Dietary patterns and lifestyle in a sample of a Slovak Romany community.

The aim of this paper is to evaluate dietary habits and behavioural factors related to atherosclerosis in Slovak Romany, the large minority, characterized by high cardiovascular morbidity. The study involved 150 Romany volunteers (68 males, mean age 42.1 +/- 13.9 y and 82 females, mean age 40.9 +/- 13.7 y). Dietary data were obtained by a validated food-requency questionnaire and a single 24-hour dietary recall. The nutrient intake and health behaviour of the Romany population is not consistent with current guidelines for atherosclerosis prevention. The mean intake of fat is higher than the recommended dietary allowance (RDA), especially in males (155.3 % of RDA). In females the intake of alpha-linolenic acid is low, in males the cholesterol content of the food exceeds the acceptable value. The mean intake of protein is higher than the recommendation (males 153% of RDA, females 122.2%), with a high proportion of animal protein. In both sexes the mean intake of vitamins is below the RDA. In comparison to the general population the diet of the Romany males contains significantly more animal protein (p < 0.05), less plant protein (p < 0.05) and folate (p < 0.01). In the diet of the Romany females a significantly lower intake of plant protein (p < 0.05) and vitamin E (p < 0.05) was observed, as well as a lower intake of linoleic acid and iron in both sexes. The cumulation of ten selected cardiovascular risk factors showed that particularly the Romany males could be considered as having more atherogenic profile.

Apolipoprotein E polymorphism in relation to plasma lipid levels and other risk factors of atherosclerosis in two ethnic groups from Slovakia.

The influence of apolipoprotein E (ApoE) genotypes on plasma lipid levels and interaction with other environmental factors was determined in two Slovakian population samples; 146 Romany and 351 Slovak individuals. The two samples differ significantly in the distribution of E3/3 genotypes (p<0.014) and E3/2 (p<0.035). Analysis of variance did not reveal any significant effect of the ApoE genotypes on any of the plasma lipid levels in the Romany individuals. In the Slovak sample the variation in plasma low-density lipoprotein cholesterol (LDL-C) levels was significantly associated with the ApoE genotypes (p=0.012). We detected decreased LDL-C concentrations in males with E2 genotype when compared with E3 and E4 carriers (p=0.008). Further, the E2 genotype was found to be associated with high triglycerides levels (p=0.009). The ethnic samples differ significantly in the prevalence of metabolic syndrome and in the case of males of diabetes. Both the Romany and the Slovak males can be considered as having a more atherogenic profile compared with the females.
