Summary: Introduction: Depression represents a public health problem due to the high
prevalence and incidence in recent years in the general population and
especially in the rural population. The deficiency of micronutrient selenium,
has an impact on mental health contributing to the development of the most
serious and common depressive disorder, the major depressive disorder.
Objective: This study aims to evaluate the consumption of selenium and its
association with depressive symptoms in farmers in southeastern Brazil.
Methodology: Cross-sectional epidemiological study carried out with 736
farmers in the municipality of Santa Maria de Jetibá / ES. Data collection
took place from December 2016 to April 2017. A semi-structured questionnaire
was used to collect sociodemographic data, lifestyle and clinical condition.
Data on food consumption were collected through the application of three
24-hour recalls. Depressive episodes were identified using the
Mini-International Neuropsychiatric Interview instrument. Results: 16.1% (n =
119) of farmers showed symptoms of a major depressive episode, with 5.8% (n =
43) being a current depressive episode and 10.3% (n = 76) a recurring major
depressive episode. Sociodemographic factors associated with depression were
sex (p <0.001), marital status (p = 0.004) and socioeconomic class (p =
0.015). Regarding the lifestyle and clinical condition factors, there was a
significant association between depression and alcohol consumption (p =
0.002), pesticide poisoning (p = 0.001) and selenium consumption (p = 0.032).
There was no significant association with the variable smoking. The lower
consumption of selenium was associated with the occurrence of depression even after adjustments for the sociodemographic variables, lifestyle and pesticide poisoning (OR = 2.17; 95% CI = 1.11 -1 4.24). Conclusion: Inadequate selenium consumption is a risk factor for depression. The findings of this study will contribute to the limited literature on mental health in rural workers, strengthening the evidence of the influence of nutrients, such as selenium, on the development of depression.
