[The relationships between apoprotein levels and body mass and atherogenic indices and sports activity in Aragonese schoolchildren].
OBJECTIVE
The main purpose of this study was to establish the relationship between the apoproteins normally employed in clinical practice and the Quetelet indexes, atherogenic and physical activity in order to know how these parameters are modified in relationship to life style and hence, be able to modify inadequate habits in order to slow down the atherogenic process.


METHODS
In a group of 82 schoolchildren of both sexes, we assessed the relationships between the levels of apoproteins A-1 and B, and the quotient apoprotein A-1/apoprotein B with the atherogenic indexes and the body mass (Quetelet) in relationship to the practice of sports.


RESULTS
The average values obtained for each parameter studied were within the established normal range, although 4.88% of the boys and 2.7% of the girls showed lower levels of apoprotein A-1 and 9.76% of the boys and 10.8% of the girls showed higher levels of apoprotein B. In addition, 19.25% of the boys and 8.1% of the girls showed a body mass index superior to 2 standard deviations for their age. The correlations found showed statistic value (p < 0.01) with the atherogenic index for both groups, whereas the Quetelet index was only significant (p < 0.05) with the apoprotein B in both groups and for the quotient apoA-1/apoB (p < 0.05) in the case of the boys. Physical activity did not show an important relationship with the rest of the analyzed parameters since only the girls showed statistical value (p < 0.05) with the quotient apo A-1/apo B and with the atherogenic index.


CONCLUSIONS
These data allow us to conclude by pointing out the importance of the establishment of adequate dietetic habits, avoiding obesity as well as high levels of apo B, and the establishment of continuous and prolonged physical activity as hygiene for the healthy life in children to prevent modifications in the apoprotein profiles which may include an atherogenic risk.
