Objective: The effect of dietary proteins on sleep is uncertain.Meat is of special interest because it provides high-quality protein as well as saturated and trans fatty acids. Furthermore, it is the main source of dietary protein in many countries. However, the effect of meat intake on sleep patterns is unclear.The aim of this study was to examine the association of habitual meat consumption with changes in sleep duration and with sleep quality in older adults.
Methods: We used data from 1,341 participants in the Seniors-ENRICA cohort aged ≥60 years, followed from 2012 through 2015. Habitual meat consumption was assessed at baseline with a validated diet history. Sleep duration and quality were ascertained both in 2012 and 2015. Analyses were performed with logistic regression and adjusted for socio-demographic variables, lifestyle, morbidity, sleep duration and poor sleep indicators at baseline.
Results: During follow-up, 9.0% of individuals increased and 7.9% decreased their sleep duration by ≥2 hours/night. Compared with individuals in the lowest tertile of meat consumption, those in the highest tertile showed increased incidence of a large decrease (≥2 h) in sleep duration (OR: 1.93; 95% CI:1.01-3.72; p-trend:0.04). Higher consumption of meat was also associated with incidence of snoring (OR:2.06; 95% CI:1.17-3.60; p-trend:0.01) and poor general sleep quality (OR:1.71; 95% CI:1.04-2.82; p-trend:0.03). Each 100 g/d increment in meat intake was associated with a 60% higher risk of both large sleep duration changes and poor sleep quality (OR:1.60; 95% CI:1.07-2.40). Results were in the same direction for red and processed meat and for white meat separately, and among individuals with physical impairment.
Conclusion: Highermeat consumption was associated with changes in sleep duration and with poor sleep in older adults.
