Logistic regression analysis result showed that the risk factors of current smoking were schoolboy (OR = 9. 765, P = 0. 000) and suicidal ideation (OR = 2. 139, P = 0. 000), the protective factors were city(OR = 0. 678, P = 0. 020)and school record (average OR = 0. 580, P = 0. 003,above average or good OR = 0. 477, P = 0. 002). The risk factors of current drinking were senior school (OR = 1. 438, P = 0. 005 ), Tujia (OR = 1. 784, P = 0. 000), mother' s degree of education(junior or senior school OR = 1. 330, P = 0. 045, college and above OR = 2. 938, P = 0. 000), depression (OR = 1. 570, P = 0. 004)and fight (OR = 1. 755, P =0. 000), the protective factor was school record (above average or good OR = 0. 646, P = 0. 019). The risk factors of smoking-drinking at the same were schoolboy (OR = 7. 246, P = 0. 000), left-behind children (OR = 1. 412, P = 0. 023), lonely (seldom or sometimes OR = 1. 646, P = 0. 030, often or always OR = 2. 193, P = 0. 006), insomnia (often or always OR = 2. 396, P = 0. 001), depression (OR = 1. 552, P =0. 018), fight (OR = 3. 432, P = 0. 000)and suicidal ideation (OR = 1. 918, P = 0. 001),the protective factors were in dad mood (seldom or sometimes OR = 0. 362, P = 0. 000, often or always OR = 0. 386, P =0. 001) and school record (average OR =0. 587, P =0. 001, above average or good OR = 0. 354, P =0. 000).
