Association between dietary fatty acid patterns and obesity indices in Jordanian adults: A cross-sectional study

Background: The ratios of fatty acids in different diets and their connection to chronic diseases including obesity and CVD have been researched. The current study set out to detect the dietary fatty acid patterns among Jordanian adults and their relationships with obesity indices. Methods: The data of 1096 adults were extracted from a household food consumption patterns survey study. Food intake was analyzed, and fatty acid patterns were determined. After anthropometric measurements, obesity indices were calculated. Results: Two fatty acid patterns were determined (High fatty acids from Protein and Olive Oil sources pattern, and the low Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) pattern), explaining an overall variance of 41.78% and 24.31%, respectively. A significant difference in obesity scores through fatty acids pattern quartiles was only seen among female participants. Q4 of the "High fatty acids from Protein and Olive Oil sources" pattern had a significantly higher means of body mass index (25.12 & PLUSMN; 0.46; p = 0.015), waist-to-height-ratio (0.51 & PLUSMN; 0.01; p = 0.002), weight-adjusted waist index (10.13 & PLUSMN; 0.09; p = 0.021) and body roundness index (3.61 & PLUSMN; 0.15; p = 0.007) compared to Q1, while Q4 of "Low EPA and DHA" pattern had significantly higher means of waist circumference (WC) (86.28 & PLUSMN; 1.34) and a body shape index (ABSI) (10.12 & PLUSMN; 0.30) in comparison to Q1 (WC = 81.55 & PLUSMN; 1.08 and ABSI = 9.07 & PLUSMN; 0.22; p = 0.025, 0.013; respectively). In females, there was a significant association between the "High fatty acids from Protein and Olive Oil sources" pattern and all the obesity indices. Conclusion: Our results suggest that an increase in the high fatty acids from Protein and Olive Oil sources pattern is associated with a reduction in obesity indices, which is opposite to the low EPA and DHA pattern. This was a sex-specific association.
