Minors Mental Disorders (MDM) is a term created to describe symptoms such as insomnia, fatigue, irritability, forgetfulness, difficulty concentrating, and somatic complaints.

This study aimed to estimate the prevalence of MDM in São Francisco do Conde (SFC), Bahia.

We conducted a cross-sectional study by randomly selecting 456 individuals aged over 18 years, registered at the Family Health Program of CFS. The data were collected through home visits in the period from October to December 2010. The subjects answered a questionnaire containing the “Self-Report Questionnaire” (SRQ-20), the demographics and lifestyles. The SRQ-20 is composed of 20 questions, four about physical symptoms and sixteen on psycho emotional symptoms. The answers are “yes” or “no” and attributed, respectively, values of “1” and “0”. The cutoff suggested for identifying DPM was seven or more positive responses. The project was approved by a Research Ethics Committee registered the CONEP.

The results showed a prevalence of 37.7% of MDM. Among males the prevalence was 17.6% and in females was 47.5%, this result was statistically significant.

The results showed a high prevalence of psychological distress in this population, especially among females. The results stimulate the continuity of the actions of health surveillance carried out in the city.
