Magister Public Health - MPH / Background: The HIV / AIDS pandemic have been characterized as the greatest natural challenge ever to confront humanity and one of the great moral causes of our time (World Bank, 2007). Although, the HIV and AIDS pandemic is a global problem, some regions of the world, notably sub-Saharan Africa are hardly hit by the pandemic. Namibia is one of the sub-Saharan African countries which are badly affected by the HIV and AIDS pandemic. It is estimated that about 360 000 Namibians were infected with HIV by 2010. This translates to a national HIV prevalence of (18.8%). The National HIV and AIDS Response Department has designed various interventions and strategies to curb the spread of the HIV. Promotion of male condoms promotion is one of the key strategies being advocated. If used consistently and correctly, male condoms are regarded as an effective preventive tool of HIV transmission. However, changing individual’s sexual behaviors and lifestyle to make condom use part of their sexual life seems to be the challenge. In Namibia most of the research in the area of HIV and AIDS were done among the youth and population aged between 15 – 49 years. Hence, this study looks at older men as a neglected population. Aim: The aim of the current study was to assess knowledge, attitudes and practices of condom use among male employees age 50 (fifty) years and older at a mining company in Southern Namibia. Methodology: A descriptive, cross-sectional survey utilizing quantitative research approach was applied. Data was collected through face-to-face interviewing male employees, age fifty years and older, while at work at the Mine Area 1 (MA1). Data was captured in excel and imported into SPSS version 16.0. Chi-square test was used to determine the association between KAP variables and the socio-demographic characteristics of the respondents. The level of statistical significance was set at 0.05. Results: Among 105 respondents (males, mean age 54.5 years), more than half lived in the singe sex male hostels. Knowledge about condom use was good but there remained a significant number of the respondents whose knowledge was insufficient. A high percentage of the respondents suggested that HIV positive individuals should always use condom every time they have sexual intercourse. Conclusion: This study showed that respondents are not at a high risk of contracting HIV infection due to lack of knowledge on condom use though some of them possessed insufficient knowledge. Thus, to minimize the likelihood of HIV infection targeted interventions including peer education programmes were suggested, and working with the community in the area. Moreover, a more comprehensive knowledge attitude and practice study among mine employees from various sections of the mine would be beneficial to identify the level of risk within the total employee population.

