Publication Abstract: 

The aim of the study was to understand whether dietary fatty acids such as saturated, polyunsaturated, and monounsaturated fatty acids act as inflammatory mediators or influence pro-coagulation in Saudi adults. The study sought to examine inflammatory factors such as C-reactive protein, tumor necrosis factor-alpha and activated plasminogen activator inhibitor 1. A total number of 232 consenting Saudi adults, aged 18-60 years were randomly selected in this cross-sectional study. Independent Student t-test was done to compare means of normally distributed data. Spearman correlation between the variables was determined. The values of different fatty acids and adipokines were transformed logarithmically/square root to normalize data before correlations were determined and statistical analyses performed. Statistical significance was set at p<0.05. The results show a significant positive correlation of dietary intake of poly and monounsaturated fatty acids, but not saturated fatty acids, with activated plasminogen activator inhibitor 1 (r=0.31, p=0.02, r=0.32 p=0.04). On the other hand, dietary intake of saturated fatty acids showed a negative correlation with serum C-reactive protein levels (p=0.001) in males. Dietary unsaturated fatty acids is possibly associated with the production of a pro-coagulation factor without enhancing the secretion of pro-inflammatory molecules, while saturated fatty acids have no effect on activated plasminogen activator inhibitor 1, but their level is negatively associated with the inflammatory factor C-reactive protein. We conclude that dietary intake may exert a gender-specific effect in inflammatory processes among adults. Further studies are warranted to confirm present findings.
