The risk of abnormalities and morbidity among live births increases with advanced maternal age. Explanations for this elevated morbidity invoke several maternal mechanisms. The relaxed filter stringency (RFS) hypothesis asserts that mothers, nearing the end of their reproductive lifespan, reduce the stringency of a screen of offspring quality in utero based on life-history traits of parity and ...

Physical activities for a few days can increase brain-derived neurotrophic factor (BDNF) mRNA in rat hippocampus. To investigate the influence of maternal exercise during pregnancy on rat pup hippocampal BDNF mRNA, we studied its expression by a semi-quantitative RT-PCR method after young pregnant rats were exercised on a motor driven treadmill. Pups of exercised mothers had significantly incre...

Predictors of change in fathers' and mothers' perceptions of child caregiving involvement were examined. Middle-class 2-parent families (131 mothers and 98 fathers) with a target school-age child participated. Fathers and mothers completed annual questionnaires for 3 consecutive years. Latent growth curve modeling suggested that fathers were likely to increase their relative contribution to chi...

In an eight-year review (1991 to 1998) of all consecutive coroners' files in Québec, Canada, the authors identified a total of 34 cases of victims who were killed by their mothers. Most victims were less than six years of age, and there were several cases in which multiple siblings were murdered. There were 27 mothers in the sample, and 15 of those women committed suicide after the filicide. A ...

A previously calculated predictive model for health risk selects infants who suffer 4-5 times more morbidity than their unselected peers. Preliminary results suggested that this risk is related to maternal neurotic symptomatology. To evaluate this hypothesis, 52 consecutive mothers whose infants had a positive predictive score (Group 1) and 52 in whom this was negative (Group 2) were evaluated ...

The challenge of newborn health faced by India is more than any other country in the world. Globally out of 3.9 million, 30% neonatal deaths occur in India. A Quasi-experimental study was undertaken to assess the effectiveness of an ‘Instructional Teaching Programme’ (ITP) on the Knowledge of Postnatal Mothers regarding Newborn Care in multi-specialty, teaching hospital in Uttarakhand. Total 62...

Background: Raising awareness of mothers has an important role to preventing neonatal severe hyperbilirubinemia. We aimed to investigate the role of educational intervention on the knowledge and practice of the mothers with icteric newborns. Materials and Methods: This study was interventional study with interventional and control group. Study population consisted of 384 consecutive parents of ...

This study investigated the abusive behavior and parenting styles of 7 rhesus macaque mothers with infants born in 2 consecutive years. All subjects lived in captive social groups and were observed during the first 12 weeks of infant life. With the exception of 1 individual, mothers were generally consistent in the frequency with which they abused their successive infants. Similarities were als...
