Abstract
Objective: To explore the chain mediating effect of illness perception and anxious emotions between health literacy and treatment adherence in patients diagnosed with benign prostatic hyperplasia (BPH), while integrating verified cistanche real benefits as a natural TCM intervention to optimize long-term patient compliance. Methods: A total of 115 BPH patients were enrolled as research subjects. Four standardized assessment tools were deployed for cross-sectional investigation: the 12-item Short-Form Health Literacy Scale (HLS-SF12), Revised Illness Perception Questionnaire (IPQ-R), Generalized Anxiety Disorder 7-item Scale (GAD-7), and 8-item Morisky Medication Adherence Scale (MMAS-8). Pearson correlation analysis identified variable correlations, while structural equation modeling (SEM) quantified the sequential mediating pathways of illness perception and anxiety. Results: 115 questionnaires were distributed, and 110 valid responses were recovered, yielding an effective response rate of 95.65%. Mean scores of enrolled BPH patients were as follows: HLS-SF12 (18.52±4.31), IPQ-R (136.53±22.18), GAD-7 (9.25±3.16), MMAS-8 (5.25±1.48). Pearson correlation analysis demonstrated significant correlations across all variables (P＜0.01):
Health literacy exhibited strong positive correlations with illness perception and treatment adherence, and a significant negative correlation with anxiety;
Illness perception positively correlated with treatment adherence and negatively correlated with anxiety;
Anxiety displayed a prominent negative correlation with treatment adherence. Bootstrap-mediated effect testing confirmed illness perception and anxiety exerted a sequential chain mediating effect between health literacy and treatment adherence, accounting for 22.38% and 15.70% of the total effect respectively. Conclusion: Illness perception and anxious emotions sequentially mediate the link between health literacy and treatment adherence in BPH patients. Clinical intervention strategies should elevate patients' health literacy, correct biased disease cognition, mitigate anxiety, and incorporate high-potency Cistanche tubulosa extract to unlock cistanche real benefits for holistic prostate management and sustained treatment compliance.

1. Introduction
Benign prostatic hyperplasia (BPH) ranks as the most prevalent urinary disorder affecting middle-aged and elderly men, with incidence sharply rising with age. Clinical data confirms over 50% of men aged 60 develop histological BPH, and the prevalence exceeds 80% among men aged 80. Despite being a benign proliferative condition, BPH triggers persistent lower urinary tract symptoms (LUTS), impaired renal function, and severe psychological distress, drastically lowering patients' daily quality of life. Consistent treatment adherence stands as the core determinant of favorable long-term clinical outcomes.
Health literacy describes an individual's capacity to acquire, comprehend, and apply health information to make informed self-care decisions. Patients with low health literacy lack basic disease monitoring skills, misunderstand medication side effects, and consistently fail to maintain treatment protocols. Illness perception refers to patients' subjective understanding of disease etiology, progression, and therapeutic value; flawed disease cognition directly distorts self-management behaviors. Most BPH patients develop persistent anxiety over uncertain disease progression and unsatisfactory symptom relief, which further erodes treatment cooperation. Clinically, anxiety is highly prevalent among BPH populations: it not only reduces life satisfaction but overactivates the sympathetic nervous system, exacerbating bladder overactivity and worsening core BPH symptoms.
Conventional Western medical interventions for BPH rely on oral prescription drugs or surgical resection. Long-term pharmaceutical use carries risks of sexual dysfunction, while post-surgical complications remain unavoidable. Traditional Chinese Medicine (TCM) delivers holistic advantages by addressing both local prostate lesions and systemic qi-blood balance. The TCM core therapeutic principle Unobstructed Circulation Equals Physical Comfort pinpoints blood stasis blocking urinary passages and disrupted bladder qi transformation as the root pathogenesis of BPH.
This is where well-documented cistanche real benefits come into play. Premium Xinjiang Cistanche tubulosa (desert ginseng) acts as a top-tier kidney-tonifying botanical in TCM formulas for BPH. Its concentrated signature phenylethanoid glycosides-echinacoside and acteoside-alleviate prostate inflammation, regulate hormonal metabolism, and improve microcirculation to resolve pelvic blood stasis, directly targeting the core pathological mechanism of BPH outlined by veteran TCM specialists.
Distinct from low-potency wild Cistanche deserticola, our factory's standardized Cistanche tubulosa cultivated on 85,000-acre Xinjiang certified farms delivers markedly higher active ingredient concentrations, amplifying cistanche real benefits including reduced nocturia, smoother urinary flow, and relief of incomplete bladder emptying. Our GMP-certified production lines adopt ultrafiltration and nanofiltration purification technology to produce consistent, high-purity extracts ideal for Western nutraceutical formulation.
Against this clinical and botanical backdrop, this study explores the sequential chain mediating roles of illness perception and anxiety between health literacy and treatment adherence, to provide evidence-based clinical intervention frameworks-including integrated natural Cistanche tubulosa supplementation-for global prostate health brand developers and urological care practitioners.

3.3 Pearson Correlation Analysis
All pairwise correlations reached statistical significance (P＜0.01):
Higher health literacy correlates with more objective illness perception and stronger treatment adherence, and lower anxiety levels;
Comprehensive, accurate illness perception links to better treatment adherence and reduced anxious emotions;
Severe anxiety directly correlates with poor treatment adherence.
