Self-medication among secondary school pupils in Hong Kong: a descriptive study.

A self-completion questionnaire was used to survey self-medication among secondary school pupils in Hong Kong. Data were collected from 4793 pupils aged 10 to 23 years (55.9% female and 44.1% male). Nearly three quarters (72.1%) had taken self-medication without consulting a medical practitioner and 51.8% of the sample had done so without the knowledge of older family members. The prevalence of self-medication increased with age. More than half the pupils (50.4%) indicated that trivial illness did not warrant a consultation with a doctor. Information relating to the sources of self-administered drugs, types of drugs used and sources of information about these drugs was collected. Medicine cabinets at home and pharmacy shops were the two most common places from which the pupils obtained their drugs. Though the prevalence of taking tranquillizers and sleeping tablets was found to be low, the probability of young people, especially boys, obtaining dangerous drugs from these places should not be overlooked. The medical, nursing and teaching professions should take a more active role in health education, as the sources from which the pupils obtained their drug knowledge, in descending order of frequency, were: family members, previous illness experience, pharmacy shops, doctor or nurse, television or radio, newspapers or magazines, friends and teachers.
