Introduction
Introduction years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

  • Young people are most affected and infected by HIV/AIDS pandemic especially in Sub-Sahara

    [Welz et al 2006; UNAIDS 2006]

  • Correct and consistent use of condoms is estimated to reduce HIV transmission by 80-90%

    [Pool et al 2006; Steiner, Cates 2006]

  • High HIV prevalence is associated with low condom use

    [Pettifor et al.2005; Gregson et al 2006]

  • Condom use rates among young adults are relatively low, have not nearly reached 100%

    [MacPhail, Campbell 2001]


Problem statement
Problem statement years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

  • In South Africa, condom use is low :

    • at last sex (12%) among females 15-49 yrs

      [Camlin, Chimbwete South African Demographic Health 1998 Data]

    • Ever using condoms on average (50%) among young adults

      [Pettifor et al 2005; Shisana et al 2002; Health Systems Trust 2004]

  • Knowledge about condoms and HIV prevention is high but general perception of risk to infection and vulnerability is low (70% believed that they were at no risk or low risk of HIV infection)  low condom use

    [Maharaj 2006; MacPhail, Campbell 2001]


Research question
Research question years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

  • What are the factors associated with condom use and its consistency of use among young adults aged 15-24 years in the Africa Centre Demographic Surveillance Area (ACDSA)?


Definition of terms
Definition of terms years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

Condom use

Proportion who reported ever using a condom with the most recent partner in the last year

Q. “Have you and your partner ever used a condom? (IF YES) How often do

you use condoms?” .

  • “sometimes” or “always”  “condom users”

  • “never”  “non-condom users”

    Consistent condom use

    Proportion of “condom users” who reported either

  • “always”  “consistent” use of condoms

  • “sometimes”  “inconsistent”

  • “never” used were excluded from analysis

    • Data Analysis

      - descriptive

      • Frequency tables, mean, median, proportions

        - univariate analysis

      • t-test was used for continuous variables

      • chi-square test for categorical variables

        - multivariate analysis

      • Stratified by sex for both condom use and consistency of use

      • Included both significant and insignificant variables from univariate

    Discussion
    Discussion years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

    1.Condom use rateconsistent with other studies

    • Though its low, indication that HIV/AIDS awareness campaigns and programmes are having a positive effect

      [Shisana et. al HSRC Study 2002; SADHS 2003]

      2. Significant differences in condom use and consistency of use between males and females

    • male-determined method

    • high rate of modern non-barrier contraception use among females

    • Barriers to access of condoms for young girls – attitudes, norms

      [Garenne et al 2004; Morroni et al 2003]

      3. Consistent condom use decreases with age

    • formation of more stable relationships intended to lead to marriage

    • Need for children


    Discussion1
    Discussion… years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

    4. Owning more assets a positive determinant of condom use

    • the better the young adults are socio-economically the better they relate in relationships [Kaufman et al 2004]

    • Affordability of condoms [MacPhail, Campbell 2001]

      5. Lower condom use in females, and consistent use in males, within marital relationships

    • condom use varies with the type of relationships, trusting partner

      [Maharaj; Cleland 2004; Gabriela et al 2005; Prata 2005]

      6. Older partner associated with lower condom use

    • Age differentials and gender power inequalities in sexual relationships which affect relationship control in negotiating for safer sex

      [Gregson et al 2002; Glynn et al 2001]


    Discussion2
    Discussion… years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

    7. Condom use more likely with those not residing with partners

    • an indication of some risk assessment and taking precautions with partners who do not reside close to them

      8. Having a +ve or unknown HIV status was associated with more likelihood to use condoms

    • possible reasons for increased condom use:

      • a high perception of risk

      • high knowledge of HIV prevention;

      • health service accessibility

      • exposure to HIV/AIDS awareness programmes

      • VCT counseling to prevent re-infection or infection of partner.

        [Maharaj; Cleland 2004; Simbayi et al 2005]


    Conclusion
    Conclusion years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

    1. Positive determinants of condom use and consistency:

    (1) not residing with partner (2) having more assets

    (3) +ve/unknown HIV status

    2. Negative determinants of condom use and consistency were:

    (1) being female (2) increase in age

    (3) marital relationship (4) having an older partner

    Research recommendation:

    Further investigation should be done on other behavioral factors eg power relations, substance use, cultural beliefs and norms not investigated in this study


    Policy programme recommendations
    Policy & Programme Recommendations years in Africa Centre DSA, KwaZulu Natal, South Africa, 2005

    1. Develop a strategy to promote gender equality and empowerment of women to reduce poverty that will give a synergy effect to combat HIV/AIDS [United Nations Millennium Development Goals]

    2. Promote consistent use of condoms with both marital and non-marital relationships especially where HIV status of partner(s) is unknown

    3. Promote correct and consistent condom use and encourage youths to go for VCT a significant reduction in HIV prevalence has not yet been observed

    4. Public health education should target young adults and discuss the evidence of the extent of HIV transmission within older partners relationships

    5. Develop programmes e.g. micro-financing to improve the SES of young adults especially women to create income and reduce economic dependency, hence improve their negotiation skills
