Introduction:

In Medellin, the magnitude of various sexually transmitted diseases is unknown based on population studies.

Objective:

To determine frequency of VDRL reactivity and positivity for Chlamydia spp. HIV, Hepatitis B virus (HBV) and Hepatitis C Virus (HCV) in an institution health of Medellin, 2015.

Methods:

a cross-sectional study was done in all people screened for VDRL (N = 10 288), Chlamydia spp. (N = 349), HIV (N = 5 386), Hepatitis B Virus (N = 3369) and Hepatitis C Virus (N = 1450). Clinical laboratory records were used, the bias control was realized through verification for ranges and reproducibility in data extraction. Tests with sensitivity and specificity greater than 95 % were used. The frequency of each agent was estimated and its association with sex and age groups were explored using Fisher and chi-square.

Results:

The age range was 0-98 years, with a higher proportion of women. The frequency of Chlamydia spp. was 3.4 % (95% CI = 1.4- 5.4), reactive VDRL 2.7% (95% CI = 2.4-3.0), Hepatitis B Virus 1.7% (95% CI = 1.2-2.1), Hepatitis C Virus 0.6% (IC95 = 0.1-1.0) and HIV 0.2% (95% CI = 0.1-0.3). The occurrence of reactive VDRL, HIV and HBV was statistically higher in men compared with the women. The age group presented association with reactive VDRL, HIV and Hepatitis B and C Virus. Reactive VDRL was higher in children and viral infections in patients over 40 years.

Conclusion:

The overall frequency was similar to that reported in other populations, except for Chlamydia spp., which it was lower in the current study; meanwhile, the specific frequencies show differences in the distribution of agents by sex and age group, allowing the identification of the groups with major occurrence, for orientation of further studies and preventive measures in specific groups.
