Gender differentiated score on the Falls Efficacy Scale International (FES-I Brazil) to assess self-efficacy in falls in community-dwelling older adults

Self-efficacy as a mediator between frailty and falls among community-dwelling older citizens

Frailty is one of the most challenging issues among older adults, and the relationship between frailty and falls has already been assessed numerous times in literature. In the present study, we explored the mediating role of self-efficacy related to falls (FSe) in the relationship between frailty and fall risk. In a cross-sectional design, 1080 community-dwelling older adults from Rotterdam (Netherlands) and Valencia (Spain) completed a questionnaire and data were then analyzed via mediation analysis using a bootstrapping approach. Results show that higher frailty is associated with higher fall incidence, and higher FSe is a partial mediator of this association, with a confidence interval for the indirect effect of 0.131-0.247. Moreover, results showed gender differences in FSe levels; women had lower FSe scores. Deepening research on the construct of FSe may give potential explanations that account for the emerged gender differences, and it could be more targeted in fall prevention programs.

How much time of sedentary behavior is associated with depressive symptoms in community-dwelling older adults in southern Brazil?

AIMS

Identify sedentary behavior (SB) cut-off points to screen for depressive symptoms in older adults and verify the association between these conditions.

METHODS

A cross-sectional survey of 308 community-dwelling older adults was conducted. The outcome was the presence of depressive symptoms (≥6 points on the Geriatric Depression Scale-15). The exposure was SB using the self-reported time on a weekday and weekend (International Physical Activity Questionnaire). The cut-off points for SB categorization were determined by the receiver operating characteristic curve and multivariate logistic regression to verify the association.

RESULTS

Older adults who spent ≥4.5 hours/day in SB (sensitivity = 48.8%; specificity = 67.8%) were 1.81 times more likely (95%CI: 1.03;3.15) to have depressive symptoms compared to those who stayed for shorter periods.

CONCLUSIONS

There was an association between SB and depressive symptoms; therefore, older adults must have SB <4.5 hours/day to reduce the chances of developing depressive symptoms.
