Abstract Objective: To verify the association between c.1083T>C polymorphism in the adenosine receptor A2A gene (ADORA2A) and objective sleep, as well as the correlation between caffeine consumption, sleep parameters, and electroencephalographic spectral power in a large, population-based sample from Sao Paulo, Brazil. Methods: This study was conducted in participants of the Sao Paulo Epidemiologic Sleep Study (EPISONO), a large, population-based survey consisting of a representative sample of the inhabitants of the city from Sao Paulo, Brazil, according to sex, age (20-80 years), and socioeconomic status in the year 2007. Questionnaires, polysomnography, spectral analysis of sleep electroencephalogram, and c.1083T>C polymorphism genotyping were performed in this study. Results: We found that caffeine consumption was positively correlated with sleep latency and a spectral power, as well as negatively correlated with percentage of N3 stage and delta spectral power in this stage. However, this association was identified only in T allele carriers and not in CC genotype. Conclusion: Our data support an important aspect of this polymorphism in ADORA2A gene, showing that the variant affects the association between caffeine consumption and objective sleep parameters in a large population-based cohort.
