A survey questionnaire comprising 20 questions on melatonin was developed and response obtained from 42 students. Demographic data and responses were gathered and evaluated. Descriptive statistics were used to analyze the responses.
Most of the respondents had adequate knowledge about melatonin ranging from 54.8 to 92.6%. There was no statistical difference when responses were analyzed based on the gender of the survey participants. To specific questions whether melatonin is associated with weight gain, can help with signs and symptoms of cancer, recommend sleep hygiene instead of melatonin, and
whether melatonin is addictive, the majority (57.1%, 42.9%, 64.3% and 69.0%, respectively) provided the wrong responses.
