Hypothesis
The study aimed to identify distinct trajectories of frailty and cognitive function and examine the influence of sociodemographic and lifestyle factors on their co-development.
Conclusion
The study found significant heterogeneity in the co-development of frailty and cognitive function among older Koreans, influenced by various sociodemographic and lifestyle factors.
Supporting Evidence
- Three joint trajectories of cognitive frailty were identified: cognitive frailty (13.2%), cognitive decline and progressive frailty (33.0%), and no cognitive frailty (53.7%).
- Individuals in the cognitive frailty group were more likely to be unemployed and current smokers.
- Women, low-income individuals, and non-drinkers were more likely to be in the cognitive decline and progressive frailty group.
Takeaway
The study looked at how frailty and thinking skills change together in older people in Korea, finding that different life factors affect these changes.
Methodology
The study used group-based trajectory modeling and multinomial logistic regression to analyze data from the Korean Longitudinal Study of Aging.
Participant Demographics
Adults aged 65 years and older from South Korea.
