Background We hypothesized that insufficient intake of fish oil–derived omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs) during pregnancy is a contributing factor to gastroenteritis in early childhood. We examined the effect of n-3 LCPUFA supplementation on gastroenteritis symptoms in the offspring's first 3 years of life. Methods This was a double-blinded, randomized controlled trial whereby 736 mothers were administered n-3 LCPUFA or control from pregnancy week 24 until 1 week after birth. We measured the number of days with gastroenteritis, number of episodes with gastroenteritis, and the risk of having a gastroenteritis episode in the first 3 years of life. Results A median reduction of 2.5 days with gastroenteritis (P  = .018) was shown, corresponding to a 14% reduction in the n-3 LCPUFA group compared with controls in the first 3 years of life (P  = .037). A reduction in the number of gastroenteritis episodes (P  = .027) and a reduced risk of having an episode (hazard ratio, 0.80 [95% confidence interval,.66–.97]; P  = .023) were also shown. Conclusions Fish oil supplementation from the 24th week of pregnancy led to a reduction in the number of days and episodes with gastroenteritis symptoms in the first 3 years of life. The findings suggest n-3 LCPUFA supplementation as a preventive measure against gastrointestinal infections in early childhood. Clinical Trials Registration NCT00798226. [ABSTRACT FROM AUTHOR]
