Longitudinal Assessment of Intra-abdominal Fat in Postmenopausal Women

: Longitudinal changes in intra‐abdominal (IA) fat and total body fat were assessed in three healthy postmenopausal Caucasian women receiving hormone replacement therapy (HRT) during a seven‐year follow‐up study. Measurements were made using dual‐energy X‐ray absorptiometry, anthropometry, and magnetic resonance images. Changes in intra‐abdominal fat were examined in relation to different patterns of weight modification. The weight‐stable woman had the lowest percent body fat and IA fat at all examinations, with a slight decrease in IA fat at follow‐up. The person with a gradual gain in weight of 1.9 kg experienced small increases in body fat and IA fat. The weight‐cycling woman had the highest weight, percent body fat, and IA fat area at all examinations. The amounts of IA fat and percent body fat fluctuated with body weight fluctuations. Together with other findings, our results suggest that lean, weight‐stable individuals receiving HRT can maintain a low level of IA fat, whereas those experiencing weight gains or regaining lost weight have increases in IA fat.
