Introduction:

Depression affects more than 300 million people in the world, it is the leading cause of disability and contributes significantly to the global burden of disease. Objective: To determine the prevalence and some social, personal, and family factors associated with major depressive disorder in a population aged from 15 to 65 in Envigado (Colombia) in 2017.

Methods:

A cross-sectional study with analytical intent was conducted, based on the information from 905 participants for the “Population study of mental health 2017”, collected through interviews administered by means of the World Health Organization Composite International Diagnostic Interview -CIDI-OMS. The processing was performed using the SPSS program version 23. (CES University License).

Results:

Four factors correlate with major depression in the last year in the study population: drug abuse other than alcohol (ORaj = 4,43 [1,164-16,833]), a close relative´s death or illness (ORaj = 4,15 [1,583-10,880]), high resilience (ORaj = 0.22 [0,112-0,425]) and an excellent or good mental health perception (ORaj = 0.19 [0.098-0.378]).

Conclusions:

the factors that increase the probability of major depression in the study population are drug abuse other than alcohol and the death or illness of a first-degree relative; and the protective factors are high levels of resilience and an excellent or good perception of one's own mental health. This evidence reinforces the need to implement promotion programs focused on improvement of life skills, which provide adequate strategies to face the challenges.
