The prevalence and risk factors of irritable bowel syndrome (PRIBS study) among adults in low‐ and middle‐income countries: A multicenter cross‐sectional study

Le résumé fourni par la source

Background and Aims: Because of the plenty and abundance of risk factors and the expected increase in the prevalence of irritable bowel syndrome (IBS) in the world in general and in low- and middle-income countries in particular, this international cross-sectional study was conducted in 15 low- and middle-income countries according to our previous protocol, NCT05340400. Methods: Participants were recruited in the period from April 22, 2022 to June 14, 2022. The diagnosis of IBS was according to ROME IV. We determined the physical activity, daily stress, and fatigue of the participants. A large number of collaborators were chosen from different regions and institutions within each country to achieve diversity within the sample and reduce the probability of bias. Results: -value < 0.001). In addition to the previously known risk factors for IBS such as female sex, smoking, psychological stress, and chronic fatigue, other risk factors were discovered such as chronic diseases, including high blood pressure and diabetes, allergies to some substances, previous infection with COVID-19, and the participant having a first-degree relative with a patient. There are also some other modifiable risk factors, such as an abnormal body mass index (whether high or low), smoking, a protein- or fat-rich diet, drinking caffeine-containing beverages, and poor physical activity. Conclusions: Highlighting the prevalence and increasing risk factors of IBS in developing countries should draw the attention of those responsible for health care in these countries and reduce the risk factors.
