Investigation of hepatitis B virus infection status quo in different age groups of childbearing age women / 国际检验医学杂志

ABSTRACT

Objective To investigate the hepatitis B virus (HBV) infection status quo among childbearing age women to provide the theoretical basis for adopting the effective intervention ,treatment and blocking measures in pre-pregnant women .Methods The enzyme-linked immunosorbent assay (ELISA) and the time-resolved fluorometric immunoassay were adopted to detect HbsAg in 68 682 children bearing age women ,including outpatient and hospitalized patients ,in this hospital from February 2012 to September 2013 .The detect results were analyzed according to the age ,place of residence and medical departments .Results Among 68 682 children bearing age women ,3 260 cases were found positive for HbsAg with the HBsAg positive rate of 4 .70% .The statistically significant differences in the HBV infection positive rate existed among different age groups ,the positive rates in the age groups of 16- <20 years ,20 - < 25 years ,25 - < 30 years ,30 - < 35 years ,35 - < 40 years ,40 - < 45 years and 45 - < 50 years were 3 .83% ,4 .89% ,4 .96% ,4 .91% ,4 .18% ,4 .40% and 4 .18% respectively ,the differences among them had statistical significance (χ2 =15 .76 ,P=0 .015) ,in which the age 25- <30 years group had the highest HBV infection rate .At the same time the signifi-cant differences in the geographical distribution and medical departments existed .The HBV infection positive rate in rural area was significantly higher than that in city with statistical difference (χ2 =27 .47 ,P<0 .05) ,and the HBV infection positive rate in the outpatient departments was higher than that in the inpatient departments with statistical difference (χ2 =46 .88 ,P<0 .05) .Conclu-sion Children bearing women at 20-34 years old show the highest HBV infection rate .The HBV screening and the works of pre-vention and treatment during this age period should be strengthened ,which conduces to discover the HBV infection positive patients in time and prevent the mother-to-fetus transmission .
