Mediterranean diet and changes in sleep duration and indicators of sleep quality in older adults
In this study by Campanini et al. (2017), the authors investigated the links between adherence to healthy dietary patterns, such as the Mediterranean diet (MD), and sleep duration and quality in a population of 1,596 older adults (volunteers of the seniors-ENRICA cohort, ≥ 60 years of age). Sleep duration (in hours) was recorded, and MD adherence was scored using the Mediterranean Diet Adherence Screener (MEDAS). Variables like lifestyle, morbidity, sleep duration, poor sleep indicators, and sociodemographics were taken into account. Follow-up duration approximated 2.8 years. Analysis of the results revealed that participants in the highest category of MD adherence demonstrated higher odds of increasing their sleep duration by ≥2 h/night and had lower odds of suffering from poor sleep (≥2 indicators of poor sleep quality), and changes in sleep quality, compared to participants in the lowest category of MD adherence. Thus, the authors conclude that MD fidelity results in a lower incidence of sleep changes and improvement in sleep quality in older adults.
