Abstract
Background and objectives: In recent decades, the prevalence of non-communicable diseases (NCDs), such as obesity, diabetes and cardiovascular disorders has increased worldwide; the objective here is to describe the situation in southern Mediterranean countries.Results: Data derived from surveys in the region countries showed that in 2002 more than 60% of all deaths in the southern Mediterranean region are attributed to NCDs. Cardiovascular diseases (CVD) caused from about 34.3 to 52% of all deaths, making it the major killer among NCDs. In almost all of the southern Mediterranean countries, CVD risk factors increased with age, affected more women and urban area and were significantly associated with obesity. The Mediterranean dietary pattern, generally recognised, as a healthy diet is still the model for southern Mediterranean population; however, following the rapid process of urbanisation, southern Mediterranean populations have changed their lifestyle and food habits and tend to shift from traditional food habit. Indeed, intake trends illustrate the fall in whole-grain intake with a rise in animal sources and vegetable oils. Dietary energy has been steadily increasing by approximately 1000 kcal per capita per day between 1965 and 2000, exceeding per caput energy requirements. Protein and carbohydrate contribution to the energy intake show only small deviations and fat contribution to the energy intake is low, whereas fibre intake is generally low and that of SFA is high. Also, sedentarity appears to play a critical role in the development of body fat and may be a risk indicator for features of metabolic syndrome.Conclusion: The major goal to prevent CVD should begin by preventing obesity through physical exercise and healthy nutrition. The nutritional prevention policy required should encourage population to adhere to the Mediterranean model.
