Rise in IBDs Likely in Developing Countries, Study Predicts
Researchers have found that the prevalence of inflammatory bowel disease (IBD) in developing countries is likely to rise over the next several years. The study "Worldwide incidence and prevalence of inflammatory bowel disease in the 21st century: a systematic review of population-based studies" was published in The Lancet. One of the study co-authors, Siew Ng, PhD, commented in a press release written by Genevieve Juillet, "As newly industrialized countries become more westernized, we can clearly see that the incidence of IBD is also rapidly rising." Ulcerative colitis was first identified in 1875 and Crohn's disease was identified in 1932. Since then, the incidence of these two diseases have dramatically increased in the western world. The high prevalence of IBD over the past decade indicates that it is an emerging public health challenge. However, little is known about the prevalence of IBD in developing countries. Ng and colleague Gilaad Kaplan, MD, searched the literature for population studies that reported incidence or prevalence of IBDs, including ulceritis colitis and Crohn's disease, between 1990 and 2016. They discovered some interesting trends. In the early to late 20th century, incidence of IBD rose sharply in western countries. However, since 1990, incidence rates have either stabilized or declined in these parts of the world. Despite this plateau in incidence, the prevalence of the disease is still high. Up to 0.3 percent of the population in western countries including North Amer
