To evaluate the impact of educational text messages (TMs) on folate/folic acid knowledge and consumption among college-aged women, and to evaluate the impact of providing folic acid supplements on folate/folic acid intake among college-aged women.
A total of 162 women (18-24 years) recruited from a university.
The protocol included 3 study visits and a 6-week intervention for 4 groups: control; TM only; supplement only; and TM+supplement. Supplement groups received folic acid-containing supplements. TM groups received 18 folate-related TMs. Participants completed knowledge quizzes, supplement intake questions, a self-efficacy scale, and dietary recalls.
Despite receiving the same folic acid education, intake of folic acid and total folate was greater in the supplement groups compared with the non-supplement groups at mid- and post-study. TMs had no impact on any study measure.
Provision of a folic acid-containing supplement enhanced short-term folic acid intake, supporting the provision of supplements to this population group.
评估教育短信对大学适龄女性叶酸/叶酸知识及摄入量的影响，并评估提供叶酸补充剂对大学适龄女性叶酸/叶酸摄入量的影响。
从一所大学招募了共162名年龄在18至24岁之间的女性。
该方案包括3次研究访视以及针对4组人群的为期6周的干预措施：对照组；仅接收短信组；仅接受补充剂组；以及短信+补充剂组。补充剂组接受含叶酸的补充剂。短信组接收18条与叶酸相关的短信。参与者完成了知识测验、补充剂摄入问题、自我效能量表以及饮食回忆。
尽管接受了相同的叶酸教育，但在研究中期和后期，补充剂组的叶酸和总叶酸摄入量高于非补充剂组。短信对任何研究指标均无影响。
提供含叶酸的补充剂可提高短期叶酸摄入量，支持向该人群提供补充剂。
