Bayesian Logistic Regression Analysis of the Association of Intimate Partner Violence and Modern Contraceptive Use in the Philippines

This study employs data extracted from the 2008 Philippine National Demographic and Health Survey to examine the association between intimate partner violence and modern contraceptive use among married women in the Philippines. Instead of the classical approach of data analysis commonly used in many studies, the Bayesian approach for logistic regression analysis is used to estimate the association between intimate partner violence and modern contraceptive use. Important variables that can affect the association such as the woman’s age, work status, education, place of residence and religion, the husband’s education and work status, the household’s wealth status, family size, and decision making control were considered in this study. This study revealed a significant association between intimate partner violence and modern contraceptive use with an odds ratio of 1.345 and a corresponding 90% credible interval of 1.201 to 1.502. Thus, the odds of using modern contraceptives for married women in the Philippines who had experienced intimate partner violence is 34.5% higher than the odds for those women who did not experience intimate partner violence.
