419 A CTS team approach to identifying thematic constructs related to kratom use during pregnancy and breastfeeding: A qualitative analysis of social media posts

OBJECTIVES/GOALS: Research on the safety of perinatal kratom use - an herb that acts on opioid receptors - is scarce. Our transdisciplinary clinical and translational science (CTS) team is conducting parallel qualitative analyses of subreddit posts related to kratom use during (1) pregnancy and (2) breastfeeding. METHODS/STUDY POPULATION: Pregnancy- and breastfeeding-related keywords are being used to extract posts and selected metadata from the following subreddit communities: r/kratom, r/quittingkratom, r/pregnant, and/or r/breastfeeding. After the removal of duplicate posts, posts written in a non-English language and those that state in the post text and/or title that they were published by minors ( RESULTS/ANTICIPATED RESULTS: Among the eligible posts, the number of unique usernames of the sources publishing the posts; the range of publication dates; and the mean, median, & range of the number of comments per post will be presented. Inter-rater concordance in thematic coding will be computed. A word cloud will be created with the most used nouns from the eligible posts. Verbatim quotes will be shown to illustrate themes depicted in the sample. The quantitative and qualitative analyses will be conducted separately for the posts related to kratom use during pregnancy and breastfeeding. DISCUSSION/SIGNIFICANCE: These findings could assist clinicians in identifying questions that obstetric patients may have regarding the perinatal use of this emerging substance of concern. Further research is needed to validate these findings using other social media data, such as Twitter.
