5. Conclusions
In conclusion, nutrition group activities in community centers are likely to promote healthy eating in elders, which may in turn regress their frailty status and improve their working memory. The effect of this group-level intervention is comparable to or better than that of the individual-level ones, while the manpower used is much less. We found that physical functional changes were accompanied by changes in dietary intake. However, the improved frailty status backslid after the intervention ceased, suggesting that boosting activities or maintenance mechanisms might be needed to prevent waning of the intervention effect.
