An android fat distribution becomes more common post-menopause, where oestrogen is at its lowest levels. Computed tomography studies show that older adults have a two-fold increase in visceral fat compared to young adults. These changes in android fat distribution in older adults occurs in the absence of any clinical diseases.

Obese women with the metabolic syndrome actually had a lower proportion of body fat than obese women without metabolic syndrome. Regional fat distribution, particularly visceral abdominal AT and intermuscular AT, clearly discriminated those with the metabolic syndrome, particularly among the nonobese.

This implies that older men and women can have normal body weight, and even have relatively lower total body fat, but still have metabolic syndrome, due to the amount of AT located intra-abdominally or interspersed within the musculature.

What makes this observation more remarkable is that these associations were much less robust or even nonexistent for subcutaneous AT. More subcutaneous AT in the thighs of obese men and women was actually associated with a lower prevalence of metabolic syndrome.

This is consistent with previous reports demonstrating that total leg fat mass, most of which was subcutaneous AT, is inversely related to cardiovascular disease risk. Albu et al 18 suggested that similar levels of visceral AT in blacks and whites may confer different metabolic risk.

Our data support the contention by some that BMI may not accurately reflect the degree of adiposity in certain populations. The current results parallel our previous observation in the Health ABC cohort that visceral and intermuscular AT strongly predict insulin resistance and type 2 diabetes.

These associations between regional fat deposition and metabolic dysregulation are also consistent with other previous findings in both middle-aged and older adults.

Although we included in the analysis physical activity as a potential confounder to our associations, it is possible that the self-reported estimates for physical activity were not sensitive enough to detect significant associations with metabolic syndrome demonstrated in previous studies.

However, predictors of the incidence of metabolic syndrome can be examined when data become available in this longitudinal study. There are several possible explanations for the observed association between excess visceral fat accumulation and the metabolic syndrome.

Visceral fat is thought to release fatty acids into the portal circulation, where they may cause insulin resistance in the liver and subsequently in muscle. A parallel hypothesis is that adipose tissue is an endocrine organ that secretes a variety of endocrine hormones such as leptin, interleukin 6, angiotensin II, adiponectin, and resistin, which may have potent effects on the metabolism of peripheral tissues.

In conclusion, excess accumulation of either visceral abdominal or muscle AT is associated with a higher prevalence of metabolic syndrome in older adults, particularly in those who are of normal body weight.

This suggests that practitioners should not discount the risk of metabolic syndrome in their older patients entirely on the basis of body weight or BMI. Indeed, generalized body composition, in terms of both BMI and the proportion of body fat, does not clearly distinguish older subjects with the metabolic syndrome.

Moreover, racial differences in the various components of the metabolic syndrome provide strong evidence that the cause of the syndrome likely varies in blacks and whites.

Thus, the development of a treatment for the metabolic syndrome as a unifying disorder is likely to be complex. Correspondence: Bret H.

Subcutaneous fat distribution composition measurements Subcutaneous fat distribution help determine health risks Subchtaneous assist gat creating an exercise and nutrition plan to maintain a healthy weight. Subcuyaneous, the presence of unwanted body fat is not the only concern associated with an unhealthy weight. Where the fat is stored, or fat distribution, also affects overall health risks. Surface fat, located just below the skin, is called subcutaneous fat. Unlike subcutaneous fat, visceral fat is more often associated with abdominal fat. Subcutaneous fat distribution
