Effect Of Neighborhood Environment On Physical Activity In Urban Youth

Purpose:To investigate the physical activity,neighborhood environmental factors and their sociological characteristics of urban youth in the past 7 days,we analyzed the influence of neighborhood environmental factors and sociological characteristics on physical activity of urban youth,and it provides a reference for the development of physical activity promotion strategiesMethod:From May to September in 2019,the young people in Jinan,Weifang,Linyi and other urban areas were selected as the subjects by cluster sampling.Using the new-a to investigate the components of neighborhood environment which included service availability,Community streets,walking and cycling lanes,community beautification,traffic risks and community safety;Using the international physical activity questionnaire(IPAQ)to investigate physical activity,and collect the basic demographic characteristics of the respondents.Spss20.0 was used for statistical analysis,and one-way ANOVA was used to analyze the differences of neighborhood environment scores among urban youth groups with different physical activity levels Pearson analyzed the relationship between neighborhood environmental factors and physical activity.Cluster analysis of urban youth neighborhood environment factors scores.The related variables were included in the stepwise regression equation to analyze the influence of the variables on the total physical activity of 7 days.The weight coefficient was used to analyze the determinants of neighborhood environmental factors(service availability,Community streets,walking and cycling lanes,community beautification,traffic risks and community safety)on physical activity of urban youthResults:A total of 1900 questionnaires were distributed and 1271 questionnaires were effectively recovered.The average age of the respondents was 33.73±3.93 years old,of which 32.7%of the urban youth had low level of physical activity,29.2%had medium level of physical activity and 38.1%had high level of physical activity Compared with the urban youth with low level of physical activity,the youth with middle and high level of physical activity scored higher in the service availability,walking and cycling lanes,environmental beautification and community safety factors Pearson correlation analysis showed that there was a significant positive correlation between the total physical activity of urban youth in 7 days and their community service availability,walking and cycling lanes,environmental beautification and community safety scores(P<0.05).There was a negative correlation with their educational level and gender(P<0.05).Further cluster analysis was conducted on the total physical activity of urban youth in seven days.The scores of community service availability,Community streets,walking and cycling lanes,community beautification,traffic risk and community safety of urban youth with high physical activity in seven days were higher than those of the group with low physical activity in seven days Through regression analysis,the physical activity of urban youth is related to their gender,education level,service availability,environmental beautification and community safety.Through the weight coefficient analysis of service availability,environmental beautification and community safety environmental factors,it is found that the distance from bus,convenient neighborhood environment and total physical activity of urban youth in seven days has an important impact on service availability In terms of environmental beautification,when walking near the residence,you can see interesting things,which have the largest weight coefficient for the physical activity of urban youth.In terms of community safety,the crime rate near the place of residence has the greatest impact on physical activityConclusion:Among the elements of neighborhood environment,the most important factors which affect physical activity of urban youth are the convenience of community from bus and other stations,the interesting things we can see during walking,and community crime rate.Sociological factors such as gender and education level are also related to the physical activity of urban youth.
