Clarifying Associations between Childhood Adversity, Social Support, Behavioral Factors, and Mental Health, Health, and Well-Being in Adulthood: A Population-Based Study
Sheikh, Mashhood Ahmed; Abelsen, Birgit; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-25)Previous studies have shown that socio-demographic factors, childhood socioeconomic status (CSES), childhood traumatic experiences (CTEs), social support and behavioral factors are associated with health and well-being in adulthood. However, the relative importance of these factors for mental health, health, and well-being has not been studied. Moreover, the mechanisms by which CTEs affect mental ... -
Coloring of the past via respondent’s current psychological state, mediation, and the association between childhood disadvantage and morbidity in adulthood
Sheikh, Mashhood Ahmed (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-31)<p><i>Objective</i>: Many researchers view retrospective reports with skepticism. Indeed, the observed association between retrospectively-reported childhood disadvantage (CD) and morbidity in adulthood has been criticized as an artefactual correlation driven by the psychological state of the respondent at the time of reporting (current psychological state). The aim of this study was to assess the ... -
Confounding and Statistical Significance of Indirect Effects: Childhood Adversity, Education, Smoking, and Anxious and Depressive Symptomatology
Sheikh, Mashhood Ahmed (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-02)The life course perspective, the risky families model, and stress-and-coping models provide the rationale for assessing the role of smoking as a mediator in the association between childhood adversity and anxious and depressive symptomatology (ADS) in adulthood. However, no previous study has assessed the independent mediating role of smoking in the association between childhood adversity and ADS ... -

Moreover, the analytical assumptions employed when assessing mediation in social and psychiatric epidemiology are rarely explained. The aim of this paper was to explain the intermediate confounding assumption, and to quantify differential recall bias in the association ... -

Sheikh, Mashhood Ahmed; Abelsen, Birgit; Olsen, Jan Abel (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-12)<p><i>Background</i>: Previous methods for assessing mediation assume no multiplicative interactions. The inverse odds weighting (IOW) approach has been presented as a method that can be used even when interactions exist. The substantive aim of this study was to assess the indirect effect of education on health and well-being via four indicators of adult socioeconomic status (SES): income, management ... -

However, disease-specific immune mechanisms in SMI are not known yet. Recently, dyslipidemia has been linked to systemic inflammasome activation, and elevated atherogenic ... -
Leisure time physical activity and future psychological distress: A thirteen year longitudinal population-based study
Sheikh, Mashhood Ahmed; Vancampfort, Davy; Stubbs, Brendon (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-27)A number of cross-sectional studies have suggested that physical activity (PA) is negatively associated with psychological distress in adulthood.

The aim of this paper was to assess the mediating role of quantity and quality of social support in ... -
