[Analysis of nutritional habits in patients with familial combined hyperlipidemia]

Our objective was to analyze dietary habits of patients with the IIb phenotype of familial combined hyperlipidaemia. These patients were instructed on the proper composition of their diet and they thought that they adhered to these recommendations.

The authors examined 41 patients with IIb phenotype of familial combined hyperlipidaemia. Based on their seven-day dietary records their daily intake was calculated and compared with recommended daily allowances as regards energy intake, intake of plant and animal proteins, fats, linoleic acid, carbohydrates, calcium, iron, potassium, fibre, vitamin A, thiamin, pyridoxine, vitamin C, E, cholesterol and NaCl (Progana programme). With the above results the total serum cholesterol, serum triglyceride, HDL and LDL serum cholesterol and nutritional status (body mass index, percentage of body fat and waist hip/ratio) were compared. When the energy intake was acceptable (99% of the recommended allowance), the fat intake was excessive (138%) as well as the intake of animal protein (148%), cholesterol (145%) and NaCl (159% of the recommended allowance), while the intake of plant proteins and fibre and some vitamins was inadequate. A statistically significant relationship was revealed only as regards the linoleic acid intake and total serum cholesterol (inverse relationship at the 95% probability level, r = 0.43), the other investigated relationships were insignificant. The body mass index values (in men and women 26) and the percentage of body fat (22% in men and 34% in women) are above the recommended range.

Dietary errors in the investigated group thus did not pertain, to the quantity of the diet but its composition. From the results ensures that doctors should pay great attention to explaining dietary principles to their patients.
