Logistic regression model was developed use by Truett et al. (1967), using
multivariate analysis in the Framingham heart study. Since then, the logistic
regression model has become a standard binary or dichotomous data analysis in
various areas of medicine.
Data was tabulated, cross tabulated and analyzed statistically using PASW version
18. A probability value of p < 0.05 was considered to be significant. Binary
logistic regression analysis was conducted with reporting of odds ratio to establish
the risk for hypertension. To explore the underlying association between
hypertension and the selected explanatory variables, a set of logistic regression
models is fitted in this section. Let define the following dichotomous variables for
the hypertension.
