- Abstract
- (1) Background: Omega-3 fatty acids (omega 3FAs) are known to improve protein anabolism, increase the sensitivity to anabolic stimuli, decrease lipogenesis, and stimulate lipid oxidation. We aim to investigate whether omega 3FAs are associated with the prevalence of sarcopenic obesity (SO). (2) Methods: Data were obtained from the 2014-2018 Korean National Health and Nutrition Examination Survey. The ratio of daily omega 3FA intake to energy intake (omega 3FA ratio) was categorized into four quartile groups. (3) Results: The prevalence of SO from Q1 to Q4 was 8.9%, 11.3%, 11.0%, and 9.8% respectively, in men and 17.4%, 14.0%, 13.9%, and 10.1% respectively, in women. The omega 3FA ratio in individuals with and without SO were 1.0% and 0.9% in men (p-value = 0.271) respectively, and 0.8% and 1.0% in women (p-value = 0.017), respectively. Compared with Q1, odds ratios (95% confidence intervals) of Q2, Q3, and Q4 of omega 3FA ratios were 1.563 (0.802-3.047), 1.246 (0.611-2.542), and 0.924 (0.458-1.864) respectively, in men and 0.663 (0.379-1.160), 0.640 (0.372-1.102), and 0.246 (0.113-0.534) respectively, in women, after fully adjusting for confounding factors. (4) Conclusions: The omega 3FA ratio was significantly higher in older females without SO than in older females with SO. The omega 3FA ratio was associated with the prevalence of SO in elderly females.
