Sex differences in the associations between blood pressure and anxiety and depression scores in a middle-aged and elderly population: The Irish Longitudinal Study on Ageing (TILDA)
Background Anxiety and depression are considered risk factors for cardiovascular diseases (CVDs), but their relationship to blood pressure (BP) is still uncertain. Lifestyle factors and age-related comorbidities may confound these relationships. Our study aimed to evaluate the associations between BP and anxiety and depression scores in a population aged ≥49 years. Methods Data on 8504 participants from The Irish Longitudinal Study on Ageing (TILDA) were analyzed for associations between BP and anxiety and depression questionnaire scores, accounting for relevant confounding factors. Results Multivariable analyses showed negative associations between systolic BP and anxiety and depression scores, independent of age, body mass index (BMI), marital status, education level, smoking status, alcohol consumption, level of physical activity, self-reported CVDs (≥2) and antihypertensive medication use in men (coefficient=−0.112, P=0.013; coefficient=−0.051, P=0.026) but not in women (coefficient=-0.001, P=0.855; coefficient=-0.005, P=0.556). Diastolic BP was not associated with anxiety or depression scores in either men (coefficient=−0.018, P=0.223; coefficient=−0.001, P=0.924) or women (coefficient=−0.007, P=0.338; coefficient=−0.015, P=0.293) after adjusting for these same confounding factors. After a follow-up of 4 years, lower BP in subjects not using antihypertensive medications was significantly associated with more anxiety and depression events. Limitation Time-varying confounding factors may have interfered with our results. Conclusion Our results show that systolic BP in a middle-aged and elderly population is negatively associated with anxiety and depression scores in men but not women after adjustment for a range of lifestyle factors. These results contrast with the predisposition of anxious or depressed participants to CVDs in later life when decades of unhealthy lifestyles have persisted.
