Smear-Positive Tuberculosis Prevalence and Associated Factors among Pregnant Women Attending Antinatal Care in North Gondar Zone Hospitals, Ethiopia

Abstract EN

Tuberculosis is an ancient infectious disease that remains a threat to public health around the world.

It is a contagious airborne disease caused by Mycobacterium tuberculosis complex.

In high tuberculosis burden countries, the prevalence of tuberculosis was 10-fold higher in the HIV-infected mothers than that in those not infected with HIV.

However, little is known about the burden of tuberculosis (TB) and associated factors in women of reproductive age in most resource poor countries.

Therefore, this study aims to investigate prevalence of smear-positive TB and factors associated in pregnant women attending antenatal care in North West, Ethiopia.

An institution-based cross-sectional study was conducted in three governmental hospitals of the North Gondar Zone, and a total of 1272 pregnant women attending antenatal care were included.

Data were collected by trained personnel’s using a pretested and structured symptom screening questionnaire; then, spot-morning-spot sputum samples were collected from those pregnant women who had two or more weeks of cough, and sputum smear was done by using a light-emitted diode fluorescent microscope.

99% of the pregnant women visited the hospitals for antenatal care.

The prevalence of smear-positive tuberculosis was 864/100,000 population, and HIV positivity (AOR = 7.24; 95% CI: (2.01–26.03)), urban residence (AOR = 2.28; 95% CI: (1.419–3.158)), and family history of TB (AOR = 2.12; 95% CI: (1.371–3.451)) were significantly associated with smear-positive tuberculosis.

In this study, the prevalence of smear-positive tuberculosis was found to be higher than that in other community-based studies in the country.

Therefore, health education, targeted screening of pregnant women for TB, and collaboration of TB-HIV clinic with antenatal care clinic should be implemented in the area.

Further research should also be conducted for better understanding of the magnitude of tuberculosis in females of reproductive age.
