Parallel Assessment Challenges in Nutritional and Sleep Epidemiology

Sleep has been consistently linked to health outcomes in clinical studies, but only in recent years has sleep become a focus in epidemiologic studies and public health. In particular, the sizable prevalence of insufficient sleep in the population warrants well-designed epidemiologic studies to examine its impact on public health. As a developing field, sleep epidemiology encounters methodological challenges similar to those faced by nutritional epidemiology research. In this article, we describe a few central challenges related to assessment of sleep duration in population-based studies in comparison with measurement challenges in nutritional epidemiology. In addition, we highlight 3 strategies applied in nutritional epidemiology to address measurement challenges and suggest ways these strategies could be implemented in large-scale sleep investigations.

Automated summary

Sleep has significant impact on public health, and sleep epidemiology faces challenges similar to nutritional epidemiology research. Strategies used in combating measurement challenges in nutritional epidemiology may also be applicable in large-scale sleep investigations.
