Geriatric depression affects 12.95-28.4% of adults aged ≥ 60, yet treatment rates remain critically low globally. Lifestyle factors, particularly exercise and sleep demonstrate therapeutic potential, integrated interventions may exert synergistic effects on geriatric depression, though such interventions remain scarce. The Geriatric Exercise-Sleep Optimization (GESO) project aims to evaluate the clinical efficacy and cost-effectiveness of a combined exercise and sleep health intervention in alleviating depressive symptoms among community-dwelling older adults with depression, and exploring the potential underlying mechanisms. This is a stepped-wedge cluster-randomized trial (SW-CRT). A 12-week integrated exercise and sleep intervention will be implemented to all eligible participants during the study period. The primary aim is to evaluate the clinical efficacy in alleviating depressive symptoms. Secondary aims are to evaluate the additional health outcomes (i.e., quality of life, physical activity level, daily step count, sleep quality, and anxiety symptom), cost-effectiveness, and potential mechanisms. Costs will be aggregated and analyzed for economic evaluation. Costs will be aggregated and analyzed for economic evaluation. Salivary measured BDNF and irisin levels, and EEG-based brain function connectivity will be collected to assess potential intervention mechanisms. Mixed-effect linear regression models will be used to evaluate the effects of the integrated exercise-sleep intervention on primary and secondary outcomes. This study is expected to provide an effective and practical mode for an integrated exercise and sleep intervention among community-dwelling older adults with depression. Intended outcomes of the trial will facilitate changes in best practice to improve outcomes for this population.Trial registration Chinese Clinical Trail Registry ChiCTR2500107641, Registration date: 15 August 2025.

The hemoglobin levels in the peripheral blood of individuals living at high altitudes are significantly higher than normal levels. These levels are closely associated with atherosclerosis and cardiovascular events. This study aimed to investigate the correlation between hemoglobin levels in the peripheral blood and hypertension in high-altitude regions, providing a basis for preventing and treating primary hypertension in these regions. From May 2020 to May 2021, patients diagnosed with primary hypertension in plateau regions of China were selected as participants. The clinical data, including lifestyle habits and blood biochemical indicators, were collected from the clinical case database for patients meeting the inclusion criteria. The logistic regression analysis was performed to identify factors influencing carotid intima-media thickness in patients with primary hypertension in plateau regions. The ROC curve was plotted to analyze the impact of peripheral blood hemoglobin levels on hypertension, determine the hemoglobin threshold for predicting hypertension in plateau areas, and evaluate the predictive value of hemoglobin level for hypertension. A total of 200 patients (105 men with an average age of 64.8 ± 12.75 years and 95 women with an average age of 69.5 ± 11.54 years) were enrolled in this study. Logistic regression analysis revealed that age, CO Elevated hemoglobin levels contribute to the thickening of the carotid artery intima-media layer and hold predictive value for high-altitude hypertension.
