Perfíl lipídico en recién nacidos con retardo del crecimiento intrauterino / Serum lipids in newborns with intrauterine growth retardation

Background: The X syndrome, related to coronary disease in adults, could be possibly programmed priory to delivery, in children with intrauterine growth retardation. Aim: To measure serum lipids in newborns with symmetrical or asymmetrical intrauterine growth retardation. Patients and methods: One hundred thirty five newborns with intrauterine growth retardation and 116 normal term newborns, with 38 to 41 gestational weeks, were studied. Total, HDL, and LDL cholesterol, triglycerides and apoproteins. A1 and B were measured in imbilical cord blood samples. Results: No differences in total, HDL, LDL cholesterol, apoproteins A1 and B were observed between the study groups. Triglycerides were higher in newborns with intrauterine growth retardation, compared to normal term newborns (45 ñ 27 and 36 ñ 19 mg/dl respectively, p<0,001). Differences in serum triglyceride levels respect to controls were observed in both male and female newborns with asymmetrical growth retardation. Likewise the differences respect to controls were observed in newborns with mild or severe but not with moderate growth retardation. Conclusions: Newborns with intrauterine growth retardation have higher triglyceride levels than normal term newborns

Perfil lipídico y prevalencia de dislipidemias en niños y adolescentes de Concepción, Chile / Lipid profile and reduce serum lipid levels prevalence in children and adolescents at Concepción, Chile

Serum total, HDL cholesterol and triglycerides were measured in 1,286 males and 816 females from 5 to 18 years old in the city of Concepción. Mean total cholesterol levels were 159ñ30 and 162ñ31 mg/g in males and females respectively. The figures for HDL cholesterol were 46ñ11 and 47ñ11 mg/dl, for LDL cholesterol were 94ñ27 and 96ñ29 mg/dl and for triglycerides were 80ñ35 and 87ñ38 mg/dl. Nine percent of males and 12 percent of females had a total cholesterol over 200 mg/dl. Likewise 10 percent of males and 11 percent of females had a LDL cholesterol over 130 mg/dl. These numbers will help to plan and perform interventions in children in order to prevent cardiovascular diseases
