RESUMO
Purpose: Gluten-free diets have gained popularity worldwide. However, little information is available regarding the knowledge of, and behaviors toward, this diet among adults in KSA. This study was aimed at addressing this knowledge gap. Methods: A cross-sectional survey was conducted in 352 women at a health sciences university in KSA. Results: Eleven percent of participants had followed a gluten-free diet at least once, 70% of whom had voluntarily tried this diet without a confirmed medical diagnosis. The main source of information regarding this diet was the internet and social media. Additionally, followers of this diet had moderate knowledge of gluten and its products yet higher knowledge than that of non-followers (65% vs 56%, P = .0055). Following a GFD was associated with an age of 25 years or older, higher education, and being employed. Although 56% of participants reported following this diet 75% or more of the time, the average calculated adherence score was low. Although 95% of the followers indicated changes in their lifestyle and social life, 71% felt better after following this diet, and only 2.6% felt worse. This self-reported results were confirmed by a calculated average quality of life score of 1.3, indicating a good quality of life after following this diet. Conclusion: This study indicated moderate knowledge and low adherence to a gluten-free diet among followers. This finding may be attributable to the high percentage of followers without a confirmed medical condition, or to the social and lifestyle changes faced by followers of GFDs. Educational programs should be introduced to the public to increase awareness of gluten-free foods and diets.
