Knowledge, Consumption Pattern, and Adverse Effects of Energy Drinks among Asian Population: A Cross-Sectional Analysis from Malaysia

Abstract

Background. The frequent expansion of the energy drinks (EDs) market has caused an extensive increase in the consumption of EDs, especially among younger populations. However, the lack of knowledge on EDs and their perceived beneficial effects could lead to excessive EDs consumption, which is strongly associated with serious side effects. This study aimed to assess the knowledge and perceived beneficial effects of EDs consumers and determine the consumption patterns and side effects experienced by different EDs consumers among the Malaysian population. Methods. A descriptive cross-sectional study was conducted in Malaysia from February to April 2021. A structured and validated questionnaire, consisting of 5 sections with 46 items, was distributed online. Only 515 out of 591 invited participants agreed to participate in the study. Descriptive and inferential analysis were done using SPSS. Results. The median age of participants was 23 ± 7.3 years. The majority of participants (65%) were unaware of the active ingredients of EDs, and approximately 40% of them had no idea that EDs contain caffeine. The main reason for consuming EDs was to stay awake (43%), and Red Bull was the most preferred brand (57%). Lack of rest (57%), headache (53%), and nervousness (49%) were the most experienced side effects. A significant difference was observed between consumption patterns and knowledge and perceived beneficial effects ( $p<0.05$ ). Our data showed a significant association between respondents’ demographic data (e.g., coffee intake, smoking, and alcohol status) and their consumption pattern. Conclusion. ED consumers in Malaysia were found to have limited knowledge on EDs. Therefore, attention should be drawn to the Ministry of Health regarding the significant side effects such as palpitation and nervousness experienced by ED consumers. Hence, awareness ought to be raised by adopting regulations or policies to regulate the sales and warning labels of EDs in Malaysia.
