Association between parental education level and time spent outdoors among children/
Objective To explore the association between parental education level and time spent outdoors among children,so as to provide the scientific evidence for formulating policies of myopia prevention and control among children.Methods The study was based on secondary analysis of data from outdoor intervention studies in Shanghai.The follow-up period was from March to De-cember 2018.It included control group children(n=1 117)with complete questionnaire surveys,ocular examinations,and time spent outdoors.Generalized linear regression models and trend tests were used to analyze the effect of parental education level on time spent outdoors among children.Results The median time spent outdoors was 76.4(59.7,94.6)minutes.After adjusting for covariates including children's sex and age,generalized linear regression model suggested that there was no statistical significance between father's education level and outdoor activity time(P＞0.05).Compared with children whose mothers had a junior high school education or below,children whose mothers had high school/vocational high school education,college or above had shorter time spent outdoors(β=-6.64,-8.84,P＜0.05).Trend tests revealed that time spent outdoors among children decreased with the increase of parental education level(Ptrend＜0.01).Conclusions The higher the education level of fathers or mothers,the shorter time spent outdoors of children.In addition to highlight outdoor activities at school,myopia prevention and control efforts should be focused on the role of parents in increasing children's outdoor activities.
