To evaluate Lebanese licensed dietitians' knowledge, prevalence of use and recommendation of dietary supplements (DS), and their associated factors.
Cross-sectional survey.
Dietitians across Lebanon were contacted through the telephone and were asked to participate in the study. An online self-administered questionnaire was designed and sent to dietitians either by email or by WhatsApp, between 4 March and 4 May 2020.
This study included 319 dietitians randomly selected from the dietitians' list that was provided by the Lebanese Ministry of Public Health.
Around 75 % of dietitians had a knowledge score above 50 %. Overall, 73·7 % of them have used DS and 46·1 % have recommended them. Higher knowledge score was associated with less years of experience, using scientific articles as source of information on DS, and participating in research. Resorting to pharmacists was significantly associated with both nutrient supplements (NS) and herbal supplements (HS) use, whereas referring to health food stores was associated with HS use only. NS recommendation to patients was associated with personal NS use (OR = 3·38, < 0·001), considering pharmacists as a source of information on DS (OR = 2·29, = 0·01) and discussing DS with patients (OR = 3·82, = 0·01). Having personally used HS (OR = 12·23, < 0·001) and having discussed DS with patients (OR = 8·51, = 0·01) increased the likelihood of recommending HS.
A proper DS education, the elaboration of national scientific guidelines and the implementation of concise laws regarding the regulations of DS would play a crucial role in supporting dietitians' practices and improving the quality of patient care with respect to DS.
评估黎巴嫩有执照的营养师对膳食补充剂（DS）的知识、使用 prevalence 和推荐情况及其相关因素。
横断面调查。
通过电话联系黎巴嫩各地的营养师，邀请他们参与研究。2020年3月4日至5月4日期间，设计了一份在线自填问卷，并通过电子邮件或WhatsApp发送给营养师。
本研究包括从黎巴嫩公共卫生部提供的营养师名单中随机选取的319名营养师。
约75%的营养师知识得分高于50%。总体而言，73.7%的人使用过DS，46.1%的人推荐过DS。较高的知识得分与经验年限较少、将科学文章作为DS信息来源以及参与研究有关。向药剂师咨询与营养补充剂（NS）和草药补充剂（HS）的使用均显著相关，而参考健康食品店仅与HS的使用相关。向患者推荐NS与个人使用NS（OR = 3.38，<0.001）、将药剂师视为DS信息来源（OR = 2.29，= 0.01）以及与患者讨论DS（OR = 3.82，= 0.01）有关。个人使用过HS（OR = 12.23，<0.001）以及与患者讨论过DS（OR = 8.51，= 0.01）增加了推荐HS的可能性。
适当的DS教育、制定国家科学指南以及实施关于DS监管的简明法律，将在支持营养师的实践以及提高DS患者护理质量方面发挥关键作用。
