Abstract: Childhood adversity is one of the most important environmental risk factors that leads to stress cardiovascular dysregulation, which is innervated by the autonomic nervous system. However, few studies have examined the interaction effects of environmental factors and genetic polymorphisms on cardiovascular reactivity to stress among adolescents. Adopting a multilocus genetic profile score (MGPS) approach, the present study aimed to explore the associations between childhood adversity and adolescent cardiovascular reactivity to stress, and test the moderating role of the autonomic nervous system genetic polymorphisms.
Two independent samples (sample 1 included 256 adolescents, Mage =12.95 ± 0.79 years old; Sample 2 included 358 adolescents, Mage =12.98 ± 0.74 years old) were recruited from two middle schools in northwest China. Cardiovascular reactivity was induced by a speech task and a mental arithmetic task in sample 1 and sample 2, respectively.
Results showed that childhood adversity was negatively associated with cardiovascular reactivity to stress, and these associations were moderated by MGPS. Specifically, compared to adolescents with lower MGPS, those with higher MGPS exhibited lower (or blunt) cardiovascular reactivity to stress when exposed to high childhood adversity, and exhibited greater cardiovascular reactivity to stress when exposed to low childhood adversity.
Findings suggest that childhood adversity and autonomic nervous system genetic polymorphisms interactively impact stress cardiovascular function among adolescents, and have implications for interventions targeted at improving stress cardiovascular function in adolescents with childhood adversity.
