Title: Reproductive Issues in Rheumatic Disorders Poster

Session Type: Poster Session A

Session Time: 10:30AM-12:30PM

Background/Purpose: Although guidelines support acceptability of breastfeeding (BF)/pumping in women with systemic rheumatic diseases (SRDs) when taking BF-compatible medications, little is known about factors influencing infant feeding practices. We describe infant feeding practices (BF/pumping versus exclusive formula feeding [FF]) and factors influencing infant feeding among women with SRDs at first delivery.

Methods: Women aged 18-65 years evaluated by a Hospital for Special Surgery rheumatologist ≥2 times from 2020-2022 were enrolled in the Rheumatology Women’s Reproductive Health and Wellness Cohort. Characteristics of women with SRDs (identified by ICD-10 code-based algorithm) and non-SRD musculoskeletal conditions who self-reported delivering ≥1 child and answered questions on maternal and fetal characteristics, postpartum medication use, infant feeding practices, factors influencing infant feeding practices (each domain rated 0: “not at all influenced” to 5: “strongly influenced”), and satisfaction level for their first delivery were tabulated. We used descriptive analyses to compare maternal and fetal characteristics and factors influencing infant feeding practices in women who BF/pumped versus those who FF exclusively. We also stratified by satisfaction level (very/somewhat satisfied versus neither satisfied nor dissatisfied/very/somewhat dissatisfied) with infant feeding practices.

Results: Of 158 respondents, 56% with SRD and 44% with non-SRD musculoskeletal conditions, 113 (72%) BF and 45 (40%) exclusively FF; among those with SRD, 56 (66%) BF and 29 (34%) exclusively FF. No significant differences in maternal disease characteristics were noted between those who BF versus FF (Table 1). While a higher proportion of those who BF used no medications postpartum (p< 0.01), use of BF-compatible disease modifying and biologic medications postpartum was more common among those who FF exclusively (p< 0.01). Among those with SRD, factors associated with infant feeding practices included rheumatology/musculoskeletal medication use, experience or expectations of loved ones, social media, and workplace policies or expectations (p < 0.03) (Table 2). Respondent characteristics did not differ by satisfaction level with infant feeding experience, and among those with SRD, only breast discomfort and/or lack of milk production was significantly associated with satisfaction with infant feeding practices (p< 0.01) (Table 3).

Conclusion: Infant feeding practices vary among those with SRD. Multiple factors, some related to SRD and others unrelated to SRD, are associated with infant feeding practices. Awareness of infant feeding practices is needed for rheumatologists to develop patient-centered strategies related to infant feeding that will ensure feeding strategies align with patient preferences and best practices.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
