The Government of Kenya conducted the second AIS (KAIS 2012) among children and adults aged 18 months to 64 years to evaluate HIV care, treatment, and prevention programmes and to inform new strategies to respond to the HIV epidemic in Kenya.
Abstract
From October 2012 to February 2013, the Government of Kenya conducted the second AIS (KAIS 2012) among children and adults aged 18 months to 64 years to evaluate HIV care, treatment, and prevention programmes and to inform new strategies to respond to the HIV epidemic in Kenya.
KAIS 2012 differed from KAIS 2007 by including:

Children aged 18 months to 14 years in the sample to estimate the number of HIV-infected • children and the number in need of HIV treatment.
A paediatric module to describe testing and clinical characteristics of children aged 18 months • to 14 years.
A behavioural interview for young adolescents aged 10 to14 years. •
An expanded behavioural module on adult HIV risk behaviour, including transactional sex, drug • use, anal sex, and correct and consistent condom use.
An opportunity for survey participants to receive home-based testing and counselling (HBTC) to • learn their HIV status at the conclusion of the survey and, for persons found to be HIV-infected, in-home measurement of CD4+ T-cell counts to immediately determine treatment needs.
Viral load testing for all HIV positive samples. •

The specific objectives of KAIS 2012 were to:
Determine HIV prevalence among persons aged 18 months to 64 years. •
Describe the socioeconomic and behavioural risk factors associated with HIV infection. •
Determine the incidence of HIV infection among persons aged 18 months to 64 years. •
Determine need and use of HIV care and treatment services among HIV-infected persons aged • 18 months to 64 years.
Determine the use of HIV prevention services among persons aged 18 months to 64 years.•

Sampling

Sampling Procedure
The survey used two-stage stratified cluster sampling where the first stage selected 372 out of 1,800 clusters from the Kenya National Bureau of Statistics (KNBS) household-based sampling frame and the National Sample Survey and Evaluation Programme (NASSEP V) [2] using probability proportional to size (PPS) method. The second stage randomly selected a sample of 25 households in each cluster from a roster of households in the cluster using systematic random sampling.
Households that were eligible for the child sample (individuals aged 18 months to 14 years) were pre-selected during the sampling phase. During data collection, if a pre-selected household did not have an eligible child, the next pre-selected household was visited until all pre-selected households in the cluster with at least one eligible child were identified.
The sample size was calculated to provide representative national, regional, urban and rural estimates of HIV infection among adults and adolescents aged 15 to 64 years and national HIV prevalence estimates for children aged 18 months to 14 years. The target sample size was 23,896 for women and men aged 15 to 64 years and 8,226 for children aged 18 months to14 years. Table 1 below shows the distribution of sampled clusters and households by region.
Response Rate
Participation rates in KAIS 2012 were high Of the 9,300 households sampled, 9,189 (99%) were eligible for the survey, and 87% of eligible households completed household-level surveys. Rural households (89%) had higher household interview response rates than urban households (85%).

Of 16,383 eligible persons aged 15-64 years, 13,720 (84%) completed adult interviews. Response rates for adult interviews were higher among women (89%) compared to men (77%). Response rates for blood draw were similar among women and men (85% vs. 84%). Urban residents were less likely to provide a blood specimen compared to rural residents (81% vs. 87%). There were a total of 2,131 children aged 10-14 years eligible for an interview; of those, 80% completed interviews. The blood response rate for all children aged 18 months to 14 years was 69%.
Weighting
The sampling weights were computed to correct for unequal probability of selection to provide survey results that were representative of the larger population, and to adjust for non-response. All results presented in thHousehold weighte report are based on weighted estimates, except for the survey response rates .

Data Collection Mode
Computer Assisted Personal Interview [capi]
Supervision
Data collection teams were regularly supervised by teams of national supervisors with representation from different KAIS 2012 collaborating institutions. These supervision teams visited the field teams across the country to deliver survey supplies, perform quality checks on data completeness, provide technology support, assess mobilization efforts, and help address challenges to data collection. Supervision reports were circulated to the KAIS 2012 technical working group for response to any issues.

Questionnaires

Questionnaires
The household questionnaire provided information on all eligible members within the household. The household questionnaire also collected data on the support of orphans and vulnerable children within the household, the physical and sanitary conditions of the home, household possessions and household food security. Adult questionnaires (male and female) to persons aged 15 to 64 years that collected information on demographic characteristics; reproductive and children's health; sexual behaviour; HIV-related knowledge and attitudes; HIV testing; injections and blood transfusions and donations; circumcision (for men); non-prescription drug use; and migration. Children aged 10 to 14 years were administered a questionnaire that collected information on demographic characteristics; knowledge about and attitudes toward HIV; sexual behaviour; HIV prevention, care, and treatment services; and alcohol and drug use.
Data were recorded on portable net book computers (Mirus Innovations, Mississauga, Ontario, Canada), using software specifically designed for the KAIS questionnaires.
The survey was conducted in various languages but the main ones were Swahili and English.

Data Processing

Data Editing
Data cleaning was conducted using SAS version 9.3 (SAS Institute Inc., Cary, North Carolina, USA). Laboratory data were cleaned and merged with the final questionnaire database using unique specimen barcodes and study identification numbers.
Other Processing
All field data collected were transmitted to a KAIS 2012 central server using a secure virtual private network and stored in Microsoft SQL Server 2008 (Microsoft Corporation, Redmond, Washington, USA). Where wireless networks were not available, supervisors uploaded the data manually on secure data cards during regular supervision visits
