Hairston KG, Scherzinger A, Foy C, Hanley AJ, McCorkle O, Haffner S, Norris JM, Bryer-Ash M, Wagenknecht LE - Diabetes Care (2009)

Bottom Line: RESULTS Mean 5-year increases in VAT areas in women were 18, 7, 4, 0.4, and -3 cm(2) for African Americans and 13, 7, 3, 1, and -15 cm(2) for Hispanics, across the 5 age decades (trend not significant).Mean 5-year increases in SAT areas in women were 88, 46, 19, 17, and 14 cm(2) for African Americans and 53, 20, 17, 12, and 1 cm(2) for Hispanics, across the 5 age decades (P < 0.05 for both).Similar trends have been observed in men.

ABSTRACT
OBJECTIVE To describe the 5-year change in visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) areas. RESEARCH DESIGN AND METHODS Absolute change in VAT and SAT measured by abdominal computed tomography scans has been obtained at a 5-year interval from African Americans (n = 389) and Hispanic Americans (n = 844), aged 20-69 years, in 10-year age-groups. RESULTS Mean 5-year increases in VAT areas in women were 18, 7, 4, 0.4, and -3 cm(2) for African Americans and 13, 7, 3, 1, and -15 cm(2) for Hispanics, across the 5 age decades (trend not significant). Mean 5-year increases in SAT areas in women were 88, 46, 19, 17, and 14 cm(2) for African Americans and 53, 20, 17, 12, and 1 cm(2) for Hispanics, across the 5 age decades (P < 0.05 for both). Similar trends have been observed in men. CONCLUSIONS Accumulation of abdominal fat is greatest in young adulthood. These data may be useful in identifying subgroups at risk of type 2 diabetes.

Figure 1: Five-year change in VAT (A) and SAT (B) by baseline age categorized into ethnic groups. ■, 20–29 years; ▤, 30–39 years; □, 40–49 years; , 50–59 years; ▩, 60–69 years.

Mentions: The youngest group presented with the lowest baseline VAT area, with African Americans having smaller VAT areas across all age-groups compared with Hispanics (supplementary Tables A1–A4, available in an online appendix at http://care.diabetesjournals.org/cgi/content/full/dc09-0336/DC1). The rate of increase in VAT area slowed with advancing age-group (Fig. 1 A). The absolute changes from baseline were 18, 7, 4, 0.4, and −3 cm2 for African American women; 12, 0.1, 3, −3, and −8 cm2 for Hispanic women; 13, 7, 3, 0.7, and −15 cm2 for African American men; and 7, 5, 6, 12, and 2 cm2 for Hispanic men. All trends except for the Hispanic men showed declines in fat accumulation over the age-groups; however, none of the trends were significant.
