BACKGROUND Irritable bowel syndrome(IBS)is a highly prevalent gastrointestinal disorder in children and adults,which increased over the past twenty years.The Mediterranean diet is a well-known diet full of antioxidants and anti-inflammatory ingredients.AIM To evaluate the safety,tolerability,and effects of adherence to the Mediterranean diet on disease patterns in children and adolescents with IBS.METHODS This prospective,cross-sectional case-controlled study included 100 consecutive IBS patients diagnosed according to Rome IV criteria,aged 12-18 years.Patients Group II on their regular diet for six months.Besides IBS scores(IBS-SSS,IBS-QoL,and total score),different clinical and laboratory parameters were evaluated at the start and end of the study.RESULTS The Mediterranean diet was safe and well-tolerated in IBS patients.IBS children and adolescents with good adherence to the Mediterranean diet(KIDMED Score≥8 points);group I showed significant improvement in IBS scores.IBS-SSS in the Mediterranean diet group was 237.2±65 at the beginning of the study and decreased to 163.2±33.8 at the end of the study(P<0.001).It did not show a significant improvement in the group with a regular diet(248.3±71.1 at the beginning of the study compared to 228.5±54.3 at the study end with P<0.05).The mean IBS-SSS in the Mediterranean diet group significantly improved compared with the group with a regular diet.Mean IBS-QoL in group I improved from 57.3±12.9 at the start of the study to 72.4±11.2 at the study end(P<0.001)and significantly improved when compared to its level in group II at the study end(59.2±12.7 with P<0.001),while group II showed no significant improvement in IBSQoL at the study end when compared to the beginning of the study(59.2±11.7 with P>0.05).The mean total IBS score in group I became 28.8±11.2 at the end of our study compared to 24.1±10.4 at the start(P<0.05)and significantly improved when compared to its level in group II at the end of the study(22.1±12.5 with P<0.05),while in group II,non-significant improvement in the total score at the end of our study compared to its mean level at the start of the study(22.8±13.5 with P>0.05).CONCLUSION The Mediterranean diet was safe and associated with significant improvement in IBS scores in children and adolescent patients with IBS.
