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…
Impact of psychosocial stressors on type 2 diabetes among migrants and non-migrants in The Netherlands
Work stress, home stress, and adverse life events differentially influence T2D risk in diverse populations, with effects pronounced in Dutch, Moroccan and African Surinamese origin groups. Interventions targeting psychosocial stress may help reduce T2D in diverse populations
Individual and neighborhood determinants of depressive symptoms in ethnic minorities in the urban Helius sample
Ethnic minorities in Europe experience an increased risk of depressive symptomatology. This is believed to be the result of the interplay between different factors at the individual (e.g., psychological, socioeconomic, cultural) and the neighborhood level (e.g., social cohesion, resources, ethnic diversity). This study sheds light on the interplay between variables using cross-sectional data from 13, 507 individuals from five ethnic minority grou…
The Association between Post-Traumatic Stress Disorder and Problematic Alcohol and Cannabis Use in a Multi-Ethnic Cohort in The Netherlands
(1) Background: Ethnic minorities exhibit a higher prevalence of post-traumatic stress disorder (PTSD), while results for problematic substance use among ethnic groups remain mixed. PTSD and problematic substance use often co-occur; however, the impact of ethnicity on this association has not yet been investigated. (2) Methods: Self-report data on problematic alcohol/cannabis use (AUDIT/CUDIT) and presence of severe PTSD symptoms (PSS-SR) of N = …
Exploring the mechanisms underlying increased risk of depressive disorder in ethnic minority populations in Europe
The Covid-19 pandemic and temporal change in metabolic risk factors for cardiovascular disease
The coronavirus disease 2019 (COVID-19) pandemic, including the restrictive measures taken to reduce the spread of the virus, negatively affected people's health behavior. We explored whether the pandemic also had an effect on metabolic risk factors for cardiovascular disease (CVD) in women and men. We conducted a natural experiment, using data from 6962 participants without CVD at baseline (2011-2015) of six ethnic groups of the HELIUS study in …
Association between Depressed Mood and Sleep Duration among Various Ethnic Groups—The Helius Study
Background: We examined the association between depressed mood (DM) and sleep duration in a multi-ethnic population in Amsterdam, and the extent to which DM accounts for both short and long sleep. Methods: Cross-sectional data using 21,072 participants (aged 18-71 years) from the HELIUS study were analyzed. Sleep duration was classified as: short, healthy, and long ( Results: DM was significantly associated with short sleep in all ethnic groups a…
Associations Between Child Maltreatment, Autonomic Regulation, and Adverse Cardiovascular Outcome in an Urban Population
In a large, multi-ethnic urban-population cohort study we observed a positive association between number of endorsed child maltreatment types and self-reported aCVO but not autonomic regulation, over and above the effect of relevant demographic, health, and psychological factors. Future studies should examine the potential role of the dynamics of autonomic dysregulation as potential underlying biological pathways in the association between ACEs a…
The mental health of trafficked persons
This chapter addresses mental health problems prevailing in trafficked persons (TPs), particular stressors which may elicit these, and how treatment may help. The Equator approach entails weekly group meetings offering psycho-education and stabilising exercises to TPs staying in the shelter, and a behavioural screening of participants in close co-operation with on the spot counsellors. Trafficked men and women are frequently exposed to severe psy…
