Long-Term Recall Error in Retrospective Family Surveys
Recall questions provide the possibility of obtaining longitudinal information in cross-sectional surveys and are often used in family research. Yet, recall instruments may suffer from measurement issues. This study links a recent cross-sectional survey that includes recall histories of all unions involving cohabitation to administrative cohabitation records for Denmark and assesses the recall error in cohabitation status histories. Under mild as…
Magnitude and determinants of excess total, age-specific and sex-specific all-cause mortality in 24 countries worldwide during 2020 and 2021
INTRODUCTION: To examine the impact of the COVID-19 pandemic on mortality, we estimated excess all-cause mortality in 24 countries for 2020 and 2021, overall and stratified by sex and age. METHODS: Total, age-specific and sex-specific weekly all-cause mortality was collected for 2015-2021 and excess mortality for 2020 and 2021 was calculated by comparing weekly 2020 and 2021 age-standardised mortality rates against expected mortality, estimated b…
A Joint Model for Longitudinal and Time-to-event Data in Social and Life Course Research
Longitudinal studies including a time-to-event outcome in social research often use a form of event history analysis to analyse the influence of time-varying endogenous covariates on the time-to-event outcome. Many standard event history models however assume the covariates of interest to be exogenous and inclusion of an endogenous covariate may lead to bias. Although such bias can be dealt with by using joint models for longitudinal and time-to-…
Immigration, mortality, and national life expectancy in the Nordic region, 1990–2019
Immigrants have higher life expectancy at age 1 than the native-born in Denmark, Finland and Norway do from 1990 to 2019.•Immigrants in Denmark, Finland and Norway increasingly enhance national life expectancy at age 1 over time.•Immigrants in Sweden have lower life expectancy at age 1 than native-born in Sweden do in 1990, but similar levels by 2019.•The effect of immigrants on national life expectancy at age 1 in Sweden transforms from negative…
Does Lolland-Falster make people sick, or do sick people move to Lolland-Falster? An example of selective migration and mortality in Denmark, 1968-2017
Long-term selective in-migration of vulnerable persons was behind the gradual build-up of the currently high mortality in Lolland-Falster compared to the rest of Denmark. In particular, people of working age in-migrating to Lolland-Falster contributed to this disparity
The stillbirth sex ratio as a marker of population health among live‐born males in Denmark, 1835‐1923
OBJECTIVES: We know little about whether an elevated stillbirth sex ratio (ratio of male to female stillbirths) gauges stronger selection in utero against frail male gestations and therefore predicts greater male infant survival. An alternative scenario could involve a "low endowment" case in which pregnancy cohorts show both excess male stillbirths and elevated mortality risk among male live births. We exploit the longest sex-specific stillbirth…

Interpregnancy Interval and Risk of Adverse Pregnancy Outcomes
Family of origin and educational inequalities in mortality
Circumstances in the family of origin have short- and long-term consequences for people's health. Family background also influences educational achievements - achievements that are clearly linked to various health outcomes. Utilizing population register data, we compared Swedish siblings with different levels of education (1,732,119 individuals within 662,095 sibships) born between 1934 and 1959 and followed their death records until the end of 2…
The educational gradient in cardiovascular risk factors
About one third of the educational gradients in modifiable CVD risk factors may be explained by factors that siblings share. This implies that childhood environment is important for the prevention of CVD
Declines in stillbirth and neonatal mortality rates in Europe between 2004 and 2010
BACKGROUND: Stillbirth and neonatal mortality rates declined in Europe between 2004 and 2010. We hypothesised that declines might be greater for countries with higher mortality in 2004 and disproportionally affect very preterm infants at highest risk. METHODS: Data about live births, stillbirths and neonatal deaths by gestational age (GA) were collected using a common protocol by the Euro-Peristat project in 2004 and 2010. We analysed stillbirths…
Health promotion in primary and secondary schools in Denmark
In a Danish context, schools' participation in health promotion was rather stable from 2006 to 2010 and unrelated to the measured characteristics of the schools and their students
The educational gradient in coronary heart disease
BACKGROUND: Independently of cardiovascular disease (CVD) risk factors, cognitive ability may account for some of the excess risk of coronary heart disease (CHD) associated with lower education. We aimed to assess how late adolescence cognitive ability and midlife CVD risk factors are associated with the educational gradient in CHD in Norway. METHODS: In a cohort of 57 279 men born during 1949-1959, health survey information was linked to militar…
Breastfeeding Practices in Relation to Country of Origin Among Women Living in Denmark
The objective of this study was to describe breastfeeding practices and to compare the risk of suboptimal breastfeeding of women living in Denmark according to country of origin, and further to examine how socio-economic position and duration of stay in the country affected this risk. Information on breastfeeding of 42,420 infants born 2002-2009 and living in eighteen selected Danish municipalities was collected from the Danish Health Visitor's C…
