Socio-demographic factors, beliefs and health perceptions associated with use of a commercially available Ω-3 fatty acid supplement: A cross-sectional study in Asian countriesParmenter, Benjamin HaddonBumrungpert, AkkarachThouas, George AnthonyPharmaNutrition 2021 v.15cognitioncross-sectional studiesfatty acidsfemalesincomemusculoskeletal systemquality of lifeChinaThailandVietnam7171382Limited studies have reported on socio-demographic factors, beliefs and health perceptions related to ω-3 supplement use in Asia. We aimed to examine characteristics associated with use of an ω-3 supplement in Asia.Adults residing in Thailand, China and Vietnam (n = 904; mean ± SD age, 31.3 ± 9.1 years; sex, 70.4 % female; education, 65.3 % to tertiary level) completed a cross-sectional survey, with 214 reporting use of the ω-3 product (Dasbrain®).Use of the ω-3 product was significantly higher among those reporting higher education, income or quality of life, as well as musculoskeletal or cognitive conditions. Participants who perceived the ω-3 product as proven by research, safe, and natural were significantly more likely to use the product, as were those with higher self-perceived knowledge of ω-3. The most common perceived benefits of the ω-3 product included “support of overall health/wellbeing” (63.5 %) and “cognitive performance” (49.3 %), however, these were not associated with higher likelihood of use.Use of the ω-3 product is associated with higher socio-demographic status and belief in its safety and efficacy among adults residing in Asia. Users and non-users alike show similar beliefs about the potential health benefits of the ω-3 product.2021-03article
