Prevalence of dyslipidemia in children from 2 to 9 years old

ABSTRACT Objective: Analyze the occurrence of dyslipidaemia and associated factors in children aged 2 to 9 years. Method: 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. Results: 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. Conclusion: 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. RESUMEN Objetivo: Analizar la ocurrencia de dislipidemias y factores asociados en niños de 2 a 9 años. Métodos: Estudio transversal, realizado con 700 niños, en una región del noreste de Brasil. Para comparar medias se utilizó la prueba t de Student; y, para la comparación de medianas, la prueba de Mann-Whitney. Resultados: Se encontró una prevalencia de dislipidemia del 68,4%. De forma aislada, la mayoría presentó un nivel de: colesterol deseable total (386; 55,1%), colesterol de lipoproteínas indeseables (376; 53,7%), lipoproteínas de baja densidad - colesterol deseable (514; 73,4%) y triglicéridos deseables (509; 72,7%). En el modelo multivariado final, solo la variable “edad preescolar” fue significativa (razón de prevalencia = 1,14), lo que indica que estos niños tienen más probabilidades de tener dislipidemia que los que están en edad escolar. Conclusión: Se encontró asociación entre dislipidemia y edad preescolar. Se indica la necesidad de programas y estrategias para comprender mejor este problema, además de prevenir enfermedades coronarias precoces. RESUMO Objetivo: Analisar a ocorrência de dislipidemias e fatores associados em crianças de 2 a 9 anos. Métodos : Estudo transversal, realizado com 700 crianças, em uma região do Nordeste brasileiro. Para comparação de médias, utilizou-se o teste t de Student; e, para a comparação de medianas, o teste de Mann-Whitney. Resultados: Encontrou-se uma prevalência de dislipidemia de 68,4%. Is
