MATERNAL INTERACTION QUALITY MODERATES EFFECTS OF PRENATAL MATERNAL EMOTIONAL SYMPTOMS ON GIRLS' INTERNALIZING PROBLEMS.

The role of mother-infant interaction quality is studied in the relation between prenatal maternal emotional symptoms and child behavioral problems. Healthy pregnant, Dutch women (N = 96, M = 31.6, SD = 3.3) were allocated to the "exposed group" (n = 46), consisting of mothers with high levels of prenatal feelings of anxiety and depression, or the "low-exposed group" (n = 50), consisting of mothers with normal levels of depressive or anxious symptoms during pregnancy. When the children (49 girls, 47 boys) were 23 to 60 months of age (M = 39.0, SD = 9.6), parents completed the Child Behavior Checklist (T.M. Achenbach & L.A. Rescorla, ), and mother-child interaction quality during a home visit was rated using the Emotional Availability Scales. There were no differences in mother-child interaction quality between the prenatally exposed and low-exposed groups. Girls exposed to high prenatal emotional symptoms showed more internalizing problems, if maternal interaction quality was less optimal. No significant effects were found for boys.

Prenatal maternal emotional complaints are associated with cortisol responses in toddler and preschool aged girls.

Associations between prenatal maternal emotional complaints and child behavioral and cognitive problems have been reported, with different relations for boys and girls. Fetal programming hypotheses underline these associations and state that the early development of the HPA-axis of the children may have been affected. In the present study, differences in cortisol responses of prenatally exposed and nonexposed children are examined for both sexes separately. Cortisol response patterns of a group preschool aged children that were prenatally exposed to high levels of maternal emotional complaints (N = 51) were compared to a nonexposed group (N = 52). Child saliva was collected at the start of a home visit (T1), 22 min after a mother-child interaction episode (T2), and 22 min after a potentially frustrating task (T3). Repeated measures analyses showed that prenatally exposed girls showed higher cortisol levels across the three episodes compared to nonexposed girls. No differences were found in boys. Maternal prenatal emotional complaints might be related to child HPA-axis functioning differently for boys and girls.

Sex differences in the relation between prenatal maternal emotional complaints and child outcome.

BACKGROUND: Sex differences are found in animal studies concerning the relationship between prenatal maternal stress and outcome of the offspring. Most human studies in this field have not addressed sex differences, although differences between boys and girls may elucidate the biochemical as well as psychological processes involved. Associations between prenatal maternal emotional complaints and behavioural problems of toddlers and preschoolers as assessed by both mothers and fathers are studied separately for boys and girls. METHODS: Healthy Dutch Caucasian singleton, pregnant women (N=444) answered questionnaires about anxiety and depression in every trimester of pregnancy. When their children (227 boys, 217 girls) were between 14 and 54 months old, both parents reported on their current feelings of depression and anxiety and on the behavioural problems of their children. RESULTS: Prenatal maternal emotional complaints were found to be associated with child behavioural problems both in boys and in girls, but in different ways. Prenatal maternal emotional complaints during the first trimester were associated with total and internalizing behavioural problems for boys. Emotional complaints during the third trimester were associated with total, internalizing, as well as externalizing behavioural problems for girls. CONCLUSIONS: Differentiation according to sex and information on timing of emotional complaints during pregnancy is needed in studies concerning the relation between prenatal maternal emotional complaints and child outcome.
