The effect of a 1-year multiple micronutrient or n-3 fatty acid fortified food intervention on morbidity in Indian school children.  Thomas et al., 2012 [217]  Children (6–10 years)RCT  α-linolenic acid (900 mg) + DHA (100 mg) vs. α-linolenic acid (140 mg)  Significantly fewer episodes of URTI/child/year (relative risk (RR) = 0.88, 95% confidence interval (CI): 0.79, 0.97) in high consuming n-3 fatty acids group.Significantly shorter duration/episode of URTI (RR = 0.81, 95% CI: 0.78, 0.85), LRTI (RR = 0.91, 95% CI: 0.85, 0.97) in high consuming n-3 fatty acids group.
