OBJECTIVES The purpose of this work was to determine whether iron-deficiency anemia in infancy represents a risk factor for deficits in attention and memory development using event-related potentials. METHODS Artifact-free event-related potential data were obtained at 9 and/or 12 months from 15 infants with iron-deficiency anemia and 19 who were iron(More)
OBJECTIVES This study examined effects of iron deficiency anemia (IDA) on specific domains of infant cognitive function and the role of IDA-related socioemotional deficits in mediating and/or moderating these effects. METHODS Infants were recruited during routine 9-month visits to an inner-city clinic. IDA was defined as hemoglobin level <110 g/L with >(More)
OBJECTIVE To assess dose-response relationships between severity of iron deficiency (ID) and infant social-emotional behavior. STUDY DESIGN The study group was a cohort of 9- to 10-month-old African-American infants (n = 77 with final iron status classification). The infants were given oral iron for 3 months. Social-emotional outcomes included mother and(More)
OBJECTIVE This study was conducted to examine the relation between iron status and neurobehavioral development in premature infants. STUDY DESIGN Infants born before 34 weeks postmenstrual age and who were medically stable were studied. Anemia was defined as hemoglobin < or =10 g/Dl and low iron stores as a serum ferritin concentration < or =75 microg/l.(More)
Maternal iron status is thought to be related to postpartum depressive symptoms. The purpose of the present study was to evaluate the relationship between pre- and postnatal maternal iron status and depressive symptoms in pilot (n = 137) and confirmatory (n = 567) samples of Chinese women. Iron status was evaluated at mid- and late pregnancy and 3 days(More)
Iron deficiency has been shown to impair dopamine functioning in rodent models, but it is challenging to obtain evidence of such effects in human infants. Because spontaneous eye-blink rate may provide a noninvasive assessment of dopamine functioning, we hypothesized that eye-blink rate would be lower in infants with iron-deficiency anemia and would(More)
OBJECTIVE This study was conducted to compare quality of mother-infant interaction during feeding in infants with or without iron-deficiency anemia (IDA). METHOD Infants and caregivers were screened at their 9- to 10-month-old health maintenance visits at an inner-city clinic in Detroit. Those who were full-term and healthy received a venipuncture blood(More)
AIM To examine the relationship between maternal stress in early pregnancy and cord-blood ferritin concentration. METHODS The sample consisted of 140 pregnant women who lived in a region that was under rocket attack during a military operation (December 2008 to January 2009). Mothers in the stress group (n=63) were in their first trimester during this(More)
The ontogenetic development of postingestive inhibitory control of ingestion by an oil preload was examined in preweaning rats. Gastric preloads (5% b.wt) of water, mineral oil or corn oil were administered 5 min before a 30-min intake test in which pups licked milk from the floor of a test chamber. Preloads of corn oil decreased intake significantly(More)
PTSD elicits hypervigilance to trauma-related stimuli. Our novel research examined event-related potentials from Blood, Anatomy, and Morbid content derived from the Rorschach's traumatic content index (TCI). Participants included: 16 with PTSD, 24 trauma-exposed without PTSD (non-PTSD), and 16 non-traumatized Controls. P3 oddball paradigms were used with(More)
