“…In this regard, Guerra et al (46,47) evaluated risk factors associated with the probability of hospital admission and concluded that the lack of a social support network (as a consequence of the individual's marital status) and the housing distance from urban centers were factors associated with frailty. From the viewpoint of the peculiarities of Brazilian culture, this factor is important to be considered in studies of repeated hospital admission and frailty (48).…”

OBJECTIVE:Frailty syndrome can be defined as a state of vulnerability to stressors resulting from a decrease in functional reserve across multiple systems and compromising an individual's capacity to maintain homeostasis. The purpose of this study was to determine the prevalence of frailty and its association with social and demographic factors, functional capacity, cognitive status and self-reported comorbidities in a sample of community-dwelling older individuals who are clients of a healthcare plan.METHODS:We evaluated 847 individuals aged 65 years or older who lived in the northern area of the city of Rio de Janeiro, Brazil. The subjects were selected by inverse random sampling and stratified by gender and age. To diagnose frailty, we used the scale proposed by the Cardiovascular Health Study, which consisted of the following items: low gait speed, grip strength reduction, feeling of exhaustion, low physical activity and weight loss. The data were collected between 2009 and 2010, and the frailty prevalence was calculated as the proportion of individuals who scored positive for three or more of the five items listed above. To verify the association between frailty and risk factors, we applied a logistic regression analysis.RESULTS:The prevalence of frailty syndrome was 9.1% (95% confidence interval [CI], 7.3-11.3); 43.6% (95% CI, 40.3-47) of the individuals were considered robust, and 47.3% (95% CI 43.8-50.8) were considered pre-frail (p<0.001). The frail individuals tended to be older (odds ratio [OR] 13.2, 95% CI, 8.7-20) and have lower education levels (OR 2.1, 95% CI, 1-4.6), lower cognitive performance (OR 0.76, 95% CI, 0.73-0.79) and reduced health perception (OR 65.8, 95% CI, 39.1-110.8). Frail individuals also had a greater number of comorbidities (OR 6.6, 95% CI, 4.4-9.9) and worse functional capacity (OR 3.8, 95% CI, 2.9-5).CONCLUSION: The prevalence of frailty was similar to that seen in other international studies and was significantly associated with educational level, cognition, comorbidities, functional capacity, perception of health and old age.

“…Being male, living alone, and the existence of financial constraints in obtaining medications were associated with multiple hospital admissions 8 . Another study showed that the introduction of biomedical factors did not modify the above mentioned associations 6 . Another crosssectional study identified prior hospitalization, recent doctor visits, the presence of chronic disease (particularly diabetes and heart disease), sex, and age as associated with hospitalization among a private health maintenance organization in Brazil 10 .…”

“…7 More specifically, lower body-mass index and higher levels of serum cholesterol were associated with two or more hospital admissions. 8 The Bambuí Health and Aging Study and other population-based studies in our country will certainly bring us new knowledge regarding the challenges faced in managing public health and medical care in Brazil. …”
