SEKI, Mario et al. Evaluation of lipids and lipoproteins range values for children and adolescents: associations of dyslipidemia to overweight in schoolchildren from 4 to 19 years old from Maracaí (State of São Paulo). J. Bras. Patol. Med. Lab. [online]. 2006, vol.42, n.4, pp. 265-270. ISSN 1676-2444. http://dx.doi.org/10.1590/S1676-24442006000400007.
OBJECTIVE: To evaluate the lipids and lipoproteins range values established for children and adolescents from Maracaí, State of São Paulo, through the associations of dyslipidemia and overweight in students from four to 19 years old, from that city. METHODS: The lipid profiles and anthropometric indexes were determined for 2,481 students of both sexes, separated into two age ranges from four to nine (n = 1,121) and ten to 19 (n = 1,360). The cut-points to rank the dyslipidemia have been set up in previous works on range values for lipids and lipoproteins for children and adolescents from Maracaí, State of São Paulo. RESULTS: In the four to nine years old, the associations of triglycerides > 130mg/dl (for both sexes) and of LDL-cholesterol > 101.1 mg/dl (male) to overweight were statistically significant. Among the students from ten to 19 years old, the associations of triglyceride > 131mg/dl (both sexes), of total cholesterol > 161.3mg/dl (male) and LDL-cholesterol > 93mg/dl (male) were statistically significant. The cut-points established by percentile 5 of HDL-cholesterol for both sexes and age group did not show significant associations to overweight. CONCLUSION: The achieved results supply evidence for studies on the range values for lipids and lipoproteins for children and adolescents, and allow for broadening the discussions on the values for reasonable cut-points that could define dyslipidemia within the Brazilian population of children and youngsters.
