In Table 2, the results of the collinearity test show that the tolerance value of all variables was greater than 0.10. While the VIF value for all variables was less than 10.00. The basis for decision making in the multicollinearity test concludes that there were no symptoms of multicollinearity in the regression model.

Further results of the binary logistic regression test on pregancny readiness are available in Table 4. There were two independent variables tested at this stage: ethnicity and education level.
The results of the analysis in Table 4 inform that Madurese married female adolescents were 0.563 times more likely to be ready for pregancy than Javanese married female adolescents (OR 0.563; 95% CI 0.369–0.857). While no significant differences were found between the other ethnic groups and the Javanese group. Similarly, there were no significant differences between education levels.
