Dislipidemia em escolares de 10 a 14 anos da cidade do Recife/PE â 2007




Dyslipidemia is a clinical condition characterized by abnormal concentrations of lipids or lipoproteins in the blood and is determined by genetic and environmental factors. Its occurrence is on the rise among the young population. Abnormal lipid levels are related to a greater incidence of hypertension and atherosclerosis. The objectives of dissertation were to assess the magnitude of dyslipidemias; determine the lipid profile according to gender and nutritional status classification parameters; and investigate associations between dyslipidemias and excess weight, abdominal obesity and a family history of cardiovascular diseases among schoolchildren from Recife/PE. A cross-sectional study was carried out with 470 male and female adolescents between 10 and 14 years of age in the public school system. Blood samples were taken for the lipid profile and information was collected on personal data, socioeconomic situation, nutritional status (weight, height, waist circumference and waist circumference/height ratio) and family history of the participants. Statistical analysis was carried out using the Epi-info 6.04 and SPSS 13.0 programs, with significance set at 5%. The findings gave rise to two original articles. The results of the first revealed that the majority of the population had dyslipidemia (63,8%, IC95% 59,3-68,2), the most prevalent form of which was hypoalphalipoproteinemia (56%, IC95% 51,3-60,5). The adolescents with excess weight or abdominal obesity had higher levels of triglycerides and lower levels of HDL cholesterol (p <0.05). The results of the second article revealed that hypertriglyceridemia was the only form of dyslipidemia associated to a family history of early cardiovascular disease (p = 0.034); that abnormal LDL-c and HDL-c values were associated to excess weight (p = 0.022; p = 0.004) and abdominal obesity (p <0.05); and the central fat distribution (classified by the waist circumference/height index) was the greatest risk factor for LDL-c abnormalities (RP 5.47; IC 1.58 â 18.52). A high percentage of dyslipidemia was found among the adolescents analyzed, which alerts to the need for the determination of the lipid profile in this age group. Excess weight and abdominal obesity proved risk factors for abnormal LDL-c and HDL-c values. The findings demonstrate the need for the prevention and/or control measures regarding adiposity as a way to reduce possible lipid abnormalities
