[The prevalence rate and influencing factors of cough in children under 5 years old in Yiwu city, Zhejiang Province in 2019].

ABSTRACT

Objectives: To investigate the prevalence of cough and its influencing factors in community children under 5 years old. Methods: From October to December 2019, we selected 3 102 community children under the age of 5 from 50 natural villages/residential communities in 14 towns/streets of Yiwu, Zhejiang Province, using multi-stage random sampling method. A face-to-face and on-site questionnaire survey was conducted among child caregivers to collect demographic data and information about children's cough in the last 1 month. Multiple logistic regression model was used to analyze children's cough and the influencing factors of different cough states. Results: Multivariate logistic regression model analysis results showed that compared with 0-1 year old, dispersed, caregivers with education level below high school, families with 1 child under 5 years old, Cough risk was higher in 1-2, 2-3, 3-4 years old, nurseries, caregivers with education level of high school or above, and families with more than 2 children under 5 years old. OR (95%CI) values were 1.52(1.19-1.92), 1.65(1.29-2.10), 1.86(1.36-2.54), 2.59(1.99-3.38), 1.48(1.26-1.74) and 1.35(1.13-1.62), respectively. Further analysis of the influencing factors of different states of cough, multivariate logistic regression model analysis results showed that preschool status, the number of children under 5 years old in the family and the education level of caregivers were the influencing factors of acute, prolonged and chronic cough. Age was only an influencing factor of acute and persistent cough. Conclusions: The disease burden of cough in children under 5 years old community was heavy, and the cough was related to children's age, education level of caregivers, number of children under 5 years old in the family and childcare status.
