Morphometry of subcutaneous fat lobules of the abdomen and its implication in obesity

Aim: The subcutaneous fat in the lower abdomen (LA) is more resistant to resorption as compared to the upper abdomen (UA).Males and females have variability in fat deposition and resorption in the abdominal region.Hence, there could be a difference in morphology of fat cells of these regions.The present study aims to identify the differences in morphology of subcutaneous fat lobules of upper and LA.Methods: Subcutaneous fat samples were collected from upper and LA of 40 cadavers (33 males and 7 females).The shape, the arrangement, and the color of superficial and deep subcutaneous fat lobules were observed.The height and width were recorded for larger fat lobules.Results: There was a difference in the color, shape, size, and arrangement of the fat lobules between the two locations.Height (P = 0.042) and width (P = 0.008) of deep subcutaneous fat of LA were significantly larger than the UA in males while the height of superficial fat (P = 0.016) was significantly larger in LA than the UA in females.Height of the deep fat of UA (P = 0.018) and width of deep fat of the LA (P = 0.020) were significantly larger in females as compared to males.Conclusion: There was a significant difference in the morphology of the superficial and deep subcutaneous fat based on location and gender of the patient.
