Biopsychosocial factors are associated with impaired sexual function in Mexican patients with rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic disease with worldwide representation that impacts every domain of a patient´s life, extending to sexual and reproductive domains. The study characterized sexual health (SH) and reproductive health (RH) in Mexican RA outpatients and identified factors associated with impaired sexual function (ISF).

From September 1, 2020-January 31, 2022, consecutive RA participants had semi-structured interviews focusing on their SH and RH biographies, and self-administered questionnaires were applied to assess patient-reported outcomes, including fatigue with the Functional Assessment of Chronic Illness Therapy-Fatigue scale (FACIT-F). ISF was defined based on published cut-offs of the International Index of Erectile Function (IIEF) in males and the Female Sexual Function Index (FSFI) in females (≥1 sexual intercourse in the last four weeks was required for index scoring). Multivariable logistic regression analysis was used to identify the factors associated with ISF.

There were 268 participants, and 246 (91.8%) were females. Participants had 13 years of disease duration. Among females, 151 (61.4%) had FSFI applied, and the satisfaction domain was impaired in 111 (73.5%). Among males (N = 22), 17 (77.3%) had IIEF applied, and erectile dysfunction was present in 5 (29.4%). Almost half of the participants denied using a family planning method, were in their 50s, and receiving teratogenic drugs; 89.7% of the participants had children. ISF was detected in 94 (62.3%) females and 3 (17.6%) males. Male sex (aOR: 0.07, 95%CI: 0.01-0.36, p = 0.001), FACIT-F score (aOR: 0.96, 95%CI: 0.92-1.00, p = 0.03), and cohabitation with the couple (aOR: 0.32, 95%CI: 0.11-0.96, p = 0.04) were associated with ISF.

We observed a disproportionate burden of ISF among women with RA compared to male participants. Male sex, lesser fatigue, and cohabitation with the couple were protective against ISF. Regardless of the prevalent use of teratogenic medications, contraceptive use was suboptimal among the participants.
