ABSTRACT=<p>Douyin is the Chinese version of TikTok. Using Douyin at bedtime is a very common behavior among Douyin users. However, the reasons why users like using Douyin before sleep are yet unclear. We conducted a cross-section survey from January 1st to January 16th, 2023 to capture data to examine the associations of depression, anxiety, life satisfaction, well-being, loneliness, and physical activity with Douyin usage at bedtime. The mediation role of insomnia in these associations was examined. A total of 3,392 participants who met the inclusion criteria were included for analysis. Our structural equation modeling analysis showed that depression on (<italic>β</italic> = 0.08; <italic>p</italic> &lt; 0.05), anxiety (<italic>β</italic> = 0.06; <italic>p</italic> &lt; 0.05), and loneliness (<italic>β</italic> = 0.14; <italic>p</italic> &lt; 0.05) were directly associated with increased Douyin usage at bedtime, and were also indirectly associated with Douyin usage through insomnia (depression: <italic>β</italic> = 0.18; <italic>p</italic> &lt; 0.05, anxiety: <italic>β</italic> = 0.16; <italic>p</italic> &lt; 0.05, and loneliness: <italic>β</italic> = 0.12; <italic>p</italic> &lt; 0.05). Life satisfaction (<italic>β</italic> = −0.05; <italic>p</italic> &lt; 0.05) and well-being (<italic>β</italic> = −0.20; <italic>p</italic> &lt; 0.05) were directly associated with decreased Douyin usage at bedtime, and were also indirectly associated with Douyin usage through insomnia (life satisfaction: <italic>β</italic> = −0.09; <italic>p</italic> &lt; 0.05, and well-being: <italic>β</italic> = −0.11; <italic>p</italic> &lt; 0.05). However, physical activity was unexpectedly associated with increased Douyin usage at bedtime (<italic>β</italic> = 0.20; <italic>p</italic> &lt; 0.05). In conclusion, our findings shed new light on the specific reasons why Douyin users like using Douyin at bedtime.</p>
