%X This research seeks to explore the occurrence rates of smartphone dependency, levels of exercise, and signs of depression in middle school pupils, while assessing the interactive influence of smartphone dependency and exercise on depression indicators. Cluster sampling was applied across two middle schools located in Shanghai's Jing’an District, China. Single-variable comparisons examined differences in depression indicator rates according to various participant traits. Multiple logistic regression models evaluated links between smartphone dependency, exercise habits, and their interactive influence on depression indicators.

The survey included 1,316 valid participants, revealing occurrence rates of depression indicators (36.2%), smartphone dependency (19.2%), and low exercise engagement (23.3%).
