STUDIES IN HYPERTRIGLYCERIDEMIA .4. DIETARY-INTAKE, ADIPOSE-TISSUE DISTRIBUTION AND COMPOSITION IN RANDOMLY SELECTED HYPERTRIGLYCERIDAEMIC AND NORMOTRIGLYCERIDAEMIC MIDDLE-AGED SWEDISH MEN

Hypertriglyceridaemia is often accompanied by abdominal obesity. Dieta ry modification including energy restriction and fat modification ofte n improves the hypertriglyceridaemic state. The aims of this study wer e to assess the customary dietary composition as well as the degree of abdominal obesity in newly discovered randomly selected hypertriglyce ridaemia. The hypertriglyceridaemic group (n=65) was matched by age, 4 0-50 yrs, and sex, male, to the likewise randomly selected normotrigly ceridaemic one (n=61). The daily energy intake or the composition of t he diet, evaluated by a combination of dietary history and 5-day regis tration of menu, did not differ between the two groups. The fatty acid composition of the abdominal subcutaneous adipose tissue reflecting t he quality of the dietary fat during the preceding years was not diffe rent between the hyper- and normotriglyceridaemic group. The degree of abdominal obesity, assessed by computerized tomography, was significa ntly higher in the hyper- than in the normotriglyceridaemic group. In a logistic regression analysis, abdominal obesity did not remain as an independent variable related to hypertriglyceridaemia. In conclusion, the results of this study suggest that in the majority of triglycerid aemic males neither dietary habits nor abdominal obesity do explain th eir hypertriglyceridaemia.
