Aim: To investigate developmental trajectories in early childhood and predictors of class assignment. Methods: Data were available for Gen2 infants at 12 (n = 2275), 24 (n = 1845) and 36 (n = 2110) months of age in the Raine Study. Latent growth class analysis was used to identify developmental trajectories based on the Ages and Stages…

We investigated the kinds of biological properties that children aged 3-6 years attribute to animals, plants, and artifacts by administering a property attribution task and eliciting explanations for the resulting property attributions. Findings indicated that, from the age of 3 years, children more frequently attribute properties to animals than…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…

Stunting has been negatively associated with children's development. We examined the range of height by testing hypotheses: (a) height is positively associated with children's development, with associations moderated by inflammation and (b) home environments characterized by nurturance and early learning opportunities is positively associated with…

Malnutrition and a lack of sufficient psychosocial support from caregivers both have a tremendous effect on children's development. Initiatives to support healthy child development in a context of poverty include caregiver interventions. There is growing evidence to support interventions that integrate psychosocial and nutritional support. The…

The present study examined Japanese children's and adults' awareness of the effects of psychological taste experiences on biological processes such as growth and illness. Studies 1 and 2 showed the following: (1) preschoolers tended to assume that good-tasting experiences would make one grow taller and gain more weight, while adults seldom…

We conducted a theory-driven process evaluation of a cluster randomized controlled trial comparing two types of complementary feeding (meat versus fortified cereal) on infant growth in Guatemala, Pakistan, Zambia and the Democratic Republic of Congo. We examined process evaluation indicators for the entire study cohort (N = 1236) using chi-square…

Causal inference in observational studies typically requires making comparisons between groups that are dissimilar. For instance, researchers investigating the role of a prolonged duration of breastfeeding on child outcomes may be forced to make comparisons between women with substantially different characteristics on average. In the extreme there…

Background: Early childhood malnutrition is associated with cognitive and behavioral impairment during childhood and adolescence, but studies in adulthood are limited. Methods: Using the NEO-PI-R personality inventory, we compared personality profiles at 37-43 years of age ("M" 40.3 years, "SD" 1.9) of Barbadian adults who had…

Background: Interaction between caregivers and children with severe impairments is closely related to the demands of daily activities. This study examines the relationship between interaction and the routine mealtime activity at home. Method: Patterns of interaction between a child (aged 6 years and 6 months) with severe speech and physical…

Aims: The human immunodeficiency virus (HIV) potentially causes a significant encephalopathy and resultant developmental delay in infected children. The aim of this study was to determine whether a home-based intervention programme could have an impact on the neurodevelopmental status of children infected with HIV. Method: A longitudinal,…

Women's postnatal depressive symptoms have been associated with many adverse outcomes for children. The current study examined the frequency association with relative risk between postnatal depressive symptoms and mothers' use of preventative infant health practices. The study used the Edinburgh Postnatal Depression Scale (EPDS) and Parental…

Immunological, endocrinological, and haematological abnormalities are relatively common in people with Down syndrome (Cuadrado & Barrena, 1996; Decoq & Vincker, 1995; Hestnes et al., 1991; Sustrova & Strbak, 1994; Nespoli, Burgio, Ugazio & Maccario, 1993; Kempski, Chessells & Reeves, 1997; Kivivuori, Rajantie, & Siimes, 1996; David et al., 1996;…

This book represents a synthesis of current knowledge about the physical, cognitive and social development of young children who live in the developing countries of Africa, Asia, Latin-America, and Oceania. The book develops five major themes: (1) It views child development in a comparative fashion, examining universal sequences in development as…

In 1977, a longitudinal study was initiated to assess the effectiveness of health services provided by Head Start. The study provided for 10 domains: pediatric health examinations, health history recordings, dental evaluation, anthropometric assessment, diet and nutrition assessment, and hematology evaluations, as well as for developmental,…