Oral health as a risk factor for mortality in middle-aged men
BACKGROUND: There is evidence of an association between poor oral health and mortality. This association is usually attributed to inflammatory and nutrition pathways. However, the role of health behaviours and socioeconomic position has not been adequately examined. The aims of this study were to examine the association between oral health and premature death among middle-aged men and to test whether it was explained by socioeconomic position and…
Contribution of Maternal Age to Preterm Birth Rates in Denmark and Quebec, 1981–2008
Objectives. We sought evidence to support the hypothesis that advancing maternal age is potentially causing a rise in preterm birth (PTB) rates in high-income countries. Methods. We assessed maternal age-specific trends in PTB using all singleton live births in Denmark (n = 1 674 308) and Quebec (n = 2 291 253) from 1981 to 2008. We decomposed the country-specific contributions of age-specific PTB rates and maternal age distribution to overall PT…
Socioeconomic inequality in birth weight and gestational age in Denmark 1996-2007
Sex differences in child and adolescent mortality by parental education in the Nordic countries
BACKGROUND: Socioeconomic position inequalities in infant mortality are well known, but there is less information on how child mortality is socially patterned by sex and age. OBJECTIVE: To assess maternal and paternal socioeconomic inequalities in mortality by sex, whether these differences vary by age and country, and how much of the sex differences can be explained by external causes of death. METHODS: Data on all live-born children were receiv…
A comparative study of educational inequality in the risk of stillbirth in Denmark, Finland, Norway and Sweden 1981–2000
BACKGROUND: The stillbirth rates in Denmark, Finland, Norway and Sweden are among the lowest in the world, but socioeconomic disparities in stillbirth still exist. This study examined the educational patterns in the risk of stillbirth in Denmark, Finland, Norway and Sweden from 1981 to 2000. METHODS: From the national birth registries, all singleton live births and stillbirths with a gestational age of at least 28 weeks were selected in Denmark (…
P1-337 Social inequality in mortality
Introduction The aim of this study was to examine to which degree the often demonstrated association between educational status and mortality is confounded by family characteristics, that is environment in childhood and genetic setup. To disentangle an independent causal effect of educational status on mortality from selection mechanisms, we used a discordant sibling design making it possible to control for the shared early life environment and t…
Parental socioeconomic position and development of overweight in adolescence
The levels of overweight and obesity among adolescents are high and continue to rise. Results from this study suggest that the inverse social gradient in overweight becomes steeper for girls and emerges for boys in late adolescence (age span 15 to 21 years). Late adolescence seems to be an important window of opportunity in reducing the social inequality in overweight among Danish adolescents
Ethnic disparity in stillbirth and infant mortality in Denmark 1981–2003
OBJECTIVE: Ethnic minorities constitute a growing part of the Danish population but little is known about ethnic disparity in early life mortality in this population. The aim of this study was to investigate ethnic disparities in stillbirth risk and infant mortality in Denmark from 1981 to 2003. METHODS: From population-covering registries, all live and stillbirths of women from the five largest ethnic minority groups and of women from the (Danis…
Time is on whose side? Time trends in the association between maternal social disadvantage and offspring fetal growth. A study of 1 409 339 births in Denmark, 1981–2004
BACKGROUND: Fetal growth is highly socially patterned and is related to health across the life course, but how the social patterns of fetal growth change over time remains understudied. The time trends in maternal social disadvantage in relation to fetal growth were examined in the context of a universal welfare state under changing macroeconomic conditions over a 24-year period. METHODS: All births in Denmark from 1981 to 2004 were included, and…
Social inequality in fetal growth
OBJECTIVE: To examine the socioeconomic patterns and time trends in fetal growth in Denmark, Finland, Norway, and Sweden from 1981 to 2000. DESIGN AND SETTINGS: Data on all live-born singleton births was drawn from national population registries in each of the four countries (Denmark n = 1,077,584; Finland n = 400,442; Norway n = 929,458; Sweden n = 1,761,562). MAIN OUTCOME MEASURE: Slope index of inequality (SII) and mean differences in birthwei…
IQ in late adolescence/early adulthood, risk factors in middle age and later all-cause mortality in men
OBJECTIVE: To examine the role of potential mediating factors in explaining the IQ-mortality relation. DESIGN, SETTING AND PARTICIPANTS: A total of 4316 male former Vietnam-era US army personnel with IQ test results at entry into the service in late adolescence/early adulthood in the 1960/1970s (mean age at entry 20.4 years) participated in a telephone survey and medical examination in middle age (mean age 38.3 years) in 1985-6. They were then fo…
