Prevalence of irritable bowel syndrome and metabolic syndrome among young adults in an annual health check-up setting.

Background And Aim: Some studies have found a positive association between irritable bowel syndrome (IBS) and metabolic syndrome; however, none are from India.

Methods: We conducted a cross-sectional study of 1040 adults aged between 18 and 50 years. Individuals from the annual health check-up setting were screened using anthropometry and biochemistry. Based on the results, they were identified as with and without metabolic syndrome. We excluded individuals who were already diagnosed with metabolic syndrome or those who were already on medication for diabetes mellitus or hypertension or dyslipidemia. All the participants were administered the Rome III questionnaire for the diagnosis of IBS.

Results: Metabolic syndrome was found in 307 of 1040 (29.5%) while 33 of 1040 (3.2%) had IBS. The proportion of IBS was not significantly different between participants with and without metabolic syndrome (1.6% 3.8% respectively;  = 0.06). Those with IBS had significantly greater mean weight (72.4 67.2 kg;  = 0.009), mean waist circumference (88.8 85.2 cm;  = 0.011), mean body mass index (BMI) (26.2 24.2 kg/m;  = 0.002), and higher mean fasting glucose (96 89 mg/dL;  < 0.000) respectively.

Conclusion: The prevalence of metabolic syndrome and IBS are comparable to previous literature from India. There was no association between metabolic syndrome and IBS.
