Abstract: Objective To analyze prevalence and determinants of suspect developmental delay (SDD) in Warning Sign for Children Mental and Behavioral Development (WSC-MBD) checklist screening among children under 3 years old in rural China,so as to provide evidence for resource allocation for referral and intervention services,as well as the prevention strategy development. Methods A community based cross-sectional study was conducted from July to September 2016 in two poverty counties in Guizhou and Shanxi provinces separately. Cluster sampling by village was used to select children aged <3 years old and ≥ 3 months old. Age appropriate WSC-MBD was used by face-to-face interview with caregivers of children to detect SDD. Chi-square test and Logistic regression were used to examine the determinants of SDD. Results Total 1 298 children were enrolled,of whom 89(6.9%) children were preterm infants,341(26.3%) children with per capita net income of family less than 2 300 RMB/year,and 559(43.1%) were left-behind. Among all children,126(9.7%) children were detected with SDD,although 71.4% of SDDs were mild with only one abnormal warning sign out of 4 signs in total. Both the univariate and multivariate analysis suggested preterm birth was associated with higher risk of SDD (adjusted OR=2.193,95%CI:1.225-3.927). The prevalence of SDD deceased along with the increase of month age within the same WSC-MBD group (adjusted OR=0.823,95%CI:0.701-0.967). Conclusions WSC-MBD is feasible to detect SDD among children in rural China. The risk of SDD is associated with preterm birth,and sensitive to the small month age difference within the same WSC-MBD group.
