Exposure to interventions
Definition
Denominator : Number of respondents
reporting having been
exposed to specific HIV
prevention interventions
Numerator :
Total number of respondents
surveyed.
Measurement tools
Adult questionnaire Section 10
At the data analysis stage, exposure to
interventions may be associated with lower
risk behavior. It is not possible to conclude
from repeat cross sectional surveys such as
BSS that the exposure is the cause of the
behavior change, since there may have been
other factors affecting risk behavior. Taken
together with program process and output
indicators, however, exposure data can help to
clarify whether exposure to a program may
plausibly have contributed to any observed
changes in behavior.
What it measures
The purpose of this indicator is to document
the reach of specific HIV prevention efforts
in the population of interest. Increasing the
coverage of intervention efforts to levels
that can actually impact on the risk of HIV
transmission can be a tremendous challenge
for public health workers. A rise in this
indicator over time measured progress towards
achieving coverage of specific interventions in
the sub-populations that are the intended
beneficiaries of the programs.
How to measure it
The indicator can be constructed for many
different elements of programming for adult
groups. These may range from recall of IEC
messages to use of STI care services. Questions
will obviously have to be situation-specific, and
must be developed to meet the surveillance
and program information needs of each
country or region.
