The Role of Discrimination in Social Safety and its Interplay with Adolescents’ Mental Health and Substance Use
Discrimination, as experienced by adolescents, represents a major societal issue with implications for mental health and risky health behaviors. Yet the interplay between these factors in the context of social safety in urban living environments remains insufficiently understood and was explored in the current study. Participants were 1,675 Dutch adolescents (Mage = 17.44 years, SD = 0.36; 56.6% girls) who participated in the ABCD-study. This sub…
Understanding Affective Symptoms and Substance Use in Older Adolescents in an Urban Context
Global urbanization may present mental health challenges for youth. We investigated relationships between affective symptoms, substance use, and urban characteristics in 17–18-year-old adolescents from the Amsterdam Born Children and their Development study ( N = 1682). Objectively measured urban neighbourhood characteristics (e.g. safety, poverty) were obtained from the Geoscience and Health Cohort Consortium in addition to self-report assessmen…
Associations Between Early-Pregnancy Vitamin D Status and Postpartum Depressive and Anxiety Symptoms
OBJECTIVE: Maternal postpartum depressive and anxiety symptoms are risk factors for subsequent maternal and child mental health problems. Little is known about the potential role of antepartum vitamin D and C-reactive protein (CRP) in the etiology of maternal postpartum affective symptoms. We investigated associations between antepartum vitamin D status and postpartum depressive and anxiety symptoms and whether antepartum CRP mediated these assoc…
Long-term effects of unintended pregnancy on children
Several studies investigated short-term risks of children born from unintended pregnancies, however evidence about long-term risks is lacking. We aimed to examine whether children born from unintended pregnancies experience psychosocial problems up into adolescence. This study is based on the longitudinal birth cohort study 'Amsterdam Born Children and their Development' (n = 7784). Unintended pregnancy was measured as a multidimensional construc…
Modelling individual infancy growth trajectories to predict excessive gain in BMI z-score
Models' performances varied significantly across model structures and growth measures. Developing the optimal model requires extensive testing of the many possibilities
The Long-Term Impact of Maternal Anxiety and Depression Postpartum and in Early Childhood on Child and Paternal Mental Health at 11–12 Years Follow-Up
Our results indicate that fathers and children seem to be affected only to a small extent by maternal postpartum anxiety or depression
A System Dynamics and Participatory Action Research Approach to Promote Healthy Living and a Healthy Weight among 10–14-Year-Old Adolescents in Amsterdam
This paper describes the design of the LIKE programme, which aims to tackle the complex problem of childhood overweight and obesity in 10-14-year-old adolescents using a systems dynamics and participatory approach. The LIKE programme focuses on the transition period from 10-years-old to teenager and was implemented in collaboration with the Amsterdam Healthy Weight Programme (AHWP) in Amsterdam-East, the Netherlands. The aim is to develop, implem…
Maternal Underestimation of Child’s Weight at Pre-School Age and Weight Development between Age 5 and 12 Years
The relationship between maternal underestimation of child's weight and higher weight development indicates a need for promoting a realistic perception of child's weight, this is also the case if the child has a normal weight
Disadvantaged neighborhoods, birth weight, and problem behavior in five- and six-year-old pre-school children
The explanatory role of maternal feeding practices
Association between pre-pregnancy weight status and maternal micronutrient status in early pregnancy
Objective Inadequate maternal micronutrient status during pregnancy can lead to short- and long-term health risks for mother and offspring. The present study investigated the association between pre-pregnancy weight status and micronutrient status during pregnancy. Design Maternal blood samples were collected during early pregnancy (median 13, interquartile range 12–15 weeks) and were assayed for serum folate, ferritin, Fe and vitamin B 12 . Regr…
Do Neighborhood Characteristics in Amsterdam Influence Adiposity at Preschool Age
In general, child adiposity at age 5-6 years was not independently associated with neighborhood characteristics, although a small relationship between child %BF and both neighborhood SES and perceived safety cannot be ruled out. At this young age, familial and individual factors probably play a more important role in influencing child adiposity than neighborhood characteristics
Screen time and cardiometabolic function in Dutch 5–6 year olds
We found no convincing evidence for an association between TV or PC time and cardiometabolic function in apparently healthy 5-6 yr olds
Racial/ethnic and immigrant differences in early childhood diet quality
