Abstract: ObjectiveTo investigate the current status of health-related behaviors and their influencing factors among preschool children in Longhua District, Shenzhen.MethodsA survey was conducted to investigate the health-related behaviors among preschool children of the kindergartens in Longhua District, Shenzhen and the cognition and practices of parents on training children’s health-related behaviors. Multivariable linear regression was used to analyze the relationships between scores of preschool children’s health-related behaviors and gender, household registration, only child or not, grade, parental education level, the cognition and the practices of parents on training children’s health-related behaviors.ResultsA total of 62 922 preschool children were surveyed. Of them, 54.5% were boys, 45.5% were girls; 23.7% were in primary class, 35.1% in middle class, 41.2% in top class; 30.4% had Shenzhen household registrations and 69.6% did not. The correctness percentages of performing 32 health-related behaviors were between 12.2% and 98.0%. Among 6 dietary behaviors, 98.0% of the children performed correctly in “less intake of fried foods”, while 58.8%preformed correctly in “not playing while eating”. Among 12 health behaviors, 89.1% of the children performed correctly in “not shitting everywhere”, while only 12.2% preformed correctly in “gargling after meals”. Among 11 safety behaviors, 96.5% of the children performed correctly in “not playing with fire”, while 40.3% preformed correctly in “walking up and down stairs slowly on the right”. Among 3 resting and recreation behaviors, 64.8% of the children performed correctly in “watching TV/computer for less than 1h”, while 33.5% preformed correctly in “going to bed early and getting up early”. Multivariable linear regression showed that the scores of preschool children’s health-related behaviors were related to children's gender, household registration, grade, educational background of the parents, the cognition and practices of parents on training children’s health-related behaviors.ConclusionSome health-related behaviors among preschool children in Longhua District, Shenzhen need to be improved.
