A weighted bootstrap approach to logistic regression modelling in identifying risk behaviours associated with sexual activity

Abstract

The latest population estimates released by Statistics South Africa indicate that 25.03% of alldeaths in 2017 in South Africa were AIDS-related. Along with these results, it is also reportedthat 7.06% of the population were living with HIV, with the HIV-prevalence among youth(aged 15–24) at 4.64% for 2017 (STATSSA. (2018). Retrieved from Statistics South Africa:http://www.statssa.gov.za/publications/P0302/P03022017.pdf). The data used in the studycontained information related to the risk-taking behaviours associated with the sexualactivity of enteringfirst-year students at the University of the Western Cape. In this study, alogistic regression modelling procedure was carried out on those students that weredetermined to be sexually active, therefore, in the modelling procedure significant riskbehaviours of sexually activefirst-year students could be identified. Of the 14 variablesincluded in the modelling procedure, six were found to be significantly associated withsexually active students.
