They are within the age range of 14-40 years with mean (± SD) age of 24.7 (± 6.3). The women attend antenatal clinic at the State Specialist Hospital, a secondary health facility in Maiduguri, Borno state. The women are all heterosexuals. The distribution of HBsAg carrier rate according to age of women studied showed a significant (p = 0.0061) increase of the prevalence of HBsAg from 4 (8.7%) in the lower age group (39 years). According to the number of pregnancies, the prevalence of HBsAg infection increased significantly from 6 (9.2%) among primiparous to 13 (13.7%) and 14 (38.9%) among multiparous and grand multiparous respectively. The carrier rate of HBsAg infection among the pregnant women studied based on their duration of pregnancies and their social class showed no significant differences. However, according to the factors known to be commonly associated with the highest risk of transmission of HBV such as history of blood transfusion, Tribal marks/tattooing, use of sharps, sharing of articles, history of jaundice in the women and husbands, history of sexually transmitted infections (STIs) of the women and husbands and the type of marriage (monogamous or polygamous), number of sexual relationships per week, only the history of blood transfusion was significantly associated with HBsAg carrier rate (RR = 3.71., 95% Confidence Interval (C.I.), 1.89-7.30, p = 0.0078). The study confirms that pregnant women who attend antenatal clinic in this secondary health facility are at higher risk of being infected with the HBV, which could lead to both prenatal and post natal transmission to their newborns.展开更多
