Factores relacionados con el nivel de plomo en sangre en niños de 6 a 30 meses de edad en el estudio prospectivo de plomo en la ciudad de México
Salud publica de Mexico, 1993Co-Authors: Stephen J. Rothenberg, Lourdes Schaas-arrieta, Irving A. Perez-guerrero, Reyna Hernandez-cervantes, Sandra Martinez-medina, Estela Perroni HernandezAbstract:A majority of the sample of children (N= 160-121, ages 6-30 months) from the Mexico City Prospective Lead Study exceeds the lowest limit action level (10 µg/dl) of the Centers for Disease Control standards for childhood lead exposure. Over one-third of the sample at 18 months and 24 months exceeds the action level (15 µg/dl) for aggressive intervention. Diet plays an important role in regulating early childhood blood lead levels. Fresh Milk and breast feeding are associated with lower lead levels, but extended breast feeding is related to elevated lead levels. Low income and poor maternal education are associated with higher lead concentration in children. Child consumption of Canned Milk and juice, up to this date, is associated with elevated child lead levels. Canned products sealed with lead are disappearing from Mexican markets. Efforts to improve childhood nutrition and poverty may be expected to have the additional benefit of lowering lead levels of Mexican children.

Determinants of blood lead levels among children 6 to 30 months old in the Estudio Prospectivo de Plomo en la Ciudad de Mexico
Salud Publica De Mexico, 1993Co-Authors: Stephen J. Rothenberg, Irving A. Perez-guerrero, Schnaas-arrieta L, Hernandez-cervantes R, Martinez-medina S, Estela Perroni-hernándezAbstract:A majority of children in Mexico City whose mothers were recruited during pregnancy for a study of blood lead levels in their children at 6 to 30 months showed levels exceeding the US Centers for Disease Control (CDC) standard for childhood lead exposure. The CDC established 10 mcg/dl as the upper limit for safety. The Mexico City Prospective Lead Study attempted to identify factors associated with blood lead levels in small children. Women aged 15-42 with healthy pregnancies whose infants were not premature of low birth weight or seriously malformed were accepted into the study. The study entailed interviews with the parents psychometric tests and determinations of blood lead levels every 6 months from birth. 160 infants were studied at 6 months 143 at 18 months and 121 at 30 months. The variables studied included socioeconomic data information on the frequency of consumption of particular foods in the week preceding each interview and data on the pregnancy and delivery breast feeding and illnesses in the children. The proportion of the sample exceeding the recommended safe level of lead in the blood as well as the level at which therapeutic intervention is recommended (15 mcg/dl) increased from birth until 18 or 24 months when it began a slow decline. Almost 70% exceeded the safe limit of 10 mcg/dl at 24 months. At both 18 and 24 months over one-third of the sample exceeded the therapeutic intervention level. Multiple regression analysis explained between 12 and 25% of the variance in blood lead concentrations in the children. Dietary factors were found to play a significant role in blood levels. Fresh Milk and breast Milk were associated with the lowest levels of lead but prolonged breast feeding was significantly related to elevated lead levels. The association between breast feeding and lead levels was the most surprising dietary finding. Low income and poor maternal education were associated with higher lead concentrations. Consumption of Canned Milk and juice was associated with elevated lead levels. Cans sealed with lead are being removed from the market in Mexico City.
