[Anthropometric data on newborn infants: comparative study of two ethnic groups].

We have studied the birth weights, obstetrics data and anthropometrical data from 1.157 full-term newborns who were delivered in the Hospital del Insalud-Cruz Roja in Ceuta (Spain). Of these newborns, 489 were of arabic origin and 668 of hispanic origin. Arabic newborns were heavier (3.248 +/- 473 g versus 3.280 +/- 431 g, p < 0.001) and longer (50.2 +/- 1.8 cm versus 49.6 +/- 1.8 cm, p < 0.001) than their hispanic counterparts. These differences were not due to a disproportion in sex or gestational age between the groups. Furthermore, the differences were still present after adjustments were made for maternal age, parity and the mother's smoking habit. Thus, this difference in size at birth between arabic and hispanic newborns could be, at least in part, ethnically related.

[Effect of various levels of alcohol consumption on plasma lipoproteins and apoproteins].

To assess the abnormalities induced by alcohol on plasma lipids and lipoproteins and their possibly involved mechanisms three basis of the daily intake: social drinkers (less than or equal to 20 g/day; n = 10), moderate drinkers (greater than 20 to less than 70 g/day; n = 11), and severe drinkers (greater than or equal to 70 g/day; n = 15). Eleven nondrinkers were evaluated as control group. Very low density lipoproteins (VLDL), low density lipoproteins (LDL), high density lipoproteins (HDL)-2 and HDL-3 were isolated by preparative sequential isopicnic centrifugation, and their apolipoprotein and lipidic composition were measured. In the group of severe drinkers, a marked tendency of HDL-3 cholesterol to be higher than in the remaining groups was found. There was no correlation between this parameter and hepatic enzymes. The HDL-2 cholesterol of severe drinkers was significantly increased (p less than 0.005). The parallel enrichment in apolipoproteins C of the HDL-2 particle in all groups of alcohol users suggests a transfer phenomenon from VLDL. The apoA/C ratio of HDL-2 might be useful as a marker of alcohol intake.
