AI Article Synopsis
- * Results reveal that while higher BMI is linked to better muscle mass and strength, higher VFA is associated with worse outcomes and metabolic risks related to sarcopenia.
- * The findings suggest that both BMI and VFA should be taken into account for a more accurate assessment of sarcopenia risk and prevention strategies in older individuals.
Article Abstract
The association between obesity and sarcopenia remains controversial. The present study was conducted to explore the associations among body mass index (BMI), visceral fat area (VFA), and sarcopenia in older people and analyze their potential mechanisms. This cross-sectional study included 861 community-dwelling older Chinese people from three regions of China. BMI, VFA, muscle mass, muscle strength, physical performance, body composition, and metabolic markers were measured. Muscle mass and muscle strength were positively correlated with BMI, but were negatively correlated with VFA. Simple overweight/obesity was negatively associated with sarcopenia (OR = 0.07, 95% CI = 0.03~0.18), and the OR value was lower than combined obesity (OR = 0.16, 95% CI = 0.09~0.28). Fat free mass and total body protein were positively associated with high BMI but negatively associated with high VFA. Furthermore, high VFA was adversely associated with some metabolic risk factors of sarcopenia. Combination of BMI and VFA increased diagnostic efficiency of low muscle mass and sarcopenia. In conclusion, high BMI was negatively associated with sarcopenia, while high VFA attenuated the negative association between high BMI and sarcopenia. The opposite association may partially be attributed to their different associations with body composition and metabolic risk factors of sarcopenia. Therefore, bedsides BMI, VFA and its interaction with BMI should be considered in sarcopenia prevention.

Aims: To compare the effects of ipragliflozin, a sodium-dependent glucose transporter-2 inhibitor, and those of metformin on the visceral fat area (VFA), a prospective, multi-centre, open-label, blinded-endpoint, randomized, controlled study was undertaken. The generated data were used to examine the effects of ipragliflozin and metformin on indices of hepatic steatosis and liver fibrosis.
Materials And Methods: In total, 103 Japanese patients with type-2 diabetes (T2D), body mass index (BMI) of ≥22 kg/m and glycated haemoglobin level of 7%-10% were randomly administered ipragliflozin 50 mg or metformin 1000 mg for 24 weeks.

Subdivision of Endocrinology and Metabolism, Health Screening and Promotion Center, Asan Medical Center, Seoul, Republic of Korea. Electronic address:
Background: Changes in body composition, including loss of muscle mass and obesity, adversely affect lung function.
Research Question: What is the relationship between lung function, visceral adiposity, and skeletal muscle mass, considering myosteatosis measured using computed tomography (CT) scans in middle-aged Korean adults?
Study Design And Methods: We reviewed 15,827 participants (9237 men and 6590 women), with a mean age of 52.5 ± 8.
Background: Recent research has focused on the prognostic relevance of preoperative sarcopenia and sarcopenic obesity in various cancers. In this study we investigated the relationship between visceral fat area (VFA), psoas muscle area (PMA), and the prognosis of patients undergoing colorectal cancer surgery.
Methods: Patients with stage III colorectal cancer who underwent surgery between July 2013 and April 2020 were included.
Obesity modifies the association between abnormal glucose metabolism and atrial fibrillation in older adults: a community-based longitudinal and prospective cohort study.

Department of Cardiology, The Second Affiliated Hospital of Harbin Medical University, Harbin, Heilongjiang 150001, China. Electronic address:
Objective: To investigate the modifying role of obesity in the association between abnormal glucose metabolism and atrial fibrillation (AF) risk in older individuals.
Methods: From April 2007 to November 2011, 11,663 participants aged ≥60 years were enrolled in the Shandong area. Glucose metabolic status was determined using fasting plasma glucose and hemoglobin A1c levels, and obesity was determined using body mass index (BMI), waist-to-hip ratio (WHR), and visceral fat area (VFA).
Characteristics of lipid metabolism and fat distribution in patients with primary hyperparathyroidism and their Mendelian randomization study.
Endocrine

Article Synopsis
- The study investigates the relationship between primary hyperparathyroidism (PHPT) and lipid metabolism, analyzing clinical data and fat distribution in 157 PHPT patients compared to matched controls.
- Previous research hints at a link between parathyroid hormone (PTH) levels and lipid profiles, yet this study finds no significant differences in lipid-related measurements or fat distribution between PHPT patients and controls.
- Overall, the analysis suggests that PTH levels do not have a significant impact on lipid metabolism indicators, as various correlations remained non-significant even after accounting for factors like calcium levels and vitamin D.
