| خلاصه مقاله | Background: Osteoarthritis (OA) is a progressive rheumatic disease whose incidence is growing continuously with the aging population. The aim of this study was to assess the correlation between dietary intake of micronutrients and clinical symptoms in women with knee osteoarthritis in Tabriz.
Methods: A total of 70 knee OA women (mean age: 52.05±6.13 years) were recruited from the rheumatology clinic of Tabriz University of Medical Sciences. Dietary intake was evaluated using a 24-hour recall method for 3 days (including 2 working days and 1 weekend). Clinical symptoms were assessed using the WOMAC Osteoarthritis Index. Correlations between variables were analyzed by Pearson correlation analysis.
Results: The mean±SD WOMAC pain, stiffness, physical function and total score were 9.86±4.34, 2.85±1.48, 31.53±10.25 and 44.26±14.41, respectively. Dietary calcium intake correlated significantly with WOMAC pain (r=-0.290, P=0.016) and total score (r=-0.233, P=0.04). Furthermore, there were significant correlations between dietary magnesium (r=-0.238, P=0.040; r=-0.263, P=0.029; r=-0.276, P=0.021) and selenium intake (r=-0.253, P=0.036; r=-0.261, P=0.030; r=-0.275, P=0.022) with WOMAC pain, function and total score. No significant correlation was found between dietary zinc, phosphorous, manganese and vitamin intake with clinical symptoms.
Conclusion: The findings of this cross-sectional study indicate that calcium, magnesium, and selenium intake are inversely correlated with knee OA. It supports potential role of these micronutrients in the prevention of knee OA. |
