Results: Young adults born at extremely low birth weight (prenatal adversity; = 64 = 23.14 years, = 1.26 years) had a lower alpha/delta ratio score compared to normal birth weight controls ( 76, = 23.60 years, = 1.09 years), while youth exposed to child maltreatment (postnatal adversity; = 39, = 16.18 years, = 1.15) had a higher alpha/delta ratio compared to controls ( = 23, = 16.00 years = 1.50 years).
Conclusions: Our results suggest that being exposed to pre- and post-natal adversity may have different long-term consequences on brain development. We speculate that these differences might be associated with some of the different functional outcomes known to characterize each type of adverse experience.

Early-life adversity during pre- and early post-natal phases can impact brain development and lead to maladaptive changes in executive behaviors. This increases the risk for a range of psychopathologies and physical diseases. Importantly, exposure to adversities during these periods is also linked to alterations in the orbito-frontal cortex (OFC) which is a key player in these executive functions.

Maternal smoking increases adverse risks for both the mother's pregnancy and the unborn child and remains disproportionately high among some Indigenous peoples. Decreasing smoking among pregnant Indigenous women has been identified as a health priority in New Zealand because of wide inequities in smoking-related harms. Using pre- and post-intervention questionnaires, this feasibility study assessed the acceptability and potential efficacy of a novel cessation program designed for Indigenous women by Indigenous experts utilizing traditional knowledge and practice.

Background: Cleft lip and/or palate is the most common congenital orofacial deformity, affecting 1/800 births. A thorough review of the literature has shown that children with cleft have poorer oral hygiene and dental health than other children, with higher levels of caries in both temporary and permanent teeth and poorer periodontal health. Cleft patients are treated by a multidisciplinary team that aims to provide comprehensive care from pre- or post-natal diagnosis to early adulthood and the end of growth.

Introduction: Fertility decision-making is an important factor affecting the Total Fertility Rate. Good communication between partners encourages shared decision-making and equal participation. Women's decision-making plays an important role in determining their reproductive health and fertility behaviour.

Sex steroids influence early organization of neural structures involved in expression of sexual behavior. A critical perinatal period during which testosterone surges occur has been identified in male rodents. Data are lacking for females, whose ovarian activity starts later in the postnatal period.
