To compare cognitive function among frail and prefrail older adults.

Cross-sectional clinical study.

Fifty-one non-institutionalized older individuals participated in this study.

Cognitive functions were evaluated through Mini-Mental State Examination (Global Cognition), Digit Span Forward (short-term memory), Digit Span Backward (working memory), Verbal Fluency Test (semantic memory/executive function). Data were compared using parametric and non-parametric bivariate tests. Binary logistic regression was used to test a frailty prediction model. Statistical significance was defined as p ≤ 0.01 to compare groups. In the regression model, the p value was set to be ≤0.05.

Statistically significant differences were observed in global cognition, and short-term memory between frail and prefrail individuals (p ≤ 0.01). Global cognition explained 14–19% of frailty's model.

According to our findings, the evaluation of cognitive functions among older persons with frailty and prefrailty provides important complementary information to better manage frailty and its progression.

To assess the association between physical intimate partner violence and household food security within households with schoolchildren.

Cross-sectional study.

Salvador, Bahia, north-eastern Brazil.

The study was conducted in 1019 households with students. Violence between couples was evaluated using the Portuguese version of the revised Conflict Tactics Scales (CTS2), previously adapted and validated for use in Brazil. The Brazilian Food Insecurity Scale (BFIS) was used to identify food insecurity. We also obtained socio-economic information for each participant. We used multivariate Poisson regression to assess the associations of interest.

According to the results of the BFIS, 62·5 % of the households were found to experience food insecurity, including 19·5 % moderate food insecurity and 6·5 % severe food insecurity. The prevalence of minor physical violence was 9·6 % (95 % CI 7·8, 11·4 %) and of severe physical violence was 4·7 % (95 % CI 3·4, 6·0 %) among the couples. In the final multivariate model, it was found that couples reporting minor (prevalence ratio=1·23; 95 % CI 1·12, 1·35) and severe (prevalence ratio=1·16; 95 % CI 1·00, 1·34) physical violence were more likely to be experiencing household food insecurity, compared with those not reporting physical violence.

Physical intimate partner violence was associated with food insecurity of households. The present study brings new data to the subject of the role of violence in the context of food insecurity.
