Objective: To evaluate the effectiveness of an intervention program for preventing cognitive decline and improving quality of life among older adults in Da Nang City. Subjects and Methods: A community-based intervention study with a control group was conducted on 410 older adults (≥60 years old) living in Da Nang City from January 2025 to December 2025. Participants were divided into two groups: an intervention group (205 participants) and a control group (205 participants). Results: Before the intervention, there were no statistically significant differences between the two groups regarding age, gender, prevalence of cognitive decline, and quality of life scores (p > 0.05). After the intervention, the prevalence of cognitive decline in the intervention group decreased to 43.6%, which was lower than that in the control group (56.4%); however, the difference was not statistically significant (p = 0.208). The overall quality of life score in the intervention group (66.8 ± 10.3) was significantly higher than that in the control group (62.5 ± 11.1) (p < 0.001). The physical health and social relationship domains in the intervention group also showed significant improvement compared to the control group (p < 0.05). Conclusion: The preventive intervention program for cognitive decline showed a tendency to reduce the prevalence of cognitive decline and contributed to improving the quality of life of older adults in the community, particularly in the domains of physical health and social relationships.
