Multiple sclerosis and pregnancy: a comparison study

To determine whether different health care systems may affect reproductive decision-making among patients with Multiple Sclerosis (MS), we describe the reproductive practices and attitudes of Canadian MS patients ascertained from the multidisciplinary MS Clinic at Hôpital Notre-Dame in Montreal, Quebec (NDMSC), in comparison to those of matched American self-registrants from the database of the North American Research Committee on Multiple Sclerosis (NARCOMS).

A total of 665 self-administered questionnaires on reproductive practices were sent out to eligible attendees attending the NDMSC. The short questionnaires were completed and returned to the authors in an anonymous format for analysis.

A total of 459 completed questionnaires were returned. The majority of NDMSC respondents (72.5%) and NARCOMS subset (75.2% females), did not encounter a pregnancy following diagnosis of MS. The most common MS-related reason for this decision was "symptoms interfering with parenting" (75.0% for the NDMSC, 72.6% for the NARCOMS). The most commonly reported non-MS-related reason was "a completed family" by the time of diagnosis in both the NDMSC and NARCOMS subset (58.0%, 40.4%, respectively). Concerns about financial issues both related and unrelated to MS were also commonly reported by males and females in both cohorts but significantly more so among the NARCOMS participants.

These results indicate that reproductive decisions of MS patients are highly affected by their illness and its associated disability, regardless of the available health care program. Health care providers should discuss their patients' reproductive needs and perceptions to help them make more informed decisions.
