Objective: The aim of this study was to analyze dietary ω-6:ω-3 polyunsaturated fatty acid (PUFA) ratio and its association with adiposity and serum adiponectin levels in a Mexican population. Methods: In this cross-sectional study, individuals with a BMI ≥ 18.5 kg/m2, were classified using four methods to measure adiposity. Parameters of body composition were measured by InBody 3.0. Diet intake was evaluated prospectively using a 3-day written food record. Serum high-molecular weight adiponectin isoform was measured using an ELISA assay. Biochemical and adiposity variables were analyzed by tertiles of dietary ω-6:ω-3 PUFA ratio. Results: A total of 170 subjects were recruited with a mean age of 36.9 ± 11.8 years. The 73.5% of subjects were women. Subjects in the higher tertile of dietary ω-6:ω-3 PUFA ratio had more adiposity and higher levels of triglycerides, VLDL-c, glucose, insulin and HOMA-IR than those in the first tertile (p Conclusion: This study suggests that high dietary ω-6:ω-3 PUFA ratio is positively associated with excessive adiposity and worse metabolic profile.
