Abstract
Analyze the occurrence of dyslipidaemia and associated factors in children aged 2 to 9 years. Cross-sectional study, carried out with 700 children, in a region of Northeast Brazil. For comparison of means, Student's t test was used; and, for the comparison of medians, the Mann-Whitney test. A prevalence of dyslipidaemia of 68.4% was found. In isolation, the majority had a level of: total desirable cholesterol (386; 55.1%), undesirable lipoprotein cholesterol (376; 53.7%), low density lipoproteins - desirable cholesterol (514; 73.4%) and desirable triglyceride (509; 72.7%). In the final multivariate model, only the variable "preschool age" was significant (prevalence ratio = 1.14), indicating that these children are more likely to have dyslipidaemia than those of school age. An association was found between dyslipidaemia and preschool age. The need for programs and strategies to better understand this problem is indicated, in addition to preventing early coronary diseases.
Highlights
Dyslipidaemia consists of changes in the lipid profile, expressed by elevated levels of total cholesterol (TC), triglycerides (TG) and low-density lipoprotein (LDL-c) as well as low levels of high density lipoprotein (HDL-c)
Population Brazilian studies show, according to region and criterion, prevalence of 10% to 23.5% of dyslipidaemia in children and adolescents. This suggests that childhood should be increasingly considered a concern, as it is a strategic phase in the prevention of atherosclerosis at the population level, considering that life habits are formed in this phase[5]
In Brazil, regional studies point to high prevalence of childhood dyslipidaemia: increased total cholesterol, 86%(7)
Summary
Dyslipidaemia consists of changes in the lipid profile, expressed by elevated levels of total cholesterol (TC), triglycerides (TG) and low-density lipoprotein (LDL-c) as well as low levels of high density lipoprotein (HDL-c). It may occur either alone or in combinations, or it may be hereditary or acquired[1,2]. Population Brazilian studies show, according to region and criterion, prevalence of 10% to 23.5% of dyslipidaemia in children and adolescents This suggests that childhood should be increasingly considered a concern, as it is a strategic phase in the prevention of atherosclerosis at the population level, considering that life habits (important causes of cardiovascular disease risk modulation - CVD) are formed in this phase[5]. In Brazil, regional studies point to high prevalence of childhood dyslipidaemia: increased total cholesterol, 86%(7)
