Dietary habits may be associated with patients' biochemical characteristics.Aims and objectives To investigate whether frequency of food group consumption is associated with clinical characteristics of OSA patients.Methods 134 individuals (76.1% males, age: 49±10y) with polysomnography-diagnosed OSA were included in the analysis. Nutritional assessment was performed using a food frequency questionnaire and food group consumption (servings/day) was evaluated. Lipid levels, glucose metabolism indices (insulin, HOMA-IR) and inflammation markers (TNF-a and adiponectin) were measured, using appropriate assays in fasting blood samples.Results TNF-a levels were negatively correlated with whole grain and legume consumption (rho=-0,264, P=0,027 and rho=-0,321, P=0,007, respectively). In addition, a significant negative correlation was observed between adiponectin levels and red meat consumption (rho=-0,322, P=0,007). Finally, HOMA-IR index was positively correlated with refined grain, red meat and soft drink consumption (rho=0,212, P=0,040, rho=0,232, P=0,024, and rho=0,207, P=0,045, respectively). No association was found between fasting lipid levels and food group consumption.Conclusions Increased whole grain and legume consumption and reduced red meat consumption exhibit anti-inflammatory effects, whereas increased refined grain, red meat and soft drink consumption is associated with insulin resistance in OSA patients.
