Objective: To determine the prevalence of Intestinal bowel Syndrome (IBS) on Chiclayo - Peru during 2011. Material and methods: target population: people aged 18 to 60 years. Study Design: Cross-sectional. Sample size: 195 persons, multistage stratified random sampling. House to house were interviewed using a data collection sheet based on Rome III criteria. Descriptive statistics were used and then exploratory bivariate analysis to measure association between IBS and epidemiological variables. Results: 200 people were interviewed, mean age was 12.7 ± 38.8 years. There were 76 males (38%) and 124 women (62%), the prevalence of IBS was 15% (9 men and 21 women); the most painful abdominal area was: mesogastrium (26.7%), predominatin "pasty" stools (30%) and "diarrhea" (36.7%), 20 people with IBS (66.7%) worked and/or studied. There was neither association between IBS and sex nor the "occupation" (prevalence odds: 1.51 95% CI: 0.31 - 3.99 and 1.23, 95 %: CI: 0.51 to 3.15, respectively).
