Abstract
OBJECTIVE: The aim of this study was to explore the prevalence of and the risk factors for subjective symptoms without an identified cause by the guardian (SSWICG) in urban preschool children. METHODS: A questionnaire was used to collect information from 661 urban preschool children. The subjective symptoms were cited from the MM075NA Indoor Environment Quality Investigation Questionnaire. Information about living conditions, kindergarten and outdoor environments was collected, as well as health information from each child. RESULTS: The prevalence of SSWICG reached 31%, among which the prevalence of general symptoms in the central nervous system (CNS) reached 54.6%. Univariate analysis showed that the materials that made indoor furniture, walls and doors, indoor biological factors, outdoor pollution sources near the house and traffic pollution were associated with SSWICG and mucosal, dermal and general symptoms in the CNS subgroups. Multivariate analysis also showed that furniture materials, traffic pollution, kindergarten environment quality and allergies were associated. CONCLUSIONS: The prevalence of SSWICG was relatively high. Possible risk factors include indoor furnishing materials, allergy, traffic pollution and kindergarten environmental pollution.
