Elevated FFA concentrations have been shown to reproduce some of the metabolic abnormalities of obesity. It has been hypothesized that visceral adipose tissue lipolysis releases excess FFAs into the portal vein, exposing the liver to higher FFA concentrations. We used isotope dilution/hepatic vein catheterization techniques to examine whether intra-abdominal fat contributes a greater portion of...

OBJECTIVES To analyse the association between body mass index (BMI) and sexual activity, sexual satisfaction, unintended pregnancies, and abortions in obese people and to discuss the implications for public health practices, taking into account the respondents' and their partners' BMI. DESIGN Random probability survey of sexual behaviours. SETTING National population based survey of 12 364 ...

Obesity is an epidemic in American society with approximately one in three adults in the United States being considered obese (1). This compares to ‘‘only’’ one in six adults being considered obese 20 years ago (Fig. 1; ref. 1). The exact reasons for this dramatic increase in obesity prevalence in the last 20 years likely include alterations in diet and amount of physical activity. Obesity is a...

This study aimed to determine if lower serum total prostate-specific antigen (PSA) levels in obese Korean men affect prostate cancer (PCa) screening, as an increased body mass index (BMI) is inversely associated with the PSA level. Between March 2007 and December 2012, 22 208 native Korean men who were eligible to receive a serum PSA test were recruited. Logistic regression was used to estimate...

We have previously shown that sex and obesity independently affect basal very low density lipoprotein (VLDL)-triglyceride (TG) kinetics. In the present study, we investigated the effect of hyperglycemia-hyperinsulinemia on VLDL-TG kinetics in lean and obese men and women (n = 6 in each group). VLDL-TG kinetics were measured during basal, postabsorptive conditions and during glucose infusion (5....

BACKGROUND We investigated whether there were gender differences in the effect of obesity on bone mineral density (BMD) based on menopausal status. METHODS We assessed 5,892 consecutive patients 20 to 91 years old who were referred for dual-energy X-ray absorptiometry (DXA) scans. All subjects underwent a standard BMD scan of the hip (total hip and femoral neck) and lumbar spine (L1 to L4) us...

Obstructive sleep apnea syndrome (OSAS) increases the risk of cardiovascular events. Sympathetic nervous system and hypothalamic-pituitary-adrenal (HPA) axis activation may be the mechanism of this relationship. The aim of this study was to evaluate HPA axis and ambulatory blood pressure monitoring in obese men with and without OSAS and to determine whether nasal continuous positive airway pres...

PURPOSE To assess the impact of body mass index (BMI) on postoperative recovery curve of urinary and sexual function after robotic-assisted laparoscopic prostatectomy (RALP). We hypothesized that overweight and obese men have different recovery curves than normal weight men. MATERIALS AND METHODS We reviewed preoperative and postoperative surveys from 691 men who underwent RALP from 2004-2014...
