Abstract: Objective To explore the relationship between mental health, social support and suicidal ideation among overweight and obese adolescents, and to provide guidance for promoting the mental health development of overweight and obese adolescents and reducing the detection rate of suicidal ideation. Methods From April to March 2018,4 250 adolescents in Weifang City were selected and investigated using the Suicide Self-Assessment Scale (SIOSS), the Mental Health Self-Assessment Scale (K10), and the Social Support Scale (SSRS). Results The overweight detection rate of adolescents was 9.55% (406/4 250), and the detection rate of obesity was 6.94% (295/4 250).The mental health scores of rural overweight and obese adolescents were significantly higher than those of urban adolescents(P<0.001).The social support scores of urban overweight and obese adolescents were significantly higher than those of urban adolescents(P<0.001).In rural areas, the scores of suicidal ideation among overweight and obese adolescents were significantly higher than those in urban areas; Mental health and suicidal ideation were significantly positively correlated(r=0.639, P<0.01), and social support was significantly negatively correlated with mental health and suicidal ideation (r=-0.378 and -0.449, P<0.01); Mental health and social support had significant predictive effects on suicidal ideation in overweight and obese adolescents (β=0.278 and -0.197, P<0.01; R²=0.459), and social support played a partial intermediary role between mental health and suicidal ideation. Conclusion By improving their mental health status and improving the social support of overweight and obese adolescents, the suicidal ideation of overweight and obese adolescents can be reduced.
