Health knowledge of women with a fragile X premutation: Improving understanding with targeted educational material.

Abstract

Women who carry a fragile X premutation are at risk for at least two major health conditions and for transmitting fragile X syndrome (FXS) to their children. The two health concerns include fragile X-associated primary ovarian insufficiency (FXPOI) and fragile X-associated tremor/ataxia syndrome (FXTAS). The aim of this study was to evaluate whether written educational information about these conditions would increase knowledge and facilitate communication. Women with a premutation (N=142) completed an online pre-test to assess their knowledge of premutation-associated conditions, and 135 women who provided an address received a booklet titled Women's Health and the Fragile X Premutation. After 3months, 51.1% completed the post-test. Major gaps in knowledge were related to FXPOI and factors associated with repeat expansion. To determine whether the booklet helped to fill gaps in knowledge, we compared pre- and post-test scores. Scores were significantly increased after receipt of the booklet (p<.05, Wilcoxon signed rank test). Participants answered that the booklet was 'very helpful' (44.6%) or 'somewhat helpful' (38.5%). Twenty-four participants (34.8%) reported using the booklet to explain concepts to family members. Although we found that the booklet provided women with needed information, we found that gaps in knowledge still exist.
