Abstract: 【Objective】 To understand stunting status and explore the influence factor of stunting. 【Methods】 A cross-sectional method to examine 1 031 pupils aged 9 to 12 years. These pupils came from 15 schools in Guangxi Autonomous Regional and Hainan Province rural areas in China. Study contects included questionnaires survey; physical examination, based on the new WHO Child Growth Standards(WHO Anthroplus, 2007); haemoglobin detection; stool samples were examined by Kato-Katz technique to choose soil-transmitted helminthes (Hookworm, Ascaris lumbricoides and Trichuris trichiura) infections. EpiData3.0 was used to establish a database. Statistical analyses of the data were performed using statistical package for Social Sciences for Windows SPSS(version 16.0). 【Results】 The overall prevalence of stunting (HAZ<2SD) was 25.6% (264/1 031). Risk factors for stunting that based on logistic regression analyses were: 1) Soil-transmitted helminthes moderate-to-heavy intensity infections(OR=1.927,95%CI:1.194~3.110); 2)anaemia(OR=3.26,95%CI: 2.018~5.268); 3)education level of mother(OR=2.125,95%CI:1.388~3.254).The overall prevalence of STH infections was 36.7% (378/1 031),moderate-to-heavy intensity STH infections was 16.8%(173/1 031). Ascariasis, hookworm trichuriasis and co-infection were 11.2%(115/1 031),11.5%(119/1 031),4.9%(51/1 031), and 9.1%(93/1 031) respectively. The anaemia (Hb<120 g/L) was 13.1%. 【Conclusions】 The present study shows that stunting is highly prevalence among study population and STH infections is one of the important risk factors for stunting, especially moderate-to-heavy intensity infections is the main predictors of stunting.
