Abstract:Background
Both the quality of sleep and depression impact short‐term memory (STM) while they influence each other. However, the underlying mechanisms are not yet clear. Herein, we aimed to explore the mediating effect of depression between sleep quality and STM in older adults and further test the gender differences in this relationship.
Methods
A cluster sampling survey was carried out among 903 residents that were aged 60+ years in a semi‐closed island of Xiamen, China, in 2019. The subjects' sleep quality … Show more
“…Disease-related characteristics included number of comorbidities, blood pressure, duration of hypertension, blood pressure control, and number and type of antihypertensive medications. Health-related characteristics included body mass index (BMI), sleep quality, and depressive symptoms that may confound memory (Wang & Chen, 2012; Yuan et al, 2021).…”
Background:Hypertension is prevalent in older women and is associated with increased cognitive impairment. Exercise has demonstrated beneficial effects on cognitive function, but the impact of exercise on older hypertensive women remains unclear. We investigated the effects of an aerobic walking program on memory, subjective cognitive complaints, and brain-derived neurotrophic factor in older hypertensive women. Methods: A quasi-experimental study with a pretest–posttest design was conducted. Older hypertensive women were randomly assigned to the aerobic walking group or a control group with routine care. The intervention group received a 24-week aerobic walking program. Data were collected at baseline and 24 weeks after enrollment. Participants’ characteristics, memory, subjective cognitive complaints, and plasma brain-derived neurotrophic factor were analyzed. Results: The aerobic walking group ( n = 30) reported improvements in total recall, delayed recall, and subjective cognitive impairment after 24 weeks of aerobic walking. Compared to the control group ( n = 28), the aerobic walking group showed significantly greater improvement in delayed recall at 24 weeks. However, aerobic walking had no significant effect on subjective cognitive complaints or brain-derived neurotrophic factor. Conclusion: The aerobic walking training significantly improved memory performance among older women with hypertension. A longer randomized controlled trial with a larger sample is necessary to confirm and further explore the effects of this intervention.
