Abstract
SANCHZ-VILLEGAS and COLLEAGUES, School of Health Sciences, Department of Clinical Sciences, University of Las Palmas de Gran Canaria, Las Palmas, Spain. asanchez@dcc.ulpgc.es assessed the association between folate, vitamins B(6) and B(12) intake and depression prevalence in the SUN cohort study.
Background
An association between low blood levels of folate, vitamins B(6) and B(12) and a higher prevalence of depressive symptoms has been reported in several epidemiological studies. The present study aimed to assess the association between folate, vitamins B(6) and B(12) intake and depression prevalence in the SUN cohort study.
Methodology
The study comprised a cross-sectional analysis of 9670 participants. A validated semi-quantitative food frequency questionnaire was used to ascertain vitamin intake. The association between the baseline intake of folate, vitamins B(6) and B(12) categorised in quintiles and the prevalence of depression was assessed. The analyses were repeated after stratifying by smoking habits, alcohol intake, physical activity and personality traits.
Results
Among women, odds ratios (OR) [95% confidence interval (CI)] for the third to fifth quintile for vitamin B(12) intake were 0.58 (0.41-0.84), 0.56 (0.38-0.82) and 0.68 (0.45-1.04), respectively. Among those men with a low level of anxiety and current smokers, a significant positive association between low folate intake and the prevalence of depression was found. The OR (95% CI) for the first quintile of intake was 2.85 (1.49-5.45) and 2.18 (1.08-4.38), respectively, compared to the upper quintiles of intake (Q2-Q5) considered as a group.
Conclusion
Low folate intake was associated with depression among currently smoking men and men with low anxiety levels. Low intake of vitamin B(12) was associated with depression among women. No significant associations were found for vitamin B(6) intake.
