OBJECTIVE
There has been a dramatic increase in the use of dietary supplements in Western societies over the past decades. Our understanding of the prevalence of Ω-3 fatty acid supplement consumption is of significance for future nutrition planning, health promotion and care delivery. However, we know little about Ω-3 fatty acid supplement consumption or users. This paper, drawing upon the largest dataset with regard to Ω-3 fatty acid supplement use (n=266 848), examines the use and users of this supplement among a large sample of older Australians living in New South Wales.
DESIGN
A cross-sectional study. Data were analysed from the 45 and Up Study, the largest study of healthy ageing ever undertaken in the Southern Hemisphere.
SETTING
New South Wales, Australia.
PARTICIPANTS
266 848 participants of the 45 and Up Study.
PRIMARY AND SECONDARY OUTCOME MEASURES
Participants' use of Ω-3, demographics (geographical location, marital status, education level, income and level of healthcare insurance) and health status (quality of life, history of smoking and alcohol consumption, health conditions) were measured.
RESULTS
Of the 266 848 participants, 32.6% reported having taken Ω-3 in the 4 weeks prior to the survey. Use of Ω-3 fatty acid supplements was higher among men, non-smokers, non-to-mild (alcoholic) drinkers, residing in a major city, having higher income and private health insurance. Osteoarthritis, osteoporosis, high cholesterol and anxiety and/or depression were positively associated with Ω-3 fatty acid supplement use, while cancer and high blood pressure were negatively associated with use of Ω-3 fatty acid supplements.
CONCLUSIONS
This study, analysing data from the 45 and Up Study cohort, suggests that a considerable proportion of older Australians consume Ω-3 fatty acid supplements. There is a need for primary healthcare practitioners to enquire with patients about this supplement use and for work to ensure provision of good-quality information for patients and providers with regard to Ω-3 fatty acid products.
目的
在过去几十年中，西方社会中膳食补充剂的使用急剧增加。了解ω-3 脂肪酸补充剂的消费情况对于未来的营养规划、健康促进和医疗保健提供具有重要意义。然而，我们对 ω-3 脂肪酸补充剂的消费或使用者知之甚少。本文利用最大的 ω-3 脂肪酸补充剂使用数据集（n=266848），在新南威尔士州的一大群老年澳大利亚人中研究了这种补充剂的使用情况和使用者。
设计
横断面研究。数据来自 45 岁及以上研究，这是南半球有史以来规模最大的健康老龄化研究。
地点
澳大利亚新南威尔士州。
参与者
45 岁及以上研究的 266848 名参与者。
主要和次要结果
测量了参与者对 ω-3 的使用情况、人口统计学（地理位置、婚姻状况、教育程度、收入和医疗保健保险水平）和健康状况（生活质量、吸烟和饮酒史、健康状况）。
结果
在 266848 名参与者中，32.6%的人报告在调查前的 4 周内服用过 ω-3。男性、不吸烟者、非重度（酗酒）饮酒者、居住在主要城市、收入较高且拥有私人医疗保险的人群更有可能使用 ω-3 脂肪酸补充剂。骨关节炎、骨质疏松症、高胆固醇和焦虑/抑郁与 ω-3 脂肪酸补充剂的使用呈正相关，而癌症和高血压与 ω-3 脂肪酸补充剂的使用呈负相关。
结论
本研究分析了 45 岁及以上研究队列的数据，表明相当一部分澳大利亚老年人服用 ω-3 脂肪酸补充剂。初级保健医生需要向患者询问这种补充剂的使用情况，并努力确保为患者和提供者提供有关 ω-3 脂肪酸产品的高质量信息。
