Background: Stroke is the cardiovascular disease which causes the greatest number of deaths in Galicia, mortality, particularly in women, being higher than in the rest of Spain. The aim of this study was to investigate the risk factors of stroke and its importance in Galicia., Methods: A hospitalary study of cases and controls was performed including 76 patients with stroke and 76 controls individually paired for age, sex, population habitat and date of admission with anamnesis, weight, height and blood pressure, analysis and electrocardiogram being carried out in all., Results: An association was found between the disease and family history of stroke (odds ratio = 3.6, confidence interval 95% = 1.2-13.3), personal history of stroke (17.9; 4.0-79.1), personal history of atrial fibrillation (15.0; 3.3-68.3), high blood pressure (4.5; 1.9-11.6) and ingestion of alcohol greater than or equal to 80 g/day in comparison with abstemious patients adjusted for the effect of high blood pressure (2.5; 1.1-5.7). An association was also observed with serum cholesterol levels greater than or equal to 250 mg/dl (6.46 mmol/l) (3.3; 1.2-8.8, in comparison with cholesterol less than 200 mg/dl). No association was found with the cigarette smoking (1.2; 0.7-2.3)., Conclusions: The results observed for high blood pressure and the ingestion of alcohol regardless of the same are of importance in primary prevention due to being modifiable risk factors. The association with family history of stroke and auricular fibrillation reinforce the needs for primary prevention measures in these subpopulations while having had a stroke or a transitory ischemic attack is the characteristic with the most risk reinforcing the need for secondary prevention measures which have found to be effective. The controls presented abnormally low cholesterol levels that do not reflect those of the population from which they originate, thus existing the possibility that the association observed is spurious.

Background: The aim of this study was to determine the levels of certain factors of cardiovascular risk in children and adolescents in rural areas of Gallicia., Methods: One thousand eight children between the ages of 6 and 15 years selected from three primary schools were studied. Weight, height, blood pressure, serum levels of cholesterol and self admitted consumption of tobacco were determined in each participant., Results: The patterns of body mass, blood pressure and total cholesterol selected to age and sex are very similar to those observed in a great deal of the Spanish and foreign studies. However, the absolute values do not necessarily coincide. The children studied were more obese than those reported in other studies carried out in the rest of Spain with similar values of systolic blood pressure and lower cholesterol levels. The levels of cholesterol in this study were within the range observed in other Western countries, lower than those found in other parts of Spain but much higher than the ideal quantities recommended by the WHO. Blood pressure was similar to that of a recent meta-analysis of Spanish studies but much higher than that observed in the Second American Task Force Study. With regard to the use of tobacco, this population demonstrated lower prevalences to those of other Spanish populations. From the age of 14 the consumption of cigarettes greatly increases, especially in boys., Conclusions: Obesity and blood pressure appear to be a more important potential problem than cholesterol among the cardiovascular risk factors considered in the children studied in comparison with populations of a similar age. If prevention plans on the use of tobacco are foreseen in Spain, they should be made before the age of 14 when an important number of children already smoke or have tried cigarettes.
