Dietary Patterns, n-3 Fatty Acids Intake from Seafood and High Levels of Anxiety Symptoms during Pregnancy: Findings from the Avon Longitudinal Study of Parents and ChildrenAuthors: Juliana dos Santos Vaz, et al. / Journal: PLOS One, July 2013
Excessive anxiety during pregnancy is associated with low birth weight, shorter length of gestation, and negative effects on infant brain development, including stress regulation. Among over 9,500 pregnant women in the UK, those with no intake of omega-3s from seafood had a 53% greater likelihood of high levels of anxiety when compared to pregnant women who got at least 1.5 grams omega-3s from seafood per week.
Suicide Deaths of Active-Duty U.S. Military and Omega-3 Fatty-Acid Status: A Case-Control ComparisonAuthors: Michael Lewis, et al. / Journal: The Journal of Clinical Psychiatry, August 2011
Suicides rival the battlefield in toll on the U.S. military. Researchers compared the omega-3 levels of 800 active-duty military personnel who died by suicide to levels among 800 controls. While all service members had low omega-3 levels, suicide death was 62% greater among men with the lowest DHA levels compared to those with the highest levels.
Depression during pregnancy is more common than post-partum depression and can negatively affect both moms and babies. Researchers studied over 14,000 women 32 weeks in to their pregnancy to determine if low seafood intake increases depression risk. Results show pregnant mothers who ate no seafood were about 50 percent more likely to have symptoms of depression than pregnant mothers who ate the most seafood (at least three servings of fish a week).
