ABSTRACT
Objective. To acquire more data about the epidemiologic characteristics of constipation in different kinds of populations in China. Methods. Using "constipation" and "China" as search terms; relevant papers were searched from January 1995 to April 2014. Data on prevalence, gender, diagnostic criteria, geographical area, educational class, age, race, and physician visit results were extracted and analyzed. Results. 36 trials were included. Prevalence rates of constipation in elderly population (18.1%) and pediatric population (18.8%) were significantly higher than that in general population (8.2%). Prevalence of constipation defined by non-Rome criteria was higher than that by Rome criteria in general population. Prevalence rates of constipation were different for different geographical area. People with less education were predisposed to constipation. In pediatric population, prevalence of constipation was the lowest in children aged 2-6 years. Prevalence of constipation in ethnic minorities was higher than that in Han people. People with constipation were predisposed to FD, haemorrhoid, and GERD. Only 22.2% patients seek medical advice in general population. Conclusions. In China, prevalence of constipation was lower compared with most of other countries. The factors including female gender, diagnostic criteria, geographical area, age, educational class, and race seemed to have major effects on prevalence of constipation.

Regional difference in the prevalence of constipation. (a) In general population, the prevalence rate of constipation in Hong Kong was higher than that in Chinese Mainland. (b) In pediatric population, the prevalence rate of constipation in Hong Kong was higher than that in Chinese Mainland. (c) Prevalence rate of constipation in Northern area was significantly higher than that in Southern area in general population and elderly population, while there was no significant difference between Northern area and Southern area in pediatric population. (d) Prevalence rate of constipation in Eastern area was significantly lower than that in Midwestern area in general population, while prevalence rate in Eastern area was significantly higher than that in Midwestern area in elderly population, and there was no significant difference between Eastern area and Midwestern area in pediatric population.

Mentions: In general population, we just compared the cases diagnosed by Rome II criteria considering the diagnostic criteria differences in the prevalence of constipation. The prevalence rate of constipation in Hong Kong was significantly higher than that in Chinese Mainland (14.0% versus 6.4%; χ2 = 43277.5, P < 0.001). Prevalence rate was 15.5% in Northern area and 3.3% in Southern area and there were significant differences between them (χ2 = 7403.5, P < 0.001). Prevalence rate in Eastern area was 4.0% and that in Midwestern area was 11.0%. There was significant difference between them (χ2 = 872.7, P < 0.001). In elderly population, as there were limited studies that reported the epidemiology of Hong Kong, we only analyzed the differences between Northern and Southern area and between Eastern and Midwestern area. Prevalence rates were 25.4% in Northern area, 16.7% in Southern area, 21.8% in Eastern area, and 13.9% in Midwestern area. The result implied that there were significant differences for both of them (between Northern area and Southern area χ2 = 117.1, P < 0.001 and between Eastern area and Midwestern area χ2 = 5512.2, P < 0.001). In 2- to 15-year-old children, the prevalence of constipation in Hong Kong was 16.0% and that in Chinese Mainland was 4.6%. There were significant differences between them (χ2 = 711.2, P < 0.001). The prevalence rates were 4.7% in Northern area, 4.0% in Southern area, 4.8% in Eastern area, and 4.9% in Midwestern area. There were no significant differences between Northern and Southern area (χ2 = 2.1, P = 0.15), as well as between Eastern and Midwestern area (χ2 = 0.15, P = 0.7) (Figure 2).
