Background: Both intra-abdominal fat (IAF) and HDL cholesterol (HDL-C) are known to be associated with cardiometabolic health problems, with an inverse correlation between them. However, there is little information about the association between HDL-C concentration with future accumulation of IAF. We conducted a prospective study to evaluate whether baseline HDL-C concentration was associated with the accumulation of CT-measured intra-abdominal fat (IAF) over 5 years.

Methods: All participants were Japanese-American men and women between the ages of 34 to 74 years. HDL-C concentration and CT-measurements of IAF, abdominal (SCF) and thigh (TF) subcutaneous fat cross-sectional areas were evaluated at baseline and 5 year follow-up visits. Data were analyzed to determine the association between HDL-C and future 5-year accumulation of IAF.

Results: A total of 545 subjects with and without diabetes (296 men, 249 women, and mean age 53.6±11.4 and 54.0±12.0 years, respectively) were included. The mean (SD) HDL-C concentration was 1.3 mmol/L (0.4) in men and 1.7 mmol/L (0.4) in women and mean (SD) IAF was 102 cm2 (53.8) in men and 74.5 cm2 (46.8) in women. Baseline HDL-C concentration was inversely associated with Δ IAF over 5 years using multivariable regression analysis adjusting for age, sex, diabetes family history, weight change over 5 years, and baseline measurements of BMI, IAF, abdominal SCF, abdominal circumference, TF, and HOMA-IR.

Conclusions: These results demonstrate that HDL-C concentration predicts significantly future accumulation of IAF over 5 years independent of age, sex, insulin sensitivity, and body composition in nondiabetic Japanese-American men and women.
