“…The median dietary lead intake of 0.26 g /kg bw/day by children aged 0 ± 7 years in Region V was close to the 0.30 g /kg bw/day estimated mean for 2-year-old children in the FDA Total Diet Study (Gunderson, 1995), but lower than the mean intake of 0.42 g/ kg bw/day reported for 21 children aged 18±36 months in urban Omaha, Nebraska (Stanek et al, 1998). FDA has calculated a provisional tolerable total intake level (PTTIL) of 6 g /day for children aged 0 ±6 years (U.S. FDA, 1993).…”

A National Human Exposure Assessment Survey ( NHEXAS) field study was performed in U.S. Environmental Protection Agency (EPA) Region V, providing population-based exposure distribution data for selected elements in several personal, environmental, and biological media. Population distributions are reported for the 11 elements that were measured in water and dietary samples. Dietary intakes and home tap water concentrations of lead, arsenic, and cadmium were further examined for intermedia associations, for differences between dietary exposure for adults and children, and to estimate the proportion of the population above health-based reference values (dietary) or regulatory action levels or maximum contaminant levels (water). Water lead and arsenic concentrations were significantly associated with dietary intake. Intake of all elements was higher from solid foods than from liquid foods (including drinking water). Dietary intakes of Pb, As, and Cd were greater than those calculated for intake from home tap water or inhalation on a g /day basis. Median dietary intakes for the Region V population for Pb, As, and Cd were 0.10, 0.13, and 0.19 g / kg bw/day, respectively. While Pb, As, and Cd concentrations in the foods consumed by 0 to 6-year-old children were similar to or lower than those for adults, dietary intakes calculated on a body weight basis were 1.5 to 2.5 times higher for young children. Intrapersonal intake differences accounted for most of the variance in short-term (daily) dietary intakes for Pb and As, while interpersonal differences accounted for more of the intake variance for Cd. Only small percentages of the population exceeded health-based intake reference values or concentrations equal to regulatory levels in water for Pb, As, and Cd.

“…2. The shape of the CASE distribution most closely resembles that of the Stanek et al (1998) distribution, however, the geometric mean is closer to that of data collected by Charney et al (1980). The Freeman et al (2001) data exhibit the largest deviation from the simulated data.…”

“…Charney et al (1980) estimated a median value of lead on children's hands as approximately 511 lg/m 2 . Stanek et al (1998) found a mean of 323 lg/ m 2 and a standard deviation of 252 lg/m 2 . Melnyk et al (2000) measured a mean of 366 lg/m 2 and a standard deviation of 563 lg/m 2 .…”

“…Lead exposure in utero is associated with reduced NP and head circumference (Emory, Ansari, Pattillo, Archibold, & Chevalier, 2003;Stanek, et al, 1998), while DHA, an omega-3 fatty acid, positively correlates with look duration in preterm infants who receive supplements (Werkman & Carlson, 1996) or whose mothers show high blood concentrations of DHA at birth (Colombo, Kannass et al, 2004). An iron supplementation trial in Chile found no differences in scores on the Bayley Scales of Infant Development between supplemented and non-supplemented infants.…”

Speed of information processing and recognition memory can be assessed in infants using a visual information processing (VIP) paradigm. In a sample of 100 infants 6-8 months of age from Southern Ethiopia, we assessed relations between growth and VIP. The 69 infants who completed the VIP protocol had a mean weight z score of −1.12 ± 1.19 SD, and length z score of −1.05 ± 1.31. The ageappropriate novelty preference was shown by only 12 infants. When age was controlled, longest look duration during familiarization was predicted by weight (sr 2 = .16, p = .001) and length (sr 2 = .05, p =.058), and mean look duration during test phases was predicted by head circumference (sr 2 = . 08, p = .018) implying that growth is associated with development of VIP. These data support the validity of VIP as a measure of infant cognitive development that is sensitive to nutritional factors and flexible enough to be adapted to individual cultures.
