A health ecological model study of subjective cognitive decline among hypertensive patients in rural Shanxi, China.
Over 80% of rural hypertensive patients screened positive for subjective cognitive decline.
A health ecological model study of subjective cognitive decline among hypertensive patients in rural Shanxi, China.
Hypertension and subjective cognitive decline (subjective cognitive decline) frequently co-occur, consistent with broader multimorbidity patterns observed in aging populations and highlighting the need for targeted assessment of associated factors.
This study aimed to test the hypothesis that multi-level factors across the five Health Ecological Model (Health Ecological Model) layers are independently associated with subjective cognitive decline among hypertensive patients in rural China, and to identify specific associated factors within each layer.
Were categorized into non-subjective cognitive decline (subjective cognitive decline-Q9 score < 5) and subjective cognitive decline (≥ 5) groups based on self-reported cognitive symptoms.
Percentage of hypertensive patients whose self-reported symptoms met criteria for subjective cognitive decline.
Multi-level factors were significantly associated with subjective cognitive decline.
In the Individual Characteristics Layer, advanced age (OR = 1.042, 95% CI 1.010 ~ 1.074), family history of hypertension (OR = 2.352, 95% CI 1.550 ~ 3.570), hypertensive complications (OR = 3.049, 95% CI 1.680 ~ 5.534) and moderate hypertension risk level (OR = 1.847, 95% CI 1.149 ~ 2.968) were associated with higher odds of subjective cognitive decline.
These findings identify multi-level factors associated with subjective cognitive decline in this population, highlighting potential areas for integrated prevention strategies, though longitudinal studies are needed to establish their predictive value.