Increased awareness of protection against infections such as Hepatitis Band Human Immune-deficiency Virus (HIV)/ Acquired Immune Deficiency Syndrome (AIDS) and other sexually transmitted diseases has led to an increase in the demand for latex gloves and condoms leading to an increase in latex allergy. Besides latex, condoms also contain several undisclosed chemicals including antioxidants, accelerators, emulsifiers, stabilizers, lubricants, and in some cases flavourings and colourants. Though extensive testing is done to evaluate the physical quality of condoms, little information is available regarding the biological safety of condoms. In this study a modification of the direct cell culture testing method that is specified by the American Test Method F813-83 of 1998 was used to determine the cytotoxicity of the surface material of latex condoms prepared at time intervals that represents normal physiological exposure times T2, T4 and T8. The L929 cells were exposed to medium containing increasing amounts of condom washings (0-66%) for 20 hours. After exposure cell number and viability was determined using the Crystal violet (CV) and 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-3H-tetrazolium bromide (MTI) assays respectively. Data was evaluated using a split-plot design with the appropriate Analysis of Variance (ANOVA). The effect of the condom washings on cell morphology and CV staining, MTI metabolism and Neutral red (NR) uptake at a fixed condom washing (16%) and exposure time T8 was evaluated microscopically. Cell membrane integrity was evaluated by Propidium iodide (PI) uptake and with PI staining after fixation and Hoechst 33324 (H33342) staining nuclear structure was evaluated with fluorescence microscopy. Apoptosis induced DNA fragmentation was evaluated by agarose gel electrophoresis. The effects of condom washings at 16% condom washing and exposure times T2, T4 and T8 was further evaluated in the HeLa cell line, a cell line in origin and type closer to that of the cervical lining. Cytotoxicity was evaluated using the CV, MTT and NR assays. In the L929 cell line, condom types Non-lubricated condoms (NLC), Lubricated condoms (LC) and Lubricated and flavoured condoms (LFC) behaved differently over time of exposure and the concentrations of condom washings. LFC were found to induce a decrease in cell number compared to other condom types, followed by LC and NLC revealed increases in cell number. Split-plot analysis, revealed that condom type x time (CT x Time) is significantly different due to the effect observed at T2 for LC. The MTT usually considered being more sensitive than the CV assay showed only toxicity for LFC and not for NLC and LC as with the CV assay. Exposure to LFC revealed significant decrease of 70 % decrease in cell viability at T8. Condom washings, LC, LFC and LFCC had no effect on cell morphology following CV staining. MTT metabolism and NR uptake was reduced and altered cell morphology was observed for L929 cells exposed to LFC and LFCC. Little PI uptake was observed for all cells exposed to condom washings. Condensed nuclei were observed for L929 cells exposed to LFC and LFCC while Hoechst staining revealed peripheral arrangement of DNA with Hoechst 33342 staining. Cell death in L929 cells were found to be mediated by apoptosis with L929 exposed to LFC showing the most damage. All effects of LFC is greater than that observed for LFCC indicating that other factors rather than the number of components present in each type of condom may account for toxicity. Toxicity of condom washings were compared to that found in the L929 cell line using the CV and MTT assays and an additional bioassay the NR assay was included. Condom types, LC, LFC and LFCC had a significant effect on cell viability and lysosomal membrane integrity. Differences observed between the L929 and HeLa cells were due to the increased viability observed for LC and the decrease in membrane integrity for LFC on HeLa cells. With LC and LFC no decrease in cell number and viability was observed as previously reported for the L929 cell line. Although no decreased in cell viability is observed for LFC a decrease of 75% in lysosomal membrane integrity is observed. The increase in cell viability found for HeLa exposed to LC (although statistically not significant) cannot be explained. Changes in cell viability and membrane integrity was only observed for HeLa cells, indicating that the HeLa cell line is more sensitive to the cytotoxic effects of condom washings. Furthermore the NR assay is a more sensitive assay than the MTT assay in detecting the cytotoxic effects of LFC condom washings at low concentrations. These are assays address only the effects of short-term exposure and not possible genotoxic effects that may occur following repeated and long-term exposure as reported in other latex products. / Dissertation (MSc (Anatomy))--University of Pretoria, 2006. / Anatomy / unrestricted

Infection with the human immunodeficiency virus (HIV) in the adolescent/young adult population of the United States is a serious, growing problem. The current HIV risk-reduction strategies for adolescents have been less than effective in stemming the tide of infection. This ineffectiveness can be linked to failure of making developmentally appropriate risk-reduction informational material and reliance on condom-based interventions, which have an unacceptably high failure rate. A critical analysis of current models of HIV-risk reduction should be undertaken to create more developmentally appropriate and effective methods.

The purpose of this study was to assess male college students’ use of condoms, reasons for using condoms, their attitudes toward sexuality, and their attitudes toward condoms. The sample consisted of 305 male students who completed a questionnaire consisting of informational items (assessing class standing, marital status, reasons for using condoms, number of recent sexual partners, and intention to use condoms), the Sexual Opinion Survey, and the Attitude Toward Condoms Scale. The scores on the Attitude Toward Condoms Scale ranged from extremely negative to extremely positive, but the mean was close to the middle of the scale. The item correlation between the Attitude Toward Condoms Scale and the Sexual Opinion Survey was calculated to be .07 or no correlation, this implies there is no relationship between attitude toward sexuality and attitude toward condoms. A mild negative correlation (-.42) was noted between the Attitude Toward Condoms Scale and the item that stated "If you have intercourse in the next month, do you intend to use condoms?" The implications of these findings for increasing condom usage and recommendations for future research were discussed. / Master of Science
