Effect of omega-3 polyunsaturated fatty acid on endometriosis
Abstract
Objective: This study aimed to evaluate the effect of Omega-3 Fatty Acids (ω-3 PUFAs) on endometriosis.
Design: The authors conducted a comprehensive search of the PubMed, Embase, Cochrane Library and Web of Science databases, focusing exclusively on Randomised Controlled Trials (RCTs) to study the impact of ω-3 PUFAs on endometriosis. The included studies were assessed for methodological quality using the Cochrane bias risk assessment tool and analyzed using data analysis software.
Results: The search yielded five RCTs conducted between the database's inception and July 2023, with a total sample size of 424 patients with endometriosis. The meta-analysis results showed no statistically significant effects of ω-3 Polyunsaturated Fatty Acids (PUFAs) on pain (Mean Difference [MD = -0.387], 95 % Confidence Interval [95 % CI -1.742-0.967], I2 = 93.3 %, z = 0.56, p = 0.575), sexual activity (MD = 0.143, 95 % CI -0.210-0.497, I2 = 0 %, z = 0.79, p = 0.427), pain intervention (MD = -0.216, 95 % CI -0.717-0.285, I2 = 0.0 %, z = 0.84, p = 0.399), catastrophic thinking (MD = 0.158, 95 % CI -0.315-0.632, I2 = 0.0 %, z = 0.66, p = 0.512) and the 12-item short form health survey (MD = 0.001, 95 % CI -0.053-0.503, I2 = 0.0 %, z = 0.00, p = 1.000), which were all statistically insignificant. However, ω-3 PUFAs appeared to reduce the inflammatory response in patients with endometriosis (MD = -5.20, 95 % CI -6.21--4.20, I2 = 0 %, z = 10.13, p < 0.001).
Conclusion: Based on the available…
