Resumo
Introduction: Depression and deficiency in the consumption of micronutrients are a
public health problem, especially in the rural population. The deficiency in selenium
consumption affects mental health, contributing to the development of major depressive
disorders. Thus, this study aimed to evaluate selenium intake and its association with
depressive symptoms in farmers in southeastern Brazil.
Material and Methods: Epidemiological, cross-sectional, and analytical study with
736 farmers aged between 18 and 59. A semistructured questionnaire was used to
collect sociodemographic, lifestyle and clinical condition data. For evaluation of food
intake, three 24-h recalls were applied, and for identification of depressive episodes,
the Mini-International Neuropsychiatric Interview was conducted.
Results: A total of 16.1% (n = 119) of the farmers presented symptoms of major
depressive episodes, 5.8% (n = 43) presented symptoms of current depressive
episodes, and 10.3% (n = 76) presented symptoms of recurrent major depressive
episodes. Sociodemographic factors associated with depression were gender (p <
0.001), marital status (p = 0.004), and socioeconomic class (p = 0.015). The
consumption of high doses of selenium was associated with a reduction of ∼54% in
the chances of occurrence of depression (OR = 0.461; 95% CI = 0.236–0.901).
Conclusion: High selenium intake is associated with a lower prevalence of depression
even after adjusting for sociodemographic variables, lifestyle, and pesticide intoxication.
The findings of this study contributed to highlighting the high prevalence of depression
in rural areas and its relationship with selenium intake.
