Abstract
BACKGROUND

Generalized anxiety disorder (GAD) may be associated with an increased risk of future hypertension through psychophysiological stress pathways; however, this association must be interpreted carefully, considering medication use, lifestyle factors, clinic-based selection, and limited temporal information provided by baseline biomarkers.

AIM

To explore the potential impact of GAD on future hypertension risk and preliminarily analyze the roles of psychophysiological stress-related pathways (neuroendocrine, sympathetic activation, and inflammatory response) in the same.

METHODS

This was a prospective, observational cohort study. A total of 300 outpatients and physical examination participants from January 2023 to December 2024 at Southern Medical University Shenzhen Hospital were included; no participants had hypertension at baseline. The participants were divided into a GAD group (n = 96) and a non-GAD group (n = 204) according to the DSM-5 diagnosis and the GAD-7 scale. Data on general information, lifestyle factors, dietary salt intake, physical activity, family history, psychotropic/hypnotic medication use, and sleep quality were collected. Early morning serum cortisol, C-reactive protein, interleukin-6, 24-hour ambulatory blood pressure, and heart rate variability parameters were obtained. All participants were followed up for 12 months and sustained new-onset hypertension was recorded. Multivariate and sensitivity analyses were performed to assess the association between GAD and hypertension, while mediation analysis was used as exploratory statistical decomposition rather than causal pathway confirmation.

RESULTS

All 300 participants completed the 12-month follow-up; 50 cases of new-onset hypertension were observed. Incident hypertension occurred in 36/96 (37.5%) participants in the GAD group, significantly higher than 14/204 (6.9%) in the non-GAD group. After adjusting for demographic factors, body mass index, smoking and alcohol use, sleep quality, baseline blood pressure, family history of hypertension, psychotropic/hypnotic medication use, physical activity, and dietary salt intake, GAD remained associated with a higher risk of new-onset hypertension in the expanded penalized model (adjusted odds ratio = 2.31, 95% confidence interval: 1.23-4.38). Replacing the dichotomous GAD status with a continuous GAD-7 score yielded a consistent association. Compared to the non-GAD group, the GAD group showed higher levels of cortisol, C-reactive protein, and interleukin-6, and heart rate variability (HRV) indices indicated impaired sympathovagal balance. Exploratory mediation analysis suggested that increased cortisol levels and a standardized HRV composite jointly explained 32.5% of the association between GAD and incident hypertension, while inflammatory markers showed borderline or positive indirect-effect trends.

CONCLUSION

GAD was associated with a higher 12-month risk of sustained new-onset hypertension in this clinic-based cohort; this association persisted after adjustment for common clinical, medication-related, and lifestyle confounders. Elevated cortisol levels and reduced HRV may statistically explain part of this association; however, mediation findings should not be interpreted as definitive causal pathways. Clinically, dynamic blood pressure monitoring, anxiety assessment, medication review, sleep management, and lifestyle interventions should be considered in patients with GAD.

Core Tip: This prospective observational cohort study suggests that generalized anxiety disorder (GAD) is associated with future hypertension risk in a clinic-based population without baseline hypertension. Among the 300 participants, the 12-month incidence of sustained new-onset hypertension was higher in the GAD group (37.5% vs 6.9%). This association persisted after expanded adjustment for clinical variables, psychotropic/hypnotic medication use, physical activity, and dietary salt intake (adjusted odds ratio = 2.31). Patients with GAD also showed higher cortisol, C-reactive protein, and interleukin-6 levels and impaired heart rate variability. Exploratory mediation analysis supported cortisol and heart rate variability as possible statistical links; however, causal interpretation requires longer-term studies with repeated biomarker measurements.
