[Prevalence of anemia and iron deficiency in 12 year old school children from Jujuy]. / Prevalencia de anemia y deficiencia de hierro en escolares jujeños de 12 años.

Iron deficiency is highly frequent among adolescents. Its early detection can prevent the development of a ferropenic anemia, a serious condition. The problem has not been well studied in our country. The purpose of this work was to determine the frequency of iron deficiency and anemia in adolescents. The criteria considered were: hematocrit below 38%, b) saturation transferrin below 16%, c) ferritin below 15 ng/ml. The study was carried out in 2265 schoolchildren, 12 years old, of both sexes, in urban and periurban areas in the city of San Salvador de Jujuy (1250 a.s.l.). The following parameters were measured: hematocrit as well as serum iron and total iron binding capacity, both by colorimetric method. Ferritin was measured by ELISA. Anemia was not found. Iron deficiency as estimated by the iron functional component, was found in 25% of girls and 21% of boys and, through iron stores, in 28% of girls and 18% of boys. Iron deficiency stores in both sexes is the more relevant alteration, indicating that the population sample here studied constitutes a highly vulnerable group. The early detection of iron deficiency will help physical and intellectual development so that adequate sanitary policies are necessary for its prevention.

[Hematocrit values and prevalence of anemia in schoolchildren of Jujuy]. / Valores del hematocrito y prevalencia de anemia en escolares jujeños.

The hematocrit (Ht), as an indicator of anemia in individuals and populations, shows variations in relation to mesologic and genetic factors. Anemia is an endemic disease with insufficiently known prevalence in Argentina, in different age and risk groups and particularly in schoolchildren. The aim of this work was to study the variation of schoolchildren Ht in San Salvador of Jujuy city located at 1,200 m.a.s.l. in order to evaluate the prevalence of anemia and to relate these variations to the socio-economic characteristics of the population. The Ht data proceed from 17,580 schoolchildren of private and public schools. They were grouped by age, sex and socio-economic level. Were considered as anemic the children whose Ht was found: a) under a minimal value accepted for the 1200 m level; b) below 2 standard deviations. For the statistical analysis, ANOVA, chi 2 and correlation coefficient were employed. Independently of age, sex and socio-economic level, the average Ht values agree with those adjusted for the altitude. We observed: a) statistically significant intersex differences, males showing higher values than females; b) a trend to the Ht augmentation in relationship to the increase of the socio-economic level. Independently of the criterion used the prevalence of anemia was low in both sexes, age groups and in all socio-economic levels. Ht values: a) are representative of a schoolchildren population located at a moderate altitude; b) in spite of a trend to decrease in the low socio-economic level, this did not surpass, in most cases, the critical anemia level; c) are not indicative of malnutrition in the schoolchildren examined.
