- Cognitive predictors of limited health literacy in adults with heterogeneous socioeconomic backgrounds(2015) APOLINARIO, Daniel; MANSUR, Leticia L.; CARTHERY-GOULART, Maria T.; BRUCKI, Sonia M. D.; NITRINI, RicardoThe purpose of this study was to explore the relationship between health literacy and specific cognitive abilities in hospital users. A neuropsychological battery was administered and the Short Test of Functional Health Literacy in Adults was used to classify individuals as having adequate or limited functional health literacy. Of the 322 participants, 102 (31.7%) presented limited health literacy. Even after adjusting for demographics, years of education, and quality of education, health literacy was strongly associated with measures of cognitive performance, but the strength of association was variable across different cognitive abilities.
- Environmental heat exposure and cognitive performance in older adults: a controlled trial(2015) TREZZA, Beatriz Maria; APOLINARIO, Daniel; OLIVEIRA, Rafaela Sanchez de; BUSSE, Alexandre Leopold; GONCALVES, Fabio Luiz Teixeira; SALDIVA, Paulo Hilario Nascimento; JACOB-FILHO, WilsonThermal stress has a negative effect on the cognitive performance of military personnel and industry workers exposed to extreme environments. However, no studies have investigated the effects of environmental thermal stress on the cognitive functions of older adults. We carried out a controlled trial with 68 healthy older adults (mean age 73.3 years, 69 % female), each of whom has been assessed twice on the same day with selected tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Repeated sessions were conducted with air temperatures set at 24 degrees C and 32 degrees C in a balanced order. Our primary analyses did not show significant differences when comparing the cognitive performance of the total sample under the two experimental temperatures. However, interaction analysis has shown that humidity levels modify the effect of temperature on cognitive outcomes. The subgroup exposed to relative humidity greater than themedian value (57.8%) presented worse cognitive performance in the heat session when compared to the control session. Reported exercising frequency explained individual vulnerability to heat stress. Volunteers with lower levels of physical activity (< 4 times per week) were more likely to present worsened cognitive performance under heat stress. In a fully adjusted linear regression model, the performance under heat stress remained associated with relative humidity (beta=-0.21; p=0.007) and frequency of exercising (beta=0.18; p=0.020). Our results indicate that heat stress may have detrimental effects on the cognitive functioning of some subgroups of older adults and under particular circumstances. Further research is needed for exploring a variety of potentially influential factors.
