[The Fuenlabrada study: smoking habits in children and adolescents. Effect on various cardiovascular risk factors]. / Estudio de Fuenlabrada: hábito tabáquico en niños y adolescentes. Influencia sobre las variables de riesgo cardiovascular.

We studied 1,274 healthy children of both sexes from 10 until 18 years of age, in Fuenlabrada, Madrid. We knew the tobacco consumption by means of direct asking to the children, without the presence of their parents. We studied the smoking habit of their parents by means of inquiries. The percentage of smoker children was 30% (24% of them had smoker parents, and 6% did not). We studied the tobacco influence in several parameters of cardiovascular risk; it was found that C-HDL levels in the smoker children were 5 mg/dl lower than the non-smokers, and the ratio C-LDL/C-HDL in the smokers was 1,2 times greater than in the non-smokers.

[The Fuenlabrada study: normal values of arterial pressure in children and adolescents]. / Estudio de Fuenlabrada: valores normales de la tensión arterial en niños y adolescentes.

We have studied 1,939 healthy children of both sexes (1.003 boys and 936 girls), aged from 4 to 18 years, of the city of Fuenlabrada (Madrid). The following parameters were determined: blood pressure, weight, height, triccipital folds, the rohrer index, total cholesterol, triglycerides, lipoproteins, blood sugar and uric acid. The results of the blood pressure have been expressed by means of percentiles in relation with age, weight, and height. The correlation coefficients have been statistically significant for the height, weight, age, triccipital skinfolds, triglycerides and C-VLDL. We have relationed our results with other national and international studies.

[The Fuenlabrada study: lipids and lipoproteins in children and adolescents]. / Estudio de Fuenlabrada: lípidos y lipoproteínas en niños y adolescentes.

We studied in 2,153 children of both sexes from birth until 18 years of age, in Fuenlabrada, Madrid, the following parameters: the height, weight, tricipital and subscapular skinfolds, blood pressure, lipids, lipoproteins, glycemia, uric acid and smoking habits. We obtained the next mean values: Total cholesterol (TC), 166 +/- 36 mg/dl; triglycerides, 63 +/- 39 mg/dl; HDL-C, 53 +/- 13 mg/dl; LDL-C, 102 +/- 34 mg/dl; VLDL-C, 13 +/- 6 mg/dl. TC, HDL-C and LDL-C levels did not present any significant differences with respect to sex until 12 years of age. But they were significantly higher in girls than in boys in adolescence. In contrast, TG and VLDL-C levels were higher in girls than in boys until 12 years of age, they did not present any difference in adolescence. The significant change of the lipoproteinic pattern in adolescence is connected with the hormonal distribution that is produced in puberty.

[Prevalence of breast feeding and its relation to cardiovascular risk factors in the pediatric population of Fuenlabrada]. / Prevalencia de la lactancia materna y su relación con los factores de reisgo cardiovascular en la población pediátrica de Fuenlabrada.

The infant nutrition is surveyed on 1893 children of both sexes, aged from 0 to 18 years, in Fuenlabrada, Madrid. The percent of children with breast feeding has strongly decreased (47%) during the period 1965-1983, so its endurance has shortened (15%). The kind of feeding is related to the age mother and her smoking habit. The statistical correlation between the newborn intake and the cardiovascular risk factors is studied; no significant differences are found, excepting a temporary increase of the total cholesterol during the first quarter of life.
