Lifetime exposure to air pollution and academic achievement: A nationwide cohort study in Denmark.

Recent research suggests a link between air pollution and cognitive development in children, and studies on air pollution and academic achievement are emerging. We conducted a nationwide cohort study in Denmark to explore the associations between lifetime exposure to air pollution and academic performance in 9th grade. The study encompassed 785,312 children born in Denmark between 1989 and 2005, all of whom completed 9th-grade exit examinations.

Maternal education and cognitive development in 15 European very-preterm birth cohorts from the RECAP Preterm platform.

Background: Studies are sparse and inconclusive about the association between maternal education and cognitive development among children born very preterm (VPT). Although this association is well established in the general population, questions remain about its magnitude among children born VPT whose risks of medical and developmental complications are high. We investigated the association of maternal education with cognitive outcomes in European VPT birth cohorts.

Gestational Age, Parent Education, and Education in Adulthood.

Background: Adults born preterm (<37 weeks) have lower educational attainment than those born term. Whether this relationship is modified by family factors such as socioeconomic background is, however, less well known. We investigated whether the relationship between gestational age and educational attainment in adulthood differed according to parents' educational level in 4 Nordic countries.

Social, demographic and health characteristics of men fathering children at different ages.

The aim of this study was to examine associations between selected sociodemographic, socioeconomic, and health characteristics and the rates of fatherhood in different age groups. We investigated rates between 2011 and 2015 in a population-based register study including all men born from 1945 to 1995 residing in Denmark in 2011. The study population consisted of 1,867,108 men who fathered 268,612 children during the follow-up.

The role of parental education on the relationship between gestational age and school outcomes.

Background: Individuals born preterm may experience difficulties beyond the neonatal period, such as poorer school outcomes. However, whether these outcomes are modified by family factors is less well-known.

Objectives: To investigate whether parental educational level modify the relationship of gestational age with completion of final examinations and grade point average in compulsory education.

Mortality Among Young Adults Born Preterm and Early Term in 4 Nordic Nations.

Importance: Adverse long-term outcomes in individuals born before full gestation are not confined to individuals born at extreme gestational ages. Little is known regarding mortality patterns among individuals born in the weeks close to ideal gestation, and the exact causes are not well understood; both of these are crucial for public health, with the potential for modification of risk.

Objective: To examine the risk of all-cause and noncommunicable diseases (NCD) deaths among young adults born preterm and early term.

'Standing together - at a distance': Documenting changes in mental-health indicators in Denmark during the COVID-19 pandemic.

There is a need to document the mental-health effects of the COVID-19 pandemic and its associated societal lockdowns. We initiated a large mixed-methods data collection, focusing on crisis-specific worries and mental-health indicators during the lockdown in Denmark. The study incorporated five data sources, including quantitative surveys and qualitative interviews.

Gestational Age and Socioeconomic Achievements in Young Adulthood: A Danish Population-Based Study.

Importance: The poor health outcomes associated with preterm birth are well established. However, it is less clear how small variations in gestational age, even within the term range, are associated with long-term opportunities and well-being, as measured by socioeconomic outcomes in adulthood.

Objective: To examine the association of gestational age at birth with educational achievement, income, and primary source of income in adulthood.

Educational disparities in perinatal health in Denmark in the first decade of the 21st century: a register-based cohort study.

Objective: To investigate socioeconomic differences in six perinatal health outcomes in Denmark in the first decade of the 21st century.

Design: A population-based cohort study.

Setting: Danish national registries.
