Journal Title: Roczniki Państwowego Zakładu Higieny - Year 2014, Vol 65, Issue 4
Abstract
Background. There is currently many over the counter products on the market that exert nutritional or physiological effects on the human body. The differences between dietary supplements and non-prescription drugs are however poorly understood by the average consumer and may thus affect their expectations as to the desired effect produced on the body. Objectives. To evaluate patients’ knowledge and attitudes towards dietary supplements as compared to non-prescription drugs. Materials and Methods. Subjects were 335 patients of the Mazowiecki Voivodeship Hospital in Warsaw, Poland. The data were collected from a face-to-face interview using a single and multiple choice questionnaire with 10 questions on dietary supplements. Statistical analysis used the Chi-square (χ2) test. Results. The majority of respondents were found to be familiar with the term ‘dietary supplements’, but had difficulties in classifying these products into appropriate categories. Over 55% do not consider dietary supplements to be foodstuffs and more than 40% considered such products to be drugs. Most respondents thought that the main purpose of taking dietary supplements is to improve nutrition, but over one third expected them to also treat disease. Over 70% declared taking notice to which category the non-prescription products they bought belongs to ie. whether non-prescription drugs (medicinal products) or dietary supplements. Conclusions. Many patients mistakenly believe that dietary supplements are drugs and can be used to treat disease and health disorders.
