OBJECTIVE Excessive central fat puts one at greater risk of disease. In animal studies, stress-induced cortisol secretion has been shown to increase central fat. The objective of this study was to assess whether women with central fat distribution (as indicated by a high waist-to-hip ratio [WHR]), across a range of body mass indexes, display consistently heightened cortisol reactivity to repeat...

OBJECTIVE We examined whether high waist-to-hip ratio (WHR) in women is a biomarker for increased testosterone (T) and higher levels of sexual desire. METHODS Participants were 99 healthy nonobese premenopausal women. Trait levels of mean bioavailable T were estimated from three saliva samples collected at 8:00 am, 9:30 am, and 6:00 pm to 9:00 pm, controlling for phase of the menstrual cycle....

BACKGROUND Obesity is a strong risk factor for type 2 diabetes. However, few studies have compared the predictive power of overall obesity with that of central obesity. The cutoffs for waist circumference (WC) and waist-to-hip ratio (WHR) as measures of abdominal adiposity remain controversial. OBJECTIVE The objective was to compare body mass index (BMI), WC, and WHR in predicting type 2 diab...

• The thermal management strategies of PEMFC are reviewed. waste heat recovery pathways presented. challenges and prospects the aforementioned areas discussed. Despite that Proton Exchange Membrane Fuel Cell (PEMFC) is considered to be an efficient power device; around half energy produced from electrochemical reaction dissipated as due irreversibility cathodic reaction, Ohmic resistance, mass ...

OBJECTIVE To verify the correlation between anthropometric indicators of abdominal obesity and serum lipids in the elderly. METHODS Cross-sectional, descriptive, and analytical study conducted with elderly individuals of both genders enrolled in the Family Health Strategy Program of Campina Grande, PB, Brazil. Abdominal obesity was assessed by waist circumference (WC), abdominal circumference...

The ratio between the body circumference at the waist and the hips (or WHR) is a secondary sexual trait that is unique to humans and is well known to influence men's mate preferences. Because a woman's WHR also provides information about her age, health and fertility, men's preference concerning this physical feature may possibly be a cognitive adaptation selected in the human lineage. However,...

Low adiposity has been linked to elevated mortality from several causes including respiratory disease. However, this could arise from confounding or reverse causality. We explore the association between two measures of adiposity (BMI and WHR) with COPD in the British Women's Heart and Health Study including a detailed assessment of the potential for confounding and reverse causality for each ad...

BACKGROUND Central adiposity as an indicator of visceral fat is linked to vascular and metabolic factors that in turn are related to cognitive decline and dementia. OBJECTIVE To determine whether larger waist-hip ratio (WHR) is associated with structural brain changes that underlie cognitive decline and dementia. DESIGN Cross-sectional analysis of an epidemiologic cohort study of cognitive ...