Objective To assess racial/ethnic differences in the diet in young children and the explanatory role of maternal BMI, immigrant status and perception of child's weight. Design Among white, black and Hispanic 3-year-olds, we used negative binomial and linear regression to examine associations of race/ethnicity with foods and nutrients assessed by a validated FFQ. Setting Project Viva, Boston (MA), USA. Subjects Children aged 3 years ( n 898). Resu…
Maternal cell phone and cordless phone use during pregnancy and behaviour problems in 5-year-old children
BACKGROUND: A previous study found an association between maternal cell phone use during pregnancy and maternal-reported child behaviour problems at age 7. Together with cell phones, cordless phones represent the main exposure source of radiofrequency-electromagnetic fields to the head. Therefore, we assessed the association between maternal cell phone and cordless phone use during pregnancy and teacher-reported and maternal-reported child behavi…
Socioeconomic inequalities in lipid and glucose metabolism in early childhood in a population-based cohort
The socioeconomic gradient in cardiovascular risk factors seems to emerge in early childhood. In absence of underlying mechanisms these empirical findings are relevant for public health care and further explanatory research
Overweight at age two years in a multi-ethnic cohort (ABCD study)
Turkish and Moroccan children in the Netherlands have 2- to 3-fold higher odds for being overweight at age 2 years, which is largely attributed to maternal pre-pregnancy BMI and weight gain during the first 6 months of life. Further study on the underlying factors of this early weight gain is required to tackle ethnic differences in overweight among these children
Comparison of growth between native and immigrant infants between 0–3 years from the Dutch ABCD cohort
Most remarkable differences were found in the BMI and weight measurements for age charts. Especially girls from mothers born in Turkey and Morocco had an increasingly heavier weight for their age than girls from mothers born in the Netherlands
Maternal Depressive Symptoms in Relation to Perinatal Mortality and Morbidity
OBJECTIVE: To explore whether 1) maternal depressive symptoms during pregnancy are associated with preterm birth (PTB), small for gestational age (SGA), a low Apgar score and child loss; 2) maternal smoking mediates the associations; and 3) the associations differ by ethnic background. METHODS: Pregnant women in Amsterdam were approached during their first prenatal visit to participate in the Amsterdam Born Children and their Development study. T…
Cardio-metabolic risk in 5-year-old children prenatally exposed to maternal psychosocial stress
Main strengths of the proposed study are the longitudinal measurements during three important periods (pregnancy, infancy and childhood), the extensive measurement of maternal psychosocial stress with validated questionnaires and the thorough measurement of the children's cardio-metabolic profile. The availability of several confounding factors will give us the opportunity to quantify the independent contribution of maternal stress during pregnan…
The effect of neighbourhood income and deprivation on pregnancy outcomes in Amsterdam, The Netherlands
BACKGROUND: Studies suggest that the neighbourhoods in which people live influence their health. The main objective of this study was to investigate the associations of neighbourhood-level income and unemployment/social security benefit on pregnancy outcomes: preterm delivery, small for gestational age (SGA), pregnancy-induced hypertension (PIH) and miscarriage/perinatal death in Amsterdam. METHODS: A random sample of 7883 from 82 neighbourhoods …
First-Trimester Working Conditions and Birthweight
Objectives. We investigated the relationship between women's first-trimester working conditions and infant birthweight. Methods. Pregnant women (N = 8266) participating in the Amsterdam Born Children and Their Development study completed a questionnaire gathering information on employment and working conditions. After exclusions, 7135 women remained in our analyses. Low birthweight and delivery of a small-for-gestational-age (SGA) infant were the…
Overcommitment to Work Is Associated With Changes in Cardiac Sympathetic Regulation
Objective: Work stress is associated with an increased risk for cardiovascular disease (CVD). Exaggerated cardiovascular reactivity to work-related stressors or incomplete recovery after work is a proposed mechanism underlying this increase in risk. This study examined the effects of work stress on 24-hour profiles of the pre-ejection period (PEP), a measure of cardiac sympathetic activity, obtained from ambulatory measurement of the impedance ca…
Work Stress and Metabolic and Hemostatic Risk Factors
OBJECTIVE: A high level of work stress has been associated with cardiovascular disease. However, the pathophysiological mechanisms underlying this association remain unclear. This study examined the effect of work stress on a cluster of metabolic and hemostatic risk factors. METHODS: Blood was collected three times, on the first, third, and fifth day of a work week, from 124 middle-aged, white-collar workers. Metabolic measures were insulin, gluc…
