The review analyses 19 National AIDS Strategic Plans (NSPs) in the Asia-Pacific region to determine the amount of attention paid to key populations, particularly young key populations (YKP). More than 40 sub-categories were used for the analysis covering NSP development and review; content and operationalization of the plan; and by key population/young key population. The study drew on existing reviews of NSPs; guidance documents on comprehensive packages for key populations; and the UNAIDS HIV and AIDS Investment Framework.
