Dietary Inflammatory Index of Obese Individuals with Obstructive Sleep Apnea: A Descriptive Study

Area of Science:

• Nutrition Science
• Sleep Medicine
• Obesity Research

Background:

• Obesity and obstructive sleep apnea (OSA) are significant health concerns.
• Dietary patterns can influence inflammation and metabolic health.
• The relationship between dietary inflammatory potential and sleep in OSA patients requires further investigation.

Purpose of the Study:

• To characterize the dietary inflammatory profile in obese individuals with OSA.
• To examine correlations between the dietary inflammatory index (DII) and sleep parameters.
• To assess the association between dietary intake and metabolic/hormonal profiles.

Main Methods:

• Nocturnal polysomnography was conducted on 40 obese individuals with OSA.
• Anthropometric, body composition, and blood lipid/glycemic/hormonal profiles were assessed.
• Dietary intake was evaluated using 3-day food records to calculate the DII.

Main Results:

• A predominantly proinflammatory dietary profile was observed.
• Participants exhibited low intake of fruits, vegetables, fiber, magnesium, vitamin D, and vitamin E.
• No significant correlation was found between the dietary inflammatory profile and OSA severity.

Conclusions:

• The study identified a proinflammatory dietary pattern in obese individuals with OSA.
• Despite no direct link to OSA, improved dietary patterns correlated with better sleep quality.
• This highlights the importance of nutritional interventions for sleep health in this population.
