The aim of this study was to examine the association between dietary supplement use and sociodemographic factors in an Australian university population. Additionally, reasons for use of specific dietary supplements were explored.
A cross-sectional online questionnaire was completed by 1633 students and staff members of Griffith University, Queensland, Australia (76% female). The questionnaire collected information on sociodemographic characteristics, use of dietary supplements, and reasons for use of each dietary supplement reported. Multiple regression analyses were used to describe the relationship between demographic factors and dietary supplement use. Pearson χ(2) was used to identify correlations between frequency of dietary supplement use and selected demographic factors. Frequency distributions were used to explore the reasons for use of each dietary supplement reported.
Vitamin or mineral use and use of "other" dietary supplements was reported by 69% and 63% of participants, respectively. Age, sex, ethnicity, and physical activity were independently associated with dietary supplement use. Age, sex, and income were associated with acute use of specific dietary supplements during illness or injury. The reasons for use of specific dietary supplements were closely aligned with marketed claims. Broad reasons of health were commonly reported for use of most dietary supplements.
Use of dietary supplements in this population reflects that of other countries. Individuals were unsure of the benefits and risks associated with dietary supplementation. Health professionals should account for dietary supplements when assessing diet. These results also warrant consideration by regulating bodies and public health officers to ensure safe practices.
本研究旨在调查澳大利亚大学生群体中膳食补充剂的使用情况与社会人口统计学因素之间的关联。此外，还探讨了使用特定膳食补充剂的原因。
澳大利亚昆士兰州格里菲斯大学的1633名学生和教职员工（76%为女性）完成了一项横断面在线问卷。该问卷收集了社会人口统计学特征、膳食补充剂的使用情况以及所报告的每种膳食补充剂的使用原因等信息。采用多元回归分析来描述人口统计学因素与膳食补充剂使用之间的关系。使用Pearson χ(2)检验来确定膳食补充剂使用频率与选定人口统计学因素之间的相关性。使用频率分布来探讨所报告的每种膳食补充剂的使用原因。
分别有69%和63%的参与者报告使用维生素或矿物质以及“其他”膳食补充剂。年龄、性别、种族和身体活动与膳食补充剂的使用独立相关。年龄、性别和收入与疾病或受伤期间特定膳食补充剂的急性使用有关。使用特定膳食补充剂的原因与市场宣传的功效密切相关。大多数膳食补充剂的常见使用原因是出于健康方面的考虑。
该人群中膳食补充剂的使用情况与其他国家相似。个体对膳食补充的益处和风险并不确定。健康专业人员在评估饮食时应考虑膳食补充剂。这些结果也值得监管机构和公共卫生官员考虑，以确保安全使用。
