The investigation was conducted based on " The scale and evaluation method of health related/risk behaviors for adolescents in China". To analyze the behaviors on dietary bias, lack of physical exercise, suicidal ideation, smoking, drinking and internet addiction.

Logistic regression analysis result showed that the risk factors of dietary bias were schoolgirl( OR = 1. 275, P = 0. 012), lack of physical exercise( OR = 1. 751, P < 0. 001), depression( OR = 1. 297, P = 0. 046), suicidal ideation( OR= 1. 280, P = 0. 036) and internet addiction( OR = 1. 753, P = 0. 001). The risk factors of lack of physical exercise were high school( OR = 1. 839, P < 0. 001), schoolgirl( OR =1. 478, P < 0. 001), nuclear family( OR = 1. 240, P = 0. 034) and dietary bias( OR =1. 717, P < 0. 001). The risk factors of suicidal ideation were schoolgirl( OR = 1. 789, P< 0. 001), only child( OR = 1. 452, P = 0. 030), fight( OR = 1. 894, P < 0. 001), lonely( often or always OR = 4. 484, P < 0. 001), insomnia( often or always OR = 2. 392, P <0. 001), depression( OR = 2. 555, P < 0. 001) and internet addiction( OR = 1. 766, P =0. 004), the protective factor was in residence( OR = 0. 755, P = 0. 029). The risk factors of smoking were in residence( OR = 1. 638, P = 0. 004), fight( OR = 2. 315, P < 0. 001), insomnia( often or always OR = 2. 116, P = 0. 004) and drinking( OR = 5. 456, P < 0. 001), the protective factor were schoolgirl( OR = 0. 132, P < 0. 001) and school record( above average or good OR = 0. 571, P = 0. 004). The risk factors of drinking were total monthly income of family( above 3000 yuan OR = 1. 648, P = 0. 015), fight( OR = 1. 990, P < 0. 001), suicidal ideation( OR = 1. 363, P = 0. 019), smoking( OR = 5. 351, P < 0. 001) and internet addiction( OR = 1. 797, P = 0. 002), the protective factor was schoolgirl( OR = 0. 459, P <0. 001). The risk factors of internet addiction were dietary bias( OR = 1. 812, P = 0. 001), suicidal ideation( OR = 1. 843, P = 0. 002), lonely( often or always OR = 3. 029, P = 0. 003), drinking( OR = 2. 028, P < 0. 001) and mainly to play games( OR = 3. 650, P < 0. 001).

CONCLUSION

The Dong and Bai Nationality boys are more prone to smoking、drinking and internet addiction behaviors, while girls were likely to happen dietary bias, lack of physical exercise and suicidal ideation. Insomnia and unhealthy psychology such as lonely and depression become risk factors of multiple health risk behaviors. The combined action should be carried out in order to prevent and intervene the health risk behaviors of Dong and Bai Nationality rural adolescents.
