Your waistline not only makes or breaks your esthetic appearance; if you belly gets too large, it may greatly jeopardize your health and even longevity.
Waist circumference strongly correlates with abdominal obesity and is the most commonly used measure of body fat distribution.[1, 2] Many studies have found enlarged waist circumferences to be associated with all-cause mortality, in most cases independently of general obesity.[3-11]
Abdominal obesity (aka visceral obesity) appears to be more strongly associated with multiple chronic diseases than is gluteo-femoral obesity (fat deposition around the butt and thighs). Increased waist circumference confers a health risk even in normal weight people.
A notable large study investigated the association of waist circumference with mortality using intuitive 2 in (5 cm) increments for men and women, and also evaluated risk within narrow categories of body fatness (BMI). In addition, the study estimated years of life lost due to a large waist circumference.
Reduced levels of anabolic hormones can contribute to aging and frailty. Most studies that have investigated this focused on the relationship between individual hormones and specific age-associated diseases. An interesting study in older women aged 70-79 years sought to examine the associations of individual anabolic hormonal deficiencies of free testosterone, IGF-1 and DHEA, and to assess their combined effects as well.
