Sažetak
In 1969, our Institute started a longitudinal study on the prevalence of chronic diseases in Croatia. The sample comprised urban and rural population from two continental and three coastal areas, with follow-ups in 1972 and 1982. The results showed marked regional differences in general and cardiovascular mortality. Mortality was the lowest in the coastal region (Island of Vis) and the highest in the northern, continental region (Virovitica - town and surroundings). Trace element deficiency is considered to be a risk factor for cardiovascular disorders. Therefore, during the fourth follow-up in 2006, serum concentrations of selenium (SSe), copper (SCu), and zinc (SZn) were additionally measured in 37 elderly subjects from Vis (20 women and 16 men, aged 72– 87) and 63 subjects from Virovitica (38 women and 25 men, aged 71– 88). The study was performed in accordance with the ethical principles of the Helsinki Declaration and approved by the Institute’ s Ethical Committee. Trace element concentrations were determined using electrothermal (SSe) or flame AAS (SZn and SCu). Accuracy was checked using reference material (BCR no. 637-639) and through regular participation in the UK TEQAS programme. The results showed a significantly lower SSe (p=0.000) in subjects from Virovitica, whose general health condition and perceived physical fitness wasworse than in the subjects from Vis. There were no significant differences between the groups in SZn, SCu, age, BMI, or alcohol intake. However, there was a significant difference (p<0.02) in the type of alcohol consumed: subjects from Virovitica drank less wine, but more beer and spirits. Furthermore, they reported significantly lower consumption of fish and olive oil and higher consumption of salt, smoked meat, and coffee. Our results indicate that in addition to several well-known beneficial components of the Mediterranean-style diet, selenium may play a role in the protection from cardiovascular morbidity and mortality.
