Studies from Columbia University in the Area of Depression Described [Omega-3 polyunsaturated fatty acid (PUFA) status in major depressive disorder with comorbid anxiety disorders]

By a News Reporter-Staff News Editor at Mental Health Weekly Digest -- Current study results on Mental Health have been published. According to news reporting from New York City, New York, by NewsRx journalists, research stated, "Although lower levels of omega-3 polyunsaturated fatty acids (PUFAs) are found in major depressive disorder, less is known about PUFA status and anxiety disorders. Medication-free participants with DSM-IV-defined major depressive disorder (MDD), with (n=18) and without (n=41) comorbid DSM-IV anxiety disorders, and healthy volunteers (n=62) were recruited from October 2006 to May 2010 for mood disorder studies at the New York State Psychiatric Institute."

The news correspondents obtained a quote from the research from Columbia University, "Participants were 18-73 years of age (mean age, 35.8 ± 12.6 years). Depression and anxiety severity was assessed using depression and anxiety subscales from the 17-item Hamilton Depression Rating Scale. Plasma PUFAs eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) and the ratio of arachidonic acid (AA; 22:4n-6) to EPA (AA:EPA) were quantified. This secondary analysis employed analysis of variance with a priori planned contrasts to test for diagnostic group differences in log-transformed PUFA levels (logDHA, logEPA, and logAA:EPA). Plasma levels of logDHA (F(2,118)=4.923, p=.009), logEPA (F(2,118)=6.442, p=.002), and logAA:EPA (F(2,118)=3.806, p=.025) differed across groups. Participants with MDD had lower logDHA (t(118)=2.324, p=.022) and logEPA (t(118)=3.175, p=.002) levels and higher logAA:EPA levels (t(118)=-2.099, p=.038) compared with healthy volunteers. Lower logDHA (t(118)=2.692, p=.008) and logEPA (t(118)=2.524, p=.013) levels and higher logAA:EPA levels (t(118)=-2.322, p=.022) distinguished anxious from nonanxious MDD. Depression severity was not associated with PUFA plasma levels; however, anxiety severity across the entire sample correlated negatively with logDHA (r(p)=-0.22, p=.015) and logEPA (r(p)=-0.25, p=.005) levels and positively with logAA:EPA levels (r(p)=0.18, p=.043). The presence and severity of comorbid anxiety were associated with the lowest EPA and DHA levels."

According to the news reporters, the research concluded: "Further studies are needed to elucidate whether omega-3 PUFA supplementation may preferentially alleviate MDD with more severe anxiety."
