Child behaviour is a main concern for parents of 3-year-olds.

Aim: The aim of this study was to describe parental concerns about child health and behaviour and their sociodemographic predictors in 3-year-olds, in relation to the national guidelines of well-baby clinics.

Methods: The study included parents of 33 526 children in Stockholm who had completed a questionnaire prior to a routine visit to a well-baby clinic at age 3 years. Multivariate regression was used to analyse predictors for concerns.

Unintended Perinatal Health Consequences Associated With a Swedish Family Policy.

Importance: The 1980 and 1986 Swedish so-called speed premium policies aimed at protecting parents' income-based parental leave benefits for birth intervals shorter than 24 and 30 months, respectively, but indirectly encouraged shorter birth spacing and childbearing at older ages, both risk factors for several perinatal health outcomes. Whether those policy changes are associated with perinatal health remains unknown.

Objective: To evaluate the association between the 1980 and 1986 speed premium policies and perinatal health outcomes.

Cardiovascular Disease and Risk Factors in Individuals With a History of Out-of-home Care.

Background: Exposure to childhood out-of-home care (foster family and residential care) is associated with an increased risk of ill-health and disability in adulthood, but the risk for cardiovascular disease has not previously been studied longitudinally.

Methods: This was a national cohort study generated from linkage of a range of population-based registers, resulting in a national cohort of 881 731 of whom 26 310 (3.0%) had a history of out-of-home care.

Narcotic offences and drug use disorders among young refugees in Norway.

Aims: We examined the patterns of healthcare utilisation for drug use disorders (DUDs) and charges related to narcotics among young refugees in Norway considering the role of sex, country of origin and condition of arrival (accompanied versus unaccompanied minors).

Methods: Based on national registers, sex-stratified Cox regression models were used to estimate hazard ratios to assess the risk of being charged with a narcotics offence and the use of healthcare services related to DUDs. The sample consisted of 15,068 young refugees and 573,241 young Norwegians born in Norway to two Norwegian-born parents.
