Objective: To investigate the appropriate cut-off values of waist circumference(WC)for central obesity and severe central obesity in Chinese adults.
Methods: A total of 10 265 participants aged 35-69 years from the cross-sectional survey of the PRC-USA Collaborative Study of Cardiovascular and Cardiopulmonary Epidemiology between 1993 and 1994 with integral data were included. Each integer unit in centimeters of WC in a given range was used as the cut-off point to detect clustering of risk factors, which was defined as an individual with 2 or more risk factors including hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia and low levels of high-density lipoprotein cholesterol. Sensitivity, specificity and distance from the receiver operating characteristic (ROC) curves to the upper left corner of the ROC graph were calculated. The WC value corresponding to the point on the ROC curve nearest to the upper left corner was considered as the optimal cut-off value for central obesity and the value corresponding to the point with specificity of 90% or more was considered as the optimal cut-off for severe central obesity.
Results: The mean WC was (80.5 ± 9.9) cm in men and (77.8 ± 10.0) cm in women; 18.1% (890/4 921) of men and 14.5% (776/5 344) of women were identified with two or more major risk factors. Based on the ROC curve analysis, the optimal value of WC to detect clustering of risk factors was ≥ 84 cm for men and ≥ 80 cm for women, and the shortest distance to the upper left corner was 0.430 and 0.450, respectively. The cut-off values of WC to detect clustering of risk factors with specificity of 90% or more were ≥ 93 cm and ≥ 91 cm for men and women, respectively.
Conclusion: The cut-off points of WC for central obesity and severe central obesity in Chinese adults obtained from this study are equal or similar to the WC cut-off values proposed by the Guidelines for Prevention and Control of Overweight and Obesity in Chinese Adults.

Background: An association exists between obesity and reduced testosterone levels in males. The propose of this research is to reveal the correlation between 15 indices linked to obesity and lipid levels with the concentration of serum testosterone, and incidence of testosterone deficiency (TD) among adult American men.
Methods: The study utilized information gathered from the National Health and Nutrition Examination Survey (NHANES) carried out from 2011 to 2016.

Background: Menopause is a significant phase in women's health, in which the incidence of obstructive sleep apnea (OSA) is significantly increased. Body fat distribution changes with age and hormone levels in postmenopausal women, but the extent to which changes in body fat distribution affect the occurrence of OSA is unclear.
Methods: This research performed a cross-sectional analysis utilizing data from the 2015-2016 National Health and Nutrition Examination Survey (NHANES).

Background: Obesity is a risk factor for heart failure (HF) development but is associated with a lower incidence of mortality in HF patients. This obesity paradox may be confounded by unrecognized comorbidities, including cachexia.
Methods: A retrospective assessment was conducted using data from a prospectively recruiting multicenter registry, which included consecutive acute heart failure patients.

Background: Individuals with metabolic syndrome (MetS) are at a higher risk of developing depressive symptoms, with inflammation hypothesized to mediate this association. This study used data from the National Health and Nutrition Examination Survey (NHANES) (2015-2020) to investigate the relationship between MetS and depression and assess the mediating role of inflammatory markers.
Methods: This cross-sectional study included 20,520 participants.

Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and the posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude in response to negative and unexpected outcomes, whereas the P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al.
