Related blood levels of testosterone and sex hormone-binding globulin in pregnant women to gender role behavior among 342 male and 337 female offspring at 3.5 years. Found that testosterone levels related linearly to girls' gender role behavior. Neither hormone related to boys' gender role behavior. Other factors, including older brothers or…

Reports a study of 110 newborn infants' responses to the heelstick procedure to draw blood samples, and of the responses of 40 of those infants to their first inoculations at two months of age. Discusses measures of distress; stability of reactivity across time; and individual differences and health of the infant as factors in reactivity. (NH)

Compares annual rates of neonatal, postneonatal mortality to annual rates of low birth weight, 1963-1982. Shows that same level of decline in incidence of low birth weight is associated with greater decline in mortality rates of non-White than White infants and for nonmetro than metro infants. Contains 15 references. (Author/DHP)

This paper reviews Asperger Syndrome, a form of developing autism with average intelligence, in 12 boys (ages 5 to late teens). Examination of family histories, medical history and findings, obstetric, and neonatal data found no common environmental factors and supports a brain damage hypothesis. (DB)

This paper presents two case studies of children who developed herpes virus infection in the intrauterine or early postnatal period and presented with features of autism around two years of age. Other research suggesting a link between herpes and autism is reviewed. (DB)

Examines relationships among prenatal characteristics of 121 adolescent mothers -- including cognitive readiness for parenting, intelligence, social support, and personal adjustment -- and intellectual-linguistic development, social-emotional functioning, and adaptive behavior of their children at three years of age. Only 28% of the children…

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988 - 2001. The analysis is unique for several reasons. First, we have over 800,000 births to women on Medicaid, the largest sample ever used to analyze prenatal participation in WIC. Second, we focus on measures of fetal growth distinct from…

Expression of the immediate-early genes (IEGs) has been shown to be induced by activity-dependent synaptic plasticity or behavioral training and is thought to play an important role in long-term memory. In the present study, we examined the induction and expression of the IEG-encoded protein Egr-1 during an in vitro neural correlate of eyeblink…

Background: Prenatal problems are among theorized etiologies for child disruptive behavior problems. A key question concerns whether etiological contributors are shared across the broad range of disruptive psychopathology or are partially or largely distinct. Method: We examined prenatal smoking exposure and low birth weight as risk factors for…

A study examined the readership of state cooperative extension offices' home learning programs--nine series of booklets of information about pregnancy, infant development, and parenting, mailed to parents in ten states to coincide with pregnancy stage and baby's age in months. The reading level of the series varied from sixth to eighth-grade…

During a period of increasing unemployment and decreased Medicaid eligibility, more women residents of low-income census tracts in Washington State received delayed prenatal care or none at all and delivered proportionately more infants of low birthweight. The incidence of maternal anemia also may have increased. (Author/GC)

Tests 242 newborns exposed prenatally to low levels of polychlorinated biphenyls from maternal consumption of contaminated lake fish. The Brazelton Neonate Scale was used to assess behavioral outcomes. Contaminated fish consumption predicted motoric immaturity, poorer labeling of states, a greater amount of startle, and abnormally weak…

Reviews the effects of malnutrition during pregnancy and before the age of three on children's brain development and subsequent mental development. Describes marasmus, kwashiorkor, and the incidence of malnutrition in South Africa. Discusses the relationship between the culture of poverty, malnutrition, and illegitimacy. Urges South Africans to…

Perinatal histories of 50 learning-disabled children (ages 7 to 12) with minimum neurological dysfunctions were evaluated (using a normative population for comparison) to discover if any relationship existed between pregnancy and birth complications and the development of learning disabilities. The experimental group had had a significantly higher…

A longitudinal study is evaluating the efficacy of a phenylalanine-restricted diet in reducing disabling conditions associated with maternal hyperphenylalaninemia. Titled the Maternal PKU Collaborative Study, it is studying 162 American and Canadian women and involves diet therapy, prenatal examinations, laboratory tests, nutritional evaluation,…
