for categorical variables was produced to determine factors associated with substance use, Odds 
ratio with a 95% confidence interval was calculated to measure the strength of association 
between dependent and independent variables. To ascertain the association; variables found to be 
significant (p-value<=0.25) in the bivariate analysis was used to construct a multivariable model. 
Multivariate logistic regression analysis was done to control possible confounders and to 
determine factors that may be significantly associated with substance use. For multivariable 
analysis statistical significance was considered with two side‟s p-value of 0.05.
