Consumption of energy drinks has become popular in students but there has been little research regarding energy drink consumption patterns in college students in Pakistan. Aim: To determine energy drink consumption patterns in college students, prevalence and frequency of energy drink use and the perception of students about benefits and hazards of energy drinks consumption. Methods: A cross sectional study was conducted on total of 180 medical students of Nowshera from all years of medical course from Jan 2019 to Dec 2019. 180 medical students were selected through convenient sampling technique.

Background: Hepatitis B (HBV) is a common chronic viral disease that affects liver. About 7% people worldwide are infected with HBV with the majority of the cases seen in developing countries with limited medical facilities. It is a blood-borne disease and contributing factors for risk assessment varies from place to place. Aim: To acquire key factors for risk assessment of hepatitis B patients of the northern area of Pakistan. Methods: A case-control study was done among the patients visiting Ayub Teaching Hospital for a regular checkup. The sample included 80 cases and 80 controls by the non-probability convenient method. Data was collected using a structured questionnaire and analyzed by SPSS 23. Frequencies, mean, standard deviation, p values and odds ratio were calculated. Results: A total of 160 subjects were included in this study(80 controls & 80 cases of HBV. Mean age for cases was 38.74±13.597 years. Odds ratios and p values were calculated for different factors. The odds ratio for a history of blood transfusion, sharing toothbrushes, eliciting injectable drugs, history of recent dental procedure and surgical procedure were 1.581, 1.116, 2.206, 1.581 and 1.165 respectively. Conclusion: Although not significant, yet, low socioeconomic status, family history and piercing ears/nose and tattoos resulted in a higher percentage ascontributing factors of HBV infection. In Northern areas of Pakistan, these factors for risk assessment of hepatitis B should be kept in mind and proper disease awareness and primary prevention program should be observed.
