| Summary: | Hepatitis C virus infection has increasingly become a public health concern in both
developed and developing countries. The World Health Organization reported that 71
million persons were living with this chronic hepatitis C virus infection worldwide with
global incidence rate accounted for 23.7 per 100,000 population. Malaysia is also
reported to have nearly 330 000 adults being infected with this virus. In addition to
providing treatment, identifying the potential risk factors to prevent the transmission of
HCV are essential to control the hepatitis C infection. However, many known risk factors
have not been widely explored in Malaysia. Hence, the aim of the study was to identify
the risk factors associated with hepatitis C among adult patients in Kedah state, Malaysia.
The conduct of this study has been approved by the Medical Research and Ethics
Committee of the Ministry of Health of Malaysia. This matched, hospital-based, casecontrol
study was conducted at Hospital Sultanah Bahiyah, Alor Setar, in Kedah state.
Cases were adults (aged ≥18 years) diagnosed with hepatitis C from January 2015 until
December 2018, while controls were age-, gender-, and ethnic-matched and tested
negative for hepatitis C virus. The purpose and method of the study were explained to
all participants before obtaining their informed consent. A questionnaire on demographic
characteristics and previous exposure to listed risk factors were filled up by all study
participants. Association of hepatitis C infection with demographic characteristics,
occupational profile, medical history, high-risk activities, and traditional practices were
assessed using univariable and multiple logistic regression analysis. All data analyses
were performed using R statistical software, Version 3.5.2
A total of 255 case-control patient pairs were enrolled in this study. In both groups,
majority of the patients were male, aged 50-59 years, and of Malay/Bumiputra ethnicity.
Multiple logistic regression analysis indicate that having a history of blood or blood
product transfusion before 1992 (adjusted odds ratio [AOR] 6.99, 95% confidence
interval [CI]: 3.73, 13.81), injection drug use (AOR 6.60, 95% CI 3.66, 12.43), imprisonment (AOR 4.58, 95% CI 1.62, 16.40), tattooing (AOR 3.73, 95% CI 1.37,
12.00), having more than one sexual partner (AOR 2.06, 95% CI 1.16-3.69), body
piercing (AOR 1.71, 95% CI 1.04, 2.80), and having only secondary education (AOR
1.92, 95% CI 1.06, 3.57) were independently associated with hepatitis C.
In conclusion, these findings demonstrate that the risk factor for hepatitis C is
multifactorial. Screening activities should give greater attention to these high-risk groups
to identify undiagnosed HCV-infected individuals. Better access to HCV screening and
treatment at prison and drug rehabilitation facilities, improved public awareness on
unsafe use of illicit drugs and formulating safety guidelines for tattooing and piercing,
were among recommended strategies to control this chronic viral infection in Malaysia. |
