Abstract P210: Systolic Blood Pressure Trajectories From Childhood to Adulthood and Depression in Middle Age: The Bogalusa Heart Study
Introduction: Few studies have examined the long term patterns of blood pressure change in relation to depression in middle age.
Methods: We examined data from the Bogalusa Heart Study, a long-term community-based observational study of a biracial cohort, with first measurements in childhood in 1973. Men and women (n=909) who completed the Center for Epidemiologic Studies Depression Scale (CES-D) in 2010 with at least two childhood and two adult SBP measurements were included. CES-D scores were categorized using established cut points (<8, 8-15, >15). Discrete mixture modeling was employed to identify trajectory groupings of (SBP), adjusted for race (time-independent) and body mass index (time-varying). The association between SBP trajectory and CES-D scores were determined using multivariable logistic regression adjusted for antihypertensive use, education, and physical activity in 2010.
Results: Mean (±SD) age was 43.1±4.5 years, 57.9% were female, and 31.7% were Black. 27.7% of participants were current smokers in 2010. Mean (SD) BMI was 31.0 (7.7). We identified four SBP patterns: always low but slightly increasing (46.8%), low and modestly increasing (22.6%), healthy and stable (21.8%), and profoundly increasing (8.9%). Relative to the largest group, the multivariable adjusted odds ratio (OR) of higher CES-D categorization, i.e. more depressed, for the modestly increasing was 1.47 (95% CI, 1.01-2.15), for the stable, 0.96 (95% CI, 0.66-1.39), and for the profoundly increasing, 1.93 (95% CI, 0.66-1.39). Each additional year of education was associated with 33% decreased odds of higher CES-D categorization (OR=0.67, 95% CI 0.59-0.77).
Conclusions: Trajectories of SBP from childhood through adulthood are associated with depression in middle age. Individuals with increasing SBP may benefit from depression screening in early adulthood.
