fat distributionThe location of fat on the body. There are two patterns of body fat distribution, as measured by the ratio of the corporal diameter at the hips and waist, waist:hip ratio (normal: 0.7–0.8); these patterns differ significantly in co-morbidity of obesity.
Fat distribution, female/male
• Gynecoid pattern (Female pattern)—Fat is deposited in the lower body (abdomen, buttocks, hips, thighs) by mesenchymal differentiation or hyperplasia.
• Android pattern (Male pattern)—Fat is deposited in the upper body, especially around the abdomen. Adipocytes are more sensitive to insulin and catecholamines; fat accumulates by hypertrophy, possibly a function of membrane receptor density. The android pattern has greater lipolytic and lipogenic potential, and thus carries a greater risk for hypertension, cardiovascular disease, diabetes and hyperinsulinaemia.
