Hypothesis
Does a multidomain lifestyle intervention improve dietary habits in older adults at risk for dementia?
Conclusion
The intervention improved participants' diets, particularly increasing fruit and vegetable consumption.
Supporting Evidence
- The intervention improved the healthy diet score significantly.
- Participants in the intervention group increased their fruit and vegetable consumption.
- Control group participants moved to initial stages of behavior change.
- Older adults at increased risk for dementia can benefit from lifestyle interventions.
- More tailored support may be needed to encourage diverse healthy eating.
Takeaway
This study shows that older adults can eat healthier by changing their lifestyle, especially by eating more fruits and vegetables.
Methodology
The study used secondary analyses of a cluster-randomized trial assessing dietary changes in older adults through a multidomain intervention.
Potential Biases
Self-reporting of food intake raises the risk of social desirability bias.
Limitations
The intervention's intensity varied among participants, and self-reported dietary data may introduce bias.
Participant Demographics
Participants were older adults (60-77 years) at increased risk for dementia, with a mean age of 69.0 years.
