Abstract: | HLA molecular typing for celiac disease (CD) is a genetic test with a high negative predictive value. The aim of this study is to explore knowledge of and attitudes towards genetic testing (GT). A 25-item questionnaire was developed by a multidisciplinary team and distributed to members of CD support groups across the United States. Respondents (n?=?1835) were mainly female (88 %), married (76 %), and college-educated (55 %), with a median age range of 31–50 years. Those who were married (82 vs 75 %, p?=?0.002), had children (82 vs 74 %, p?0.001), and had pursued education beyond high school (81 vs 68 %, p?=?0.004) were more likely to be aware of the availability of GT. On multivariable analysis, adjusting for age, sex, education, marital status, region of residence, and having children, college-education (OR 2.05, 95 % CI: 1.33–3.16) and having children (OR 1.56, 95 % CI: 1.15–2.11) remained significant predictors of GT awareness. A majority of patients with a personal or family history of CD planned GT for their children, and the most common concerns regarding GT were cost and impact on health care and/or insurance. In conclusion, awareness of GT is high among CD support group members. Efforts should be made to increase knowledge of GT in those with a lower educational level, and healthcare professionals should attempt to address concerns regarding GT cost and the impact of results on health care and insurance status. |
