BACKGROUND

Hypertension is a significant global health issue linked to high mortality and morbidity rates. It contributes not only to organ damage but also to psychological disorders such as anxiety and depression. Despite the rise in hypertensive patients experiencing these mental health issues, evidence remains insufficient.

OBJECTIVE

This systematic review and meta-analysis aimed to assess the prevalence of anxiety and depression among hypertensive patients.

METHODS

Observational studies published between 2020 and 2024 were sourced from PubMed, The Cochrane Library, and Google Scholar. The Newcastle-Ottawa Scale, adapted for cross-sectional studies, was utilized to evaluate study quality. A random-effects model was employed for meta-analysis to estimate the prevalence rates of anxiety and depression, alongside subgroup and sensitivity analyses to identify sources of heterogeneity.

RESULTS

Fifteen studies were included, with 14 eligible for quantitative analysis. The findings indicated a prevalence rate of 35% for depression (95% CI: 26%-44%) and 41% for anxiety (95% CI: 4%-78%) among hypertensive patients. Significant heterogeneity was observed in the studies (I²=98.3% for depression, I²=99.9% for anxiety). Subgroup analyses highlighted variability in assessment scales (p < 0.001), but not by region or population source. No publication bias was identified (p = 0.663 for depression, p = 0.710 for anxiety). Factors associated with depression included uncontrolled hypertension, female gender, marital status, and social support, while anxiety was linked to similar factors plus concerns about hypertension complications.

CONCLUSION

Depression and anxiety prevalence among hypertensive patients ranges from 30-42%. Uncontrolled hypertension and social support significantly impact mental health, with major barriers to psychiatric care compliance including economic constraints, lack of education, and comorbidities.
