A total of 1983 responses were analyzed, 1614 (81.4%) by CD adults and 369 (18.6%) by parents\/caregivers of CD children\/adolescents. The compliance with the GFD was unchanged for 69% of the adults and 70% of the children, and improved for 29% of both. The factors increasing the probability to report stricter compliance were the presence of CD symptoms in the last year before the lockdown (odds ratio (OR) 1.98, 95% confidence interval (CI) 1.46\u20132.26), a partial usual adherence to gluten-free diet (GFD) (OR 1.91, 95% CI 1.2\u20133.06), and having tried recipes with naturally gluten-free ingredients more than usual (OR 1.58, 95% CI 1.28\u20131.96) for adults; the presence of CD symptoms in the last year (OR 2.05, 95% CI 1.21\u20133.47), still positive CD antibodies (OR 1.89, 95% CI 1.14\u20133.13), and other family members with CD (OR 2.24, 95% CI 1.3\u20133.85) for children\/adolescents. Therefore, the lockdown led to a reported improved adherence to the GFD in one-third of the respondents, in particular in those with previous worse disease control, offering the opportunity to avoid sources of contamination\/transgression and increase the use of naturally gluten-free products.<\/jats:p>","DOI":"10.3390\/nu12113467","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T10:00:32Z","timestamp":1605175232000},"page":"3467","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Adherence to the Gluten-Free Diet during the Lockdown for COVID-19 Pandemic: A Web-Based Survey of Italian Subjects with Celiac Disease"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6676-5773","authenticated-orcid":false,"given":"Alice","family":"Monzani","sequence":"first","affiliation":[{"name":"Division of Pediatrics, Department of Health Sciences, Universit\u00e0 del Piemonte Orientale, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Lionetti","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Marche Polytechnic University, 60020 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico","family":"Felici","sequence":"additional","affiliation":[{"name":"Pediatric and Pediatric Emergency Unit, Children Hospital, 15121 Alessandria, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucia","family":"Fransos","sequence":"additional","affiliation":[{"name":"Piedmont Section, Italian Celiac Association, 10136 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8185-5742","authenticated-orcid":false,"given":"Danila","family":"Azzolina","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine, Unit of Medical Statistics and Cancer Epidemiology, Universit\u00e0 del Piemonte Orientale, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4173-146X","authenticated-orcid":false,"given":"Ivana","family":"Rabbone","sequence":"additional","affiliation":[{"name":"Division of Pediatrics, Department of Health Sciences, Universit\u00e0 del Piemonte Orientale, 28100 Novara, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Catassi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Marche Polytechnic University, 60020 Ancona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2020, June 18).
