TI  - [Influence of iron status on attention and intellectual performance of a 
      population of Spanish adolescents].
PG  - 6-11
AB  - Dietetic, hematologic and biochemical data were used to asses the iron status of 
      a group of 64 adolescents (37 males and 27 females), aged 15 to 18 (mean age 
      15.94 +/- 0.76 years), who study in a High School in the comunidad Autonoma de 
      Madrid. All were asked to keep a dietary record during 5 days, one of which had 
      to be a sunday. Iron intake was estimated using the Food Composition Tables of 
      the Instituto de Nutricion (1990). The hematologic survey determined hemoglobin 
      hematocrit mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean 
      corpuscular hemoglobin concentration (MCHC), serum iron and serum ferritin. These 
      data were correlated with the scores obtained in the attention and school 
      capability test (AT), that gave information about the verbal (V), reasoning (R) 
      and calculus (C) capabilities. There is a positive correlation between MCV (r = 
      0.2705), MCH (r = 0.3370) ferritin (r = 0.3383) and attention. MCV (r = 0.2995), 
      MCH (r = 0.3998), MCHC (r = 0.3134) and ferritin (r = 0.3970) were also 
      correlated with the speed capability shown on the attention test and the 
      hemoglobin level was correlated with the calculus capability (r = 0.2905). The 
      students who obtained higher scores in the school capability test had also better 
      blood parameter values. This was statistically significant for serum ferritin in 
      males students and for hemoglobin and MCHC in female students. 19.6% of the 
      adolescents had ferritin levels lower than 12 ng/ml. Their intelligence test 
      scores were lower to those who had serum ferritin > or = 12 ng/ml.(ABSTRACT
