Abstract
BackgroundHealth supplement (HS) products that are available in the Emirate of Dubai (United Arab Emirates; UAE) contain chemicals that may adversely affect human health. This study aimed to investigate the prevalence of, and factors associated with HS consumption, knowledge, related adverse events, and reporting practices of adverse events amongst the general population in Dubai, UAE.MethodsA cross-sectional household telephone survey using a computer-assisted questionnaire was conducted amongst a random representative sample (n = 1203) of the Dubai population that assessed HS use and knowledge. Dependent variables were supplement use and reports of adverse events while independent variables included socio-demographic factors, knowledge, attitudes, and practice. Logistic regression analysis was performed to identify factors independently associated with HS use.ResultsAmong the 1203 participants in this study, 455 (37.8%) reported ever using HS. Amongst ever-users, reasons for use were to improve health (66.1%), for bodybuilding (9.9%), disease prevention (6.8%), and weight management (5.3%). The majority of users purchased their HS from pharmacies (88.4%) or were prescribed HS (46.6%). Vitamins were the most commonly used HS (87.9%) followed by minerals (10.5%) and sports nutrition products (10.5%). Only 2.9% of users experienced an adverse event associated with HS use which all resolved when the HS was discontinued. Only three of those affected reported the incident. Multivariate logistic regression analysis revealed that HS use was independently associated with female gender (adjusted odds ratio [AOR]; 3.26, 95% confidence interval [CI]: 2.26–4.70), higher income (AOR 2.41, 95% CI: 1.20–4.83), being a past-smoker (AOR 2.39, 95% CI: 1.27–4.48), having an allergy (AOR 1.75, 95% CI: 1.14–2.66), more frequent doctor visits (AOR 1.86, 95% CI: 1.02–3.39), taking prescribed medications (AOR 1.47, 95% CI: 1.04–2.06), and knowledge about HS (AOR 3.91, 95% CI: 2.26–6.76).ConclusionsOur study provides the first population-based estimates of HS use and HS-related adverse events in the Gulf region. Adverse events associated with HS are infrequent and this may be due to the well-developed regulatory framework in Dubai and the high level of knowledge amongst consumers who mainly consume vitamins and minerals on the advice of pharmacists or healthcare professionals.
Highlights
In the Emirate of Dubai (United Arab Emirates; UAE) dietary and herbal supplements are combined under a common definition of “health supplements” (HS) [1]
As Health supplement (HS) products have a wide range of possible actions, their effectiveness and safety for human consumption is of concern since harmful adverse events have been reported following the use of some types of HS products [4]
John’s wort (Hypericum perforatum), a plant derived product that is used to treat mild and moderate depression, can induce liver enzymes and has the potential to interact with many narrow therapeutic range medicines that are metabolized by the liver such as antidepressants [10]
Summary
In the Emirate of Dubai (United Arab Emirates; UAE) dietary and herbal supplements are combined under a common definition of “health supplements” (HS) [1] This definition includes a wide variety of products ingested in many forms (e.g. capsules, tablets, powders, and liquids) containing vitamins, minerals, amino/fatty acids, herbs, and other dietary components to meet or improve essential nutritional requirements [1]. Such supplements may contain one or more different chemical ingredients which can cause adverse events by their chemical reactions within the human body. This study aimed to investigate the prevalence of, and factors associated with HS consumption, knowledge, related adverse events, and reporting practices of adverse events amongst the general population in Dubai, UAE