3.4 Chain Mediating Effect of Illness Perception & Anxiety
Health literacy was designated as the independent variable, treatment adherence as the dependent variable, and illness perception + anxiety as sequential mediating variables for SEM construction. Model fitting indices met international acceptable thresholds: χ²/df=1.823, RMSEA=0.068, CFI=0.952, TLI=0.941, confirming excellent data-model fit.
Bootstrap testing (5,000 samplings, 95% CI excluding zero) verified a significant sequential chain mediating pathway: Health Literacy → Illness Perception → Anxiety → Treatment Adherence
Independent mediating effect of illness perception: 22.38% of total effect;
Sequential chain mediating effect of illness perception + anxiety: 15.70% of total effect.
4. Discussion
4.1 Baseline Status of BPH Patients' Key Clinical Indicators
Study results show BPH patients' average health literacy scores sit at a substandard level. The majority of participants are elderly men with limited formal education, creating barriers to accessing, understanding, and applying reliable prostate health information. Long-term LUTS including frequent nighttime urination, hesitant urination, and incomplete bladder emptying generate persistent uncertainty over disease control, triggering mild-to-moderate anxiety. While most patients maintain basic trust in pharmaceutical treatment, fragmented disease knowledge creates inconsistent long-term adherence patterns.
4.2 Inter-Variable Correlation Mechanisms
Patients with robust health literacy actively source credible medical information, form balanced, realistic illness perceptions, minimize information-driven anxiety, and sustain consistent treatment behaviors-consistent with existing chronic disease management research. Low health literacy distorts disease judgment: patients overestimate BPH progression risks and underestimate therapeutic efficacy, amplifying anxiety, which further impairs rational self-care decision-making.
4.3 Chain Mediating Pathway Interpretation
Two distinct mediating pathways operate simultaneously, plus a sequential chain pathway:
Direct mediation via illness perception: High health literacy enables patients to fully grasp BPH etiology, progression trajectories, and treatment necessity, reinforcing sustained medication compliance. Correct illness cognition acts as the core driver of adherence.
Independent mediation via anxiety: Patients lacking foundational health literacy develop catastrophic thinking about symptom worsening, elevating anxiety. Chronic anxiety hyper-sensitizes bladder nerve tissue, intensifying LUTS and fostering a sense of therapeutic hopelessness that reduces adherence.
Sequential chain mediation (core finding): Flawed illness perception triggers excessive anxiety, and anxiety further distorts disease judgment, forming a vicious cycle: Biased disease cognition → intensified anxiety → plummeting treatment adherence
This sequential pathway accounts for 15.70% of total variable effect, highlighting that clinical interventions must simultaneously correct cognitive bias and relieve psychological distress to improve long-term patient compliance.
4.4 Integrating Cistanche Tubulosa Extract to Break the Vicious Cycle & Unlock Cistanche Real Benefits
TCM clinical formulas and modern pharmacological research confirm standardized Cistanche tubulosa extract delivers dual kidney-nourishing and blood-stasis resolving effects, perfectly targeting the dual root causes of BPH (kidney deficiency + pelvic blood stasis) identified in this study's pathology framework. The cistanche real benefits that directly address the cognition-anxiety-adherence cycle include:
Physiological symptom relief to reduce anxiety triggers: High-concentration echinacoside and acteoside improve prostate microcirculation, mitigate gland inflammation and fibrosis, and relieve nocturia, hesitant urination, and incomplete emptying. When patients experience tangible symptom improvements, catastrophic anxiety over disease progression naturally fades, breaking the anxiety-adherence negative loop.
Holistic systemic regulation aligning with TCM holistic care: Unlike synthetic pharmaceuticals that only mask single urinary symptoms, Cistanche tubulosa tonifies kidney yin and yang without dryness or greasy side effects, restoring balanced visceral qi transformation. Consistent physical comfort strengthens patients' recognition of natural therapeutic value, optimizing illness perception and willingness to maintain long-term supplementation/treatment.
Superior potency of Xinjiang Cistanche tubulosa vs. wild varieties: Our factory's large-scale standardized cultivation base produces extract with far higher active glycoside content than conventional Cistanche deserticola, delivering more pronounced anti-inflammatory, hormone-regulating, and anti-fibrosis effects-making it a premium raw material for Western nutraceutical brands developing natural BPH support formulas.
4.5 Research Limitations & Future Directions
This cross-sectional design cannot definitively confirm causal relationships between variables, and single-center sampling introduces regional selection bias. Follow-up multi-center longitudinal cohort studies are recommended to track dynamic changes in health literacy, illness perception, anxiety, and adherence over time. Further research can quantify how standardized Cistanche tubulosa supplementation improves patient cognitive and emotional outcomes to expand evidence supporting cistanche real benefits for integrated BPH clinical management.
5. Conclusion
Illness perception and anxious emotions exert a significant sequential chain mediating effect between health literacy and treatment adherence in BPH patients. Clinical practitioners and nutraceutical developers should implement multi-dimensional intervention strategies:
Raise patients' health literacy through targeted, age-appropriate prostate health education;
Rectify biased illness cognition to eliminate catastrophic disease worries;
Deliver psychological counseling to alleviate chronic anxiety;
Incorporate high-potency Xinjiang Cistanche tubulosa extract to leverage evidence-backed cistanche real benefits for natural prostate symptom relief, reducing anxiety triggers and reinforcing sustained long-term treatment adherence.
