RUEDA-SANCHEZ, Mauricio; DIAZ-MARTINEZ, Luis Alfonso and RUEDA-JAIMES, Germán Eduardo. Prevalence of Major Depressive Disorder and Related Factors: A Population Study in Bucaramanga (Colombia). rev.colomb.psiquiatr. [online]. 2008, vol.37, n.2, pp. 159-168. ISSN 0034-7450.
Objective: To estimate the prevalence of major depressive disorder and the association between depressive symptoms of clinical importance (DSCI) and known risk factors. Method: Cross-sectional study of 1,505 adults selected at random in Bucaramanga, Colombia. The survey included Zung's Self-rating Depression Scale, socio-demographic factors, life style factors, previous and current health conditions and vital stressor events in the last three months. DSCI was considered when the rating of the Zung's Depression Scale was =40 points. In order to adjust possible confusion factors a model of logistic regression was used, keeping in mind the effect of the sampling. Results: 328 subjects had DSCI (prevalence adjusted: 22.3%, CI95%: 20.0-24.6) corresponding with a Major Depressive Disorder prevalence of 11.2% (CI95%: 9.7-12.9%). No association was found among DSCI and age or coffee consumption, but the association was positive with being a woman, having a history of suicide intent or headache, having a relative with Daily Chronic Headache, suffering recent signifi cant losses and signifi cant family or work diffi culties, and was negative regarding educational level. Conclusion: The actual prevalence of Major Depressive Disorder in Bucaramanga is high and is associated with known risk factors such as female gender, educational level, previous suicide intent, recent psychosocial diffi culties and some physical symptoms like sleep problems, headache and Daily Chronic Headache.
