Socio-behavioral Determinants: A Necessary Element Of HIV Surveillance

This presentation explores the role of socio-behavioral determinants in HIV surveillance, based on the experiences of South Africa. It discusses the use of biomarkers, prevalence, incidence, ARV testing, and themes not usually included in population surveys. The presentation also provides examples of how socio-behavioral items were linked to HIV status.

  1. Socio-behavioral Determinants: A Necessary Element Of HIV Surveillance Experience of South Africa Olive Shisana, Sc.D CEO Human Sciences Research Council (HSRC)

  2. Presentation Format Introduction • Bio-markers • Prevalence • Incidence • ARV testing • Themes not usually included in population survey questionnaire • Present question/item and give example of how socio-behavioral item was linked to HIV status • Conclusion

  3. Introduction • Survey of 15 000 HH is done every 3 years; now on third wave using multi-stage cluster sampling • Four people selected per household (<2, 2-14, 15-24, 25+) & return to HH maximum 4 times • Preceded by qualitative study in two waves • Collect socio-behavioral. communication and HIV biomarkers • Collect contextual questions like geotype, marital status, employment status, social grants, poverty • Generate socio-behavioral, epidemiological curve, identify high risk groups • Perform detailed response analysis

  4. Eg of Qualitative research:AIDS Stigma • “How do you question your partner?… Your wife…yes… your husband. …"Honey! Use a condom because I don't trust you. You know because you might have AIDS! … How do you put that? … How do you ask your partner that?”- Muslim man

  6. HIV Prevalence By Geotype, South Africa, 2005

  7. ARVs • Do you currently have any of the following illnesses (diagnosed; if yes are you currently taking medicine? If yes, names of medicines • ARV data is collected to help interpretation of HIV prevalence and prevent BED incidence misclassification

  8. Themes Not Usually Included In Population Survey Questionnaire • HIV risk perception • Alcohol and substance use • Perceptions of government policies and • Perception of health care system • Violence in households • Media and communication • PMTCT (children under 2)

  9. HIV Risk Perception On a scale of 1 to 4 (with 1 being low and 4 being high), how would you rate yourself in terms of risk of becoming infected with HIV?

  10. Low risk 30 23.1 High risk 20.8 25 17.4 20 HIV Prevalence (%) 12.8 15 10.1 7.5 10 5 0 Male Female Total Self Perceived Risk Of HIV Among Respondents Aged 15 Years And Older By Sex And HIV Prevalence, South Africa 2005

  12. Alcohol Use 2

  13. Alcohol Use 3 Have you or someone else been injured as a result of your drinking? Has a concerned relative, friend, doctor or other health worker ever suggested that you should cut down on your drinking?

  14. Alcohol Risk Status And HIV Status, South Africa 2005 Chi-square:17.6, p <0.01)

  15. Binge Drinking And HIV Status, South Africa 2005 Chi-square:12.5, p <0.05

  16. Use Of Other Substances Have you ever used one of the following substances in the past three months?

  26. HIV positive child under 2 given cotrimoxazol PMTCT noted on the road to health card/growth chart Child previously tested for HIV Where child was born (hospital, clinic, home) Attendant at birth (doctor, midwife, etc) Breastfeeding: length and by whom Supplementary food: what and when Where child was seen: hospital, clinic, doctor (public/private) Mother’s ANC visits and trimester for first care and number of visits Mother offered HIV test during ANC visits Child previously tested for HIV Child scarified Vaccinations PMTCT items

  27. 4. Conclusion 1 • It is critical to measure HIV prevalence and incidence in all age groups to assess adequacy of response to the epidemic • Linking socio-behavioral items with HIV helps in understanding the dynamics of the epidemic • Measuring ARV use is important to interpret prevalence figures and also to correct for HIV incidence • Health questions help in understanding the ability of the health care system to cope with HIV/AIDS burden

  28. Conclusion 2 • Assessing public perceptions on government’s response is an important advocacy tool. • Collecting information on communication help to identify program reach and source of information • Can track PMTCT program implementation • Data are used for surveillance, program evaluation and also for research purposes
