.4 h vs 13.37, respectively. Time spent watching television was significantly associated (p < 0,05) with greater values of the anthropo metric variables [weight, body mass index, waist circumference, waist-to-height ratio, skinfold (subs capular and tricipital)], and body fat percentage.
Conclusion: The time spent watching television is associated with an increase in body fat. There is an urge to promote recreational activities that involve an increase in moderate and intense physical activity in schoolchildren.

The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), which is increasingly being recognized as a leading cause of chronic liver pathology globally, is increasing. The pathophysiological underpinnings of its progression, which is currently under active investigation, involve oxidative stress. Human adipose tissue, an integral endocrine organ, secretes an array of adipokines that are modulated by dietary patterns and lifestyle choices.

The maintenance of an appropriate ratio of body fat to muscle mass is essential for the preservation of health and performance, as excessive body fat is associated with an increased risk of various diseases. Accurate body composition assessment requires precise segmentation of structures. In this study we developed a novel automatic machine learning approach for volumetric segmentation and quantitative assessment of MRI volumes and investigated the efficacy of using a machine learning algorithm to assess muscle, subcutaneous adipose tissue (SAT), and bone volume of the thigh before and after a strength training.

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Mitochondrial rRNAs play important roles in regulating mtDNA-encoded gene expression and energy metabolism subsequently. However, the proteins that regulate mitochondrial 16S rRNA processing remain poorly understood. Herein, we generated adipose-specific Wbscr16-/-mice and cells, both of which exhibited dramatic mitochondrial changes.

White adipose tissue (WAT) comprises a plethora of cell types beyond adipocytes forming a regulatory network that ensures systemic energy homeostasis. Intertissue communication is facilitated by metabolites and signaling molecules that are spread by vasculature and nerves. Previous works indicated that WAT responds to environmental cues by adapting the abundance of these "communication routes", however, high intra-tissue heterogeneity questions the informative value of bulk or single cell analyses and underscores the necessity of whole-mount imaging.
