Whether it was associated with their mortality kept unknown. The objective of this study was to investigate the long-term mortality and analyze the association between SPA and this mortality in the specific context of rural elderly patients with hypertension.Patients and Methods: This study is a longitudinal investigation of the mortality in elderly patients with hypertension in rural Suzhou, China. Sociodemographic and clinical data, SPA, and six-year mortality were investigated. We used binary logistic regression and subgroup analyses to assess the effect of SPA at baseline on six-year mortality.Results: A total of 280 hypertensive patients aged 60 years and older participated in the study, of whom 21 died, with a six-year mortality rate of 7.5%. After controlling for covariates, the “Emotional representation” dimension (OR=2.824, 95% CI:1.034– 7.712) in SPA remained a risk factor for death. In subgroup analyses of the group aged 75 years and older, high scores on the “Timeline cyclical” (OR=14.125, 95% CI: 1.258– 158.593) and “Emotional representations” (OR=2.567, 95% CI:1.066– 6.182) dimensions were associated with a higher risk of death, while weekly nut intake may have mitigated the negative SPA effect on mortality.Conclusion: Poorer self-perception of aging was associated with a high risk of mortality in rural elderly patients with hypertension, while the habit of weekly nut intake might help reduce this risk in the group aged 75 years or older.Keywords: China, hypertension, mortality, rural population, self-perception
