ObjectiveTo analyze the current status of anxiety/depression and the influencing factors in junior high school students in Nanqiao Town， and to provide the objective evidence for relevant departments to promote the mental health of junior high school students.

MethodsThe stratified cluster sampling was used in this study. A total of 1 154 junior high school students from 4 out of 7 schools in Nanqiao Town were selected to participate in the survey. A self-designed questionnaire was used to collect basic information. The Chinese Middle School Students Anxiety Scale and the Chinese Middle School Students Depression Scale were used to assess anxiety and depression.

ResultsThe detection rates of anxiety and depression in junior high school students in Nanqiao Town were 27.3%（298/1 092） and 12.6%（138/1 092）， respectively. The detection rates of anxiety and depression in boys were 25.9%（147/568） and 12.2%（69/568）， respectively， while the rates in girls were 28.8%（151/524） and 13.2%（69/524）. There was no statistical difference between genders （χ²= 1.184，0.257， All P<0.05）. With gradual increase in grade， the detection rate of depressive symptoms also gradually increased （χ²=12.393，P<0.05）. Multivariate logistic regression analysis showed that the independent factors of anxiety were： foreign household registration （OR=2.2）， low learning interest （OR=3.8）， self-perceived learning pressure （OR=14.5） or moderate learning pressure （OR=3.8）， average personality （OR=1.5）， poor relationship with parents （OR=2.2）， and normal relationship with family （OR=2.0）. The independent influencing factors of depression included： moderate learning interest （OR=2.8） or low （OR=11.1）， self-consciousness high learning pressure （OR=4.1）， average personality （OR=1.9）， average relationship with family members （OR=2.0） or poor relationship with family members （OR=6.5）， and poor relationship with classmates and friends （OR=10.4）.
