Prevention Summit 2008


The kenya aids indicator survey 2007
The Kenya AIDS Indicator Survey 2007

  • Nationally-representative HIV serosurvey

  • ~18,000 individuals from nearly 10,000 households

  • Includes older adults age 50-64

  • Prevalence of HIV, HSV-2 and syphilis

  • Coverage of HIV services


4 components of kais
4 Components of KAIS

  • Household Questionnaire

  • Individual Questionnaire

  • Blood Draw

  • Return of Result


Differences from kdhs 2003
Differences from KDHS 2003

  • KAIS allows

    • examination of older adults 50-64 years old

    • comparisons of persons’ perceived HIV status to actual HIV status

    • HSV-2

    • Return of results

    • CD4 counts measured

  • KAIS-KDHS comparisons restricted to men and women 15-49





Dramatic disparity in hiv prevalence across provinces

From prevalence to prevention assessing key domains of prevention efforts in kenya
From Prevalence to Prevention: in KenyaAssessing Key Domains of Prevention Efforts in Kenya


Key concerns of current prevention efforts
Key Concerns of in KenyaCurrent Prevention Efforts

  • HIV testing

  • Knowledge of HIV status and disclosure between partners

  • Partner HIV discordance

  • Male circumcision

  • HIV awareness and knowledge

  • Youth sexuality

  • Older adults


Hiv testing
HIV TESTING in Kenya

  • Prevention Relevance

    • Increase accurate knowledge of status, and reduce transmission/acquisition risk

  • Prevention Goal

    • Increase the number of persons testing, particularly among those at higher risk of HIV transmission/acquisition






But should testing rates differ given hiv prevalence
. . . but should testing rates differ increased ANC testinggiven HIV prevalence?


Testing summary
Testing: Summary increased ANC testing

  • Trend is improving, but long way to go from testing target

  • ANC testing has increased among pregnant women

  • Acceptability of home testing is high

  • Testing among men and in rural areas lagging

  • Gap in testing among older adults

  • Testing gap in high prevalence provinces


Knowledge of hiv status disclosure
Knowledge of HIV Status & Disclosure increased ANC testing

  • Prevention Relevance

    • Knowledge of serostatus and proper disclosure to sexual partners can help reduce new infections

  • Prevention Goals

    • Increase knowledge of serostatus

    • Increase disclosure between sexual partners

    • Increase condom use when serostatus is unknown


82 of hiv adults do not know they are hiv infected
82% of HIV+ adults do not know increased ANC testingthey are HIV infected

Did Not Report Status

Correctly reported HIV positive

Never Tested

Believed themselves uninfected based on last test

82%

15-64 year olds who were KAIS laboratory-confirmed HIV infected, n=1104


Most people do not know their partners status
Most people do not know their partners’ status increased ANC testing

  • Never tested: 89% do not know partners’ status

  • Tested and believe themselves negative: 60% do not know partners’ status

  • Reported HIV positive: 36% do not know partners’ status



Knowledge of status disclosure summary
Knowledge of Status & Disclosure: Summary status

  • Most HIV+ persons do not know they are infected.

  • Most persons do not know the HIV status of their partners.

  • Consistent condom use is low.

  • Those who know they are HIV+ are more likely to know HIV status of partners.


Hiv discordance
HIV Discordance status

  • Prevention Relevance

    • Long-term discordant couples are at higher risk of HIV transmission/acquisition due to frequency of sexual contact

  • Prevention Goal

    • Increase awareness of discordance between couples

    • Promote safer sex practices among serodiscordant couples


Discordance in kenya
Discordance in Kenya status

6% of all married/cohabitating couples are HIV discordantNearly 400,000 discordant couples in Kenya (200,000 in Nyanza and RV)Nearly 50% of all married/cohabitating HIV+ men and women have an HIV uninfected partner


Condom use with married/cohabitating partners is highest among positives who correctly reported their HIV status


Male circumcision
Male Circumcision among positives who correctly reported their HIV status

  • Prevention Relevance

    • Research suggests that male circumcision is associated with substantially lower HIV acquisition for men.

