Title : Knowledge, attitudes and practices in students of the health area in an ecuadorian university and its association to the serological profile for hepatitis b by immunization
Viral hepatitis is a global public health problem according to the World Health Organization, comparable to other communicable diseases of importance such as human immunodeficiency virus (HIV), tuberculosis and malaria. Hepatitis B virus (HBV) causes an infectious and contagious disease presenting in acute and chronic form. In Ecuador the three dose vaccination scheme is applied. The objective of the research was to evaluate the knowledge, attitudes and practices of students in the health area and their association with the serological profile for hepatitis B generated by immunization in an Ecuadorian university. The study design used was descriptive, explanatory, prospective, cross-sectional. The sample was of 183 students enrolled, of which 88 corresponded to the basic cycle and 95 to the professional cycle of the race, in whose sera anti-surface antigen antibodies of the Hepatitis B virus (anti HBs) were determined by the method of ELISA The results showed that 80.32% of the samples were seropositive to anti HBs antibodies. 37.15% have applied a single dose, 20.76% have received their second dose and only 14.75% applied the third dose of the three dose vaccine schedule. To determine the level of knowledge, attitudes and practices in the students, a validated survey was applied, where only 42.11% showed a satisfactory level, while a large percentage of the students in the health area considered a risk group are unaware of the mode of transmission, risk factors and prevention measures. The most sensitive group were the students of the basic cycle. Of the population analyzed that reported a vaccination history, 16% did not show seropositivity to anti-HBs antibodies, so they are considered non-responders, not observing a statistical association between the positivity of antibodies and the vaccination history.
