Childhood adversity is a risk factor for adult health outcomes, including obesity and hypertension. This study examines whether childhood adversity predicted mean arterial pressure through mechanisms of central obesity and leptin, adiponectin, and/or insulin resistance, and including dietary quality. 210 Black/African Americans and White/European Americans, mean age=45.8; ±3.3 years, were studied cross-sectionally. Path analyses were used to specify a chain of predictive variables in which childhood adversity predicted waist-hip ratio and dietary quality, circulating levels of hormones, and in turn, mean arterial pressure, adjusting for race, gender, and antihypertensive medications. Direct paths were found between childhood adversity, waist-hip ratio, and leptin levels and between leptin and dietary quality to mean arterial pressure. Systolic and diastolic blood pressures were similarly predicted. Early adversity appears to developmentally overload and dysregulate endocrine systems through increased risk for obesity, and through a direct impact on leptin that in turn, impacts blood pressure.
