In the light of the changing pattern of the consumption of dietary supplements among adults in other countries during the COVID-19 pandemic, we aim to assess the prevalence of the consumption of dietary supplements with respect to the purpose of consumption and sociodemographic factors among adults in Lithuania. This study included two samples of adults from Lithuania: 870 in 2019 and 1600 in 2021. Anonymous original questionnaires were used to collect the data about the consumption of dietary supplements before and during the pandemic. The consumption of dietary supplements was prevalent among 67.2% and 78.1% of the samples, respectively. Although the majority (73.7%) of the respondents indicated that the pandemic had no effect on their use of dietary supplements, every fourth respondent’s (24.6%) consumption increased. In 2021, the consumption was more prevalent among females, respondents with university education, urban citizens, employed respondents, respondents without children, with higher income, and those who knew a person with COVID-19 (p < 0.05). During the pandemic, the strengthening of the immune system and the body were the leading reasons for consumption (49.0% and 43.5%, respectively). The consumption of dietary supplements appropriate for these purposes increased among 63.3% and 66.9% of respondents, respectively. To conclude, the consumption of dietary supplements among adults in Lithuania increased during the COVID-19 pandemic.
鉴于 COVID-19 大流行期间其他国家成年人膳食补充剂消费模式的变化，我们旨在评估立陶宛成年人消费膳食补充剂的流行情况，包括消费目的和社会人口因素。本研究包括立陶宛的两个成年人样本：2019 年 870 人和 2021 年 1600 人。匿名原始问卷用于收集大流行前后关于膳食补充剂消费的数据。膳食补充剂的消费在 2019 年和 2021 年的样本中分别分别为 67.2%和 78.1%。尽管大多数（73.7%）受访者表示，大流行对他们使用膳食补充剂没有影响，但每四个受访者（24.6%）的消费增加。2021 年，女性、受过大学教育、城市居民、就业受访者、没有孩子的受访者、收入较高以及认识 COVID-19 患者的受访者（p<0.05）的消费更为普遍。在大流行期间，增强免疫系统和身体是消费的主要原因（分别为 49.0%和 43.5%）。分别有 63.3%和 66.9%的受访者增加了消费这些目的的适当膳食补充剂。总之，立陶宛成年人在 COVID-19 大流行期间增加了膳食补充剂的消费。
