Prevalence of Self-reported Gluten Sensitivity in a Population of High-school Students

Detailed Summary

It has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'Non-Celiac Wheat Sensitivity' (NCWS), since it is not known what component of wheat causes the symptoms in NCGS patients, and the investigators also showed that these patients had a high frequency of coexistent multiple food hypersensitivity. To our knowledge, there are very few studies which assessed the prevalence of self-reported gluten-related symptoms in the community and analyze diagnostic outcomes in those referred to secondary gastrointestinal care. In one of these, performed in UK, the authors showed that gluten-related symptoms are self-reported by 13% of the population, with 3.7% consuming a gluten-free diet, despite only 0.8% being aware that they have a formal diagnosis of celiac disease. Of those patients presenting to the gastroenterology department, the majority do not have CD but NCWS. No data are available for boys and girls. Therefore, the aims of this study were 1) to determine the prevalence of self-perceived gluten-sensitivity in a population of high-school students, and 2) to evaluate the demographic and clinical differences between students self-reporting gluten sensitivity and students not reporting food hypersensitivity.
