Reading Comprehension in Latin America: Difficulties and Possible Interventions

Fluency and reading comprehension as a performance indicator in the 3rd year of elementary school

PURPOSE

to verify whether fluency and reading comprehension vary throughout the third year of elementary school and can be used as performance indicators in reading.

METHODS

this is a prospective longitudinal study. 53 children participated in the study, regardless of gender. Four assessments were carried out throughout the year, using the LEPIC software to record the reading made by the children, recording reading errors, as well as the answers to questions regarding comprehension.

RESULTS

there was an evolution of reading fluency and literal comprehension throughout the tests, but not in inferential comprehension.

CONCLUSION

reading fluency and literal comprehension are good performance indicators in the third year of elementary school.

Risk factors for dementia in Brazil: Differences by region and race

INTRODUCTION

Twelve risk factors (RFs) account for 40% of dementia cases worldwide. However, most data for population attributable fractions (PAFs) are from high-income countries (HIC). We estimated how much these RFs account for dementia cases in Brazil, stratifying estimates by race and socioeconomic level.

METHODS

We calculated the prevalence and communalities of 12 RFs using 9412 Brazilian Longitudinal Study of Aging participants, then stratified according to self-reported race and country macro-regions.

RESULTS

The overall weighted PAF was 48.2%. Less education had the largest PAF (7.7%), followed by hypertension (7.6%), and hearing loss (6.8%). PAF was 49.0% and 54.0% in the richest and poorest regions, respectively. PAFs were similar among White and Black individuals (47.8% and 47.2%, respectively) but the importance of the main RF varied by race.

DISCUSSION

Brazil's potential for dementia prevention is higher than in HIC. Education, hypertension, and hearing loss should be priority targets.
