  1. Model 3b controlled for demographic characteristics (except ethnicity variable, which was not correlated with SRH in univariate analysis) and socio-economic status factors
  2. Model 4b also controlled lifestyle factors in addition to the factors controlled in model 3b
  3. Model 5b also controlled for psychosocial factors in addition to the factors controlled in model 3b
  4. OR odds ratio, 95% CI 95% Confidence Intervals
  5. ***p < 0.01, **p < 0.05, *p < 0.1
  6. Note:
  7. Data were from the Chinese General Social Survey (2010). The structure of the questionnaire in 2010 is similar to that in 2013
  8. Since only 3,337 respondents reported smoking habit, so the data from these 3,337 respondents were complete
  9. “Two subjective socio-economic status” variables and “Relationship with families and friends” can not be obtained from the dataset 2010. But we add “Smoking habit” variable (Yes = 1 No = 0) in the analysis
