Introduction/Aim. Epidemiological investigation of risk factors for acute myocardial infarction (AMI) does not work is to primarily find new risk factors, as they have already identified a few hundred, but to investigate the representation in that area, in order to take appropriate preventive measures that could stop the further growth of diseased and dying from this disease. The aim of this study was to investigate the unhealthy nutrition as risk factor for acute myocardial infarction in examined population. Methods. A casecontrol study with 155 patients with a first myocardial infarction and 155 controls, matched with respect to sex and age (± 2 years) from the city of Niš, was used. Data was obtained throught the epidemiological questionnaire. Results. Number of servings (p=0,009), eating pieces of bread, white bread, consuming the meat and meat products more than 3 times per week (p for trend for all < 0,001), eating fried foods, sweets and higher intake of eggs, as roasted as boiled was significantly higher in patients (p < 0,001). Regular intake of food (p < 0,001), eating dairy products (p < 0,001), fresh fruit (p < 0,001), and fresh vegetables (p < 0,001) is significantly more often in healthy subjects. The use of fat was even in childhood in both groups (72,50% respectively 71,80%), but before disease, it was significantly more often in patients (p < 0,001) as well as the use of oil (p < 0,001). In the univariate model, as the strongest independent risk factor was the irregular nutrition (OR 14,217, p < 0,001), used meat products more than 3 times a week (OR 9,525, p < 0,001) and fried foods (OR 8,868, p < 0,001). As a protective factor, frequent use of fresh vegetables (OR 0,333, p < 0,001) and fresh fruit (OR 0,511, p=0,004). In the multivariate model as the strongest risk factor was the irregular nutrition (OR 47,839, p < 0,001) and the use of the meat more than 3 times per week (OR 38,925, p < 0,001). Conclusion. These findings are very important for further epidemiological research and should improve preventive strategies of this serious disorder in different geografical areas.

unhealthy nutrition; acute myocardial infarction; case-control study

1. Based on the study and statistical analysis confirmed that there was a significant correlation between inadequate diet and the occurrence of acute myocardial infarction in the city of Nis.

2. The larger amount of intake of certain foods is a risk factor, and the greater intake of bread, meat, meat products and eggs, leads to higher risk of AMI.

3. Regular intake of meals, fresh fruit and vegetables are protective factor for the occurrence of acute myocardial infarction.

4. The use of fat and oils represent a risk factor. In childhood, the use of fat is equally in both groups.

5. Add salt in food was not statistically significant in all treated groups.

6. Timely detection of inadequate nutrition as a risk factor and adequate choice and moderate amounts of certain ingredients in the investigated area, can lead to a significant reduction in morbidity and mortality from acute myocardial infarction.
