Mating with close kin can lead to inbreeding depression through the expression of recessive deleterious alleles and loss of heterozygosity. Mate selection may be affected by kin encounter rate, and inbreeding avoidance may not be uniform but associated with age and social system. Specifically, selection for kin recognition and inbreeding avoidance may be more developed in species that live in f...
BACKGROUND Depression after childbirth is a major problem affecting 10-22% of all mothers. In Italy, postnatal depression has not yet been systematically studied. METHODS In this retrospective study we have sought to identify risk factors, assessed during pregnancy, and their importance for postnatal depression symptoms in a sample of 297 Italian women attending ante-natal classes organised b...
Introduction Postnatal depression is a common cause of morbidity but is rarely diagnosed or managed in busy primary care settings in most resource limited countries like Zimbabwe. Objectives This study sought to determine the prevalence of postnatal depression and establish factors associated with postnatal depression. Methods The study utilized a cross-sectional descriptive design where 29...
household food security remains a challenge in south africa. the national government instituted the integrated food security strategy (ifss) programme which identifies household agricultural production as an important element of improving household-level food security. agricultural extension is well positioned to help achieve this aim, but its current contribution is unknown. this study identif...
Maternal depression in the peri-natal period is associated with increased risk for young adult depression in offspring. This study explored mediation of these links via trajectories of child conduct and emotional problems (Strengths and Difficulties Questionnaire) from ages 4-16 years old in data from the Avon Longitudinal Study of Parents and Children cohort (n = 13373). Through gender-specifi...
In sexual reproduction the genetic similarity or dissimilarity between mates strongly affects offspring fitness. When mating partners are too closely related, increased homozygosity generally causes inbreeding depression, whereas crossing between too distantly related individuals may disrupt local adaptations or coadaptations within the genome and result in outbreeding depression. The optimal d...
Animal studies find that prenatal stress is associated with increased physiological and emotional reactivity later in life, mediated via fetal programming of the HPA axis through decreased glucocorticoid receptor (GR) gene expression. Post-natal behaviours, notably licking and grooming in rats, cause decreased behavioural indices of fear and reduced HPA axis reactivity mediated via increased GR...
