  2. §This table illustrates two socio-demographic models that assess the independent effect of child’s birthplace on breastfeeding initiation and duration. First, each independent variable was assessed by univariate analyses individually. Unadjusted Odds Ratios (ORs) and P values were obtained. Second, variables having significant effect (P < 0.15) on the outcome were entered together in a logistic regression model. Child’s birthplace was entered in the model regardless of its significance. Child’s current age was also entered in the model regardless of its significance, to control for any time-related differences in breastfeeding. Adjusted ORs and P values were obtained. For continuous variables, it was indicated that when age increased one year, the odds of initiating breastfeeding / breastfeeding≥4 months would increase (OR-1) times
