Adverse childhood experiences (ACEs) include exposure to abuse (verbal and physical), neglect, and household dysfunction during childhood. ACEs have long-lasting health impacts including increased risk for cardiovascular disease (CVD) and hypertension in adulthood. However, it is not clear how ACE exposure impacts CVD risk earlier in the life course, particularly in adolescence. To address this gap in knowledge, in this study we hypothesized that ACE exposure is associated with abnormal ambulatory blood pressure (ABP) profiles in adolescents, with an increased incidence of ambulatory hypertension phenotypes that have normal casual clinic BP [e.g., masked hypertension (MH) or blunted nocturnal dipping (BND)]. We utilized 24-h ambulatory BP monitoring (ABPM; Spacelabs) and casual clinic BP to construct a profile of adolescents with and without ACEs. Abnormal ABP profiles included the following categories: ambulatory hypertension (AH, elevated ABP and casual clinic BP ≥95 th percentile for age, sex, and height), white-coat hypertension (WCH, elevated casual clinic BP with normal ABP), MH (normal casual clinic BP with elevated ABP), or BND (drop in ABP < 10% during sleep). This study included 78 male and female adolescents (median age=16) recruited from Children’s of Alabama Pediatric Clinics. Exclusion criteria included known CVD and antihypertensive medication. Participants recorded wake and sleep times in a diary. Based on the ACE questionnaire, 51 (65%) of adolescents experienced at least 1 ACE. The prevalence of abnormal ABP profiles was similar between the group with ACE exposures vs. the group without ACE exposures (34% vs. 36%; P =0.87). In participants with ACE exposure (n=51), 9% had AH, 6% had MH, 19% had WCH, 43.1% had systolic BND and 22% had diastolic BND. In participants without ACEs (n=27), 4% had AH, 4% had MH, 29% had WCH, 37% had systolic BND and 15% had diastolic BND. Further analysis with covariates are necessary. These results suggest that adolescents with ACEs have similar prevalence of abnormal ABP overall, but higher prevalence of individual ABP phenotypes such as AH, MH, and BND compared to adolescents without ACEs.

Adverse childhood experiences (ACEs), such as abuse, neglect, and household dysfunction, have been associated with increased risk of cardiovascular disease (CVD) in adulthood. Understanding how ACEs affects blood pressure during early life is key for the development of early interventions that may reduce the risk of future CVD. We hypothesized that exposure to ACEs is associated with detrimental hemodynamic parameters during adolescence. This study included 78 male and female adolescents (median age=16, range=13-18) recruited from Children’s of Alabama hospital. Exclusion criteria included cardiovascular or renal disease and antihypertensive medication. An oscillometric blood pressure (BP) monitor was used to measure 24-h ambulatory BP. ACE exposure was measured with the Adolescent Life Change Event (ALCES) questionnaire and was prevalent, with 65% (51 of 78) of participants experiencing 1 ACEs. The mean cumulative ACE score was 1.4±0.2. ACE exposure was not correlated with gender, race, age, or body mass index (BMI). Linear regression models were utilized to link ACE exposure (0 versus 1 ACEs) with 24-h mean arterial pressure (MAP), systolic BP (SBP), diastolic BP (DBP), and pulse wave velocity (PWV). Race and gender were included as covariates. Mean 24-h DBP was significantly (p=0.04) higher in participants with ACE exposure (65.9±0.7 mmHg, n=51) compared to those with no ACE exposure (64.1±0.9 mmHg, n=27); this association was independent of covariates. Since BMI was significantly correlated with SBP, PWV, and MAP, additional models included BMI as a covariate. Both ACE exposure (p= 0.02) and BMI (p<0.001) were associated with increased PWV, while the interaction between ACE exposure and BMI was negatively associated with PWV (p=0.02). Mean 24-h SBP and MAP were not significantly associated with ACE exposure. The finding that ACE exposure is associated with elevated DBP and PWV and not with SBP is in accordance with previously reported results in young adults and suggests that ACEs may alter autonomic pathways leading to CVD and hypertension. Interventions targeted at individuals with ACE exposure early in life could lower the risk of arterial stiffness and in turn the cascade of events leading to CVD.
