Sixty-one extremely preterm (EP) very low birth weight (VLBW) children (< 29 wk and < 1,500 g) born in 1987-1990 and 44 normal birth weight children (NBW) (> 37 wk and > 2,500 g) were matched for age, sex, and socioeconomic status (SES). Mediator variables were evaluated at a hospital at 5 years and 9 months. Behaviors were evaluated at school at 7 years by peers, teachers, and parents. When compared with NBW children, EP/VLBW children had poorer IQ and neuromotor development. At school, EP/VLBW children were evaluated by peers as more sensitive/ isolated, and by teachers and parents as more inattentive and hyperactive than NBW. When mediators were introduced, the previously significant relation between prematurity and behavior problems disappeared. Hyperactive and inattentive behaviors were explained by a specific working memory factor for the latter, and by a general intellectual delay for the former, whereas sensitive/isolated behaviors were best explained by neuromotor delays. Inattentive behaviors were also related to family adversity. At school age, extreme prematurity had thus an indirect effect on behaviors via specific and nonspecific intellectual and neuromotor delays.

The present study sought to determine whether a relationship can be established between a measure of psychological state of stress and level of immunoglobulin of the A class (IgA) in saliva. To this end, 44 dentistry students were tested on four occasions; two occasions were stress inductive (examination situation), and two occasions were free of any academic stressor. At each session, the participants were asked to fill out the stress rating instrument, and unstimulated whole saliva samples were obtained. Salivary IgA was measured by a microplate Enzyme Linked Immunosorbent Assay (ELISA). A significant difference in the level of salivary IgA was observed only for the most polarized contrast, ie, between final exam and end of summer vacation (p less than .01). A weak negative correlation between the level of salivary IgA and the stress rating was observed (r = -0.25) only at the final exam. Our results suggest that assaying immunoglobulin A in saliva to measure stress may not be as useful in psychophysiological research as expected.

Participants in Study 1 were 147 11-year-olds of whom 49 (29 females and 20 males) were reported by their parents to have been born prematurely. Participants in Study 2 were 84 11-year-old boys, 28 of whom were born with a birthweight less than 2000 grams. These at-risk subjects were followed for a period of two years. Subgroups within both study groups were matched with control groups using gender, age, and the school environment as common factors. Children in the target classes of Study 1 were classified using the Revised Class Play (Masten, Morison, & Pelligrini, 1985) and the Peer Nomination Inventory (Perry, Kusel, & Perry, 1988). In Study 2, the children completed the Pupil Evaluation Inventory (PEI) (Pekarik, Prinz, Liebert, Weintraub, & Neale, 1976). Findings suggest that aggressive behaviour is not related to birth status and that birth status is not linked to prosocial behaviour associated with sociability and likeability. However, both studies showed that children (boys and girls alike) born as premature or low birthweight infants, expressed greater levels of internalised social behaviour. These findings suggest that infants born premature and/or with a low birthweight may be less socially competent with their peers during their school-age years.
