Chlamydia trachomatis IgG antibodies seroprevalence among students in two tertiary institutions in Anambra state, Nigeria: a comparative study
Chlamydia infection is a common sexually transmitted infection (STI) in humans caused by the bacterium Chlamydia trachomatis. This study assessed the seroprevalence of Chlamydia trachomatis antibodies among students in two tertiary institutions in Anambra State, Nigeria. It was a comparative cross-sectional survey using enzyme immunoassay kits for the determination of IgG class antibodies, while the multistage sampling technique was used in the selection of participants for the study. The overall prevalence of Chlamydia trachomatis antibodies observed in this survey was 14.3%, which was higher among students from the University (21.6%) than their counterparts from the College of Education (7.4%) (χ2=5.89, df=1p<0.015). Factors found to have significant effect on the seroprevalence of Chlamydia trachomatis in both institutions were: prior sexual exposure (p<0.05); unprotected sexual intercourse in the last one year (p<0.05); multiple sexual partners in the last one year (p<0.05); and presence of symptoms suggestive of STI (p<0.05). Among students in the College of Education, the place of residence significantly affected Chlamydia trachomatis seroprevalence with a preponderance towards students living off-campus (χ2=4.00, df-1, p<0.05). Hence, there is need to institute appropriate prevention and control measures against the transmission of the disease especially among those at risk of contracting the disease.
