Abstract: Objective To explore the prevalence and influencing factors of diarrhea in rural children under 7 years old in five counties of Ningxia Hui Autonomous region,in order to provide scientific references for taking corresponding intervention measures and optimally allocating of health resources. Methods Data of 10 318 rural children were collected by Health Survey Questionnaire on Rural Residents program performed collaboratively by Ningxia Health Bureau and Harvard/Oxford University Research Team in 2009,2011,2012 and 2015 in five counties (Haiyuan, Yanchi, Tongxin, Pengyang and Xiji) of Ningxia.Influencing factors of diarrhea in children were determined by unconditioned binary Logistic regression analysis. Results Totally 558(5.4%) rural children under 7 years old in five counties of Ningxia suffered from diarrhea over the last two weeks.Single factor analysis showed that children with different ages, nationalities and vaccine experiences had significantly different prevalence rates of diarrhea (P<0.05).Logistic regression analysis results showed that hui ethnic group (OR=1.351,95%CI:1.090-1.671), younger ages(0-＜2 years old OR=10.515,95%CI:7.308-15.129; 2-＜4 years old OR=3.319,95%CI:2.285-4.821) and low family income per year (OR=1.555,95%CI:1.229-1.966) were risk factors for childhood diarrhea in this area. Conclusions The prevalence rate of diarrhea in children under 7 years old in rural areas of Ningxia is still high.Nationality, age and family income may be the main influencing factors for childhood diarrhea.
