Outline
To study the effects of green space exposure combined with outdoor exercise duration on negative emotions (depression, anxiety and stress) among primary and secondary school students in Jiangsu Province.
A total of 19 903 primary and secondary school students in Jiangsus Province who met the criteria were randomly selected for inclusion in this study. Through the questionnaire survey, the demographic data of the research subjects and the information of negative emotions were collected. The annual average value of the Normalized Vegetation Index (NDVI) of the school environment of the study subjects was used as the spatial measurement of green space. A logistic regression model was used to evaluate the association between green space exposure and outdoor exercise duration and negative emotions.
The detection rates of depression, anxiety and stress were 13.2% (2 631), 21.9% (4 367) and 9.7% (1 927) of the 19 903 participants, respectively. The range of NDVI is (0.19, 0.52); The correlation between green space exposure and outdoor exercise duration, individually or in combination, and the detection rate of negative emotions was generally similar in both regional and gender subgroups.
Expanding the exposure of green space and increasing the time of outdoor exercise can help alleviate the negative emotions of primary and secondary school students, and the research on green space exposure can provide effective measures for school health and psychological services.
