Association of depressive symptoms and hypertension prevalence, awareness, treatment and control among USA adults

OBJECTIVE: The aim of this study was to measure hypertension prevalence, awareness, treatment and control by depressive symptoms among USA adults. METHOD: Using the National Health and Nutrition Examination Survey data from 2007 to 2018 ( n = 28 532), depressive symptoms were categorized as 'none or minimum', 'mild', 'moderate' and 'moderately severe or severe' by the Patient Health Questionnaire. Hypertension was assessed by history, blood pressure measures and antihypertensive medication use. Adjusted prevalence rates and adjusted prevalence ratios (APRs) of hypertension prevalence, awareness, treatment and control were measured. RESULTS: By depressive, the adjusted prevalence of hypertension (32.0, 34.2, 37.3 and 36.6%), awareness (80.6, 83.9, 85.7 and 89.8%) and treatment (73.1, 75.2, 78.6 and 83.9%) increased with advanced depressive symptoms, respectively (all P < 0.001). However, no difference in hypertension control was noted after full adjustment. Compared with those with no or minimum depressive symptoms, APRs of hypertension prevalence for mild, moderate and moderately severe or severe depressive symptom were 1.07 (1.02-1.12), 1.16 (1.107-1.262) and 1.15 (1.05-1.26), respectively. The corresponding APRs were 1.04 (1.003-1.08), 1.06 (1.01-1.11) and 1.11 (1.06-1.17) for hypertension awareness, and 1.03 (0.98-1.07), 1.08 (1.02-1.14) and 1.15 (1.08-1.22) for hypertension treatment, respectively. CONCLUSION: Among USA adults, depressive symptoms were significantly associated with hypertension prevalence, awareness and treatment, but not with hypertension control. When managing hypertension, healthcare providers should be aware of the mental health status.
