Abstract

Background and aims: Substantial evidence have linked low grade inflammation with the pathophysiology of chronic diseases and psychological impairment. An integral component underlying the link is pro-inflammatory diet. While sleeping is another significant contributor, few studies have addressed the relationship between the sleep quality and inflammatory cascade with the dietary quality as a moderator. The current study assesses the relation between inflammatory potential of the diet and sleep quality in Iranian obese and overweight women. Method: A total of 219 obese and overweight adult women were enrolled in this cross-sectional study. A standard 147-item food-frequency-questionnaire was used to record the dietary intakes; then, the dietary inflammatosry index (DII) was derived from the result-consolidated questionnaires. Pittsburgh Sleep Quality Index (PSQI) was utilized to withdraw the sleep quality and quantity. Results: The mean (±standard deviation) age, body mass index, and PSQI of individuals were 36.49 (8.38) years, 31.04 (4.31) kg/m2 , and 5.78(3.55), respectively. Patients in the highest DII quartile were the ones with the higher consumption of pro-inflammatory food, and, ∼ 58% of participants who were in the higher quartile had a sleep disturbance status. Results revealed an inverse relationship between sleep quality and DII in the crude model (β = 0.17, p=0.01) as well as full-adjusted model (β=0.24, p < 0.001), such that women with higher DII had the poorest sleep quality. Conclusion: Based on the present observational study, obese and overweight females with higher adherence of the anti-inflammatory diet may have better sleeping status. © 2021 Hogrefe.