  • Prevention Goals

    • Increase awareness of potential benefits of circumcision

    • Promote voluntary circumcision among adult men

    • Encourage parents to have male childrencircumcised


Circumcision is associated with lower individual hiv risk among men
Circumcision is associated with lower individual HIV risk among men

Among men age 30-54 who are not circumcised 30% are HIV infected


Hiv knowledge attitudes
HIV Knowledge & Attitudes among men

  • Prevention Relevance

    • Increased knowledge of HIV should help promote risk-reducing behaviors

    • Reduced stigma will support secondary HIV prevention through care and treatment of infected individuals

  • Prevention Goals

    • Increase HIV knowledge in general public and high risk populations

    • Decrease stigma of HIV throughout population


Radio is the most common source of hiv information
Radio is the most common source of HIV information among men

Top 5 sources of information, 15-64


Knowledge questions
Knowledge Questions among men

  • 9 questions on general acquisition/transmission

    • “Can people reduce their chance of getting the AIDS virus by using a condom every time they have sex?”

    • “If a woman has the virus that causes AIDS, does her sexual partner always have the AIDS virus, almost always, or only sometimes?”

  • 3 questions on mother-to-child transmission pathways

    • “Can the virus that causes AIDS be transmitted… during pregnancy?”


School education is associated with comprehensive hiv knowledge
School education is associated with comprehensive HIV knowledge

  • Of the 12 major questions

    • 56% of men and women answered 9 or more correctly

    • 40% answered 5-8 items correctly

    • 4% answered fewer than 5 correctly

  • Educational background was an important determinant of comprehensive HIV knowledge

    • 19% of those with no primary education answered fewer than 5 items correctly, compared to

    • 1% of those who completed primary school or beyond




Attitudes questions
Attitudes Questions differences in prevalence

  • 70-90% agreed with the following individual statements

    • “I would buy fresh vegetables from a vendor who has HIV”

    • “I would not want the status of an HIV-positive family member to remain secret”

    • “I am willing to care for a relative with HIV at home”

    • “I believe an HIV-positive teacher should be allowed to continue teaching”


Among women there is an increase in accepting attitudes
Among women there is an increase in accepting attitudes differences in prevalence

Percent agreeing with all 4 items, ages 15-49


Knowledge attitudes summary
Knowledge & Attitudes: Summary differences in prevalence

  • Radio is the most common means of reaching people with HIV information

  • Comprehensive knowledge was low, especially among those with little formal education

  • HIV knowledge alone is not associated with reduced HIV infection

  • PMTCT knowledge is growing for women

  • Stigma remains a challenge, but improvements are evident among women


Youth sexuality age 15 24
Youth Sexuality (age 15-24) differences in prevalence

  • Prevention Relevance

    • Delayed initiation and safer sex during early sexual development can help reduce HIV acquisition

  • Prevention Goals

    • Increase age of sexual initiation

    • Increase condom use among youth


Marriage and early sexual initiation are associated with higher hiv prevalence among young women
Marriage and early sexual initiation are associated with higher HIV prevalence among young women

Very few young men were married (n=228). Youth, 15-24


Some declines in age of sexual initiation evidence
Some declines in age of sexual initiation evidence higher HIV prevalence among young women


Youth sexuality summary
Youth Sexuality: Summary higher HIV prevalence among young women

  • Marriage at young ages is strongly associated with HIV prevalence

  • Some decline in proportion of men having sex by age 15

  • Few young women have sex with men 10 or more years older


Older adults a new prevention area 50 64 year olds
Older Adults: higher HIV prevalence among young womenA New Prevention Area(50-64 year olds)


Hiv in older adults
HIV in Older Adults higher HIV prevalence among young women

  • 85% of older adults have never tested for HIV

  • 88% of older adults do not know the HIV status of their marital/cohabitating partners

  • Condom use is very low

    • Less than 2% report consistent condom use with marital/cohabitating partners


Hiv in older adults cont
HIV in Older Adults (cont.) higher HIV prevalence among young women

  • Older women have higher proportion of undiagnosed HIV infection

  • HIV is almost 3 times higher among formerly married older adults (widowed, separated, divorced) than those currently married


Lessons learned
Lessons Learned higher HIV prevalence among young women

  • Know your status; know your partners’ status

    • Need for ‘repeat’ testing and disclosure

    • Condom use remains low

  • Re-evaluate common perceptions of ‘high risk groups’

    • Married couples

    • Uncircumcised men

  • Older adults need to be targeted as much as our focus on youth
