title: [Growth status of children under 7 years in Wuzhong City, Ningxia Hui Autonomous Region, China and its influential factors].
abstract: OBJECTIVE
  To investigate the growth status of children under 7 years in Wuzhong City, Ningxia Hui Autonomous Region, China and its influential factors, and to provide a basis for related intervention measures.
  
  
  METHODS
  Children under 7 years were selected from two county-level districts in Wuzhong by stratified cluster sampling, and their growth status were evaluated by the Z score method.
  
  
  RESULTS
  The prevalence rates of growth retardation, underweight, and wasting were 12.58%, 5.71%, and 5.55% respectively. The height-for-age Z score, weight-for-age Z score, and weight-for-height Z scores were -0.26±2.50, 0.29±4.54. and 0.65±3.02 respectively. There were significant differences in the prevalence rate of wasting among children of different ethnic groups (P<0.05); also, there were significant differences in the prevalence rates of growth retardation and underweight among children from different regions and with different age (P<0.05). The main influential factors for growth retardation were region (OR=0.369, P<0.001), ethnic groups (OR=1.694, P=0.027), and age (OR=1.143, P=0.002). The main influential factors for underweight were region (OR=0.453, P=0.001) and age (OR=1.204，P=0.002). The main influential factor for wasting was nation (OR=1.735, P=0.024).
  
  
  CONCLUSIONS
  In Wuzhong, children under 7 years have poor growth status, which are related to ethnic groups, region, and age.
