Les conséquences biologiques des l'adversité sociale
Lay summary

Les inégalités sociales en matière de santé sont un phénomène omniprésent. Au cours des dernières années, la recherche a commencé à aborder la question de la façon dont le statut socioéconomique éventuellement "passe sous la peau" (gets under the skin). Des études humaines et animales ont identifié plusieurs processus interdépendants à travers lequel l'environnement social pourrait être intégré biologiquement, y compris une dysrégulation de l'axe hypothalamo-hypophyso-surrénalien, les processus inflammatoires, la fonction et la structure neuronale, et les mécanismes épigénétiques.

Ce projet de recherche se concentrera sur les troubles cardio-métabolique, qui montrent un fort gradient socio-économique. L'objectif est d'étendre l'étude des inégalités sociales en matière de santé et leurs déterminants en intégrant une analyse des mécanismes biologiques, la régulation des gènes en particulier, reliant l'adversité sociale tout au long de la vie aux maladies cardio-métaboliques.

Ce projet de recherche permettra d'évaluer:

1) Si le statut socio-économique à l'enfance est associée à la méthylation de l'ADN et à l'expression des gènes, et dans quelles régions du génome ces différences apparaissent;

2) Dans quelle mesure les différences socio-économiques dans la méthylation de l'ADN et l'expression des gènes contribuent à expliquer les différences socio-économiques dans l'activité inflammatoire;

3) Si la durée de l'exposition à un bas statut socio-économique tout au long de la vie a un impact sur la méthylation de l'ADN et l'expression des gènes.

Ce projet de recherche permettra de mieux comprendre les voies biologiques et sociales menant de l'adversité sociale au risque de maladies cardio-métabolique à. En outre, cette recherche établira dans quelle mesure les conséquences indésirables sur la santé 'une exposition sociale défavorable en début de vie sont potentiellement réversibles.

Abstract

Social inequalities in health are a ubiquitous phenomenon. Conversely, research still has to provide a comprehensive understanding of the mechanisms underlying them. In the last years, research started addressing the issue of how socioeconomic status eventually “gets under the skin”. Human and animal studies have identified several interrelated processes through which the social environment could be embedded, including dysregulation of the hypothalamic-pituitary-adrenal axis, inflammatory processes, neural function and structure, and, ultimately, epigenetic mechanisms. These studies cover a promising new field of research, and several questions remain to be addressed: 1.Studies examining the biology of social adversity have generally described socioeconomic differences in biological markers, but the actual contribution of these intermediate steps to social inequalities in chronic diseases has rarely been evaluated. Further, few studies have evaluated the interactions between lifestyle-related risk factors and biological markers. 2.Some new lifestyle factors potentially implicated in the etiology of socioeconomic differences in health, such as inadequate sleep, have been under-researched. 3.The influence of early life vs. adult socioeconomic status on the biological pathways leading to diseases remains unknown, as well as the extent to which the impact of early life exposure to social adversity can be modified later in life. This research project will focus on cardio-metabolic disorders, which show a strong gradient in their social distribution and whose burden on the most disadvantaged sections of society is rapidly increasing worldwide. The overarching aim is to extend the study of social inequalities in health and their determinants by incorporating an analysis of the biological mechanisms, and gene regulation in particular, linking lifetime social adversity to cardio-metabolic disease. This follow-up project will be specifically devoted to the study of the relationship between socioeconomic status and gene regulation.This research project will assess: 1)Whether SES in early life is associated with DNA methylation and gene expression, and in which regions of the genome these differences appear; 2)To what extent SES differences in DNA methylation and gene expression contribute to explain SES differences in inflammatory activity; 3)If duration of exposure to low SES and SES trajectories over the lifecourse have an impact on DNA methylation and gene expression. This research project will provide a better understanding of the social and biological pathways leading from lifetime socioeconomic adversity to adult life cardio-metabolic disease risk. This will not only add further observations on the role of exposure in early life in shaping health through adulthood, but will also clarify to what extent exposure to early life social adversity has an impact on adult health through behavioural vs. biological pathways. Moreover, this research will establish the extent to which the undesirable health consequences of adverse social exposure in early life are potentially reversible. Last but not least, an epigenome-wide analysis of socioeconomic differences in gene regulation will allow new insight to be gained into the mechanisms through which the social environment has an impact on health. Information on epigenome-wide gene expression and DNA methylation will be collected in a subsample of 750 participants of the SKIPOGH II study. The multidisciplinarity (social epidemiology, cardiovascular, cardio-metabolic and genetic epidemiology, public health, sleep medicine, internal medicine, and molecular biology) characterizing this research project offers potential to produce novel and innovative answers to the question of how socioeconomic status over the lifecourse leads to disease decades later.
