Maternal exposure to buprenorphine, but not methadone, during pregnancy reduces social play behavior across two generations of offspring.

Rationale: The prevalence of newborns exposed to medications for opioid use disorder (MOUD), such as methadone or buprenorphine, during pregnancy is increasing. The opioid system plays a crucial role in regulating and shaping social behavior, and children prenatally exposed to opioids face an increased risk of developing behavioral problems. However, the impact of prenatal exposure to MOUD on offspring's social behavior during adolescence and adulthood, as well as potential intergenerational effects, remains largely unexplored.

Effects of prenatal exposure to methadone or buprenorphine and maternal separation on anxiety-like behavior in rats.

Background: The use of medications for opioid use disorder such as methadone or buprenorphine is increasing among pregnant women. However, long-term effects of this treatment on the children's health are not well understood. A key challenge is distinguishing the effects of opioid exposure from other confounding factors associated with human opioid use, such as reduced maternal care.

Qualitative evaluation of the implementation of "Tuning in to Kids" in Norwegian Kindergartens.

Background: From January to June 2020, 22 FUS kindergartens across Norway implemented Tuning in to Kids for Kindergarten Teachers (TIK-KT) as part of a randomized control trial (RCT). Between the evaluation of an intervention and use of it in daily practice, a research-to-practice gap can often occur. The theory of planned behavior constituted the theoretical basis for the qualitative interviews that were administered to explore these gaps.

Trends in the prevalence of breastfeeding up to 6 months of age using structured data from routine child healthcare visits.

Aim: The Norwegian Action Plan for a Healthier Diet (2017-2021) set the target that 25% of infants should be exclusively breastfed for 6 months by 2022. Our aim was to determine trends in the prevalence and duration of breastfeeding in the municipality of Bergen.

Methods: Data on breastfeeding status in 2010-2018 were extracted from a standardised electronic medical record kept by public child health centres and recorded as exclusive, partial or none, at 6 weeks and 6 months of age.
