Prevalence, knowledge, sexual behaviour, and risk of transmission of hepatitis B virus amongst students of the University of Buea, Cameroon
Bibliographic record
Abstract
Hepatitis Binfection is a major health problem of public health importance. It istransmitted from person to person by contact with blood or other body fluidsfrom an infected person. Lack of or insufficient knowledge about HBV negatesthe global effort towards prevention of the infection. HBV and HIV share similar routes oftransmission and younger age groups have greater predisposition to HBV andother STIs including HIV/AIDS. This study was designed to determine theprevalence of HBV and assess the knowledge, attitude and sexual behaviour ofstudents of the University of Buea concerning HBV infection. A descriptivecross sectional study was carried out from December 2011 to July 2012 involving320 students of the University of Buea residing in hostels in the mainresidential quarter, Molyko. Structuredquestionnaires were administered to the participants selected using the multistage random sampling technique. Results revealed that 70% of the participantshad already had sexual debut and majority (59.8%) had negative sexual behavior.Among students who had sexual debut, majority (61.6%) did not use a condom atsexual debut, 37.5% had multiple sex partners (≥2) during the preceding twelvemonths, while 15.5% of the males and 6.6% of the females have never used acondom. A reasonable percentage (64.5%)had little or no knowledge on the modes of transmission or prevention of HBV,and 63.7% of the students interviewed did not perceive themselves as being atrisk of HBV, hence was frequently involved in risky sexual practices. Female students had more positive attitudetowards infected persons than males. These findings justify the prevalence rateof HBV of 7.7% found amongst 181 participants who carried out the HBsAg test. Thepoor knowledge on HBV infection and prevention, including high risk sexualpractices express the need for elaborate sensitisation and possible vaccinationprogrammes for university students and Cameroonian youths.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
