Background: This dissertation examines maternal genotypes and mother-infant attachment as moderators of the association between the early rearing environment and cortisol secretion. Study 1 examines whether DRD2, SLC6A3, and OXTR genes moderate the association between maternal history of care and maternal cortisol secretion. Study 2 examines mother-infant attachment as a moderator of the associations between maternal depressive symptoms and both infant and maternal cortisol secretion. Method: Mothers self-reported their history of care and depressive symptoms at infant age 16 months. At 17 months, mother-infant attachment was assessed in the Strange Situation Procedure (SSP). Salivary cortisol was assessed at baseline and at 20- and 40-minutes post-SSP. Buccal cells were collected for genotyping. Results: Study 1 revealed that maternal history of low care predicts elevated cortisol secretion, but only for mothers with 10-repeat alleles of SLC6A3 or G alleles of OXTR. Study 2 revealed that maternal depressive symptoms predict elevated cortisol secretion, but only for infants and mothers in non-secure attachment relationships. Conclusions: This dissertation enhances our understanding of the complex relations between the early rearing environment and maternal and infant cortisol secretion.

The effects of child sexual abuse (CSA) have been found to surpass generations as maternal history of CSA is associated with increased difficulties in sexually abused children. However, little is known about the mechanisms underlying this association. The present study aimed to test maternal mental health symptoms including psychological distress, post-traumatic stress disorder (PTSD) symptoms, and dissociation as mediators of the relationship between maternal CSA and children’s internalizing, externalizing, and dissociation symptoms in a large sample of sexually abused children. A total of 997 sexually abused children aged 3-14 years old and their mothers were recruited at five specialized intervention centers offering services to sexually abused children and their families. The children were divided into two groups depending on their mothers’ self-reported history of CSA. Mothers completed a series of questionnaires assessing their mental health and children’s functioning. Maternal history of CSA was associated with increased maternal psychological distress, PTSD symptoms, and dissociation following children’s disclosure of CSA. In turn, maternal psychological distress and maternal dissociation were associated with increased child internalizing, externalizing, and dissociation symptoms. Maternal PTSD symptoms were associated with child internalizing symptoms. Maternal mental health difficulties mediated the association between maternal CSA and sexually abused children’s maladaptive outcomes. Clinicians should assess for possible history of CSA in mothers of sexually abused children and determine how best to support them to cope with the aftermaths of their child’s disclosure and with their own traumatic past.

Background: There is steady increase in the prevalence of diabetes mellitus from 0.73% to current 2.4% in rural and 4.0% to 11.6% in urban areas. Familial clustering of diabetes may support a genetic predisposition to diabetes. With increase in the prevalence of diabetes there is increase in number of first degree relative as well, thus an increased risk of developing diabetes, will also increase. To study the plasma glucose levels in First-degree relatives of family member of type 2 diabetic patients was the objective of the present study.Methods: It is a descriptive observational study with 1020 individuals serially coming to our outpatient Department for Pre-employment Medical Health Check Up Annual Health Check Up were selected. These individuals have been enrolled for the study and their family history of diabetes was noted, their sugar levels and their lipid levels were estimated and their body mass index was calculated. The data thus collected and analyzed with excel.Results: 184 (18%) individuals were FDRs, were as 836 (82%) individuals were Non-FDRs. There were 754 (74%) males [131(17%) FDR and 623(83%) Non-FDR], were as 213 (26%) females [53(20%) FDR and 213(80%) Non-FDR], 61(6%) individuals were having Diabetic Mother, 91(9%) individuals had Diabetic Father and 32(3%) were those in whom both the Parents were Diabetic. It was found that maternal history has strong association for getting abnormal BSL levels as compared to a diabetic father as the RR of 9.82 (95% 4.84 to 19.95) in individuals with mother being diabetic, and RR of 1.54(95% 0.68 to 3.87) of father being diabetic.Conclusions: Family history of diabetes, maternal history of diabetes and history of both the parents having diabetes are risk factors for diabetes in FDRs.
