abstract: OBJECTIVE
  To understand the health risk behaviors status and influence factors of Tujia and Miao adolescents in Xiangxi Area.
  
  
  METHODS
  By the method of layered, random and total sampling, questionnaire survey about dietary bias, current smoking, current drinking, suicidal ideation, internet addiction and lack of physical exercise was taken to 2094 Tujia and Miao adolescents. Logistic regression analysis was used to analyze the risk factors of health risk behaviors. Results The report rates of dietary bias, current smoking, current drinking, suicidal ideation, internet addiction and lack of physical exercise were 27. 84%, 18. 29%, 28. 03%, 21. 68%, 5. 25% and 52. 82%, respectively. Logistic regression analysis result showed that the risk factor of dietary bias was depression(OR = 1. 352, P =0. 026), the protective factor were schoolboy (OR =0.765, P=0.008) and in residence(OR =0.743, P =0.004). The risk factor of current smoking were schoolboy (OR =6. 782, P =0. 000), insomnia(seldom or sometimes OR = 1. 516, P = 0. 013, often or always OR = 2. 738, P = 0. 000), internet addiction (OR =2.389, P =0. 000), fight(OR = 2. 481, P = 0. 000) and current drinking(OR = 4. 060, P = 0. 000), the protective factor was school record (average OR = 0. 699, P = 0. 026, above average or good OR = 0. 437, P = 0. 000). The risk factor of current drinking were schoolboy (OR = 1. 829, P = 0. 000), insomnia (seldom or sometimes OR = 1. 550, P = 0. 002, often or always OR = 1. 754, P = 0. 004), internet addiction (OR = 1. 901, P =0. 004), fight (OR = l.785, P = 0. 000)and current smoking (OR = 4. 016, P = 0. 000). The risk factor of suicidal ideation were lonely(seldom or sometimes OR = 1. 823, P =0. 010, often or always OR = 4. 445, P =0. 000), depression (OR = 3. 226, P = 0. 000) and only child (OR = 1. 612, P = 0. 003), the protective factor was schoolboy (OR =0. 648, P = 0. 000). The risk factor of internet addiction were schoolboy (OR = 2. 480, P = 0. 000) depression (OR = 2. 650, P = 0. 000) and mainly to play games(OR = 4. 631, P = 0. 000). The risk factor of lack of physical exercise were high school student (OR = 1. 536, P =0. 000) and depression(OR = 1. 410, P = 0. 003), the protective factor were schoolboy (OR ='0. 581, P = 0. 000) and school record (average OR = 0. 798, P = 0. 036, above average or good OR = 0. 609, P = 0. 000.
  
  
  CONCLUSIONS
  Tujia and Miao boys were more prone to smoking and drinking behavior, while girls were likely to happen dietary bias, suicidal ideation and lack of physical exercise behavior. Miao students were high-risk population of smoking and drinking behavior. Insomnia and depression became risk factors of multiple health risk behaviors.
