There are a multitude of cross-sectional surveys that examined the prevalence of irritable bowel syndrome (IBS) in the community.
However, data regarding the influence of socioeconomic status on prevalence of IBS are sparse.
Dr You-Ming Li and colleagues from China investigated the possible relation between human development and prevalence of IBS, at national level.
EMBASE Classic, EMBASE, and MEDLINE were searched to identify population-based studies that reported prevalence of IBS.
|The ratio of female/male prevalence was correlated with national HDI|
|Journal of Gastroenterology & Hepatology|
The team chose the Human Development Index (HDI) to assess socioeconomic status at national level.
The researchers observed no correlation between prevalence of IBS and national HDI.
The team found no statistically significant difference in the prevalence between developing and developed countries.
The ratio of female/male prevalence was correlated with national HDI, and the ratio in the developing was significantly lower than that in the developed countries.
Dr Li's team comments, "This study is the first to investigate the relation between IBS prevalence and national socioeconomic status, with consideration of years, gender, and other factors."
"We demonstrate that national development is not a direct indicator for prevalence of IBS."
