- Description: The effects of gender and age on the behavioral risk of HIV/AIDS are not clearly understood as previous distinct studies which have been carried out, have given disputable and contradictory outcomes. This study therefore, discusses the statistical methods which can be used to model the influence of age and gender on the behavioral risk factors of HIV/AIDS. In general, generalized linear models are the main methods which can be applied to depict the impact of age and gender on the behavioral risk of becoming infected with HIV/AIDS virus. In this study, the main methods used were logistic regression, log-linear regression and multiple regressions. Behavioral risk was taken as the dependent variable while age, gender, number of sexual partners, religious beliefs and alcohol and drug abuse were fitted as predictor variables. The three statistical methods gave significant results for gender and insignificant results for age. Furthermore, comparisons were made on the three regression methods and the logistic regression gave the best results. It was therefore concluded that gender plays a significant role on the behavioral risk of HIV/AIDS. The results of the study showed that gender of the student and number of sexual partners had a significant effect on the risk behavior of the university students. In future, it may be very important to find out why age is not a significant factor on risk behavior of HIV/AIDS among university students.

The right of the HIV/AIDS patient to treatment

- Description: The objective of this treatise is to establish whether a right to social security exists in South Africa, which would entitle HIV positive persons in South Africa citizens to medical care. A study was made of various articles in journals and on the Internet to determine the South African government's policy on a right to social security and to providing medical treatment. It was found that South Africa lacks an integrated, holistic approach to social security and does not guarantee the right to social security, merely the right to have access to social security. The same was found with the right to medical care. Although there seems to be a general right to medical care which extends to and includes HIV-positive patients, the state merely guarantees the right to apply for medical treatment but does not guarantee the granting thereof. It is submitted that the Department of Health's refusal to implement a vertical transmission prevention programme and the failure to offer treatment as an alternative, for whatever reason, is "penny wise and pound foolish". In the long run more money is spent dealing with pediatric AIDS. It was further found that although the government attempted to lay a groundwork with the formulation and acceptance of the national AIDS plan, the successful implementation thereof is seriously hindered due to the lack of inter- and intra-departmental collaboration, essential health services and funding.
