RESUMO
Objective@#To explore the relationship between parental labour migration and preschool children’s physical health in poor rural areas,and to provide a scientcfic basis for the development of children’s education and public health in poor rural areas of China.@*Methods@#Using multi-stage stratified random cluster sampling method, this study investigated the physical health of 497 preschool children in six rural kindergartens in Cheng County, Longnan City of Gansu Province.@*Results@#The results showed poor physical health among preschool children, and two-week prevalence rate of respiratory system was 46.1%, two-week prevalence rate of diarrhea system was 14.5%. Parental out-migration significantly affects the prevalence of diarrhea in children, but not the prevalence of respiratory disease. For younger children, parental labour migration was associated with higher risk of physical health. Children’s active hand washing habits could significantly reduce the two-week prevalence of disease and associated with higher level of physical health(OR=1.97, 2.20).@*Conclusion@#Preschool children’s physical health is closely related to parental labour migration. Healthy habits should be encouraged to improve physical status among those children.
